Adélie penguins are “iconic symbol of climate change”

By Midge Raymond,

This video, with gorgeous images of Adélie penguins and their chicks on the Antarctic peninsula, is one of the best calls to action I’ve seen for a planet in peril due to climate change.

 

 

Excerpted from James McClintock’s Lost Antarctica and narrated by Harrison Ford (member of the E.O. Wilson Biodiversity Foundation (EOWBF) Board of Advisors), this brief video shows how the amazing Adélie penguin is being threatened by real-time environmental changes.

Over the last six decades, scientists have observed an average increase of 2 degrees Fahrenheit per decade in the Antarctic peninsula. These warming temperatures lead to increasing humidity, which leads to unseasonable snow. This video shows Adélies trying to keep their eggs incubated despite being buried in snow.

What sort of a world will future generations of Antarctic scientists find when they come to this remarkable place? When they gaze over this landscape, will they be reminded how this place, this peninsula, these ecosystems, served as a wake-up call…?

Climate change isn’t an abstract, faraway notion. It’s happening before our eyes, chick by chick.

The truth about Antarctica’s ice

By Midge Raymond,

A recent NASA study has been making headlines because it has revealed that Antarctica is gaining ice rather than losing it (which contradicts other studies, including one by the Intergovernmental Panel on Climate Change). And yet…

“We’re essentially in agreement with other studies that show an increase in ice discharge in the Antarctic Peninsula and the Thwaites and Pine Island region of West Antarctica,” said Jay Zwally, a glaciologist with NASA Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study, which was published on Oct. 30 in the Journal of Glaciology.

And, while the study shows ice gain in East Antarctica and the interior of West Antarctica, it may not make much of a difference in the end. Zwally notes, “If the losses of the Antarctic Peninsula and parts of West Antarctica continue to increase at the same rate … I don’t think there will be enough snowfall increase to offset these losses.”

In addition, while NASA concludes that Antarctica isn’t currently causing a rise in the oceans, this means that there’s another contributor out there.

“The good news is that Antarctica is not currently contributing to sea level rise, but is taking 0.23 millimeters per year away,” Zwally said. “But this is also bad news. If the 0.27 millimeters per year of sea level rise attributed to Antarctica in the IPCC report is not really coming from Antarctica, there must be some other contribution to sea level rise that is not accounted for.”

And while it’s heartening to know that Antarctica is colder and snowier than previously believed, this doesn’t mean we can ignore climate change. This New York Times article portrays the results of a study with a stark headline: Study Predicts Antarctica Ice Melt if All Fossil Fuels Are Burned. As one of the study’s researcher notes, “To be blunt: If we burn it all, we melt it all.”

In other words, the scientists at the Potsdam Institute for Climate Impact Research concluded, if we continue to burn the earth’s fossil fuels, all of its land ice will melt — not only Antarctica — and the total rise in sea level could be more than 200 feet. The New York Times spells out what this new world would look like:

A sea level rise of 200 feet would put almost all of Florida, much of Louisiana and Texas, the entire East Coast of the United States, large parts of Britain, much of the European Plain, and huge parts of coastal Asia under water. The cities lost would include Miami, New Orleans, Houston, Washington, New York, Amsterdam, Stockholm, London, Paris, Berlin, Venice, Buenos Aires, Beijing, Shanghai, Sydney, Rome and Tokyo.

This piece in National Geographic sums up NASA’s study with a Q&A that shows global warming isn’t something we can ignore. As University of Alaska, Fairbanks glaciology professor Erin Pettit tells National Geographic, “adding a little snow to Antarctica in no way offsets the complete disintegration of the West Antarctic ice sheet in the near future.”

In other words, despite some potentially good news about our southern continent, the problem of global warming is here to stay, and we must take better care of this planet. The very good news is that we can all make a difference — with our habits, our diets, our votes, and our wallets.

Saving Antarctica’s krill

By Midge Raymond,

This New York Times story about the threat to Antarctica’s krill is quite alarming. Laboratory research is showing that krill eggs can’t survive increases in carbon dioxide, a condition that mimics the acidification of the ocean due to global warming. Dr. So Kawaguchi has been studying krill for 25 years, and as the Times notes, his “recent research has led to dire predictions about how global carbon emissions will significantly reduce the hatch rates of Antarctic krill over the next 100 years.”

In fact, Kawaguchi told the Times: “If we continue with business as usual, and we don’t act on reducing carbon emissions, in that case, there could be a 20 to 70 percent reduction in Antarctic krill by 2100…By 2300, the Southern Ocean might not be suitable for krill reproduction.”

Krill are already being vacuumed from the sea by commercial fishing trawlers and used to feed farmed fish as well as for oil supplements for humans. And these activities take food from the mouths of those who need krill the most: whales and penguins, sea birds and squid.

