John Mercer (glaciologist)

John Mercer was a prominent glaciologist whose research focused on ice sheets and glaciers, particularly in Greenland and Antarctica. He studied how these massive ice formations respond to climate change and contribute to sea-level rise. Mercer’s work helped reveal that melting ice could significantly impact global tides, and he was a strong advocate for understanding environmental changes to inform policy. His insights advanced scientific knowledge of glaciology and underscored the importance of monitoring ice in the context of a warming planet.
