El Nino washes a SECOND posionous sea snake onto popular California beach which has not seen any for THIRTY YEARS

For the second time in two months, a rare deadly sea snake has washed ashore at one of southern California's most popular beaches.

A dead 27-inch-long male yellow bellied sea snake was discovered last week during a coastal cleanup campaign by volunteers for the Surfrider Foundation in Huntington Beach, the Los Angeles Times reported.

In October, a two-foot-long yellow bellied sea snake was discovered slithering onto Silver Strand State Beach in Ventura County, but it died shortly after being taken to a US Fish and Wildlife Service office nearby.

The venomous sea serpent, known to scientists as Pelamis platura, was first spotted in 1972 during an El Niño in San Clemente.

A descendant of Australian tiger snakes, experts believe the arrival of the sea snake is a harbinger of El Niño because the last time it appeared in California was during the weather system in the '80s.



African lions are to be placed under the protection of the Endangered Species Act, five months after a famous lion named Cecil was killed in Zimbabwe by an American dentist.



 

African lions to join the endangered species list: Five months after Cecil was slain, the animals are to be given special protection

  • Lions in central and west Africa will be listed as endangered
  • While lions found across south and east Africa will be listed as threatened
  • It is hoped the move will make it harder for hunters to bring 'trophies' to US
  • Fish and Wildlife Service said its move is not the result of Cecil outcry 
African lions are to be placed under the protection of the Endangered Species Act, just five months after a famous lion named Cecil was killed in Zimbabwe by an American dentist.

It is hoped the move will better regulate hunting and make it trickier for hunters to bring lion trophies into the US.

Lions in central and west Africa will be listed as endangered, according to the Fish and Wildlife Service, while a second subspecies found across southern and eastern Africa will be listed as threatened.

Both changes will make it harder for hunters to import lion parts.

In particular, importing skins and trophies from countries where the animals are endangered will be 'generally prohibited,' the agency told The New York Times.

The order states the Fish and Wildlife Service will deny a permit to import a sport-hunted lion to anyone who has been convicted or pleaded guilty to violating federal or state wildlife laws.
If this rule had been implemented sooner, it could have potentially prevented the death of Cecil.
In 2008, Walter Palmer, the Minnesota dentist who shot the lion with a bow and arrow earlier this year, pleaded guilty to making false statements to the Fish and Wildlife Service about a black bear fatally shot in western Wisconsin outside an authorised hunting zone.

Under the changes, this would have prevented him getting a permit to travel to Africa and hunt Cecil.

The order states the Fish and Wildlife Service will deny a permit to import a sport-hunted lion to anyone who has been convicted or pleaded guilty to violating federal or state wildlife laws. The move has been made in response to a large decline in the numbers of lions in Africa, rather than in direct response to Cecil's demise

The move has been made in response to a large decline in the numbers of lions in Africa over the past two decades, rather than in direct response to Cecil's demise.

But some claim the creature's very public death was the driving force for many such changes.

Fukui governor to give consent for nuclear plant restart

 
FUKUI —

Fukui Gov Issei Nishikawa will soon give his consent for the restart of two nuclear reactors in the prefecture on the Sea of Japan coast, sources close to the matter said Sunday, as the central government seeks to bring more reactors back online after the 2011 Fukushima nuclear crisis.

The governor will visit the site of the Nos. 3 and 4 reactors at Kansai Electric Power Co’s Takahama plant on Monday to check safety measures before expressing his consent, they said. The governor’s consent is necessary to restart the reactors.

Earlier in the day, industry minister Motoo Hayashi, in charge of the country’s energy policy, met with Nishikawa at the Fukui prefectural office and sought the Fukui governor’s consent for the restart of the two nuclear reactors.

Court Finds Monsanto Responsible for Poisoning French Farmer

The court of appeals in Lyon, France, has found agribusiness giant Monsanto guilty of poisoning a man named Paul François. François is a farmer who claimed that he suffered a multitude of ailments, including headaches, memory loss, neurological problems and stammering, after he unintentionally inhaled Monsanto’s herbicide, Lasso.

