I used the "Nuclear Winter" analogy because it is a commonly known phenomena. A volcanic event with a VEI of 6, 7, or 8 will most likely affect world wide weather conditions.

See: :http://volcano.und.nodak.edu/vwdocs/eruption_scale.html Nothing there that talks about weather effects. It merely defines the scale. Since there have been 6 and 7 eruptions in recorded history, whatever effect they have on "world wide weather conditions" is known, minor, and transient. All the nuclear weapons in the world are not enough to create 'Nuclear Winter', by the way. The authors cheated the numbers. -- "Ignorance is preferable to error, and he is less remote from the truth who believes nothing than he who believes what is wrong." -- Thomas Jefferson |
