NASHVILLE — I was writing a love letter to autumn and its perfect miracle of timing — the way berries ripen just as songbirds migrate through berry-filled forests — when the songbirds suddenly began to die. With no warning at all, thousands and thousands of birds, possibly millions of birds, were simply falling out of the sky.
It’s not yet clear why the birds were dying — smoke from the wildfires on the West Coast? an unseasonable cold snap? the prolonged drought? — but whatever its immediate reason, the die-off was almost certainly related to climate change or some other human-wrought hazard. Every possible explanation for the birds’ deaths leads back to our own choices.
We think of songbirds as indicator species — so sensitive to environmental disruptions that they serve as an early warning of trouble. But the fact that the environment has become increasingly inhospitable to songbirds — and to human beings — is only one measure of a planet under life-threatening stress.
The earth is getting measurably hotter, each year breaking records set the year before, while Arctic sea ice continues to thin. Wildfires are growing hotter, more frequent, more widespread and more deadly. Northeastern forests are sick. Our oceans are full of plastic. The world’s largest wetland is on fire, and the Amazon rainforest is on its way to becoming a savanna. The pandemic that has paralyzed global life is itself the manifestation of a disordered relationship between human beings and the natural world.
None of this is new. We’ve seen it all happening, worsening with every passing year, for decades now. Any chance of reversing climate change is long since gone, and the climate will inevitably continue to warm. The question now is only how much it will warm, how terrible we will let it become.
