- Direct human impact is through changes in the concentration of certain trace gases such as carbon dioxide, chlorofluorocarbons, methane, nitrous oxide, ozone, and water vapor, known collectively as greenhouse gases. Enhanced greenhouse gases have little effect on the incoming energy of the sun, but they act as a blanket to reduce the outgoing infrared radiation emitted by Earth and its atmosphere; the surface and atmosphere therefore warm so as to increase the outgoing energy until the outgoing and incoming flows of energy are equal.
- Further, increases in greenhouse gases are nearly certain to produce continued increases in temperature. Such changes in temperature lead to changes in clouds, pressure, winds, and rainfall in a complex sequence of further effects.

American Meteorological Society: Incorrect Science
The American Meteorological Society has approved a new policy statement, however without changing its previous Climate Change An Information Statement:
So we have here the same IPCC mantra of an alarming "greenhouse gas effect", which we in previous posts have discovered to lack scientific basis.
