The article at realclimate appears to describe an atmospheric warming effect that doesn't involve back-radiation. More absorption, conduction.

On that basis, CO2 in isolation could produce some warming, which also warms water vapour in the air. What is missing is the negative feedback effect of clouds.

Lindzen and Choi paper describes the negative feedback effect of clouds as determined buy their analysis of satellite data:

Thanks for the link. A very interesting read. After over twenty years of expensive research you would think we would have some definitive numbers for AGW that nobody can argue about.

Possible long-term consequences of the “greenhouse effect,” the gradual warming of the Earth’s climate, may include melting the polar ice caps and a rising sea level.

A. may include melting the polar ice caps and a rising sea level

B. may include the melting of polar ice caps and the rising sea level

C. may include polar ice caps that are melting and sea levels that are rising

D. include melting the polar ice caps and sea levels that are rising

E. include melting of the polar ice caps and a rise in sea level

No the greenhouse effect is genuine. Because of the backradiation, the surface temperature and the upwards thermal radiation is much larger than if there was no greenhouse effect.

Atmospheric backradiation has been directly measured for over fifty years. The effects of greenhouse gases stand out clearly in modern measurements, which are able to show a complete spectrum.


Coincident measurements of the infrared emission spectrum of the cloudfree atmosphere at (a) 20km looking downward over the Arctic ice sheet and (b) at the surface looking upwards.

You can see the 'mirror image effect due to absorption at 650 and 1050 cm-1
