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.

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

 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.

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

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.

A third strange black orb has fallen from space. The circular 50lb objects crash into a rural Spanish village




THIRD mystery 'Death Star' space ball to crash into Spanish village sparks terror among locals as mayor demands authorities explain what they are

  • A third strange black orb has fallen from space into a rural Spanish village 
  • Concerned locals and Villavieja's mayor have demanded an explanation
  • The circular 50lb objects bear a strange resemblance to a Star Wars droid
A third mysterious black space object to fall from the sky into rural Spain has caused panic among locals.

The strange-looking black orb was found in the village of Villavieja in Murcia - becoming the latest instance of an increasingly bewildering phenomenon, the Olive Press reported.

It's not yet known what the objects are, though theories range from UFOs to pieces of space debris.
The first instance of the strange phenomenon occurred one week ago, when Spanish goat farmers discovered the strange object, which bears a striking resemblance to the Star Wars torture device, the IT-O Interrogator, in Calasparra, Murcia.
The Civil Guard were called to investigate the black orb and the area was subsequently put under quarantine. Pictured is the second object to be found in the village earlier this week

The Civil Guard stated the object was an aerospace artefact and pointed to the possibility that it fell from a rocket or a satellite.

However, a few days later a second orb fell from the sky.

According to The Mirror, Jose Velez, the mayor of Calasparra, implored authorities to provide answers to worried residents.

'Where are these objects coming from? Why are they falling here precisely?'

More than a mile beneath the ocean's surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war.
Like pirates boarding a treasure-laden ship, the viruses infect bacterial cells to get the loot: tiny globules of elemental sulfur stored inside the bacterial cells.
Instead of absconding with their prize, the viruses force the bacteria to burn their valuable sulfur reserves, then use the unleashed energy to replicate.
"Our findings suggest that viruses in the dark oceans indirectly access vast energy sources in the form of elemental sulfur," said University of Michigan marine microbiologist and oceanographer Gregory Dick, whose team collected DNA from deep-sea microbes in seawater samples from hydrothermal vents in the Western Pacific Ocean and the Gulf of California.
"We suspect that these viruses are essentially hijacking bacterial cells and getting them to consume elemental sulfur so the viruses can propagate themselves," said Karthik Anantharaman of the University of Michigan, first author of a paper on the findings published this week in the journal Science Express.
Similar microbial interactions have been observed in shallow ocean waters between photosynthetic bacteria and the viruses that prey upon them.
But this is the first time such a relationship has been seen in a chemosynthetic system, one in which the microbes rely solely on inorganic compounds, rather than sunlight, as their energy source.
"Viruses play a cardinal role in biogeochemical processes in ocean shallows," said David Garrison, a program director in the National Science Foundation's (NSF) Division of Ocean Sciences, which funded the research. "They may have similar importance in deep-sea thermal vent environments."

Preglacial landscape found deep under Greenland ice

ICE WORLD

Preglacial landscape found deep under Greenland ice


by Staff Writers
Washington (AFP) April 18, 2014

US geologists said Thursday they have uncovered a preglacial tundra landscape preserved for 2.7 million years far below the Greenland ice sheet.
Glaciers are known to scrape everything off any given plot of land -- vegetation, soil and even the top layer of bedrock -- so scientists expressed great surprise that they had found the landscape in pristine condition below two miles (three kilometers) of ice.
The finding provides strong evidence that the ice sheet has existed for much longer than previously known, and survived numerous global warming episodes, according to the lead researcher, University of Vermont geologist Paul Bierman.
Rather than scraping and sculpting the landscape, the ice sheet has been frozen to the ground, effectively creating "a refrigerator that's preserved this antique landscape," Bierman said.
The finding suggests that even during the warmest periods of the ice sheet's life, the center of Greenland was stable and did not fully melt, allowing the tundra landscape to be sealed without modification through millions of years of changing temperatures.

Massive canyon discovered buried under Greenland ice

A vast gorge in the Earth on the same scale as the Grand Canyon lies buried under ice in Greenland, scientists have learned.
The massive hidden canyon is at least 466 miles (740km) long and up to 800 metres (2,600ft) deep in places.
The feature, resembling a meandering river channel, is believed to pre-date the ice sheet that has covered Greenland for millions of years.

Prof Jonathan Bamber, from the school of geographical studies at the University of Bristol, said: "With Google Streetview available for many cities around the world and digital maps for everything from population density to happiness, one might assume that the landscape of the Earth has been fully explored and mapped.
"Our research shows there's still a lot left to discover."
The canyon was uncovered by airborne radar which can penetrate ice and bounce off the land beneath.
Scientists pieced together radar measurements covering thousands of kilometres collected by Arctic researchers over several decades. They found evidence of a fissure in the bedrock stretching northwards almost from the centre of Greenland.
The canyon ends in a deep fjord connecting it to the Arctic ocean.

