Scientists admit they are imperfect, but lying politicians cannot be trusted

It is later than you think.

The men in white coats who measure the fever of this planet have just done something remarkable.

They have taken their most terrifying prophecy—the one where your grandchildren bake beneath a sky gone mad with heat—and they have quietly laid it in a drawer. They have called it “implausible.” They have decided not to speak of it anymore.

And now the politicians, the ones who have spent thirty or forty years pretending the house was not on fire, are dancing on the grave of that prophecy like drunkards at an Irish wake.

Let us be clear about what has happened, because nobody else will be.

For the better part of a decade, scientists have kept on their books a scenario called RCP 8.5. This was the worst case.

This was the path where humanity looked at the thermometer and said, “More coal, please.”

This was seven, eight, nine degrees of warming by the time today’s babies collect Social Security. Coastlines swallowed. Crops failed. Cities uninhabitable.

The whole ugly carnival of suffering that the polite people on television call “climate impacts.”

And now that scenario is dead. The U.N.’s climate panel has pronounced it. The world did not double down on fossil fuels the way the worst-case models assumed. Renewable energy got cheap. Coal got expensive. The doomsday machine stalled out before it reached top speed.

This is good news. Let that be said plainly.

This is actual, honest-to-God good news, and there is so little of it in this world that a person might be forgiven for not recognizing it.

But here is where the story turns sour as a barrel of spoiled pickles.

The political establishment—and you know the ones, the same cheerful fellows who have been telling you for decades that climate science is a hoax, a conspiracy, a Chinese plot, or whatever fresh nonsense the think tanks are printing this week—has seized on this development like a starving dog on a pork chop.

The current occupant of the White House, a man whose relationship with truth could charitably be described as “casual,” has declared that the scientists admitted they were “WRONG! WRONG! WRONG!” His allies are saying the threat has passed. The problem is solved. Go back to your SUVs. Nothing to see here.

And this, friends, is where the betrayal lives.

Because the scenario they are now retiring was never the only disaster on the menu. It was the worst disaster. The catastrophe of catastrophes. But the second-worst scenario? The one where the world makes some progress but not nearly enough? The one where warming settles around three degrees Celsius instead of four or five?

That scenario is still devastating.

Let those words sit in your mouth for a moment. Three degrees. Five point four degrees Fahrenheit. That is not a number on a spreadsheet. That is the difference between a bad summer and a summer that kills ten thousand people. That is the difference between a drought that hurts farmers and a drought that empties entire regions. That is the difference between sea levels that annoy coastal homeowners and sea levels that erase island nations from the map.

The scientists who retired the worst-case scenario have been at pains to say this. They have written it in journals. They have posted it online. They have said, in the careful, measured language of their profession, that the next-worst scenario is still plenty bad enough to ruin your grandchildren’s lives.

But nobody is listening. Because the politicians have found a better story. The story where the scientists were fearmongers. The story where climate change was never that serious. The story where you can go back to sleep and stop worrying your head about all this unpleasantness.

And here is the cruelest part. The scientists did not lie to you. They built models. The models had a range. The worst end of that range has not come to pass, thanks in part to the very technologies those same scientists have been begging the world to adopt for thirty years. That is not a failure of science. That is a victory for human action. That is proof that when we do things right, the future bends toward the livable.

But the political establishment has no interest in that nuance. They want victory laps and headlines. They want to tell you the fire is out while the second floor is still burning.

So here we are. The truth has been stood in a corner and told to be quiet. The worst case is dead. Long live the second worst case. And the politicians are already writing the obituary for the whole problem.

Do not let them.

The scientists were not crying wolf. They were crying wolf, bear, flood, fire, and famine. They have stopped crying about the worst wolf. That does not mean the bear is not at the door.
