Both the Goddard Institute for Space Studies (GISS) and the National Oceanic and Atmospheric Administration (NOAA) have released their global October surface temperature anomaly data.
October 2013 land/ocean combined temperature anomaly data from GISS. Reds show above-normal temperatures, while blues indicate below-normal temperatures.
According to GISS, October 2013 ended up as tied for 8th warmest on record (records go back to 1880) with a global temperature anomaly of +0.61 C. or +1.10 F. Temperatures are measured against the (1951-1980) base period for GISS.
According to the NOAA database, October 2013 was the 7th warmest October going back to 1880 with a land/ocean combined temperature anomaly of +0.63 C. or +1.13 F. NOAA temperatures are measured against the 20th century average.
A look at the increase in global ocean heat content.
Recent strong, summer warming over most of Europe during the past several decades was likely the warmest such period of the last two millennia, according to new research.
New research claims that the string of record high global temperatures were extremely unlikely to have occurred in the absence of human-caused climate change.
2015 was a record breaking year for temperature and then some......
Are satellite measured temperatures of the earth's troposphere reliable?
Cloud cover over the Greenland Ice Sheet is playing a larger role than previously thought by raising the temperature of the ice sheet some 2 to 3 degrees compared to days with no clouds.
