I forgot about evil e, who is sort of an insane person. > [@Evil\_Economist](#): > > Do you ever realize how badly you got your ass handed to you? Holy shit, I’d never show my face on the board again if I got handled like that. Congratulations on not having any shame, I guess. What sort of person considers being wrong, or right, in a science argument, with shame? I blame politics somehow. I also forgot I linked to the other thread the last time this moron started pestering for attention. > [@FXMastermind](#): > > There isn’t a single thing in that post that isn’t linked to, actual sources, so anyone can check the data themselves. > > [Even the WFTs links are still valid](http://woodfortrees.org/plot/crutem3vnh/from:2002.9/every:12/plot/crutem3vnh/from:2002/every:12/plot/crutem3vnh/from:2002.08/every:12/plot/crutem3vnh/from:2002/trend), since the newer data is in them. > > Th thing that is so hard for a non-scientist to grasp, is that basic global warming theory predicts the NH land should show the most warming, and in winter. > > And that land temperatures should show more warming than the oceans. > > That we observe a cooling trend for the boreal winters, while the NH ocean still shows warming, is also a big question mark. > > It’s such an obvious problem, it’s quite interesting to see a blank eyed stare, or raging anger, when confronted with these facts. > > Because I also say it does not mean there is no human caused changes, and in fact consider Cohen’s theory to be quite possible, certainly the fossil fuel influence isn’t happy with my showing the data either. > > Just because basic global warming theory is wrong, does not mean we aren’t fucking things up. As I have said many times, if Cohen (and others) are right, it means the trends will continue, and winters will get worse, while the rest of the year warms. This is a worst case scenario, as it means far more damage to us, than just warming winters would cause. > > If it is actually from fossil fuels/deforestation/cement making, you know, the sources of increased CO2 levels, it could be a very bad thing. What seems to happen, is the nutjobs (and fuckheads) think any criticism or challenge to the AGW theory (CO2 theory, basic global warming theory) is some monstrous attempt to subvert science for political reasons, meaning “I fucking love coal” or “he must be getting paid to post this crap”, both of which are completely wrong. But trying to correct that level of wrong is a complete waste of time, and since they didn’t use logic and reason and facts to reach their conclusion, no amount of facts or logic can reason them out of it. It’s a belief. ---

Or, we can do like Judah Cohen did, and modify the theory, and create a model that includes the effects of snow extent, hoping to be able to predict what will happen. Because it is indeed a theory, [we can also discuss the results of the predictions](http://www.bloomberg.com/news/articles/2015-03-04/siberian-snow-cover-theory-proves-less-than-perfect-this-winter), which would be scientific and all that. > [@](#): > > So, with the season more or less done, how did the theory linking Siberia’s October snow cover with the severity of U.S. and European cold make out? > > The author of the theory, Judah Cohen, said it was a bit of a mixed bag. > > “The forecast for the U.S. was phenomenal,” said Cohen, director of seasonal forecasting at Atmospheric and Environmental Research in Lexington, Massachusetts. “As far as I know, the Siberian snow cover was the only thing that called for an extreme winter.” > > For Europe, which was relatively mild, the indicator “was far from perfect,” he said.

For everyone still fighting the good fight, it’s now page 97. We have excessive proof that he isn’t going to listen to an argument and say yeah, you’re right (and if he does, he’ll immediately return to the bullshit). He [refuses to state his thesis](http://boards.straightdope.com/sdmb/showthread.php?p=18575409#post18575409), which makes arguing against it impossible. On the occasions that he says he wants to discuss the science, he [refuses to follow through](http://boards.straightdope.com/sdmb/showthread.php?p=18637532#post18637532) when taken up on it. I get the point that we’re arguing not for him, but for the sake of everyone else who comes across the thread; I made my attempts at this too. But it’s fucking page 97. No one is going to come across this and think, “you know, this FXM guy makes a good point.” He has demonstrated his complete inability to present a cohesive argument, let alone a persuasive one. He has been caught in innumerable lies, and his retorts that _he’s_ not the one lying don’t make him look right, they make him look insane. So let him return to posting to himself. Who cares if he makes 10 posts every day with cherry picked weather reports and no one counters them? It’s a battle with no point. tldr; DNFTT ---

