India ratifies Paris climate change deal

India, the world's third largest emitter of greenhouse gases, formally joined the Paris agreement on tackling climate change on Sunday. India had called for more work on the agreement ahead of its ratification on Sunday, with its environment ministry saying the agreement laid a "broad framework" but detailed guidelines and rules were needed for it to become operational. The deal, agreed by nearly 200 countries, aims to slash greenhouse gas emissions by shifting away from fossil fuels to limit global warming to "well below" two degrees Celsius compared to pre-industrial times. But it needs to be formally ratified by countries representing at least 55 percent of global carbon dioxide emissions. Next week the European Union is expected to complete the joint ratification of the climate pact by its 28 member states - it would take approvals past the 55 percent mark and put the deal into effect ahead of the next round of climate talks in November, in Morocco.
