The US is freezing and La Nina usually eases warming. Earth just set another heat record anyway

WASHINGTON (AP) – The world was heated to another monthly thermal record in January, despite the abnormally cold United States, La Nina cooling and expectations for 2025 are slightly lower, according to Europe. Copernicus Climate Service.

The sudden heat record coincides with January with a new study conducted by a heavy group in climate science, former NASA world James Hansen, and others argue that Global warming Rolling. It is a claim that divides the research community.

January 2025 in the world was 0.09 ° C (0.16 degrees Fahrenheit) warmer than January 2024, the most important of January, and was 1.75 ° C (3.15 Fahrenheit) warmer than before industrial times, calculated Copernicus. It was the eighteenth month of the last 19 -year -old who struck or passed the world at the international level Warming limit 1.5 degrees Celsius (2.7 A) Above the pre -industrial times. Scientists will not consider this limit that is breached Unless global temperatures remain over 20 years old.

The history of Copenicus date until 1940, but other American and British records date back to 1850, and scientists who use agents like tree rings say that this age is the warmer in about 120,000 years or since the beginning of human civilization.

Samantha Burgis, strategic climate bullets in the European weather said that the largest driver for registration is the accumulation of greenhouse gases from burning coal, oil and natural gas, but the natural contributions to changing the temperature were not behaving as expected. an agency.

The large natural factor in global temperatures is usually the natural cycle of changes in the waters of the Pacific Pacific. When the Pacific Central is particularly warm, it tends global temperatures to rise. Last year, Nino was great, though It ended last June The year was warmer than it was expected at the beginning, which is the most record.

The EL Nino’s Cooler Flip, La Nina, tends to alleviate the effects of global warming, making standard temperatures less likely. No Nina It started in January After fermentation for several months. Only last month, climate scientists were Prediction that 2025 It will not be hot like 2024 or 2023, with La Nina is a major cause.

“Although the Pacific Ocean does not create heating conditions for our global climate, we still see record temperatures,” said Borges.

Usually after Nino, like last year, temperatures decrease quickly, but “we haven’t seen it”, Borgis told Associated Press.

For Americans, news of a warm record in January may seem strange due to the coldness of it. But the United States is just a small part of the planet’s surface, and “more space than the surface of the planet was much warmer than average.”

January was unreasonable in the Arctic. Burgis said that parts of the Canadian North Pole had temperatures of 30 ° C (54 Fahrenheit) warmer than the average, and the temperatures in the warm sea ice began to melt in places.

Copernicus said the Arctic this month linked the January record to the lowest sea ice. The US ice and ice data center in the United States had obtained it The second is lessBehind 2018.

Borges said that February has already started colder than last year.

Do not calculate 2025 in the race for a year of hotness, Hansen saidThe former world of NASA, which was called the godfather of climate science. He is now at Columbia University. In a study in the magazine Environment: Science and Politics for Sustainable DevelopmentHansen and his colleagues said that the past fifteen years have declined about twice the average rate of the previous forty years.

“I am sure that this higher rate will continue for at least several years,” Hansen told Associated Press in an interview. “Over the course of the full year, it will be between 2024 and 2025.”

Hansen said that there was an increase in a noticeable temperature, even when the EL Nino differences were removed and the expected climate changed since 2020. He pointed out that the recent shipping regulations that led to a decrease in sulfur pollution, which reflects some sunlight away from Earth and effectively reduces warming. He said that would continue.

“The continuation of the standard warmth until 2023, 2024, and now until the first month of 2025 is something that is not said,” said the dean of the Environment at the University of Michigan, who was not part of Hansen’s study. “Global warming and the effects of climate change do not seem to be accelerated.”

But Gabi Vicky from Princeton and the University of Pennsylvania Michael Man said they did not agree with Hansen on acceleration. Vecchi said that there is not enough data to show that this is not a random opportunity. Man said that increased temperature is still among the climate models.
