Line Plot from Scientific Research

This highlights the importance of early action to mitigate carbon emissions. The thick black line shows actual historical emissions. Dashed colored lines show past and future trajectories, respectively, to limit warming to 2 C, starting in different years. Each curve reflects a >66% chance of staying below 2 C using carbon budgets from the IPCC SR15 report 60 . This figure by Robbie Andrew is licensed under CC BY 4.0 (ref. 61 ).
