President Donald Trump says he will again withdraw the United States, a top carbon polluting nation, from the landmark Paris climate agreement – dealing a blow to worldwide efforts to combat global warming.

The White House announcement, which came as Mr Trump was sworn in on Monday for a second term, echoed Mr Trump’s actions in 2017, when he announced that the US would abandon the global Paris accord.
