"The results, nevertheless, were striking. In the parts of the spectrum absorbed by carbon dioxide, ozone and methane, the amount of longwave radiation escaping from earth dropped sharply between 1970 and 1997—and did so in a way that matched predictions based on the known increases in levels of those gases. A weaker, but similar, effect was seen for CFCs." The Economist 15 Mar 2001
More comprehensive data is expected in future studies. Much of the data available from IMG was eliminated becase IRIS did not measure those same paramters. But still the results were so striking - strongly confirms other data on global warming and provides absolutely nothing to indicate that global warming is not happening. Global warming is indisputable among those who don't use emotion to create their conclusions. The only part in dispute is the speed of global warming - and it is significant. See this chart from The Economist of 16 Nov 2000.
The above chart demonmstrates that greenhouse gases historically do create the greenhouse effect - for the past 400,000 years AND that the recent temperature climb is sharper, unprecidented, and significantly greater (overwhelmingly more significant) than any time in the past 1000 years. The greenhouse effective is proven, is a world wide problem, and is only denied by those who have opinion but cannot cite facts to prove those opinions.
