Arctic Ocean: Climate Change Is Flooding the Remote North With Light and New Species

At just over 14 million square kilometres, the Arctic Ocean is the smallest and shallowest of the world’s oceans. It is also the coldest. An expansive raft of sea ice floats near its centre, expanding in the long, cold, dark winter, and contracting in the summer, as the Sun climbs higher in the sky.

Arctic Ocean could be ice-free for part of the year as soon as 2044

It's hard to imagine the Arctic without sea ice.But according to a new study by UCLA climate scientists, human-caused climate change is on track to make the Arctic Ocean functionally ice-free for part of each year starting sometime between 2044 and 2067.

Language is everything. Those who argue for oil drilling in the Arctic national wildlife refuge, a place of stunning wild beauty in far north-east Alaska, seldom call it what it is – a refuge.

Alaska worries for its salmon run as climate change warms Arctic waters

With marine heat waves helping to wipe out some of Alaska’s storied salmon runs in recent years, officials have resorted to sending emergency food shipments to affected communities while scientists warn that the industry’s days of traditional harvests may be numbered.

Al Roker travels to the Arctic for firsthand look at climate change

What happens in the Arctic doesn’t stay in the Arctic. And scientists studying global warming are trying to learn why.That’s why Al Roker headed to Utqiagvik, Alaska, considered ground zero for climate change, and learn from the scientists gathering critical information there that could help sav ...

Air temperatures in the Arctic are driving system change

A new paper shows that air temperature is the "smoking gun" behind climate change in the Arctic, according to John Walsh, chief scientist for the UAF International Arctic Research Center.

Africa: Big International Gathering Will Home in On Migratory Species

From whale sharks to Monarch butterflies, many animals are hardwired to migrate along set routes in search of food or a breeding area--and in some cases they've been doing this for tens of millions of years. The Arctic tern migrates the longest distances of any animal, flying over 25,000 km each ...

A human right to nature: The people suing governments for environmental damage

An Asian megacity partially locked down because of pollution. Acres of farms in Africa destroyed by extreme weather. Ancient Arctic cultures disappearing with melting ice. This isn’t the future. It’s happening now.

A groggy climate giant: subsea permafrost is still waking up after 12,000 years

In the far north, the swelling Arctic Ocean inundated vast swaths of coastal tundra and steppe ecosystems. Though the ocean water was only a few degrees above freezing, it started to thaw the permafrost beneath it, exposing billions of tons of organic matter to microbial breakdown.
