Thwaites Glacier in West Antarctica is melting faster than expected, potentially doubling the projected sea-level rise by 2100.

The new ice sheet model developed by researchers from UC Irvine and NASA’s Jet Propulsion Laboratory reveals that Thwaites could contribute up to 30 millimeters of sea level rise without additional climate warming. This stark increase in projections underscores the glacier's instability and its significant impact on global coastlines, even under current climate conditions.

The melting will add about an inch to global sea levels by the end of this century, which is twice as much as previously thought.

This rapid melt rate signals long-term vulnerability for coastal communities worldwide. The increased water levels could exacerbate flooding and erosion, threatening infrastructure and habitats far into the future.

What is the long-term climate outlook for this region?

The accelerated melting of Thwaites Glacier suggests a more urgent need for coastal adaptation measures. Communities must prepare for higher sea levels that could displace populations and damage property. The long-term outlook indicates rising risks to both human settlements and natural ecosystems.

Preparation is critical as the threat intensifies.
