"Extreme weather events over the past decade have increased and were 'very likely' caused by manmade global warming, a study in the journal Nature Climate Change said on Sunday."
"Scientists at Germany's Potsdam Institute for Climate Research used physics, statistical analysis and computer simulations to link extreme rainfall and heat waves to global warming. The link between warming and storms was less clear.
'It is very likely that several of the unprecedented extremes of the past decade would not have occurred without anthropogenic global warming,' said the study.
The past decade was probably the warmest globally for at least a millennium. Last year was the eleventh hottest on record, the World Meteorological Organization said on Friday."
