Eh, you're overreacting. All Algore and his acolytes are saying is that after all of the Global Warming induced earthquakes, what's left of the world will be consumed in flames from Global Warming, then the flames will be quenched by hurricanes - also caused by Global Warming. Then we'll all freeze to death. The cause? Global Warming. And, more important, it all can be avoided, if only we do exactly as AlGore saith. Praise be unto Al.
At best, it's a mild overstatement. A trivial inaccuracy. A minor error if, a couple of centuries from now, it's found not to be true.
do i need a sarcasm tag?
That depends on whether you really believe it or not....
