In the remote reaches of Antarctica, the South Pole Observatory carbon dioxide observing station cleared 400 ppm ending the first half of year, according to an announcement from the National Oceanic and Atmospheric Administration recently. That’s the first time it’s passed that level in 4 million years (no, that’s not a typo).
At the bottom of the world, carbon dioxide is doing something surprising. Rising levels of this gas normally cause warming. But over central Antarctica, they produce a cooling. That’s the finding of a new study.
The West Antarctic is one of the most remote places on the planet, but its fate is intimately tied with hundreds of millions living along the world’s coastlines. That’s because it’s frozen expanse contains enough ice to raise sea levels by up to 13 feet.
The West Antarctic sheet is the part of the Antarctic ice cap thought to be easiest to melt. Worries over global warming and sea-level rise lead to it being investigated much more than other parts of the frozen austral continent. Some parts of it, for instance the Pine Island Glacier, have appeared at times to be melting faster and faster, though it is not clear that this is due to global warming.
While it’s no secret that much of the Antarctic Peninsula is rapidly melting, scientists were disappointed when they recently found that a previously stable region of Antarctica is experiencing rapid ice loss – so much so that it is even affecting Earth’s gravity field.
Sea level eventually could rise by at least 11 feet for residents living in the Northern Hemisphere because of a shrinking glacier in the Antarctic, a new science paper revealed recently.
Two boats set out for ‘sighting surveys’ of minke whales after the UN’s top court last year ruled Japan’s annual hunt was illegal.
The Antarctic ice shelf is under threat from a silent, invisible agency – and the rate of melting of glaciers has trebled in the last two decades.
Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long-term satellite record to map sea ice extent in the late 1970s.
A report released recently shows that the world’s ice sheets are melting faster than ever previously recorded, losing about 500 cubic kilometers of ice per year.
A food shortage likely caused by climate change is shrinking a South Antarctic fur seal colony and changing the profile of its surviving members, researchers said recently.
A colossal iceberg roughly six times the size of Manhattan – one of the largest in existence – has been under close watch since it detached from Antarctica’s Pine Island Glacier (PIG) in July.
Japan is cancelling its next Antarctic whaling hunt for the first time in more than 25 years, an official has said, just days after the UN’s International Court of Justice ordered an end to the controversial practice.
In what they are calling the most extreme case of frozen plant regeneration ever documented, scientists are claiming to have regrown shoots of Antarctic moss that were trapped beneath layers of ice and frost for more than 1,500 years.
Strong winds linked to climate change and the hole in the ozone layer are driving a steady increase in Antarctic sea ice, even as Arctic levels continue to shrink dramatically, a new report shows.
