WASHINGTON — Rising temperatures caused ice to melt in Greenland at a record rate this year, climate scientists reported Monday.
Greenland is about one-quarter as big as the continental United States , and 80 percent of it is covered by a massive ice sheet. It got its name because, from about A.D. 1000 to 1300, during the so-called ``Medieval Warm Period,'' it was warm enough to support forests and thriving colonies of Viking settlers.
This year's melt lifted global sea levels about two one-hundredths of an inch, Steffen said. If the entire ice cap melted, it could raise the sea by 21 feet, swamping coastal cities and low-lying islands, but such a catastrophe isn't expected for at least a thousand years, if ever.
Steffen, who's spent 18 seasons working on the Greenland ice cap, attributed the accelerated melting to an air temperature increase of about 7 degrees Fahrenheit since 1991.
Aren't there bigger issues that may pose a more immediate threat to the human race such as nuclear war and new world order?
It isn't just global warming anymore. The warming happened over the past 50-200 years as any number of books can explain.
But it is no movie. It is the future of most hurricane seasons to come. These super hurricanes as featured in these documentaries will affect everything from insurance, home building, stock markets and investments, interest rates, unemployment, the economy, politics, land use, the environment, even opinions about Iraq war expenditures.
These summers the water gets as hot in the gulf as the satellites can record.
