There are no links, this is all from watching documentaries, and reading different magazines, and news papers.Please, why don't you just google,
"Earths oceans releasing Greenhouse methane", and Volcanoes releasing CO2,how it relates to "Earth cyclical climate change", also "How Sun Spot activity" has affected the Earth's overall temperature.You must also Google,
"Methane being released from melting Ice in the the North and south Poles",
how this has affected"Earth cyclical climate change". This, will provide you with all the "unbiased scientific information, that you require".
Get back to me on what you have found Chris.
