January 2025. It was the hottest January, despite the factors thought to be less likely

Washington – The world was warmed to another monthly thermal record in January, despite the abnormally cold United States, cooling la nina and predictions of slightly less hot 2025, according to the European Copernicus Climate Service.

The surprising January thermal record matches the new study a Climate science Heavy category, former top -notch -high scientist James Hansen and others claim that global warming is accelerated. It is a claim that shares the research community.

January 2025. Globally was 0.09 degrees Celsius (0.16 degrees Fahrenheit) warmer than January 2024, previously the hottest January, and was 1.75 C (3.15 F) warmer than it was before the industrial weather, The Coperniks calculated. It was the 18th month of the last 19 years that the world had hit or adopted an internationally agreed heating limit of 1.5 Celsius (2,7 Fahrenheit) above the pre -industrial times. Scientists will not consider the border as violated, unless global temperatures remain above it for 20 years.

Copernicus records dates from 1940, but other American and British records date back to 1850, and scientists who use proxy, like trees rings, say that this time is the warmest in about 120,000 years – or from the beginning of human civilization.

By far the biggest driver of a record heat is greenhouse gas accumulation from coal burning, oil and natural gasBut the natural contributions to temperature changes did not seem just as expected, said Samantha Burgess, a strategic leadership for the European Time Agency Climate.

A large natural factor of global temperatures is usually a natural cycle of changes in the equatorial waters of the Pacific. When the central Pacific is especially warm, it is El Nino, and global temperatures tend to. Last year was a significant El Nino, although it ended last June, and the year was even warmer than it was initially expected, The warmest on the record.

The El Nino cooler side, and La Nina, seeks to dampen the effects of global warming, making record temperatures far less likely. And La Nina began in January after she had been cooking for months. Only last month, climate scientists predicted that 2025 would not be hot as 2024 or 2023, and La Nina is the main reason.

“Although the Equatorial Pacific Ocean does not create conditions that heat up for our global climate, we still see record temperatures,” Burgess said, adding that there is much because of a record heat in the rest of the world ocean.

Usually after El Nino, like last year, temperatures fall quickly, but “we didn’t see that,” Burgess told Associated Press.

For Americans, news of a record warm January can seem unusual considering how cold it is. But now they are just a small part of the planet surface, and “there were much larger area of ​​the planet’s surface, much, much warmer than average,” Burgess said.

January was unusually mild in the Arctic. Parts of the Canadian Arctic had temperatures 54 degrees Fahneheit warmer than average, and temperatures were so warm sea ice to melt in places, Burgess said.

Copernicus said the Arctic had tied the record this month in January for Lowest sea ice. American National Snow and Snow and Ice Data had it as the second lowest, after 2018.

February has already started colder than last year, Burgess said.

But don’t count in 2025 in the race for the warmest year, said Hansen, former NASA scientist who was called the godfather of climate science. He is now at Columbia University.

In a study in Environment: Science and Policy for Sustainable Development, Hansen and colleagues have said that for the last 15 years they have been warmed up about twice the previous 40 years.

“I am convinced that this larger rate will continue for at least a few years,” Hansen said in an interview with Associated Press. “Throughout the year, it will be striking between 2024 and 2025.”

There was a noticeable increase in temperature even when eliminating the variations of El Nino -ai expected climate change since 2020, Hansen said. He noted that the recent shipping regulations that resulted in reduced pollution of sulfur, which reflects some sunlight from the ground and effectively reduces warming. And that will continue, he said.

“Persistence of record heat until 2023, 2024, and now in the first month of 2025, he will least say,” said Dean Overpeck, the environment of the University of Michigan, who was not part of Hansen’s study. “It seems that a little doubt that global warming and climate change influences are accelerating.”

But Princeton’s Gabe Vecchi and the University of Pennsylvania Michael Mann said they did not agree with Hansen about acceleration. Vecchi said there was not enough information that would show that it was not a random chance. Mann said that the temperature increase are still within what climate models are forecast.
