    we all care about the weather and nobody
  • 00:00:01
    wants to to have the weather get the
  • 00:00:04
    best of them one of the most devastating
  • 00:00:05
    aspects of hurricanes is storm surge you
  • 00:00:07
    look at what hurricane Helen just a few
  • 00:00:09
    weeks ago did it was a massive hurricane
  • 00:00:11
    it was 500 mil across I can give you the
  • 00:00:14
    best forecast in the world I can give
  • 00:00:16
    you plenty of lead time but it's your
  • 00:00:18
    decision to evacuate and we can't
  • 00:00:21
    control that and will we need a category
  • 00:00:23
    six because these category fives keep
  • 00:00:26
    getting bigger and bigger but it's a
  • 00:00:27
    storm we've never seen before when are
  • 00:00:29
    we getting to category
  • 00:00:31
    [Music]
  • 00:00:35
    six this is Star Talk Neil degrass Tyson
  • 00:00:39
    your personal astrophysicist got with me
  • 00:00:42
    Chuck nice Chucky baby how you doing hey
  • 00:00:44
    Neil So Chuck today's topic is the
  • 00:00:47
    weather ah excellent yes that's supposed
  • 00:00:51
    to be the safest thing to talk about
  • 00:00:53
    with anyone right no no longer oh no I
  • 00:00:57
    guess not very good point no longer very
  • 00:01:00
    good point well we know that it's
  • 00:01:02
    extreme and if we comb the Earth to find
  • 00:01:05
    who's the top weather person that's
  • 00:01:08
    gonna be Sam Champion WABC news he's
  • 00:01:13
    amazing it's it's gonna yeah every every
  • 00:01:16
    local news has their person who they are
  • 00:01:18
    certain is like the best weather
  • 00:01:20
    forecaster there is but we can go above
  • 00:01:22
    the mall because we're star and we have
  • 00:01:24
    access and we brought in the
  • 00:01:28
    chief chief head honcho of Noah the
  • 00:01:32
    National Oceanic and Atmospheric
  • 00:01:34
    Administration Dr Richard spinrad oh my
  • 00:01:38
    gosh Rick how you doing man hey I'm
  • 00:01:40
    doing great Neil Chuck delighted to be
  • 00:01:42
    here thanks let me get your full title
  • 00:01:45
    straight here the under Secretary of
  • 00:01:48
    Commerce for oceans and atmosphere and
  • 00:01:51
    that's a different title from being Noah
  • 00:01:53
    administrator is that right yeah
  • 00:01:55
    actually my full title will probably
  • 00:01:57
    take the full duration of this show but
  • 00:01:59
    it is the under Secretary of Commerce
  • 00:02:01
    Roan and atmosphere and the
  • 00:02:03
    administrator of Noah the National
  • 00:02:05
    Oceanic and Atmospheric Administration
  • 00:02:07
    so it's really two hats in this job and
  • 00:02:10
    we're reminded that Commerce which is a
  • 00:02:12
    huge branch of the US government cares
  • 00:02:14
    about climate and weather and because
  • 00:02:17
    goods and services are delivered through
  • 00:02:19
    the air on the waters over the land and
  • 00:02:23
    our relationship with climate is deeply
  • 00:02:26
    impacted yeah like Commerce and um the
  • 00:02:31
    melting uh ice that is causing Passage
  • 00:02:35
    through uh a near Alaska and where
  • 00:02:40
    there's it's a contested Waters now
  • 00:02:42
    because you have Russia who wants that
  • 00:02:44
    water uh and we of course and China and
  • 00:02:49
    it's all because it was ice and nobody's
  • 00:02:53
    looking at the point that it was
  • 00:02:57
    Ice what was once ice is now open Waters
  • 00:02:59
    it's now water right yeah yeah that's so
  • 00:03:03
    so so tell me a couple of things here uh
  • 00:03:06
    what is your relationship with the Navy
  • 00:03:07
    because obviously they care about oceans
  • 00:03:09
    as well yeah so that's a great question
  • 00:03:11
    because I actually worked for the Navy
  • 00:03:13
    for the first part of my professional
  • 00:03:14
    career and I was is there any part of
  • 00:03:16
    the government you don't work
  • 00:03:18
    for yeah Congress I have not worked for
  • 00:03:21
    congress yet and that probably won't
  • 00:03:22
    happen either uh but Navy I mean
  • 00:03:25
    obviously Navy cares about uh oceans and
  • 00:03:28
    climate and atmosph here uh and it's not
  • 00:03:31
    just how they operate their ships
  • 00:03:32
    they're going to be concerned about what
  • 00:03:34
    the impacts of climate are going to be
  • 00:03:36
    for their their bases you know you think
  • 00:03:38
    about norfol where we've got the
  • 00:03:39
    Atlantic Fleet and sea level rise
  • 00:03:41
    impacting the operations uh at the base
  • 00:03:44
    there it's an important element of Naval
  • 00:03:46
    operations and North Virginia yeah north
  • 00:03:49
    of Virginia yeah but I could say the
  • 00:03:50
    same thing about just any just about
  • 00:03:52
    anywhere the Navy operates they do care
  • 00:03:54
    about the Shor side facilities uh but
  • 00:03:56
    they also care about the ability to fly
  • 00:03:59
    uh and carry out their missions and
  • 00:04:01
    obviously I mean one of the strongest
  • 00:04:03
    components for Navy is understanding how
  • 00:04:05
    the ocean uh changes what are the
  • 00:04:07
    Dynamics of the ocean how does that
  • 00:04:08
    affect ships and submarines right and
  • 00:04:11
    also uh last I checked there's several
  • 00:04:14
    whole countries in the in the South
  • 00:04:17
    Pacific where the average sea level is
  • 00:04:20
    just only a few feet the aage elevation
  • 00:04:23
    of the land is only a few feet above sea
  • 00:04:25
    level so if we start melting out
  • 00:04:27
    glaciers we'll lose entire countries
  • 00:04:29
    creating is what do they call it climate
  • 00:04:31
    refugees this exactly exactly and and
  • 00:04:35
    this is not some sort of theoretical
  • 00:04:36
    thing that'll happen a thousand years
  • 00:04:38
    from now the sea level rise uh rate that
  • 00:04:41
    you're alluding to has increased
  • 00:04:42
    dramatically when I when I was a grad
  • 00:04:45
    student you know few decades back we
  • 00:04:47
    would talk about sea level rises being
  • 00:04:49
    say 1 to three millimeters per year in
  • 00:04:51
    some places it's doubled or tripled and
  • 00:04:54
    so consequently some of these nations
  • 00:04:56
    are actually going to be eliminated
  • 00:04:59
    before the end of this Century they'll
  • 00:05:00
    actually be underwater right yeah whole
  • 00:05:04
    islands whole island nations that will
  • 00:05:06
    disappear whole island nations and I
  • 00:05:10
    tell me of course everyone cares about
  • 00:05:13
    the weather although climate change has
  • 00:05:15
    been politicized as we all know recently
  • 00:05:18
    i' I'd like to remind people that Noah
  • 00:05:21
    was founded in the year uh
  • 00:05:24
    1970 and it was signed into law by a
  • 00:05:26
    Republican president so the
  • 00:05:29
    politicization
  • 00:05:30
    of climate um to me feels like a very
  • 00:05:33
    recent phenomenon because clearly we all
  • 00:05:36
    care about the weather and nobody wants
  • 00:05:38
    to to have the weather get the best of
  • 00:05:40
    them in any part of their life or or or
  • 00:05:43
    job yeah I think the the a lot of the uh
  • 00:05:46
    making it a political issue comes from
  • 00:05:48
    trying to figure out who's whose fault
  • 00:05:50
    this is you know who do we get to blame
  • 00:05:52
    for this the the thing about Noah is
  • 00:05:55
    that our mission is very much looking to
  • 00:05:57
    the Future we're about predictions and
  • 00:05:58
    projections and so for us it's less
