Only Two Penguin Chicks Survive in Catastrophic Antarctic Breeding Season

Only Two Penguin Chicks Survive in Catastrophic Antarctic Breeding Season

Thousands of Adélie penguin chicks in Terre Adélie, Antarctica died of starvation at the start of 2017 due to unusually thick sea ice that forced their parents to travel an extra 100 kilometers (62 miles) to find food, according to French scientists. The colony of over 18,000 pairs of Adélie penguins suffered a “catastrophic breeding […]

    Massive Iceberg Finally Breaks Off: Antarctic Landscape ‘Changed Forever’

    Massive Iceberg Finally Breaks Off: Antarctic Landscape ‘Changed Forever’

    One of the biggest icebergs ever recorded has “finally” broken away from the Larsen C ice shelf in Antarctica, researchers studying the event announced. The iceberg, which will likely be dubbed A68, weighs more than a trillion tonnes, has a volume twice that of Lake Erie, and is about 5,800 square kilometers in size—roughly the […]

    Scientific Research Effort in Arctic Cancelled Due to Climate Change

    Scientific Research Effort in Arctic Cancelled Due to Climate Change

    By Andy Rowell Oh the irony. A scientific expedition examining the effects of climate change has been cancelled because of … climate change. The scientific research effort is being led by world leading Arctic specialist, David Barber from the University of Manitoba, who is joined by 40 scientists from five other universities from across Canada. […]

    Antarctic Warming Threatens World’s Second Largest Ice Shelf

    Antarctic Warming Threatens World’s Second Largest Ice Shelf

    By Tim Radford German scientists have worked out the process that could destroy an Antarctic ice shelf the size of Iraq. They predict that, in a few decades, the oceanographic machinery that keeps the Ronne-Filchner ice shelf in the Weddell Sea will fail. A warm ocean will begin to eat away at the 450,000 square […]

    Giant Waterfall in Antarctica Worries Scientists

    Giant Waterfall in Antarctica Worries Scientists

    By Tim Radford Scientists poring over military and satellite imagery have mapped the unimaginable: a network of rivers, streams, ponds, lakes and even a waterfall, flowing over the ice shelf of a continent with an annual mean temperature of more than -50C. In 1909 Ernest Shackleton and his fellow explorers on their way to the […]

    Massive Iceberg Hangs by 12-Mile ‘Thread’

    Massive Iceberg Hangs by 12-Mile ‘Thread’

    The growing rift in the Antarctic Peninsula has now lengthened to 110 miles, meaning that the Larsen C ice shelf is now connected to the main ice shelf by only a 12-mile “thread,” USA TODAY reports. The British Antarctic Survey determined that the crack has expanded by 50 miles since 2011. “It is particularly hard […]

    Greenland’s Coastal Glaciers Rapidly Withering Away

    Greenland’s Coastal Glaciers Rapidly Withering Away

    Greenland’s icy coastlines are withering away at a rapid pace. With ever rising temperatures in the region, scientists fear the glaciers may never grow back. A team from Ohio State University discovered that about 20 years ago, melting on the island reached a tipping point. In this event, a layer of old snow called the […]
