I came across a couple of great comics the other day – one that shows climate change over many millenia (http://xkcd.com/1732/) and another that I think is related, about surviving in a post-apocalyptic world (http://www.newyorker.com/culture/culture-desk/the-life-changing-magic-of-decluttering-in-a-post-apocalyptic-world). I recommend them to people to check out for some info, and for a bit of fun.
