研究警告说,2°C的升温可能会导致比较高水平更严重的极端天气. Study warns 2°C warming may cause worse extreme weather than higher levels.

一项新的研究警告说,即使全球气温升高2摄氏度的目标也无法防止灾难性的极端天气事件如严重干旱和强降雨. A new study warns that even a 2-degree Celsius global warming target may not prevent catastrophic extreme weather events like severe droughts and intense rainfall. 研究人员发现, 某些气候模型预测2度的影响超过了高温水平所期望的影响, 威胁到粮食生产,森林和城市. Researchers found that some climate models predict impacts at 2 degrees that exceed those expected at higher warming levels, threatening food production, forests, and cities. 报告敦促各国政府为最坏的情况做好准备, 并制定应激测试适应计划. 因为目前政策预计将导致2. 3至2.5度的变暖. The findings urge governments to prepare for worst-case scenarios and stress-test adaptation plans, as current policies are projected to cause 2.3 to 2.5 degrees of warming.
