In my worst post-apocalyptic imaginings, there is a place in my mind where a ravenous sea has encroached over every surface, ankle to knee to thigh to belly to throat. On a lone and desolate promontory clings one last living human who shrieks into the maelstrom a final defiance even as the pitiless rain clogs his throat: “In the church of climate alarmism, there may be no heresy more dangerous than the idea that the world will benefit from warming.”

His name is Jeff.

Not “may benefit,” mind you. “Will benefit.” The power of positive thinking meets the end of everything. And in conservative circles, many of the denials that climate disruption is really happening are now being seamlessly replaced with guarantees of coming greatness.

It gets better.

“Polar melting may cause dislocation for those who live in low-lying coastal areas, but it will also lead to safe commercial shipping in formerly inhospitable northern seas,” says Jeff Jacoby in his Boston Globe article titled, “There Are Benefits to Climate Change.”

Istanbul. San Francisco. Helsinki. Philadelphia. Dublin. New Orleans. Venice. Perth. Bangkok. Edinburgh. Honolulu. New York. Oslo. Lisbon. Los Angeles. San Diego. Hong Kong. Miami. Tokyo. Sydney. Washington. Copenhagen. Vancouver. Barcelona. Mumbai. Nagoya. Tampa. Shenzen. Guayaquil. Khulna. Palembang. Tampa. Kochi. Abidjan. Boston.

Low-lying coastal areas, all.

Cities, housing hundreds of millions of people, home to countless architectural wonders, each in itself a living history in mortar and stone and stucco and steel, wreathed in treasure and art of infinite value and absolutely, positively not waterproofed … all happy fodder before the prospect of new commercial shipping lanes.

One must ask: Shipping to whom? From where? All the places to park the ships will be underwater. When all those cities fall to the sea, there will be no commerce because civilization itself will be crumbling. In its stead, there will be starving wet survivors on the run to high ground and Jeff Jacoby’s boats happily puttering along plying their wares to people who died below the water line before the good news about climate change could properly cheer them.

“Shifts in climate are like shifts in the economy,” writes Jeff, as if he has seen such seismic shifts before. “They invariably spell good news for some and bad news for others.” According to him, all the new warm weather will keep people from freezing to death, which is a good thing.

Yet Jacoby somehow missed the explosion of diseases that will come with widespread excessive heat. He missed the massive ecological die-offs on land and in the ocean that will be caused by high heat. He missed the crop disasters that will be caused by high heat. He missed the population displacement that will make our current refugee crisis seem like a longer than usual walk in the park by comparison. And then there is the methane bomb waiting to detonate once the northern permafrost finally melts from all this fortunate heat.

“The effects of climate change,” concludes Jacoby, “range from the obvious (lower heating bills) to the subtle (more habitat for moose and endangered sharks). Territory formerly deemed too forbiddingly cold will grow more temperate — and valuable. Delicacies from lobster to blueberries may become more plentiful. Bottom line? Global warming will bring gains as well as losses, upsides no less than downsides. Climate science isn’t a good-and-evil morality tale. Climate discourse shouldn’t be either.”

There it is, folks. The bridge from climate change denial to acceptance, long deemed unpassable, has been traversed by none other than Boston’s own mini-Rush Limbaugh. Mr. Jacoby has dutifully hauled water for every bad conservative idea since the Hawley-Smoot Tariff Act, but here, he is road-testing what to do when denial and obfuscation are no longer viable tactics. It’s as if he’s deploying an evil version of the “Stages of Grief.” Last comes acceptance … but with a catch.

One can go on only so long denying the obvious before something has to give. Here, Jacoby accepts the premise that climate change is upon us, but rather than face the grim and dangerous reality of it, he chooses instead to look on the bright side. Sure, Republicans colluded with the energy industry for decades to deny the threat of climate change so their friends could get rich and now we’re all going to suffer for it, but blueberries! Heat bills! Lobster, so you can pretend to be rich!

Jacoby and other conservatives who now accept climate change have opened a window into our future. He and the people he represents will fight as hard as they can to get what they want — which is the loot, always the loot, the loot every single time — until the moment comes when they sound foolish even to themselves. When that happens, they will turn on a dime and begin talking up the advantages to be found in the disasters they have created. Jacoby shows them the way by moving from “it’s not real” to “no big deal” in one sideways shuffle, locating the financial upside — valuable new land! — and managing to sound like a scold all at once.

When the harrowing effects of the GOP tax plan begin bleeding all over Main Street, when the true nature of Donald Trump’s relationship with Russia is revealed, when the attacks on Medicare and Social Security wreak havoc on the lives of elderly Americans, when all the lies no longer have a place to hide, this will be the new gospel, preached from the promontory by the likes of Jeff and his friends.

God help us all.
