Time:    
00:00hi so for this talk myself and Michael
00:05we'll be alternating between it to go
00:09through different parts in this talk I
00:11am but it's describing the work that
00:13we've done together just to mention a
00:15little bit of age
00:17what we've done is from 2010 to 2014
00:22where we spent well five years working
00:26looking at the data from weather
00:29balloons which there is launched once to
00:35four times a day around the world in a
00:37beta deterrence stations around the
00:39world and these go up into the
00:41atmosphere and they record temperature
00:43pressure and various stuff and so we
00:46started doing analysis to see what's
00:48happening in the atmosphere it is a data
00:51going back to the 50s and we found a
00:53load of different results and we
00:56realized that there was a lot of
00:58paradigms in current atmospheric
01:01modeling that people had never tested
01:06and we had so much we couldn't fit it
01:09into one single peer-reviewed paper and
01:11we decided look let's just put
01:14everything up onto a website and put a
01:18date for open peer review so we set up
01:20the open peer-reviewed journal and most
01:23of the work that we will be talking
01:24about you can get on this and we'll talk
01:27a little bit about some newer work in in
01:31the future or towards the end of the
01:33talk but the first part I'm going to
01:35talk about the history of atmospheric
01:37measurements then I'm gonna hand it over
01:39to Michael who's my father and he's
01:43going to talk about the work that I was
01:45describing in the that you can get those
01:47papers on the open peer-reviewed journal
01:49and then finally we're just going to
01:51present a sneak preview of some of the
01:53newer work that we are preparing for
01:56submitting to for peer review so what
02:00I'd like you to get from from this first
02:04part is that all of the models and most
02:10of our understanding of what's happening
02:12in the
02:13atmosphere it's based on measurements
02:15that were done on ground and this so
02:20I'll give you example so this was one of
02:23the first key discoveries which was well
02:27Columbus use it's a great advantage in
02:30that he found that I don't know if you
02:34could see the the map on the thing where
02:36you could see the voyages that were
02:39drawn to the Americas and they found
02:42that by going in a particular direction
02:45go under going west and then East they
02:48were able to take advantage of the
02:50prevailing easterlies and westerlies and
02:52that sped up the journey quite a bit so
02:55this was like obviously a major
02:57advantage so in the 1600 1700 to 1800 s
03:01we had a lot of very prominent
03:04scientists trying to figure out why why
03:07are these prevailing winds there and
03:10these of course were ground-based
03:12measurements there were there real
03:14measurements taken by explorers so you
03:16have people like Hadley Holly of
03:18Halley's Comet fame and Farrell
03:21developing this the other method if you
03:23want to find if you want to go up and
03:27find what's happening higher up in the
03:29atmosphere in the old days you had to
03:31climb a mountain so you actually had
03:35most of the meteorologists when they
03:37wanted to look at what's happening up
03:39would climb up mansions Mont Blanc in
03:42Europe is the highest mountain in Europe
03:44it's five kilometers of a tree three
03:47miles above sea level one of the results
03:50which most of us probably already know
03:53is that as you go up in the atmosphere
03:55it gets colder at height and the lapse
03:59rate the rate which you do is it works
04:03at about 6 and 1/2 degrees Celsius per
04:05kilometer and here's another example
04:08spectroscopy is looking at light and a
04:13parody be I tried a lot of you would
04:16probably be familiar with spectroscopy
04:18but it's essentially you're looking at
04:21the wavelengths of light and different
04:24things and trying to infer in for my
04:26Vitus so the ozone layer was first
04:30identified by looking at air in the
04:33early 20th century by looking at
04:35spectrophotometers and looking at the
04:38light that was coming through the
04:41atmosphere and they noticed that there
04:43were these Peaks are missing bits in the
04:46spectra that were due to ozone and they
04:50realized that ozone was existing
04:53somewhere up in the atmosphere and it
04:55was later identified it's been about 40
04:58kilometers up in the atmosphere is the
05:00ozone layer another example that's quite
05:04well-known it was by John Tyndall who
05:07was an Irish man and so he must have
05:10been good and so he showed that if you
05:14look at the infrared light he found that
05:19if you look in the atmosphere oxygen and
05:22nitrogen are almost transparent to
05:25infrared light but that water vapor co2
05:28and methane that they are infrared
05:30active what we'd call infrared active
05:32that means they can absorb and emit a
05:34particular frequencies of IR and yes
05:40well here we are 50 days if 50 years ago
05:43today the the eagle was landing of
05:49what's launched and I think I told of
05:52the exact time I think it's supposed to
05:54it landed as probably it tomorrow
05:57morning or something like that and so
06:01that was kind of the culmination of a in
06:05many sense the space race and another
06:08aspect of the space race was people
06:10started launching satellites and in 1960
06:14the u.s. started the series of first
06:17weather satellites were launched and
06:20they're still running now we're on I did
06:22the 45th Terra satellite at the moment
06:26so what I just want to show you it's
06:29great now with the space after the space
06:32race we now are able to look from above
06:34the atmosphere but here's what's
06:37happening you know most of our
06:40measurements were done from below the
06:41atmosphere now we're looking at it from
06:43above the atmosphere and if you want to
06:47look at what's inside the atmosphere
06:49that's if you want to understand what's
06:51happening you need to look within the
06:52atmosphere and on the main data set that
06:55you can do is weather balloons so this
06:59has a history going back to the early
07:01late 19th century even earlier but we
07:05had it just on the cusp of the earlier
07:09of the 19 - 20 th century we had a
07:11number of European groups that well
07:13started using both manned and unmanned
07:17weather balloons now I liked I found
07:20this nice drawing by from one of the the
07:24pilots for the German group that was
07:30also a an artist and so he's the guy on
07:34the right holding that bike yellow and
07:37that was Hans gross but he drew that
07:40this painting of what it was like a few
07:43years after he had been in it but
07:46independently about the French group
07:48where it was just using online balloons
07:51and the German group in 1902 they
07:53discovered what we now call the
07:55tropopause though they initially called
07:58it the stratosphere and so what was this
08:01trap a pause stratosphere well you know
08:03as I mentioned earlier on as you go up
08:05in the atmosphere gets colder with
08:08height but they were discovering this
08:10odd phenomenon where it starts to
08:13actually remain constant with height you
08:16go up and it doesn't get colder and
08:18later on it was discovered there was
08:21another region where as you go even
08:22further it starts getting hotter with
08:25height and this was a major puzzle and I
08:30yeah so the the logic all don't from
08:34ground without measurements was that
08:36they were saying well you know hot air
