Climate change is causing not only permafrost loss in Alaska but also changing the freshwater chemistry and hydrology of Alaska's Yukon River Basin. These changes could have a profound impact on global climate, as revealed in a study published in Geophysical Research Letters.
A new study suggests that the permafrost below shallow arctic lake are thawing due to the changing winter climate.
Melting Arctic ice means natural underground permafrost freezers can no longer keep food cold enough and encourages polar bears to visit inland communities for longer periods of time. This calls for new and improved above ground polar bear-resistant food storage containers.
Years after the infamous Anaktuvuk River fire – the largest recorded Arctic tundra fire – researchers have found a link between wildfires in the Arctic tundra and widespread permafrost thaw.
Researchers from University of Cambridge and University of Colorado say that if active steps are taken by nations to decrease emissions from permafrost thaw in particular, this could reduce predicted emissions cost by $37 trillion. But that's not the case yet.
It's no secret that our warming climate is causing ice everywhere to melt, but now new research shows that this thaw may release a massive storehouse of carbon in long-frozen Arctic soils.
