- 00:00:00we all care about the weather and nobody
- 00:00:01wants to to have the weather get the
- 00:00:04best of them one of the most devastating
- 00:00:05aspects of hurricanes is storm surge you
- 00:00:07look at what hurricane Helen just a few
- 00:00:09weeks ago did it was a massive hurricane
- 00:00:11it was 500 mil across I can give you the
- 00:00:14best forecast in the world I can give
- 00:00:16you plenty of lead time but it's your
- 00:00:18decision to evacuate and we can't
- 00:00:21control that and will we need a category
- 00:00:23six because these category fives keep
- 00:00:26getting bigger and bigger but it's a
- 00:00:27storm we've never seen before when are
- 00:00:29we getting to category
- 00:00:31[Music]
- 00:00:35six this is Star Talk Neil degrass Tyson
- 00:00:39your personal astrophysicist got with me
- 00:00:42Chuck nice Chucky baby how you doing hey
- 00:00:44Neil So Chuck today's topic is the
- 00:00:47weather ah excellent yes that's supposed
- 00:00:51to be the safest thing to talk about
- 00:00:53with anyone right no no longer oh no I
- 00:00:57guess not very good point no longer very
- 00:01:00good point well we know that it's
- 00:01:02extreme and if we comb the Earth to find
- 00:01:05who's the top weather person that's
- 00:01:08gonna be Sam Champion WABC news he's
- 00:01:13amazing it's it's gonna yeah every every
- 00:01:16local news has their person who they are
- 00:01:18certain is like the best weather
- 00:01:20forecaster there is but we can go above
- 00:01:22the mall because we're star and we have
- 00:01:24access and we brought in the
- 00:01:28chief chief head honcho of Noah the
- 00:01:32National Oceanic and Atmospheric
- 00:01:34Administration Dr Richard spinrad oh my
- 00:01:38gosh Rick how you doing man hey I'm
- 00:01:40doing great Neil Chuck delighted to be
- 00:01:42here thanks let me get your full title
- 00:01:45straight here the under Secretary of
- 00:01:48Commerce for oceans and atmosphere and
- 00:01:51that's a different title from being Noah
- 00:01:53administrator is that right yeah
- 00:01:55actually my full title will probably
- 00:01:57take the full duration of this show but
- 00:01:59it is the under Secretary of Commerce
- 00:02:01Roan and atmosphere and the
- 00:02:03administrator of Noah the National
- 00:02:05Oceanic and Atmospheric Administration
- 00:02:07so it's really two hats in this job and
- 00:02:10we're reminded that Commerce which is a
- 00:02:12huge branch of the US government cares
- 00:02:14about climate and weather and because
- 00:02:17goods and services are delivered through
- 00:02:19the air on the waters over the land and
- 00:02:23our relationship with climate is deeply
- 00:02:26impacted yeah like Commerce and um the
- 00:02:31melting uh ice that is causing Passage
- 00:02:35through uh a near Alaska and where
- 00:02:40there's it's a contested Waters now
- 00:02:42because you have Russia who wants that
- 00:02:44water uh and we of course and China and
- 00:02:49it's all because it was ice and nobody's
- 00:02:53looking at the point that it was
- 00:02:57Ice what was once ice is now open Waters
- 00:02:59it's now water right yeah yeah that's so
- 00:03:03so so tell me a couple of things here uh
- 00:03:06what is your relationship with the Navy
- 00:03:07because obviously they care about oceans
- 00:03:09as well yeah so that's a great question
- 00:03:11because I actually worked for the Navy
- 00:03:13for the first part of my professional
- 00:03:14career and I was is there any part of
- 00:03:16the government you don't work
- 00:03:18for yeah Congress I have not worked for
- 00:03:21congress yet and that probably won't
- 00:03:22happen either uh but Navy I mean
- 00:03:25obviously Navy cares about uh oceans and
- 00:03:28climate and atmosph here uh and it's not
- 00:03:31just how they operate their ships
- 00:03:32they're going to be concerned about what
- 00:03:34the impacts of climate are going to be
- 00:03:36for their their bases you know you think
- 00:03:38about norfol where we've got the
- 00:03:39Atlantic Fleet and sea level rise
- 00:03:41impacting the operations uh at the base
- 00:03:44there it's an important element of Naval
- 00:03:46operations and North Virginia yeah north
- 00:03:49of Virginia yeah but I could say the
- 00:03:50same thing about just any just about
- 00:03:52anywhere the Navy operates they do care
- 00:03:54about the Shor side facilities uh but
- 00:03:56they also care about the ability to fly
- 00:03:59uh and carry out their missions and
- 00:04:01obviously I mean one of the strongest
- 00:04:03components for Navy is understanding how
- 00:04:05the ocean uh changes what are the
- 00:04:07Dynamics of the ocean how does that
- 00:04:08affect ships and submarines right and
- 00:04:11also uh last I checked there's several
- 00:04:14whole countries in the in the South
- 00:04:17Pacific where the average sea level is
- 00:04:20just only a few feet the aage elevation
- 00:04:23of the land is only a few feet above sea
- 00:04:25level so if we start melting out
- 00:04:27glaciers we'll lose entire countries
- 00:04:29creating is what do they call it climate
- 00:04:31refugees this exactly exactly and and
- 00:04:35this is not some sort of theoretical
- 00:04:36thing that'll happen a thousand years
- 00:04:38from now the sea level rise uh rate that
- 00:04:41you're alluding to has increased
- 00:04:42dramatically when I when I was a grad
- 00:04:45student you know few decades back we
- 00:04:47would talk about sea level rises being
- 00:04:49say 1 to three millimeters per year in
- 00:04:51some places it's doubled or tripled and
- 00:04:54so consequently some of these nations
- 00:04:56are actually going to be eliminated
- 00:04:59before the end of this Century they'll
- 00:05:00actually be underwater right yeah whole
- 00:05:04islands whole island nations that will
- 00:05:06disappear whole island nations and I
- 00:05:10tell me of course everyone cares about
- 00:05:13the weather although climate change has
- 00:05:15been politicized as we all know recently
- 00:05:18i' I'd like to remind people that Noah
- 00:05:21was founded in the year uh
- 00:05:241970 and it was signed into law by a
- 00:05:26Republican president so the
- 00:05:29politicization
- 00:05:30of climate um to me feels like a very
- 00:05:33recent phenomenon because clearly we all
- 00:05:36care about the weather and nobody wants
- 00:05:38to to have the weather get the best of
- 00:05:40them in any part of their life or or or
- 00:05:43job yeah I think the the a lot of the uh
- 00:05:46making it a political issue comes from
- 00:05:48trying to figure out who's whose fault
- 00:05:50this is you know who do we get to blame
- 00:05:52for this the the thing about Noah is
- 00:05:55that our mission is very much looking to
- 00:05:57the Future we're about predictions and
- 00:05:58projections and so for us it's less
- 00:06:01about hey who caused this problem and
- 00:06:03more about how well can we predict what
- 00:06:06the change is going to be in the future
- 00:06:08we talk about that's what people hold
- 00:06:10you to because they're trying to make
- 00:06:11decisions based on your predictions