> [@watchwolf49](#): > > I do see your point here, however I think your assumption that the polar jet stream will remain in position is flawed. _Where_ the jet stream sets up depends on _where_ the polar front is. If the polar front expands toward the equator, then the jet stream will also move toward the equator. Another problem is with the 2[sup]nd[/sup] Law of Thermodynamics. Air on the temperate side of the polar front is warmer, thus contains _more_ energy than the air on the polar side. Any transfer on energy _must_ move from the temperate side _to_ the polar side. This includes the cubic miles of convective transfer, warm air moving across the front to the cold side. I’m sure there is a measurable convection effect, but I think it is just a thin layer of icing on the cake of jet stream arctic air transfer. The polar air mass expands by about 37,000 cubic miles per mile of depth per degree Celsius. Sure, that’s a lot of air, but in terms of latitude advance of the polar front, it has little effect. It amounts to pressure that squeezes the jet stream between the arctic and temperate sides of the polar front. This pressure simply forces cold air into the jet stream, whisked away at high velocity to be deposited somewhere else. Temperate side, arctic side, I bet the mix is about half-and-half, but either way we are talking about cold air. The jet stream doesn’t really move much. It gets more cold air forced into it. Its current trajectory seems to trace from the arctic to the North American cooling zone, so… > [@](#): > > 1] Watchwolf > 2] Black if available, otherwise Green 😕 > [@](#): > > 3] For the Northern Hemisphere, air in the temperate zone generally moves south to north at the surface, air in the polar zone moves north to south. Where these two air flows meet, they have no choice but to move upwards. Something about these air masses having greatly differing densities causes a weather front to develop between the two air masses, thus very little mingling. Once they reach the tropopause, they split apart again with the temperate air heading south and the polar air heading north. The jet stream sets up near the tropopause on the temperate side of the polar front. Thusly moving the polar front will indeed move the jet stream. Remember that the Arctic Polar Front looks very chaotic, whereas the Antarctic Polar Front is very regular. One is mostly over land, the other mostly over water, and the Antarctic Front more clearly shows these processes. Noteworthy here is the northern polar front on Saturn. This has been observed to form a regular hexagon, which AFAIK remains inexplicable. So it’s fair to say some of the details here are fuzzy to _everyone_ … just saying … Interesting, and I admit that I am no foremost jet stream expert by a long shot, but my proposition is ‘cold air pressed into the jet stream’, not ‘convection changing the temperature of the jet stream’. > [@](#): > > I guess all that’s left is making some Pit-worthy statement about your personal hygiene, but I’m drawing a blank. So I’ll stick with a more general Pit-worthy comment: I’m told humans taste worster than they smell, which I quite frankly find _extremely_ hard to believe.

Its current trajectory seems to trace from the arctic to the North American cooling zone, so … You seem to have the basic concept down and for the most part all the details correct. I’ve yarded up some diagrams to help us both clarify what is going on. This first one shows [two different polar jet stream configurations](http://scijinks.jpl.nasa.gov/polar-vortex/) of the many many that could be. The actual polar front would be just an RC hair north of the jet stream. Remember, this jet stream is a feature on the temperate side of the polar front, it doesn’t really cross over ever … (Hold on … HEY … are you trying to make me say something I shouldn’t … you ARE trying … why you cat-lover … I can’t believe you’ve cornered me like this … of all the low-down, despicable, sneaky snaky … you _must_ be a Canadian lawyer … fine … dammit dammit dammit) … because the polar front is a _ **physical barrier** _ to air flow … (That hurt me to say, hurt me [BAD](http://boards.straightdope.com/sdmb/showpost.php?p=18634115&postcount=4708) … I hope you’re happy now … excuse me while I wash my mouth out with bleach) … albeit a rather imperfect one. Some polar air would leak across in the scenario we’re working with, but it’s so little at a time it would quickly be warmed to the jet stream temperatures. There’s no ability of the polar air to stay together and be deposited over, say, the British riviera. More insidious would be these “lobes” of the polar front extending far far to the south. We’ve seen in recent years that even Atlanta, GA, is subject to polar air intrusions. Under the conditions of normal GW theory, we’d have a more energetic atmosphere which could indeed provide for more of these intrusions. This means we’ll not find evidence for AGW theory here, this is all normal and expected and there’s absolutely _nothing_ about elevated CO[sub]2[/sub] concentrations that would effect this. > [@Try2B\_Comprehensive](#): > > you dog!

No, elevated CO2 would encourage this phenomenon.

