The Arctic is continuing to warm at a pace far exceeding the rest of the planet, according to the Arctic Report Card 2025.

Despite falling global mercury emissions, mercury levels in Arctic wildlife continue to rise. A new study reveals that ocean currents are delivering legacy mercury pollution from distant regions like ...

For decades, scientists believed the Arctic Ocean was sealed under a massive slab of ice during the coldest ice ages — but new research proves otherwise. Sediment samples from the seafloor, paired ...

Mercury (Hg) is an environmental concern in the Arctic, where high concentrations are found in top predators such as polar bears and toothed whales. Despite declining atmospheric Hg emissions since ...

Led by the European Research Council Synergy Grant project Into the Blue – i2B, the research team studied sediment cores collected from the seafloor of the central Nordic Seas and Yermak Plateau, ...

The Arctic Ocean, once locked in a vault of thick, old ice, now is transforming at lightspeed. Temperatures there are increasing at up to four times the rate of the planet overall, melting sea ice ...

In the coming decades, climate change is likely to lead to a loss of sea ice in and an influx of warmer water to the Arctic Ocean, affecting the ocean's vertical circulation. Brown and colleagues ...