- 00:06:13however you you have a moving goalpost
- 00:06:15at all times Rick because quite frankly
- 00:06:18what happens is um these projections are
- 00:06:23modled on what we have now okay but the
- 00:06:28variable is is um do we increase the
- 00:06:33amount of fossil fuel that we're burning
- 00:06:36because I mean that's really the issue
- 00:06:38so as you have fossil fuel burning
- 00:06:41coming online that changes everything
- 00:06:43that you guys said was going to happen
- 00:06:46for instance um the predictions that
- 00:06:48were made previous to now um basically
- 00:06:54everybody's like oh yeah well they're
- 00:06:55all wrong but first they were saying
- 00:06:57they're going to be wrong because it's
- 00:06:58not going to happen now they're saying
- 00:07:00wrong because it's happening much
- 00:07:03quicker yeah model would normally have a
- 00:07:07future expectation for a rate of CO2
- 00:07:11increase or a rate of anything isn't
- 00:07:12that right uh Rick yeah that's right and
- 00:07:15and this is what climate scientists
- 00:07:17would call the Assumption of
- 00:07:19stationarity that is to say that things
- 00:07:21now are what they're going to be in the
- 00:07:22future and it's not and that's the whole
- 00:07:25point is so how do you take the models
- 00:07:27that you were talking about Neil and uh
- 00:07:30initialize them put the data in up front
- 00:07:33to start the model what assumptions do
- 00:07:35you make about how those conditions are
- 00:07:37going to change in a year in 10 years in
- 00:07:4020 years that's the challenge we have in
- 00:07:43front of us but we're getting really
- 00:07:44good and improving the skill on those
- 00:07:47models now Rick have you has your scope
- 00:07:50been uh I'm wondering
- 00:07:52it I think when Noah was founded by the
- 00:07:56way I I did a deep dive into this
- 00:08:00hardly anyone certainly not even
- 00:08:02geologists or biologists had ever
- 00:08:05combined ocean and Air in the same sort
- 00:08:10of conversation there were atmospheric
- 00:08:13scientists there were Oceanic scientists
- 00:08:16and the full system the full the full um
- 00:08:20organic system of all these interplaying
- 00:08:23parts it seemed to me only came of age a
- 00:08:26little later when uh computer models
- 00:08:29started having something to say about it
- 00:08:31and so now I what I what I POs to you is
- 00:08:35now what's under Noah purview is also
- 00:08:39space weather like what the sun is doing
- 00:08:42so these these look like land grabs to
- 00:08:44me we're
- 00:08:46spacecraft you started out with just the
- 00:08:48ocean in there now you want like the
- 00:08:51solar system the universe we're going
- 00:08:53for the universe going for yeah Neil
- 00:08:55you're exactly right and it is an earth
- 00:08:58system and the best place to see that is
- 00:09:01in how hurricanes form and grow and move
- 00:09:05you can't predict that without a good
- 00:09:08understanding of the ocean and the
- 00:09:09atmosphere and you know the best example
- 00:09:12on that one was uh Hurricane Katrina
- 00:09:14which as you may remember intensified
- 00:09:17really quickly before it made landfall
- 00:09:19around New Orleans and we now looking
- 00:09:22back no we could have predicted that
- 00:09:24better if we'd had better data from the
- 00:09:27ocean in the Gulf of Mexico
- 00:09:30happen today you would have predicted it
- 00:09:32better than we were able to do back in
- 00:09:342005 yeah certainly the what we call the
- 00:09:36rapid intensification of the hurricane
- 00:09:39as it made landfall and that's because
- 00:09:41we would look at the whole ocean not
- 00:09:43just the surface of the ocean to put the
- 00:09:45data yeah you guys you guys I mean
- 00:09:48you're not you're being humble Because
- 00:09:50You're Not tooting your own horn about
- 00:09:52this last uh huge storm that we just
- 00:09:56experienced um where the rapid int
- 00:09:59ification was predicted and did happen
- 00:10:02indeed um uh due primarily to the amount
- 00:10:07of moisture that was being held in the
- 00:10:09land mass uh where the storm was uh
- 00:10:12going to Traverse so you know you should
- 00:10:15you should say yeah we didn't do it back
- 00:10:17in 2005 but take this we did it
- 00:10:20now I'm sorry I don't think I don't
- 00:10:22think he speaks that way
- 00:10:23Chu I love the way you said that though
- 00:10:25Chuck because right I that was Rick
- 00:10:28catch us up on on this thing with land
- 00:10:30water and how that is not neutral as as
- 00:10:35a
- 00:10:36forcing as a forcing factor on a
- 00:10:38hurricane that makes landfall what I
- 00:10:40understood there was a recent hurricane
- 00:10:42that saturated the landscape the the
- 00:10:45land and so now when a hurricane makes
- 00:10:48landfall there is sort of latent heat
- 00:10:51available to it from the water that is
- 00:10:56in the saturated ground or because
- 00:10:58normally hurricane would would weaken as
- 00:11:01it goes over the land right yeah it's
- 00:11:03all about temperatures right and so we
- 00:11:05know the temperatures of the ocean in
- 00:11:07this case the Gulf of Mexico are going
- 00:11:08up know the temperatures in the
- 00:11:10atmosphere are going up which means that
- 00:11:12those storms can hold more water and so
- 00:11:15think about it we had hurricane Harvey
- 00:11:17that hit Houston and it dropped five
- 00:11:21feet five feet of rain when I was a kid
- 00:11:24we didn't talk about feet of rain from
- 00:11:27and so now you look at what hurricane
- 00:11:29Helen just a few weeks ago did
- 00:11:31especially in Western North Carolina and
- 00:11:33the damage was water you're absolutely
- 00:11:35right most people think hurricane so
- 00:11:36it's about winds wind in that case it
- 00:11:38was water but in terms of the forcing
- 00:11:41function on the hurricane itself that
- 00:11:44water that's sort of still had had had
- 00:11:47rendered land masses uh soaked are you
- 00:11:51saying that that does not continue to
- 00:11:53play into the other than the water's got
- 00:11:56nowhere else to go I guess you just get
- 00:11:58yeah well that's basically it it it I
- 00:12:01think it's a combination if you've got
- 00:12:02if you've got soaked uh uh terrain from
- 00:12:07previous precipitation prior to the
- 00:12:09hurricane coming in and that Hurricane's
- 00:12:11got more moisture than it would have
- 00:12:12before Helen was also huge it was a
- 00:12:15massive hurricane it was 500 miles
- 00:12:19across uh and that's that's
- 00:12:22significantly larger than most
- 00:12:23hurricanes so large hurricane warm
- 00:12:26Waters so more moisture available the
- 00:12:28ground was already pretty wet and now
- 00:12:30you're just dumping buckets onto a wet
- 00:12:32sponge so it's going to cause a lot of
- 00:12:34flooding why do I have in my notes that
- 00:12:35you also care about the bottom of the
- 00:12:37ocean like what what what what does that
- 00:12:40do for you well there's a hole in the
- 00:12:42bottom of the
- 00:12:44ocean no there's a plug oh that's right
- 00:12:47yeah yeah the bottom of the ocean is
