Tuesday set an unofficial record for the hottest day on Earth. Wednesday may break it.

The planet’s temperature spiked on Tuesday to its hottest day in decades and likely centuries, and Wednesday could become the third straight day Earth unofficially marks a record-breaking high.
It’s the latest in a series of climate-change extremes that alarm but don’t surprise scientists.


The globe’s average temperature reached 62.9 degrees Fahrenheit (17.18 degrees Celsius) on Tuesday, according to the University of Maine’s Climate Reanalyzer, a common tool based on satellite data, observations, and computer simulations and used by climate scientists for a glimpse of the world’s condition. On Monday, the average temperature was 62.6 degrees Fahrenheit (17.01 degrees Celsius), setting a record that lasted only 24 hours.

For scientists, it’s a sweaty case of I-told-you-so.

“A record like this is another piece of evidence for the now massively supported proposition that global warming is pushing us into a hotter future,” said Stanford University climate scientist Chris Field, who was not part of the calculations.

On Wednesday, 38 million Americans were under some kind of heat alert, said National Oceanic and Atmospheric Administration chief scientist Sarah Kapnick. She said the global heat is from a natural El Nino warming of the Pacific that heats up the planet as it changes worldwide weather on top of human-caused climate change from the burning of coal, oil and gas.

Fever chart: Earth had its hottest decade on record in 2010s

Published 4:09 PM CDT, January 15, 2020

WASHINGTON (AP) — The decade that just ended was by far the hottest ever measured on Earth, capped off by the second-warmest year on record, two U.S. agencies reported Wednesday. And scientists said they see no end to the way man-made climate change keeps shattering records.

“If you think you’ve heard this story before, you haven’t seen anything yet,” Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies, said at the close of a decade plagued by raging wildfires, melting ice and extreme weather that researchers have repeatedly tied to human activity.

Schmidt said Earth as a whole is probably the hottest it has been during the Holocene — the past 11,500 years or so — meaning this could be the warmest period since the dawn of civilization. But scientists’ estimates of ancient global temperatures, based on tree rings, ice cores and other telltale signs, are not precise enough to say that with certainty.
