Global warming moved from the North Pole to your backyard — and so did its symbols. Starting about two decades ago, National Geographic and the like began churning out images of lonely, hungry bears adrift on melting ice floes, painting them as the hapless victims of climate change. But today, that symbol has largely fallen out of fashion. The advocacy group ClimateXChange even says the focus on the polar bear has done a “disservice” to the goals of the movement, and a handbook for public engagement for members of the Intergovernmental Panel on Climate Change, the world’s leading group of climate experts convened by the United Nations, says the image prompts “cynicism and fatigue.” As climate change began to have visible effects in richer countries, the movement to new imagery happened naturally.
