Storm surges, rising seas could doom Pacific islands this century

Ocean Conserve - Sat, 04/13/2013 - 14:00
ClimateWire: As ice caps melt and sea levels rise, islands around the world could eventually become completely submerged, like real-world cities of Atlantis. Scientists have determined that the tides could consume low-lying islands in the next 50 to 150 years. But they'll become uninhabitable well before they're underwater, and that day might not be in the too distant future. A study by the U.S. Geological Survey released yesterday finds that the two northwestern Hawaiian atolls of Midway and Laysan and...

In Washington, Clamming for Food and Tradition

Ocean Conserve - Sat, 04/13/2013 - 00:39
New York Times: Some razor clammers take a methodical line, a slow, eyes-down stroll through the outgoing tide, watching for the telltale quarter-size divot that marks a clam’s hiding spot, two feet or so below the surface. At age 82, John Lavender takes that approach. He walked the beach here on Friday just after 7 a.m. with the cool calm of a clam digger’s wisdom, born of 50 years’ experience. Then there’s Garrett Lavender, 12, his grandson. For Garrett, digging razor clams is all about the fast-twitch muscles:...

Arctic Ocean to be ice-free during summers before 2050

Ocean Conserve - Fri, 04/12/2013 - 19:44
Mother Nature Network: By the time today's babies graduate college, there's a very good chance they could celebrate with a cruise across the North Pole. That's according to the latest study on Arctic summer sea ice, the frozen pack that lingers through the Northern Hemisphere summer. In past decades, there's been less summer ice, and it's growing thinner. The research, published online Feb. 21 in the journal Geophysical Research Letters, says major sea ice loss could come within a decade or two, though some ice will...

Arctic nearly free of summer sea ice during first half of 21st century

Ocean Conserve - Fri, 04/12/2013 - 19:15
ScienceDaily: For scientists studying summer sea ice in the Arctic, it's not a question of "if" there will be nearly ice-free summers, but "when." And two scientists say that "when" is sooner than many thought -- before 2050 and possibly within the next decade or two. James Overland of NOAA's Pacific Marine Environmental Laboratory and Muyin Wang of the NOAA Joint Institute for the Study of Atmosphere and Ocean at the University of Washington, looked at three methods of predicting when the Arctic will be nearly...

Study: Arctic Summers Warmest in 600 Years

Ocean Conserve - Fri, 04/12/2013 - 19:00
Climate Central: The Arctic has seen warmer summers over the past two decades than at any time in the past 600 years, according to a study published this week in the journal Nature. The study uses a sophisticated statistical approach, known as Bayesian modeling, to show that the extremely warm summers in high northern latitudes are evidence of an overall warming trend, rather than just a temporary fluctuation in an otherwise unchanging climate. That’s a crucial distinction: a natural fluctuation might reverse before...

Shell’s Plot to Silence Protests Against Arctic Drilling

Ocean Conserve - Fri, 04/12/2013 - 18:23
EcoWatch: Corporations want to work in secret. It`s what they do, and why they have lawyers. In secret, they can spill, clearcut, burn and otherwise destroy the environment and local communities while telling the world they`re doing just the opposite. Shell Oil`s legal team is currently working overtime to keep the company`s Arctic work secret from advocacy groups like Greenpeace. It`s a battle that will have implications well beyond the Far North. If Shell ultimately wins the legal battle with us this month,...

New Diseases, Toxins Harming Marine Life

Ocean Conserve - Fri, 04/12/2013 - 17:56
National Geographic: The dead sea otters arrived at Melissa Miller's Santa Cruz, California, lab with bright-yellow eyes and gums, their livers destroyed. One by one, Miller, a marine-wildlife veterinarian, eliminated the potential causes of death until "the last thing I was left with seemed so implausible that I thought I was going crazy." The otters had been poisoned by a "nasty toxin" called microcystin, which is produced by cyanobacteria, or blue-green algae. Such toxins can appear when human sewage and fertilizers...

United Kingdom: RSPCA rescues dozens of birds covered in sticky substance

Ocean Conserve - Fri, 04/12/2013 - 17:49
Independent: Dozens of birds have been recovered from beaches in the south west covered in an oily substance, three months after more than 300 birds were affected by oil pollution, suspected to have seeped from chemical tankers. Nearly 90 birds have been collected by a team of six RSPCA inspectors on beaches from Mevagissey, Plymouth, Looe and Whitsand Bay. A number of birds taken in by West Hatch wildlife centre in Taunton were in such a bad condition they had to be put to sleep. The RSPCA said that the current...

