No definition, explanation or link to anything that explains the theory in that link.

No surprise there. Google search shows the terms “AGW theory”, “global warming theory”, or “theory of global warming” do not appear anywhere on the NAS website.

Neither does “CO2 theory”, “greenhouse theory”, climate theory" “climate change theory” or any combination of those.

there is nothing there. Which is exactly why GIGOGalloper won’t link to the site.

Temper tantrum precious? Naw. I just enjoy your antics.

With FX strutting about going ,“Nyuk, nyuk nyuk”, TOWP continuing to poke himself in the eye, and Aji challenged with the concept of up and down, I figure I must’ve clicked the wrong thread and got the ," Meet and greet the progeny of the Three Stooges" thread.

Once again you told us that they never tell you what is the theory they are talking about, in a summary that is talking about human made global warming. It is indeed telling that you can not identify then what on earth is the theory that they are talking about.

It’s turned into a real train ride. Hell, I ain’t even had a chance to talk about all the record cold going on right now, or why global warming sucks so bad.

what’s wrose, is that while there has no doubt been warming, the type of warming does not match what the computer models predicted. Nor has the climate change happened as the consensus declared it would.

Looking at the actual records, and they do indeed exist, it’s obvious that while warming has happened, it has not happened in the way the CO2 theory of global warming imagined it would.

In fact, and this is the real irony, it happened in a way nobody predicted. And, as current science is proposing, it isn’t CO2 that is the source of the current climate change.

This does not mean CO2 isn’t a factor, nor does it mean in the future CO2 is going to be an issue. It just isn’t right now.

Oh shit, you mean we’d only end up with cleaner air and water and a more sustainable world to live in?! Fuck that shit! I want some crude oil to dip my McNuggets in! :dubious:

Cool. So you cherry pick a couple select spots/time frames, and presto, the experts are entirely WROSE!

Dunno YogSosoth. Sure you can point to the 97% to 98% of the people who study climatology for their livlihood agreeing the worlds warming and man’s activities are responsible.

But there’s four slapdicks here with the impressive credential of being interwebz posters who are telling us it just ain’t so. I find the slapdicks convincing even if they can’t present an argument in a coherent, consistent, non-contradictory manner.

I’m torn. ☹

There’s the line repeated over and over here, by the very people who claim they are not posting for the foolish deniers, but for the other people, who want to learn.

Yet they excuse themselves from being bothered with any science, because the fools will deny it.

It’s a goddamn religion. A crazy ass one to boot.

Even if you want to avoid calling a theory (who knows why?) you can call it CO2 based warming. You can easily explain or link to) what this means, how it works, what will happen, why it’s a serious issue.

But instead we see endless boring posts concentrating on insults and claims you already did everything.

Priceless.

If I was trying to tear your religion apart, I don’t need to actually write anything to make you look bad. You got it covered.

The physics of CO2 based warming theory are simple, the signatures to tell it’s happening are simple to explain, and the evidence for each signal are easy to come by.

It’s why you don’t do this, that’s the comedy gold.

Since the warmists just won’t do it, I’m tempted to explain (to them, oh the irony) what it is they are avoiding discussing.

Water vapor (WV) is the main greenhouse gas. CO2 theory claims any warming caused by changes in atmospheric CO2 leads to an increase in WV. This means temperature is controlled by changes in CO2.

WV in the atmosphere is a function of temperature. The Clausius-Clapeyron relation means warmer causes more WV.  
WV is theorized to amplify CO2 warming, and a doubling of CO2 is theorized to warm the globe around 1°C. WV is theorized to double the amount of CO2 warming. Assumptions about albedo changes due to doubling of CO2 is theorized around 3°C

Atmospheric drying observed due to volcanoes is theorized to cause global temperatures to drop, due to lower WV levels.

Climate models based on this theory show the increase in CO2 caused by the burning of fossil fuels is the reason for any increase in WV.

AGW Theory claims the increase in water vapor is around 6 to 7.5% per degree Celsius warming of the lower atmosphere.

And that is a simple explanation of global warming theory, or AGW theory.

You know in your heart it is true.

The signatures of CO2 theory are just as simple, and anyone with even a casual study of global warming could list them in their next post.

These are the things the theory says will occur, and how we can know it is CO2, and no other type of warming.

That nobody has listed them yet, that is fucking hilarious.

I very much doubt any of the oh-so-concerned parties will ever do this.

Just like my last several predictions came true, this one is also a lock.

First: I’ll quote myself. Tell me if there is anything wrong with any of these using the invented data I provided.

Second: Do you accept that I’ve \*\*never \*\*mentioned a downturn (i.e. temperatures going down), even less a prolonged downturn, but a recent flattening (temperatures remaining the same) of average temperatures?  
Of ocurse, if you mean that the second derivative of the equation graphing the average temperatures in shor time-periods became negative in the recent present and you mean by THAT a prolonged downturn then it could be a problem of nomenclature.

