Special Global Warming Issue
Arctic meltdown, cleaner green energy, solving a bird mystery, and more reports from the front lines.
The amount of carbon locked up in the Arctic’s permafrost dwarfs the total that humans have released into the atmosphere. Could the wholesale melting of the Arctic trigger a series of catastrophes?

A tragic accident could have ended a project to study rosy-finches. But these young birders persevered, helping scientists understand how global warming affects these little-known birds and other species, too.
Balance of Power
Even green-energy development has a carbon footprint. But in Wyoming’s windswept sagebrush steppe, goodwill and a novel collaboration have produced a solution to suit all—including the sage-grouse.
As the Florida torreya hangs on by a thread in its dwindling range, activists are taking matters into their own determined hands. Is “assisted migration” a valid conservation option in a world being transformed by climate change, or is this activism gone too far?