- 00:12:49important because without a bottom of
- 00:12:50the ocean we wouldn't have an ocean I
- 00:12:52guess okay more important I mean so the
- 00:12:55Topography of the ocean is going to
- 00:12:57drive help Drive uh how the currents uh
- 00:13:00especially in coastal environments where
- 00:13:02the water goes how it flows uh it's
- 00:13:04going to impact things like uh
- 00:13:07accentuated tides in areas where you've
- 00:13:09got extreme changes in topography so why
- 00:13:12is this important especially in the
- 00:13:13context of a hurricane probably one of
- 00:13:16the biggest problems one of the most
- 00:13:17devastating aspects of hurricanes is
- 00:13:19storm surge what happens to the water
- 00:13:23the ocean water when it gets close to
- 00:13:25the shore if the Topography is just
- 00:13:28right you can actually funnel that storm
- 00:13:30surge and you can end up with 12 to 15
- 00:13:34feet that's what they got in Tampa Bay
- 00:13:35when uh hurricane Milton hit yeah and
- 00:13:37and Hurricane Sandy hit New York I mean
- 00:13:40I think it was tropical storm Sandy at
- 00:13:42the point it hit New York but that storm
- 00:13:44surge is what took us out it we actually
- 00:13:46call it superstorm Sandy because it was
- 00:13:48both a tropical cyclone and then there
- 00:13:49was an nor Easter component to it as
- 00:13:51well so it was kind of like the worst of
- 00:13:53all factors combined and yeah you're
- 00:13:55right storm surge yeah I you know I grew
- 00:13:58up in New York and mom was living in an
- 00:14:00apartment that got flooded as a result
- 00:14:01of superstorm sanding uh and we did not
- 00:14:04that's interesting that was what 12
- 00:14:05years ago we didn't have the forecast
- 00:14:07down pat
- 00:14:19yet you know having a front row seat to
- 00:14:22Neil's life over the years and also
- 00:14:24being a parent myself I absolutely love
- 00:14:26that quote as parents there's no greater
- 00:14:29gift we can give to our kids than the
- 00:14:31freedom of curiosity and an eagerness to
- 00:14:34always be learning and that's why we
- 00:14:37here at Star Talk are honored to have

- 00:15:56let's get back to the show so when did
- 00:15:58you start reaching out and caring about
- 00:16:00what the sun
- 00:16:01does um well we've always had that as
- 00:16:04part of our mission I think it's fair to
- 00:16:07say that I mean obviously the sun has a
- 00:16:09luminosity and an energy but but but it
- 00:16:13at the next level the sun cycles and
- 00:16:15there solar storms and so it's not just
- 00:16:18that there's a star there delivering
- 00:16:19energy to your model there are these
- 00:16:21fluctuations in the energy to the model
- 00:16:23that now you guys seem to car about yeah
- 00:16:26so the the the Sun is a pretty Dynamic
- 00:16:30uh object and uh it goes through these
- 00:16:33Cycles right and we're actually in the
- 00:16:36middle of one of these 11year Cycles it
- 00:16:37started last year and one of the really
- 00:16:40interesting aspects of that is that the
- 00:16:42sun can occasionally actually send out
- 00:16:46these huge huge coronal mass injections
- 00:16:50which are these charged gases plasmas
- 00:16:52that get ejected from the surface of the
- 00:16:55Sun at a speed of about 1 to 2 million
- 00:16:57miles hour uh they are on the sort of
- 00:17:01positive side the the factors that
- 00:17:02create the beautiful Northern Lights the
- 00:17:04Aurora Borealis but a little bit more
- 00:17:06insidiously they also interact with
- 00:17:08navigation systems they interact with
- 00:17:11electrical grids uh they can affect uh
- 00:17:15Power grids uh they can affect uh
- 00:17:18communication systems and so in fact the
- 00:17:21storm that uh erupted in last May May of
- 00:17:252024 solar storm solar storm the solar
- 00:17:27storm was category what we call G5
- 00:17:30geomagnetic storm 5 highest uh rank
- 00:17:33storm one of the most severe that we've
- 00:17:35seen in decades but you didn't hear
- 00:17:38about it much well I know you did Neil
- 00:17:40but a lot hear about it and and that's
- 00:17:43because we knew it was coming and in
- 00:17:46years past we might not have known it
- 00:17:48was coming and so we could make change
- 00:17:51what kind of changes airplanes could
- 00:17:53change their their roots in order to
- 00:17:55avoid the impact of the solar storm on
- 00:17:58their GPS systems can you see the actual
- 00:18:01discharge as it makes its way here that
- 00:18:04is so cool yes you can and in fact we
- 00:18:07have just launched uh in June of 2024 we
- 00:18:11launched a new satellite it's a weather
- 00:18:13satellite it's the one that you would
- 00:18:15use when you turn on TV and they show
- 00:18:17you the full disc of what the weather
- 00:18:19patterns are in the East Coast or West
- 00:18:20Coast but this one has a compact
- 00:18:24coronagraph oh and that is the tool I'm
- 00:18:28sorry I you guys lost me Neil said oh
- 00:18:30nice you said you said compact
- 00:18:33coronograph like uh you know like I say
- 00:18:36uh my glasses case it's just like my
- 00:18:39glasses case and I'm like okay what is a
- 00:18:41compact coronagraph I got this so one of
- 00:18:44the great inventions of of the recent
- 00:18:47Century has been the ability to create
- 00:18:50an image of the Sun in a telescope as
- 00:18:53though with a set of Optics as though
- 00:18:56the sun had just been eclipsed by the
- 00:18:59moon oh and when the sun gets eclipsed
- 00:19:01by the moon all the bright stuff is
- 00:19:03blotted out and you see the edge you see
- 00:19:05explosions on the edge right you
- 00:19:07remember when we saw the eclipse this
- 00:19:10recent Eclipse when we were stationed up
- 00:19:13in in Vermont uh you saw these along the
- 00:19:17edge there were these little sort of
- 00:19:18prominences sticking out so imagine
- 00:19:20being able to do that at will right
- 00:19:22rather than waiting around for an
- 00:19:24eclipse and so now Rick you say you put
- 00:19:27one of these in orbit that's cool Yeah
- 00:19:29we actually have that one in orbit there
- 00:19:30is another sensor on the Discover
- 00:19:32satellite which is at the L1 the lrange
- 00:19:35one point um the Earth Sun lrange yes
- 00:19:40exactly okay now Chuck don't we have a
- 00:19:42lrange explainer we do for those of you
- 00:19:45who want to uh really go a deep dive on
- 00:19:48lrange points uh we go all all through
- 00:19:51all l12 34 and it's uh really incredible
- 00:19:56um M5 can't leave out M5 uh
- 00:20:00um clearly I was only a pay attention
- 00:20:02for
- 00:20:05four five's important because we're
- 00:20:08really
- 00:20:09good years all gr points are not made
- 00:20:12equal right but if you want to see how
- 00:20:15you can find perfect equilibrium in the
- 00:20:17solar system uh to me that's what lrange
- 00:20:20point represents I love exactly exactly
- 00:20:22so it depends on which two bodies around
- 00:20:25which you're describing the lrange
- 00:20:26points so so Rick this is the Earth Sun
- 00:20:28lrange points is that correct yeah and
- 00:20:31and as you can well describe by having
