Earth's Relentless Warming Just Hit a Terrible New Threshold

May 18, 2016
In an age of broken temperature records, this one is especially worrisome.
The number of climate records broken in the last few years is stunning. But here's a new measure of misery: Not only did we just experience the hottest April in 137 years of record keeping, but it was the 12th consecutive month to set a new record.
It's been relentless. May 2015 was the hottest May in records dating back to 1880. That was followed by the hottest June. Then came a record July, August, September, October, November, December, January, February, March—and, we learned from the National Oceanic and Atmospheric Administration on Wednesday—the hottest April. In an age of rising temperatures, monthly heat records have become all too common. Still, a string of 12 of them is without precedent.
Perhaps even more remarkable is the magnitude of the new records. The extremes of recent months are such that we're only four months into 2016 and already there's a greater than 99 percent likelihood that this year will be the hottest on record, according to Gavin Schmidt, who directs NASA's Goddard Institute for Space Studies.
The chart below shows earth's warming climate, measured by land and sea, dating back to 1880.
