11月25日、米欧豪などの26名の気候学者がIPCC以降の状況について、最新の観測結果や研究を元に、”気候変動は急速に顕在化し。緊急の削減策が必要”という提言を行いました。
発表されたリポートは、Copenhagen Diagnosis。コペンハーゲンでまもなく開催されるCOP15(気候変動枠組み条約締約国)を前に、このままでは、欧州などが目標としてる温暖化を2度までに抑えることはむずかしく、2100年に7度も上昇することを警告する内容になっています。リポートの全体は、

Global ice-sheets are melting at an increased rate; Arctic sea-ice is disappearing much faster than recently projected, and future sea-level rise is now expected to be much higher than previously forecast, according to a new global scientific synthesis prepared by some of the world’s top climate scientists.
In a special report called ‘The Copenhagen Diagnosis’, the 26 researchers, most of whom are authors of published IPCC reports, conclude that several important aspects of climate change are occurring at the high end or even beyond the expectations of only a few years ago.
The report also notes that global warming continues to track early IPCC projections based on greenhouse gas increases. Without significant mitigation, the report says global mean warming could reach as high as 7 degrees Celsius by 2100.
The Copenhagen Diagnosis, which was a year in the making, documents the key findings in climate change science since the publication of the landmark Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report in 2007.
The new evidence to have emerged includes:
・Satellite and direct measurements now demonstrate that both the Greenland and Antarctic ice-sheets are losing mass and contributing to sea level rise at an increasing rate.
・Arctic sea-ice has melted..........

" 米欧豪などの科学者は25日、地球温暖化により今世紀末までに最大で気温が7度、海面が2メートル上昇する恐れがあるとの報告書を発表した。最新データの分析から、2007年の気候変動に関する政府間パネル(IPCC)第4次報告書の予測を上回る速度で温暖化が進んでいることが明らかになったという。
