Global Climate Change
Climate change is the Big Kahuna of all scenarios in which our presence on Earth is ended. Despite what the climate change deniers would have you believe, climate change is real. It is being caused by human beings, with a little help from lots of cows emitting methane, plus that giant well of methane lurking under the Arctic ice. As we burn carbon and increase our meat-eating ways, more and more greenhouse gases are building up in the atmosphere. It is pretty easy to see the end game of this scenario. Result of this threat: death to everything.
