Global Warming Increaing Exponentially

Major Temperature Rise Recorded in Arctic This Year: German Scientists

PARIS - German scientists probing global warming said they had detected a major temperature rise this year in the Arctic Ocean and linked this to a progressive shrinking of the region's sea ice.

Temperatures recorded this year in the upper 500 meters (1,625 feet) of sea in the Fram Strait -- the gap between Greenland and the Norwegian island of Spitsbergen -- were up to 0.6 C (1.08 F) higher than in 2003, they said in a press release received here.

The rise was detectable to a water depth of 2,000 meters (6,500 feet), "representing an exceptionally strong signal by ocean standards," it said.

The experts, from the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven, have been recording temperatures aboard a specialized vessel, Polarstern (Pole Star), for the past six weeks.

The sampling has been taking place in the West Spitsbergen Current, which carries warm water from the Atlantic into the Arctic Ocean.

The institute said water in the Fram Strait has been warming steadily since 1990 and over the past three years, satellite images had documented "a clear recession" of sea ice edges, both in the strait and the Barents Sea.

The latest data "point towards a further warming tendency," the institute said.
In June, a UN organization announced that American scientists had detected an "alarmingly rapid growth" this year in airborne concentrations of carbon dioxide (CO2), the fossil-fuel pollutant blamed for global warming.

CO2 levels recorded in March 2004 at Hawaii measured 379 parts per million (ppm), an increase of three ppm over the previous year.

By comparison, there had been an annual increase of only 1.8 ppm over the past decade. Atmospheric concentrations of CO2 before the Industrial Revolution were 280 ppm.