- 00:20:34multiple views of the Sun from different
- 00:20:37angles that is to say in Earth orbit and
- 00:20:39then at L1 and at L5 we can look at
- 00:20:42basically the whole threedimensional
- 00:20:44character of the sun because not all of
- 00:20:47these coronal mass ejections are
- 00:20:48necessarily aimed at us so we need we we
- 00:20:52care about them all but at Noah We Care
- 00:20:55mostly about the ones that are going to
- 00:20:56be aimed at us and again do the math
- 00:20:59these things travel in about 1 to two
- 00:21:01million miles per hour Sun's 93 million
- 00:21:05miles away so it's a you know a three to
- 00:21:08four day transit that we can give people
- 00:21:10enough lead time to make preparations
- 00:21:12for a major geomagnetic storm so we can
- 00:21:15imagine a future where we have a colony
- 00:21:16on the moon or Mars uh where those
- 00:21:19neither of those objects have shielding
- 00:21:22from this kind of radiation in the way
- 00:21:24we pretty much do here on Earth with our
- 00:21:27atmosphere and our ozone but they don't
- 00:21:29so presumably they would be deeply
- 00:21:32connected Into Your Capacity to
- 00:21:36predict because then everyone would know
- 00:21:37to run underground or run behind
- 00:21:39shelters this sort of thing so so can I
- 00:21:42ask okay this might be a silly question
- 00:21:43but I'm just asking um so with all your
- 00:21:46equipment because Noah is really a space
- 00:21:50organization I mean you're looking back
- 00:21:52at Earth but all your stuff's up in the
- 00:21:55space no no they got buoys and stuff
- 00:21:58that's true that's true I take it back I
- 00:22:00take it back okay you're absolutely
- 00:22:02right um but when you when you talk
- 00:22:05about these ejections do you move that
- 00:22:09stuff or is that stuff just hardened or
- 00:22:11what do you because I mean radiations
- 00:22:14has got to be like the most damaging
- 00:22:15thing for equipment right yeah you're
- 00:22:18not going to be able to move this I mean
- 00:22:19this is immense amounts of energy but
- 00:22:21what you can do is it's it actually it's
- 00:22:23really similar to our discussion on
- 00:22:25hurricanes we're not going to be able to
- 00:22:27move hurricanes and spite of what some
- 00:22:29people may think but we can make the
- 00:22:31predictions work and we can tell people
- 00:22:34this one's bearing down here on Tampa
- 00:22:36plus or minus 20 miles and you got two
- 00:22:39days to evacuate same thing with space
- 00:22:42weather if we get the picture especially
- 00:22:44if you've got multiple views we can say
- 00:22:47this is going to hit pretty hard in the
- 00:22:49northern part of Quebec or in Asia and
- 00:22:53therefore folks can make adjustments
- 00:22:55they have three days they can power down
- 00:22:58their grids they're electrical grids
- 00:23:00they can revor aircraft so they're not
- 00:23:02going to be affected for navigation
- 00:23:04purposes Chuck asked about the the
- 00:23:06satellites that are already in orbit
- 00:23:08they certainly have susceptibility to
- 00:23:09this and you can't just say hey Bank a
- 00:23:11left or hover over Africa until it's
- 00:23:14clear over Asia right you can't do that
- 00:23:16you can't uh we can Shield some of these
- 00:23:19to a certain extent but what we can do
- 00:23:21is again if we know it's coming we can
- 00:23:23make accommodations with regard to power
- 00:23:25or use another satellite uh to cover for
- 00:23:28the one that most be mo might be most
- 00:23:30vulnerable the sacrifice
- 00:23:33satellite yeah no we don't do that we
- 00:23:35don't put them
- 00:23:37up so there's something called
- 00:23:39unexpected events now I foresee the day
- 00:23:42where no event is unexpected and so no
- 00:23:46one is taken by surprise where are we
- 00:23:48now with regard to Noah's modeling and
- 00:23:51other agencies modeling and things just
- 00:23:54happening taking Everyone by surprise
- 00:23:56there's a really interesting aspect to
- 00:23:58your your question Neil because um
- 00:24:01there's a there's a famous story in
- 00:24:03meteorology it's called Isaac storm in
- 00:24:05fact Eric Larson wrote a great book on
- 00:24:07Isaac storm and it was a hurricane that
- 00:24:09hit galvaston in the year 1900 for the
- 00:24:12folks in galvaston in 1900 that storm
- 00:24:14was an unexpected storm they didn't
- 00:24:16expect it to hit now obviously there's
- 00:24:18never going to be another Isaac storm
- 00:24:20we've improved that there are things
- 00:24:22though that happen uh on much shorter
- 00:24:26time scales and so I would say
- 00:24:29they may not be unexpected like
- 00:24:31tornadoes U but the time that we're able
- 00:24:34to give people to react to them and is
- 00:24:37shorter so right now for tornadoes we're
- 00:24:40looking at an average lead time on most
- 00:24:42tornadoes of about 12 minutes whoa about
- 00:24:4650 years ago the lead time on tornadoes
- 00:24:50was minus five
- 00:24:52minutes okay that doesn't even make any
- 00:24:55sense I'm just saying when the tornadoes
- 00:24:58over I already know there was a tornado
- 00:25:01that's right that's right yeah there is
- 00:25:05something wrong with that picture um
- 00:25:07wait just just to clarify you're not
- 00:25:08talking about the prediction of the
- 00:25:11existence of a tornado you're talking
- 00:25:12about the path a tornado will take once
- 00:25:14it forms yeah yeah the path it's going
- 00:25:16to take and how intense it's going to be
- 00:25:18gotcha yeah and because there are like
- 00:25:21like with hurricanes tornadoes have
- 00:25:22classifications by intensity we have the
- 00:25:25extended fueta scale for tornadoes one
- 00:25:27through five uh and it's the same kind
- 00:25:29of thing so right now we can say we
- 00:25:32think this tornado or this uh this
- 00:25:36aggregation of tornadoes is going to
- 00:25:38take this path and it's probably going
- 00:25:39to be an ef2 and it's probably going to
- 00:25:41hit over here in 15 minutes by the way
- 00:25:4412 minutes 15 minutes is enough time to
- 00:25:47get out of the way of a tornado or or to
- 00:25:49go or underground yeah underground yeah
- 00:25:52so that's an that's incredible how do
- 00:25:55you feel I mean do we have deep resonant
- 00:25:59emotions uh when for example you go to
- 00:26:02see a a movie that you know stormchasers
- 00:26:06movie you know yeah Twisters Twisters
- 00:26:10how how do you let's commiserate
- 00:26:12together here now uh how do you feel
- 00:26:15when you see these films how how much
- 00:26:16effort do they call you and say help us
- 00:26:18get this right or they just make stuff
- 00:26:20up and and and and is it true that in a
- 00:26:22tornado I can actually call a cow as it
- 00:26:26comes by and it goes
- 00:26:29and then
- 00:26:31disappears of course Chuck that's a
- 00:26:33stupid question everybody knows
- 00:26:36that uh we are not using bow Vine
- 00:26:38sensors and tornadoes uh for our
- 00:26:41forecast systems yet
- 00:26:43so the cow could just totally hook you
- 00:26:46up on
- 00:26:47that what is your if mind if I ask what
- 00:26:50is Noah's annual budget uh it's just
