A new study of up-to-date global surface temperature data concludes that temperatures in the past decade have continued to rise at a pace as fast as was witnessed in the previous two decades. The results published in Reviews of Geophysics by NASA scientist Jim Hansen, et al were corrected for urban heat island and other corrections to the instrumental record. In the paper, the authors draw attention to many striking observations, including the fact that a record high of the 12-month running mean of global average temperatures was reached in 2010. Data used in this analysis spans 1880-2010 and draws on 6300 land-based measurement stations as well as a mixture of satellite and ship and buoy measurements to gauge sea surface temperatures. A summary and full text version of the paper are available through the links below.
