‘Abrupt thaw’ of permafrost beneath lakes could significantly affect climate change models

Methane released by thawing permafrost from some Arctic lakes could significantly accelerate climate change, according to a new study. Unlike shallow, gradual thawing of terrestrial permafrost, the abrupt thaw beneath thermokarst lakes is irreversible this century. Even climate models that project only moderate warming this century will have to factor in their emissions, according to the researchers.
