Instead of carrying the babies until they hatched, as in most species of sea spiders, one parent (likely the father) spent two days attaching the eggs to the rocky bottom where they developed for several months before hatching as tiny ...
Marine heatwaves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas emissions -- as shown in a new ...
The Arctic is changing rapidly due to climate change. It is not only affected by increasing surface temperatures, but also by warm water from the Atlantic, which is flowing in more and more -- changing the structures and functions of the ecosystem ...
A recent genetic discovery has revealed that the pale grey plumage of the tawny owl is linked to crucial functions that aid the bird's survival in cold environments. As global temperatures rise, dark ...

The massive 2015 flooding of the Sagavanirktok River in northern Alaska had immediate impacts, including closure of the Dalton Highway for several days, but it also contributed to longer-term ground ...

In a new study, researchers examined the waxy coatings of leaves preserved as organic molecules within sediment from the early-to-middle Holocene, a period of intense warming that occurred due to ...

An international team of scientists has presented research findings that reveal a crucial role of biological particles, including pollen, spores, and bacteria, in the formation of ice within Arctic ...

Past cycles of climate change, along with human exploitation, have led to only small and isolated stocks of Atlantic walrus remaining. The current population is at high risk of the same issues ...

In the 'weather kitchen,' the interplay between the Azores High and Icelandic Low has a substantial effect on how much warm water the Atlantic transports to the Arctic along the Norwegian ...

New research shows that amplified global warming in the Canadian High Arctic drove a profound shift in the structure of a river network carved into a permafrost landscape in only 60 ...

The climate-driven advance of beavers into the Arctic tundra is causing the release of more methane -- a greenhouse gas -- into the atmosphere. Beavers, as everyone knows, like to make dams. Those ...
