Are you drunk? You don't even know what you are talking about. Go sleep it off and quit making me laugh at your stupidity.
Water vapor and clouds are the major contributors to Earth's greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet's temperature ultimately depends on the atmospheric level of carbon dioxide.

The study, conducted by Andrew Lacis and colleagues at NASA's Goddard Institute for Space Studies (GISS) in New York, examined the nature of Earth's greenhouse effect and clarified the role that greenhouse gases and clouds play in absorbing outgoing infrared radiation. Notably, the team identified non-condensing greenhouse gases â such as carbon dioxide, methane, nitrous oxide, ozone, and chlorofluorocarbons â as providing the core support for the terrestrial greenhouse effect. Without non-condensing greenhouse gases, water vapor and clouds would be unable to provide the feedback mechanisms that amplify the greenhouse effect. The study's results will be published Friday, Oct. 15, in Science. 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. http://www.giss.nasa.gov/research/news/20101014/
Old info from 2010. And, global satellite temps for the last 17 years show their conclusions to be wrong. Get a grip. How many times do you have to be shown that "it's the sun, stupid"? You're drunk anyway. If your not, you're even more stupid than I thought you were. AGW is bunk! http://drtimball.com/2011/why-is-water-vapour-the-most-important-greenhouse-gas-ignored/
Futurecunt. He isn't making any sense. Of course, he never did. Thomas Huxley said, âThe great tragedy of science â the slaying of a beautiful hypothesis by an ugly fact.â The hypothesis that human CO2 is causing warming is slain because they essentially ignored the role of water vapor in the atmosphere, but when used, it was done incorrectly. Of course, none of this speaks to clouds, the other major water problem in the atmosphere for the global warming hypothesis and computer models. Now the world is in a blind alley with energy and economic policies based on predictions from climate models that omit major elements and use false assumptions.
We see from direct observation that water vapor tends to moderate global temperatures. As Dr. Roy Spencer notes, âThe question of how much warming will result from adding carbon dioxide to the atmosphere is what we skeptics are skeptical of. The climate system is amazingly complex, and the IPCC position that elements within the climate system (especially clouds) will change in ways which amplify the resulting small warming tendency is highly questionable, to say the least. If the climate system instead acts to reduce the warming, then anthropogenic global warming (AGW) becomes for all practical purposes a non-issue.â References: Earthâs climate engine by Dr. Daniel M.

The fact is that CO2 levels have gone up 35% in the last 150 years due to man. CO2 is a greenhouse gas. How could that NOT make temps go up? It's a very simple common sense thing......... that the fossil fuel industry doesn't want you to think about. The science is settled. 97% of the world's climatologists and all the world's science organizations are in agreement about it. The deniers just look foolish now.
Even Russian scientists are saying we are going to experience a huge cooling cycle due to a drop in solar output. --- âWe could be in for a cooling period that lasts 200-250 years. The period of low solar activity could start in 2030-2040.â Global warming which has been the subject of so many discussions in recent years, may give way to global cooling. According to scientists from the Pulkovo Observatory in St.Petersburg, solar activity is waning, so the average yearly temperature will begin to decline as well. Scientists from Britain and the US chime in saying that forecasts for global cooling are far from groundless. Some experts warn that a change in the climate may affect the ambitious projects for the exploration of the Arctic that have been launched by many countries. Just recently, experts said that the Arctic ice cover was becoming thinner while journalists warned that the oncoming global warming would make it possible to grow oranges in the north of Siberia. Now, they say a cold spell will set in. Apparently, this will not occur overnight, Yuri Nagovitsyn of the Pulkovo Observatory, says. âJournalists say the entire process is very simple: once solar activity declines, the temperature drops. But besides solar activity, the climate is influenced by other factors, including the lithosphere, the atmosphere, the ocean, the glaciers. The share of solar activity in climate change is only 20%. This means that sunâs activity could trigger certain changes whereas the actual climate changing process takes place on the Earthâ. Solar activity follows different cycles, including an 11-year cycle, a 90-year cycle and a 200-year cycle. Yuri Nagovitsyn comments. âEvidently, solar activity is on the decrease. The 11-year cycle doesnât bring about considerable climate change â only 1-2%. The impact of the 200-year cycle is greater â up to 50%. In this respect, we could be in for a cooling period that lasts 200-250 years. The period of low solar activity could start in 2030-2040 but it wonât be as pervasive as in the late 17th centuryâ. http://www.thegwpf.org/we-cooling-period-lasts-200-250-years-russian-scientists-claim/ <img src=http://static5.businessinsider.com/image/4d935896cadcbbb437490000/global-cooling.jpg> <img src=http://t1.gstatic.com/images?q=tbn:ANd9GcRCQ-HWvH68-4s4bbeDzs9iyoq_i19b3k_eHDBBYo5_n6S1eJse>
