How BP Gulf disaster may have triggered a 'world-killing' event

doom in the gulfOminous reports are leaking past the BP Gulf salvage operation news blackout that the disaster unfolding in the Gulf of Mexico may be about to reach biblical proportions.

251 million years ago a mammoth undersea methane bubble caused massive explosions, poisoned the atmosphere and destroyed more than 96 percent of all life on Earth. Experts agree that what is known as the Permian extinction event was the greatest mass extinction event in the history of the world.

55 million years later another methane bubble ruptured causing more mass extinctions during the Late Paleocene Thermal Maximum (LPTM). The LPTM lasted 100,000 years.

Those subterranean seas of methane virtually reshaped the planet when they explosively blew from deep beneath the waters of what is today called the Gulf of Mexico. Now, worried scientists are increasingly concerned the same series of catastrophic events that led to worldwide death back then may bThose subterranean seas of methane virtually reshaped the planet when they explosively blew from deep beneath the waters of what is today called the Gulf of Mexico.

Now, worried scientists are increasingly concerned the same series of catastrophic events that led to worldwide death back then may be happening again-and no known technology can stop it. More

500 African penguins killed by big freeze in South Africa

Global warming would be welcome for freezing penguins - photo by Rockbobster Nearly 500 rare African penguins have died in the past 24 hours as a result of extremely cold weather in South Africa’s Eastern Cape province.

An AFP report quoted a national parks agency spokesperson, Megan Taplin, who said: "The chicks, aged between a few weeks old and about two months old and covered only with down feathers, succumbed to the cold and wet weather which has hit Bird Island."

The report said the penguin population was already dwindling with only 700 breeding pairs left in the area.

The African Penguin (Spheniscus demersus),is also known as the Black-Footed penguin or the Jackass penguin because of its braying call. The species was officially renamed “African” penguin as it is the only penguin species that breeds on the African continent. It has distinctive black and white markings, with a black stripe and spots on the chest, which are unique to each bird. More

Man killed by swarm of bees

bees swarm and kill a man A 54-year-old man was killed Wednesday morning by a swarm of bees in a remote area of Encinitas, a fire official said.

The man was working outdoors with his nephew, clearing the property at about 11 a.m., when the backhoe he was driving disturbed a colony of bees, said Encinitas fire Deputy Chief Scott Henry.

Firefighters arrived to find the man had taken shelter in an outhouse about 200 yards from the colony.

"He was covered in bee stings and in full cardiac arrest," Henry said.

The man was rushed to the hospital, where he later died. It was unclear late Wednesday whether the man was allergic to bee stings. More

Scientist: Global Cooling is the Real Crisis

Global warming conference participant says reduced sunspot activity may cause extreme cold fatalities, mass starvation Most of us have heard or seen what global warming alarmists say the consequences will be if something isn’t done to limit the man’s impact on the environment. Al Gore, in his movie “An Inconvenient Truth,” warns global sea levels will rise by a whopping 20 feet, causing coastal flooding and creating a refugee crisis. Others aren’t quite as gloomy, but that’s not the real threat to the planet.

At the Heartland Institute’s International Conference on Climate Change on May 17, Professor Don Easterbrook of Western Washington University warned that the climate is headed for a period of cooling. He told the Chicago gathering of hundreds of scientists and policy professionals that there are three possibilities of cooling, examples of which we’ve seen within the last 200 years. More

As Global Temperatures Rise, World's Lizards Are Disappearing

Madagascar is a hotspot of extinctions - lizards For many lizards, global climate change is a matter of life and death. After decades of surveying Sceloporus lizard populations in Mexico, an international research team has found that rising temperatures have driven 12 percent of the country's lizard populations to extinction. An extinction model based on this discovery also forecasts a grim future for these ecologically important critters, predicting that a full 20 percent of all lizard species could be extinct by the year 2080.

