‘Imminent’ tipping point threatening Europe’s permafrost peatlands

Large swathes of northern Europe and western Siberia may become “climatically unsuitable” for carbon-rich permafrost peatlands within a few decades, even under moderate warming scenarios, a new study warns. These carbon-rich landscapes span more than 1.
