Chilling: Arctic explorer Yamazaki sees climate change impact up close

Ocean Conserve - Wed, 04/17/2013 - 16:37
Japan Times: Spending six months of every year in the Arctic, adventurer Tetsuhide Yamazaki sees the impact of global warming firsthand through the region`s thinning sea ice, the expanse of which has roughly halved in the last three decades. The ice is "very thin this year," Yamazaki, 45, said after confirming a thickness of 118 cm with a drill during his recent exploration of an area at the North Pole. Sea ice in the area is usually almost 2 meters thick, according to Yamazaki, who senses the ice grows thinner...

Seabirds affected by second wave of sticky pollution 'could number thousands'

Ocean Conserve - Wed, 04/17/2013 - 15:59
Guardian: The numbers of seabirds affected by a sticky substance in the sea off south-west England over the past week could be far greater than those harmed by a similar – or possibly the same – spill earlier this year. Wildlife agencies in Devon and Cornwall said numbers of birds killed or rendered helpless could reach "thousands" and that "a whole generation of seabirds" may have been wiped out in a single pollution incident. Dead and distressed birds have been washing up along beaches in Devon and...

Extinction debt suggests endangered species are doomed

Ocean Conserve - Wed, 04/17/2013 - 14:39
New Scientist: From dragonflies to bears, when it comes to lost species we ain't seen nothing yet. Biologists are getting rattled about growing evidence of "extinction debt" - the idea that there is a delay of decades or even centuries between humans damaging ecosystems and the demise of species that live there. In the largest extinction debt study to date, Stefan Dullinger of the University of Vienna, Austria, ranked 22 European countries according to the proportion of domestic species classed as endangered...

Can Nutrient Trading Shrink the Gulf of Mexico's Dead Zone?

Ocean Conserve - Wed, 04/17/2013 - 14:31
World Resources Institute: The Gulf of Mexico has the largest dead zone in the United States and the second-largest in the world. Dead zones form when excessive amounts of nitrogen and phosphorous wash into waterways and spur algal blooms, depleting the water of oxygen and killing fish, shrimp, and other marine life. The Gulf of Mexico dead zone can range between an astounding 3,000 and 8,000 square miles. At its largest, it’s about the size of Massachusetts. Reducing this growing dead zone problem is a huge scientific,...

Arctic Nations Seek Common Management of Fishing as Open Water Spreads

Ocean Conserve - Wed, 04/17/2013 - 14:27
New York Times: Humanity has long had a two-pronged reaction to environmental change — girding against risks but also probing for opportunities. The spread of ice-free Arctic Ocean waters in summer is eroding shorelines and may be affecting Northern Hemisphere winter weather (the jury is out). But of course this change has also prompted enterprising shippers to test new trade shortcuts and led to projections of bountiful new fisheries. Luckily, the nations ringing the Arctic are recognizing the importance of going...

Wind Power Opponents May Be Blowing Hot Air

Ocean Conserve - Wed, 04/17/2013 - 14:18
EcoWatch: Opposition to windmills often centers on health effects, but what is it about wind power that causes people to feel ill? According to recent research, it may not be the infrasound from wind-energy installations but, oddly enough, the warnings from opponents. For a study published in the American Psychological Association’s Health Psychology journal, researchers from New Zealand’s University of Auckland showed readily available anti-wind-power film footage to 27 people. Another 27 were shown interviews...

Is Ice Loss by Glaciers Abnormal?

Ocean Conserve - Wed, 04/17/2013 - 13:31
ScienceDaily: In the last few decades, glaciers at the edge of the icy continent of Antarctica have been thinning, and research has shown the rate of thinning has accelerated and contributed significantly to sea level rise. New ice core research suggests that, while the changes are dramatic, they cannot be attributed with confidence to human-caused global warming, said Eric Steig, a University of Washington professor of Earth and space sciences. Previous work by Steig has shown that rapid thinning of Antarctic...