The detailed surveys of lizard populations in Mexico, collected from 200 different sites, indicate that the temperatures in those regions have changed too rapidly for the lizards to keep pace. It seems that all types of lizards are far more susceptible to climate-warming extinction than previously thought because many species are already living right at the edge of their thermal limits, especially at low elevation and low latitude range limits.

Growing low-oxygen zones in oceans worry scientists

oceans doomed for lack of oxygen Lower levels of oxygen in the Earth's oceans, particularly off the United States' Pacific Northwest coast, could be another sign of fundamental changes linked to global climate change, scientists say.

They warn that the oceans' complex undersea ecosystems and fragile food chains could be disrupted.

In some spots off Washington state and Oregon , the almost complete absence of oxygen has left piles of Dungeness crab carcasses littering the ocean floor, killed off 25-year-old sea stars, crippled colonies of sea anemones and produced mats of potentially noxious bacteria that thrive in such conditions.

Areas of hypoxia, or low oxygen, have long existed in the deep ocean. These areas — in the Pacific, Atlantic and Indian oceans — appear to be spreading, however, covering more square miles, creeping toward the surface and in some places, such as the Pacific Northwest , encroaching on the continental shelf within sight of the coastline.

Bees in more trouble than ever after bad winter

where's the bees? The mysterious 4-year-old crisis of disappearing honeybees is deepening. A quick federal survey indicates a heavy bee die-off this winter, while a new study shows honeybees' pollen and hives laden with pesticides.

Two federal agencies along with regulators in California and Canada are scrambling to figure out what is behind this relatively recent threat, ordering new research on pesticides used in fields and orchards. Federal courts are even weighing in this month, ruling that the U.S. Environmental Protection Agency overlooked a requirement when allowing a pesticide on the market.

And on Thursday, chemists at a scientific conference in San Francisco will tackle the issue of chemicals and dwindling bees in response to the new study.

Scientists are concerned because of the vital role bees play in our food supply. About one-third of the human diet is from plants that require pollination from honeybees, which means everything from apples to zucchini. More

Climatologists Baffled by Global Warming Time-Out

burn baby burn Global warming appears to have stalled. Climatologists are puzzled as to why average global temperatures have stopped rising over the last 10 years. Some attribute the trend to a lack of sunspots, while others explain it through ocean currents.

At least the weather in Copenhagen is likely to be cooperating. The Danish Meteorological Institute predicts that temperatures in December, when the city will host the United Nations Climate Change Conference, will be one degree above the long-term average.

Otherwise, however, not much is happening with global warming at the moment. The Earth's average temperatures have stopped climbing since the beginning of the millennium, and it even looks as though global warming could come to a standstill this year. More

Urban 'Green' Spaces May Contribute to Global Warming

The green green grass of doom Dispelling the notion that urban "green" spaces help counteract greenhouse gas emissions, new research has found -- in Southern California at least -- that total emissions would be lower if lawns did not exist.

Turfgrass lawns help remove carbon dioxide from the atmosphere through photosynthesis and store it as organic carbon in soil, making them important "carbon sinks." However, greenhouse gas emissions from fertilizer production, mowing, leaf blowing and other lawnmanagement practices are four times greater than the amount of carbon stored by ornamental grass in parks, a UC Irvine study shows. These emissions include nitrous oxide released from soil after fertilization. Nitrous oxide is a greenhouse gas that's 300 times more powerful than carbon dioxide, the Earth's most problematic climate warmer. More

We'd best mark apocalyptic predictions for 2012 in pencil

The end of days is near - maybe The world did not end as the clock ticked ominously past midnight and into the wee hours of January 1, 2000.

Computers and their networks did not crash. Satellites did not fall from the sky. Power grids did not wink out. We were not thrust into a dark, cold and medieval existence.

Humanity carried on as usual after Y2K, happily reproducing, polluting and pillaging land and sea. But human beings, it seems, can't shake a deep feeling of impending doom, even in happy times.

