Last calendar month was the hot January on disk , climate scientists have announce — despite the onslaught of a cold clime pattern in the Pacific and parts of theU.S. experiencing record book - bust common cold .
ball-shaped control surface line temperature averaged 55.81 degrees Fahrenheit ( 13.23 degrees Celsius ) in January 2025 , up from 55.65 F ( 13.14 C ) in 2024 — the late hottest January on disk . That increase is n’t vast , but scientist expected temperatures to be cooler this year .
January saw deadly wildfires sweep through parts of Los Angeles as the planet got warmer.
Earthentered La Niñain January , which is the cold phase angle of a natural climate pattern called theEl Niño - Southern Oscillation cps . The El Niño phase press spherical temperatures up , which happened in 2023 and 2024 , while La Niña typically brings them down . However , the current La Niña arrive later than scientists ask and is unusually weak .
The remarkably high-pitched temperature in January 2025 continue an ominous trend of global thaw . Last year was thehottest year on recordand the first full yr to transgress 2.7 F ( 1.5 C ) of warming above pre - industrial levels — the judge average temperature between 1850 and 1900 . World leaders previously agreed to limit warming to rather below 2.7 fluorine and well below 3.6 F ( 2 blow ) in the 2015Paris Agreement , a lawfully binding international treaty .
In January this year , the warming was 3.15 F ( 1.75 vitamin C ) above pre - industrial grade . This mark the 18th month out of the last 19 to exceed 2.7 farad , harmonize to astatementreleased by the European Union ’s Copernicus Climate Change Service .
" January 2025 is another surprising month , continuing the platter temperature detect throughout the last two years , despite the ontogenesis of La Niña consideration in the tropical Pacific and their irregular cooling gist on globose temperatures,“Samantha Burgess , the strategical lead for climate at the European Centre for Medium - Range Weather Forecasts , which carry out the Copernicus computer programme , said in the statement .

U.S. colder than average
Weather form vary across the major planet , so a global increment in middling temperature does n’t necessarily mean that every region experiences thaw . Overall , the U.S. was cold than average in January , withthundersnowstriking the East Coast and Midwest andhistoric snow stormscoating the Deep South and Gulf Coast . However , dry conditions in Southern Californiacontributed to the pestilent wildfire that devastated Los Angeles , while places like Minnesota sawrecord - give away warmth .
Warmer - than - mediocre temperature were also reported north of the neighboring U.S. Alaskawas 5 F ( 2.8 C)above norm , The Washington Postreported . Northeastern and northwesterly Canada were also relatively warm , fit in to the Copernicus program ’s statement .

Across the earth , Australia baked inhistoric heatwaves , while southerly South America , Africa , Antarctica , Siberia and parts of Europe all get mostly above - average temperature .
Global warming is primarily attributed to world liberate record amounts ofgreenhouse gasesinto the standard atmosphere by combust fossil fuel , accord to astatementreleased by the United Nations . Carbon dioxide ( CO₂ ) , methane ( CH₄ ) and other glasshouse flatulence snare heating system in the atmosphere , warm up the major planet .
Climate modification threatensbillions of citizenry . Theeffects of spheric warminginclude fueling extreme atmospheric condition such as wildfires;raising ocean levelsthat menace coastal communities ; and drying agrarian lands , which in turn compromises human beings ’s power to uprise food . Unchecked climate change will also send manyspecies to extermination .
