Behavioral Science: Arctic Oscillation (2)

From a climate perspective, February 1985 was the last month when we observed global-average temperatures that were below the twentieth century average. When we arrive at February 2015 we will have had thirty years above average – an entire definition of “climate.” The warming has been especially large at the highest northern hemispheric latitudes. This means that there is a distinct trend in the North American averages temperature of the past twenty years. The warm parts at higher latitude are much warmer and the cool parts at middle latitudes are also warmer. If we stay on this trend, soon the average might not be below the 1961-1990 average.
