‘Counterintuitive finding suggests that unexpected factors may govern a glacier’s response to climate change’

From the University at Buffalo, new evidence that large ice sheets can grow/disappear quickly on decadal scales in response to regional temperature changes. A descriptive video follows. How fast can ice sheets respond to climate change? Scientists report that prehistoric … Continue reading