We survived Y2K. Now we've got the next curtain call for civilization -- December 21, 2012. That's right, citizens, there are less than 1,100 shopping days until the end of days. More

Peru's mountain people fight for surviving a bitter winter

A farmer walks with her son during a potato harvest in Huancavelica, southern Peru For alpaca farmer Ignacio Beneto Huamani and his young family, life in the Peruvian Andes, at almost 4,700m above sea level, has always been a struggle against the elements. His village of Pichccahuasi, in Peru's Huancavelica region, is little more than a collection of small thatched shelters and herds of alpaca surrounded by beautiful, yet bleakly inhospitable, mountain terrain.

The few hundred people who live here are hardened to poverty and months of sub-zero temperatures during the long winter. But, for the fourth year running, the cold came early. First their animals and now their children are dying and in such escalating numbers that many fear that life in the village may be rapidly approaching an end.

In a world growing ever hotter, Huancavelica is an anomaly. These communities, living at the edge of what is possible, face extinction because of increasingly cold conditions in their own microclimate, which may have been altered by the rapid melting of the glaciers. More

Western Reservoirs Could Be Dry By 2050

The Colorado River is among rivers worldwide that have been affected by a warming Earth. There's a one-in-two chance that the water reservoirs of the Colorado River will dry up by 2050 if water management practices remain unchanged in our warming world, a new study finds.

Roughly 30 million people — including many in Arizona and Southern California — depend on the Colorado River for drinking and irrigation water.

The Colorado River system is enduring its 10th year of drought, with the reservoir system currently at 59 percent of capacity, about the same as this time last year.

Previous studies have warned of the potential for water shortages with the drier conditions in the West brought about by climate change. The region's growing population has also put pressure on the water supplies of the desert West. More

Record cold weather dominates large areas

The Colorado River is among rivers worldwide that have been affected by a warming Earth. As Britain struggles to cope with a few inches of snow, spare a thought for the travellers who were trapped on this train in Mongolia.

Snow drifts several metres deep meant an army of rescue workers had to be sent out to free the passengers from their carriages.

Heavy snow and unusually harsh winter weather snarled up transport across India, northern China and South Korea.

Major roads in Beijing and Tianjin, as well as nearby provinces Hebei, Shanxi and Inner Mongolia, were forced to close due to the heavy snow. The snow shows no sign of stopping, however, and temperatures are expected to drop to -16C in Beijing today, causing more problems for those attempting to return to work after a three-day New Year holiday.

Climate change alliance crumbling

work by street artist Banksy with the words 'I DON'T BELIEVE IN GLOBAL WARMING' Cracks emerged on Tuesday in the alliance on climate change formed at the Copenhagen conference last week, with leading developing countries criticising the resulting accord.

The so-called Basic countries – Brazil, South Africa, India and China – backed the accord in a meeting with the US on Friday night, and it was also supported by almost all other nations at the talks, including all of the biggest emitters.

But on Tuesday the Brazilian government labelled the accord “disappointing” and complained that the financial assistance it contained from rich to poor countries was insufficient.

South Africa also raised objections: Buyelwa Sonjica, the environment minister, called the failure to produce a legally binding agreement “unacceptable”. She said her government had considered leaving the meeting.

“We are not defending this, as I have indicated, for us it is not acceptable, it is definitely not acceptable,” she said. More

Climate change 'sceptic' Ian Plimer argues CO2 is not causing global warming

Carbon dioxide in the atmosphere is a natural phenomenon caused by volcanoes and is not responsible for climate change Professor Ian Plimer, a geologist from Adelaide University, argues that a recent rise in temperature around the world is caused by solar cycles and other "extra terrestrial" forces.

He said carbon dioxide in the atmosphere, widely blamed for global warming, is a natural phenomenon caused by volcanoes erupting.

