"Rapid loss of Antarctic sea ice could be a tipping point for the global climate, causing sea level rises, changes to ocean currents and loss of marine life that are impossible to reverse, a scientific study published on Thursday said."

"Antarctica’s krill fishery has shut down months ahead of schedule after reaching its full seasonal catch-limit—a historic first. The early closure is fueling urgent calls to protect the Southern Ocean’s fragile marine ecosystems from mounting industrial fishing and climate change."

"Key datasets used to monitor the impacts of climate change in the Arctic have emerged as the latest victim of cost-cutting by the Trump administration at the National Oceanic and Atmospheric Administration."

"Heidi Ahonen is a bioacoustician recording whale calls, whistles and songs to understand if the marine mammals are crossing paths with krill fishing vessels in one of the most extreme environments on Earth."

"Arctic sea ice has recorded its smallest winter peak extent since satellite records began 47 years ago, new data reveals."

"The wildlife charity WWF has been maintaining policies that work to support the trade in polar bear fur at the same time as using images of the bears to raise money, it can be revealed."

"Thousands of years ago, the Arctic was ice-free. What can its past teach us about its future?"

"The Arctic tundra has shifted from storing carbon in the soil to becoming a carbon dioxide source, the National Oceanic and Atmospheric Administration (NOAA) and its partner researchers concluded in their 19th annual Arctic Report Card."

"Alaska’s Arctic National Wildlife Refuge ranks as one of the wildest places on Earth. In the winter, it’s a haven for some of the last polar bears that traverse land and sea. In the summer, millions of birds descend to build their nests and gather fuel for their journey south."
