Not 97% but .3% of Climatologists agree.

jem, I thought you already knew how CO2 acts like a thermostat and vehemently argued the point. Why the sudden ignorance?


"When carbon dioxide increases, more water vapor returns to the atmosphere. This is what helped to melt the glaciers that once covered New York City," said co-author David Rind, of NASA's Goddard Institute for Space Studies. "Today we are in uncharted territory as carbon dioxide approaches 390 parts per million in what has been referred to as the 'superinterglacial.'"

"The bottom line is that atmospheric carbon dioxide acts as a thermostat in regulating the temperature of Earth," Lacis said. "The Intergovernmental Panel on Climate Change has fully documented the fact that industrial activity is responsible for the rapidly increasing levels of atmospheric carbon dioxide and other greenhouse gases. It is not surprising then that global warming can be linked directly to the observed increase in atmospheric carbon dioxide and to human industrial activity in general."

Hey GWB. Got a group shot of you, jerm and luc.

No, you are confused as usual. It is you who is denying the solid common sense science that has overwhelming consensus among the science community so it is you who is the idiot. No doubt

It must be time for you to take your meds. Before they wheel you away from the computer keyboard.

CO2 is, by various estimates, responsible for 10 - 24% of the immediate greenhouse effect and and a much larger factor of long term temperature regulation of the earth right? The level of CO2 in the atmosphere are analogous to the setting on a thermostat.

Says you, perhaps. The age of the earth is approximately 4.25 billion years. You're looking at the last 100 or so years of CO2 and saying it affects warming of the earth. Just because you throw numbers around like 10-24% doesn't mean anything to me. Where's the study showing this effect on a geological timeframe? How do we know there aren't other forces at work here?

Yes, I did, because there were so many of these threads that it was cluttering up the forum. Would you like me to put you back on ignore? Are my questions too difficult or disturbing to you?
 
from you quote...

"The climate forcing experiment described in Science was simple in design and concept -- all of the non-condensing greenhouse gases and aerosols were zeroed out, and the global climate model was run forward in time to see what would happen to the greenhouse effect. Without the sustaining support by the non-condensing greenhouse gases, Earth’s greenhouse effect collapsed as water vapor quickly precipitated from the atmosphere, plunging the model Earth into an icebound state -- a clear demonstration that water vapor, although contributing 50 percent of the total greenhouse warming, acts as a feedback process, and as such, cannot by itself uphold the Earth's greenhouse effect.

"Our climate modeling simulation should be viewed as an experiment in atmospheric physics, illustrating a cause and effect problem which allowed us to gain a better understanding of the working mechanics of Earth’s greenhouse effect, and enabled us to demonstrate the direct relationship that exists between rising atmospheric carbon dioxide and rising global temperature," Lacis said."



and another recent study on water vapor which I have linked to on this thread show that water vapor .. particularly low clouds reflecting the suns energy back out can be cooling the earth not warming it.

That fact call in to question this whole idea that co2 can amp its effect...

if co2 works by adding clouds... there is strong chance more co2 cools.

now you are starting to understand the science fc.


Quote from futurecurrents:

Without non-condensing greenhouse gases, water vapor and clouds would be unable to provide the feedback mechanisms that amplify the greenhouse effect.

A companion study led by GISS co-author Gavin Schmidt that has been accepted for publication in the Journal of Geophysical Research shows that carbon dioxide accounts for about 20 percent of the greenhouse effect, water vapor and clouds together account for 75 percent, and minor gases and aerosols make up the remaining five percent. However, it is the 25 percent non-condensing greenhouse gas component, which includes carbon dioxide, that is the key factor in sustaining Earth’s greenhouse effect. By this accounting, carbon dioxide is responsible for 80 percent of the radiative forcing that sustains the Earth’s greenhouse effect.

No, not me says, science. You should try and look at it some time.

You can start here.....if you had been reading my posts you would know this stuff by now.

But I'm glad you took me off ignore?

Yes CO2 is an important greenhouse gas and we have raised it's levels by 40%.
