聯合國:溫室效應氣體濃度達創紀錄水平

The United Nations says surging carbon dioxide emissions sent greenhouse gases in the atmosphere to record levels last year.

In its annual report on greenhouse gas concentrations Tuesday, the World Meteorological Organization said carbon dioxide levels between 2012 and 2013 marked the largest yearly increase since reliable global records began 30 years ago.

A large percentage of carbon dioxide emissions are absorbed by the oceans.

In a statement accompanying the report, WMO chief Michel Jarraud warned that "past, present and future carbon dioxide emissions will have a cumulative impact on global warming and ocean acidification." He said the "laws of physics are non-negotiable."

Many scientists believe that increased greenhouse gases are responsible for global warming, or the warming of the atmosphere. Jarraud has said there is no doubt that global temperatures are rising.聯合國說，二氧化碳排放量急劇增加，大氣層中的溫室效應氣體去年達到創紀錄水平。

世界氣象組織星期二發表的溫室氣體濃度年度報告說，自30年前開始有效記錄全球大氣層二氧化碳含量以來，2012年至2013年的二氧化碳增長幅度達到最高點。

排放的二氧化碳一大部分被海洋吸收。

世界氣象組織祕書長雅羅同時發表聲明說，“過去、現在和將來的二氧化碳排放 將對全球變暖和海水酸化產生累積影響。”他說，“物理定律是不容置疑的。”

很多科學家認爲溫室效應氣體增加是導致全球變暖或大氣層變暖的原因。雅羅曾經表示，全球氣溫毫無疑問是在不斷增高。