  • 00:06:01
    about hey who caused this problem and
  • 00:06:03
    more about how well can we predict what
  • 00:06:06
    the change is going to be in the future
  • 00:06:08
    we talk about that's what people hold
  • 00:06:10
    you to because they're trying to make
  • 00:06:11
    decisions based on your predictions
  • 00:06:13
    however you you have a moving goalpost
  • 00:06:15
    at all times Rick because quite frankly
  • 00:06:18
    what happens is um these projections are
  • 00:06:23
    modled on what we have now okay but the
  • 00:06:28
    variable is is um do we increase the
  • 00:06:33
    amount of fossil fuel that we're burning
  • 00:06:36
    because I mean that's really the issue
  • 00:06:38
    so as you have fossil fuel burning
  • 00:06:41
    coming online that changes everything
  • 00:06:43
    that you guys said was going to happen
  • 00:06:46
    for instance um the predictions that
  • 00:06:48
    were made previous to now um basically
  • 00:06:54
    everybody's like oh yeah well they're
  • 00:06:55
    all wrong but first they were saying
  • 00:06:57
    they're going to be wrong because it's
  • 00:06:58
    not going to happen now they're saying
  • 00:07:00
    wrong because it's happening much
  • 00:07:03
    quicker yeah model would normally have a
  • 00:07:07
    future expectation for a rate of CO2
  • 00:07:11
    increase or a rate of anything isn't
  • 00:07:12
    that right uh Rick yeah that's right and
  • 00:07:15
    and this is what climate scientists
  • 00:07:17
    would call the Assumption of
  • 00:07:19
    stationarity that is to say that things
  • 00:07:21
    now are what they're going to be in the
  • 00:07:22
    future and it's not and that's the whole
  • 00:07:25
    point is so how do you take the models
  • 00:07:27
    that you were talking about Neil and uh
  • 00:07:30
    initialize them put the data in up front
  • 00:07:33
    to start the model what assumptions do
  • 00:07:35
    you make about how those conditions are
  • 00:07:37
    going to change in a year in 10 years in
  • 00:07:40
    20 years that's the challenge we have in
  • 00:07:43
    front of us but we're getting really
  • 00:07:44
    good and improving the skill on those
  • 00:07:47
    models now Rick have you has your scope
  • 00:07:50
    been uh I'm wondering
  • 00:07:52
    it I think when Noah was founded by the
  • 00:07:56
    way I I did a deep dive into this
  • 00:08:00
    hardly anyone certainly not even
  • 00:08:02
    geologists or biologists had ever
  • 00:08:05
    combined ocean and Air in the same sort
  • 00:08:10
    of conversation there were atmospheric
  • 00:08:13
    scientists there were Oceanic scientists
  • 00:08:16
    and the full system the full the full um
  • 00:08:20
    organic system of all these interplaying
  • 00:08:23
    parts it seemed to me only came of age a
  • 00:08:26
    little later when uh computer models
  • 00:08:29
    started having something to say about it
  • 00:08:31
    and so now I what I what I POs to you is
  • 00:08:35
    now what's under Noah purview is also
  • 00:08:39
    space weather like what the sun is doing
  • 00:08:42
    so these these look like land grabs to
  • 00:08:44
    me we're
  • 00:08:46
    spacecraft you started out with just the
  • 00:08:48
    ocean in there now you want like the
  • 00:08:51
    solar system the universe we're going
  • 00:08:53
    for the universe going for yeah Neil
  • 00:08:55
    you're exactly right and it is an earth
  • 00:08:58
    system and the best place to see that is
  • 00:09:01
    in how hurricanes form and grow and move
  • 00:09:05
    you can't predict that without a good
  • 00:09:08
    understanding of the ocean and the
  • 00:09:09
    atmosphere and you know the best example
  • 00:09:12
    on that one was uh Hurricane Katrina
  • 00:09:14
    which as you may remember intensified
  • 00:09:17
    really quickly before it made landfall
  • 00:09:19
    around New Orleans and we now looking
  • 00:09:22
    back no we could have predicted that
  • 00:09:24
    better if we'd had better data from the
  • 00:09:27
    ocean in the Gulf of Mexico
  • 00:09:30
    happen today you would have predicted it
  • 00:09:32
    better than we were able to do back in
  • 00:09:34
    2005 yeah certainly the what we call the
  • 00:09:36
    rapid intensification of the hurricane
  • 00:09:39
    as it made landfall and that's because
  • 00:09:41
    we would look at the whole ocean not
  • 00:09:43
    just the surface of the ocean to put the
  • 00:09:45
    data yeah you guys you guys I mean
  • 00:09:48
    you're not you're being humble Because
  • 00:09:50
    You're Not tooting your own horn about
  • 00:09:52
    this last uh huge storm that we just
  • 00:09:56
    experienced um where the rapid int
  • 00:09:59
    ification was predicted and did happen
  • 00:10:02
    indeed um uh due primarily to the amount
  • 00:10:07
    of moisture that was being held in the
  • 00:10:09
    land mass uh where the storm was uh
  • 00:10:12
    going to Traverse so you know you should
  • 00:10:15
    you should say yeah we didn't do it back
  • 00:10:17
    in 2005 but take this we did it
  • 00:10:20
    now I'm sorry I don't think I don't
  • 00:10:22
    think he speaks that way
  • 00:10:23
    Chu I love the way you said that though
  • 00:10:25
    Chuck because right I that was Rick
  • 00:10:28
    catch us up on on this thing with land
  • 00:10:30
    water and how that is not neutral as as
  • 00:10:35
    a
  • 00:10:36
    forcing as a forcing factor on a
  • 00:10:38
    hurricane that makes landfall what I
  • 00:10:40
    understood there was a recent hurricane
  • 00:10:42
    that saturated the landscape the the
  • 00:10:45
    land and so now when a hurricane makes
  • 00:10:48
    landfall there is sort of latent heat
  • 00:10:51
    available to it from the water that is
  • 00:10:56
    in the saturated ground or because
  • 00:10:58
    normally hurricane would would weaken as
  • 00:11:01
    it goes over the land right yeah it's
  • 00:11:03
    all about temperatures right and so we
  • 00:11:05
    know the temperatures of the ocean in
  • 00:11:07
    this case the Gulf of Mexico are going
  • 00:11:08
    up know the temperatures in the
  • 00:11:10
    atmosphere are going up which means that
  • 00:11:12
    those storms can hold more water and so
  • 00:11:15
    think about it we had hurricane Harvey
  • 00:11:17
    that hit Houston and it dropped five
  • 00:11:21
    feet five feet of rain when I was a kid
  • 00:11:24
    we didn't talk about feet of rain from
  • 00:11:27
    and so now you look at what hurricane
  • 00:11:29
    Helen just a few weeks ago did
  • 00:11:31
    especially in Western North Carolina and
  • 00:11:33
    the damage was water you're absolutely
  • 00:11:35
    right most people think hurricane so
  • 00:11:36
    it's about winds wind in that case it
  • 00:11:38
    was water but in terms of the forcing
  • 00:11:41
    function on the hurricane itself that
  • 00:11:44
    water that's sort of still had had had
  • 00:11:47
    rendered land masses uh soaked are you
  • 00:11:51
    saying that that does not continue to
  • 00:11:53
    play into the other than the water's got
  • 00:11:56
    nowhere else to go I guess you just get
  • 00:11:58
    yeah well that's basically it it it I
  • 00:12:01
    think it's a combination if you've got
  • 00:12:02
    if you've got soaked uh uh terrain from
  • 00:12:07
    previous precipitation prior to the
  • 00:12:09
    hurricane coming in and that Hurricane's
  • 00:12:11
    got more moisture than it would have
  • 00:12:12
    before Helen was also huge it was a
  • 00:12:15
    massive hurricane it was 500 miles
