There are enormous amounts of hydrocarbons beneath the Artic Ocean and the world has known that for many decades. If those resources could be extracted without extreme complication and expense the world would have done so before now. It makes me wonder whether the "normal state" of the Arctic is in fact lush and tropical and what we are witnessing is its return to that state, albeit accelerated by humankind's increasing presence and its invention of industrial processes that use those hydrocarbons. Given the exploration that has already taken place over the past decades, one would assume there are core samples, or core sample data, located somewhere that indicate the true nature of the changes the Arctic Ocean has experienced and continues to express.
