New Antarctic Ice Sheet Tipping Point Identified, Raising Sea Level Concerns

Warm seawater intrusion accelerates melting beneath ice sheets, potentially doubling previous sea level rise estimates.

Scientists have discovered a new tipping point for Antarctic ice sheet melting due to warm seawater seeping beneath the ice.
This process is currently not included in climate models, leading to potential underestimates of future sea level rise.
The intrusion of warm seawater creates cavities, accelerating ice melt and increasing the flow of ice into the ocean.
Even small increases in ocean temperature can significantly impact the rate of ice melting and sea level rise.
Urgent updates to climate models and increased climate action are needed to address these findings.
