well lets hope i get laid before then....
but seriously, i dont believe it. it's gonna take a looong time before human life on this planet is erased, and that wont be until the sun expands and swallows most the planets in this solar system.
And i dont honestly believe that global warming is 100% true anyway, ya know.
There has been evidence that the suns solar flare activity has increased and, as with cycles that have happened before, the planet gets warmer when this occurs then cools down again once it stops. Thats my logic anyway.
