Arctic rivers face big changes with a warming climate, permafrost thaw and an accelerating water cycle − the effects will have global consequences

A new study shows how thawing permafrost and intensifying storms will change how water moves into and through Arctic rivers.

Arctic Report Card 2023: From wildfires to melting sea ice, the warmest summer on record had cascading impacts across the Arctic

The early heat melted snow and warmed rivers, heating up the land and downstream ocean areas. The effects harmed salmon fisheries, melted sea ice and fueled widespread fires.

The melting Arctic is a crime scene. The microbes I study have long warned us of this catastrophe – but they are also driving it

To fully understand the extent of climate-related dangers the Arctic – and our planet – is facing, we must focus on organisms too small to be seen with the naked eye.

Analyzing the fat of killer whales reveals what they eat

By analyzing small samples of killer whale fat, scientists can learn about the diets of different killer whale populations. This has implications for our understanding of changing ecosystems.
Scientists have found widespread evidence of microplastics in the Arctic Ocean. This could further stress the fragile Arctic ecosystem and the food it provides to people living there. (Shutterstock)

They’re everywhere: New study finds polyester fibres throughout the Arctic Ocean

Microplastic pollution is a global issue, but where do they come from and how are they transported across the ocean? A new study finds polyester microfibres are common throughout the Arctic Ocean.
