President Trump has made sweeping changes to America's policies on climate since being sworn in 100 hundred days ago. He has announced plans to "unleash" American energy, including revitalising the coal industry and boosting oil and gas. The President has also cut funding for clean energy projects and renewables, while slashing jobs in government-funded climate research. Experts also say Washington's trade tariffs are having a big impact on the global market for new technologies such as solar panels and electric vehicles.

So what does all this mean for the green transition in America and beyond? In this show, Graihagh Jackson talks to the BBC's US Environment Correspondent Carl Nasman, BBC Climate Editor Justin Rowlatt and Zerin Osho, Director of the India Programme at the Institute for Governance & Sustainable Development based in Washington DC.

Graihagh also chats to Tom Di Liberto, a climate scientist who was recently fired from America's National Oceanic and Atmospheric Administration (NOAA).
