Melting Ice and Heavier Snowfall: An Antarctic Paradox
New research reveals an interesting phenomenon in Antarctica – declining sea ice is linked to increased regional snowfall. While this can temporarily slow global sea level rise, it is unlikely to fully offset long-term ice melt impacts.
Sea Ice Loss Boosts Snowfall
A study in Geophysical Research Letters found less sea ice near the Amundsen Sea causes more evaporation and precipitation. Lead author Jessica Kromer explained while more snowfall counteracts some melting, it is not enough to negate climate change effects.
Why Sea Ice Matters
Understanding snowfall rates is key when tracking the ice sheet’s role in sea level changes. Sea ice modulates regional evaporation. Its loss amplifies the process, bringing heavier snowfall.
An Intensifying Feedback Loop
The authors concluded that as the planet warms and Antarctic sea ice decline accelerates, evaporation and associated snowfall will also intensify. This paradoxical effect can temporarily counteract but not prevent long-term sea level rise.
