Bill McKibben writes: The next 10 years will be decisive when it comes to the planet’s future — what we do (or don’t) will play out over geologic time.
It could, if we set our minds to it, be the decade when the planet’s use of fossil fuels peaks and then rapidly declines. We’ve built a movement that, for the moment, is starting to tie down the fossil fuel industry: from the tarsands of Alberta to the (as yet unbuilt) giant new mines of Australia’s Galilee Basin, the big players in coal, gas, and oil are bothered and even bewildered by a new strain of activist. They’re losing on the image front: when the Rockefeller family, the Church of England, and Prince Charles have begun divesting their fossil fuel stocks, you know the tide has turned.
And with it comes the sudden chance to replace that fossil fuel, fast and relatively easily. Out of nowhere the price of solar panels has fallen like an anvil from a skyscraper, dropping 75 percent in the last six years. Renewable energy is suddenly as cheap or cheaper than the bad stuff, even before you figure in the insane monetary cost of global warming. So in Bangladesh they’re solarizing 60,000 huts a month; the whole country may be panelled by 2020.
That rapid change wouldn’t be enough to stop global warming — we’re already seeing drastic changes, as anyone living through California’s drought can attest. We’ll continue to see record-breaking years (like 2014. And like 2015 so far). We’ll have to deal with record flooding. The ocean will grow more acidic. But maybe, if we really ratchet up the transition we’ll avoid a challenge of civilization-scale. [Continue reading…]