  • 00:12:19
    across uh and that's that's
  • 00:12:22
    significantly larger than most
  • 00:12:23
    hurricanes so large hurricane warm
  • 00:12:26
    Waters so more moisture available the
  • 00:12:28
    ground was already pretty wet and now
  • 00:12:30
    you're just dumping buckets onto a wet
  • 00:12:32
    sponge so it's going to cause a lot of
  • 00:12:34
    flooding why do I have in my notes that
  • 00:12:35
    you also care about the bottom of the
  • 00:12:37
    ocean like what what what what does that
  • 00:12:40
    do for you well there's a hole in the
  • 00:12:42
    bottom of the
  • 00:12:44
    ocean no there's a plug oh that's right
  • 00:12:47
    yeah yeah the bottom of the ocean is
  • 00:12:49
    important because without a bottom of
  • 00:12:50
    the ocean we wouldn't have an ocean I
  • 00:12:52
    guess okay more important I mean so the
  • 00:12:55
    Topography of the ocean is going to
  • 00:12:57
    drive help Drive uh how the currents uh
  • 00:13:00
    especially in coastal environments where
  • 00:13:02
    the water goes how it flows uh it's
  • 00:13:04
    going to impact things like uh
  • 00:13:07
    accentuated tides in areas where you've
  • 00:13:09
    got extreme changes in topography so why
  • 00:13:12
    is this important especially in the
  • 00:13:13
    context of a hurricane probably one of
  • 00:13:16
    the biggest problems one of the most
  • 00:13:17
    devastating aspects of hurricanes is
  • 00:13:19
    storm surge what happens to the water
  • 00:13:23
    the ocean water when it gets close to
  • 00:13:25
    the shore if the Topography is just
  • 00:13:28
    right you can actually funnel that storm
  • 00:13:30
    surge and you can end up with 12 to 15
  • 00:13:34
    feet that's what they got in Tampa Bay
  • 00:13:35
    when uh hurricane Milton hit yeah and
  • 00:13:37
    and Hurricane Sandy hit New York I mean
  • 00:13:40
    I think it was tropical storm Sandy at
  • 00:13:42
    the point it hit New York but that storm
  • 00:13:44
    surge is what took us out it we actually
  • 00:13:46
    call it superstorm Sandy because it was
  • 00:13:48
    both a tropical cyclone and then there
  • 00:13:49
    was an nor Easter component to it as
  • 00:13:51
    well so it was kind of like the worst of
  • 00:13:53
    all factors combined and yeah you're
  • 00:13:55
    right storm surge yeah I you know I grew
  • 00:13:58
    up in New York and mom was living in an
  • 00:14:00
    apartment that got flooded as a result
  • 00:14:01
    of superstorm sanding uh and we did not
  • 00:14:04
    that's interesting that was what 12
  • 00:14:05
    years ago we didn't have the forecast
  • 00:14:07
    down pat
  • 00:14:19
    yet you know having a front row seat to
  • 00:14:22
    Neil's life over the years and also
  • 00:14:24
    being a parent myself I absolutely love
  • 00:14:26
    that quote as parents there's no greater
  • 00:14:29
    gift we can give to our kids than the
  • 00:14:31
    freedom of curiosity and an eagerness to
  • 00:14:34
    always be learning and that's why we

  • 00:15:56
    let's get back to the show so when did
  • 00:15:58
    you start reaching out and caring about
  • 00:16:00
    what the sun
  • 00:16:01
    does um well we've always had that as
  • 00:16:04
    part of our mission I think it's fair to
  • 00:16:07
    say that I mean obviously the sun has a
  • 00:16:09
    luminosity and an energy but but but it
  • 00:16:13
    at the next level the sun cycles and
  • 00:16:15
    there solar storms and so it's not just
  • 00:16:18
    that there's a star there delivering
  • 00:16:19
    energy to your model there are these
  • 00:16:21
    fluctuations in the energy to the model
  • 00:16:23
    that now you guys seem to car about yeah
  • 00:16:26
    so the the the Sun is a pretty Dynamic
  • 00:16:30
    uh object and uh it goes through these
  • 00:16:33
    Cycles right and we're actually in the
  • 00:16:36
    middle of one of these 11year Cycles it
  • 00:16:37
    started last year and one of the really
  • 00:16:40
    interesting aspects of that is that the
  • 00:16:42
    sun can occasionally actually send out
  • 00:16:46
    these huge huge coronal mass injections
  • 00:16:50
    which are these charged gases plasmas
  • 00:16:52
    that get ejected from the surface of the
  • 00:16:55
    Sun at a speed of about 1 to 2 million
  • 00:16:57
    miles hour uh they are on the sort of
  • 00:17:01
    positive side the the factors that
  • 00:17:02
    create the beautiful Northern Lights the
  • 00:17:04
    Aurora Borealis but a little bit more
  • 00:17:06
    insidiously they also interact with
  • 00:17:08
    navigation systems they interact with
  • 00:17:11
    electrical grids uh they can affect uh
  • 00:17:15
    Power grids uh they can affect uh
  • 00:17:18
    communication systems and so in fact the
  • 00:17:21
    storm that uh erupted in last May May of
  • 00:17:25
    2024 solar storm solar storm the solar
  • 00:17:27
    storm was category what we call G5
  • 00:17:30
    geomagnetic storm 5 highest uh rank
  • 00:17:33
    storm one of the most severe that we've
  • 00:17:35
    seen in decades but you didn't hear
  • 00:17:38
    about it much well I know you did Neil
  • 00:17:40
    but a lot hear about it and and that's
  • 00:17:43
    because we knew it was coming and in
  • 00:17:46
    years past we might not have known it
  • 00:17:48
    was coming and so we could make change
  • 00:17:51
    what kind of changes airplanes could
  • 00:17:53
    change their their roots in order to
  • 00:17:55
    avoid the impact of the solar storm on
  • 00:17:58
    their GPS systems can you see the actual
  • 00:18:01
    discharge as it makes its way here that
  • 00:18:04
    is so cool yes you can and in fact we
  • 00:18:07
    have just launched uh in June of 2024 we
  • 00:18:11
    launched a new satellite it's a weather
  • 00:18:13
    satellite it's the one that you would
  • 00:18:15
    use when you turn on TV and they show
  • 00:18:17
    you the full disc of what the weather
  • 00:18:19
    patterns are in the East Coast or West
  • 00:18:20
    Coast but this one has a compact
  • 00:18:24
    coronagraph oh and that is the tool I'm
  • 00:18:28
    sorry I you guys lost me Neil said oh
  • 00:18:30
    nice you said you said compact
  • 00:18:33
    coronograph like uh you know like I say
  • 00:18:36
    uh my glasses case it's just like my
  • 00:18:39
    glasses case and I'm like okay what is a
  • 00:18:41
    compact coronagraph I got this so one of
  • 00:18:44
    the great inventions of of the recent
  • 00:18:47
    Century has been the ability to create
  • 00:18:50
    an image of the Sun in a telescope as
  • 00:18:53
    though with a set of Optics as though
  • 00:18:56
    the sun had just been eclipsed by the
  • 00:18:59
    moon oh and when the sun gets eclipsed
  • 00:19:01
    by the moon all the bright stuff is
  • 00:19:03
    blotted out and you see the edge you see
  • 00:19:05
    explosions on the edge right you
  • 00:19:07
    remember when we saw the eclipse this
  • 00:19:10
    recent Eclipse when we were stationed up
  • 00:19:13
    in in Vermont uh you saw these along the
  • 00:19:17
    edge there were these little sort of
  • 00:19:18
    prominences sticking out so imagine
  • 00:19:20
    being able to do that at will right
  • 00:19:22
    rather than waiting around for an
  • 00:19:24
    eclipse and so now Rick you say you put
  • 00:19:27
    one of these in orbit that's cool Yeah
  • 00:19:29
    we actually have that one in orbit there
  • 00:19:30
    is another sensor on the Discover
  • 00:19:32
    satellite which is at the L1 the lrange
  • 00:19:35
    one point um the Earth Sun lrange yes
  • 00:19:40
