對於那些仍然懷疑全球氣候變化的人來說,這七張新圖表應該能消除他們的疑慮。 今天上午,政府間氣候變化專門委員會(IPCC)釋出了一項名為“氣候變化 2013:物理科學基礎”的六年研究的首份公開摘要。 摘要包含了報告中的圖表,並解釋了圖表背後的資料。 這些圖表作為一個整體,展示了過去幾十年來的明顯趨勢:全球許多地區的平均地表溫度升高了高達 2.5 攝氏度,全球海平面上升了 20 釐米,北極夏季海冰面積縮減了 400 萬平方公里,等等。

在為釋出詳細資訊而舉行的新聞釋出會上,瑞士伯爾尼大學的托馬斯·斯托克(Thomas Stocker),同時也是報告撰寫工作組的聯合主席,表示氣候變化是我們時代最嚴峻的挑戰,並補充說:“它威脅著我們的星球,我們唯一的家園。” 聯合國秘書長潘基文透過網路影片在新聞釋出會上發表講話,他說:“熱度已經來臨。我們現在必須行動。” 聯合國於 1988 年召集 IPCC,以評估地球氣候狀況以及人類活動對其造成改變的程度。 來自 39 個國家的 600 多位科學家作者評估了約 9,000 份同行評審研究和 54,000 條評論,最終形成了這份最新報告。
