A recent poll reported that 74% of Americans think that climate change can be felt in their weather and almost the same percentage agreed that climate change exacerbated record high temperatures and droughts in the US summer of 2012.
Last year's very mild US winter and windstorms which blasted the US Northeast last June are also being taken into account by the general American public, according to the poll.
Another study published recently in the Proceedings of the National Academy of Sciences (PNAS) found that between 1981 and 2010 extreme heatwave events had increased by 50 to 100 times. The conclusion was that climate change was the only statistically logical explanation.
