Will climate change stop us getting any taller?
气候变化会阻碍人类长高吗？
文字稿
For around 150 years, humans have been getting taller.
在过去约 150 年间，人类的身高一直在增长。
But that trend could be coming to an end.
但这一趋势可能即将止步于此了。
Researchers analysed 200,000 children in South Asia, a region particularly vulnerable to the effects of climate change.
研究人员分析了 20 万名南亚儿童的数据，这一地区极易受到气候变化的影响。
They estimated that children who had experienced temperatures above 35C coupled with high humidity during every trimester while they were in their mothers’ wombs, would be 13% shorter than expected for their age.
据他们估算，这些儿童在母亲子宫中时，如果在妊娠期的每个阶段都经历了 35 摄氏度以上的气温以及高湿天气，那么他们的身高就会比同龄人的预期值低 13%。
Height is strongly determined by genetics and nutrition, but the study suggests that heat and humidity also play a part.
身高在很大程度上由基因和营养条件决定，但这项研究表明，高温高湿环境也会影响身高。
And researchers say that while the global picture remains uncertain, we could reasonably expect to see similar results in other parts of the world too.
研究人员还表示，虽然全球整体情况尚不明确，但我们有理由推测在世界其它地区也会发现类似的结果。
So, climate change might not just reshape the planet, but the size of the people living on it.
因此，气候变化可能不仅在重塑地球本身，也在改变人类的身材。
