Some wild weather blamed on warming

WASHINGTON — A study of a dozen of 2012’s wildest weather events found that man-made global warming increased the likelihood of about half of them, including Hurricane Sandy’s devastating surge and the blistering US summer heat.

The other half — including a record wet British summer and the US drought last year — simply reflected the random freakiness of weather, researchers with the US National Oceanic and Atmospheric Administration and the British meteorological office concluded in a report issued Thursday.

This is the second year that NOAA and the British meteorology office have teamed up to look at the greenhouse gas connection to the previous year’s unusual events.
