Global surface temperatures have remained at or near record-warm levels throughout 2015, leading many to prognosticate that 2015 will eclipse 2014 as the warmest year on record1-3, perhaps by a relatively large margin.
Based on the latest data from NOAA’s global surface temperature dataset (NOAAGlobalTemp), the 2015 global temperature average through July is running 0.09°C (0.16°F) above the 2014 average and 0.13°C above the January-July 2014 average. That might not seem like a lot, but 2014 eclipsed 2010 as the warmest year on record by an even smaller margin, 0.04°C.
