The world is reneging on the promises made 22 years ago

The Independent, 21 December 2014:

Your article states “More and more countries are now taking climate crisis seriously” (“Rich square up to poor at climate talks”, 14 December). It is worth recalling that world leaders all agreed to prevent dangerous anthropogenic climate change as long ago as 1992, at the Earth Summit in Rio. Since then, annual emissions of carbon dioxide have increased by 60 per cent, the United States has refused to ratify the Kyoto Protocol, Canada has withdrawn from the protocol, and China has become the largest emitter on the planet. In truth, the world is reneging on the promises made 22 years ago.
