Sorry Captain, but I've put data and names twice on this subject: Volcanos are not the problem they are natural events and bear no part of the pre-industrial vs today's climate controversy. They have been eruptions forever and will do so in the future they are considered into the natural order of things (think of Pompeii (Mount Versuvius ), Tambora, Indonesia, etc.)). Scientist: volcanologists, climatologists etc. factor these things into the equation.
It's unnatural occurrences that are the problem and the majority are removable or at least vastly reduced.
The freezing of polar ocean surfaces and defrosting is not a problem either that's just replacing a form of water back into its origin. It is land ice defrosting that is the problem. it is additional water adding and raising the levels of the oceans Rainwater is a normal replacement of evaporation which is a mixture of both ocean water and rain from the land, a cycle event, think of a revolving door, or of this never ending discussion.
Land ice melting into the ocean from the polar caps is an addition and it consists of trillions of mega tons of ice that acts as a reflective shield from the heat of the sun. Lessoning that shield will cause the heat to be absorbed into the oceans and the land instead of being reflected back into space and raise the levels of parts of the ocean, thus causing loss of land mass and heating both land and oceans.
My reoccurring bouts of masochism have ended.
