President-elect Trump has called climate change a Chinese hoax, vowed to dismantle America's climate and clean energy policies, and appointed climate deniers with ties to the fossil fuel industry to his transition team and Cabinet.

In response, more than 800 Earth science and energy experts in 46 states have signed an open letter to Donald Trump, urging him to take six key steps to address climate change to help protect “America’s economy, national security, and public health and safety.”

The release of this open letter is accompanied by a public petition, which can be signed at Change.org.
