Are you saying that the US Global Change Research Program's conclusion is irrelevant? Are you trying to say that they wasted all this research money for nothing?
No, I'm not saying this. I'm just saying that "maybe" the global warming could be a natural event. You must admit that the "US Global Change Research Program" only watch the last earth period, and for this reason it IS prominent if you study THAT period. Earth history is a lot longer.
Keep also in mind that USGCRP shows a fact: the global warming, wich is real, but AFAIK It never tells something like: "we are absolutely shure that the global warming was caused by the human activities". It tells something like "MAYBE the impact of the human activities is relevant" wich is totally different in my opinion.
Now I have in mind the glacial eras: they were natural. After each event there was a "global warming era". It's a bit semplistic in my opinion to give an absolute conclusion watching only 150 years. Just to give you an example:
Since the 1300 and until the 1850 (just a case?) whe have seen a small glacial era. It takes about 400 years and in this period the temperature was a lot lower than the mean before and after.
This event is well documented in europe and north america. Here in europe the switzerland glaciers becamed so big to englobe farms and destroy villages.
The causes are still unknown but maybe of a great importance was the slowering of the ocean streams (like the gulf stream).
Maybe also the solar activity had its importance because it was changed in that time (there was less sunspots documented) etc...

After that, I want to say that I totally agree with who complains the U.S. decision of avoid the Kioto treaty. (a very ignorant and arrogant force exibiton in my opinion)
I totally agree on putting some tight limits to the impact of the human activity on the enviroment,
I totally agree on making more inspections on enviromental impact worldwide and I totally agree with who says that the problem is internal to our life stlyle, and to live in a better world we have to learn the respect of it.
