A volcano can actually do it....
Why aren't the environmentalists crying foul now, especially with all that poisonous gas been emitted into the atmosphere!
Volcano's are by far the worst ozone terrorists around!
*eyebrow raise.* What are you gonna do, put a cork in it?
Maybe we can plug it up with Hummers.
Volcanoes actually can give a short term reprieve or offset from 'global warming' effects, though they of course cause other conditions that are not so lovely, and, of course, they don't actually stop the carbon buildup from going on, either. Once the volcanic stuff falls out, you're pretty much right back to the warming. Like with Pinatubo.
Only problem is, all the while, the denier crowd are saying the volcano's short term effects mean nothing needs doing at all.
Volcanic glacier melt isn't a lot of fun to be downstream of, what with lahars and all, but that doesn't mean that volcanoes have somehow been causing the Arctic sea ice and the glaciers to melt and thin. Hot lava does of course, often melt a volcano's own ice cover, but that's a very localized phenomenon, not a global one.
There could indeed be a cold year or two in the Northern hemisphere. I don't know what effect that may have on arctic conditions, but it could help there for a while. Or not.
