Rising emissions and temperatures: The cost of Trump's climate retreat is now clear

The world is set to breach the critical 1.5-degree temperature limit, with Donald Trump's US withdrawal from climate action worsening the outlook, according to a UN report. But there is a small silver lining.

聯合國環境規划署最新報告顯示，1.5攝氏度升溫目標已無法實現，現行政策下本世紀將升溫2.8攝氏度。報告同時指出美國在特朗普政府退出巴黎協定、放松環境監管後排放增幅遠超其他國家，但碳定價等氣候政策已被證明有效。
