It is good to see scientists adjust thier theories to acomodate the findings of new research.
Only a few “scientific facts” are immutable and indiputable:
1 - Global Warming is taking place
2 - It is manmade
3 - It is killing the planet - maybe even the entire galaxy
4 - The only way to stop it is to make working Americans pay higher taxes

Global warming is manmade, in the mind’s of tree-huggers, politicians, and scientists who are created the scare in order to milk tax dollars.
