UNUnited Nations says, 30 States would formally join the Paris Agreement on climate change, moving it closer to reality. It said countries including Argentina, Brazil and Mexico, Bangladesh, Singapore, Thailand and United Arab Emirates would submit their ratification today at the UN General Assembly.

The Paris Accord, sealed last year commits countries to make plans to keep global warming at no more than two degrees Celsius (3.6 Fahrenheit) above pre-industrial levels to try to avoid the worst effects of climate change.

According to the UN Framework Convention on Climate Change, to take effect, 55 countries responsible for global emissions of greenhouse gases must join the Accord.

The agreement received a major boost earlier this month when China and the United States, the two largest emitters, jointly acceded to the deal during a summit between US President Barack Obama and and his Chinese counterpart Xi Jinping.
