January 2025 was the hottest January on record, despite the fact that it was thought to be unlikely.

WASHINGTON – The world has grown stronger in January to yet another monthly fever record despite the unusually chilly US. Cooling Ranina The forecast for 2025 is slightly less, according to European Climate Services Copernicus.

The surprising January heat record is Climate science Others who claim global warming is on the rise, including heavyweight and former NASA scientist James Hansen. This is an argument that divides the research community.

January 2025, Copernicus calculated that it was 0.09 degrees Celsius (0.16 degrees Fahrenheit) warmer than the previous January 2024, and 1.75 C (3.15 F) warmer than before the industrial era. . The 18th month of the last 19th month was an international agreement that the world agreed to over the pre-industrial era to warm restrictions of 1.5° Celsius (2.7° Fahrenheit). Scientists will not consider restrictions to be violated unless the global temperatures stay for more than 20 years.

The Copernicus record appears in 1940, but other US and British records date back to 1850, with scientists using proxies such as tree rings saying this era is the warmest of around 120,000 years. Masu.

The biggest driver in record heat is greenhouse gas Accumulation from burning of coal, oil and natural gashowever, the natural contribution to temperature changes is not acting as expected, said Samantha Burgess, the European Meteorological Agency’s strategic climate leader.

A large natural factor of earth temperature is usually the natural cycle of changes in the equatorial Pacific oceans. When the Central Pacific Ocean is particularly warm, it is El Nino, and the temperature on the earth tends to skyrocket. Last year, it was quite El Niño, but it ended in June last year, and the year is warmer than originally expected. Hottest on record.

El Niño’s cooler flip side, Lanina, tends to weaken the effects of global warming, with record temperatures much lower. Lanina started in January after brewing for several months. Last month, climate scientists predicted that 2025 would not be as hot as 2024 or 2023. Lanina is a big reason.

“The Equatorial Pacific Ocean is not creating a warming condition due to our global climate, but we are still seeing record temperatures,” Burgess said.

Usually, temperatures drop rapidly after El Nino like last year, but “we haven’t seen that,” Burgess told The Associated Press.

For Americans, record-breaking warm January news may seem strange considering how cold it was. But the United States is only a small part of the planet’s surface, and “a much larger area on the planet’s surface is much warmer than average,” Burgess said.

January was an unseasonably calm in the Arctic. In parts of Canada’s Arctic, Faneheit, 54 degrees above average, was warmer with warmer temperatures, and sea ice began to melt in the area, Burgess said.

Copernicus said the Arctic Circle tied the January record this month Lowest sea ice. The US-based national snow and ice data center was considered to be the second lowest in 2018.

Burgess said that February has already started more coolers than last year.

But Hansen, a former NASA scientist known as the Godfather of Climate Science, should not count 2025 in the hottest year race. He is currently at Columbia University.

In Journal Environment: Research into Science and Policy for Sustainable Development, Hansen and colleagues said the past 15 years have been warmed by about twice the rate of the past 40 years.

“I’m sure this high rate will last for at least several years,” Hansen told The Associated Press in an interview. “It will be a nip and tack between 2024 and 2025 over the whole year.”

Since 2020, even taking out El Nino variations and expected climate change, there have been significant temperature rises, Hansen said. He notes the recent shipping regulations that have led to a reduction in sulfur pollution, which reflect some sunlight away from the Earth and effectively reduces warming. And that will continue, he said.

“The record-breaking warmth through 2023 and 2024 is harsh to say the least,” said Jonathan Oberpeck, dean of the University of Michigan Department of Environment. “There appears to be no doubt that the impacts of global warming and climate change are accelerating.”

However, Gabe Vecchi of Princeton and Michael Mann of the University of Pennsylvania said he disagreed with Hansen about the acceleration. Vecchi said there was not enough data to show that this is not a random opportunity. Mann said the rise in temperature is within what the climate model predicts.
