Projected temperature increase worldwide 2100, by scenario

Based on policies and actions in place as of November 2024, the global temperature increase is estimated to reach a median of 2.9 degrees Celsius in 2100. In the best-case scenario, where all announced net-zero targets, long-term targets, and Nationally Determined Contributions (NDCs) are fully implemented, the global temperature is still expected to rise by 1.9 degrees Celsius, when compared to the pre-industrial average. In 2015, Paris Agreement parties pledged to limit global warming to well below two degrees Celsius above pre-industrial levels, with the aim of reaching a maximum of 1.5 degrees. As of 2024, a warming of 1.2 degrees above the pre-industrial average was recorded.

根据截至2024年11月实施的政策和行动，全球气温上升预计在2100年将达到2.9摄氏度的中值。在最佳情景下，即所有宣布的净零目标、长期目标和国家自主贡献（NDCs）得到完全实施的情况下，与工业化前平均水平相比，全球气温预计仍将上升1.9摄氏度。2015年，巴黎协定各方承诺将全球变暖控制在工业化前水平两度以下，目标是最高不超过1.5度。截至2024年，记录的气温上升已达到工业化前平均水平1.2度。
