Summary
[edit]DescriptionRed Alert for rivers in Alaska (Copernicus 2024-07-05).png |
English: The Arctic is disproportionately affected by climate change, and this is most evident during Northern Hemisphere summer. In some parts of Alaska, permafrost thawing seems to foster chemical weathering of minerals, microbial reduction of soil iron, and groundwater transport of metals to streams. This results in iron and trace metal-rich sediment being leached into rivers, creating an orange discoloration, and more importantly, a hostile environment for life. This scene is a true colour Sentinel-2 image from Kanaktok Creek (a tributary of the Kobuk River) in Alaska, USA, on 1 July 2024. Typically, the discoloration affects smaller streams, but it is clearly visible on this image. |
