Abstract:
Global warming is the most pressing issue
facing the world today. The latest report from the
largest group of scientists ever to study an issue,
the Intergovernmental Panel on Climate Change
(IPCC), states that greenhouse-gas emissions must
peak by 2015 and decrease by 80 percent or more
by 2050 in order to avoid dramatic temperature
increases and the severe economic, social, and environmental
impact that would accompany such
increases. According to the IPCC, making this shift
requires action within the next two to three years
at all levels of society.
