气候变暖将显著影响粮食产量
2025-06-23 00:06 by 巨龙之夜
根据发表于《自然》的全球作物产量分析，到本世纪末，每变暖 1℃，人均可用粮食每天将减少约121千卡。研究论文作者、美国伊利诺伊大学厄巴纳-香槟分校的 Andrew Hultgren 说，根据目前轨迹，在 3℃ 的变暖情景下，“这相当于每个人都不再用早餐”。Hultgren 和同事收集了世界上六大主粮作物的产量数据。这些作物提供了全球人类所需热量的 2/3 以上。他们发现，对于除水稻外的所有作物，高温会造成巨大的损失，因为水稻在更暖的夜晚生长得更好。根据预测，到本世纪末，全球变暖情况下玉米产量比没有全球变暖的情况下降 12% 或28%，具体下降程度取决于温室气体排放量是适中还是非常高。如果农民不采取措施适应气候变化，那么在本世纪末变暖程度高的情景下，作物损失将增加约1 /3。不过，研究人员指出，即便采取了上述农业适应措施，也不太可能弥补气候变化造成的巨大作物损失。

First methane-powered sea spiders found crawling on the ocean floor
Scientists on the US West Coast say they discovered three previously unknown species of deep-sea spider that could have a rare diet fueled by a common greenhouse gas.
