Executive Summary
Studies link higher emissions to faster Antarctic ice loss, rising sea level, and widening long-term risks for coasts and ecosystems
- Historically calibrated projections extend Antarctic mass change estimates through 2300
- The analysis combines CMIP6 climate trajectories with two ice-sheet models
- Emissions, climate model choice and model uncertainty all shape projected sea-level contribution
- Holding 2300 climate changes through 3000 tests committed ice-sheet response
- Antarctic mass loss is expected to continue this century under all emission scenarios
- Observed sea-level rise over 30 years closely matched mid-1990s projections
- Satellite records showed ice-sheet melt contributed more sea-level rise than early models expected
Quick Facts
- What: Projected Antarctic mass loss and sea-level rise
- Where: Antarctica and vulnerable low-lying coasts
- Why: To better estimate long-term warming impacts and coastal risk
- Who: Researchers studying Antarctic ice sheets and sea level
- When: Through 2300 and in observed satellite records

Featured Article
Researchers used CMIP6 GCMs and ISMIP6-calibrated ice-sheet models in the 2020s to project Antarctic mass loss and sea-level contribution through 2300 across emission scenarios in Antarctica.

Scientists from Newcastle University and the British Antarctic Survey modeled 2100 outcomes for the Antarctic Peninsula, finding higher emissions will accelerate ocean warming, ice loss, and ecosystem collapse.
Tulane and collaborators report in 2025 that 30-year satellite altimetry confirms mid-1990s global sea-level projections while showing larger-than-expected ice-sheet melt, affecting regional risk assessments in places like south Louisiana.