    exactly okay now Chuck don't we have a
  • 00:19:42
    lrange explainer we do for those of you
  • 00:19:45
    who want to uh really go a deep dive on
  • 00:19:48
    lrange points uh we go all all through
  • 00:19:51
    all l12 34 and it's uh really incredible
  • 00:19:56
    um M5 can't leave out M5 uh
  • 00:20:00
    um clearly I was only a pay attention
  • 00:20:02
    for
  • 00:20:05
    four five's important because we're
  • 00:20:08
    really
  • 00:20:09
    good years all gr points are not made
  • 00:20:12
    equal right but if you want to see how
  • 00:20:15
    you can find perfect equilibrium in the
  • 00:20:17
    solar system uh to me that's what lrange
  • 00:20:20
    point represents I love exactly exactly
  • 00:20:22
    so it depends on which two bodies around
  • 00:20:25
    which you're describing the lrange
  • 00:20:26
    points so so Rick this is the Earth Sun
  • 00:20:28
    lrange points is that correct yeah and
  • 00:20:31
    and as you can well describe by having
  • 00:20:34
    multiple views of the Sun from different
  • 00:20:37
    angles that is to say in Earth orbit and
  • 00:20:39
    then at L1 and at L5 we can look at
  • 00:20:42
    basically the whole threedimensional
  • 00:20:44
    character of the sun because not all of
  • 00:20:47
    these coronal mass ejections are
  • 00:20:48
    necessarily aimed at us so we need we we
  • 00:20:52
    care about them all but at Noah We Care
  • 00:20:55
    mostly about the ones that are going to
  • 00:20:56
    be aimed at us and again do the math
  • 00:20:59
    these things travel in about 1 to two
  • 00:21:01
    million miles per hour Sun's 93 million
  • 00:21:05
    miles away so it's a you know a three to
  • 00:21:08
    four day transit that we can give people
  • 00:21:10
    enough lead time to make preparations
  • 00:21:12
    for a major geomagnetic storm so we can
  • 00:21:15
    imagine a future where we have a colony
  • 00:21:16
    on the moon or Mars uh where those
  • 00:21:19
    neither of those objects have shielding
  • 00:21:22
    from this kind of radiation in the way
  • 00:21:24
    we pretty much do here on Earth with our
  • 00:21:27
    atmosphere and our ozone but they don't
  • 00:21:29
    so presumably they would be deeply
  • 00:21:32
    connected Into Your Capacity to
  • 00:21:36
    predict because then everyone would know
  • 00:21:37
    to run underground or run behind
  • 00:21:39
    shelters this sort of thing so so can I
  • 00:21:42
    ask okay this might be a silly question
  • 00:21:43
    but I'm just asking um so with all your
  • 00:21:46
    equipment because Noah is really a space
  • 00:21:50
    organization I mean you're looking back
  • 00:21:52
    at Earth but all your stuff's up in the
  • 00:21:55
    space no no they got buoys and stuff
  • 00:21:58
    that's true that's true I take it back I
  • 00:22:00
    take it back okay you're absolutely
  • 00:22:02
    right um but when you when you talk
  • 00:22:05
    about these ejections do you move that
  • 00:22:09
    stuff or is that stuff just hardened or
  • 00:22:11
    what do you because I mean radiations
  • 00:22:14
    has got to be like the most damaging
  • 00:22:15
    thing for equipment right yeah you're
  • 00:22:18
    not going to be able to move this I mean
  • 00:22:19
    this is immense amounts of energy but
  • 00:22:21
    what you can do is it's it actually it's
  • 00:22:23
    really similar to our discussion on
  • 00:22:25
    hurricanes we're not going to be able to
  • 00:22:27
    move hurricanes and spite of what some
  • 00:22:29
    people may think but we can make the
  • 00:22:31
    predictions work and we can tell people
  • 00:22:34
    this one's bearing down here on Tampa
  • 00:22:36
    plus or minus 20 miles and you got two
  • 00:22:39
    days to evacuate same thing with space
  • 00:22:42
    weather if we get the picture especially
  • 00:22:44
    if you've got multiple views we can say
  • 00:22:47
    this is going to hit pretty hard in the
  • 00:22:49
    northern part of Quebec or in Asia and
  • 00:22:53
    therefore folks can make adjustments
  • 00:22:55
    they have three days they can power down
  • 00:22:58
    their grids they're electrical grids
  • 00:23:00
    they can revor aircraft so they're not
  • 00:23:02
    going to be affected for navigation
  • 00:23:04
    purposes Chuck asked about the the
  • 00:23:06
    satellites that are already in orbit
  • 00:23:08
    they certainly have susceptibility to
  • 00:23:09
    this and you can't just say hey Bank a
  • 00:23:11
    left or hover over Africa until it's
  • 00:23:14
    clear over Asia right you can't do that
  • 00:23:16
    you can't uh we can Shield some of these
  • 00:23:19
    to a certain extent but what we can do
  • 00:23:21
    is again if we know it's coming we can
  • 00:23:23
    make accommodations with regard to power
  • 00:23:25
    or use another satellite uh to cover for
  • 00:23:28
    the one that most be mo might be most
  • 00:23:30
    vulnerable the sacrifice
  • 00:23:33
    satellite yeah no we don't do that we
  • 00:23:35
    don't put them
  • 00:23:37
    up so there's something called
  • 00:23:39
    unexpected events now I foresee the day
  • 00:23:42
    where no event is unexpected and so no
  • 00:23:46
    one is taken by surprise where are we
  • 00:23:48
    now with regard to Noah's modeling and
  • 00:23:51
    other agencies modeling and things just
  • 00:23:54
    happening taking Everyone by surprise
  • 00:23:56
    there's a really interesting aspect to
  • 00:23:58
    your your question Neil because um
  • 00:24:01
    there's a there's a famous story in
  • 00:24:03
    meteorology it's called Isaac storm in
  • 00:24:05
    fact Eric Larson wrote a great book on
  • 00:24:07
    Isaac storm and it was a hurricane that
  • 00:24:09
    hit galvaston in the year 1900 for the
  • 00:24:12
    folks in galvaston in 1900 that storm
  • 00:24:14
    was an unexpected storm they didn't
  • 00:24:16
    expect it to hit now obviously there's
  • 00:24:18
    never going to be another Isaac storm
  • 00:24:20
    we've improved that there are things
  • 00:24:22
    though that happen uh on much shorter
  • 00:24:26
    time scales and so I would say
  • 00:24:29
    they may not be unexpected like
  • 00:24:31
    tornadoes U but the time that we're able
  • 00:24:34
    to give people to react to them and is
  • 00:24:37
    shorter so right now for tornadoes we're
  • 00:24:40
    looking at an average lead time on most
  • 00:24:42
    tornadoes of about 12 minutes whoa about
  • 00:24:46
    50 years ago the lead time on tornadoes
  • 00:24:50
    was minus five
  • 00:24:52
    minutes okay that doesn't even make any
  • 00:24:55
    sense I'm just saying when the tornadoes
  • 00:24:58
    over I already know there was a tornado
  • 00:25:01
    that's right that's right yeah there is
  • 00:25:05
    something wrong with that picture um
  • 00:25:07
    wait just just to clarify you're not
  • 00:25:08
    talking about the prediction of the
  • 00:25:11
    existence of a tornado you're talking
  • 00:25:12
    about the path a tornado will take once
  • 00:25:14
    it forms yeah yeah the path it's going
  • 00:25:16
    to take and how intense it's going to be
  • 00:25:18
    gotcha yeah and because there are like
  • 00:25:21
    like with hurricanes tornadoes have
  • 00:25:22
    classifications by intensity we have the
  • 00:25:25
    extended fueta scale for tornadoes one
  • 00:25:27
    through five uh and it's the same kind
  • 00:25:29
    of thing so right now we can say we
  • 00:25:32
    think this tornado or this uh this
  • 00:25:36
    aggregation of tornadoes is going to
  • 00:25:38
    take this path and it's probably going
