Climate crisis: carbon emissions budget is now tiny, scientists say

Having good chance of limiting global heating to 1.5C is gone, sending ‘dire’ message about the adequacy of climate action

The carbon budget remaining to limit the climate crisis to 1.5C of global heating is now “tiny”, according to an analysis, sending a “dire” message about the adequacy of climate action.

The carbon budget is the maximum amount of carbon emissions that can be released while restricting global temperature rise to the limits of the Paris agreement. The new figure is half the size of the budget estimated in 2020 and would be exhausted in six years at current levels of emissions.
