Summary

Story summary

CryoSat-2 observations identify 85 subglacial lakes beneath Antarctica, revealing a dynamic water system.
These lakes lubricate glaciers, accelerating flow toward the ocean and possibly increasing sea level rise.
Lakes under David Glacier are interconnected, and drainage events affect lakes more than 100 km away.
The results challenge the view of Antarctica as static, underscoring the need for updated climate models.
