I saw this grafitti on a sidewalk in Melbourne as the Brisbane floods were raging. I’ve often looked at those signs swinging in the back windows of cars and felt that it was naive to imagine they have meaning to people in other vehicles. Yet at a time of uncertainty, desire to help, and sympathy for those who’d been hit by water that started as a trickle and rose swiftly, I loved it that someone had written graffiti on a Thornbury sidewalk drawing attention to human vulnerability. Vulnerability is a key word in climate adaptation, but sometimes starts looking like jargon.
