Hottest Year Ever: The year 2023 was the hottest ever, with global temperatures coming close to the 1.5-degree Celsius limit. The previous warmest year was 2016, but 2023 overtook 2016 as the hottest year ever after June 2023 saw unprecedented global temperatures, according to the European Union’s Copernicus Climate Change Service.
In 2023, daily global temperature averages had briefly surpassed pre-industrial levels by more than two degrees Celsius. Greenhouse gas concentrations, the El Niño phenomenon, and other natural variants are the major drivers behind the climate extremes observed in 2023.
El Niño began in July 2023, according to the World Meteorological Organization (WMO).
The Intergovernmental Panel on Climate Change (IPCC) considers 1850-1900 the pre-industrial period.
Temperature records in 2023
According to the European Union, the global average temperature in 2023 was 14.98 degrees Celsius. This was 0.17 degrees Celsius higher than the previous highest value in 2016, which was 14.81 degrees Celsius.
The year 2023 was 0.6 degrees Celsius wArmer than the 1991-2020 average, and 1.48 degrees Celsius warmer than the 1850-1900 pre-industrial level, indicating that temperatures had almost crossed the 1.5-degree Celsius threshold.
The Copernicus Climate Change Service speculates a likelihood of a 12-month period ending in January or February 2024 exceeding 1.5 degrees Celsius above pre-industrial levels.
Last year was the first time on record that each day within a year exceeded one degree Celsius above the pre-industrial level. About 50 per cent of all the days last year were more than 1.5 degrees Celsius warmer than pre-industrial levels.
Also, for the first time, two days in November had temperatures that were two-degree Celsius greater than pre-industrial levels.
The annual average air temperatures were the warmest, or close to the warmest, above large areas of all ocean basins and continents except Australia.
From June to December, each month was warmer than the corresponding month in any previous year.
The period from June to August 2023 was the warmest boreal summer season on record, and July and August were the warmest two months on record.
December 2023 was the warmest December ever, and saw an average temperature of 13.51 degrees Celsius, which is 0.85 degrees Celsius above the 1991-2020 average, and 1.78 degrees Celsius above the 1850-1900 level for December.

Sea surface temperature records in 2023
Global sea surface temperatures reached record-high levels from April through December.
Due to unprecedented sea surface temperatures, there were marine heatwaves in regions such as the Mediterranean, the Gulf of Mexico, the Caribbean, the Indian Ocean, the North Pacific, and the North Atlantic.
Antarctic sea ice reached record-low levels in February 2023.
In March, the Arctic sea ice extent reached its annual peak. However, in March 2023, the Arctic sea ice extent was among the four lowest for that time of the year in the satellite record.

Sea surface temperature records in 2023
Global sea surface temperatures reached record-high levels from April through December.
Due to unprecedented sea surface temperatures, there were marine heatwaves in regions such as the Mediterranean, the Gulf of Mexico, the Caribbean, the Indian Ocean, the North Pacific, and the North Atlantic.
Antarctic sea ice reached record-low levels in February 2023.
In March, the Arctic sea ice extent reached its annual peak. However, in March 2023, the Arctic sea ice extent was among the four lowest for that time of the year in the satellite record.

Greenhouse gas concentrations in 2023
The atmospheric concentration of carbon dioxide in 2023 was 419 parts per million (ppm), and that of methane was 1902 parts per billion (ppb), both record levels.
Carbon dioxide concentrations hD increased by 2.4 ppm from 2022 levels, and methane concentrations had increased by 11 ppb from 2022 levels.
The world saw several extreme weather events, including heatwaves, droughts, floods, and wildfires.
Hottest Year Ever: The year 2023 was the hottest ever, with global temperatures coming close to the 1.5-degree Celsius limit. The previous warmest year was 2016, but 2023 overtook 2016 as the hottest year ever after June 2023 saw unprecedented global temperatures, according to the European Union’s Copernicus Climate Change Service.
In 2023, daily global temperature averages had briefly surpassed pre-industrial levels by more than two degrees Celsius. Greenhouse gas concentrations, the El Niño phenomenon, and other natural variants are the major drivers behind the climate extremes observed in 2023.
El Niño began in July 2023, according to the World Meteorological Organization (WMO).
The Intergovernmental Panel on Climate Change (IPCC) considers 1850-1900 the pre-industrial period.
Temperature records in 2023
According to the European Union, the global average temperature in 2023 was 14.98 degrees Celsius. This was 0.17 degrees Celsius higher than the previous highest value in 2016, which was 14.81 degrees Celsius.
The year 2023 was 0.6 degrees Celsius wArmer than the 1991-2020 average, and 1.48 degrees Celsius warmer than the 1850-1900 pre-industrial level, indicating that temperatures had almost crossed the 1.5-degree Celsius threshold.
The Copernicus Climate Change Service speculates a likelihood of a 12-month period ending in January or February 2024 exceeding 1.5 degrees Celsius above pre-industrial levels.
Last year was the first time on record that each day within a year exceeded one degree Celsius above the pre-industrial level. About 50 per cent of all the days last year were more than 1.5 degrees Celsius warmer than pre-industrial levels.
Also, for the first time, two days in November had temperatures that were two-degree Celsius greater than pre-industrial levels.
The annual average air temperatures were the warmest, or close to the warmest, above large areas of all ocean basins and continents except Australia.
From June to December, each month was warmer than the corresponding month in any previous year.
The period from June to August 2023 was the warmest boreal summer season on record, and July and August were the warmest two months on record.
December 2023 was the warmest December ever, and saw an average temperature of 13.51 degrees Celsius, which is 0.85 degrees Celsius above the 1991-2020 average, and 1.78 degrees Celsius above the 1850-1900 level for December.
