Authored by Prof. David H. Douglass (Univ. of Rochester), Prof. John R. Christy (Univ. of Alabama), Benjamin D. Pearson (graduate student), and Prof. S. Fred Singer (Univ. of Virginia), the study appears in this month's International Journal of Climatology of the Royal Meteorological Society.
“The observed pattern of warming, comparing surface and atmospheric temperature trends, does not show the characteristic fingerprint associated with greenhouse warming. The inescapable conclusion is that the human contribution is not significant and that observed increases in carbon dioxide and other greenhouse gases make only a negligible contribution to climate warming," said lead author David H. Douglass.
Co-author John Christy said: “Satellite data and independent balloon data agree that atmospheric warming trends do not exceed those of the surface. Greenhouse models, on the other hand, demand that atmospheric trend values be 2-3 times greater. We have good reason, therefore, to believe that current climate models greatly overestimate the effects of greenhouse gases. Satellite observations suggest that GH models ignore negative feedbacks, produced by clouds and by water vapor, that diminish the warming effects of carbon dioxide.”

Abstract
We examine tropospheric temperature trends of 67 runs from 22 Climate of the 20th Century model simulations and try to reconcile them with the best available updated observations (in the tropics during the satellite era). Model results and observed temperature trends are in disagreement in most of the tropical troposphere, being separated by more than twice the uncertainty of the model mean. In layers near 5 km, the modelled trend is 100 to 300% higher than observed, and, above 8 km, modelled and observed trends have opposite signs. These conclusions contrast strongly with those of recent publications based on essentially the same data. Copyright © 2007 Royal Meteorological Society

whats it all about? why not condense into a summary?
Here's a paper that comes to the opposite conclusion

and a slightly technical dissection of the paper posted.

I don't know what baffles me more: the US insistence that global warming doesn't exist (as if anyone really cares) or that Alabama has a university.
Go on now, admit it.

There is nothing to explain it except old Sol acting up. Unless we choose to think that somehow the evil US has planted fart bombs on the rovers that polute the poor planet to death.😛
But the sun is a variable star. I don't know why we are astonished by it getting warmer and colder. Earth has had oceans 300 meters higher than today and 300 meters lower than today in the past million years. And not just once but dozens of cycles.
So yup. Global warming seems to follow Solar warming and Global cooling seems to follow Solar cooling. Imagine that! Like Duh!
