Brussels/London — The world just experienced its warmest January on record, marking the first 12-month period in which temperatures averaged more than 1.5°C (2.7F) above pre-industrial times, the EU’s climate change monitoring service said on Thursday.
Already 2023 was the planet’s hottest year in global records going back to 1850, as human-caused climate change and El Nino, the weather pattern that warms the surface waters in the eastern Pacific Ocean, pushed temperatures higher.
“It is a significant milestone to see the global mean temperature for a 12-month period exceed 1.5°C above pre-industrial temperatures for the first time,” Matt Patterson, an atmospheric physicist at the University of Oxford, said.
The previous warmest January was in 2020, according to the Copernicus Climate Change Service (C3S) records, which go back to 1950.
Countries agreed at UN climate talks in Paris in 2015 to keep global warming well below 2°C and aim to limit it to 1.5°C, a level regarded as crucial to preventing the most severe consequences.
The first 12-month period of exceeding 1.5°C does not yet mean the Paris goal has been missed, as the UN agreement refers to an average global temperature over decades.
Some scientists, however, have said the 1.5°C aim can no longer realistically be met, and have urged governments to act faster to cut CO2 emissions to limit the amount of overshoot of the target.
“Rapid reductions in greenhouse gas emissions are the only way to stop global temperatures increasing,” C3S deputy director Samantha Burgess said.
At the same time, economic weakness and political pressures are challenging government will to implement policies to curb greenhouse gases as politicians strive for re-election in a bumper year for democratic elections.
2024?
Every month since June 2023 has been the world's hottest on record, compared with the corresponding month in previous years.
US scientists have said 2024 has a one-in-three chance of being even hotter than last year, and a 99% chance of ranking in the top five warmest years.
El Nino began to weaken last month, and scientists have indicated it could shift to the cooler La Nina counterpart later this year. Still, average global sea surface temperatures last month were the highest for any January on record.
While it is winter in the northern hemisphere, in parts of South America, experiencing the southern hemisphere summer, temperatures are again blistering.
Argentina endured a heatwave between January 21 and 31, while the Chilean capital of Santiago registered its third hottest temperature on record on January 31, climbing above 37C.
Such heat in central Chile caused deadly wildfires that killed at least 131 people in early February.
