Donald Trump fighting climate change.

The election of a U.S. president who has called global warming a "hoax" raised questions Wednesday about America's involvement in the Paris Agreement on climate change — and the future of the deal itself.Several scientists warned that Earth will likely reach dangerous levels of warming if president-elect Donald Trump fulfills his campaign pledges to undo the Obama administration's climate change policies.

Many people at UN climate talks in Morocco said it's now up to the rest of the world to lead efforts to rein in greenhouse gas emissions. Others held out hope that Trump would change his stance and honour U.S. commitments under the Paris Agreement."Even he does not have the power to amend and change the laws of physics, to stop the impacts of climate change, to stop the rising sea levels."
