And guess what....Volcanoes cause global cooling....
I thought I read that volcanoes do more to put carbon in the atmosphere than all human activity, ever.
The eruption of Laki on Iceland in 1783-84 caused a severe cooling which led to widespread crop failures and massive famine in Europe, India even widespread food shortages in the U.S.
today would prob be even worse due to huge number of people living in hunger , about 10% of the world.
