This is happening now.
In the United States we are well aware of the dramatic winter storms that have plagued the central and eastern areas of the nation ... that is after all where major media is headquartered.
In the rest of the country and around the world, manifestations of climate change are also evident in weather events. Weather isn't climate, but tracking, recording and analyzing what is going on now is how global warming is scientifically verified and validated.
January 2014 was remarkably mild across nearly all of Alaska. The same high-pressure system responsible for the intensification of drought in California and Oregon kept southerly winds aloft for most of the month. (A similar pattern warmed the state in October, as well.) This influx of warm air kept temperatures above normal across the state, resulting in this January ranking among the “top ten” warmest on record for many Alaskan communities according to preliminary analyses.
