While many people in the media and scientific community claim the climate change science is settled, do the facts back that up? Derisively called "deniers," climate change skeptics continue to challenge the so-called conventional wisdom, asking "Is global warming a hoax? Is man-made global warming the dire threat environmentalists claim?"
Recent global warming agreements brokered by the U.N. seek steep reductions in world C02 output to slow the presumed warming of the earth's atmosphere, while also seeking alterations in the economy that would move energy sources away from fossil fuels toward renewable natural energy.
