There is no doubt that global warming is
real. According to an article in the April 2008
issue of Science, "surface temperatures have
increased 4.5ºF (2.5ºC) in the last 50 years on
the Antarctic Peninsula, the mountainous arm that
trails toward the southern tip of South America."
The question is not is it real; rather, the question is what is causing it.
