Re: More people are killed by cold weather than by heat.
All you need to do is raise the average temperature of the Earth by about 15C degrees to kill just about every species on the planet. Sure, humanity will find a way to survive the first round, and then we'll find out that there's not enough food left to feed 6 billion people, or even 1/100th of that number. No big deal, though, since 1% of the population - 60 million - is still a decent number, and we can make due with a scorched planet, right? Just don't go to the beach without your SPF10000 sunscreen. Sounds like a peachy future to leave our grandchildren.
