It really isn't the smoke that causes the Global Warming but it is closely related.
The "warming" is actually caused by the HUGE FLAME that comes out of the barrel. If you don't believe me, fire off your trusty muzzleloader at night for some real impressive fireworks! :grin:
And don't fire them near a bale of hay or you will experience some local warming, good thing I had to pee... :rotf:
As for global warming, IF you could never get black powder any more, it will make billions of people world wide hot under the collar.
