Trump is not that much worse than Obama, it's mostly the media, politicians, people in power that are able to convince you of that. Remember, Obama droppee 26,000 bombs on Muslims last year, but I bet you'd never heard about a single one.

Climate Change is mostly about politics, just like the War on Poverty and War on Drugs. Yes it's real, just like people have real problems with poverty and drugs, but people starve and suffer in 2017 because of greed, which leads to politics, not because of resources. Climate Change will likely worsen the resource situation, but it's not actually the real problem with humanity. We need to get over our little egos and figure out how to get off this earth and keep exploring.
