LONDON, March 5 (UPI) — Evidence of manmade global warming is stronger than the besieged U.N. climate panel claimed, with rainfall changes altering the Earth, British scientists said.
“The fingerprint of human influence has been detected in many different aspects of observed climate changes,” Peter Stott, head of climate monitoring at the Hadley Center for Climate Research run by Britain’s meteorological office, said in remarks quoted by the Financial Times. “Natural variability, from the sun, volcanic eruptions or natural cycles, cannot explain recent warming.”
Stott spoke on behalf of an international research team, led by Britain’s Met Office, that analyzed more than 100 scientific papers to update the U.N. Intergovernmental Panel on Climate Change’s 2007 report.
The 2007 report seized worldwide attention after asserting human activity was warming the planet in ways that could greatly disrupt human affairs and nature.
The panel, which won a Nobel Peace Prize for its report, is now accused by climate skeptics, conservative politicians and some mainstream scientists of scientific sloppiness and potential financial conflicts of interest.
The latest review, published in the journal Wiley Interdisciplinary Reviews: Climate Change, pointed to human-made warming evidence that was not clear in 2007.
This includes climate change in the Antarctic, which covers some 20 percent of the Southern Hemisphere and is the last continent where regional warming has been demonstrated, the research review said.
The subtropical Atlantic Ocean is also becoming warmer and saltier, which could modify ocean currents, the research suggested.
The ocean warming is also increasing evaporation, boosting humidity in the atmosphere and changing rainfall patterns. This means less rainfall in the tropics and more at higher latitudes, the Financial Times cited Stott as saying.
