UNITED NATIONS: The world is on a path to get 1.8°C 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 UN report said today.

Under every scenario, apart from the “most optimistic,” the chance of curbing warming so it stays within the internationally agreed-upon limit “would be virtually zero,” the UN’s Environment Programme’s annual Emissions Gap Report said.

Instead, the world is on track to get 3.1°C warmer this century.
