“IMO, comparing ‘Global Warming’ to the eruption of Toba is lunacy. “
No not really volcanic ash would spread all over the world and block out the sun which in turn would cause global cooling. Just like pulling an awning out over a house what happens it cools off under the awning.
What I doubt or would doubt is the validity of a super volcano happening or did one happen all they know is they think they are possible none have been recorded that I know of. Have you? Enough Said
Blast From The Past
(Click then go to the site and click on ' launch interactive' to see all the known super-volcanoes)
"The most recent one (Taupo, in New Zealand) occurred 26,500 years ago. One from 74,000 years ago (Toba, in Indonesia) left behind a caldera, or giant crater, about the size of Rhode Island. The biggest one yet identified (La Garita, in Colorado) coughed out 1,200 cubic miles of volcanic materials. On this map, sample a selection of the aptly named, though thankfully extremely rare, natural cataclysms known as "supereruptions."—Peter Tyson"
There’s ample evidence of supervolcanic eruptions all over the world.
None have occured in recorded history, but the evidence is pretty obvious from ash deposits, etc.
