Climate change results in greater weather extremes, and an overall warming trend, but that does not mean that it will be warmer all the time everywhere. It bothers me when people say, "oh, look, last week was cold so ha ha global warming." Last year (2012) was the warmest year on record. The US is in a serious drought. The polar ice cap is at the smallest extent ever recorded. Glaciers are receeding more rapidly than anyone predicted.
And it is 45 degrees and raining here in Alaska in January. So, yeah, greater weather extremes is not the norm, not the exception now. Hurricane Sandy anyone?