  • 00:25:39
    to be an ef2 and it's probably going to
  • 00:25:41
    hit over here in 15 minutes by the way
  • 00:25:44
    12 minutes 15 minutes is enough time to
  • 00:25:47
    get out of the way of a tornado or or to
  • 00:25:49
    go or underground yeah underground yeah
  • 00:25:52
    so that's an that's incredible how do
  • 00:25:55
    you feel I mean do we have deep resonant
  • 00:25:59
    emotions uh when for example you go to
  • 00:26:02
    see a a movie that you know stormchasers
  • 00:26:06
    movie you know yeah Twisters Twisters
  • 00:26:10
    how how do you let's commiserate
  • 00:26:12
    together here now uh how do you feel
  • 00:26:15
    when you see these films how how much
  • 00:26:16
    effort do they call you and say help us
  • 00:26:18
    get this right or they just make stuff
  • 00:26:20
    up and and and and is it true that in a
  • 00:26:22
    tornado I can actually call a cow as it
  • 00:26:26
    comes by and it goes
  • 00:26:29
    and then
  • 00:26:31
    disappears of course Chuck that's a
  • 00:26:33
    stupid question everybody knows
  • 00:26:36
    that uh we are not using bow Vine
  • 00:26:38
    sensors and tornadoes uh for our
  • 00:26:41
    forecast systems yet
  • 00:26:43
    so the cow could just totally hook you
  • 00:26:46
    up on
  • 00:26:47
    that what is your if mind if I ask what
  • 00:26:50
    is Noah's annual budget uh it's just
  • 00:26:52
    under s billion would you say that
  • 00:26:55
    Noah's effort saves people and lives and
  • 00:27:00
    on a level far beyond the value of that
  • 00:27:02
    budget well I I mean we talk about
  • 00:27:05
    answer is yes Rick you're the head of
  • 00:27:06
    the
  • 00:27:07
    organization for Christ's sake man NE
  • 00:27:11
    answer is yes right thank you
  • 00:27:13
    Rick the uh we talk about lives and
  • 00:27:16
    livelihoods and and Lifestyles so
  • 00:27:18
    property and lives um but certainly
  • 00:27:20
    lives and the only reason I HED is
  • 00:27:23
    because I can give you the best forecast
  • 00:27:25
    in the world I can give you plenty of
  • 00:27:27
    lead time
  • 00:27:28
    but it's your decision to evacuate it's
  • 00:27:31
    your decision to take action and we
  • 00:27:34
    can't control that so we like to think
  • 00:27:37
    that two things one the quality of our
  • 00:27:39
    forecast is getting better and the
  • 00:27:40
    second is the trust by the public in
  • 00:27:43
    that forecast uh and the on onscreen
  • 00:27:46
    meteorologists and emergency managers is
  • 00:27:49
    high enough so that when we say you
  • 00:27:51
    better Evacuate the storm is coming your
  • 00:27:53
    way people actually take that action but
  • 00:27:55
    there's no question I mean I talked to
  • 00:27:56
    you about the the storm in galston in
  • 00:27:59
    the year um 1900 and I think the number
  • 00:28:03
    was something like 10,000 lives were
  • 00:28:05
    lost in that storm wow my that's not
  • 00:28:07
    ever going to happen again in this
  • 00:28:09
    country ever and that's because of the
  • 00:28:12
    quality of the forecast and our ability
  • 00:28:14
    to have the trusted people to make these
  • 00:28:16
    decisions so yeah absolutely we're
  • 00:28:17
    saving and you also affect uh forecast
  • 00:28:20
    for Fisheries right and other sort of
  • 00:28:23
    coastal management of marine food is
  • 00:28:27
    that a so we do Marine forecasts as part
  • 00:28:30
    of what the weather service does and we
  • 00:28:32
    also have responsibility for managing
  • 00:28:34
    marine fisheries uh which means we're
  • 00:28:36
    the ones who do the stock assessments of
  • 00:28:39
    how many fish are out there how healthy
  • 00:28:42
    are the fish how healthy are the
  • 00:28:43
    populations and establish regulations
  • 00:28:46
    for how to sustainably fish for these uh
  • 00:28:52
    uh these fish and maintain a strong
  • 00:28:53
    Seafood economy again we're part of the
  • 00:28:55
    Department of Commerce so it's an
  • 00:28:56
    important economic consideration so with
  • 00:28:59
    respect to what you just said uh what's
  • 00:29:02
    your relationship with other countries I
  • 00:29:04
    know we're a National Organization but
  • 00:29:06
    do you have international affiliations
  • 00:29:08
    like for the typhoon that's raging in
  • 00:29:11
    Taiwan right now or when it comes to
  • 00:29:13
    sustain sustainability of food supply
  • 00:29:15
    like working with China who just doesn't
  • 00:29:17
    give a damn
  • 00:29:20
    so but but what what's your role there
  • 00:29:22
    we we care about our Coastline and our
  • 00:29:24
    and our uh our Oceanic uh prop Oceanic
  • 00:29:29
    property line if you will but if you're
  • 00:29:31
    studying the entire Earth with regard to
  • 00:29:33
    climate do you share your data with
  • 00:29:35
    other countries and are they responsive
  • 00:29:37
    and what's your relationship yeah yeah
  • 00:29:40
    we absolutely can't do our job without
  • 00:29:42
    strong International collaboration and
  • 00:29:44
    that takes a couple of different forms
  • 00:29:45
    there are worldwide organizations as the
  • 00:29:48
    World Meteorological organization of
  • 00:29:50
    which we are a member and in fact the
  • 00:29:52
    head of our national weather service is
  • 00:29:54
    the US Representative to the wo uh and
  • 00:29:57
    it's these are organizations that
  • 00:29:59
    establish uh policies with regard to
  • 00:30:01
    data and yeah all of our Noah data is
  • 00:30:04
    publicly available uh and we use that as
  • 00:30:07
    if you will lever to say to other
  • 00:30:09
    nations hey we're giving you ours why
  • 00:30:11
    don't you give us yours as well so
  • 00:30:13
    there's a lot of collaboration for data
  • 00:30:15
    and they recognize they need our data to
  • 00:30:18
    improve their forecast we need they
  • 00:30:20
    their data to improve our forecast and
  • 00:30:22
    when you start talking about Fisheries
  • 00:30:23
    yeah there's a lot of international
  • 00:30:24
    agreements because a lot of the fish are
  • 00:30:27
    in open ocean Waters and there have to
  • 00:30:28
    be
  • 00:30:29
    agreements and and the Agreements are
  • 00:30:31
    not just about hey how much fish can we
  • 00:30:34
    take sustainably that is to say to allow
  • 00:30:37
    the population of the fish to stay stay
  • 00:30:39
    uh uh healthy but also to try to um be
  • 00:30:45
    the Protectors of those uh Fisheries by
  • 00:30:50
    um enforcing laws against illegal
  • 00:30:52
    unreported and unregulated Fisheries
  • 00:30:55
    what we call iuu fishing uh so that Rees
  • 00:30:58
    a lot of international cooperation
  • 00:30:59
    because you know what it's a big big
  • 00:31:01
    ocean you know it's not the same thing
  • 00:31:04
    but it's it's similar in some ways the
  • 00:31:07
    Artemis Accord which has recently been
  • 00:31:09
    signed by upwards of 30 countries or so
  • 00:31:12
    is a it's a new agreement about conduct
  • 00:31:15
    in space and space exploration signed by
  • 00:31:18
    space fairing Nations it's an active
  • 00:31:21
    Accord that's going on right now and so
  • 00:31:24
    for example if you send a Rover to the
  • 00:31:26
    moon or Mars and you learn something
  • 00:31:28
    about it you would share that with other
  • 00:31:30
    countries so if they send a Rover they
  • 00:31:32
    don't have to make the same mistakes you
  • 00:31:34
    did or that you can collaborate so uh
  • 00:31:37
    it's interesting how the
