- Geoengineers are planning to test massive underwater curtains that could slow catastrophic glacial melting.
- The Thwaites, a.k.a. "doomsday glacier," has lost over 1,000 billion tons of ice since 2000.
- If the Thwaites collapsed entirely, global sea levels would ultimately rise by about 10 feet.
A couple feet of sea level rise may not sound like a lot. But if sea levels rose by 2 feet worldwide, the effects on coastal communities would be catastrophic.
