New U.S. Geological Survey Report is Sobering
A new report from the U.S. Geological Survey states that the United States faces the possibility of a much faster climate change by the end of the century than what earlier studies have indicated.
Satellite data over the past two years shows the world's major ice sheets melting much more rapidly than previously thought, and based on this new information the global sea level rise by 2100 could be as much as 4 feet, according to the report. The earlier report from IPCC estimated a 1.5 foot sea level rise by 2100, but that report did not factor in the lubrication under the ice sheet.
The other major point of this new report was that the Southwestern U.S. may have already entered a prolonged drought that could extend all the way to the end of the century. Nearly all of the 24 computer models that were used in this study showed this long term drought.
------------------------------------------------------------
But, the report also indicated that were also some global warming effects that are NOT likely to occur by 2100........
--An abrupt release of methane from the seabed and permafrost.
--A shutdown of the Atlantic Thermohaline Circulation, which brings warm water north and colder water south.
Thirty-two scientists from federal and non-federal institutions contributed to the report, which took nearly two years to complete. The Climate Change Science Program, which was established in 1990, coordinates the climate research of 13 different federal agencies, according to the Washington Post Article.