08:39rises I so all else being equal and so
08:42he said well if the temperature is not
08:45getting colder with height you can't
08:47have circulation and so they assumed
08:50must be that the air is stratified
08:53- non mixing layers they didn't actually
08:56notice they weren't measuring her but
08:58they juices an assumption they made and
08:59that's why the name stratosphere came
09:02from that the air was stratified and
09:04they said where is trap us turning or
09:07mixing the troposphere they is mixed so
09:10that was just a ground-based assumption
09:14looking at these fairly weather balloon
09:16models and we can see as you go up in
09:20the atmosphere we now know looking at
09:22using rockets and that you can see that
09:26as you go up even higher the
09:28stratosphere starts to pause again and
09:31then it starts to decrease with height
09:33again then we get another thing we say
09:36we have this back and forth and if you
09:39see a shooting star it's probably in a
09:42random eases fear me suppose region but
09:46for the rest of the talk we're just
09:48gonna focus on the lower tree regions
09:51you see the stratosphere troppo pause
09:54and troposphere and that's the region
09:56that the balloons go up to 35 kilometers
09:59right 20 22 miles or something yeah and
10:03that in terms of the mass of the
10:06atmosphere that comprises 99% of the air
10:11mass so it's the bulk of the mass and
10:15yeah I you yeah so we just the old days
10:21the early balloons they used to put a
10:25little removed a balloon burst it could
10:28land like 200 miles away from where it
10:31was launched so in order to get the data
10:33back they will put a little reward sign
10:36note in with the measurements and saying
10:39if found please return to the
10:41meteorological observatory and you'll
10:43get the equivalent of probably like 20
10:46dollars or something like that but then
10:48in the thirties they invented a radio
10:51transmitters got so cheap that it didn't
10:54became standard so now you'll hear the
10:57term radiosonde used for a weather
11:00balloon sounding sound for sounding and
11:04it was the name came from the
11:06the nautical term where people would
11:08troll a the arduous sounding going down
11:12into the ocean and they said well we're
11:13kind of doing the reverse doing a
11:16sounding going vertically so what in
11:22terms of the development of our
11:24understanding of the current textbook
11:27understanding of climate and atmosphere
11:29there were two main puzzles that were
11:32captivating scientists in the early
11:35night early 20th late nineteenth century
11:38why order ice ages that was the first
11:41one at this stage they already knew that
11:45most have been at least four periods in
11:48the last million years and we now know
11:50there was there's more it's roughly by
11:52ten where the France
11:57yeah Europe and Americas were covered
12:01with glaciers almost covered and then
12:04into a what we now called an integration
12:07period like today where that's not the
12:09case so they wanted to know why did that
12:11happen
12:12the other one was this new discovery of
12:14a trump upon stratosphere under like
12:16what's happening here and because the
12:21ozone layer was discovered around the
12:23same time around 1912 the assumption was
12:28it's probably something to do with the
12:31ozone layer people that are familiar
12:36with the climate change debate now
12:38you'll you might recognize that a lot of
12:41the topics of the theories that people
12:43were proposing for explaining the ice
12:46age non-ace H are still the main topics
12:51of people are doing here changes in
12:53solar variability the Earth's orbit
12:56changes in water cloud cover
12:58co2 volcanic eruptions I the I just
13:03checked it's interesting I was just
13:04talking about on on the next slide but
13:06in the late 19th century one of the
13:08prior the main ones that was being
13:11proposed was that co2 was responsible
13:13for all of the Earth's climate change
13:16and including the ice ages
13:19then nowadays the prevailing consensus
13:23by the IPCC and others is that oh no the
13:26ice ages are due to the Milankovitch
13:30cycles changes in the Earth's orbit but
13:33we are still holding on to this notion
13:36that co2 is dominant for short term a
13:40climate changes so we Michael will talk
13:43a little bit about that later on in his
13:45section but you could just say show you
13:47a lot of people often hear of svante
13:49arrhenius or in the nineteenth century
13:52they already have proved that co2 was
13:54the driver of climate well in the night
13:58Jade said air debate few years later
14:00he's a Swedish colleague contemporary
14:05Noah angstrom who was the son of Anders
14:08angstrom that's the unit is named after
14:10angstrom is named after he went had read
14:13the papers and decided to do experiments
14:16did one of the first systematic reviews
14:19of the IR spectrum of co2 and his
14:23results were saying no co2 was not the
14:26driver George Simpson is a very
14:30interesting guy he was one of the
14:33surviving members of Scott of Antarctic
14:36expedition so he was the meteorological
14:40scientist so he stayed at the base camp
14:43so like many of you will are probably
14:46familiar with jazz
14:48Robert Scott's Antarctic tragic
14:50expedition they got to the South Pole a
14:53few days shortly after Raul Amundsen but
14:58then they they died on the way back but
15:01because George Simpson was still at
15:03Basecamp he survived he later went on to
15:06have a very prestigious career director
15:08at British Meteorological Office he was
15:11knighted and whatever reason that I'm
15:15mentioning it here is in the twenties
15:16and thirties he we looked at both of
15:18those two puzzles and he was using
15:21because he was in a meteorological thing
15:23he had access to all the weather
15:25balloons when he did his analysis his
15:27calculations he concluded co2 was not
15:30the driver of the ice
15:33of climate change he was very
15:35categorical about that they said
15:38temperatures in the troposphere were not
15:42driven by radiative processes which I'll
15:47talk a bit about later and he said and
15:49probably convection was more important
15:52but he argued that the stratosphere his
15:55calculations may be radiation was
15:57involved said is probably something to
15:59do with ozone but he put in two caveats
16:01that there was a lot of inconsistencies
16:03with the theory and the data which
16:06Michael will talk about later on most of
16:09this work was done with very high de
16:13without computers are before with very
16:15early computers and so you were very
16:18limited in what you could do so a
16:20philosophy that seems to been popular
16:22was the peak wanting approach so Gilbert
16:26plus he explicitly stated one of his
16:29papers he was going to try and explain
16:31every possible climate change that
16:33occurred in terms of co2 and his logic
16:36was he said well presumably somebody
16:39else will try and look at other factors
16:41and whatever the truth is between at all
16:44will eventually get to the truth but it
16:46seems that plus nobody else took him up
16:50on that offer and sell a lot of these
16:52say a deteriorate co2 as the driver
16:55relates back to plus and those papers
16:58else a sir he went and he tried to
17:04describe the entire atmospheric
17:06temperature profile using radiative
17:08process is ignoring convection or
17:11anything like that but just using
17:12radiative processes and the
17:14interestingly this was a puzzle because
