Yesterday EU scientists said that 2023 is set to be the world’s warmest in 125,000 years, after data showed last month was the hottest recorded October by a large margin.
Last month crossed the previous highest October mean temperature, from 2019, by 0.4 degrees Celsius, the EU’s Copernicus Climate Change Service (C3S) Deputy Director Samantha Burgess said, describing the temperature anomaly as “very extreme”. This has resulted in 2023 as a whole “virtually certain” to be the warmest year captured. The heat is a consequence of continued greenhouse gas release from burning of fossil fuels, added to the naturally occurring El Nino climate pattern, which warms the surface waters in the eastern Pacific Ocean. The latest hottest year on record is 2016, which is also an El Nino year, although 2023 is on track to surpass that.
