October 2023, the Hottest October Worldwide

October 2023 has been declared the “hottest October ever recorded worldwide,” continuing a series of monthly records that began in June, according to the European Copernicus observatory. This year, 2023 is expected to “almost certainly” surpass the previous annual temperature record set in 2016 by the European Copernicus service, with temperatures surpassing previous records.

October 2023 exceeded the previous monthly temperature record by 0.4 degrees Celsius, set in 2019, and was 1.7 degrees higher than the pre-industrial period from 1850 to 1900, making it the warmest October in the last 220 years.

The period of June, July, and August 2023 exceeded the temperature record by 0.66 degrees. Scientists suggest that this year is on track to become the hottest not only since the beginning of meteorological measurements but also in the last 125,000 years.

Last month, October shattered the previous October temperature record, set in 2019, by a significant margin, according to the EU’s Copernicus Climate Change Service (C3S). “The record was exceeded by 0.4 degrees Celsius, which represents a huge margin,” said Samantha Burgess, Deputy Director of C3S, who described the October temperature anomaly as “extremely extreme.”

The heat is a result of continuing greenhouse gas emissions from human activity, combined with the emergence of the El Niño meteorological pattern this year, which warms surface waters in the eastern Pacific Ocean. Globally, the average surface air temperature in October was 1.7 degrees Celsius higher than the same month in the 1850-1900 pre-industrial period. The October record implies that 2023 is now “almost certain” to be the hottest year on record, according to C3S. The previous record was set in 2016, another El Niño year.

It is clear as day that these heatwaves result in droughts, famine, devastating wildfires, or more intense hurricanes, confirming scientists’ warnings on climate change.