17:16we he keeps referring to what Einstein
17:19had found in the photoelectric effect
17:21but there's the mention there is no
17:25mention of the name Einstein in his 1942
17:30Harvard monograph and this we were kind
17:32of looking at a Michael pointed H oh
17:35that you know that Einstein was in
17:38Princeton at the time so you couldn't
17:41mention in a Harvard monograph the he
17:43Princeton professor
17:47so you'll see a lot of people referring
17:49to Kirchhoff's laws in when they're
17:52using climate modeling and they're
17:54actually referring to Einsteins laws but
17:57they're using else a sirs book which
17:59rebranded Einstein as Gustav Kirchhoff
18:03had discovered everything was so man
18:05abeyance trickler who they went on that
18:10what later became Noah G FTL's
18:12Princeton ironically Princeton crop' in
18:16a climate modeling group they tried to
18:19use else Asura's data in the sixties to
18:23explain the entire tropopause
18:25stratosphere and troposphere in terms of
18:28radiative processes but there was a big
18:31problem remember I said that the lapse
18:33rate was six and a half degrees per
18:36Celsius per kilometer in the troposphere
18:39when they did their calculations they
18:42kept getting -16 nearly three times the
18:46rate of cooling and they also were
18:50calculating that the ground temperature
18:53was of the order of 160 fahrenheit now I
18:58I'm coming from Ireland so when I
19:00arrived here in Tucson it did feel a
19:03little like that but I think maybe not
19:05that high and so I they did find out
19:11that this stratosphere
19:12kind of looks about right and so George
19:16Simpson that I mentioned earlier the guy
19:19in scott of Antarctica's group he he had
19:23looked did similar calculations that
19:25he'd concluded well clearly the
19:27troposphere is not dominated by the
19:29radiative presses and that's what he was
19:31saying is probably convection mono Bay
19:33and Strickler went a different route
19:35they said so let's just keep adjusting
19:37our models and so what they do is they
19:41would put in a an arbitrary if they
19:44found a lapse rate was getting too high
19:46a rapid after it in during the
19:50simulation they would just artificially
19:52put in a thing to shove the data at
19:55their model thing back so didn't matches
19:57two minus six and a half
19:59they didn't really they said well it's
20:01probably something to do with convection
20:03so it's called the convective adjustment
20:05and the Apollo mission used the IBM 7090
20:13supercomputer and I was incredibly
20:17advanced of course now you have a
20:20smartphone is the only thing that as
20:23everything has gotten bigger with this
20:24rifle the CPU the round the only thing
20:26that's gotten smaller is the size so and
20:30so you would say yes so we've had
20:33massive improvements in the
20:34supercomputers but what have they done
20:37with it climate modelers have improved a
20:40resolution and they've added in extra
20:43components to these two schematics by
20:45the way that you could see under saying
20:47are taken from the IPCC fourth
20:49assessment report this is their own
20:51description the IPC's description of how
20:54climate models have advanced what I want
20:57to point out is that the fundamental
20:59what's called the physics in the jargon
21:03is what they'll use is that doubt that
21:06radiatively dominated was the main
21:08driver that was never checked and they
21:11just keep on using that and the
21:14implications well if the atmosphere is
21:18dominated temperature profile is
21:19dominated by radiative processes well as
21:24Tyndall had shown it co2 and water vapor
21:28on me chain and ozone are the key
21:31components there and so they they said
21:34well if you increase co2 which we now
21:38know is occurring you know Don Manoel
21:40our shows that it has increased then
21:44they predicted so you will get global
21:47warming and they were predicting this in
21:49the 60s manna Bay in wet around 1967 I
21:52think was the first to its will
21:54compliant computer model to make that
21:56prediction and where some other ones a
21:59earlier on but like it was the problem
22:04was that at the time it was global
22:06cooling was occurring from the 40s to
22:09the 70s and so that was a big crowd
22:13but then in the 80s it started warming
22:15again and so the climate modelers
22:17declared vindication and famously a
22:20particular James Hansen and a NASA
22:23modeling group he wedged and testified
22:27for out towards Al Gore and he's as a
22:31result yeah
22:33the greenhouse effect enhanced
22:36greenhouse effect Harry became
22:38mainstream was reported around the world
22:40it led to the setting up of the IPCC the
22:44UN also the UN cop agreement Sola Rosa
22:48where people are trying to cut down co2
22:51emissions and have international
22:53negotiations to do that that all went on
22:57in parallel to while the UN was trying
23:01to negotiate all of these agreements and
23:04the Paris 2015 agreement comes from that
23:07line of the UN the IPCC was supposed to
23:11actually go and check the results but
23:13they'd already decided in 1988 that the
23:18science were settled apparently just
23:22what you end this first part by pointing
23:24out that his quote artists Fame aligned
23:27from Joni Mitchell sang and I think to
23:29do the analogy to paraphrase that people
23:33you know we have looked at the
23:36atmosphere from both sides now from
23:38above the atmosphere and below the
23:41atmosphere but a little you actually
23:43look in the atmosphere you don't really
23:47know what's happening and I'll now hand
23:50over to Michael
23:56I'm just going to briefly summarize the
23:59scientific method because this is what
24:02we use when we're analyzing the weather
24:04balloons we don't use models around like
24:06that and we don't adjust the data we
24:08just use this particular method so
24:10basically what a scientist does is he'll
24:12do a set of experiments we collect a
24:14whole big pile of data and make
24:16observations so we call these facts and
24:19then if he can come up with an equation
24:21that will describe all this set of data
24:23then these are called laws but if you
24:26come up with something new I scientists
24:29really wants to explain why is it
24:31happening laws tell you what happens and
24:33how they happen but they don't tell you
24:35why so the first thing you do then is
24:37you make a guess as to why it happens
24:40and we call this a hypothesis and this
24:42is where the scientific method comes in
24:44because what as a scientist you're Danah
24:47obliged to put your guess to all of the
24:51tests than you can think of and maybe
24:53get other people to come up with other
24:54tests and what happens is if it survives
24:57all the tests then you have a theory and
25:01but the unfortunate thing is if if any
25:05facts are not explained by your guests
25:08or your hypothesis then it's wrong so
25:12that's what summed up by famously by
25:16Richard Feynman where he said it doesn't
25:18matter how smart a person is it doesn't
25:20matter how beautiful the hypothesis is
25:23one ugly fact that disagrees was it
25:26destroys the whole thing so the other
25:30thing is that if you have two or more
25:32theories that explain all the facts then
25:34what we use is the principle of Occam's
25:36razor who was an 11th century monk and
25:38he said if two or more theories explain
25:40all the facts pick the simplest one so
25:43that basically is the scientific method
25:45in a nutshell now let's have a look at
