Global Warming
Global warming is the warming near the earths surface that results when the earths atmosphere traps the suns heat. ... Global warming will affect weather everywhere, plants and animals everywhere, people everywhere; humans are warming the earths atmosphere by burning fuels, cutting down forest, and by taking part in other activities that release certain heat trapping gases into the air.
One major cause of global warming is the use of fossil fuels. ... The degree of change depends on the degree of global warming. ... Global circulation models have shown that warming will be faster near the poles than near the equator. ...
Another major effect of global warming is the rising of seas. ... According to theory, global warming could cause thermal expansion of the ocean waters, which in turn would cause sea levels to rise. ... Because global warming is expected to be greatest in polar and temperate regions, scientists expect the glaciers to melt more rapidly than they do today. An executive summary of a United Stations survey published in 1990 concluded that if worldwide "business as usual" continues, the resulting global temperature increased would produce mean sea-level rise of about twenty-five inches by the end of the next century. ... If global warming accelerates and the ice melts faster than expected, ocean levels may rise as much as ten feet by 2100.
In order to slow global warming, scientists estimate that we need to cut in half the amount of carbon dioxide that we now release into the air each year. ... If we really want to control the greenhouse effect and global warming, then people everywhere must learn to use energy more wisely. ... Most importantly, energy conservation will reduce carbon dioxide in the atmosphere and slow the rate of global warming. ... But reforestation on a smaller scale can at least help slow the buildup of carbon dioxide in the air and delay global warming. ... Like conserving energy, planting trees is a way in which many people can become involved in helping to control the greenhouse effect and global warming. ...
If we can reduce the greenhouse gases going into the atmosphere, we probably can slow the rate of global warming and climate. ... As global warming alters habitats, many kinds of animals will be on the move, but all sorts of barriers will stand between them and a new place to live. ... It is a global, problem, one that must be faced by people everywhere. No nation acting alone will be able to slow the pace of global warming due to climate change.