François used Lasso for over 15 years, and in 2004 accidentally inhaled the product. After the incident, the farmer began getting severe headaches and experienced moments of mental absence and an inability to speak.

The chemical’s effects on François were so severe that he fainted, was hospitalized and fell into a coma. François was diagnosed with monochlorobenzene poisoning by his doctors, who found that the chemical permanently damaged his brain. Monochlorobenzene makes up 50% of the herbicide Lasso.
It is worth noting that the herbicide was prohibited in France and the rest of the European Union in 2007, and at the time of the incident, it was already banned in Canada (since 1985), Great Britain and Belgium (since 1992).

During the court hearing, Monsanto’s attorneys repeatedly claimed that the herbicide Lasso was not dangerous. François claimed that the company was aware of the toxic nature of the herbicide but failed to adequately warn about the potential health risks.

California Has a Huge Methane Gas Leak of approx. 80,000 tons per month but a fix won't be possible until April, 2016



California Has a Huge Gas Leak, and Crews Can’t Stop It Yet

 While the world was hammering out a historic agreement to curb carbon emissions—urged along by California, no less—the state was dealing with an embarrassing belch of its own. Methane, a greenhouse gas 70 times more potent than carbon dioxide, has been leaking out of a natural gas storage site in southern California for nearly two months, and a fix won’t arrive until spring.

The site is leaking up to 145,000 pounds per hour, according to the California Air Resources Board. In just the first month, that’s added up to 80,000 tons, or about a quarter of the state’s ordinary methane emissions over the same period. The Federal Aviation Administration recently banned low-flying planes from flying over the site, since engines plus combustible gas equals kaboom.
Steve Bohlen, who until recently was state oil and gas supervisor, can’t remember the last time California had to deal with a gas leak this big. “I asked this question of our staff of 30 years,” says Bohlen. “This is unique in the last three or four decades. This is an unusual event, period.”

Families living downwind of the site have also noticed the leak—boy, have they noticed. Methane itself is odorless, but the mercaptan added to natural gas gives it a characteristic sulfurous smell. Over 700 households have at least temporarily relocated, and one family has filed a lawsuit against the Southern California Gas Company alleging health problems from the gas. The gas levels are too low for long-term health effects, according to health officials, but the odor is hard to ignore.

Given both the local and global effects of the gas leak, why is it taking so long to stop? The answer has to do with the site at Aliso Canyon, an abandoned oil field. Yes, that’s right, natural gas is stored underground in old oil fields. It’s common practice in the US, but largely unique to this country. The idea goes that geological sites that were good at keeping in oil for millions of years would also be good at keeping in gas.

Over 15,000 baby sea lions estimated dead as Pacific sea life dies off

Sea lions


(NaturalNews) The Marine Mammal Center rescued over a hundred sea lions in a 10-day period off the West Coast of California in the winter of 2015. The influx of stranded sea lions is a sign that the health of the ocean is deteriorating. From January 1 to February 12, 2015, National Geographic counted nearly 500 rescued sea lions, an amount that is alarming scientists. Something has gone awry in the West Coast waters.

The sea lions are not finding food, they are losing strength, and many are starting to wash ashore. The startling trend didn't start in 2015. The number of stranded sea lions began rising in the winter of 2013, when scientists started noticing waves of sea lion pups washing ashore. Scientists believe the ocean's temperatures have shifted. Warmer currents may be affecting food sources that the sea lions depend on. Others see problems in ocean water acidity. The animals are being forced to go on longer quests to find food. Many of the pups are being left behind, stranded, while their parents search for food.

One-third of sea lions born last summer wiped out

 

The death of this sentinel species is an indication of changes in ocean climate and ecosystem. Sea lion prey, which include sardines and crayfish, are reportedly disappearing in numbers as well, forcing the starving sea lions to go on longer quests in search of food. Scientists are concerned about ocean pH and rising acidity of the waters. According to San Jose Mercury News, marine biologists warn that, if the trend continues, an entire generation of California sea lions could be wiped out.
When speaking to NBC News, Sea World San Diego senior veterinarian Hendrick Nollens reported, "We had rescued 19 California sea lions in January [2013]. This year we already rescued 87 pups in that same month. So this event seems to be much larger."

