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日公布的一项全球民意调查显示，大约73%的受访者认为，人类活动正将地球气候推向严峻和不可逆转的"临界点"。

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

调查显示，G20国家中超过一半(58%)的受访者对地球现状感到非常或极其担忧。

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.

科学家们越来越担心，由于人类碳排放依旧没有放缓迹象，自然界的"反击行为"将接踵而至，比如冰原或永久冻土的不可逆转的融化。

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.

联合国政府间气候变化专门委员会此前发布的报告显示，到2030年前后，地球气温将比工业化前高出1.5℃，比3年前的预测提前了整整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.

民调还发现，发展中国家比富裕国家的人更愿意为保护自然和气候贡献力量。
