On the 10th, the European Union's climate monitoring agency, Copernicus Climate Change Service, released a press release stating that 2024 has become the hottest year since records began in 1850, with multiple key climate indicators breaking records.
Copernicus Climate Change Service climate scientist Julian Nicholas recently told Xinhua News Agency reporters that due to natural climate variability, global temperatures will slightly decrease in the short term, and the global average temperature in 2025 is not expected to be higher than that of 2023 and 2024.
The World Meteorological Organization recently released forecasts indicating that there is more than a 50% chance of a La Niña phenomenon occurring from December 2024 to February 2025. Nicholas explained that in 2023 and 2024, a strong El Niño phenomenon caused above-average sea surface temperatures in the equatorial Pacific, which drove global temperatures up. However, the El Niño phenomenon is temporary, lasting for a few months before shifting to a La Niña phenomenon. This phenomenon leads to below-average sea surface temperatures in the equatorial Pacific, which has a limiting effect on global temperatures.
Global Average Temperatures Still on the Rise
He also emphasized that although the global average temperature in 2025 is unlikely to exceed the levels of the previous two years, in the long term, global average temperatures still show an upward trend, with carbon dioxide emissions remaining at record levels.
Nicholas said that even a slight increase in temperature, such as by a few tenths of a degree Celsius, can trigger more severe and widespread environmental chain reactions. Therefore, 'we must do everything possible to reduce global greenhouse gas emissions as quickly as possible.'
