Humans are in the process of changing the planet in a way that hasn’t happened in 2.6 million years.
For eons, the Laurentide Ice Sheet has been a fixture of North America. At its peak, it covered the majority of Canada and sent icy tendrils down across the Midwest and Northeast, covering Chicago, New York and Toronto in a mile or more of ice. It helped carved mountains as it advanced, and it filled the Great Lakes as it receded at the end of the last Ice Age.
About 2,000 years ago, the ice sheet remnants reached equilibrium on Baffin Island, Canada’s largest island, now dubbed the Barnes Ice Cap. But that equilibrium has been disrupted by human-driven climate change.
A new study shows that the last vestige of the once-mighty ice sheet faces near certain death, even if the world rapidly curtails its carbon pollution. The results indicate the Arctic has entered a state nearly unheard of since the Pliocene, an epoch when the Arctic was largely free of ice.
