As I write these words, much of North America is sweltering under near-tropical heat and humidity. Parts of the Middle East have set all-time high temperatures for the Old World, coming within a few degrees of Death Valley’s global record. The melting of the Greenland ice cap has tripled in recent years, and reports from the arctic coast of Siberia describe vast swathes of tundra bubbling with methane as the permafrost underneath them melts in 80°F weather. Far to the south, seawater pours through the streets of Miami Beach whenever a high tide coincides with an onshore wind; the slowing of the Gulf Stream, as the ocean’s deep water circulation slows to a crawl, is causing seawater to pile up off the Atlantic coast of the US, amplifying the effect of sea level rise.
All these things are harbingers of a profoundly troubled future. All of them were predicted, some in extensive detail, in the print and online literature of climate change activism over the last few decades. Not that long ago, huge protest marches and well-funded advocacy organizations demanded changes that would prevent these things from happening, and politicians mouthed slogans about stopping global warming in its tracks. Somehow, though, the marchers went off to do something else with their spare time, the advocacy organizations ended up preaching to a dwindling choir, and the politicians started using other slogans to distract the electorate.
