The planet’s temperature spiked on Tuesday to its hottest day in at least 44 years and likely much longer, and Wednesday could become the third straight day Earth unofficially marks a record-breaking high, 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 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), breaking a record that lasted only 24 hours.
While it is not an official National Oceanic and Atmospheric Administration record, “this is showing us an indication of where we are right now,” NOAA chief scientist Sarah Kapnick said. Even though the dataset used for the unofficial record goes back only to 1979, she said that given other data, it’s likely the hottest day in “several hundred years that we’ve experienced”.
The previous hottest day was in August 2021, Kapnick said. “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. With many places seeing temperatures near 100 degrees Fahrenheit (37.8 degrees Celsius), the new average temperatures might not seem very hot. But Tuesday’s global high was nearly 1.8 degrees Fahrenheit (a full degree Celsius) higher than the 1979-2000 average, which already tops the 20th- and 19th-century averages. Higher temperatures translate into brutal conditions for people all over the world. When the heat spikes, humans suffer health effects – especially young and elderly people, who are vulnerable to heat even under normal conditions. The highs come after months of “truly unreal meteorology and climate stats for the year,” such as off-the-chart record warmth in the North Atlantic, record low sea ice in Antarctica and a rapidly strengthening El Nino, said University of Oklahoma meteorology professor Jason Furtado.
Scientists generally use much longer measurements – months, years, decades – to track the Earth’s warming. But the new figures are an indication that climate change is reaching uncharted territory. Wednesday may bring another unofficial record, with the Climate Reanalyzer again forecasting record or near-record heat. Antarctica’s average forecast for Wednesday is a whopping 4.5 degrees C warmer than the 1979-2000 average.
