Emission trajectories needed to achieve the Paris Agreement's two-degree target without negative emissions, depending on the emission peak.
Evolution of land and sea temperatures 1880-2020 compared to the 1951-1980 average.

The two degree target is the international climate policy goal of limiting global warming to less than two degrees Celsius by 2100 compared to the pre-industrialization level. It is an integral part of the Paris climate agreement.[1] This objective is a political determination based on scientific knowledge concerning the probable consequences of global warming, which dates from the Copenhagen Conference in 2009.[2] It is criticized as insufficient,[1][3] because even a warming of two degrees will have serious consequences for humans and the environment, as demonstrated in particular by the IPCC Special Report on the consequences of a global warming of 1,5°C.