25:48the weather balloon data this is typical
25:51weather balloon and attached onto the
25:53bottom of it there you'll see the little
25:55instrument package which measures the
25:57temperatures and so on
25:59and what do you get from this weather
26:01balloon the weather balloon now adays
26:03they're filled with hydrogen or helium
26:05and they go up to about 25 miles
26:09then they burst and all the way up there
26:11sending back all the disinformation it
26:13takes about 90 minutes for it to get to
26:1525 miles or so and this is what you'll
26:19get back a whole list of data now this
26:21is only about a third of the data but it
26:23gets the point across and what you can
26:25see is that there are temperature
26:27measurements pressure measurements and
26:30so on and then there are certain levels
26:33called mandated pressure levels which
26:35I've underlined some of them they're the
26:37ones on this section in red and they're
26:40obliged to take those measurements
26:42regardless so what do you get when you
26:45have your weather balloon data well here
26:48I've taken the weather balloon data from
26:51this day last year in Tucson and also
26:55one on the first of January for this
26:56year in Tucson and I've plotted here the
26:59temperature versus the the height or the
27:05pressure as you go up so down the green
27:07bit down there represents the ground and
27:09the top scale across there is in degrees
27:12Kelvin which is the scientifically used
27:15temperature it's zero degrees centigrade
27:19or 32 degrees Fahrenheit this 273
27:22degrees Kelvin so you can see on the
27:25Tucson one there the temperature is
27:28about 31 32 that would be or sorry 310
27:33or something like that that would be
27:35about 40 degrees centigrade or 107
27:38Fahrenheit so I just picked the January
27:43and July one one is in the evening of
27:45one is in the morning for to illustrate
27:48the difference between summer and winter
27:51and day and night and before I can start
27:54showing you how we analyze that I have
27:56to summarize the gas laws I'm sorry to
27:59have to bore you with this but I know
28:01most of you may have forgotten most of
28:03them so this is a quick summary Boyle
28:06who again was another Irishman and had
28:08to be write as well he he said that if
28:12you increase the pressure on the gas it
28:15gets smaller so if you double the
28:18pressure you have the volume if you have
28:20the pressure you get the ball you
28:23with double the volume and then you had
28:25Charles the slow who was in a French man
28:30and he was the first guy to ever man a
28:33balloon so he's the first month flush in
28:38a balloon he said if you heat a gas it
28:40expands and if you cool the gas it's
28:43easier to squeeze it back down into a
28:45small volume again and the last law that
28:48we have in the gas laws is Avogadro's
28:50law and he just simply said that if you
28:54have two gases occupying the same volume
28:57it doesn't matter what the gases are one
29:00could be hydrogen a very light gas the
29:02other might be carbon dioxide which is a
29:04lot heavier and made up of three atoms
29:06the type of atoms or molecules doesn't
29:10matter all that matters is that they
29:12have the same number of molecules in the
29:16gas if they occupy the same volume they
29:18have the same number and we measured
29:21count the number of molecules in a unit
29:23called moles a mole is a very large
29:26number there it's six by ten to the 23
29:29and in honor of abogado it's called
29:32Avogadro's numbers so n therefore is the
29:36number of moles that you would have in
29:38the cubic meter of air so if you combine
29:42those three gases together are those
29:44three gas laws together you guys what's
29:46called the ideal gas law and the
29:49internal dynamics this represents the
29:51equation of state of the ideal gas so
29:54basically in terms of dynamics if if a
29:58gas is obeying the gas law it's said to
30:01be in thermodynamic equilibrium and this
30:03would be an important point that we'll
30:05get to later on so you can rearrange the
30:10gas law or the equation of state into
30:12the molar density form and what you'll
30:15see then is you get D which is n over P
30:20the number of moles per unit volume or
30:22per square meter cubic meter that's
30:26what it tells you is that if D is very
30:29low the molecules are spread far apart
30:31and if D is very high the molecules are
30:35squashed close together so how does this
30:39allow us to analyze the weather balloon
30:42data well the first thing I'll tell you
30:44is nobody I know of on to myself and
30:48Ronin have analyzed the weather balloon
30:50data in terms of D the molar density
30:53even though it is an equation of state
30:57it's just representing the same one in a
30:59slightly different form but nobody
31:01taught to analyze the data in this
31:04particular way and the reason why this
31:09is of use is that if you take this
31:11January profile here and look at how the
31:13temperature is changing as you go up
31:15through the atmosphere it's fairly
31:16wobbling back and forth and so on but if
31:19I transfer that data and represent it in
31:22terms of molar density what I end up
31:25with is two straight lines and this is
31:27what's quite a surprise and just to show
31:31you that these really are straight lines
31:33you can see the little circles represent
31:36the actual measurements and if you look
31:39at the correlation it shows it's
31:42extremely good at the r-squared factor
31:44if it's one it means it's a perfect
31:46straight line if it's zero there's no
31:48linear correlation at all but these
31:50these started things are quite good now
31:53the thing is that that one was one taken
31:58in the evening hour sorry taken in the
32:00morning what we find is if you take it
32:03you're in the day after the Sun has
32:05heated up the ground level is
32:07represented by a third line but the
32:10interesting and I get into that a bit
32:12later the interesting thing is that we
32:15can now find that we can divide the
32:17atmosphere into three different regions
32:20and each of these have their own staff
32:24at a separate equation of state so that
32:26means within each of these regions the
32:28air is in term of dynamic equilibrium
32:30and that will have implications that are
32:33get into later and the other thing is
32:35that at night when the sun goes down you
32:37lose that bottom
32:39and it just becomes the same as the rest
32:41of the tropopause
32:42so we analyzed all of the 20 million
32:45radio songs that have been launched
32:48since the 1950s I spent over an hour
32:51counting him we found that there were
32:54the same thing applied to all 20 million
32:57there was two day reader represented by
33:00two straight lines or three straight
33:02lines depending on where the rose day or
33:04night and to show that this wasn't just
33:07cherry picking - what I have done is we
33:11did the video for all of the radio songs
33:14for Tucson here for last year and what
33:19you can see here again as the vertical
33:22axis is the term pressure you're going
33:24from the ground upwards but the thing I
33:26want you to take away from this is that
33:27if you look at the right hand side I
33:29fetched it just need to nitrate once I
33:32didn't bother with the day once because
33:33it would have been wiggling back and
33:34forward a bit but if you look there you
33:36can see that all of the the weather
33:40balloon dieters are all fitted by the
33:42same two straight lines but the
33:44interesting thing is the horizontal line
