The overwhelming consensus among climate scientists is that while
global warming is the result of both natural and artificial phenomena,
the difference in average global temperature since the late 19th
century compared to
other eras is attributed mostly to man-made
greenhouse gas emissions.
That debate IS over, and the only ones who question it are the
American right wingers who can't be bothered with science and prefer
instead to listen to the likes of rush limbaugh.
