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.
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.

Arctic sea ice algae contaminated with microplastics have serious consequences for ecosystems and the climate.
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.
Russia is attempting to claim more of the Arctic seabed, an area rich in oil, gas and minerals. It’s also expanding shipping and reopening Arctic bases. Here are two things the U.S. can do about it.

A transcript of episode 5 of The Conversation Weekly podcast, including stories on the Arctic Ocean and new archaeological finds in Tanzania’s Olduvai Gorge.
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.
Belugas use sound to communicate, navigate the dark marine environment and find food. But climate change is opening up Arctic waters to more sound, and could affect the health and survival of belugas.
More than 600 experts will spend the next year drifting in Arctic waters to gain a better understanding of how climate change is affecting the region and how it can be fought.
