Some 73% of people now believe that Earth's climate is approaching abrupt and irreversible "tipping points" due to human activity, according to a global opinion poll released Tuesday.

8月17日公布的一項全球民意調(diào)查顯示，大約73%的受訪者認(rèn)為，人類活動正將地球氣候推向嚴(yán)峻和不可逆轉(zhuǎn)的"臨界點"。

The survey showed that more than half (58%) of respondents in G20 nations feel very or extremely concerned about the state of the planet.

調(diào)查顯示，G20國家中超過一半(58%)的受訪者對地球現(xiàn)狀感到非?；驑O其擔(dān)憂。

Scientists are increasingly concerned that some feedback loops in nature - such as irreversible melting of ice sheets or permafrost - may be close to being triggered as mankind's carbon emissions show no signs of slowing.

科學(xué)家們越來越擔(dān)心，由于人類碳排放依舊沒有放緩跡象，自然界的"反擊行為"將接踵而至，比如冰原或永久凍土的不可逆轉(zhuǎn)的融化。

The IPCC report warned that Earth is on course to be 1.5 C hotter than pre-industrial times around 2030 - a full decade earlier than it projected just three years ago.

聯(lián)合國政府間氣候變化專門委員會此前發(fā)布的報告顯示，到2030年前后，地球氣溫將比工業(yè)化前高出1.5℃，比3年前的預(yù)測提前了整整10年。

Tuesday's survey showed that people in developing nations were more likely to be willing to protect nature and the climate than those in richer countries.

民調(diào)還發(fā)現(xiàn)，發(fā)展中國家比富裕國家的人更愿意為保護(hù)自然和氣候貢獻(xiàn)力量。
