Ninety-three trillion dollars is a lot of money. It’s more than the entire globe’s gross domestic product.

It is also, if you ask many Republicans, how much the Green New Deal would cost over the course of a decade. Senators Ted Cruz, Mitch McConnell, and Thom Tillis have cited that number of late, as have their colleagues in the House, like rising star Dan Crenshaw. The GOP’s Twitter account can’t shut up about it, either.

The $93 trillion figure was dreamed up by a conservative think tank. To get there, the American Action Forum added $5.4 trillion for a low-carbon electricity grid, $2.7 trillion for a net-zero emissions system, and $4.2 trillion for green housing—which, fair enough. But then AAF added $36 trillion for “universal health care,” an estimate from a study by the AAF-linked Center for Health and Economy, and $45 trillion for a jobs guarantee.* More importantly, AAF refused to consider any net economic benefits from transitioning away from fossil fuels and zeroing out emissions. And why would they? As Amir Jina, an assistant professor at the University of Chicago’s Harris School of Public Policy Studies, told me, “You say any number like $93 trillion, people’s eyebrows are going to rise.”

Democrats are trying to correct this disinformation campaign. Senator Ed Markey, who introduced the Green New Deal resolution along with Congresswoman Alexandria Ocasio-Cortez, called $93 trillion “a total fabrication.” And other legislators have started talking about the costs of inaction on climate change. But the Democrats aren’t doing enough to hammer home how expensive the Republican alternative to the Green New Deal really is. Here’s how much it will cost America to do nothing about the climate crisis.

As the planet warms, we won’t just lose more beachfront property to rising seas, and more riverfront property to rising rivers. An increase in air pollution will cause a concomitant increase in hospitalizations. Bridges and roads will buckle and melt under rising temperatures. The agriculture industry will wither under more frequent, more severe droughts. Wildfires will burn hotter and longer, and further encroach on urban areas. Diseases that we didn’t formerly contend with, like Dengue fever, will spread. Ski season will shorten.
