Why the Collapse and Melting of the Thwaites Glacier Has Big Consequences

The unlocking of the Thwaites glacier threatens global sea level rise that will have consequences today, and for decades to come.


Research presented at the American Geophysical Union this month found cracks on the ice shelf holding back the Thwaites glacier: a mass of dense, landlocked ice the size of Florida. When the shelf collapses, which scientists now estimate will happen in five years, Thwaites will start moving toward the ocean, leading to sea level rise that exceeds even our worst-case scenario projections and would threaten coastal cities and communities around the world. Ethan breaks down this new research and contemplates what level of panic is appropriate in this week’s “Tip of the Iceberg.”