- 00:26:52under s billion would you say that
- 00:26:55Noah's effort saves people and lives and
- 00:27:00on a level far beyond the value of that
- 00:27:02budget well I I mean we talk about
- 00:27:05answer is yes Rick you're the head of
- 00:27:06the
- 00:27:07organization for Christ's sake man NE
- 00:27:11answer is yes right thank you
- 00:27:13Rick the uh we talk about lives and
- 00:27:16livelihoods and and Lifestyles so
- 00:27:18property and lives um but certainly
- 00:27:20lives and the only reason I HED is
- 00:27:23because I can give you the best forecast
- 00:27:25in the world I can give you plenty of
- 00:27:27lead time
- 00:27:28but it's your decision to evacuate it's
- 00:27:31your decision to take action and we
- 00:27:34can't control that so we like to think
- 00:27:37that two things one the quality of our
- 00:27:39forecast is getting better and the
- 00:27:40second is the trust by the public in
- 00:27:43that forecast uh and the on onscreen
- 00:27:46meteorologists and emergency managers is
- 00:27:49high enough so that when we say you
- 00:27:51better Evacuate the storm is coming your
- 00:27:53way people actually take that action but
- 00:27:55there's no question I mean I talked to
- 00:27:56you about the the storm in galston in
- 00:27:59the year um 1900 and I think the number
- 00:28:03was something like 10,000 lives were
- 00:28:05lost in that storm wow my that's not
- 00:28:07ever going to happen again in this
- 00:28:09country ever and that's because of the
- 00:28:12quality of the forecast and our ability
- 00:28:14to have the trusted people to make these
- 00:28:16decisions so yeah absolutely we're
- 00:28:17saving and you also affect uh forecast
- 00:28:20for Fisheries right and other sort of
- 00:28:23coastal management of marine food is
- 00:28:27that a so we do Marine forecasts as part
- 00:28:30of what the weather service does and we
- 00:28:32also have responsibility for managing
- 00:28:34marine fisheries uh which means we're
- 00:28:36the ones who do the stock assessments of
- 00:28:39how many fish are out there how healthy
- 00:28:42are the fish how healthy are the
- 00:28:43populations and establish regulations
- 00:28:46for how to sustainably fish for these uh
- 00:28:52uh these fish and maintain a strong
- 00:28:53Seafood economy again we're part of the
- 00:28:55Department of Commerce so it's an
- 00:28:56important economic consideration so with
- 00:28:59respect to what you just said uh what's
- 00:29:02your relationship with other countries I
- 00:29:04know we're a National Organization but
- 00:29:06do you have international affiliations
- 00:29:08like for the typhoon that's raging in
- 00:29:11Taiwan right now or when it comes to
- 00:29:13sustain sustainability of food supply
- 00:29:15like working with China who just doesn't
- 00:29:17give a damn
- 00:29:20so but but what what's your role there
- 00:29:22we we care about our Coastline and our
- 00:29:24and our uh our Oceanic uh prop Oceanic
- 00:29:29property line if you will but if you're
- 00:29:31studying the entire Earth with regard to
- 00:29:33climate do you share your data with
- 00:29:35other countries and are they responsive
- 00:29:37and what's your relationship yeah yeah
- 00:29:40we absolutely can't do our job without
- 00:29:42strong International collaboration and
- 00:29:44that takes a couple of different forms
- 00:29:45there are worldwide organizations as the
- 00:29:48World Meteorological organization of
- 00:29:50which we are a member and in fact the
- 00:29:52head of our national weather service is
- 00:29:54the US Representative to the wo uh and
- 00:29:57it's these are organizations that
- 00:29:59establish uh policies with regard to
- 00:30:01data and yeah all of our Noah data is
- 00:30:04publicly available uh and we use that as
- 00:30:07if you will lever to say to other
- 00:30:09nations hey we're giving you ours why
- 00:30:11don't you give us yours as well so
- 00:30:13there's a lot of collaboration for data
- 00:30:15and they recognize they need our data to
- 00:30:18improve their forecast we need they
- 00:30:20their data to improve our forecast and
- 00:30:22when you start talking about Fisheries
- 00:30:23yeah there's a lot of international
- 00:30:24agreements because a lot of the fish are
- 00:30:27in open ocean Waters and there have to
- 00:30:28be
- 00:30:29agreements and and the Agreements are
- 00:30:31not just about hey how much fish can we
- 00:30:34take sustainably that is to say to allow
- 00:30:37the population of the fish to stay stay
- 00:30:39uh uh healthy but also to try to um be
- 00:30:45the Protectors of those uh Fisheries by
- 00:30:50um enforcing laws against illegal
- 00:30:52unreported and unregulated Fisheries
- 00:30:55what we call iuu fishing uh so that Rees
- 00:30:58a lot of international cooperation
- 00:30:59because you know what it's a big big
- 00:31:01ocean you know it's not the same thing
- 00:31:04but it's it's similar in some ways the
- 00:31:07Artemis Accord which has recently been
- 00:31:09signed by upwards of 30 countries or so
- 00:31:12is a it's a new agreement about conduct
- 00:31:15in space and space exploration signed by
- 00:31:18space fairing Nations it's an active
- 00:31:21Accord that's going on right now and so
- 00:31:24for example if you send a Rover to the
- 00:31:26moon or Mars and you learn something
- 00:31:28about it you would share that with other
- 00:31:30countries so if they send a Rover they
- 00:31:32don't have to make the same mistakes you
- 00:31:34did or that you can collaborate so uh
- 00:31:37it's interesting how the
- 00:31:38internationality of what you do uh
- 00:31:41certainly uh would would contain tap
- 00:31:44rots for doing things cooperatively in
- 00:31:46space there there's yeah and I think
- 00:31:49there's a lot of commonality there and
- 00:31:51the I thought that was going through
- 00:31:52your mind my mind as you were talking
- 00:31:54about the emis Accords Neil is that we
- 00:31:58to have similar kind of agreements for
- 00:31:59making observations in the ocean there's
- 00:32:03no one nation that can cover all of the
- 00:32:04ocean and so uh we have a a major
- 00:32:07program it's called Argo and it's
- 00:32:08basically these uh robots that go
- 00:32:11throughout the ocean and they go up and
- 00:32:13down and all over and they drift around
- 00:32:15and we by International agreement have
- 00:32:18said let's all agree to what these
- 00:32:20robots these floats should look like
- 00:32:23let's all build them to these specs
- 00:32:26let's put all of these things out so
- 00:32:28there's about four or 5 thousand of
- 00:32:30these out there now and they've been
- 00:32:31floating around for decades and let's
- 00:32:34all share the data in a common data
- 00:32:36repository these are those buoys that I
- 00:32:38was thinking about is that right these
- 00:32:40actually dive down so they don't spend a
- 00:32:42lot of time at the surface they they
- 00:32:44float around and then they ascend to
- 00:32:47about 1,000 or 2,000 meters depth they
- 00:32:50collect temperature solinity other kind
- 00:32:54of variables are measured they'll drift
