Science Highlights

Results show that climate warming and permafrost thaw could potentially enhance methylmercury toxin production by an order of magnitude, impacting Arctic terrestrial and aquatic ecosystems by increased exposure to mercury through bioaccumulation and biomagnification in the food web.

Ice wedges, which are a common subsurface feature in permafrost landscapes, appear to be rapidly melting throughout the Arctic altering the microtopography and causing succession in polygon type that has profound changes to the storage and flow of water on the landscape
