Only five years left before 1.5°C carbon budget is blown

Only five years left before 1.5°C carbon budget is blown

In its most recent synthesis report, published in early 2014, the Intergovernmental Panel on Climate Change (IPCC) laid out estimates of how much CO2 we can emit and still keep global average temperature rise to no more than 1.5C, 2C or 3C above pre-industrial levels.

That same year, Carbon Brief used these estimates to calculate how many years of current emissions were left before blowing these budgets.

Updating this analysis for 2016, our figures suggest that just five years of CO2 emissions at current levels would be enough to use up the carbon budget for a good chance – a 66% probability – of keeping global temperature rise below 1.5C.
