This year, the temperature on Earth has gone through the roof, and scientists have confirmed what most of the planet has already experienced: 2023 will officially be the hottest year on record.

CNN writes about it.

An analysis by the European Union's Copernicus Climate Change Service found that global temperatures this year will be more than 1.4 degrees Celsius above pre-industrial levels — close to the 1.5-degree threshold set by the Paris climate agreement and beyond which scientists say people and ecosystems will struggle to adapt.

What warming means for the planet

Every month since June has been the hottest month on record, and November was no exception. The moon was about 1.75 degrees warmer than pre-industrial levels, and for two days the temperature exceeded 2 degrees, raising scientists worried about what this means for the planet in the coming years.

The report comes as delegates from more than 150 countries gathered in Dubai for COP28, the UN's annual climate summit, which has sparked a heated debate about the need to phase out fossil fuels that are warming the planet.

"The timing couldn't be more urgent," Brenda Ekwurtzel, director of climate science at the Union of Concerned Scientists, who was not involved in the preparation of the report, said in an interview with CNN.

"The rich, high-emitting countries that have contributed the most to this record year," she added, "have a greater responsibility to move away from fossil fuels in a fair, rapid and financed manner to help limit the impacts of extreme weather and climate change."

What Caused Exceptional Warming This Year

Scientists say the exceptional heat of 2023 is the result of the combined impact of El Niño and human-caused climate change. A series of deadly heatwaves and extreme record-breaking temperatures have hit several continents this year, while unprecedented ocean heat has covered much of the globe.

According to Copernicus, autumn in the Northern Hemisphere this year was the warmest on record around the world "by a wide margin". November was also wetter than average across much of Europe, and Storm Ciaran brought heavy rain and flooding to many regions, including Italy.

With temperatures rising next year, the world appears to be on track to tackle 1.5 degrees of warming in the long term in the coming years. While global warming is a concern that temperatures exceed this figure for several months, scientists are particularly concerned that the planet will remain above 1.5 degrees in the long term.

A separate report released on Tuesday, December 5, by the World Meteorological Organization said that the decade between 2011 and 2020 was the hottest on record on the planet's land and oceans, as the rate of climate change "increased alarmingly" and "accelerated" the dramatic loss of glaciers and sea level rise during that period.

"As long as greenhouse gas concentrations continue to rise, we cannot expect different results than what we have seen this year," said Copernicus director Carlo Buontempo. "Temperatures will continue to rise, as will the effects of heat and drought."

Recall that life on Earth is under threat. Climatologists predict that between three and six billion people could be "outside the habitable region" by the end of the century.
