Wanless, who has for some time been predicting ice melting rates and resulting sea level rises that are far in excess of what the Intergovernmental Panel on Climate Change (IPCC) has been predicting -- as much as 10 feet by 2050 and 15 or 20 feet by the end of this century, vs. just three feet for the IPCC -- says, "Scientists tend to be pretty conservative. We don't like to scare people, and we don't like to step out of our little predictable boxes. But I suspect the situation is going to spin out of hand pretty quickly." He says, "If you look at the history of warming periods, things can move pretty fast, and when that happens that's when you get extinction events."
He adds, "I would not discount the possibility that it could happen in the next ten years."
Making matters worse, Wanless adds, is the fact that a large enough methane eruption in the arctic, besides contributing to accelerated global warming, could also lead to a significant reduction of the amount of oxygen in the atmosphere (currently about 21%). This is because methane in the atmosphere breaks down fairly quickly, over the course of a decade or so, into water vapor and CO2, but in doing do, it requires oxygen atoms, which it would pull out of the atmosphere. That reduction in oxygen would lead to reduced viability and growth rates of plants and animals, as well as to a significant reduction in crop productivity. This dire trend would be enhanced by a second threat to atmospheric oxygen, which is the oxygen-producing plankton in the ocean. If sea temperatures rise much, and increased acidification of the ocean continues apace as the oceans absorb more CO2, plankton, the earth's main producers of new oxygen, could shut down that source of new free oxygen.
So there you have it my fellow humans: it's at least possible that we could be looking at an epic extinction event, caused by ourselves, which could include exterminating our own species, or at least what we call "civilization," in as little as nine years.
What is particularly galling, in thinking about this, is the prospect that eight of those last years might find us living in a country led by Donald Trump, a climate-change denier who seems hell-bent on promoting measures, like extracting more oil from the Canadian tar sands, the North Dakota Bakkan shale fields and the Arctic sea floor, as well as re-opening coal mines, that will just make such a dystopian future even more likely than it already is.
The only "bright side" to this picture is that it may not matter that much what Trump does, because we've already, during the last eight Obama years and the last eight Bush years before that, dithered away so much time that the carbon already in the atmosphere -- about 405 ppm -- has long since passed the 380 ppm level at which, during the last warming period of the earth, sea levels were 100 feet higher than they are today.
That is to say, we're already past the point of no return and it's just the lag being caused by the time it takes for ice sheets to melt and for the huge ocean heat sinks to warm in response to the higher carbon levels in the atmosphere that is saving us from facing this disaster right now.
It is at this stage of the game either too late to stop, or we should be embarking on a global crash program to reduce carbon emissions the likes of which humanity has never known or contemplated.
Hard to imagine that happening though, particularly here in a country where half the people don't even think climate change is happening, or if they do notice things getting warmer, think that's just a peachy thing that will reduce their heating bills.
