2024 first year to pass 1.5C global warming limit
The planet has moved a major step closer to warming more than 1.5C, new data shows, despite world leaders vowing a decade ago they would try to avoid this.
The European Copernicus climate service, one of the main global data providers, said on Friday that 2024 was the first calendar year to pass the symbolic threshold, as well as the world's hottest on record.
This does not mean the international 1.5C target has been broken, because that refers to a long-term average over decades, but does bring us nearer to doing so as fossil fuel emissions continue to heat the atmosphere.
"We must exit this road to ruin - and we have no time to lose," he said in his New Year message, calling for countries to slash emissions of planet-warming gases in 2025.
Global average temperatures for 2024 were around 1.6C above those of the pre-industrial period - the time before humans started burning large amounts of fossil fuels - according to Copernicus data.
