"LONDON -- The cause of much of the recent extreme weather across the world is climate change triggered by human activities, scientists say. The paper suggests that man-made climate change is repeatedly disturbing the patterns of airflow around the northern hemisphere."

"The Earth has experienced a range of severe regional weather extremes in recent years, including the heat waves of 2011 in the United States and 2010 in Russia, a year that also brought the unprecedented Pakistan floods.

Behind these distinct events, though, there is a common physical cause, according to a team at the Potsdam Institute for Climate Impact Research in Germany."
