Quote from jem:
you science denying troll.
..
Nasa says
a. co2 is a thermostat
b. science does not know if more aerosols warm or cool.
c. does not know if adding water vapor (clouds) net warms or cools.
So what you say?
You really are an ignorant troll if you do not understand that greenhouse gases act to keep warmth in and warmth out.
and NASA does not know the net effect.
"jem......you ignorant slut"
a. NASA does NOT say CO2 acts as thermostat. ONE NASA scientist erroneously used the term. He used the term wrongly and the thermosphere - what he was talking about - has essentially nothing to do with AGW. That you do not understand this or refuse to acknowledge it is troubling and suggests that you may be either in denial or purposefully lying.
b. Science knows aerosols in the stratosphere cool the earth. Aerosols in the lower atmosphere have less net effect. The use of high altitude aerosols has been suggested as a way to cool the earth. At any rate, it again has little to do with CO2/AGW and it's current warming of the lower atmosphere.
c. " The scientific majority believes that clouds will most likely have a neutral effect or will even amplify the warming, perhaps strongly, but the lack of unambiguous proof has left room for dissent.
âClouds really are the biggest uncertainty,â said Andrew E. Dessler, a climate researcher at Texas A&M. âIf you listen to the credible climate skeptics, theyâve really pushed all their chips onto clouds.â
Richard S. Lindzen, a professor of meteorology at the Massachusetts Institute of Technology, is the leading proponent of the view that clouds will save the day. His stature in the field â he has been making seminal contributions to climate science since the 1960s â has amplified his influence.
His idea has drawn withering criticism from other scientists, who cite errors in his papers and say proof is lacking. Enough evidence is already in hand, they say, to rule out the powerful cooling effect from clouds that would be needed to offset the increase of greenhouse gases."

Here's what NASA says about clouds...
"Most climate models predict that clouds will amplify global warming slightly. Some observations of clouds support model predictions, but direct observational evidence is still limited. Clouds remain the biggest source of uncertainty (apart from human decisions to control greenhouse gas emissions) in predicting how much global temperatures will change."

Jem, you're doing a good job of misdirection, obfuscation, inflation, misrepresentation and deception. Right from the playbook.
I think that the American Geophysical Union might know about this stuff, and they say the following...
"The Earth's climate is now clearly out of balance and is warming. Many components of the climate system â including the temperatures of the atmosphere, land and ocean, the extent of sea ice and mountain glaciers, the sea level, the distribution of precipitation, and the length of seasons â are now changing at rates and in patterns that are not natural and are best explained by the increased atmospheric abundances of greenhouse gases and aerosols generated by human activity during the 20th century."