Do you feel better now that I’ve copped to that, cat-hater? But the warming trend seems to have sharply accelerated in correlation with the Industrial Revolution, that is, in step with man-made increases in atmospheric CO2 concentrations. So. Temperature increases attributable to man’s contribution to CO2 levels will create the ‘more energetic atmosphere’ that results in these events. I’m not saying you are altogether wrong, I’m saying we are both pointing to causes of this phenomenon, natural _and_ man-made.

ETA: but really I was just talking about cold air being pressed into the jet stream. The polar vortex seems too large an effect to be wholly caused by AGW. Encouraged? Yes. Magnified? Sure. Wholly caused by AGW? Seems like a natural phenomenon to me, one that is _nudged_ by AGW (and nudged more all the time the greater the delta T starting… now!) It’d be interesting to solve the problem of how much more polar vortex we get because of nudging from AGW. ---

I introduced [an Asimov essay](http://chem.tufts.edu/answersinscience/relativityofwrong.htm) early on in the topic, and not a single person responded to it, much less showed any possibility they understood any of it. Certainly only a very few write as if it has meaning, not that it matters in any case. > [@FXMastermind](#): > > from [The Relativity of Wrong](http://chem.tufts.edu/answersinscience/relativityofwrong.htm) > By Isaac Asimov It’s the source of the great sentiment, “John, when people thought the earth was flat, they were wrong. When people thought the earth was spherical, they were wrong. But if you think that thinking the earth is spherical is just as wrong as thinking the earth is flat, then your view is wronger than both of them put together.” Was he right about that? Such a question is only answered by an individual, by your own mind. Nobody can tell you that’s true, and force you to believe it. You have to realize for yourself the meaning of it, there is no scientific experiment, no cite, no evidence to point to, no double blind study or consensus science. And if somebody disagrees with that, there is no way to convince them otherwise. Asimov goes on to say a lot more, like > [@](#): > > The basic trouble, you see, is that people think that “right” and “wrong” are absolute; that everything that isn’t perfectly and completely right is totally and equally wrong. Which was one of the points I thought important in a science discussion, about something as contentious as global warming. When Asimov writes > [@](#): > > However, I don’t think that’s so. It seems to me that right and wrong are fuzzy concepts, and I will devote this essay to an explanation of why I think so. he is speaking to a critic of science and our current understanding. It’s an answer to the idiot view that because we don’t know everything perfectly, we don’t know anything. This idiot belief shows up in climate science, and definitely rears it’s idiot head when it comes to recent temperature data. This essay is from The Skeptical Inquirer, Fall 1989, Vol. 14, No. 1, Pp. 35-44 While he is speaking about the old “flat earth” belief system, and the ancients and such, it’s also pretty valid for measuring global temperatures, and how our view of the earth has changed. For example, the jet streams. As with most everything that comes up, it was mentioned and a source provided long ago in the thread. > [@FXMastermind](#): > > You can check the jet stream yourself, [http://squall.sfsu.edu/crws/jetstream.html](http://squall.sfsu.edu/crws/jetstream.html) and see that there is almost never a straight west to east jet stream There is this idiot belief that the “jet stream” is a single entity, a “thing”, and that it has some sort of stable structure, and exists for some reason, by itself. This is possibly due to the idiocy spewed forth by talking heads on the weather channel, where they describe it as “the jet stream”, and attribute qualities to it as if it controls the weather somehow. The link still provides the easy ability **to see for yourself** that this is just not true.

Here’s [a summer time view](http://virga.sfsu.edu/archive/jetstream/jetstream_norhem/1508/15080612_jetstream_norhem.gif). If you look at those and compare them and think, “There isn’t much of a jet stream in summer”, then you now know more than most people in the world do. The jet streams are caused by large differences in air temperature, where warm tropical air meets cold polar air. It’s why the south pole always has strong jet streams, [even in the austral summer](http://virga.sfsu.edu/archive/jetstream/jetstream_sohem/1501/15010100_jetstream_sohem.gif). It never warms up over Antarctica, even though the summer sun there is much stronger that in the north pole summer. This is because of the ice there. Lots and lots of ice. Moving on, if you [watched the video](https://www.youtube.com/watch?v=XZGsdnYqbjk#t=34) when I first linked to it, and thought “Wait a minute, that makes it sound like cold years in the arctic would have mild winters, while the years with extreme cold are from it being warmer up near the poles”, which is stupid and nobody would ever say that. Right? Ah, that’s enough of that. ---