For the fifth year in a row, the Commission for Conservation of Antarctic Marine Living Resources (CCAMLR) is discussing the creation of a Marine Protected Area (MPA) in the Antarctic. At 1.25 million square kilometers, it would be the biggest MPA in the world.

Meanwhile, we can all do our part — by avoiding farmed seafood that depletes the Antarctic krill (and if you need further inspiration to give up farmed fish, this post on the conditions in which farmed fish are raised should do it), and also by choosing plant-based supplements, which helps protect all creatures, which in turn helps protect us. As Sea Shepherd founder Paul Watson is known for saying, “If the oceans die, we die.” And he is right.



Book publishing in Antarctica

By Midge Raymond,

Of all that Antarctica is known for, who knew it was once a publishing hub? (Well, sort of.)

I’ve been reading about the Aurora Australis — the first book ever written, printed, illustrated, and bound in Antarctica — soon to be offered at auction by Sotheby’s and expected to bring in £70,000.

Aurora Australis was produced during Shackleton’s Nimrod Expedition of 1908–09, at Cape Royds on Ross Island in the McMurdo Sound. It was one of many activities Shackleton encouraged of his team so that “the spectre known as ‘polar ennui’ never made its appearance.”

What’s interesting is that by the time this book was created, publishing was not a new thing in the polar regions. Already explorers were publishing articles and newspapers detailing their expeditions — from Edward Parry’s 1819 expedition in search of the Northwest Passage to the South Polar Times, published during Robert Scott’s Discovery and Terra Nova expeditions. And now, of course, you can go online to read the news of what’s happening in Antarctica — for example, The Antarctic Sun, published by the U.S. Antarctic Program; and blog posts from the British Antarctic Survey.

Shackleton’s Nimrod expedition was sponsored by a printing firm, and Shackleton received training and traveled south with a printing press and paper. (Click here to learn more about the challenges of printing in the extreme temperatures of the Antarctic.)

Aurora Australis, which will be auctioned in London on September 30, is 120 pages long and contains poems, stories, essays, and illustrations by ten members of the expedition. Horse harnesses were recycled to create the leather spines, and the covers of the copy up for auction were made from a tea chest. Only eighty copies of the book were printed.



Pirates v. pirates on lawless oceans

By Midge Raymond,

It’s been great to see stories about illegal fishing on the front pages of two major newspapers over the past week. Overfishing is one of the biggest dangers facing our oceans … and yet, often there is little that can be done, as this front-page Los Angeles Times story points out. This is why the Sea Shepherd Conservation Society’s work is so vital; as the organization puts it: “It takes a pirate to catch a pirate.”

The LA Times story focuses on the Kunlun, “a decrepit fishing vessel, its huge white hull streaked with filth and rust,” which was suspected of holding $5 million worth of illicit Patagonian toothfish, better known by its more user-friendly name “Chilean sea bass,” a fish whose stocks have been dangerously depleted due to overfishing and is now considered a threatened species. After the market for Chilean sea bass boomed in the 1990s, by the year 2000 twice as much of the fish was being caught illegally.

This article, as well as yesterday’s New York Times cover story, feature the Sea Shepherd’s efforts to end illegal fishing (as well as whaling and other atrocities against marine life) in international waters where poachers are rampant. The NYT piece focuses on the Sea Shepherd’s 110-day pursuit of the Thunder, a trawler considered the world’s most notorious fish poacher, via the Bob Barker.

As the Times points out:

Industrial-scale violators of fishing bans and protected areas are a main reason more than half of the world’s major fishing grounds have been depleted and by some estimates over 90 percent of the ocean’s large fish like marlin, tuna and swordfish have vanished. Interpol had issued a Purple Notice on the Thunder (the equivalent of adding it to a Most Wanted List, a status reserved for only four other ships in the world), but no government had been willing to dedicate the personnel and millions of dollars needed to go after it.

So Sea Shepherd did instead, stalking the fugitive 202-foot steel-sided ship from a desolate patch of ocean at the bottom of the Earth, deep in Antarctic waters, to any ports it neared, where its crews could alert the authorities.

It’s wonderful to see the Sea Shepherds getting such positive press for the important work they do. “Maritime lawyers question whether the group has legal authority for its actions — ranging from cutting nets and blocking fishermen to ramming whaling vessels — but Sea Shepherd claims its tactics are necessary. So do some Interpol officials.” In waters where no Coast Guard exists and where poachers will change a ship’s name and port registry up to a half-dozen times, as Australian senator Peter Whish-Wilson told the Times, “Sea Shepherd is doing what no one else will.”

Learn more about the Sea Shepherds and how they help protect the oceans … and, even better, help solve the problem at its roots by not eating fish (this article makes a good case for avoiding fish; these 99 reasons not to eat fish include endangered species as well as important health concerns; and this infographic shows the environmental and ethical impacts of the seafood industry).
