The New Yorker:

The climate heated up, but clean energy did, too.

By Bill McKibben

When 2023 began, it seemed likely to be just one more year in the ongoing collapse of the world’s climate system. We were at the tail end of a long La Niña cold period in the Pacific, which meant that, although global temperatures had been near record levels for the past few years, they hadn’t quite topped 2016, the period of the last strong El Niño, which brought the hottest year to date—not to mention considerable havoc from Australia to Alaska. Amid signs of that Pacific warm current starting to build anew, climatologists looked ahead to next year as the time when all hell might break loose. Experts said it was possible that in 2024 we could go past 1.5 degrees Celsius above pre-industrial temperatures—the mark that we had pledged to try to avoid at the Paris climate summit just eight years ago.

Instead, dire things began happening much, much sooner. This spring, the keepers of various data sets pointed out that sea-surface temperatures around the globe were setting records. In July, a buoy off the Florida Keys recorded what some meteorologists believe is the highest marine temperature ever measured, setting in at 101.1 degrees, which is right about where people keep their hot tubs. That extreme heat soon moved onshore; because the northern hemisphere has more land than the southern, this is always the time of year when consolidated global temperatures reach their height. And on July 3rd scientists reported that, if you averaged in all the earth’s weather stations, ships, ocean buoys, and satellites, as an expert explained to the Washington Post, the planet had recorded the hottest day in the history of measurements. Thermometers stretch back only a few centuries, but scientists are good at assembling proxy markers from glacial cores and lake sediments; they said that this may have been one of the hottest days in at least a hundred and twenty-five thousand years, which takes us about back to the point when people began using shells as decorations. July 4th was hotter, and then July 6th broke the record again. As for the year as a whole, data from the World Meteorological Agency show that, as the U.N. Secretary-General, António Guterres, told the global climate talks in Dubai last week, we can safely say, even with weeks to go, that 2023 will take the title.
