New study finds Earth warming at record rate, but no evidence of climate change accelerating

The rate Earth is warming hit an all-time high in 2023 with 92% of last year’s surprising record-shattering heat caused by humans, top scientists calculated.

The group of 57 scientists from around the world used United Nations-approved methods to examine what’s behind last year’s deadly burst of heat. They said even with a faster warming rate they don’t see evidence of significant acceleration in human-caused climate change beyond increased fossil fuel burning.

Last year’s record temperatures were so unusual that scientists have been debating what’s behind the big jump and whether climate change is accelerating or if other factors are in play.

“If you look at this world accelerating or going through a big tipping point, things aren’t doing that,” study lead author Piers Forster, a Leeds University climate scientist, said. “Things are increasing in temperature and getting worse in sort of exactly the way we predicted.”

It’s pretty much explained by the buildup of carbon dioxide from rising fossil fuel use, he and a co-author said.

Last year the rate of warming hit 0.26 degrees Celsius (0.47 degrees Fahrenheit) per decade — up from 0.25 degrees Celsius (0.45 degrees Fahrenheit) the year before. That’s not a significant difference, though it does make this year’s rate the highest ever, Forster said.

Still, outside scientists said this report highlights an ever more alarming situation.

“Choosing to act on climate has become a political talking point but this report should be a reminder to people that in fact it is fundamentally a choice to save human lives,” said University of Wisconsin climate scientist Andrea Dutton, who wasn’t part of the international study team. “To me, that is something worth fighting for.”