"We cannot stop carbon emissions because most of them come from volcanoes," he said. "It is a normal element cycled around in the earth and my science, which is looking back in time, is saying we have had a planet that has been a green, warm wet planet 80 per cent of the time. We have had huge climate change in the past and to think the very slight variations we measure today are the result of our life - we really have to put ice blocks in our drinks." More

Obama’s Science Czar John Holdren involved in unwinding “Climategate” scandal

ohn Holdren is hip deep in global warming fraud Lift up a rock and another snake comes slithering out from the ongoing University of East Anglia Climate Research Unit (CRU) scandal, now riding as “Climategate”.

Obama Science Czar John Holdren is directly involved in CRU’s unfolding Climategate scandal.

In fact, according to files released by a CEU hacker or whistleblower, Holdren is involved in what Canada Free Press (CFP) columnist Canadian climatologist Dr. Tim Ball terms “a truculent and nasty manner that provides a brief demonstration of his lack of understanding, commitment on faith and willingness to ridicule and bully people”.

“The files contain so much material that it is going to take some time t o put it all in context,” says Ball. “However, enough is already known to underscore their explosive nature. It is already clear the entire claims and positions of the Intergovernmental Panel on Climate Change (IPCC) are based on falsified manipulated material and is therefore completely compromised. More

Gropenhagen Conference: Prostitutes Offer Free Climate Summit Sex

Carbon dioxide in the atmosphere is a natural phenomenon caused by volcanoes and is not responsible for climate change Copenhagen's city council in conjunction with Lord Mayor Ritt Bjerregaard sent postcards out to 160 Copenhagen hotels urging COP15 guests and delegates to 'Be sustainable - don't buy sex'.

"Dear hotel owner, we would like to urge you not to arrange contacts between hotel guests and prostitutes," the approach to hotels says.

Now, Copenhagen prostitutes are up in arms, saying that the council has no business meddling in their affairs. They have now offered free sex to anyone who can produce one of the offending postcards and their COP15 identity card, according to the Web site avisen.dk. More

ClimateGate - Climate center's server hacked revealing documents and emails

global warming fraud exposed - epic FAIL Britain’s Climate Research Unit, University of East Anglia, suffered a data breach in recent days when a hacker apparently broke into their system and made away with thousands of emails and documents. The stolen data was then posted to a Russian server and has quickly made the rounds among climate skeptics. The documents within the archive, if proven to be authentic, would at best be embarrassing for many prominent climate researchers and at worst, damning.

The electronic break in itself has been verified by the director of the research unit, Professor Phil Jones. He told Britain’s Investigate magazine's TGIF Edition "It was a hacker. We were aware of this about three or four days ago that someone had hacked into our system and taken and copied loads of data files and emails." More

Cattle be £75 for each farting cow

environmental fundamentalists run amuck SCOTS farmers’ leaders were fuming last night over barmy EU plans to combat climate change — with a tax on cows’ FARTS.

Member states are considering the bizarre flatulence tariff of £75 per beast in a bid to bring gas emissions in line with Brussels rules.

Figures show that a single cow can emit up to four tons of methane a year by breaking wind. And the farts and burps of farm livestock are estimated to make up 18 per cent of all greenhouse gas discharges.

But Scots Tory MEP Struan Stevenson last night urged ministers to to resist the moves as farmers feel the pinch in the recession. He said: “It would be a catastrophic mistake. The Danish government is said to be considering a staggering £75 per cow tax. More

CO2 Levels Were This High 15 Million Years Ago

Levels of carbon dioxide have varied only between 180 and 300 parts per million over the last 800,000 years You would have to go back at least 15 million years to find carbon dioxide levels on Earth as high as they are today, a UCLA scientist and colleagues report in the online edition of the journal Science.

"The last time carbon dioxide levels were apparently as high as they are today — and were sustained at those levels — global temperatures were 5 to 10 degrees Fahrenheit higher than they are today, the sea level was approximately 75 to 120 feet higher than today, there was no permanent sea ice cap in the Arctic and very little ice on Antarctica and Greenland," said the paper's lead author, Aradhna Tripati, a UCLA assistant professor in the department of Earth and space sciences and the department of atmospheric and oceanic sciences.