According to the Daily Breeze, the "unusual mortality event" wiped out two-thirds of the sea lion pup population off the West Coast in 2013.

Rehabilitation centers are taking several hundred pups in this year to save the species from total extinction.

NOAA wildlife biologist Sharon Melin confirmed that most pups captured in the wild in 2013 were only half their weight. After they are released back into the wild, they are expected to maintain their weight. When Melin went on a research trip in September 2013, she reported that the weight of the pups was still low. She brought back the bad news: "We've told the centers to prepare for the worst."
The U-T San Diego concurred, reporting that pups in the Channel Island rookeries continued to struggle despite rehabilitation efforts. On average, pups were 19% below their average weight, even after rehabilitation.

Jim Milbury of NOAA Fisheries says that West Coast sea lions have a birth rate of about 50,000 a year, and San Diego 6 reported on Jan. 28, 2015, that nearly 1 of 3 pups born the previous summer have already died.

If 33% of pups born in 2014 have already died, then based on the average birth rate, over 15,000 have passed away in that short time frame. 

Ocean water acidity on the rise, subjecting aquatic life to disease

 

According to Jennifer Palma of Global News, ocean health is deteriorating, indicated by a die off of scallops and oysters. "Getting pacific oysters and scallops is next to impossible; the industry is in crisis. ... So what's killing the Pacific oysters and scallops? A possible combination of factors including warmer oceans, decreasing acidity levels and potentially disease," she said in a report.
University of British Columbia marine microbiology professor Curtis Suttle is concerned about changes in the pH of ocean waters. "The hypothesis -- there's a working hypothesis --w is that these changes, these excursions in pH, are making the shellfish vulnerable to infection by diseases that they would normally be resistant to."

Monsanto promised that its latest and greatest GM crop would increase yields and stop crop loss due to pests. A new report from the government of Aragon in Spain says those promises are empty.




Report: Monsanto’s Latest GM Maize Doesn’t Reduce Pests or Increase Yields

And it's banned by most of Europe
by Christina Sarich
Posted on December 10, 2015
 
 Monsanto promised that its latest and greatest GM crop, MON810, a genetically modified (GM) insecticidal maize banned by most of Europe, would increase yields and stop crop loss due to pests. A new report from the government of Aragon in Spain says those promises are empty. [1]
 
There is an inserted gene in the DNA of MON810 which allows the plant to make a protein that harms insects that try to eat it. The inserted gene is from the bacterium Bacillus thuringiensis, which produces the Bt toxin that is poisonous to insects in the Lepidoptera order, including the European Corn Borer. [2] Three quarters of the corn grown in Aragon, Spain is currently genetically modified, but conventional varieties were tested against GM Maize varieties in 2014.
 
“Helen,” “Zoom,” and “Kayras” – the non-GM isogenic (parent) lines (plant varieties) – were compared with the GM varieties derived from each line. The genetic insert was the MON810 construct from the US company, Monsanto.
The report found that:
“Per hectare, from 12.6 to 14.3 kg of maize were harvested. The GM varieties and the non-GM conventional comparator had very similar yields – the difference was between 0.2 and 0.3 kilos.”
This means the GM maize did not produce more than conventional strains of maize.

- The Washington Times - Wednesday, December 9, 2015
Interior Secretary Sally Jewell said Wednesday she is unaware of anyone being fired, fined or even demoted for the Gold King Mine spill, prompting Republicans to accuse her of taking the EPA off the hook for the toxic blowout.

“So you’re letting the EPA get off scot-free it sounds like. They are not being held accountable,” said Rep. Doug Lamborn, Colorado Republican, at the House Natural Resources Committee hearing.
Republicans took Ms. Jewell to task for the Interior Department’s investigation into the Aug. 5 spill, saying the October report failed to hold anyone responsible for unleashing 3 million gallons of orange, toxic wastewater into the Animas River near Silverton, Colorado.