  • 00:31:38
    internationality of what you do uh
  • 00:31:41
    certainly uh would would contain tap
  • 00:31:44
    rots for doing things cooperatively in
  • 00:31:46
    space there there's yeah and I think
  • 00:31:49
    there's a lot of commonality there and
  • 00:31:51
    the I thought that was going through
  • 00:31:52
    your mind my mind as you were talking
  • 00:31:54
    about the emis Accords Neil is that we
  • 00:31:58
    to have similar kind of agreements for
  • 00:31:59
    making observations in the ocean there's
  • 00:32:03
    no one nation that can cover all of the
  • 00:32:04
    ocean and so uh we have a a major
  • 00:32:07
    program it's called Argo and it's
  • 00:32:08
    basically these uh robots that go
  • 00:32:11
    throughout the ocean and they go up and
  • 00:32:13
    down and all over and they drift around
  • 00:32:15
    and we by International agreement have
  • 00:32:18
    said let's all agree to what these
  • 00:32:20
    robots these floats should look like
  • 00:32:23
    let's all build them to these specs
  • 00:32:26
    let's put all of these things out so
  • 00:32:28
    there's about four or 5 thousand of
  • 00:32:30
    these out there now and they've been
  • 00:32:31
    floating around for decades and let's
  • 00:32:34
    all share the data in a common data
  • 00:32:36
    repository these are those buoys that I
  • 00:32:38
    was thinking about is that right these
  • 00:32:40
    actually dive down so they don't spend a
  • 00:32:42
    lot of time at the surface they they
  • 00:32:44
    float around and then they ascend to
  • 00:32:47
    about 1,000 or 2,000 meters depth they
  • 00:32:50
    collect temperature solinity other kind
  • 00:32:54
    of variables are measured they'll drift
  • 00:32:57
    for about 10 days days out of 2,000
  • 00:32:59
    meters then come back to the surface
  • 00:33:01
    transmit their data through satellite
  • 00:33:03
    Communications to a central repository
  • 00:33:05
    and then dive back down again and start
  • 00:33:07
    you know rinse and repeat basically you
  • 00:33:08
    know that's badass I just have to say is
  • 00:33:11
    yeah now you know there are some Nations
  • 00:33:13
    though they probably got a back door
  • 00:33:15
    like if you find oil don't tell anybody
  • 00:33:20
    else hey Star Talk fans I don't know if
  • 00:33:23
    you know this but the audio version of
  • 00:33:26
    the podcast actually posts a week in
  • 00:33:29
    advance of the video version and you can
  • 00:33:33
    get that in Spotify and apple podcast
  • 00:33:36
    and most other podcast Outlets that are
  • 00:33:39
    out there multiple ways to ingest all
  • 00:33:43
    that is Cosmic on Star talk let's take
  • 00:33:45
    up this subject of climate change for
  • 00:33:47
    the moment so we know I is it the is the
  • 00:33:52
    fraction a third so for every x amount
  • 00:33:55
    of CO2 that goes into the atmosphere
  • 00:33:57
    does the ocean uptake about a third of
  • 00:33:59
    that or some fraction of it yeah yeah
  • 00:34:02
    there's a variety of estimates but
  • 00:34:04
    that's that's pretty close maybe even
  • 00:34:06
    closer to a half but definitely a large
  • 00:34:08
    percentage okay so and the that means
  • 00:34:10
    the dissolved CO2 in the ocean is in
  • 00:34:14
    some form of partial pressure
  • 00:34:17
    equilibrium with the CO2 in the air so
  • 00:34:20
    if we were to stop CO2 production or
  • 00:34:23
    even introduce CO2 scrubbers in the
  • 00:34:26
    atmosphere we will do this but then
  • 00:34:30
    there's less CO2 pressing down on the
  • 00:34:32
    ocean and the ocean says I have to make
  • 00:34:34
    this in make equilibrium out of this and
  • 00:34:36
    it'll start releasing and it gives it up
  • 00:34:38
    to the atmosphere gives it up to the
  • 00:34:39
    atmosphere so is it true that we would
  • 00:34:43
    not see the immediate effects for quite
  • 00:34:46
    some time perhaps decades even if we
  • 00:34:49
    stopped all fossil fuel burning today
  • 00:34:51
    the short answer to your question Neil
  • 00:34:53
    is yes people talk about the flywheel in
  • 00:34:55
    the carbon cycle uh you could stop the
  • 00:34:59
    introduction uh interesting you raised
  • 00:35:01
    the question of actually actively
  • 00:35:02
    removing carbon dioxide from the
  • 00:35:04
    atmosphere which would accelerate the
  • 00:35:07
    the diminishment of excess carbon
  • 00:35:09
    dioxide in the atmosphere but it would
  • 00:35:11
    still be yeah you're right decades
  • 00:35:13
    before we would see the ocean responding
  • 00:35:15
    in Kind part of the uh the problem uh
  • 00:35:20
    with the dynamic you described is that
  • 00:35:23
    the increased carbon dioxide dissolution
  • 00:35:25
    in the ocean manifests as ocean
  • 00:35:27
    acidification
  • 00:35:28
    right pH thing going on okay of course
  • 00:35:32
    yeah and so in that case it's not simply
  • 00:35:35
    a matter of it's not like opening up a
  • 00:35:37
    bottle of of of Coca-Cola and having all
  • 00:35:40
    the CO2 uh go back out of the liquid
  • 00:35:43
    into the atmosphere a lot of this CO2
  • 00:35:46
    has become part of the carbon cycle
  • 00:35:48
    within the atmosphere in in including
  • 00:35:51
    with a decrease in PH and increased
  • 00:35:54
    acidification and that's where you see
  • 00:35:56
    the uh complete bleaching of coral reefs
  • 00:35:59
    and the death of of of these coral reefs
  • 00:36:02
    which by the way are their in entire
  • 00:36:04
    ecosystems in themselves yeah yeah
  • 00:36:07
    that's part of it uh in fact the the
  • 00:36:10
    major contribution to Coral bleaching is
  • 00:36:12
    actually the temperature temperature the
  • 00:36:13
    warming of the water but because of the
  • 00:36:16
    chemical makeup of most corals The
  • 00:36:19
    increased acidification uh is very
  • 00:36:21
    erosive gross of vent corls so when
  • 00:36:24
    people talk about terraforming Mars and
  • 00:36:25
    moving there
  • 00:36:28
    I'm sorry that was just an excellent
  • 00:36:30
    segue Earth be uh my rebuttal to that
  • 00:36:34
    it's not rebuttal my comment on it is if
  • 00:36:37
    we have the power of geoengineering to
  • 00:36:39
    turn Mars into Earth then we have the
  • 00:36:42
    power of geoengineering to turn Earth
  • 00:36:43
    back into Earth you wouldn't need Mars
  • 00:36:46
    right yeah to do that and so that's kind
  • 00:36:48
    of how I how I view that so Rick this
  • 00:36:51
    past hurricane season
  • 00:36:53
    the was it just my imagination or were
  • 00:36:56
    there more category lives kicking in
  • 00:36:59
    than usual and if so is that the new
  • 00:37:04
    normal and what what what is the new
  • 00:37:06
    normal right now today I we're recording
  • 00:37:10
    this in October it's like 75 degrees
  • 00:37:13
    outside uh when it says unseasonably
  • 00:37:15
    warm temperatures today will that soon
  • 00:37:18
    become seasonably
  • 00:37:20
    warm that's unseasonable becomes
  • 00:37:23
    seasonable because that's the new normal
  • 00:37:26
    and will we need a category six because
  • 00:37:28
    these category fives keep getting bigger
  • 00:37:30
    and bigger and it keep saying category
  • 00:37:32
    five but it's a storm we've never seen
  • 00:37:34
    before when are we getting to category
  • 00:37:36
    six Chuck stop poking the bear what
  • 00:37:39
    you're doing I love that question Chuck
  • 00:37:42
    and I will get to it in a minute I but
  • 00:37:45
    what I I do want to say is um yeah I
