Global Warming:

Paris, 2 Feb 2007 -- The world's climate scientists today reported unequivocally that the Earth's climate system is increasingly heating up and that it likely has not been this warm for at least 1300 years. The fourth report of the UN's Intergovernmental Panel on Climate Change says that evidence for this includes more than increases in global average air and ocean temperatures.

As has been reported on this site, heating effects are strong in melting of snow and ice, rising global mean sea level, widespread changes in precipitation amounts, ocean salinity, wind patterns and aspects of extreme weather including droughts, heavy precipitation, heat waves and the intensity of tropical cyclones.
