There have undoubtedly been stable periods in human history, but you and your parents, grandparents, and great-grandparents never lived through one, and neither will any children or grandchildren you may have or come to have. Everything has been changing continuously, profoundly — from the role of women to the nature of agriculture. For the past couple of hundred years, change has been accelerating in both magnificent and nightmarish ways.
Yet when we argue for change, notably changing our ways in response to climate change, we’re arguing against people who claim we’re disrupting a stable system. They insist that we’re rocking the boat unnecessarily.
I say: rock that boat. It’s a lifeboat; maybe the people in it will wake up and start rowing. Those who think they’re hanging onto a stable order are actually clinging to the wreckage of the old order, a ship already sinking, that we need to leave behind.
As you probably know, the actual oceans are rising — almost eight inches since 1880, and that’s only going to accelerate. They’re also acidifying, because they’re absorbing significant amounts of the carbon we continue to pump into the atmosphere at record levels. The ice that covers the polar seas is shrinking, while the ice shields that cover Antarctica and Greenland are melting. The water locked up in all the polar ice, as it’s unlocked by heat, is going to raise sea levels staggeringly, possibly by as much as 200 feet at some point in the future, how distant we do not know. In the temperate latitudes, warming seas breed fiercer hurricanes.
The oceans are changing fast, and for the worse. Fish stocks are dying off, as are shellfish. In many acidified oceanic regions, their shells are actuallydissolving or failing to form, which is one of the scariest, most nightmarish things I’ve ever heard. So don’t tell me that we’re rocking a stable boat on calm seas. The glorious 10,000-year period of stable climate in which humanity flourished and then exploded to overrun the Earth and all its ecosystems is over.