New Research Shows Tree Roots Regulate CO2, Keep Climate Stable


Climate News Network | February 19, 2014 8:30 am


The argument, put forward by a team from Oxford and Sheffield Universities in the journal Geophysical Research Letters, begins with temperature. Warmer climates mean more vigorous tree growth and more leaf litter, and more organic content in the soil. So the tree’s roots grow more vigorously, said Dr. Christopher Doughty of Oxford and colleagues.
They get into the bedrock, and break up the rock into its constituent minerals. Once that happens, the rock starts to weather, combining with carbon dioxide. This weathering draws carbon dioxide out of the atmosphere, and in the process cools the planet down a little. So mountain ecosystems—mountain forests are usually wet and on conspicuous layers of rock—are in effect part of the global thermostat, preventing catastrophic overheating.
The tree is more than just a sink for carbon, it is an agency for chemical weathering that removes carbon from the air and locks it up in carbonate rock.
That mountain weathering and forest growth are part of the climate system has never been in much doubt: the questions have always been about how big a forest’s role might be, and how to calculate its contribution.
Keeping climate stable
U.S. scientists recently studied the rainy slopes of New Zealand’s Southern Alps to begin to put a value on mountain ecosystem processes. Dr. Doughty and his colleagues measured tree roots at varying altitudes in the tropical rain forests of Peru, from the Amazon lowlands to 3,000 meters of altitude in the higher Andes.
They measured the growth to 30 cm below the surface every three months and did so for a period of years. They recorded the thickness of the soil’s organic layer, and they matched their observations with local temperatures, and began to calculate the rate at which tree roots might turn Andean granite into soil.
Then they scaled up the process, and extended it through long periods of time. Their conclusion: that forests served to moderate temperatures in a much hotter world 65 million years ago.

​Bees exposed to "field-realistic" doses of insecticides gather less than a half the pollen that they normally do, dooming their young to starvation, state UK researches

Starving hives: Pesticides cause bees to collect 57% less pollen, study says

 While some scientists hailed the findings, pesticide makers remained unimpressed

In a spin-off of their earlier study, a team of British scientists have revealed how the neurotoxic chemicals contained in agricultural neonicotinoids affect the very basic function of the honeybees – the gathering of pollen, or flower nectar.
“Pollen is the only source of protein that bees have, and it is vital for rearing their young. Collecting it is fiddly, slow work for the bees and intoxicated bees become much worse at it. Without much pollen, nests will inevitably struggle,” explained University of Sussex professor Dave Goulson, who has led the study. His comments were made in a statement released alongside the research.
Goulson’s latest paper called “Field realistic doses of pesticide imidacloprid reduce bumblebee pollen foraging efficiency” was published at the end of January in peer-reviewed journal Ecotoxicology.
The scientists exposed some of the studied bees to low doses of imidacloprid and tracked their movement with the help of electronic tags. Unexposed bees were also tracked, and each insect flying out and returning to a hive was weighed to find out the amount of pollen it gathered.
It turned out that bees exposed to the neonicotinoid brought back pollen from only 40 percent of their trips asopposed to 63 percent of useful trips which their “healthy” counterparts undertook.
Intoxicated bees cut the amount of pollen gathered by nearly a third - overall, the comparative study showed that the hives exposed to the pesticide received 57 percent less pollen.
“Even near-infinitesimal doses of these neurotoxins seem to be enough to mess up the ability of bees to gather food. Given the vital importance of bumblebees as pollinators, this is surely a cause for concern,” Hannah Feltham of the University of Stirling, another member of the research team, stated.

Greenland's First Coral Reef Found

A Canadian research ship sampling water near southwest Greenland's Cape Desolation discovered the Greenland coral reef in 2012, when its equipment came back to the surface with pieces of coral attached.
"At first, the researchers were swearing and cursing at the smashed equipment, and were just about to throw the pieces of coral back into the sea, when luckily, they realized what they were holding," Helle Jørgensbye, a doctoral student at the Technical University of Denmark who is studying the reef, said in a statement.

Cold-water corals have been found off of Greenland's west coast before, but never the stone coral Lophelia pertusa, and never as a reef, according to a report by the researchers published in the journal ICES Insight.
Scientists snapped pictures of the reef and collected coral samples on a return trip, also in 2012, led by the Bedford Institute of Oceanography in Nova Scotia.

Bit chilly for snorkelling! Living coral reef is discovered off the coast of GREENLAND

  • 'Cold-water' coral discovered in Cape Desolation, south of Ivittuut
  • It is the first time an entire reef has been discovered in Greenland
  • It was discovered by Canadian researchers purely by accident

Coral reefs are often associated with tropical climates and enjoyed by snorkellers for their multi-coloured beauty.
But it would take a brave holidaymaker indeed to brave the one recently discovered by Canadian researchers - it's in the freezing waters of southern Greenland.
The reef is comprised of what are called living cold-water corals and while there are several species of coral in Greenland, this is the first time that an actual reef has been found.

The newly discovered living reef is located off Cape Desolation, south of Ivittuut, and lies at a depth of 984 yards (900 metres) in a spot with very strong currents, making it difficult to reach.
This also means that so far little is known about the reef itself and what lives on it.
 The reef was discovered by accident when a Canadian research vessel needed to take some water samples. When the ship sent the measuring instruments down to the depths, they came back up completely smashed.
