I saw this theory floating around. Haven't done much research but it sounds "plausible". Could Siberia warming be due to the ocean around it heating? The magnetic poles have been moving increasingly faster towards Siberia in the last few years. These poles move because of underground streams of the molten core deep below. Could these new flows potentially heat the earth's surface and the ocean above?
