It finds every nation’s motion plans – referred to as Nationally Decided Contributions (NDC) – solely knock 7.5% off predicted 2030 emissions, however 55% is required to satisfy the 1.5C objective. Past 1.5C, extra extreme impacts of local weather change kick in, from excessive climate to rising sea ranges.

Piers Forster, local weather change professor at Leeds College, mentioned the report paints “an excessively bleak image”.

He mentioned: “It’s true that the 2030 emissions hole stays however if you happen to take a look at their numbers, it exhibits that the hole in long run emission targets is nearly closed.

“These nationwide plans present that the prices of motion are far lower than the price of inaction, so we now have all of it to play for at [COP26] to shut these gaps even additional.”

The report additionally highlights methods to slash emissions rapidly, together with by tackling the lesser talked about greenhouse gasoline methane by way of know-how and weight-reduction plan adjustments.
