Your Weather Tweets Are Showing Your Climate Amnesia

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 problem is, guess what timescale and space-scale people live on? The question of what can make human beings understand climate change is literally an existential one.
