人類滅絕的10種可能 特朗普入圍

Climate change
氣候變化

Concentrations of carbon dioxide, released when fossil fuels are burned, as well as other 'greenhouse gases', have risen at an alarming rate, forming a thick blanket around Earth, trapping excess heat and nudging global temperatures upwards.
化石燃料燃燒釋放的二氧化碳以及其他“溫室氣體”的濃度以驚人的速度增加，厚厚地籠罩在地球周圍、吸收多余熱量、導(dǎo)致全球氣溫上升。

Scientists warn of a tipping point - a temperature beyond which the problem can no longer be dialled back.
科學(xué)家們提醒，溫度超過某個臨界點問題將無法挽回。

If we reach this point, a runaway greenhouse effect would cause temperatures to soar to several hundred degrees Celsius, boiling the oceans and making life on Earth impossible.
如果氣溫一旦達(dá)到了這個臨界點，那么失控的溫室效應(yīng)將會使氣溫飆升到幾百攝氏度，讓海水沸騰，地球上將無法生存。

However the CESR rates climate change as another low to medium risk priority.
不過，CESR也將氣候變化的風(fēng)險等級列為中低等。
