Stop with your preaching already, India has blocked the talks because developed countries have gone back on many of the promises they have agreed to keep including funding, technology transfer and their own commitments to reducing their emissions.
Preaching? Hardly. My first paragraph was all about how India is going to be one if the countries hit the hardest by climate change. Once you understand that, you have to try and come up for an explanation as to why they are acting against their own interest. India needs more developed countries to stop polluting, and I really don't see how throwing a spanner in the works does not seem to me to be a winning strategy for convincing the big polluters to stop. Maybe I'm wrong, maybe they have a really cunning plan, but we're talking about a country that got into a nuclear arms race with its neighbour, so I'm thinking that we're not talking about diplomatic geniuses playing a game if geopolitical chess. I would be happy to be wrong, but in the mean time my money is on the Indian government doing stupid things for base political considerations.
