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. On Wednesday, 38 million Americans were under some kind of heat alert, said National Oceanic and Atmospheric Administration chief scientist Sarah Kapnick.
“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 Monday, the average temperature was 62.6 degrees Fahrenheit (17.01 degrees Celsius), setting a record that lasted only 24 hours.įor scientists, it’s a sweaty case of I-told-you-so. 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. It’s the latest in a series of climate-change extremes that alarm but don’t surprise scientists.
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. By MELINA WALLING and SETH BORENSTEIN (Associated Press)
