Sick of hearing about record heat? Scientists say those numbers paint the story of a warming world:
The summer of 2023 is behaving like a broken record about broken records.
Nearly every major climate-tracking organization proclaimed June the hottest June ever. Then July 4 became the globe's hottest day, albeit unofficially, according to the University of Maine's Climate Reanalyzer. It was quickly overtaken by July 5 and July 6. Next came the hottest week, a tad more official, stamped into the books by the World Meteorological Organization and the Japanese Meteorological Agency.
With a summer of extreme weather records dominating the news, meteorologists and scientists say records like these give a glimpse of the big picture: a warming planet caused by climate change. It's a picture that comes in the vibrant reds and purples representing heat on daily weather maps online, in newspapers and on television.
Beyond the maps and the numbers are real harms that kill. More than 100 people have died in heat waves in the United States and India so far this summer.
[...] In the past 30 days, nearly 5,000 heat and rainfall records have been broken or tied in the U.S. and more than 10,000 records set globally, according to NOAA [the National Oceanic and Atmospheric Administration]. Texas cities and towns alone have set 369 daily high temperature records since June 1.
Since 2000, the U.S. has set about twice as many records for heat as those for cold.
"Records go back to the late 19th century and we can see that there has been a decade-on-decade increase in temperatures," said Gavin Schmidt, director of NASA's Goddard Institute for Space Studies, keeper of the agency's climate records. "What's happening now is certainly increasing the chances that 2023 will be the warmest year on record. My calculations suggest that there's, right now, a 50-50 chance."
