As envoys gathered in Bonn in early June to prepare for this year’s annual climate talks in November, average global surface air temperatures were more than 1.5C above pre-industrial levels for several days, the EU-funded Copernicus Climate Change Service said.
As climate envoys from the two biggest greenhouse gas emitters prepare to meet next month, temperatures broke June records in the Chinese capital Beijing, and extreme heatwaves have hit the United States. Countries agreed in Paris in 2015 to try to keep long-term average temperature rises within 1.5C, but there is now a 66% likelihood the annual mean will cross the 1.5C threshold for at least one whole year between now and 2027, the World Meteorological Organization predicted in May.High land temperatures have been matched by those on the sea, with warming intensified by an El Nino event and other factors.
Warmer seas could also mean less wind and rain, creating a vicious circle that leads to even more heat, said Annalisa Bracco, a climatologist at the Georgia Institute of Technology. The Worldwide Fund for Nature, however, warned of a “worrying lack of momentum” during climate talks in Bonn this month, with little progress made on key issues like fossil fuels and finance ahead of November’s COP28 climate talks in Dubai.
