## Thwaites Glacier Melting
The world’s largest glacier is melting much faster than previously expected, potentially adding twice as much to global sea levels over the next century.
## Warm Seawater Impact
New research shows warm seawater is pushing underneath the Thwaites glacier, melting its core and accelerating mass loss.
## Sea Level Consequence
This melting could add 1.2 inches (30mm) to water levels even if global warming does not accelerate as predicted.
## Key takeaway

Thwaites glacier in West Antarctica is melting faster than previously thought, potentially adding 1.2 inches (30mm) to global sea levels by 2100.
