Trump wants to promote the dying coal industry in the face of overwhelming evidence of the effects on the planet, all to help out the fossil fuel industry. This is an excellent New York Times writeup.

Trump claims that global warming is a "hoax" perpetuated by the Chinese, even though China has invested $400 billion over the next three years to install renewable energy. (Source) Or how about the fact China has installed more solar panels than all other countries combined. (Source)

But seriously, why should Trump let facts get in the way of his argument?¯\_(ツ)_/¯
