Yeah, but all it will take to cool things down again is another Tambora size eruption like in 1815, and another Krakatoa and things will chill down. A real big cool down would happen if the caldera under Yellowstone goes off. Even young generations of today would probably never see a tan if that one goes up. And from what the studies have shown, the super volcano goes off about 600,000 years, and the last time it went up was around 640,000 years ago. The eruption was so fowerful that it caused the surrounding mountain range to collapse into the caldera.

Here's a hypothetical film about it.



Or if say 3 volcanos have major eruptions over a ten to twenty year period, it will cool things down again to the equivilant of the little iceage again most likely. So between starvation and disease, the population will take a big hit most likely from it, as anywhere 1/3 to 2/3 of the world's population could be lost to such a disaster today.
