The Most Important Thing That Happened This Year Was the Heat

The world—its politics, its economy, and its journalism—has trouble coping with the scale of the climate crisis. We can’t quite wrap our collective head around it, which has never been clearer to me than in these waning days of 2023.

Because the most important thing that happened this year was the heat. By far. It was hotter than it has been in at least 125,000 years on this planet. Every month since May was the hottest ever recorded. Ocean temperatures set a new all-time mark, over 100°F. Canada burned, filling the air above our cities with smoke.

And yet you really wouldn’t know it from reading the wrap-ups of the year’s news now appearing on one website after another.

We’re programmed—by evolution, doubtless, and in the case of journalism by counting clicks—to look for novelty and for conflict. Climate change seems inexorable, which is the opposite of how we think about news.

Earlier today, for instance, The New York Times published an essay by investment banker and Obama consigliere Steven Rattner on “ten charts that mattered in 2023.” That’s the most establishment voice imaginable, in the most establishment spot. And the global temperature curve did make the list—at #10, well behind graphs about the fall in inflation, the president’s approval levels, the number of Trump indictments, the surge in immigrants, and the speed with with the GOP defenestrated Kevin McCarthy.

Indeed, yesterday the Times and The Washington Post both published fine stories about 2023’s record temperatures, but they were odd: In each case, they centered on whether the year was enough to show that the climate crisis was “accelerating.” It’s an interesting question, drawing mainly on a powerful new paper by James Hansen (one that readers of this newsletter found out about last winter), but the premise of the reporting, if you take a step back, is kind of wild. Because the climate crisis is already crashing down on us. It doesn’t require “acceleration” to be the biggest—by orders of magnitude—dilemma facing our species.

In a sense, though, that’s the problem. Those stories in the Times and Post were a way to search for a new angle to a story that doesn’t change quite fast enough to count as news. (In geological terms, we’re warming at hellish pace; but that’s not how the 24/7 news cycle works.) It’s been record-global-hot every day for months now: The first few of those days got some coverage, but at a certain point editors, and then readers, begin to tune out. We’re programmed—by evolution, doubtless, and in the case of journalism by counting clicks—to look for novelty and for conflict. Climate change seems inexorable, which is the opposite of how we think about news.

The war in Gaza, by contrast, fits our definitions perfectly. It is an extraordinary tragedy, it changes day by day, and it is the definition of conflict. And perhaps there’s something we can do about it (which is why many of us have been trying to build support for a cease-fire). So, rightly, it commands our attention. But in a sense, it is the very familiarity of the war that makes it easy for us to focus on it; “Mideast conflict,” like “inflation” or “presidential elections,” is an easily-accessed template in our minds. The images of the horror make us, as they should, feel uncomfortable—but it’s a familiar discomfort. The despair, and the resolve, we feel are familiar too; even the subparts of the story fit into familiar grooves (a New York Times reader would be forgiven for thinking the main front of the war is being played out in Harvard Yard, between free speech advocates and cancel culture warriors). Next year seems likely to be another orgy of familiarity: Joe Biden and Donald Trump, yet again.

Climate change has its own familiar grooves—above all the fight with the fossil fuel industry, which played out again at COP28 in Dubai. But so much of the story is actually brand new: As this year showed, we’re literally in uncharted territory, dealing with temperatures no human society has ever dealt with before. And to head off the worst, we are going to require an industrial transition on a scale we’ve never seen before: There were signs this year that that transition has begun (by midsummer we were installing a gigawatt worth of solar panels a day), but it will have to go much much faster.

These changes—the physical ones, and the political and economic ones—are almost inconceivable to us. That’s my point; they don’t fit our easy templates.

And the point of my newsletter, now and in the years to come, is to try and explain the speed of our crisis, and explain what it dictates about the speed of our response. It’s a story I’ve been trying to put into perspective for 35 years now (The End of Nature was published in 1989, the first book about this crisis), and I’ll keep looking for new ways in. As the climate scientist Andrew Dessler put it in one year-end account, "The only really important question is, 'How many more years like this we have to have before the reality of how bad climate change is breaks into the public's consciousness?'"

Thank you for being part of this ongoing effort to break into that consciouness, and—well, happy new year. It’s coming at us, we might as well make it count.
