Nikki Haley claims Trump does believe "the climate is changing".

It has been hard to pin down whether Trump does or does not believe in climate change.

But to the regret of nearly all, U.S. President Donald Trump on Thursday announced that his country would withdraw from the Paris climate deal, which is regarded by many as the "best chance we have to save the planet".

U.S. Ambassador to the United Nations Nikki Haley speaks to the staff at the USA embassy in Ankara on May 23, 2017.

She added that the warming climate is "a big health issue for the air our children and grandchildren breathe". She was referring to statistics that Trump cited in announcing the US withdrawal and which are disputed by environmentalists, according to a report in the Washington Post.

"President Trump believes the climate is changing, and he believes pollutants are part of the equation", Haley said Saturday.

US President Donald Trump announces his decision to withdraw the US from the Paris Climate Accords in the Rose Garden of the White House in Washington, DC, on June 1, 2017. "The president made an executive agreement because that was the best that we could do", he said.

"When Donald Trump says to the world, well, we're going to negotiate a better deal... that's like O.J. Simpson saying he's going to find the real killer", Kerry said in an interview on NBC's "Meet the Press", alluding to the former American football star who was controversially acquitted of killing his former wife.

It has been hard to pin down his true beliefs on the subject. The United States is the second-largest emitter of greenhouse gases and this is the reason for which the president's choice is quite a blow to the global effort to fight climate change. But he backed away from saying to what extent he believed humans were responsible, adding that it "also depends on how much it's going to cost our companies".

"Everybody knows he isn't going to do that because he doesn't believe in it", Kerry continued.

Wallace and Stephanopoulos each pressed the administrator four times on their respective shows about whether Trump believed in climate change. "It's always changing. I've indicated the same".

As David G. Victor, a longtime scholar of climate politics at the University of California, San diego, has pointed out, "In cumulative terms, we (the United States) certainly own this problem (climate change) more than anyone else does".

"The President has indicated that climate changes", Pruitt said.