- 00:32:57for about 10 days days out of 2,000
- 00:32:59meters then come back to the surface
- 00:33:01transmit their data through satellite
- 00:33:03Communications to a central repository
- 00:33:05and then dive back down again and start
- 00:33:07you know rinse and repeat basically you
- 00:33:08know that's badass I just have to say is
- 00:33:11yeah now you know there are some Nations
- 00:33:13though they probably got a back door
- 00:33:15like if you find oil don't tell anybody
- 00:33:20else hey Star Talk fans I don't know if
- 00:33:23you know this but the audio version of
- 00:33:26the podcast actually posts a week in
- 00:33:29advance of the video version and you can
- 00:33:33get that in Spotify and apple podcast
- 00:33:36and most other podcast Outlets that are
- 00:33:39out there multiple ways to ingest all
- 00:33:43that is Cosmic on Star talk let's take
- 00:33:45up this subject of climate change for
- 00:33:47the moment so we know I is it the is the
- 00:33:52fraction a third so for every x amount
- 00:33:55of CO2 that goes into the atmosphere
- 00:33:57does the ocean uptake about a third of
- 00:33:59that or some fraction of it yeah yeah
- 00:34:02there's a variety of estimates but
- 00:34:04that's that's pretty close maybe even
- 00:34:06closer to a half but definitely a large
- 00:34:08percentage okay so and the that means
- 00:34:10the dissolved CO2 in the ocean is in
- 00:34:14some form of partial pressure
- 00:34:17equilibrium with the CO2 in the air so
- 00:34:20if we were to stop CO2 production or
- 00:34:23even introduce CO2 scrubbers in the
- 00:34:26atmosphere we will do this but then
- 00:34:30there's less CO2 pressing down on the
- 00:34:32ocean and the ocean says I have to make
- 00:34:34this in make equilibrium out of this and
- 00:34:36it'll start releasing and it gives it up
- 00:34:38to the atmosphere gives it up to the
- 00:34:39atmosphere so is it true that we would
- 00:34:43not see the immediate effects for quite
- 00:34:46some time perhaps decades even if we
- 00:34:49stopped all fossil fuel burning today
- 00:34:51the short answer to your question Neil
- 00:34:53is yes people talk about the flywheel in
- 00:34:55the carbon cycle uh you could stop the
- 00:34:59introduction uh interesting you raised
- 00:35:01the question of actually actively
- 00:35:02removing carbon dioxide from the
- 00:35:04atmosphere which would accelerate the
- 00:35:07the diminishment of excess carbon
- 00:35:09dioxide in the atmosphere but it would
- 00:35:11still be yeah you're right decades
- 00:35:13before we would see the ocean responding
- 00:35:15in Kind part of the uh the problem uh
- 00:35:20with the dynamic you described is that
- 00:35:23the increased carbon dioxide dissolution
- 00:35:25in the ocean manifests as ocean
- 00:35:27acidification
- 00:35:28right pH thing going on okay of course
- 00:35:32yeah and so in that case it's not simply
- 00:35:35a matter of it's not like opening up a
- 00:35:37bottle of of of Coca-Cola and having all
- 00:35:40the CO2 uh go back out of the liquid
- 00:35:43into the atmosphere a lot of this CO2
- 00:35:46has become part of the carbon cycle
- 00:35:48within the atmosphere in in including
- 00:35:51with a decrease in PH and increased
- 00:35:54acidification and that's where you see
- 00:35:56the uh complete bleaching of coral reefs
- 00:35:59and the death of of of these coral reefs
- 00:36:02which by the way are their in entire
- 00:36:04ecosystems in themselves yeah yeah
- 00:36:07that's part of it uh in fact the the
- 00:36:10major contribution to Coral bleaching is
- 00:36:12actually the temperature temperature the
- 00:36:13warming of the water but because of the
- 00:36:16chemical makeup of most corals The
- 00:36:19increased acidification uh is very
- 00:36:21erosive gross of vent corls so when
- 00:36:24people talk about terraforming Mars and
- 00:36:25moving there
- 00:36:28I'm sorry that was just an excellent
- 00:36:30segue Earth be uh my rebuttal to that
- 00:36:34it's not rebuttal my comment on it is if
- 00:36:37we have the power of geoengineering to
- 00:36:39turn Mars into Earth then we have the
- 00:36:42power of geoengineering to turn Earth
- 00:36:43back into Earth you wouldn't need Mars
- 00:36:46right yeah to do that and so that's kind
- 00:36:48of how I how I view that so Rick this
- 00:36:51past hurricane season
- 00:36:53the was it just my imagination or were
- 00:36:56there more category lives kicking in
- 00:36:59than usual and if so is that the new
- 00:37:04normal and what what what is the new
- 00:37:06normal right now today I we're recording
- 00:37:10this in October it's like 75 degrees
- 00:37:13outside uh when it says unseasonably
- 00:37:15warm temperatures today will that soon
- 00:37:18become seasonably
- 00:37:20warm that's unseasonable becomes
- 00:37:23seasonable because that's the new normal
- 00:37:26and will we need a category six because
- 00:37:28these category fives keep getting bigger
- 00:37:30and bigger and it keep saying category
- 00:37:32five but it's a storm we've never seen
- 00:37:34before when are we getting to category
- 00:37:36six Chuck stop poking the bear what
- 00:37:39you're doing I love that question Chuck
- 00:37:42and I will get to it in a minute I but
- 00:37:45what I I do want to say is um yeah I
- 00:37:48keep thinking about uh the New York
- 00:37:50Times Colonist Tom Freedman who said
- 00:37:52it's not global warming it's Global
- 00:37:54weirding weirding and you know and if
- 00:37:57think about it Neil we don't talk global
- 00:37:59warming anymore we talk climate change
- 00:38:02and that's because it manifests in so
- 00:38:05many many different ways and and
- 00:38:08fundamentally fundamentally what we're
- 00:38:10doing is we're putting more energy into
- 00:38:11the system because of the greenhouse
- 00:38:14effect there's more energy coming into
- 00:38:16the system so your question about uh
- 00:38:18what's going to be seasonable or not
- 00:38:20seasonable what are the storms look like
- 00:38:22things are going to be different uh this
- 00:38:25year for example we predicted an above
- 00:38:29normal uh hurricane season and it's
- 00:38:32turning out it is above normal by
- 00:38:35certain measures is that going to become
- 00:38:37The New Normal well I think just logic
- 00:38:39suggests that we can probably see a lot
- 00:38:41more hurricane activity in the future in
- 00:38:44terms of the intensity of storms how
- 00:38:45much water they have with them that sort
- 00:38:47of thing which gets to Chuck's comment
- 00:38:50and that is you know my take is it's not
- 00:38:52about do we need another category a
- 00:38:55category six in the saffer Simpson scale
- 00:38:57want you to name it after him a a Chuck
- 00:39:00hurricane is a category six hurricane
- 00:39:02well there's something wrong with
- 00:39:03calling something a nice hurricane
- 00:39:05that's the no not we'll call it not so
- 00:39:07nice not so nice no you leave out his
- 00:39:09last name just called the Chuck
- 00:39:11hurricane the Chuck
- 00:39:12hurricane what we really need in that
- 00:39:15regard is uh to expand the focus because
- 00:39:18you know the the saffer Simpson scale is
