Quote from futurecurrents:
"Man-made climate change contributed to some of 2012's most extreme weather, including the spring and summer heat waves that baked parts of the United States and Hurricane Sandy, which devastated coastal communities along the eastern coast of the country, according to a new report.
The study, which includes research from 18 different teams from around the world, examined 12 extreme weather events from last year and found that human-caused global warming increased the likelihood of half of the incidents, while the others were dictated by naturalweather variability.
"We've got some new evidence here that human influence has changed the risk, and has changed it enough that we can detect it," Peter Stott, a climatologist at the United Kingdom Met Office, the U.K.'s national weather service, told reporters in a news briefing on Thursday (Sept. 5). "There's a great deal of variability, [but] nevertheless, we've seen evidence for that increase in risk.""

This is quite amusing because this article does NOT REFLECT WHAT THE ACTUALY REPORT SAID.
The report says that it is very difficult to associate the weather events with man-made climate change.
The clowns writing this article quote tiny pieces of the report out of context trying to make the conclusions appear 180 degrees opposite of what was stated.
Here is a link to the report - http://journals.ametsoc.org/doi/pdf/10.1175/BAMS-D-13-00085.1
