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。

"There are a lot of things that Telegram could have been doing this whole time. And they know exactly what they are and they've chosen not to do them. That's why I don't trust them," she said. Ukrainian forces successfully attacked Russian vehicles in the capital city of Kyiv thanks to a public tip made through the encrypted messaging app Telegram, Ukraine's top law-enforcement agency said on Tuesday. This provided opportunity to their linked entities to offload their shares at higher prices and make significant profits at the cost of unsuspecting retail investors. Investors took profits on Friday while they could ahead of the weekend, explained Tom Essaye, founder of Sevens Report Research. Saturday and Sunday could easily bring unfortunate news on the war front—and traders would rather be able to sell any recent winnings at Friday’s earlier prices than wait for a potentially lower price at Monday’s open. Despite Telegram's origins, its approach to users' security has privacy advocates worried.