- 00:39:20really a measure of of wind right uh how
- 00:39:23strong are the winds and you see that
- 00:39:24every time hey the winds have just
- 00:39:26gotten to 130 M miles an hour so now
- 00:39:28it's a cat war that kind of thing but
- 00:39:31when you look at what these hurricanes
- 00:39:33are doing we're looking at impacts of
- 00:39:35storm surge I talked about the volumes
- 00:39:37of water from hurricanes like like
- 00:39:39Harvey years ago we need people to
- 00:39:41understand that we should be looking at
- 00:39:42more than just what the peak wind is
- 00:39:45because you could have a cat five with
- 00:39:47really strong 170 m hour winds but it
- 00:39:50may not have the impact that a cat 3 has
- 00:39:54with a large volume of water like
- 00:39:56hurricane h
- 00:39:58we find way for people the full me of
- 00:40:01what the hurricanes are what they look
- 00:40:03and what their imps going to be and let
- 00:40:05me toot your horn for a moment here in
- 00:40:07the
- 00:40:081989 sequel to Back to the Future titled
- 00:40:11Back to the Future Part Two uh they went
- 00:40:14into the future the year
- 00:40:172015 and so we're watching this movie in
- 00:40:201989 and they're they are Imagining the
- 00:40:23year 2015 and there's a point where
- 00:40:26Marty and and
- 00:40:28and Doc get out of the car and Doc puts
- 00:40:32up an umbrella and Marty says what are
- 00:40:34you doing he says oh this is the future
- 00:40:37weather forecasting is now we know the
- 00:40:39exact minute it's going to start to rain
- 00:40:41and right in that instant it starts to
- 00:40:42rain and it stops ready stops and then
- 00:40:45it stops and he puts the umbrella away
- 00:40:47we're not exactly there but of course on
- 00:40:50our smartphones it'll show you when the
- 00:40:53rain is going to begin where you are and
- 00:40:54where it's end that's what I'm saying
- 00:40:57that's true I never even thought of that
- 00:40:59but it's it gives you the time of day
- 00:41:01like 3 p.m. starts yeah in your spot and
- 00:41:04and it tells you how much and how
- 00:41:05intense and Chuck when we were growing
- 00:41:07up it was like all you really want to
- 00:41:10know what what might it rain tomorrow
- 00:41:12because you have a and then they give
- 00:41:14you a 50% chance which means they know
- 00:41:16absolutely nothing right your
- 00:41:18grandmother knew more my badis is acting
- 00:41:20up my shoulder I tell you baby it's
- 00:41:23going to rain tomor my shoulder how for
- 00:41:26all you know Noah's got Grandma's in the
- 00:41:27back
- 00:41:28room yeah
- 00:41:30right e how's your knee I tell you I
- 00:41:34tell you it's going to rain and eel
- 00:41:36predicts the Hurricanes
- 00:41:38exactly well you know it's interesting
- 00:41:40because I was gonna say Neil that yeah I
- 00:41:42do have a couple apps on my phone in
- 00:41:44fact and I use it for just that okay you
- 00:41:46know should we have that picnic now or
- 00:41:48should we wait an hour that kind of
- 00:41:50thing and that's less about the
- 00:41:51prediction and more about the
- 00:41:53observations and so the The Radars that
- 00:41:56we've got the satellites have got so
- 00:41:57much resolution right now that you can
- 00:41:59start doing that you can right within an
- 00:42:01hour or two you can say hey this storm I
- 00:42:04mean I use it all the time when I'm when
- 00:42:06I'm walking my dog I'm saying all right
- 00:42:08should I do it now or should I wait an
- 00:42:09hour so you're say you're saying that's
- 00:42:11because we have real-time observation of
- 00:42:13what's exactly exactly yeah yeah and we
- 00:42:16can uh and tornadoes are a really good
- 00:42:19example you know we've gotten really
- 00:42:20good at observing tornadoes using some
- 00:42:23of the new sophisticated applications we
- 00:42:26use something called dual polarization
- 00:42:28on our weather radars which is in the
- 00:42:30old Radars it was basically just send
- 00:42:33out a signal and see what comes back and
- 00:42:35now we can start manipulating the signal
- 00:42:38looking at the polarization of the
- 00:42:39signal to determine uh is that rain is
- 00:42:42it sleet is it snow and get such good
- 00:42:46resolution that we can say yeah it's
- 00:42:49sleet but we know the temperature two
- 00:42:52miles away is warmer and we can see how
- 00:42:54fast it's coming so in an hour it's
- 00:42:57going to be rain over
- 00:42:59here okay so cool man we actually fly
- 00:43:02through the hurricanes and we've been
- 00:43:03doing that for quite a while we have uh
- 00:43:06two actually more than that we have at
- 00:43:09least three airplanes that we use to fly
- 00:43:11through or over the Hurricanes that's
- 00:43:14the right stuff right there want talk
- 00:43:17right stuff man and I've done that once
- 00:43:19I did it once with our team who you got
- 00:43:21piss off to get that
- 00:43:24job but all fair is Rick if I I I some
- 00:43:27of the math on this if you're standing
- 00:43:29there on stationary Earth and 170 mph
- 00:43:32wind is coming by you that that's going
- 00:43:34to Tumble buses and trucks and the cow
- 00:43:37of course will fly by however um an
- 00:43:41airplane in open air flies 500 600 miles
- 00:43:45an hour way faster than the air in a
- 00:43:47hurricane so is it not as dangerous for
- 00:43:51an airplane as you might otherwise think
- 00:43:54yeah I I'm going to be the first to tell
- 00:43:56you it is a d dangerous thing to do but
- 00:43:58our crews are real Aces they are amazing
- 00:44:02professionals and the equipment that we
- 00:44:03fly we actually fly 50-year-old
- 00:44:06airplanes but we're scheduled to buy
- 00:44:08some brand new ones here soon and we fly
- 00:44:11uh Navy p3s the same airplanes that the
- 00:44:14Navy used to use to find submarines and
- 00:44:17here's the kicker that we fly them high
- 00:44:19enough through the hurricane that yeah
- 00:44:21when you go through the eyewall the
- 00:44:23hurricane where there's extraordinary
- 00:44:25vertical uh wind currents you're going
- 00:44:28to go through several thousand feet of
- 00:44:31uh uh elevation change if you did that
- 00:44:34on a commercial flight to Cleveland uh
- 00:44:37you'd have a real problem and you'd be
- 00:44:38sending a complaint to the airline G to
- 00:44:40be a lot of uh vouchers giving out at
- 00:44:43the end of that flight and and we do it
- 00:44:46repeatedly we'll fly we'll do like a a a
- 00:44:49figure four pattern through the
- 00:44:50hurricane two or three times and then
- 00:44:53the other really cool thing though is we
- 00:44:54don't just fly those aircraft through
- 00:44:57the Hurricanes at say 8 10,000 ft we
- 00:45:00also drop drones from the airplanes so
- 00:45:04that they those drones can then fly at
- 00:45:07the lower altitudes and get all the data
- 00:45:09we need so you know when you talked
- 00:45:12about not just Jo writing you're getting
- 00:45:13data at every turn oh we're getting data
- 00:45:16up the Wu real time it's going back to
- 00:45:18the National Hurricane Center they are
- 00:45:19assimilating those data into the
