As world leaders prepare for international climate change negotiations next week in Durban, South Africa, a new study out this week depicts the widespread threats that climate change presents for marine fisheries.
The bottom line? Emissions from the burning of fossil fuels are presenting very long-term if not irreversible threats for the oceans.
Economists and top fisheries scientists at the University of British Columbia published a paper on Sunday in the journal Nature Climate Change that outlines the many challenges fisheries face from climate change, and how this can impact the global economy and hundreds of millions of lives.
Global marine fisheries are underperforming, mainly from rampant overfishing, but climate change also creates several serious threats to the future productivity of fisheries. These chemical and physical changes linked to climate change such as decreased oxygen levels, changes in plankton communities and plant growth, altered ocean circulation and increased acidity can disrupt the basic functioning of marine ecosystems and thwart any potential recovery of global fish stocks.
The study outlines how impacts can scale up from changing ocean conditions to the global economy, but the authors note that the true scope of impacts to employment are hard to predict.
The Arctic’s Northeast Passage is home to walruses, beluga whales, narwhals, and many other marine animals, most of whom have probably never seen an oil tanker or shipping vessel. Unfortunately, thanks to global climate change, that could soon change.
As the planet continues to warm, the coveted Northeast Passage has become ice-free and thus open to cargo ships, oil drillers, and fishing vessels for the first time.
There’s huge incentive for commerce and industry to use the Northeast Passage. The New York Times writes that the opening of the Passage shortens the travel time and reduces costs for shipping between Northern Europe and Asian markets. Companies like Exxon Mobil are attracted to the potential of oil and minerals in the Arctic seabed. And the elusive Arctic “Donut Hole,” a patch of international and unregulated waters in the center of the Ocean, is full of valuable fish including overfished Atlantic cod stocks.
Offshore drilling, increased shipping traffic, and fishing vessels in the Northeast Passage threatens one of the great patches of marine wilderness in the world. Drilling in the Arctic could mean a spill in a place as remote as Northern Russia, which would make the Gulf of Mexico oil spill cleanup look like a cinch, primarily because cleanup mechanisms such as booms don’t work properly in icy waters.
We’ve been campaigning against offshore oil drilling to protect vulnerable Arctic habitats. We'll continue working with local native communities to ensure that future generations will see a healthy and vibrant Arctic. You can help by supporting our work to fight oil drilling in the Arctic.
The latest sea ice data are out, and they aren't pretty. Here’s the latest:
- Scientists at the National Snow and Ice Data Center believe that Arctic sea ice reached its smallest extent for this year on September 9, at 4.33 million square kilometers. If this is the case, the only year since 1979 with less ice was 2007, but they note that if wind conditions change, the area covered by ice may still shrink.
- The University of Washington’s Polar Science Center Arctic ice estimates, which measure volume of ice rather than area, find that this year’s minimum extent is the smallest on record (since 1979), with August sea ice volume at less than half the recorded average.
- NOAA’s National Climatic Data Center has announced that globally this August was the eighth hottest since 1880—and when measuring only land temperatures, August 2011 was the second hottest on record.
The sea ice data in particular are drawing a lot of attention because sea ice maintenance affects weather patterns around the globe, melting ice contributes to warmer oceans and rising sea levels, and unusual ice patterns can wreak havoc on the lives of native humans and animals, particularly polar bears, which can drown, and walruses, which can starve.
This is the eighth in a series of posts about this year’s Ocean Hero finalists.
Today’s featured junior ocean hero finalist is Homer, Alaska native McKenzy Haber, who hosted the first ever TEDxHomer Teen conference in 2010, with a theme of sustainability.
McKenzy and several other teens adapted the TED model to get the word out about ocean conservation to 140 teens and adults in Homer, Alaska and 1,800 livestreaming online. The conference included talks about the oceans, climate change in the Arctic and Antarctica, and ecological economics.
At the 9th World Wilderness Congress, also known as WILD9, he gave a plenary speech called "Dear Developed Earth," to world leaders about teen leadership and protecting wild Alaskan waters. “Many delegates came up to me afterward crying and saying how moving it was,” McKenzy wrote via e-mail. Watch it and see why McKenzy is such an inspiration:
In Al Gore’s “Our Choice: A Plan to Solve the Climate Crisis”, published in November 2009, the former Vice President describes the changes we need to make in technology, business and politics to avert climate catastrophe.
