US EditionArctic matter pathways are poised for major shifts amidst climate change, Transpolar Drift study finds
- Polar bears are adapting to hunger by spending more time on land, which brings them closer to human settlements and increases risk, as noted by wildlife scientist Tom Smith.
- The Arctic is losing sea ice rapidly, with a decrease of about 40 percent since 1979, and has experienced ecological instability due to rising temperatures, which have risen nearly four times faster than the global average.
- Experts advocate for better waste management and the use of deterrents to reduce bear encounters, with towns like Churchill, Canada successfully reducing conflicts by closing open dumps.
- Dmitry Kokh documented nearly 20 polar bears near a deserted Soviet weather station, highlighting new behaviors that can be dangerous to communities and wildlife.

Experts issue urgent warning after witnessing unsettling shift in polar bear actions: 'We were super surprised'
A powerful photo series showing polar bears wandering through abandoned buildings on a remote Russian island has captured the world's attention — but experts say it's not just an eerie snapshot. It's a warning sign. As sea ice continues to shrink, polar bears are adapting in unexpected and troubling ways, and their growing presence on land could put both wildlife and people at risk. What's happening? Wildlife photographer Dmitry Kokh was seek…
Pioneering research reveals Arctic matter pathways poised for major shifts amidst climate change
A new study has shed unprecedented light on the highly variable and climate-sensitive routes that substances from Siberian rivers use to travel across the Arctic Ocean. The findings raise fresh concerns about the increasing spread of pollutants and the potential consequences for fragile polar ecosystems as climate change accelerates.
The time of emergence of Arctic warming, wetting and sea ice melting
In the rapidly warming and wetting Arctic, the time of emergence (ToE) of a new climate state occurs when trends of climate indicators are large enough to surpass the strong natural climate fluctuations in the Arctic. Thus far, uncertainties in climate model projections, variability and methods have yielded diverging estimates of Arctic ToE. Here we use a robust method and future projections of multiple state-of-the-art climate models to show th…
Melting Ice, Moving Pollutants: The Arctic Drift That’s Rewriting Ocean Chemistry
A groundbreaking study reveals that the Transpolar Drift, a major Arctic current, is far more dynamic than once thought. As sea ice melts and ocean patterns shift, pollutants from Siberian rivers are spreading farther and faster, posing rising threats to fragile polar ecosystems. Pollutants on the Move as Climate Warms A new study has revealed [...]
Global warming is melting Arctic ice. Can science refreeze it?
In the dim twilight of an Arctic winter’s day, with the low sun stretching its orange fingers across the frozen sea, a group of researchers drill a hole through the ice and insert a hydrogen-powered pump. It looks unremarkable — a piece of pipe protruding from a metal cylinder — but it holds many hopes for protecting this landscape. Soon, it is sucking up seawater from below and spewing it onto the surface, flooding the area with a thin layer of…
