The Arctic may seem like a frozen and desolate environment where nothing ever changes. But the climate of this unique and remote region can be both an early indicator of the climate of the rest of the Earth and a driver for weather patterns across the globe. William Chapman explains why scientists often describe the Arctic as the “canary in the coal mine” when it comes to climate change.
