How much CO2 can we still emit while limiting global warming to well below 2 °C?
Abstract
In December 2015, the Paris Agreement signed by 195 nations agreed to limit global warming "to well below 2 °C above preindustrial levels and to pursue efforts to limit the temperature increase to 1.5 °C." Since the amount of global warming is approximately proportional to cumulative CO2 emissions, such a warming limit corresponds to a remaining "CO2 budget" - a total amount of CO2 that can still be emitted world-wide. I will discuss current estimates of the size of this CO2 budget and what this means for the emissions trajectories compatible with the Paris Agreement.
