Tuesday Set an Unofficial Record For the Hottest Day On Earth (apnews.com) 11

An anonymous reader quotes a report from the Associated Press: 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.
University of Maine climate scientist Sean Birkle, creator of the Climate Reanalyzer, said the daily figures are unofficial but a useful snapshot of what's happening in a warming world. Think of it as the temperature of someone who's ill, he said: It tells you something might be wrong, but you need longer-term records to work like a doctor's exam for a complete picture. While the figures are not an official government record, "this is showing us an indication of where we are right now," said National Oceanic and Atmospheric Administration chief scientist Sarah Kapnick. And NOAA indicated it will take the figures into consideration for its official record calculations.
Even though the dataset used for the unofficial record goes back only to 1979, Kapnick said that given other data, the world is likely seeing the hottest day in "several hundred years that we've experienced." Scientists generally use much longer measurements -- months, years, decades -- to track the Earth's warming. But the daily highs are an indication that climate change is reaching uncharted territory.