“You’re directly responsible for this report. The EPA had promised this committee a thorough investigation,” said Rep. Tom McClintock, California Republican. “We have not gotten one. What we have gotten is a complete, deliberate whitewash.”

'Taningia Danae' or 'whiplash squid' rarely seen alive caught on video footage.



 

Hawaii marine biologists celebrate extremely rare footage of the giant Whiplash squid as it glides through the darkest depths of the Pacific

  • The majestic squid is called 'Taningia Danae' or 'whiplash squid' 
  • Experts say that the whiplash squid has rarely been seen alive 
  • The squid can travel between two and two-and-a-half miles per hour 
  • It attached itself onto a remotely operated underwater vehicle
  • Scientists will study the footage to learn more about the squid
This is the magical moment that National Oceanic and Atmospheric Administration scientists captured footage of a rare deep sea squid.

The majestic sea creature, which is around one to two meters long, is called 'Taningia Danae' or 'whiplash squid.'

As it descended to the sea floor of the Pacific Ocean in Hawaii on September 19, 2015 a remotely operated underwater vehicle caught it on camera.

Botswana's government recently sold the rights to Drill for Shale Gas, in a National Park, to the British Karoo Energy company

Botswana sells fracking rights in national park

Licences for more than half of the Kgalagadi transfrontier park, one of Africa’s largest conservation areas, have been granted to drill for shale gas

The Botswana government has quietly sold the rights to frack for shale gas in one of Africa’s largest protected conservation areas, it has emerged.

The Kgalagadi transfrontier park, which spans the border with South Africa, is an immense 3 6,000 sq km wilderness, home to gemsbok desert antelope, black-maned Kalahari lions and pygmy falcons. But conservationists and top park officials – who were not informed of the fracking rights sale – are now worried about the impact of drilling on wildlife.

Prospecting licences for more than half of the park were granted to a UK-listed company called Nodding Donkey in September 2014, although the sale has not been reported previously. That company changed its name earlier this month to Karoo Energy.

Park officials said that no drilling has yet taken place, but the Guardian found oil sediment on the ground near a popular camp site. There was an overwhelming smell of tar and a drill stem protruded from an apparently recently drilled hole. It is not known who had carried out the drilling or when.
Scientist Gus Mills worked and lived in Kgalagadi for 18 years studying cheetahs and hyenas. He said he is worried about the impact on wildlife and environment.

“The development that is going to have to go on there, with infrastructure that has to be moved in, seems to be yet another nail in the coffin of wild areas in the world.”

Dr Peter Apps, who studies large predators for the Botswana Predator Conservation Trust , said drilling could have a range of impacts, notably on water sources in the park.

Wolves return to Poland more than 50 years after being wiped out

National park outside Warsaw says several of the animals seem to have settled there again after government cull in the 1960s
Wolves have returned to a large national park on the outskirts of Warsaw, decades after they were wiped out there under a hunt launched by the communist authorities.

“We’re really happy,” said Magdalena Kamińska, spokeswoman for the 150sq mile (385sq km) Kampinos national park, Poland’s second largest. “The fact that wolves have returned to our park, from which they completely disappeared in the 1960s, means that nature is in good health and is renewing itself.”

Park employees spotted a first wolf in 2013, but the animal was just passing through. Now there are several and they appear to have settled in for the long haul, Kamińska said.

AquaBounty’s genetically modified (GMO) salmon facing further backlash from national grocery stores and restaurant chains : Costco and Red Lobster Say No to GMO Salmon






Costco and Red Lobster Say No to GMO Salmon

| November 25, 2015 9:21 am |
 
 
The U.S. Food and Drug Administration’s (FDA) controversial approval of AquaBounty’s genetically modified (GMO) salmon has garnered further backlash from national grocery stores and restaurant chains.

