“So McKibben does the arithmetic. To remain under the 2-degree threshold, we need to emit no more than 565 gigatons of carbon dioxide over the next 40 years. As he puts it, “It’s like saying if you want to keep your blood alcohol level legal for driving, you can’t drink more than eight beers in the next six hours.” But here is the problem. Analysts have calculated that all the claimed reserves from fossil fuel—coal, oil, and natural gas—companies add up to 2,795 gigatons, five times more than the maximum allowable, even in a scenario that itself is fraught with climate danger.
“Here’s another way of saying it: We need to leave at least 80 percent of that coal and gas and oil underground,” McKibben writes. “The problem is, extracting and burning that coal and oil and gas is already factored into the share prices of the companies involved—the value of that carbon is already counted as part of the economy.” This would be the equivalent of these companies writing off $20 trillion.
For those of us who take climate science seriously, I think that we’re left with an inescapable conclusion: It’s not enough to teach about fossil fuels, we have to teach against fossil fuels. Any curriculum discussion that fails to address the threat posed by fossil fuel consumption to humanity and the future of all life on earth is profoundly irresponsible.”
