NASA And JMA: Global October 2014 Warmest On Record; 3rd Straight Record Warmest Month

For the third month in a row, global temperatures reached record territory according to newly available data from NASA. And if one global temperature record isn’t enough, the Japanese Meteorological Agency also provided new data on Friday that showed the warmest October on record.

Data from NASA Goddard Institute for Space Studies (GISS) show this October was 1.4°F above the 1951-1980 average they use as their baseline. That didn’t set a monthly mark, as did August and September, but rather tied 2005 as the warmest October since 1880. That keeps 2014 on track to be the hottest year on record.

While individual hot years or months don’t necessarily stand out, it’s notable that all 10 of the warmest years on record have all come since 1998, one of the clearest signs that the climate is warming due in large part to greenhouse gas emissions.

NASA data reveal that far eastern Siberia was an eye-popping 10°F above normal for October, but western Europe, northern Africa and western North America also saw temperatures up to 7°F hotter than average. The data also comes a day after the National Climatic Data Center (NCDC) released its October numbers for the U.S. that showed the lower 48 had its fourth-warmest October on record.
