Can the earth's hot iron core pulsating and belching volcanoes and warming the oceans cause global warming?

Answer 1

Volcanic events aren't associated with the earths core. They are caused by tectonic events. When plates move on a molten 'river' of magma beneath them they produce subduction zones where one plate travels beneath another. This, in turn, causes friction which then causes high heat. Where this zone ends this heat and friction causes one type of volcano...called a strato volcano. The material of the magma is generally types of granite which originates from the runoff of continental material brought to the oceans by rivers. Another type of volcano is a 'shield' volcano, caused by a 'hot spot' and is formed from basalt (which originally is ocean bottom). The Hawaiian Islands are a good example which is still active. Still another example is Yellow Stone Park in the USA. The plate on which it is located is traveling over a 'hot spot', and a large pool of hot magma is beneath this area, called a 'batholith'. This is why 'Old Faithful', and the 'boiling paint pots', etc.
Global warming is not new to geologic history. Many times in geologic time the earth has experienced it. BUT, humans and industry have added to what was once caused by volcanic debris in the atmosphere.
The latter type will always be present and produce a type of 'global warming', but the former [us] can be controlled.....it's just a matter of money/power, and other human weaknesses...

Answer 2

The release of Carbon Dioxide from volcanoes contributes;
so would water vapour, released from underground streams, & evaporated when hot lava hits the sea-water.
But volcanic ash forms clouds which shade the earth.
This would have a cooling effect in the longer term.

Answer 3

No... the earths core does not make global warming. Maybe you should try doing some research on the subject its a rather simple concept.... this is one of the most ridiculous things I've seen today...
