In his first public speech since leaving the White House, former US president Donald Trump has raised the climate issue while criticising his successor Joe Biden for rejoining the “very unfair” Paris Agreement, saying what good does it do when America is “clean” but China, Russia and India are not.

Speaking at the Conservative Political Action Committee in Orlando, Florida on Sunday, the 74-year-old leader, who left the White House on January 20, came down heavily on the Biden administration for putting the “United States back into the very unfair and very costly Paris Climate Accord without negotiating a better deal”.
