New NASA-funded research has discovered that Arctic permafrost’s expected gradual thawing and the associated release of greenhouse gases to the atmosphere may actually be sped up by instances of a relatively little known process called abrupt thawing. Abrupt thawing takes place under a certain type of Arctic lake, known as a thermokarst lake that forms […]
Plants and soil in the Arctic tundra absorb and store mercury released into the atmosphere by industry and mining in the Earth’s temperate regions, leading to soil mercury levels five times higher than in lower latitudes, according to a new study by researchers supported by the National Science Foundation (NSF). The research was published this […]
