scientists agree the Earth will be hotter by the end of the
century, but their simulations don't agree on how much. Now a
new study published in the journal Science suggests the gloomier
predictions may be closer to the mark.   That means the world
could be in for a devastating increase of some eight degrees
Fahrenheit by 2100, resulting in drastically higher seas,
disappearing coastlines and more severe droughts, floods and
other destructive weather.   Climate scientists around the world
use supercomputers to simulate the Earth's atmosphere and
oceans. Sophisticated programs attempt to predict how climate
will change as society continues burning coal, oil and gas, the
main sources of heat-trapping gases such as carbo
