Federal officials say July was Earth’s hottest month on record, smashing old marks.
July’s average temperature was 61.86 degrees Fahrenheit, beating the previous global mark set in 1998 and 2010 by about one-seventh of a degree. That’s a large margin for weather records.
Records go back to 1880, but nine of the 10 hottest months on record have happened since 2005. The first seven months of 2015 are the hottest January-to-July span on record.
The new records are “reaffirming what we already know,” Jake Crouch, National Oceanic and Atmospheric Administration climate scientist, said during a press call.
“The world is warming, it’s continuing to warm.”
Earth’s warming is getting a boost this year from an El Nino warming of the Pacific Ocean, Crouch added.
NOAA scientists think it’s quite likely that 2015 will end up the hottest year on record, beating last year.
“I think, from my perspective, I would say [I’m] 99% certain that it’s going to be the warmest year on record,” NOAA climate scientist Jessica Blunden said during the press call.
“For it to change you’re going to have to have a big change in the ocean temperature, which we’ve seen only trending warmer over time.”
Earlier this week, preliminary data from NASA — along with information from the Japan Meteorological Administration — suggested that July was the warmest month on record. Now we know for sure.
The hottest July milestone comes as the U.S. government mobilizes military units to help respond to an escalating outbreak of wildfires throughout the West, much of which is tinderbox-dry and scorchingly hot.
