Ponds in the High Arctic as an unrecognized source of carbon emission

With the warming of our planet, organic carbon that is dissolved in the High Arctic permafrost is being released into ponds. The organic carbon is essentially dead organic material that becomes dissolved in lakes and oceans, but can also be found in soil. Once released from the melting permafrost, it can be biodegraded by microorganisms, in ponds more than in rivers, and emitted into the atmosphere. This might form a previously unrecognised source of carbon emission that could accelerate global warming even further.
