The goal of keeping long-term global warming to 1.5 degrees Celsius (2.7 Fahrenheit) is moving out of reach, according to climate experts, with nations failing to set more ambitious targets despite months of record heat on land and at sea. When envoys met in Bonn in early June to prepare for this year's November climate talks, the average global surface air temperature was more than 1.5°C above pre-industrial levels for several days, the EU-funded Copernicus Climate Change Service (C3S) said.
