The centre came up with the 2C figure by comparing last week's surface air temperatures from ERA5 to those from 1850 to 1900. The service uses a model, known as ERA5, which provides hourly estimates of atmospheric, land and ocean data from 1940 to the present. ![]() The figure was calculated by the European Centre for Medium-Range Weather Forecasts through one of its observational programmes, the Copernicus Climate Change Service. The world's governments came up with the Paris Agreement in 2015 to keep global average warming to well below 2C, and ideally lower than 1.5C.īreaching the 2C threshold for a few days is not the end of the world, experts say, but it is just another sign of how much the planet is warming.Īnd it comes at a time when countries are preparing to meet at the United Nation's 28th Climate Change Conference (COP28) to discuss fossil fuel reduction.Ī complex topic when coal production is expected to increase to 2030, and oil and gas production to 2050 and beyond. The pre-industrial period was a time before widespread fossil fuel use.īurning fossil fuels has pumped substances like carbon dioxide (CO2) into the atmosphere, trapping heat at the planet's surface as part of the greenhouse effect. On November 17 and 18, the world was, on average, 2 degrees Celsius warmer than pre-industrial levels for the first time in modern recorded history. ![]()