33:47shows for these two lines intersects and
33:49that's the start of the tropopause every
33:52single time and thing about it is as
33:55jumps up and down it can jump up by boat
33:57and down by as much as 20 percent of the
34:00atmosphere in as little as 12 hours it's
34:02a very rapidly changing phenomenon which
34:05has a lot of implications so if we get
34:07into later
34:08so just to continually explanation then
34:11I I just want to rotate the dis graph by
34:1690 degrees so that the ground is on the
34:20right-hand side and the pressure is on
34:24the bottom and the molar density is the
34:25vertical axis so that's what I'm doing
34:28here
34:28and the reason I do this is that as
34:30chemists it's quite common for us to
34:32want to measure how the molar density
34:35behaves with with pressure because it
34:37tells us something about the
34:38compressibility of a gas so normally you
34:42take an ideal gas and by the way under
34:44the conditions that we have in the
34:45atmosphere oxygen hydrogen carbon
34:48dioxide meter and they are all ideal
34:51gases
34:51so under
34:53circumstance and water vapor is an ideal
34:55gas provided the humidity is less than
34:58100 but if you increase the humidity
35:01above a hundred then it ceases to be an
35:03ideal gas that's just a side effect so
35:07the thing about a gas is the more
35:10compressible it is the easier it is to
35:12squeeze it down this the flatter the
35:15slope would be so you can see here the
35:18red data points showing if are the
35:20troposphere the lower section of the
35:22atmosphere the gas has a certain
35:25compressibility and then when it hits
35:27the tropopause for some reason the gas
35:30becomes easier to compress now this
35:33turns out to be a killer blow for the
35:36ozone heating hypothesis which I'll
35:38explain why in a minute
35:41to demonstrate this in a slightly
35:45different way here we have the two songs
35:48that I showed earlier I've put the
35:49temperatures on top of each other so the
35:52red one represents the summer
35:54temperature for this day last year in
35:56Tucson and the blue one represents the
36:00are is the temperature for the winter
36:04night one and when you look at the molar
36:07density one you can see yes we get the
36:09straight lines it's turned into straight
36:11lines and you can see that the slope of
36:14the red one the hotter one is less than
36:16the slope of the green one are the blue
36:19one the the colder one and this is
36:22exactly what you would expect from
36:24Charles's law if you put more energy
36:26into the gas it becomes harder to
36:28compress and the slope becomes less and
36:31I can show you this again just on a day
36:34night one this was the same one taken in
36:36January I had ended it in the morning on
36:40a tonight and what you can see here is
36:42that journaling today the ground-level
36:44heats up but at night it cools down but
36:48the rest of the troposphere doesn't
36:51change temperature this is a quite a
36:53surprise and I nobody seems to a father
36:56looking at this until now so these are
37:00the different models that they had for
37:03the tropopause that was come up by the
37:06American atmospheric standards in 1972
37:10but I just show what the problems is
37:14with the with the the thing is maybe I
37:20didn't I skipped the point at this slide
37:24here you can see that if you heat the
37:26gas it becomes more compressible except
37:29in the tropicals where the slope is much
37:32bigger it's about 50% bigger so this is
37:37why the ozone hypothesis heating
37:40hypothesis fails because if it was
37:42heating the tropopause it will become
37:44harder to compress the slope should have
37:46gone the other way
37:47it shouldn't have got steeper it should
37:49have got less so because that is not
37:51what happens that's why the ozone
37:53hypothesis evening hypothesis fails we
37:56have to come up with a different
37:57hypothesis so I'm looking here down at
38:00all the different things once we
38:01realized and that the whole zone
38:03hypothesis is a failure we see that
38:06there were a lot of other things that we
38:07could have looked at to let us know that
38:09as well one is why is this warmer in the
38:12polar winters in the stratosphere when
38:15there's no UV light at all it's dark and
38:18why is it that in these tropical
38:21tropopause the temperature is colder
38:24than it is in the other ones because
38:27resume li there's more UV light so we
38:30can see all of these things where you
38:33have problems with the ozone heating
38:35hypothesis we just have to say it's
38:38failed it doesn't work we now need to
38:40come up with something else and we have
38:43put forward this hypothesis here again
38:45it's a hypothesis it's a test we've
38:48subjected it to a lot of tests and it's
38:50held up so far but not enough for us to
38:52say this is a theory this explains
38:55everything because I don't think we've
38:57done enough testing of it yet but you
38:59can see if we went back to the ideal gas
39:04law if you looked at the equation down
39:07at the bottom if I keep the temperature
39:09or if I keep the pressure constant and I
39:11have and I want to change the
39:13temperature one way I could do was be
39:15add heat into it which is what was
39:17proposed and that would cause the
39:18temperature to go up
39:20another way we could have done that was
39:22with we reduced end a number of
39:24molecules then to keep the equation
39:26balanced we would have had to rise the
39:29temperature and so our particular thing
39:31says that if some of the molecules and
39:33the implications from our tests so far
39:35is that it's oxygen if it combines yeah
39:39if if if it combines to form multimers
39:43then what happens does that reduces the
39:47number of molecules and that would mean
39:49that the temperature would go up as well
39:51so this does explain why the temperature
39:54would go up without ozone heating so
39:58getting back to the ideal gas law what
40:01you have is what it says is that if a
40:05gas is in terms of dynamic equilibrium
40:07that the work component the PV section
40:10is balanced by the terminal component
40:13the RT section and you can use this to
40:20that second line there's P D and P and
40:24we can calculate T so let's go back here
40:27to this particular graph and we can see
40:30then what we have is is this is during
40:33the evening when the Sun has heated up
40:35we have our three particular equations
40:38of state and what we can see is that if
40:41I reuse the these straight lines
40:43I can refit the temperature profile and
40:46you could see then we get again our
40:50three different regions except the
40:52changes from one state to the other but
40:54what we can say now because we have
40:56three equations of stage one for each of
40:59the boundaries then each of those layers
41:03is in thermodynamic equilibrium and this
41:05turns out to be a very important thing
41:08when we get on to looking at the carbon
41:10dioxide behavior so that's just a
41:16summary there I just want to compare our
41:18three equations of state model for the
41:21temperature profile with the manna Bay
41:24and strickler connect radiative
41:27convective model which is used by the
41:29modelers today and I think there's no
41:32comparison
41:34you can if you find it hard to see the
41:36black line data with the two with the
41:38three different things I'll get onto
41:41this again a bit later let's go down
41:44okay so in terms of dynamics just to
41:47explain what thermodynamics is with the
