根据德国波茨坦气候影响研究所的一项研究,如果日常气温攀升到30摄氏度以上,玉米和大豆庄稼将减产5%。玉米植株对热浪和干旱尤其敏感。如果气温以这一速度持续升高,小麦、大豆和玉米未来的收成会减少50%。
8 Orchard Fruits 果园的水果
Peaches and cherries, two favorite stone fruits of the summer season, may in fact suffer at the hands of too much heat.
过热的天气可能会让夏季最受喜爱的两种核果——桃子和樱桃减产。
According to David Lobell, deputy director of the Center on Food Security and the Environment at Stanford University, fruit trees (including cherry, plum, pear, and apricot) require "chilling hours"— a period of time when they're exposed to temperatures below 45° F (7° C) each winter. Skip the required cold, and fruit and nut trees struggle to break dormancy and flower in the spring. Ultimately, this means a drop in the amount and quality of fruit that's produced.
斯坦福大学食品安全和环境中心副主任戴维·罗贝尔称,水果树(包括樱桃、李子、梨和杏)需要“冷冻期”——每年冬天气温低于7摄氏度的一段时间。如果没有这段冷冻期,核果树将无力打破冬眠期,在春天绽放花朵,最终将会导致果实减产,品质下降。
By the year 2030, scientists estimate the number of 45°F or colder days during winter will have lessened significantly.
