Whether climate change will be a source of yield uncertainty in the coming decades remains unclear as well. Although precipitation may be affected, higher temperatures would enable agricultural production in colder regions, and CO2 is known to bolster plant growth, even in dry areas.
气候变化是否会变成未来几十年产量不确定的来源，目前还不得而知。尽管降水量可能受到影响，但温度升高能让较冷地区适合农业生产，而二氧化碳能刺激植物生长，即使在干旱地区也是如此。
