NEW Evidence Of Global Warming Stumps Sceptics

LONDON, May 7. -
Powerful new evidence for global warming has been discovered
by scientists funded by the US government, demolishing the chief argument of sceptics who deny that the phenomenon is real.
A new analysis of satellite data has revealed that temperatures in a critical part of the atmosphere are rising much faster than previously thought, strengthening the scientific consensus that the world is warming at an unnatural rate.
The discovery resolves one of the most contentious anomalies in climate science, which has often been invoked by the Bush administration to questions whether man-made global warming is happening.
While it is generally accepted that surface temperatures are increasing by an average of 0.17 degrees Centigrade per decade, satellites have been unable to detect a parallel trend in the troposphere — the lowest level of the atmosphere, extending 10 km above the ground, in which most weather occurs.
This lack of tropospheric warming has long puzzled scientists, as it is predicted by all the major models of climate change. It has also been seized on by a small but vocal minority of scientists, who have used it to raise doubts about whether global temperatures are rising at all. The enigma, however, has now been explained by a team led by Dr Qiang Fu, of the University of Washington in Seattle.
