Natan, I agree the article wasn't very good at pointing out if it was being sarcastic. Recall the talking point from the global warming skeptics: if global warming exists based on logical science and not the lies, we can accept that. We don't have to join the hysterical cult of doom, though, and a global warming future can be bright, not a nightmare. The problem has been, 99% of what we hear from promoting the idea of global warming, is the hysterical stuff. If Mental Floss has bought into the hysterical cult of global warming (I don't know), then maybe this article is trying to be clever and making fun of the talking point for global warming skeptics. Like this: 'Hey in the future, it's not all bad. You can enjoy your hot jellyfish soup on a nice balmy day in Greenland on the beach, watching the ships come in. Finish it off with a nice glass of meltwater that might give you smallpox. Hurry, though. The sun sets early because the mountains have grown so tall. Hopefully the fast moving satellites can avoid the tall mountains, otherwise you might not be able to catch today's small pox death toll on TV'.
