"Across the Arctic, strange things are happening to the landscape.
Massive lakes, several square miles in size, have disappeared in the span of a
few days. Hillsides slump. Ice-rich ground collapses, leaving the landscape
wavy where it once was flat, and in some locations creating vast fields of
large, sunken polygons.
It’s evidence that permafrost, the long-frozen soil below the surface, is
thawing. That’s bad news for the communities built above it – and for the
global climate.
As an ecologist, I study these dynamic landscape interactions and have been
documenting the various ways permafrost-driven landscape change has accelerated
over time. The hidden changes underway there hold warning for the future."
