Thermokarst lakes accelerate deep permafrost thaw and the mobilization of previously frozen soil organic carbon. This leads to microbial decomposition and large releases of carbon dioxide (CO _2 ) and methane (CH _4 ) that enhance climate warming. However, the time scale of permafrost-carbon emissio...
