Warm-up

Global warming is the world's most serious enviro problem. According to the author (see URL) global warming is responsoble for a reduction of the Arctic sea ice thickness and overall surface area by 25%. With less area of reflective ice, the darker water in the exposed areas absorbes more heat and in turn warms the water and melts more ice. This cycle will continue to raise the world's water levels to such levels that inland agricultural areas may become flooded, and more growing areas will be lost.
