Fighting climate change is not going to cost you anything
We can have solar panels and butter
The entire political debate about climate change is backwards.
The traditional narrative goes something like this: Fighting climate change is going to cost a ton of money. Therefore any policy program must be rigorously analyzed to figure out if it is the most efficient option. That is the background assumption of the so-called "lukewarmers," who make outrageously dishonest cases for basically ignoring climate change because it will cost too much, but also for the cadre of economists designing revenue-neutral carbon taxes so as to maximize efficiency.
Not only is this picture false, climate policy would have the precise opposite effect. A ferociously aggressive program of climate investment would drastically increase overall economic production, and be beneficial on net for nearly every American. Conversely, failing to act on climate change would almost certainly cause spectacular economic devastation.

Now, of course it's true that climate policy would require a whole lot of direct spending. We need to build out hundreds of billions of dollars in renewable energy and storage, modernize the electrical grid, accelerate the development and deployment of electric vehicles, make heating and cooling drastically more efficient, construct national passenger rail, and on and on. More or less the entire economy needs to be overhauled.
In a country that was roaring along at full employment and maximum production, that would indeed be an expensive program. But the key fact about the United States (and virtually every other wealthy nation) is that we are not at full economic capacity, and haven't been since 2007 — and that means a big spending program could restore full production. Idle capacity would be brought back online, and capacity that has decayed — as long-term unemployed workers have lost skills, and businesses have shut down or foregone improvements — could be restored by pressing hard on demand. With a labor shortage, idle workers could be retrained, and plants and equipment could be updated. As economist J.W. Mason has calculated, we are something like $3 trillion (or more than the entire GDP of California) below the 1945-2007 output trend. A crash program of investment might not make up that entire gap, but even two-thirds of the way would be an explosion of prosperity for average people.
In another fascinating post, Mason cites evidence from the Second World War, the most relevant historical example of this logic. In 1939, the economy was badly depressed, but was stoked up to red-hot levels with war spending. Remarkably, a gigantic increase in war spending barely infringed on the consumer economy at all. Instead, almost all the war production came on top of the existing consumer economy:
Civilian production did decline a bit — mainly because various war-critical industries like steel, aluminum, oil, and rubber were reserved almost entirely for the military. But it was only about 4 percent in total. And while there were various rationing programs during the war, this was mostly to suppress inflation that would have resulted from the huge rise in incomes: From 1940-44, total civilian wages and salaries increased by 170 percent.
What's more, a crash climate investment program would be almost entirely spent inside the country. Instead of spending tons of resources on ships, tanks, and airplanes that then get sunk or blown up, green investment would be in internal improvements that provide long-term usefulness for the citizenry.
Of course, certain industries — coal, oil, and gas above all — would have to be extirpated, while other (like automobiles) would have to be totally overhauled. Taxes on the rich would have to go up considerably. But even if the climate program does infringe on the rest of the economy, the diversions will still be on behalf of almost all Americans.
That brings me to the climate scenario that actually would be incredibly costly — namely, doing nothing. That is partly the subject of a paper by Armon Rezai, Lance Taylor, and Duncan Foley at the Schwartz Center for Economic Policy Analysis. They present a sophisticated model examining how climate change might affect the world's economic future. After a lot of complicated math, they predict that unchecked climate change would more or less wreck everything. In a "business-as-usual" trajectory:
Here's what that looks like in chart form. The red dotted line is business as usual, while the black line is a moderate program to stabilize warming at 2 degrees Celsius, and the dotted teal line is an aggressive effort to stop at 1.3 degrees:

So about 62 percent of the currently-working population would be unemployed, and the world economy would lose two entire centuries of growth. But on the other hand, if warming can be headed off, then growth can continue trundling along.
Of course, as I've written before, economic prognostications are inherently very uncertain. The takeaway here should be that — contrary to glib neoliberal assumptions of infinite growth no matter what — it is easily possible to write down a credible economic model in which unchecked climate change leads to devastating economic collapse. And given the extreme costs of Hurricanes Harvey and Maria, with warming at only 1 degree Celsius, it's not at all hard to believe.
So if we are to put on our accounting hats, and think about what's the best for the American pocketbook, the answer is clear: Stop global warming, as fast as possible.
