If you’ve been wondering why your coats stayed in the closet and your heater remained off for the first part of fall, wonder no more. This October was the warmest on record. Ever.
Last month beat out all the other Octobers to get the title of hottest Octobersince record-keeping began in the late 1800’s. It was also the highest deviation from ‘normal’ global temperatures. Those temperatures were recorded between 1951 and 1980, and are averaged to get a general baseline. The data comes from NASA’s Goddard Institute for Space Studies, which looks at temperature changes over long periods of time (decades as opposed to days).
If it sounds like a familiar story, that’s because it is. Last winter was one of the warmest on record, even with all the snow. 2014 and 2012 were also record-breaking years, and with the addition of October to its already hot lineup, 2015 is likely to surpass both.
Extreme heat is now 4 times more likely than it was before the industrial revolution, and that shows no signs of stopping.
