World leaders adopt 2℃ climate warming limit

摘要

The G8 and major developing countries have agreed on the need to limit global warming to 2℃. G8 leaders agreed to cut their emissions by 80% by 2050, but their inability to agree nearer-term targets left developing countries unwilling to commit to a crucial 50% global reduction target for 2050.rnLeaders of the G8 group of developed nations and the largest developing countries meeting at l'Aquila, Italy, on 8-9 July agreed on the need to limit global warming to below the 2℃ necessary to reduce risks of dangerous climate change. This is a crucial first step in agreeing global targets for greenhouse gas cuts.
