As sea temperatures warm in the Arctic, polar whales will likely move northward, raising questions about their ability to persist as colder habitats disappear. “We’re learning they actually give a good picture of how the …
To understand how Arctic species might respond to climate change, researchers dug into how cold-adapted species responded between previous ice ages. Biologists had concluded that as massive ice sheets retreated, temperate species began to take …
Arctic sea ice fell to its 10th lowest on record last winter, according to NASA’s National Snow and Ice Data Center. The sea ice peaked at 5.75 million square miles on Feb. 25—a tied for …
As climate change causes sea ice to recede in the Arctic, polar bears must decide whether to travel farther for their ringed seal prey or swim to land in search of whatever other prey they …
Conservation and management of populations of large herbivores like caribou and muskoxen on the Arctic tundra could help maintain rare plant species under climate change. Although it sounds strange, most species of vegetation are actually …
An interdisciplinary team of scientists and Indigenous people are working together to study how climate change and human development are impacting declining caribou herds in Canada and Alaska. The team, including caribou researchers, vegetation ecologists, …
As the climate changes, researchers want to better understand how Arctic seabirds migrate to aid conservation efforts. Using telemetry, they found three jaeger species leave a shared nesting location in the Canadian high Arctic and …
Beavers are heading northward, and they’re having a significant impact on the landscape in northern Canada and Alaska. That’s one of the findings highlighted in the Arctic Report Card 2021, published by the National Oceanic …
Climate change could change the number and location of fish that seals prey on in Hudson Bay by the end of the century, likely affecting seal populations. Past studies have shown the direct effects climate …
Traditional models predict Arctic sea ice levels well over a few weeks, but long-range forecasting is a challenge. But researchers say a new tool using artificial intelligence may be far more accurate—and much faster. IceNET …