41:50invention of the steam engine they were
41:53trying to come up with ways of improving
41:54the efficiency so you were turning heat
41:57from burning fuel into mechanical energy
42:01and that's why the H is the terminal bit
42:05of the name and the diamond dynamism are
42:08the diamond economic or movement end is
42:10where it got the name thermodynamics so
42:13it's a study of the relationship between
42:15mechanical energy and thermal energy and
42:19so are there a number of term a dynamic
42:22laws but one of them well-known that
42:24will be used and mainly here is that
42:26energy cannot be created or destroyed
42:29however it can be changed from one form
42:31to another and it also can be
42:34transmitted from one place to the other
42:36you could for example have a hot glass
42:38of water and move it to another spot and
42:41still you've changed the energy from one
42:43side of the room to the other and so on
42:45what what the first law doesn't tell you
42:48is the rate at which these processes
42:51happen so you yeah how fast can you move
42:54heat from one spot to another or how
42:56fast does it change from mechanical to
42:59terminal the first law doesn't tell you
43:02that instead we have to resort to
43:03measurements and what we look at is we
43:06have a number of different mechanisms
43:08have been proved provided for to say how
43:11energy can be transmitted from one stage
43:14to the other and these are the only
43:17mechanisms that are used in the computer
43:20models that try to profile the
43:22atmosphere and what we ask is is this
43:25enough
43:26is there something missing and what we
43:28soon discovered was yes
43:30there is so up until now people have
43:33been saying conduction convection
43:35radiation and acoustic like I'm talking
43:38to you so I'm sending energy through the
43:42air but not at the air doesn't actually
43:45travel to you
43:46and I'm have we've arranged a simple
43:49experiment here that should have been
43:51done years ago
43:52and we'll point out an overlooked
43:54mechanism for transferring heat through
43:57the atmosphere so do you want to do that
44:00yeah so what we've done is we have here
44:04a 100 meter a hundred 100-yard sorry
44:12what we have here is a hundred yard
44:15piece of tubing going from one end of
44:17the hall to the other and we have here a
44:21plunger that's it so if you pull that up
44:24Ronen yeah if you post that up what you
44:27can see is within a few seconds the a
44:31liquid is being sucked up in the tube
44:33and if you push it back down again the
44:35liquid has been pushed back down it's
44:37it's the biggest length longest single
44:40use plastic tube that we have at the
44:42moment so see if you just see the red
44:47bit there just lift it up again you can
44:50see how rapid the response is now this
44:53is a very controlled exponent up a bit
44:55higher Darren yeah this is a very
44:56controlled experiment this experiment we
44:59can calculate how all the different
45:01mechanisms try to contribute to causing
45:06us to do this work on the underwater in
45:10the container
45:14I'm applying here work energy you know
45:18this is PV I'm moving it and the work
45:23energy is being transmitted through this
45:25big long a hundred meter tube which
45:29contains air and then it's the energy is
45:33ending up over here the work energy has
45:34been done at the other end so so this is
45:37mechanical energy so this is a mechanism
45:40of transmitting energy mechanically but
45:43now up until now all the models have
45:45been worried about transmitting energy
45:47using terminal processes so we have
45:50calculated exactly what the energy
45:52transmission is for each of these
45:54mechanisms and you can see here that the
45:57overall rate at which the energy has
45:59been trans
46:00mr. down along that tube it's a very
46:01small narrow tube but if we were to make
46:03a 1 meter square that will be two and a
46:06half thousand watts of energy is the
46:09rate of energy transferred out in our
46:11data - whereas all the methods just used
46:14by the way the computer models and the
46:17theories up until now come to less than
46:202 watts so for some bizarre reason
46:22people have ignored a net energy
46:26transmission mechanism that's three
46:30orders of magnitude greater than any of
46:33the others and we look to see if where
46:36people would describe this in the
46:38literature and there wasn't anything we
46:40had to come up with our own name for it
46:42which we call perfection another term
46:45would be you know true mass energy
46:48transmission mechanical energy
46:50transmitted so this can go against the
46:53temperature that water could be colder
46:56or hotter it wouldn't affect the rate of
46:58which the mechanical energy is
46:59transmitted so it's independent of the
47:02eternal transmission mechanism so in
47:04other words we could freeze the syringe
47:07of one end and heat that up to boiling
47:09water and the energy would still
47:11mechanical energy would transmit from
47:13the colder to the Harvard direction yeah
47:15so just give an explanation for how this
47:19would happen here we have the famous
47:21Newton's Cradle and if you apply
47:23mechanical energy you can see imagine
47:26that they are the atoms inside in the
47:28tube you can see you apply the
47:30mechanical energy of one end it comes
47:32out the other end but the molecules in
47:33between don't move they vibrate back and
47:37forth a bit but they don't move from one
47:39end of the device to the other and this
47:41is what we think is happening yes I just
47:43just show it in that like again what
47:46we're doing here is this is obviously
47:49not by air but you can see that like I'm
47:52applying work energy here and the work
47:56energy ends up on the other side but the
47:58the balls in between they're staying
48:01where they are so the the energy is
48:03being transmitted from one side to the
48:05other the interesting thing is that this
48:08mechanism that's happening in the
48:11Newton's Cradle can't be described using
48:14the standard models maybe now we'll have
48:17take include perfection into it it might
48:20be possible what we're saying is we
48:24believe that there are greenhouse gases
48:27that they adsorbed energy and they emit
48:31energy and one of the of Einstein's
48:35famous paper that he published exactly a
48:38hundred years ago today in 1919 he
48:42showed that if a gas was in
48:44thermodynamic equilibrium the rate of
48:47adsorption by an infrared gas the rate
48:51of adsorption was equal to the rate of
48:53emission so in other words if you
48:55increase the amount of infrared active
48:58gases in the atmosphere you will
49:00increase the rate of absorption but at
49:02the exact same time you will increase
49:05the rate of emission so if the gas is in
49:09thermodynamics equilibrium you won't get
49:11a greenhouse effect it won't store the
49:14energy and what we have shown by our
49:16data is yes the gas the air is in terms
49:19of dynamic equilibrium
49:20now the climate models have decided to
49:24ignore Einsteins Einstein when he came
49:28up with the equation he said the rate of
49:29adsorption is equal to the rate of
49:31emission but there were two types of
49:33emission one was the standard emission
49:35from a hot body a random one the other
49:37one is photo induced emission and this
49:40is the emission that's used for to
49:41develop lasers and so on but what that
49:44says is that and what will happen is
49:49that the infrared active gases will aid
49:52the transfer of energy from a hot area