This week, the book got a dramatic digital makeover through the Our Choice App, essentially the first full-length interactive book for iPad, iPhone and iPod touch.
The new app allows you to scroll through all nineteen chapters, zoom into any page, and pick up and pop open any item, including more than 250 photos and 30 interactive infographics and animations.
Anything that makes climate change more visually – and tangibly -- accessible is a great thing in our book (no pun intended.)

Lewis Pugh is a British environmentalist, maritime lawyer and Oceana ally. He was the first person to complete a long distance swim in every ocean, and is probably best known for two impressive feats: his 2007 swim across the North Pole to highlight the melting of Arctic sea ice, and a swim across a glacial lake in the Himalayas 2010 to draw attention to the region’s melting glaciers.
Last week Pugh spoke in Cape Town, South Africa against Shell’s proposed fracking in the country. Fracking, short for hydraulic fracturing, is a method of extracting natural gas by pumping chemicals, sand, and water underground to break apart rock and release gas. (For more on the controversial practice of hydrofracking see Grist and the New York Times.)
While Oceana doesn’t have a campaign directly dealing with the practice of hydrofracking, we are certainly aligned with Pugh on his bottom line: it’s time to transition away from fossil fuels and toward clean energy. Here’s a clip of Pugh’s powerful speech:
Here in the U.S., we need your help to stop dirty energy, too. Please speak up by March 30 (tomorrow!) to prevent new offshore drilling for the next five years.
For millions of years, sea turtles have been a vital part of ocean ecosystems – but today they are on the brink of extinction as a result of irresponsible fishing and habitat destruction, among other threats. We’re working our hardest to save them, but we need your support.
All six sea turtle species that swim in US waters threatened or endangered, but it’s not too late to save them. Donate today and join Oceana in the fight to protect sea turtles and restore ocean balance. With your donation, we will continue pushing for stronger fishing regulations and legislation that will help protect and sustain turtle populations for years to come.
Our goal is to raise $40,000, and we still have a long way to go. Please donate today to help us in the fight to save sea turtles from extinction. And if you’ve already given, thank you -- now pass the word on via Facebook, Twitter, and however else you can!
When you picture the impacts of climate change, what animal comes to mind? Is it a polar bear floating on a thin chunk of ice, or maybe another cold climate species losing habitat like a walrus or a penguin?
Add butterflyfish to your thoughts about climate change, because a new study predicts that they, along with one-third of all coral reef fish, are losing reef habitat and are locally threatened with extinction from climate change.
Coral reefs are threatened by two aspects of carbon dioxide emissions, ocean acidification and climate change. Corals are susceptible to sustained periods of warmer water temperatures due to climate change, which causes them to bleach when they expel algae, turning them white.
Every year the Endangered Species Coalition creates a report that focuses on 10 species facing extinction that are currently listed or being considered for listing under the Endangered Species Act.
This year’s report, It’s Getting Hot Out There: Top Ten Places to Save for Endangered Species, focuses on critical habitats that support endangered species and are themselves threatened by climate change. Shallow water coral reefs and Arctic sea ice, two important habitats that Oceana works hard to protect, were selected as two of the top 10 most important habitats to protect.
Editor’s note: Guest blogger Emily Goldstein was a finalist in Oceana’s first annual Ocean Heroes contest in 2009 for her work to convince thousands of people and dozens of large companies to reduce their energy use, saving 16 million pounds of CO2.
Polar bears stand for everything that is wild and free, ruling over the Arctic as the creature we all associate with the North Pole. They are the apex predators in the Arctic, admired for their power and majesty. But the polar bear has recently become well-known for another, more deadly reason: they have become victims of climate change. Their world of ice is melting away, threatening their very existence.
In November I traveled to a remote town in northern Canada to talk with scientists about the polar bear’s perilous situation. Churchill is a village near the Hudson Bay, where ice first begins to form each year. This was my third visit there, but each time I go I feel even more privileged to be able to experience the world of the bears. The first time I looked into the eyes of a polar bear, I knew that I had to do something to save these amazing creatures from extinction.
