This first of its kind research estimates potential releases of mercury from thawing permafrost in high and low emissions scenarios.
The researchers predicts that by 2200, the mercury emitted into the atmosphere annually by thawing permafrost could compare with current global anthropogenic emissions under a high emissions scenario. Their results were published on September 16 in Nature Communications.
“If we can hit the Paris Accord target, we expect minimal impacts to mercury concentrations in fish and water. If we continue with unconstrained emissions, however, it is likely that we will see large increases in mercury concentrations,” said Schaefer.