49:55to a cold area but it won't store the
49:58energy so let me go back to then
50:02comparing the night and day what I'm
50:06looking at here is showing you that this
50:10this is not a a one-off event the one
50:14that I showed you in January here's
50:16Tucson for the start of this month the
50:18first week or so and what I want to draw
50:20your attention to is that every night
50:23day the temperature gets heated up and
50:25every day it cools down at night
50:27but the Sentra bit the central purpose
50:30that doesn't go through rapid
50:32temperature changes so what happens to
50:34the energy that's stored in the boundary
50:37layer remember you're talking of about
50:38two and a half tons of there air per
50:42square meter it's a lot of energy and
50:44this is just representing it another way
50:47the bottom axis is time so this is for
50:50the entire month of May you can see a
50:52ground level the temperature zooms up
50:54and down and by the time you get up to
50:57700 that day/night variation is gone but
51:01the lower upper ones they are but they
51:04they don't have the same day/night
51:07effect the other thing that I want to
51:10point out here is that and that that
51:14energy data what we're told is that
51:17supposed to be heating up the as you can
51:20see here I've plotted the humidity the
51:22amount of water vapor in grams per cubic
51:24meter that was in the atmosphere that
51:27you also get from the same radio balloon
51:28data and if what we are led to believe
51:32we're true what we should see is that
51:34energy at night it's going it's
51:37vanishing he's going somewhere I say
51:40it's going out to space but if it was
51:41being trapped by infrared gases then on
51:45the third slide tree inside for that's
51:48interesting our side six you have a
51:51water vapor there in the atmosphere at
51:54the night so that should be trapping the
51:56atmosphere what it actually does is it
51:58cools it in other words the atmosphere
52:00is behaving exactly as Einstein's law
52:02predicts and not as the global warming
52:05things so in other words the infrared
52:08water vapor is serving to cool the
52:10atmosphere at night even faster and the
52:14other thing that you'll see is that the
52:18that during the day the water vapor
52:21there that are actually he helped the
52:23atmosphere it's true because you've got
52:25the sunlight coming in and that sunlight
52:27that has been adsorbed and if you looked
52:30at the spectrum we showed earlier that's
52:32why we we see the water vapor things so
52:37we'll go on to our new findings but what
52:40I can say is
52:41the data from the weather balloons has
52:44shown quite categorically there is no
52:47greenhouse effect increasing greenhouse
52:49gases will increase the rate of
52:52adsorption but because the atmosphere is
52:54internal dynamic equilibrium it also
52:56increases the rate of emission the next
52:58net effect is no okay so yeah there's a
53:08lot of material there and like we'd
53:10encourage you to to read Stone to look
53:12at true the those papers that are on
53:15that opha website and we are that was
53:20like five years ago that we put put
53:22those but like we we haven't gone static
53:25since then and so we continue to it's
53:28we've also been writing a lot of papers
53:30with Williams yeah yeah yes but we have
53:32been carrying out this other work and
53:34this work is again we would be
53:36publishing with really shortly yeah yeah
53:38so we're just writing up at the process
53:41a a couple of papers I we don't I don't
53:44know we don't have a whole lot of time
53:45so we'll just kind of speed through this
53:47just to give you a flavor of what's
53:49coming down the tracks
53:51and just okay on the laps rate um this
53:57is the under on the left hand side you
54:00could see the standard atmosphere and
54:03the lapse rates as you go up in the
54:05atmosphere according to that and you can
54:07see it's a very lot of straight lines
54:10what we've done on the right hand side
54:12is we've looked at I think there's about
54:14five million weather balloons used for
54:17compiling those particular averages I
54:20going back to the 50s and in some cases
54:23even further and what we're finding is
54:25broadly they if you were to try and fit
54:29the right hand graphs in terms of
54:31straight lines it's it's it's kind of
54:33okay but the reality is that the lapse
54:36rate isn't as straight it's not exactly
54:40six and a half it's it changes and you
54:43know the next point is those are
54:44averages at any given a mandated level
54:50if you look at the lapse rates there the
54:52average is of the order of six
54:55and a half and the troposphere well you
54:57need to look at histograms so it's not a
55:00constant and the implications of that
55:04are well as weather hurry on this one
55:06okay so what deviations can't remember
55:09the convective adjustment that was
55:11assuming that the lapse rate was exactly
55:13six and a half it's not there's a lot of
55:16variability and there's an intriguing
55:18paradox that's implicit in the current
55:21models what they're doing is they're
55:24assuming that I would talk about this in
55:26a second but that each of the layers of
55:29the atmosphere is Termidor analytically
55:32isolated from above and be lowered
55:33that's how the the greenhouse effect is
55:37supposed to lead to certain parts of the
55:39atmosphere heating up from the IR
55:41activity but simultaneously they're
55:44assuming a constant fixed lapse rate so
55:47what they're saying is if the
55:49temperature I J 500 millibars increases
55:53because of co2 half a degree that is
55:56simultaneously occurring at the ground
55:59so you in other words that it's there
56:03turbo dynamically connected so you can't
56:06you know they want to eat their cake and
56:09still have it I hear you wants you to
56:13talk about this one yeah yeah just
56:15quickly okay so so this is taken in
56:20Germany the reason we use that was that
56:22Germany has a very good radio song
56:26program they emit for send up for every
56:30day and so we have twice as much data on
56:33any one day again you can see the exact
56:35same phenomena the day/night thing is is
56:38but now it has four points in it by the
56:41time you get up to 850 it's almost gone
56:44and you can't see any trace of it then
56:46but here is the interesting thing if you
56:48look between the four hundred they well
56:52if you look at the five hundred and two
56:56450 what are the four hundred one you
56:58see their synchronization there between
57:00them it's not a 24-hour synchronization
57:04but it's some of the order of four three
57:07or four days but the interesting
57:09is that if you look at the 201 above the
57:12strata at the start started stratosphere
57:15that's an T synchronized it's going in
57:17the opposite direction so what it is
57:19happening is whatever's causing this
57:21change in the compressibility of the gas
57:26whether it's our multimeric hypothesis
57:28or something else if the area that come
57:31compressed jumps way down which is what
57:34we saw from the video then that would
57:37mean that we're decreasing we would be
57:40making a sort of partial vacuum and that
57:42we would be sucking up the air from down
57:44below I'm pulling the air from the
57:47stratosphere down now if you pull air
57:49upwards it gets colder and if you pull
57:52it down it gets warmer and that's why we
57:55think that you have this anti
57:57synchronized raishin above this stratify
58:00the tropopause it's going in one
58:03direction it's going down or up and it's
