Global Warming. What the Scientist’s point to.

Global Warming. How do the scientists describe it? – A gradual warming of the Earth's atmosphere reportedly caused by the burning of fossil fuels and industrial pollutants. An increase of the earth's temperature by a few degrees resulting in an increase in the volume of water which contributes to sea-level rise. Strictly speaking, global warming and global cooling refer to the natural warming and cooling trends that the earth has experienced all through its history....

Global Warming. Arctic sea ice has shrunk by 250 million acres, an area the size of California, Maryland and Texas combined. This satellite image shows the Arctic sea ice spread on September 21, 2005, when it dropped to the lowest extent yet recorded. The yellow outline indicates where the concentration of ice was as of September 21, Photo: AFP

Global Warming. Heavy sea ice has been the norm in the Antarctic, but in the 1990's sea ice disintegration has begun. Robin Ross, a biological oceanographer with the University of California at Santa Barbara.
