Before the yr has even come to a close , climate experts are certain that 2023 will be the hottest year in enter history . And while several factors are impacting this twelvemonth ’s record book passion , researchers sayhuman - caused climate changeis overwhelmingly responsible .
On Dec. 6 , the Copernicus Climate Change Service ( C3S ) — part of the European Union ’s space course of study — revealed that this year ’s boreal autumn , or September to November in the Northern Hemisphere , has been the warmest since their records began in 1940 , with temperatures reach 0.6 degree Fahrenheit ( 0.32 degree Celsius ) higher than ever before .
Rising global temperatures make natural disasters such as wildfires occur more often and become more destructive.
This year , we have already hadthe warmest summer on record , partly due to a criminal record - shattering heatwave that include a successiveness ofthree of the hottest - ever days globally . During 2023 , six case-by-case months also broke their spheric temperature phonograph recording , according to C3S , and Antarctica ’s sea icereached its humble horizontal surface since records began .
So far this year , average world temperatures have been 2.6 F ( 1.46 C ) higher than temperatures in preindustrial times and 0.2 F ( 0.13 C ) mellow than January to November in 2016 , which is the current hottest class on track record , according to C3S.
These " over-the-top " temperatures stand for that 2023 will be " the warmest year in recorded history , " C3S deputy directorSamantha Burgesssaid in astatement .
The summer and autumn of 2023 have been particularly warm.

The researchers note that the unusually warm circumboreal autumn was partly because of the latestEl Niñoevent — a phenomenon where lovesome water near the equator triggers warmer worldwide air temperatures — thatofficially get in June . El Niño willcontinue into next year , which mean that 2024 will probably be just as warm as 2023 .
For the last three years , spheric temperatures were kept in stop by atriple - dip La Niña event , which has the polar effects to El Niño . But without La Niña , sea open temperatures haveclimbed higher than ever before .
Global warming caused by rising greenhouse gas emissions is largely responsible for this year’s record temperatures.
Some other experts have suggested that the January 2022 irruption of Tonga ’s underwater volcano , whichpumped disc levels of H2O vaporisation into the atmosphere , may be partially responsible for for this year ’s record book heat by trapping more warmth in the atmosphere . However , these claimshave been largely debunked by researchers .
Despite these divisor , the major cause of go up temperature isglobal warmingcaused by runawaygreenhouse gasemissions , which have pin down more than25 billion atomic dud ' worth of vigor in our atmosphereover the last 50 years , the researcher write . This supernumerary energy has not only make zephyr temperatures to rocket but also makes utmost events such as El Niño much more unpredictable and potentially damaging , they read .
And the problem is getting bad . On Dec. 4 , scientists at the United Nations Climate Change Conference of the Parties ( COP28 ) harbinger thatglobal carbon discharge reached a new high school this yr .
" As long as greenhouse gas concentrations keep rising we ca n’t require dissimilar outcomes from those seen this class , " C3S directorCarlo Buontemposaid in the argument .
Theeffects of world warmingare becoming more obvious . In 2023 , research break that clime change iscausing major U.S. cities to sinkandmore than half of the public ’s turgid lake and reservoirs to shrink . Studies also predict that the Gulf Stream , which plays a lively character in sea circulation , could break down by as early as 2025 , and that rise up sea levels couldswamp the U.S. coastline by 2050 .

However , scientists say that we still have time to prevent further disaster .
direct mood modification expertMichael Mann , managing director of the Center for Science , Sustainability and the Media at the University of Pennsylvania , recently wrote in an judgement piece of music for Live Science that " we can still hold back the worst effects of climate modification " if we stop emit nursery gases as presently as possible .
There is still meter to preserve what we have now , Mann wrote . " But the windowpane of chance is narrowing . "