  • 00:37:48
    keep thinking about uh the New York
  • 00:37:50
    Times Colonist Tom Freedman who said
  • 00:37:52
    it's not global warming it's Global
  • 00:37:54
    weirding weirding and you know and if
  • 00:37:57
    think about it Neil we don't talk global
  • 00:37:59
    warming anymore we talk climate change
  • 00:38:02
    and that's because it manifests in so
  • 00:38:05
    many many different ways and and
  • 00:38:08
    fundamentally fundamentally what we're
  • 00:38:10
    doing is we're putting more energy into
  • 00:38:11
    the system because of the greenhouse
  • 00:38:14
    effect there's more energy coming into
  • 00:38:16
    the system so your question about uh
  • 00:38:18
    what's going to be seasonable or not
  • 00:38:20
    seasonable what are the storms look like
  • 00:38:22
    things are going to be different uh this
  • 00:38:25
    year for example we predicted an above
  • 00:38:29
    normal uh hurricane season and it's
  • 00:38:32
    turning out it is above normal by
  • 00:38:35
    certain measures is that going to become
  • 00:38:37
    The New Normal well I think just logic
  • 00:38:39
    suggests that we can probably see a lot
  • 00:38:41
    more hurricane activity in the future in
  • 00:38:44
    terms of the intensity of storms how
  • 00:38:45
    much water they have with them that sort
  • 00:38:47
    of thing which gets to Chuck's comment
  • 00:38:50
    and that is you know my take is it's not
  • 00:38:52
    about do we need another category a
  • 00:38:55
    category six in the saffer Simpson scale
  • 00:38:57
    want you to name it after him a a Chuck
  • 00:39:00
    hurricane is a category six hurricane
  • 00:39:02
    well there's something wrong with
  • 00:39:03
    calling something a nice hurricane
  • 00:39:05
    that's the no not we'll call it not so
  • 00:39:07
    nice not so nice no you leave out his
  • 00:39:09
    last name just called the Chuck
  • 00:39:11
    hurricane the Chuck
  • 00:39:12
    hurricane what we really need in that
  • 00:39:15
    regard is uh to expand the focus because
  • 00:39:18
    you know the the saffer Simpson scale is
  • 00:39:20
    really a measure of of wind right uh how
  • 00:39:23
    strong are the winds and you see that
  • 00:39:24
    every time hey the winds have just
  • 00:39:26
    gotten to 130 M miles an hour so now
  • 00:39:28
    it's a cat war that kind of thing but
  • 00:39:31
    when you look at what these hurricanes
  • 00:39:33
    are doing we're looking at impacts of
  • 00:39:35
    storm surge I talked about the volumes
  • 00:39:37
    of water from hurricanes like like
  • 00:39:39
    Harvey years ago we need people to
  • 00:39:41
    understand that we should be looking at
  • 00:39:42
    more than just what the peak wind is
  • 00:39:45
    because you could have a cat five with
  • 00:39:47
    really strong 170 m hour winds but it
  • 00:39:50
    may not have the impact that a cat 3 has
  • 00:39:54
    with a large volume of water like
  • 00:39:56
    hurricane h
  • 00:39:58
    we find way for people the full me of
  • 00:40:01
    what the hurricanes are what they look
  • 00:40:03
    and what their imps going to be and let
  • 00:40:05
    me toot your horn for a moment here in
  • 00:40:07
    the
  • 00:40:08
    1989 sequel to Back to the Future titled
  • 00:40:11
    Back to the Future Part Two uh they went
  • 00:40:14
    into the future the year
  • 00:40:17
    2015 and so we're watching this movie in
  • 00:40:20
    1989 and they're they are Imagining the
  • 00:40:23
    year 2015 and there's a point where
  • 00:40:26
    Marty and and
  • 00:40:28
    and Doc get out of the car and Doc puts
  • 00:40:32
    up an umbrella and Marty says what are
  • 00:40:34
    you doing he says oh this is the future
  • 00:40:37
    weather forecasting is now we know the
  • 00:40:39
    exact minute it's going to start to rain
  • 00:40:41
    and right in that instant it starts to
  • 00:40:42
    rain and it stops ready stops and then
  • 00:40:45
    it stops and he puts the umbrella away
  • 00:40:47
    we're not exactly there but of course on
  • 00:40:50
    our smartphones it'll show you when the
  • 00:40:53
    rain is going to begin where you are and
  • 00:40:54
    where it's end that's what I'm saying
  • 00:40:57
    that's true I never even thought of that
  • 00:40:59
    but it's it gives you the time of day
  • 00:41:01
    like 3 p.m. starts yeah in your spot and
  • 00:41:04
    and it tells you how much and how
  • 00:41:05
    intense and Chuck when we were growing
  • 00:41:07
    up it was like all you really want to
  • 00:41:10
    know what what might it rain tomorrow
  • 00:41:12
    because you have a and then they give
  • 00:41:14
    you a 50% chance which means they know
  • 00:41:16
    absolutely nothing right your
  • 00:41:18
    grandmother knew more my badis is acting
  • 00:41:20
    up my shoulder I tell you baby it's
  • 00:41:23
    going to rain tomor my shoulder how for
  • 00:41:26
    all you know Noah's got Grandma's in the
  • 00:41:27
    back
  • 00:41:28
    room yeah
  • 00:41:30
    right e how's your knee I tell you I
  • 00:41:34
    tell you it's going to rain and eel
  • 00:41:36
    predicts the Hurricanes
  • 00:41:38
    exactly well you know it's interesting
  • 00:41:40
    because I was gonna say Neil that yeah I
  • 00:41:42
    do have a couple apps on my phone in
  • 00:41:44
    fact and I use it for just that okay you
  • 00:41:46
    know should we have that picnic now or
  • 00:41:48
    should we wait an hour that kind of
  • 00:41:50
    thing and that's less about the
  • 00:41:51
    prediction and more about the
  • 00:41:53
    observations and so the The Radars that
  • 00:41:56
    we've got the satellites have got so
  • 00:41:57
    much resolution right now that you can
  • 00:41:59
    start doing that you can right within an
  • 00:42:01
    hour or two you can say hey this storm I
  • 00:42:04
    mean I use it all the time when I'm when
  • 00:42:06
    I'm walking my dog I'm saying all right
  • 00:42:08
    should I do it now or should I wait an
  • 00:42:09
    hour so you're say you're saying that's
  • 00:42:11
    because we have real-time observation of
  • 00:42:13
    what's exactly exactly yeah yeah and we
  • 00:42:16
    can uh and tornadoes are a really good
  • 00:42:19
    example you know we've gotten really
  • 00:42:20
    good at observing tornadoes using some
  • 00:42:23
    of the new sophisticated applications we
  • 00:42:26
    use something called dual polarization
  • 00:42:28
    on our weather radars which is in the
  • 00:42:30
    old Radars it was basically just send
  • 00:42:33
    out a signal and see what comes back and
  • 00:42:35
    now we can start manipulating the signal
  • 00:42:38
    looking at the polarization of the
  • 00:42:39
    signal to determine uh is that rain is
  • 00:42:42
    it sleet is it snow and get such good
  • 00:42:46
    resolution that we can say yeah it's
  • 00:42:49
    sleet but we know the temperature two
  • 00:42:52
    miles away is warmer and we can see how
  • 00:42:54
    fast it's coming so in an hour it's
  • 00:42:57
    going to be rain over
  • 00:42:59
    here okay so cool man we actually fly
  • 00:43:02
    through the hurricanes and we've been
  • 00:43:03
    doing that for quite a while we have uh
  • 00:43:06
    two actually more than that we have at
  • 00:43:09
    least three airplanes that we use to fly
  • 00:43:11
    through or over the Hurricanes that's
  • 00:43:14
    the right stuff right there want talk
  • 00:43:17
    right stuff man and I've done that once
  • 00:43:19
    I did it once with our team who you got
  • 00:43:21
    piss off to get that
  • 00:43:24
