When geologists like James Hutton and Charles Lyall first began to read the past of our planet in fossils and in the strata of rock 200 years ago, they noticed something ominous. There were fossilized seashells on mountaintops. Mountaintops had once been at the bottom of seas. What’s more, solid land had once been swamp. And coastal real estate had been the most unstable of all, ending up underwater or high and dry. We humans are coast-hugging creatures. As Plato put it, we are like frogs dotted around a pond. Over 60% of us live near coasts. And coasts are fragile places to be.
The bottom line? Weather change will come. Massive weather change. It will come with or without the mitigation of greenhouse gases. And—like the indigenous people of Indonesia’s Aceh who build their houses on stilts–we have to be prepared to triumph over disaster. We cannot waste trillions on just one form of climate change. We have to be prepared for both fire and ice. Or, to put it differently, we have to realize that Mother Nature is not nice.
