The "wetting" or significant melting of large, antique ice sheets—specifically the Greenland Ice Sheet and sections of the Antarctic Ice Sheet—is occurring now and is projected to accelerate rapidly within this century due to human-caused climate change.
Recent studies highlight that parts of these ice sheets are more vulnerable than previously thought:
Greenland Ice Sheet (Prudhoe Dome): A study found this ice dome melted completely about 7,000 years ago during a previous warm period. Projections indicate we could reach those same temperatures again by 2100, making a similar melting event highly likely.
Greenland General: The ice sheet is currently melting two to five times faster than before 1850. If temperatures rise by 1.7°C to 2.3°C, substantial melting is considered inevitable, with the potential for total disappearance over the next 1,000 to 10,000 years.
Antarctic Ice Sheet (West): This sector is considered very vulnerable to warming. Research shows it has previously experienced significant melt during earlier, slightly warmer periods, suggesting it could experience rapid, large-scale melting if current warming continues.
Rapid Retreat Timeline: Models suggest that under high-emission scenarios, significant portions of Antarctic and Greenland ice could experience accelerated collapse, contributing over 2 meters of sea-level rise by 2100.
Current State (2024-2025): The Antarctic Ice Sheet for the 2024–2025 season began with above-average melt extents, although some regions saw a decrease in melt by February 2025.
