Continuing the hottest-month-ever trend... NOAA has released their global temperature data for June 2010 confirming that the month was the warmest on record, judged by combined global and ocean surface temperature. The January-June and April-June 2010 periods were also the hottest observed, since records began in the late nineteenth century. Just using average land surface temperatures, June and the April-June period were also hottest, while January-June ranks second hottest, behind 2007.
During June, the combined global and ocean surface temperature was 16.2°C, 0.6°C above the 20th century average. Land temps rose above the 20th century average of 55.9°C by 1.07°C.
NOAA notes, during June warmer than average temperatures dominated the globe, with "prominent warmth" in Peru, central and eastern United States, eastern and western Asia.
As for the year-to-date figures, the global combined land and ocean surface temperature has been 0.68°C above the 20th century average of 14.2°C for the first six months of the year. April-June was 0.7°C above average.
Poignantly illustrating the concept that just because the overall trend continues steadily upward not every place is affected similarly, NOAA points out that cooler than average temperatures were felt in Scandinavia, southern China, and the northwest US. Furthermore, in Spain nationwide temperatures were 0.4°C above the long-term average, the coolest June since 1997.
