氣候變化

Climate change could bring near-unliveable conditions for 3bn people, say scientists
2070年或有30億人生活在極端高溫中

Each degree of warming above present levels corresponds to roughly 1bn people falling outside of ‘human niche’
氣溫比目前水準每升高一度,就意味著大約有10億人脫離宜居的「人類生態位」。

Up to 3bn out of the projected world population of about 9bn could be exposed to temperatures on a par with the hottest parts of the Sahara by 2070, according to research by scientists from China, US and Europe.

根據中國、美國和歐洲科學家的研究,到2070年,預計全球到時候擁有的90億人口中,有多達30億人可能生活在與撒哈拉最炎熱地區相同的氣溫下。
