EVERY TIME SOMEONE in a position of power (for example) says that a cold snap in winter proves that climate change is not a thing, a dutiful chorus responds with a familiar refrain: Weather is not climate. Weather happens on the scale of days or weeks, over a distance relevant to cities or states. Climate happens over decades, centuries even, to an entire planet.
The question of what can make human beings understand climate change is literally an existential one. It’s complicated by humans’ pathetically short lifespan and their attention-span, roughly akin to that of a cat in a laser-pointer QA lab. How can anyone expect people to grasp the planetary, millennium-encompassing implications of their half-remembered actions? There’s bad news on that front, and as is customary with bad news, it comes from Twitter.
