As the Arctic Warms, AI Forecasts Scope Out Shifting Sea Ice

While AI also requires complex data and a lot of initial computing power, once an algorithm is trained on the right amount and kind of data, it can detect patterns in climate conditions more quickly than physics-based models, according to Thomas Anderson, a data scientist at the British Antarctic Survey who developed an AI ice forecast called IceNet.

More Lightning in the Arctic Is Bad News for the Planet

“The 2020 heat wave in the Russian Arctic shows how—even at high latitudes—really warm weather conditions can develop that can lead to fires that burn intensely and can grow to be very large,” says Isla Myers-Smith, an ecologist at the University of Edinburgh who studies the region but wasn’t involved in this new work.

Narwhal Tusks Tell a Troubling Tale

Narwhal Tusks Tell a Troubling Tale

Whatever the purpose, scientists know this for certain: The Arctic region, which the narwhals call home, is warming twice as fast as the rest of the planet, and by analyzing these tusks, researchers can glean surprisingly detailed insights into how the animals are dealing with catastrophic change.

The Mystery of the World’s Loneliest Penguins

The Mystery of the World’s Loneliest Penguins

“We don’t know anything about king penguins at Martillo Island,” says Sami Dodino, a penguinologist at Argentinian scientific institute CADIC.Ushuaia, right at the southern tip of Argentina, is known fondly as “The End of the World.” Travel around 1,000 km south and the next place you reach is Antarctica (although not before passing through another settlement on the Chilean side of the Beagle Channel, Puerto Williams—“Beyond the End of the World”).

NIWA heads to Antarctica for critical climate, ocean research

NIWA heads to Antarctica for critical climate, ocean research

The ship leaves Wellington and heads south with 20 science staff and 19 crew on board to learn more about key environmental and biological processes in the Ross Sea. Voyage leader and fisheries scientist Dr Richard O’Driscoll says this is the third in a series of voyages focused on providing baseline information about the Ross Sea Marine Protected Area (MPA) established in 2017.

An Enormous Iceberg Is Headed for South Georgia Island—Again

An Enormous Iceberg Is Headed for South Georgia Island—Again

A massive Antarctic iceberg is headed straight for South Georgia Island, a remote outpost in the southern Atlantic Ocean that is home to millions of seabirds, penguins, and seals that may find their route to the sea blocked if the Delaware-sized chunk of ice gets stranded near their breeding grounds.

Uh-Oh. Russia's Laptev Sea Should Have Started to Freeze by Now

Ocean temperatures in the area recently climbed to more than 5 C above average, following a record breaking heat wave and the unusually early decline of last winter’s sea ice.The downward trend is likely to continue until the Arctic has its first ice-free summer, said Meier.

What Would Happen If All the Antarctic Ice Melted?

What Would Happen If All the Antarctic Ice Melted?

So what would happen if the global temperature increased enough to melt the ice cap in Antarctica?However, in this case, I really don't have a feeling for the size of the Antarctic ice cap.
