Estimated change in global surface temperature 2021-2100, by scenario

As of 2021, global surface temperatures will continue to increase until at least the mid-century under all emissions scenarios. Crossing the 2°C global warming level in the mid-term period (2041–2060) and long term period (2081-2100) is likely to occur in the intermediate, high, and very high GHG emissions scenarios.

截至2021年，在全球所有排放情景下，地表温度将持续上升，直至至少世纪中叶。在中长期（2041-2060年）和长期（2081-2100年）期间，跨越2°C的全球升温阈值在中等、高以及极高温室气体排放情景下均有可能出现。