Third: Please tell me if anything I say here and that I accept as true, contradicts the [NASA chart](http://www.nasa.gov/images/content/616910main_gisstemp_2011_graph_lrg%5B1%5D.jpg)you mention.  
(I’ll use the red line of 5-year mean as a base)

- Temperatures on average have increased form the 1880s to 2011 about 0.8-0.9°C
- \*\*Nowhere in the chart is there a prolongued \*\*(more than a decade) \*\*downturn \*\*(decrease) of temperatues.
- There is a decrease of 0.2°C from about 1900 to about 1910
- There is a decrease of 0.2°C from about 1940 to about 1950
- Neither of the provious two qualify as prolongued downturns.
- If we trace a line from the the point where the red line meets the uncertainty bar just after 2000 and connect it with the point at the end (called 2011 +0.51), that line would have a slightly negative slope. I’ll accept it’s cherry-picking, but the line, albeit maybe not statistically significant, exists.
- This line is not a prolongued downturn.
- If you draw a line connecting the lowest point of the line about 1910 and connect it the highest point just after 1940 this line has a slope that is very similar to the one you would get if you traced a line from the lowest point before 1970 and trace it to the point in 2011.
- This coincidence of slopes can be a purely mathematical artifact or could be an interesting scientific point.

That’s it.

Quite likely if you offer your own definition, you will be accused of setting up a strawman.

I have offered the following definition:

> [@](#):
>
> that CO2 emissions will cause temperatures to increase, which will increase levels of water vapor, which will cause further temperature increases, etc. etc., until a point where there are serious negative consequences to mankind.

The key point is that the hypothesis depends on water vapor feedback, i.e. that any warming due to CO2 (or for any other reason) will be dramatically amplified by water vapor feedback.

However there is very little evidence for the water vapor feedback hypothesis; there is not widespread agreement about it; and there is good reason to believe that it is wrong.

In several of those long ass science posts I did earlier, I laid out some of the current theory about what is happening with water vapor and albedo, and why the assumptions in the CO2 theory may be completely wrong.

Unlike the purely hypothetical assumptions used by the climate models and disastrous warming proponents, they are based on science.  
It’s physics, bitch.

Indeed the NAS document that was linked already shows why this is a serious issue, but we get from FX the lie that it was not done.

As for the not a theory/theory it was pointed beofre that there are many lines of inquiry that is telling us that AGW is happening. Each one of them has a basic theory, an attempt at humoring the denier here was done by simplyfying and looking at one of those lines in the form of the basic CO2 properties as a global warming gas, even before Plass the evidence for that line was excellent, but once again to simplify we concentrated on the basic theory that continues to be confirmed today.

All that past information and evidence has been denied.

So, so much for the simplification method, in the real complex world the pedantic reason why there is no single theory is just like the “tobacco causes cancer and other diseases”, there are many lines of research that showed how deadly it was, not a single one.

The point is that this amounts to application of a theory that emerged and reached mathematical and conceptual maturity entirely independent of worry about climate change.

The climate is not going to stay the same. It can’t stay the same. Staying the same would violate physics; specifically it would violate the law of energy conservation. Something has to change.

Further, all those lines of evidence converge pretty much about how much warming: about 2.5 C to 3C for each doubling of CO2. (It’s logarithmic in total CO2, not in emitted CO2, guys, by the way.) There’s no single line of reasoning for this. There are multiple lines of evidence.

In fact, though, they haven’t defined their terms. If the sensititivity is less than 1, is the supposed hypothesis falsified? What if it is more than 6? If the onset time is a hundred years rather than ten?

Estimates of the built-in delays (about twenty years for full effect of current concentrations). Estimates of the threshold of excessively high social risk (some range here but I go with 2 C ~ 450 ppmv).

If these numbers wobble around a bit that might shift the optimum policy a bit, but we’re so far from the optimum now that it’s not worth putting much thought into it yet. The numbers, however, are never going away. There will always be a sensitivity, a response curve, a risk threshold. If you are asking what evidence could make me believe that there are no such numbers, I can’t actually imagine it.

And it has to be observed that this line of attack regarding if there is an specific theory or not is because the professional deniers of AGW are the same as the deniers of the tobacco causes cancer. Same FUD.

The theory of AGW is in reality a collection of other ones, no wonder there is a denial point to be made on demanding a definition, in reality deniers are never willing to deal with a single line of inquiry.

As for the vague arguments about past global changes, the warming before AGW takes over, there is [a set of graphics here](http://www.skepticalscience.com/climate-models-intermediate.htm) that show what the IPCC thinks happened.

The first figure, if you look at (a) you can see the assumptions about “natural” forcings that caused warming.

The irony? They are claiming all the warming came from the solar variations. And all the cooling was due to vulcanism.

So the warming is from the sun, up until the AGW takes over, clearly visible in (b)

There is a wealth of data in those two graphs.