- 00:45:21predictive models and because of those
- 00:45:23flights the track and intensity
- 00:45:25forecasts have improved by 10 15 20% so
- 00:45:29that real-time message to the guy on the
- 00:45:30beach who says I don't know if I should
- 00:45:32evacuate or not uh has gotten so much
- 00:45:34better look at the look at the tracks
- 00:45:36from Hurricane Milton you saw that two
- 00:45:38three days out we were saying it's gonna
- 00:45:39hit Tampa St Pete and we were spot on y
- 00:45:42they were totally tight so Rick as a
- 00:45:45weather phenomena around the world even
- 00:45:48if it's just simply higher temperatures
- 00:45:50than ever before uh whatever is the
- 00:45:53phenomenon that's stretching the limits
- 00:45:57of what might have been models that were
- 00:46:00comfortably contained within certain
- 00:46:02parameters every time there's an
- 00:46:04unprecedented
- 00:46:05event uh that you didn't predict what is
- 00:46:09what do you have to do with your models
- 00:46:11what what's what's the next step here
- 00:46:14yeah that's a a great question
- 00:46:16especially if you kind of extend it and
- 00:46:17say how does something like AI or
- 00:46:20machine learning artificial intelligence
- 00:46:21and machine learning fit in here um and
- 00:46:24these uh extraordinary events and I
- 00:46:27think some of the heat waves we've seen
- 00:46:28some of the droughts we've seen are
- 00:46:30examples uh they end up providing an
- 00:46:34incredible volume of new data and our
- 00:46:37artificial intelligence applications
- 00:46:40depend critically on what we call
- 00:46:42training data so the data from what has
- 00:46:45happened in the past being used as
- 00:46:47training for the models of the future so
- 00:46:50I would argue when we don't fully
- 00:46:54characterize a particular event with our
- 00:46:56forecast
- 00:46:57but we are able to collect all the data
- 00:46:59from that event we are by definition
- 00:47:01improving our ability to use AI
- 00:47:03techniques machine learning techniques
- 00:47:05except by definition your AI That's
- 00:47:07mining the data will not have data that
- 00:47:12it has never seen that is yet to see
- 00:47:14which is the argument for making sure we
- 00:47:17fully measure and characterize these
- 00:47:19extreme events and so a lot of our
- 00:47:22investment at Noah is building the
- 00:47:25systems that provide uh much more
- 00:47:27intense higher temporal resolution in
- 00:47:30the data for things like extreme
- 00:47:33precipitation one of the main things
- 00:47:35we're trying to do right now it's a
- 00:47:36clarify temporal resolution you can
- 00:47:38think of spatial resolution you know how
- 00:47:40much detail do you have from A to B to
- 00:47:42see in location but temporal resolution
- 00:47:45would be what's happening this hour this
- 00:47:47minute this second and so it's a
- 00:47:50resolution over time in case people were
- 00:47:51wondering everybody wants to know what's
- 00:47:53happening in their neighborhood right
- 00:47:54and a lot of
- 00:47:57exactly um right and if all I can tell
- 00:47:59you is well we've got data from York
- 00:48:01County for the last uh month that's not
- 00:48:06good enough and so what we're trying to
- 00:48:07do is really increase our ability to
- 00:48:09collect data which means having
- 00:48:11volunteer observation programs it means
- 00:48:13using sophisticated new technologies I
- 00:48:15talked about our Radars our Radars we
- 00:48:18have 122 Radars around the country uh
- 00:48:21and these Radars are many decades old
- 00:48:25and there's some new technology out
- 00:48:27there things like phased array radar
- 00:48:28that we might be able to use to get the
- 00:48:31sort of higher resolution observations
- 00:48:33it sounds to me like
- 00:48:35NOA might need a bigger
- 00:48:38budget I'm just saying we're flying
- 00:48:41around in 50 year old prop planes okay
- 00:48:44we got sensors that are old and 20 years
- 00:48:48old 20 years old like we need like come
- 00:48:51on Congress Let's Make It Rain On Noah
- 00:48:5520 years ago there were no smartphones
- 00:48:57and YouTube didn't exist so terms of
- 00:49:00where we are we do I mean if you look at
- 00:49:03the full no Mission it's really pretty
- 00:49:04incredible we've been talking mostly
- 00:49:06about weather here space weather
- 00:49:07atmospheric weather but we also make all
- 00:49:09the the nautical charts you know if
- 00:49:11you're a boater and you want the chart
- 00:49:13you want to know how deep the water is
- 00:49:14and where the shallow areas we do that
- 00:49:16we manage Marine protected areas we
- 00:49:19haven't even talked about our fisheries
- 00:49:20management and you know what it costs
- 00:49:22every American for all of these Services
- 00:49:25it costs six cents per day here's what
- 00:49:27we need we need Sarah mlin to sing a
- 00:49:31song to sing the song and then we could
- 00:49:34tell people for only six cents a
- 00:49:38day we can support Noah in a way
- 00:49:44that s
- 00:49:48m right they need a Sarah mclin Worthy
- 00:49:51song yes
- 00:49:52exactly right just let it let it flow
- 00:49:55from nautical charts
- 00:49:57to Aurora
- 00:49:59boreales Noah is in your life and for
- 00:50:03only eight cents a day which is two more
- 00:50:05pennies than what you're paying
- 00:50:09now well Rick thanks for making time for
- 00:50:12us thank you uh you know we last cross
- 00:50:14paths back when we were trying to figure
- 00:50:16out how to see this last Eclipse uh and
- 00:50:20a lot of a lot of folks saw some were
- 00:50:22clouded out but eclipses can happen
- 00:50:24again and we have things called
- 00:50:25airplanes that could take to where the
- 00:50:27next eclipse is you'll have to wait for
- 00:50:28it to come to your farm again but I just
- 00:50:32want to say uh it's been a delight
- 00:50:34having you on here and uh if do you
- 00:50:37think you would uh are you likely to be
- 00:50:39replaced I mean are you a political
- 00:50:41appointee I am a political appointee and
- 00:50:43so I serve with the pleasure of the
- 00:50:45president so I mean I think you're the
- 00:50:47right guy SE several people such as
- 00:50:49there have been several NASA
- 00:50:50administrators that went through
- 00:50:52multiple presidents and multiple parties
- 00:50:55yeah so that was a reminder to me me or
- 00:50:57to us all that certain activities of the
- 00:51:00nation um transcend politics and
- 00:51:04transcend the political leadership
- 00:51:06because they're they're surfing on
- 00:51:09science that is the underpinning of it
- 00:51:11all I know more about science than all
- 00:51:13the
- 00:51:16scientists all right so we gotta go so
- 00:51:19give my regards to your whole agency
- 00:51:21this has been a blast and Chuck it has
- 00:51:24been a pleasure thank you so much Rick
- 00:51:26thanks for being Star Talk we we love
- 00:51:28everything you told us and it gives us
- 00:51:30great hope for the future indeed Chuck
- 00:51:32always good to have you man it is always
- 00:51:34a pleasure all right Neil degrass Tyson
- 00:51:36here you're a personal astrophysicist as
