The world is on a path to get 1.8 degrees Celsius (3.2 Fahrenheit) warmer than it is now, but could trim half a degree of that projected future heating if countries do everything they promise to fight climate change, a United Nations report said Thursday.

But it still won’t be near enough to curb warming’s worst impacts such as nastier heat waves, wildfires, storms and droughts, the report said.

Under every scenario but the “most optimistic” with the biggest cuts in fossil fuel burning, the chance of curbing warming so it stays within the internationally agreed-upon limit “would be virtually zero,” the United Nations Environment Programme’s annual Emissions Gap Report said. The goal, set in the 2015 Paris Agreement, is to limit human-caused warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) since pre-industrial times.
