A new study published in Nature<\/i> shows that some Arctic lakes sequester more greenhouse gases than they release, according to a release from the National Science Foundation.<\/p>\n
Previous research suggested that thawing Arctic permafrost, a process that leads to the creation of ephemeral thermokarst lakes, speeds atmospheric warming at a uniform rate. The new study, funded by the National Science Foundation, indicates that organically rich sediments, mosses and other plants in certain thawed lakes help absorb high levels of carbon.<\/p>\n
The researchers used previously published data, field observations, radiocarbon dating and modeling to determine that Arctic lakes have actually exhibited a net cooling effect on the atmosphere for the last 5,000 years, when examined on a millennial scale.<\/p>\n