Climate Change Seen Leaving Arctic Ice-Free by 2050

Ocean Conserve - Fri, 04/12/2013 - 16:12
Bloomberg: The Earth’s northern polar region will be almost ice-free in the warmest months by 2050, sooner than previously estimated, according to a study by two federal government scientists who work on climate change. The researchers from the National Oceanic and Atmospheric Administration used three separate methods to predict the sea- ice trends in the Arctic Ocean, and their estimates for 2020 to 2060 forecast elimination of most ice during the Northern Hemisphere’s warmest months, according to a statement....

Many Marine Mammal Species Rebounded Since 1972 U.S. Protections

Ocean Conserve - Fri, 04/12/2013 - 16:00
Yale Environment 360: Forty years after the passage of the Marine Mammal Protection Act (MMPA), no marine mammal species in U.S. waters has been extirpated and the populations of many marine animals are more abundant than in 1972, a new study says. While many species, including the endangered right whale, remain at significant risk, the populations of other species -- including gray seals in New England and sea lions and elephant seals on the Pacific coast -- have “recovered to or near their carrying capacity,” scientists...

New York Times: Please look below for a "Your Dot" missive on an emerging force that will, in ways both direct and indirect, shape the face of what we used to call "nature" or "wildlife." The post was sent by Cristián T. Samper, the president of the Wildlife Conservation Society, from a meeting held this week at Cambridge University to examine this question: "How will Synthetic Biology and Conservation Shape the Future of Nature?" There`s a superb and detailed framing paper for the meeting posted here. WCS...

Global warmth: Oceans are taking it all in

Ocean Conserve - Fri, 04/12/2013 - 14:00
USA Today: The temperature of Earth's atmosphere has been essentially the same for the past decade or so, providing ammunition for skeptics of human-caused climate change. (This despite the fact that of the nine hottest years on record, eight have occurred since 2000, according to the National Climatic Data Center). However, a recent study found that heat absorbed by Earth's oceans has increased significantly over the same period, prompting the study co-authors to say that the warming has been diverted and...

Better rankings of climate vulnerability needed - experts

Ocean Conserve - Fri, 04/12/2013 - 08:43
AlertNet: Which fares worse in a world of climate shifts, drought-ridden Burundi or flood-prone Bangladesh? As poorer countries are hit by the effects of climate change and their resources to respond remain inadequate, richer nations have promised $100 billion a year by 2020 to help them adapt to the impacts and try to curb their own climate-changing emissions. But experts say dividing up the money requires answering one very tough question: Who is the most vulnerable to climate change? Given the urgency...

Meteorologists retire 'Sandy' from list of hurricane names

Ocean Conserve - Fri, 04/12/2013 - 08:00
Reuters: The World Meteorological Organization has retired "Sandy" from its rotating list of hurricane names because of the devastation last year's storm by that name caused in Jamaica, Cuba and the northeastern United States, forecasters said on Thursday. Atlantic and Pacific storm names are reused every six years but are retired "if a storm is so deadly or costly that the future use of the name would be insensitive or confusing," forecasters at the U.S. National Hurricane Center in Miami said. Sandy...

New genetic test shows up fish mislabelling

Ocean Conserve - Fri, 04/12/2013 - 06:29
PlanetEarth: Scientists have found a new way of testing for the genes of particular kinds of fish quickly, cheaply and accurately. The breakthrough will benefit marine ecology, where it's already shown that the mix of fish larvae in the English channel is different from what we thought, and could also help detect mislabelled fish - in fact, it's already done so, spotting fraudulent so-called anchovies, sardines and sprat. The new method can distinguish between different species at stages of life when they...

TEPCO Plans for Storing Radioactive Water Dealt Heavy Blow

Ocean Conserve - Fri, 04/12/2013 - 04:00
Asahi Shimbun: Radioactive water continues to leak from tanks at the crippled Fukushima nuclear plant. Space is running out to store the hundreds of tons of contaminated water produced each day. And the initial plan to address the growing water problem now appears flawed. That is the situation facing plant operator Tokyo Electric Power Co., which on April 9 admitted to another leak in an underground storage tank holding contaminated water. The discovery at the No. 1 tank may force TEPCO to change its emergency...
