You've got to be joking.
You think there is a WORLDWIDE massive conspiracy that has the vast majority of scientists sharing the same opinion?
Bingo! I think you've got it now!
This controversy is like any other....follow the trail of money and you'll eventually get to the TRUE issue.
And to correct your statement, the VAST MAJORITY of scientist do not share this opinion. Perhaps in the sample of literature you've read this is true, but most guys who study weather patterns and climate trends for a living do NOT subscribe to man-made global warming. No one questions that there has been a slight upward trend in temperatures across the globe. It's the source of that rise that is in dispute. It is vain in the extreme to believe that humans are responsible.