Costco, the second largest retailer in the world with 487 stores and one of the largest retailers of salmon and seafood in the U.S., has made a firm commitment not to sell GMO salmon.


gmosalmonfight750


“Although the FDA has approved the sale of GM salmon, Costco has not sold and does not intend to sell GM salmon at this time,” the company said in a statement.

Costco’s move to reject GMO salmon comes after vehement opposition from anti-GMO activists.
According to a statement from Friends of the Earth, Walmart and Publix are among the last remaining large retail grocers in the U.S. that have not yet rejected GMO salmon.

“The market is rejecting GMO salmon. Stores won’t sell it and people don’t want to eat it,” said Friends of the Earth Campaigner Dana Perls. “Now other retailers like Walmart and restaurants need to follow suit, and we need mandatory GMO labeling so that consumers know how to avoid GMO salmon.”

More than 60 grocery store chains representing more than 9,000 stores across the U.S. have made commitments to not sell GMO salmon, including Safeway, Kroger, Target, Trader Joe’s, Whole Foods, Aldi and many others.

The nation’s largest seafood restaurant is also denying GMO salmon. Red Lobster, with 705 North American locations and more than 40 internationally, told the Dallas Morning News that it would not sell GMO salmon last Friday.

Incidentally, consumers might not even know they’re eating GMO salmon. AquaBounty’s salmon, which is genetically altered to grow to market size in half the time of conventional salmon, will not require a GMO label under FDA guidelines.

It’s unclear if we’ll  ever see labels for genetically altered food, period—not just salmon. Currently, the hotly contested Safe and Accurate Food Labeling Act—dubbed by opponents as the Denying Americans the Right to Know Act or DARK Actlanguishes in the Senate.

The act, H.R. 1599, which passed the House of Representatives in July, bans states from issuing mandatory labeling laws for foods containing GMOs. The bill gives the FDA the authority to establish national standards and regulations for GMO food. The Department of Agriculture would be granted full discretion over the law’s implementation.

Next: How NOAA rewrote climate data to hide global warming pause

...................................................................................................

Nasa Earth Observatory

Earth is Cooling…No It’s Warming



In 1967 Hansen went to work for NASA’s Goddard Institute for Space Studies, in New York City, where he continued his research on planetary problems. Around 1970, some scientists suspected Earth was entering a period of global cooling. Decades prior, the brilliant Serbian mathematician Milutin Milankovitch had explained how our world warms and cools on roughly 100,000-year cycles due to its slowly changing position relative to the Sun. Milankovitch’s theory suggested Earth should be just beginning to head into its next ice age cycle. The surface temperature data gathered by Mitchell seemed to agree; the record showed that Earth experienced a period of cooling (by about 0.3°C) from 1940 through 1970. Of course, Mitchell was only collecting data over a fraction of the Northern Hemisphere—from 20 to 90 degrees North latitude. Still, the result drew public attention and a number of speculative articles about Earth’s coming ice age appeared in newspapers and magazines.


Graph of Northern Hemisphere temperatures, 1860 through 1970

Initial efforts to observe Earth’s temperature were limited to the Northern Hemisphere, and they showed a cooling trend from 1940 to 1970 (jagged line). Scientists estimated the relative effects of carbon dioxide (warming, top curve) and aerosols (cooling, bottom curve) on climate, but did not have enough data to make precise predictions. (Graph from Mitchell, 1972.)


But other scientists forecasted global warming. Russian climatologist Mikhail Budyko had also observed the three-decade cooling trend. Nevertheless, he published a paper in 1967 in which he predicted the cooling would soon switch to warming due to rising human emissions of carbon dioxide. Budyko’s paper and another paper published in 1975 by Veerabhadran Ramanathan caught Hansen’s attention. Ramanathan pointed out that human-made chlorofluorocarbons (or CFCs) are particularly potent greenhouse gases, with as much as 200 times the heat-retaining capacity of carbon dioxide. Because people were adding CFCs to the lower atmosphere at an increasing rate, Ramanathan expressed concern that these new gases would eventually add to Earth’s greenhouse effect and cause our world to warm. (Because CFCs also erode Earth’s protective ozone layer, their use was mostly abolished in 1989 with the signing of the Montreal Protocol.)