58:06doing the alterations so what Michael is
58:08describing by the correlations and anti
58:10correlations we weave what we're doing
58:13here is what we find is the temperature
58:16at which that phase changed that's the
58:19the point of intersection between those
58:22two lines if you recall of the molar
58:23density pressure plots the point of
58:26intersection if we measure the
58:27temperature there we find that that
58:29temperature goes up and down up and down
58:31if you look at the ground temperature
58:33that goes up and down and what we're
58:35finding is if you take for a given time
58:38of the day two we can to remove the
58:41day/night effect you can look and see
58:45how is the temperatures at each of the
58:47mandated levels correlated to the ground
58:51temperature TG and the temperature of
58:54the phase change TP and we're looking at
58:59just for one zone for this preview here
59:02which is 470 stations by 10 million
59:06balloons over a 30-year period from 1989
59:10to 2018
59:11this is just for January we're just
59:13showing you what we find is that the
59:16temperature changes at ground are quite
59:20correlated to the changes as you go from
59:23the album
59:23is fear that's the one on the left but
59:26she can see that it rapidly falls off
59:28and that up near the stratosphere it
59:31actually comes slightly anti-correlated
59:33but there's almost no correlation if
59:35however we look at the phase change the
59:38TP this is the point of intersection if
59:41we look at a temperature of that dashed
59:44black line in the video Michael was
59:46showing you um that correlates far
59:49better with the bulk of the atmosphere
59:51like we're talking of seventy percent
59:52its anti-correlated in the troposphere
59:55uncorrelated above the troposphere and I
60:00what you do or squared you can see this
60:04and I just want to stress sorry I just
60:06want to stress that graph on the right
60:09nobody has been looking at this check
60:12this intersection of molar density plots
60:15before so this is a new result
60:17completely near nobody is looking at it
60:20it's it's and that seems to be the one
60:23that seems to explain everything best
60:25just what we think for the climate
60:29models like my background is in computer
60:31modeling that was my PhD I'm not a
60:34critic of computer models as so they're
60:37very useful to but they should be
60:40continually compared with data and
60:42observations so you know there is a
60:45nobody has been looking at this they've
60:48just been assuming the models are the
60:50best we've got and we should be checking
60:54at experiments and so um there are the
60:58different improvements we believe should
61:00be made I don't know if there's time for
61:03questions we have another three minutes
61:05before the clock actually heats so eight
61:08minutes eight minutes okay oh yeah with
61:12questions yeah
61:21I'm a retired operational weather guy I
61:24used to be the weather unit commander
61:25here four years ago at davis-monthan and
61:28now also a sail plane pilot so all the
61:32stuff that you're saying makes perfect
61:33sense like I say I come to this from an
61:37operational weather point of view we
61:42know that the atmosphere is transparent
61:46to visible radiation yes and that's what
61:49you're showing yes and where there are
61:52no greenhouse gases it's travel
61:54transparent to the infrared radiation as
61:57well yeah oh yeah yeah but but another
62:02thing I want to point out is that if you
62:04look at the newspapers the newspapers
62:07have a lot of information if only the
62:10people critiquing this would pay
62:13attention one example was about a year
62:17and a half ago in Siberia it got as cold
62:20as it ever gets in the northern
62:23hemisphere it was in USA USA today well
62:27if it's as cold as it ever has been in
62:30the northern hemisphere where's the
62:32trapped Heat yeah also you go up to
62:35Canada you know Edmonton breaks the the
62:40cold temperature by 12 Celsius 20
62:44Fahrenheit not just Edmonton but a
62:47hundred kilometers around it where's the
62:49trapped heat obviously it doesn't exist
62:51that's all I want to say thank you
62:52George your talk how we agree with you
62:56on your slide summary of prevention
63:00experiment yeah the term that overwhelms
63:03that discussion is the acoustic
63:06transmission 1.4 watts per meter squared
63:10I've lost on acoustic transmission okay
63:13acoustic transmission is how you
63:15communicated with me in other words when
63:18you moved your tongue you created
63:20vibrations in the air which was
63:22mechanical energy which then came and
63:24vibrated my ear so that's what acoustic
63:27transmission is just sound sound waves
63:31and it so happens that that particular
63:32experiment we've devised there is a low
63:37pass filter so anything with a frequency
63:39of less than one Hertz wouldn't be able
63:42to pass through it and so what we're
63:44saying is the acoustic energy can't get
63:47through that but I'd like to just add
63:49just a point which we discuss in the in
63:52the papers referring to that I think
63:54it's the third paper on that open your j
63:56website but you can think of you have AC
64:00and DC in like an electric city you have
64:04this alternating current and then you
64:06have a DC based signal and so we could
64:11think of because acoustic energy or
64:13sound is a wave format you could think
64:16of it as honesty akuti a c component of
64:21of mechanical energy transmission but
64:25what world of describing here is the DC
64:28component of mechanical energy
64:30transmission so while it is obviously
64:33sound has been studied very heavily so
64:37everyone is very familiar of sound as
64:39Atlantic in a sum of transmission we're
64:41actually saying is and this is well
64:43known to aircraft engineers and I just
64:45think there's a few of them around here
64:47what actually happens is that if an
64:51airplane is traveling at less than a
64:53tenth of the speed of sound then the air
64:55is best treated as if it's not
64:57compressible as if it's a non
65:00compressible material and what that
65:03means is it acts like a rigid rod so you
65:06could look upon this big long tube of
65:08air because it's taking its traveling at
65:10about 34 meters per second less than the
65:13speed of sound or less than 10% so it's
65:16like as if it's a long rigid rod and you
65:19just push it at one end and it sticks
65:21out the other end and we after you do
65:25record I will around the record yeah
65:27heard of the giant Large Hadron Collider
65:34well we have called this here is the
65:37Large Hadron Collider because of what
65:40it's doing to all those beautiful models
65:42I got one one last question here simple
65:47energy energy transfer and in my I'm a
65:52geophysicist and one of the things that
65:54occurs to me is is that we have a lot of
65:56solar interaction with our with earth
65:59and energy being transmitted from our
66:02borealis and and-and-and the Aurora's
66:06that we see and when we wonder if
66:08there's at those high altitudes whether
66:11and whether any of that energy impacts
66:13our gases in the atmosphere well in
66:17those diagrams that we showed you there
66:19where the phase change was moving up and
66:23down and we found that when you dampened
66:25out the day-night thing you were still
66:27getting these fluctuations what causes
66:30that we don't know yet that's still an
66:33open question there are the reason it's
66:38an open question there's nobody even
66:39thought to ask it until now
