I think climate change deniers will eventually be defeated by challenges to our common lives that most of us don’t currently recognize.
As Paul Krugman has recently noted, one of those is sewage.
How many people do you know whose homes aren’t connected to a sewer line? Sewers and garbage pickup are among those (largely urban) amenities that folks fulminating about “socialism” rarely consider, but they are part and parcel of important collective public health measures.
They are also services that are rarer in some parts of the country than in others.
As Krugman reminds us, many American homes, especially in the Southeast, aren’t connected to sewer lines. They have septic tanks, and these days, more and more septic tanks are overflowing. As he notes, that’s both disgusting and a threat to public health.
The cause? Climate change. Along the Gulf and South Atlantic coasts, The Washington Post reported last week, “sea levels have risen at least six inches since 2010.” This may not sound like much, but it leads to rising groundwater and elevated risks of overflowing tanks.
The emerging sewage crisis is only one of many disasters we can expect as the planet continues to warm, and nowhere near the top of the list. But it seems to me to offer an especially graphic illustration of two points. First, the damage from climate change is likely to be more severe than even pessimists have tended to believe. Second, mitigation and adjustment — which are going to be necessary, because we’d still be headed for major effects of climate change even if we took immediate action to greatly reduce greenhouse gas emissions — will probably be far more difficult, as a political matter, than it should be.
At this point in my initial reading of the linked column, I rolled my eyes–because these days, anything and everything is more difficult as a political matter than it should be. When a significant percentage of the population insists on denying science, scholarship, logic, fact–opting to discount what their own “lying eyes” are trying to tell them–political gridlock is inevitable.
As Krugman points out,
Estimating the costs of climate change and, relatedly, the costs polluters impose every time they emit another ton of carbon dioxide requires fusing results from two disciplines. On one side, we need physical scientists to figure out how much greenhouse gas emissions will warm the planet, how this will change weather patterns and so on. On the other, we need economists to estimate how these physical changes will affect productivity, health care costs and more.
Actually, there’s a third dimension: social and geopolitical risk. How, for example, will we deal with millions or tens of millions of climate refugees? But I don’t think anyone knows how to quantify those risks.
Krugman, of course, is an economist, and he worries that the efforts so far to estimate economic costs of climate change have failed to take things like septic tank failures into account.
So what are we going to do about it? Even if we were to take drastic steps to reduce emissions right now, many of the consequences of past emissions, including much bigger increases in sea level than we’ve seen so far, are already, as it were, baked in. So we’re going to have to take a wide range of steps to mitigate the damage — including expanding sewer systems to limit the rising tide of, um, sludge.
But will we take those steps? Climate denial was originally all about fossil fuel interests, and to some extent it still is. But it has also become a front in the culture war, with politicians like Ron DeSantis of Florida — who happens to be the governor of one of the states at greatest immediate risk — apparently deciding that even mentioning climate change is woke.
Evidently, DeSantis’ definition of “woke” is “rational and informed.” Logic tell us that refusing to mention climate change–or the existence of gay people–won’t make either one disappear.
What will the politicians pandering to the frightened and angry folks frantic to reject any evidence of things they dislike or can’t understand–politicians like Indiana’s Jim Banks, who insists that climate change is a “hoax”– say when their constituents’ septic tanks fail? What will DeSantis say when significant portions of Florida are underwater. (I wonder who he’s blaming now for the rapidly growing inability of Florida residents to get property insurance–gay people??)
The disappearance of homeowners’ insurance and the failure of septic tanks are just two of the largely unanticipated–and logically inevitable– consequences of climate change. There will be others, no matter how many culture warriors like Jim Banks stand athwart reality yelling “hoax.”