The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.

Scientific evidence for warming of the climate system is unequivocal.
- Intergovernmental Panel on Climate Change

The current warming trend is of particular significance because most of it is very likely human-induced and proceeding at a rate that is unprecedented in the past 1,300 years.1
 
Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate.

Biodegradable is Bunk: World's 'Ocean Waste Baskets' Still Filled With Plastic Trash

Such products 'will not bring about a significant decrease either in the quantity of plastic entering the ocean or the risk of physical and chemical impacts on the marine environment,' UN report states.

Plastics in the world's oceans, whether floating or resting at the bottom, is a problem that's on the rise, and is said to have "reached crisis proportion."

And while they may be assumed to be more eco-friendly, plastics labeled "biodegradable" still pose a threat to marine environments, a new United Nations study has found.

The report from the UN Environment Programme (UNEP), Biodegradable Plastics and Marine Litter. Misconceptions, Concerns and Impacts on Marine Environments (pdf), explains how these products still fail to tackle the growing problem.

The agency's executive director, Achim Steiner, underscored the magnitude of the problem. "Recent estimates from UNEP have shown as much as 20 million tonnes of plastic end up in the world's oceans each year. Once in the ocean, plastic does not go away, but breaks down into microplastic particles."

The report notes that just what proportion of this plastic is biodegradable versus non-biodegradable has yet to be analyzed.

One of the problems, the report states, is that in order for some of the plastic debris to be completely broken down, conditions found in industrial compositing units that can achieve prolonged temperatures of above 50°C are needed. Yet those conditions "are rarely if ever met in the marine environment."

And while some have the inclusion of a pro-oxidant, which would induce degradation, "[t]he fate of these fragments (microplastics) is unclear, but it should be assumed that oxo-degradable polymers will add to the quantity of microplastics in the oceans, until overwhelming independent evidence suggests otherwise."

Contributing to the problem, the report says, is evidence suggesting the biodegradable label could make the public more likely to litter.

The report concludes that "the adoption of plastic products labelled as 'biodegradable' will not bring about a significant decrease either in the quantity of plastic entering the ocean or the risk of physical and chemical impacts on the marine environment, on the balance of current scientific evidence."
Peter Kershaw, one of the authors of the study, put the problem in blunt terms.

"Essentially the ocean is being used as a waste basket and the waste basket is getting fuller and fuller, and so the impacts of that plastic litter are just going to keep on increasing," he toldCBC News.

With their red heads, 2.13-meter (7-foot) wingspan and a trilling call, migrating Sandhill Cranes provide a dramatic sunset spectacle as they land by the thousands in wetlands near Sacramento each night during the fall and winter.

But the state's ongoing drought has left the cranes, along with millions of other waterfowl that migrate from Canada and other northern climes to spend the winter in California, with fewer places to land, threatening their health as they crowd in on one another to seek shelter and food.

"They're left with fewer and fewer places to go, which will start to have impacts on their population," said Meghan Hertel, who works on habitat issues for the Audubon Society in California. "They can die here from starvation or disease or be weaker for their flight back north."


Beloved sight


The cranes are a beloved sight in California's Sacramento and San Joaquin Valleys when they arrive each fall.

Tourists flock to see them as they take off en masse at dawn or land in a series of swooping, trilling groups as the sun goes down.

They are our closest living relatives in the animal kingdom, yet more than half of the world's primates are facing extinction due to our destruction of the habitats where they live.
Burning and clearing of large areas of tropical forest, combined with hunting of primates for food and illegal wildlife trade, has placed many species of apes, lemurs and monkeys at risk of dying out.
These include iconic species such as the Sumatran orang-utan, Grauer's gorilla, the Northern brown howler monkey and the Hainan gibbon.
More than half of the world's primates are at risk of dying out due to the threat posed by habitat loss and hunting. The Hainan gibbon (pictured) is thought to be the world's most endangered primate, with just 25 of the animals left living on an isolated island in China
