NPJ: CO2移除增加印度夏季干旱的风险（图）
CO2移除 印度 夏季干旱
2023/3/8
工业革命以来，大量排放的CO2通过温室效应造成全球变暖，对气候和人类社会造成严重广泛且不可逆的影响，如海平面上升、海冰融化、频繁的热浪等。为缓解这些影响，《联合国气候变化框架公约》在2015年制定了《巴黎协定》温升目标。科学研究表明，《巴黎协定》温升目标的实现需要应用CO2移除方法使CO2浓度在本世纪下降。如果应用CO2移除方法，气候系统恢复的速度和程度如何呢？IPCC AR6报告指出，CO2浓度...
在气候变化背景下，北半球的中高纬度地区（>23.7°N）经历了大气CO2浓度的快速增加，显著高于全球平均水平。然而大气CO2浓度这种非均匀空间分布如何影响北半球碳循环仍存在很大不确定性。最近，中国科学院大气物理研究所东亚区域气候-环境重点实验室丹利研究员团队的彭静针对大气CO2浓度空间分布如何影响陆地生态系统碳汇进行了系统研究。
