Copernicus Confirms New Record - 2023 Global Temps 1.48C Above Preindustrial Baseline

2023 “smashed” the record for the hottest year by a huge margin, providing “dramatic testimony” of how much warmer and more dangerous today’s climate is from the cooler one in which human civilisation developed. The planet was 1.48C hotter in 2023 compared with the period before the mass burning of fossil fuels ignited the climate crisis. The figure is very close to the 1.5C temperature target set by countries in Paris in 2015, although the global temperature would need to be consistently above 1.5C for the target to be considered broken.

Scientists at the EU’s Copernicus Climate Change Service (CCCS) said it was likely the 1.5C mark will be passed for the first time in the next 12 months. The average temperature in 2023 was 0.17C higher than in 2016, the previous record year, marking a very large increase in climate terms. The primary cause of this increased global heating was continued record emissions of carbon dioxide, assisted by the return of the natural climate phenomenon El Niño.

The high temperatures drove heatwaves, floods and wildfires, damaging lives and livelihoods across the world. Analysis showed some extreme weather, such as heatwaves in Europe and the US, would have been virtually impossible without human-caused global heating.

The CCCS data also showed that 2023 was the first year on record when every day was at least 1C warmer than the 1850-1900 pre-industrial record. Almost half the days were 1.5C hotter and, for the first time, two days were more than 2C hotter. The higher temperatures increased from June, with September’s heat so far above previous averages that one scientist called it “gobsmackingly bananas”.
