NASA yesterday updated its yearly analysis of global surface temperatures, adding measurements from 2012 and reaffirming that the planet is in the midst of a prolonged warming trend. But as Peter Aldhous at New Scientist points out, the rising average temperature for the entire planet is only so illustrative of what’s happening. Much more of the story is contained in local temperature changes, which in some cases are much more dramatic than the global average.
Aldhous and colleagues used data from the NASA analysis reflecting the entire historical temperature record since 1880 to create an informative and smartly interactive map of the world. The visualization uses colors to compare the average surface temperatures for various time frames over the past 120 years to the average temperature during the period from 1951 to 1980, the span the NASA analysis refers to as a baseline. The data combines numbers from thousands of land-based measuring stations with readings from ships and satellites.