    job but all fair is Rick if I I I some
  • 00:43:27
    of the math on this if you're standing
  • 00:43:29
    there on stationary Earth and 170 mph
  • 00:43:32
    wind is coming by you that that's going
  • 00:43:34
    to Tumble buses and trucks and the cow
  • 00:43:37
    of course will fly by however um an
  • 00:43:41
    airplane in open air flies 500 600 miles
  • 00:43:45
    an hour way faster than the air in a
  • 00:43:47
    hurricane so is it not as dangerous for
  • 00:43:51
    an airplane as you might otherwise think
  • 00:43:54
    yeah I I'm going to be the first to tell
  • 00:43:56
    you it is a d dangerous thing to do but
  • 00:43:58
    our crews are real Aces they are amazing
  • 00:44:02
    professionals and the equipment that we
  • 00:44:03
    fly we actually fly 50-year-old
  • 00:44:06
    airplanes but we're scheduled to buy
  • 00:44:08
    some brand new ones here soon and we fly
  • 00:44:11
    uh Navy p3s the same airplanes that the
  • 00:44:14
    Navy used to use to find submarines and
  • 00:44:17
    here's the kicker that we fly them high
  • 00:44:19
    enough through the hurricane that yeah
  • 00:44:21
    when you go through the eyewall the
  • 00:44:23
    hurricane where there's extraordinary
  • 00:44:25
    vertical uh wind currents you're going
  • 00:44:28
    to go through several thousand feet of
  • 00:44:31
    uh uh elevation change if you did that
  • 00:44:34
    on a commercial flight to Cleveland uh
  • 00:44:37
    you'd have a real problem and you'd be
  • 00:44:38
    sending a complaint to the airline G to
  • 00:44:40
    be a lot of uh vouchers giving out at
  • 00:44:43
    the end of that flight and and we do it
  • 00:44:46
    repeatedly we'll fly we'll do like a a a
  • 00:44:49
    figure four pattern through the
  • 00:44:50
    hurricane two or three times and then
  • 00:44:53
    the other really cool thing though is we
  • 00:44:54
    don't just fly those aircraft through
  • 00:44:57
    the Hurricanes at say 8 10,000 ft we
  • 00:45:00
    also drop drones from the airplanes so
  • 00:45:04
    that they those drones can then fly at
  • 00:45:07
    the lower altitudes and get all the data
  • 00:45:09
    we need so you know when you talked
  • 00:45:12
    about not just Jo writing you're getting
  • 00:45:13
    data at every turn oh we're getting data
  • 00:45:16
    up the Wu real time it's going back to
  • 00:45:18
    the National Hurricane Center they are
  • 00:45:19
    assimilating those data into the
  • 00:45:21
    predictive models and because of those
  • 00:45:23
    flights the track and intensity
  • 00:45:25
    forecasts have improved by 10 15 20% so
  • 00:45:29
    that real-time message to the guy on the
  • 00:45:30
    beach who says I don't know if I should
  • 00:45:32
    evacuate or not uh has gotten so much
  • 00:45:34
    better look at the look at the tracks
  • 00:45:36
    from Hurricane Milton you saw that two
  • 00:45:38
    three days out we were saying it's gonna
  • 00:45:39
    hit Tampa St Pete and we were spot on y
  • 00:45:42
    they were totally tight so Rick as a
  • 00:45:45
    weather phenomena around the world even
  • 00:45:48
    if it's just simply higher temperatures
  • 00:45:50
    than ever before uh whatever is the
  • 00:45:53
    phenomenon that's stretching the limits
  • 00:45:57
    of what might have been models that were
  • 00:46:00
    comfortably contained within certain
  • 00:46:02
    parameters every time there's an
  • 00:46:04
    unprecedented
  • 00:46:05
    event uh that you didn't predict what is
  • 00:46:09
    what do you have to do with your models
  • 00:46:11
    what what's what's the next step here
  • 00:46:14
    yeah that's a a great question
  • 00:46:16
    especially if you kind of extend it and
  • 00:46:17
    say how does something like AI or
  • 00:46:20
    machine learning artificial intelligence
  • 00:46:21
    and machine learning fit in here um and
  • 00:46:24
    these uh extraordinary events and I
  • 00:46:27
    think some of the heat waves we've seen
  • 00:46:28
    some of the droughts we've seen are
  • 00:46:30
    examples uh they end up providing an
  • 00:46:34
    incredible volume of new data and our
  • 00:46:37
    artificial intelligence applications
  • 00:46:40
    depend critically on what we call
  • 00:46:42
    training data so the data from what has
  • 00:46:45
    happened in the past being used as
  • 00:46:47
    training for the models of the future so
  • 00:46:50
    I would argue when we don't fully
  • 00:46:54
    characterize a particular event with our
  • 00:46:56
    forecast
  • 00:46:57
    but we are able to collect all the data
  • 00:46:59
    from that event we are by definition
  • 00:47:01
    improving our ability to use AI
  • 00:47:03
    techniques machine learning techniques
  • 00:47:05
    except by definition your AI That's
  • 00:47:07
    mining the data will not have data that
  • 00:47:12
    it has never seen that is yet to see
  • 00:47:14
    which is the argument for making sure we
  • 00:47:17
    fully measure and characterize these
  • 00:47:19
    extreme events and so a lot of our
  • 00:47:22
    investment at Noah is building the
  • 00:47:25
    systems that provide uh much more
  • 00:47:27
    intense higher temporal resolution in
  • 00:47:30
    the data for things like extreme
  • 00:47:33
    precipitation one of the main things
  • 00:47:35
    we're trying to do right now it's a
  • 00:47:36
    clarify temporal resolution you can
  • 00:47:38
    think of spatial resolution you know how
  • 00:47:40
    much detail do you have from A to B to
  • 00:47:42
    see in location but temporal resolution
  • 00:47:45
    would be what's happening this hour this
  • 00:47:47
    minute this second and so it's a
  • 00:47:50
    resolution over time in case people were
  • 00:47:51
    wondering everybody wants to know what's
  • 00:47:53
    happening in their neighborhood right
  • 00:47:54
    and a lot of
  • 00:47:57
    exactly um right and if all I can tell
  • 00:47:59
    you is well we've got data from York
  • 00:48:01
    County for the last uh month that's not
  • 00:48:06
    good enough and so what we're trying to
  • 00:48:07
    do is really increase our ability to
  • 00:48:09
    collect data which means having
  • 00:48:11
    volunteer observation programs it means
  • 00:48:13
    using sophisticated new technologies I
  • 00:48:15
    talked about our Radars our Radars we
  • 00:48:18
    have 122 Radars around the country uh
  • 00:48:21
    and these Radars are many decades old
  • 00:48:25
    and there's some new technology out
  • 00:48:27
    there things like phased array radar
  • 00:48:28
    that we might be able to use to get the
  • 00:48:31
    sort of higher resolution observations
  • 00:48:33
    it sounds to me like
  • 00:48:35
    NOA might need a bigger
  • 00:48:38
    budget I'm just saying we're flying
  • 00:48:41
    around in 50 year old prop planes okay
  • 00:48:44
    we got sensors that are old and 20 years
  • 00:48:48
    old 20 years old like we need like come
  • 00:48:51
    on Congress Let's Make It Rain On Noah
  • 00:48:55
    20 years ago there were no smartphones
  • 00:48:57
    and YouTube didn't exist so terms of
  • 00:49:00
    where we are we do I mean if you look at
  • 00:49:03
    the full no Mission it's really pretty
  • 00:49:04
    incredible we've been talking mostly
  • 00:49:06
    about weather here space weather
  • 00:49:07
    atmospheric weather but we also make all
  • 00:49:09
    the the nautical charts you know if
  • 00:49:11
    you're a boater and you want the chart
  • 00:49:13
    you want to know how deep the water is
  • 00:49:14
    and where the shallow areas we do that
  • 00:49:16
