Record May heat, from Alaska to India and especially in the oceans, put the global average temperature at 15.65°C, according to National Oceanic and Atmospheric Administration (NOAA).
There's still a good chance that June will break records even as El Niño, one of two main reasons for record heat, dissipates, scientists say, Daily Mail reported.
And in the US Southwest temperatures are forecast to dance near 120 degrees later this week into next week. NOAA's July through September forecast is for hotter-than-average temperatures in the entire United States except a tiny circle of southeastern Texas.
“We're in a new neighborhood now as far as global temperature,” said Deke Arndt, NOAA's climate monitoring chief. “We've kind of left the previous decade behind.”
But it's not quite as broiling as it has been. May only broke the record — set in 2015 — by .04 degrees.
It's the first time since November that a month wasn't a full degree Celsius hotter than the 20th-century average.
“It is slightly off from the kind of unprecedented large global temperatures we've seen in the last five to seven months,” Arndt says.
An animation created by climate scientist Ed Hawkins has revealed how global temperatures have increased by year on year since 1850.
Arndt, like nearly every major climate scientist, says the record warm temperatures are due to a strong El Niño placed on top of man-made global warming from heat-trapping gases that come from the burning of fossil fuels.
The El Niño has just dissipated and forecasters expect its cooler flip side, La Niña, to kick in soon, which should keep global temperatures a bit lower than they've been, but still warmer than 20th-century average, Arndt said.
But that may not be quite enough to keep 2016 from being the third straight record hot year, Arndt says.
That's because so far, 2016 is averaging 13.06°C , which beats the previous January to May record set last year by 0.43 degrees.
Jonathan Overpeck, a climate scientist at the University of Arizona, just came back from India and its record-breaking heat wave in time for potential record breaking heat in parts of Arizona.
“Thirteen months of consecutive record breaking heat is really unprecedented, and it's yet another visceral glimpse of what is yet to come as the planet warms up even a lot more,' Overpeck said in an email.
