In Montreal, a UN conference on climate change has marked its first significant victory after an all-night session of talks strove to ensure that an extension to the two weeks of negotiations was not in vain.It appears the delegates have made the most of the extra time they gave themselves to reach agreement. They have forged a deal to extend the Kyoto accords beyond their 2012 expiry date, and finally brought America onside to take part in new talks on climate change. The Kyoto extension on limits and reductions on greenhouse gas emissions is important. In seven years time, without a deal, there might have been a free-for-all. Delegates have also approved a new global dialogue to tackle climate change, talks that will include America. The agreement appears to hit the conference’s target of ensuring that the next battle plans in the war on climate change be drawn up now, rather than later, and in haste.
