联合国:全球将升温2.7摄氏度

The world is squandering the opportunity to “build back better” from the Covid-19 pandemic, and faces disastrous temperature rises of at least 2.7C if countries fail to strengthen their climate pledges, according to a report from the UN.

联合国的一份报告指出，世界正在浪费新冠疫情带来的"重建"机会，如果各国依然无法兑现气候承诺，全球气温会上升至少2.7摄氏度，这将是灾难性的。

Tuesday’s publication warns that countries’ current pledges would reduce carbon by only about 7.5% by 2030, far less than the 45% cut scientists say is needed to limit global temperature rises to 1.5C, the aim of the Cop26 summit that opens in Glasgow this Sunday.

10月26日发布的这份报告警告称，各国目前的承诺如果能够兑现，也只能在2030年前将碳排放量降低7.5%左右，远远低于科学家所说的将全球气温升幅限制在1.5摄氏度以内所需的45%。将全球升温幅度控制在1.5摄氏度以内也是10月31日在格拉斯哥召开的Cop26联合国气候峰会的目标。

Emissions fell by about 5.4% last year during Covid lockdowns, the report found, but only about a fifth of the spending on economic recovery was geared to efforts that would cut carbon.

报告发现，去年疫情封锁期间，碳排放量大约减少了5.4%，但是经济复苏的资金中只有约五分之一用于减排需求。
