Subsiding landscape

In recent years thermokarst lakes have become more common in Siberia as the permafrost thaws. Characterised by uneven surfaces of marsh, pools of water and small mounds of earth left standing, once supported by ice. Recent scientific studies show that the release of methane from this type of lakes is significantly increasing.
