Why the Arctic’s rivers are rusting

  New study explains what’s behind the toxic shift Scientists have identified the two biggest reasons that once-pristine rivers across the Arctic are growing cloudy with toxic orange iron particles that smother insects and suffocate fish.  A new study published in Communications Earth & Environment builds on earlier research documenting widespread contamination in Alaska’s Brooks Range. As the climate warms, a […]

Arctic Ocean food chain disrupted as key tipping point passed

  An irreversible shift in the chemical make-up of the Arctic Ocean driven by climate change is disrupting the region’s food chain, a study suggests. Widespread loss of Arctic sea ice has led to a sharp fall in levels of a key nutrient, affecting populations of plankton, fish, seabirds and marine mammals, researchers say. Their […]
