Newsflash Greenhouse gasses actually cool the atmosphere.
How big is this Greenhouse effect which has dominated our lives? About 1 watt/m2 or maybe -1 w/m2? Out of a total 340 w/m2 from the sun.
The error bars for reflective aerosols and forced cloud changes is 1.1 w/m2! Co2 effect is maybe 1.3 w/m2. This is hard to measure although they said they did with satellites in Alaska. Probably BS.
And where the NIFLHEIM is water vapor on the graph below! It accounts for 5x or I heard 60% of the warming. This negation also happened in my paleoclimatology class. If someone else sees something else in the graph let me know. I Hope all this website is wrong.
Svente Arrhenius proposed the GHG Theory and it was immediately rebuked by Knut Ångström.
Could this happen again? Yes it already did.
It’s true that water vapor is the largest contributor to the Earth’s greenhouse effect. On average, it probably accounts for about 60% of the warming effect.
There is also a possibility that adding more water vapor to the atmosphere could produce a negative feedback effect. This could happen if more water vapor leads to more cloud formation. Clouds reflect sunlight and reduce the amount of energy that reaches the Earth’s surface to warm it. If the amount of solar warming decreases, then the temperature of the Earth would decrease. In that case, the effect of adding more water vapor would be cooling rather than warming. But cloud cover does mean more condensed water in the atmosphere, making for a stronger greenhouse effect than non-condensed water vapor alone – it is warmer on a cloudy winter day than on a clear one. Thus the possible positive and negative feedbacks associated with increased water vapor and cloud formation can cancel one another out and complicate matters. The actual balance between them is an active area of climate science research.
C02 is a radiative gas and in the upper atmosphere the trace gas ejects heat into space.
If this was 1991 I could say all this in the New York Times and no one would bat an eye.
Marjorie McGuirk it also says Dr. William A. Nierenberg, a geophysicist who is director emeritus of the Scripps Institution and who has expressed doubt that global warming will be as severe as some scientists have predicted. A number of feedbacks might act to limit global warming, he said. “In fact,” he said, “the average global temperature change could be almost zero” because of the many feedback mechanisms. But the operation of the mechanisms could nevertheless impose a “severe” price in terms of the regional climate changes they would cause.
It goes on to say
Some scientists say the Ramanathan-Collins findings could lead to better predictions about the extent of the expected global warming. The predictions rest largely on computerized mathematical models of the climate system that all scientists agree are crude and flawed. One of the major flaws has to do with the effect of clouds.
