Actually it could be the end of the world: there are scientists who believe that we have less than ten years to stop climate change which will certainly be the end of us. Denying climate change out of one's uninformed noggin for no reason other than that reality gets in the way of your profits and, also, being the president of the United States of America who offs NASA Earth services and the Paris Climate Agreement among other things then, that potentially makes you the worst man in history because of the number of people who will certainly die as a result. 
Science...its that thing we do to observe God's creation...sometimes mistakes are made but scientists try to avoid that as it is to no-one's best interest....Your life is at stake because of this person as are everyone else's. Then there is the issue of Trump's denial of Russia's danger to the United States...he's a dictator who abused our democracy. Really...Then there's the Geneva Convention and torture....you're not concerned?
