If global warming is a result of geophysical factors ocurring within the Milankovitch cycle when strata volcano weren't extinct but caused the last ice age is there a chance that strata volcanos might errupt again under the same geodetic position and climate conditions?.

I think the answer is Yes. A super volcano in Indonesia, Toba, is thought to have erupted about 74,000 years ago and blanketed the Earth with clouds that cooled the Earth and led to major extinctions. Volcanos are also credited with ending ice ages, by filling the atmosphere with C02, a greenhouse gas, and raising the temperature enough to melt the ice. Interesting question!

good answer jxt :). The last Toba eruption was resposible for a mass extinction of some 75% off all above ground organisms. There is also Yellowstone National Park, another huge super volcano. Volcano's like that have the ability to produce 2500 cubic miles of ash and debris. Compare that to Mt. St. Helens in 1980, it produced about 2 cu. mi of ash and debris. Events like that are rare, but change the planet conciderable when they do happen.

Right now vulcanologists are afraid that the Yellowstone super volcano could erupt and that would cause a huge mass of gas and melted rock to be thrown at 25 km into the atmosphere, blocking the sun, which could cause the extinction of 90 procent of lifeforms to disappear not to the eruption itself but to the ICE AGE caused by that .Ironic isn't it?

Also if a volcano can perpetuate global warming, the ice caps would melt into the oceans, cooling the jet stream, bringing less warm water north and that could conceivably cause an ice age.

It could put enough ash and small particles into the air to block heat from the sun, and cause ice ages. Look at the Yellowstone caldera.

yeah it can, it did several hundered years ago. By blocking out the sun with dust and debris.

yes they can if their ash is in the atmosphere for longer then a thousend years.
