For those looking for lessons in Indian diplomacy, Cancun hit a high-water mark. The reason was Jairam Ramesh.  The Mexicans found their mojo and India finally emerged as a climate winner.

People will be discussing the Copenhagen climate conference for years to come. Opinions will be mixed as to whether it was a step forward or a failure. Only history will tell whether it was a turning point or a tipping point.

From a ringside view from one who was there, the feeling today is of anger and disappointment.  The Copenhagen Accord may well prove to be the Munich Agreement of modern times. An appeasement to major emitting nations that condemned the world to runaway climate change and declared war on our children.

The moment of truth has arrived. Today will reveal whether the world will be able to 'Seal the deal' on climate change in Copenhagen. After two years of negotiations, now is the time we will see how serious our leaders are in addressing the greatest crisis facing humanity and our natural world: climate change.

India's opening gambit for the Copenhagen climate summit is now clear. Renamed 'Hopenhagen' for the duration of the UN climate summit starting next week, the Danish capital will now receive an Indian delegation with a target and a plan.
