The US has begun the process of withdrawing from the Paris Agreement, as other countries expressed regret and disappointment at the move.

The Trump administration formally notified the United Nations on Monday of its intention to exit the deal.

The notification begins a one-year process of exiting the global climate change accord, culminating the day after the 2020 US election.

The agreement brought together 188 nations to combat climate change.

It committed the US and 187 other countries to keeping rising global temperatures below 2C above pre-industrial levels and attempting to limit them even more, to a 1.5C rise.

The decision to withdraw - taken by President Donald Trump - made the US the world's sole non-signatory and prompted high-level efforts by the European Union to keep the agreement on track.