"Carbon dioxide is a potent greenhouse gas, and geological observations that we now have for the last 20 million years lend strong support to the idea that carbon dioxide is an important agent for driving climate change throughout Earth's history," she said. More

Beetle attack will change our world

Pine beetles are nothing new, they are part of the forest eco-system, but warmer winters and a drier weather has created perfect growing conditions for the beetle. Slash piles surround the parking area on Pelton Creek Road in the Medicine Bow National Forest, southwest of Laramie near the Colorado border.

Grant Frost, a terrestrial habitat biologist for Wyoming Game and Fish, inspects a tree, looking for tell-tale signs of beetles.

The tree looks alive, but it probably won't be for long. The brown cadavers of lodgepoles past stand among smaller, greener pines, testifying to the unavoidable truth: Change -- big change -- is coming.

"The general feeling is this will end when the food supply runs out," Frost says. More

2012 isn't the end of the world, Mayans insist

Guatemalan Mayan Indian elder Apolinario Chile Pixtun MEXICO CITY – Apolinario Chile Pixtun is tired of being bombarded with frantic questions about the Mayan calendar supposedly "running out" on Dec. 21, 2012. After all, it's not the end of the world.

Or is it?

Definitely not, the Mayan Indian elder insists. "I came back from England last year and, man, they had me fed up with this stuff."

It can only get worse for him. Next month Hollywood's "2012" opens in cinemas, featuring earthquakes, meteor showers and a tsunami dumping an aircraft carrier on the White House.

At Cornell University, Ann Martin, who runs the "Curious? Ask an Astronomer" Web site, says people are scared.

"It's too bad that we're getting e-mails from fourth-graders who are saying that they're too young to die," Martin said. "We had a mother of two young children who was afraid she wouldn't live to see them grow up." More

Antarctic ice is growing, not melting away

freezing over ICE is expanding in much of Antarctica, contrary to the widespread public belief that global warming is melting the continental ice cap.

The results of ice-core drilling and sea ice monitoring indicate there is no large-scale melting of ice over most of Antarctica, although experts are concerned at ice losses on the continent's western coast.

Antarctica has 90 per cent of the Earth's ice and 80 per cent of its fresh water, The Australian reports. Extensive melting of Antarctic ice sheets would be required to raise sea levels substantially, and ice is melting in parts of west Antarctica. The destabilisation of the Wilkins ice shelf generated international headlines this month. More

Vaster Regions of Antarctica Melting Into Sea

slosh, all that ice melts into the sea Antarctic glaciers are melting faster across a much wider area than previously thought, scientists said Wednesday -- a development that could lead to an unprecedented rise in sea levels.

A report by thousands of scientists for the 2007-2008 International Polar Year concluded that the western part of the continent is warming up, not just the Antarctic Peninsula.

Previously most of the warming was thought to occur on the narrow stretch pointing toward South America, said Colin Summerhayes, executive director of the Britain-based Scientific Committee on Antarctic Research and a member of International Polar Year's steering committee.

But satellite data and automated weather stations indicate otherwise. More

Sydney turns red: dust storm blankets city

Sydney Harbour Bridge in red Sydneysiders have woken to a red haze unlike anything seen before by residents or weather experts, as the sun struggles to pierce a thick blanket of dust cloaking the city this morning.

Callers flooded talkback radio, others hit social networking sites and scores of emails were received from smh.com.au readers as Sydney residents expressed their amazement at this morning's conditions.

"It's just red, red, red as far as you can see," one caller at the Anzac Bridge told 2GB. More

Chemicals That Eased One Woe Worsen Another

panic! now! This is not the funny kind of irony: Scientists say the chemicals that helped solve the last global environmental crisis -- the hole in the ozone layer -- are making the current one worse.

The chemicals, called hydrofluorocarbons (HFCs), were introduced widely in the 1990s to replace ozone-depleting gases used in air conditioners, refrigerators and insulating foam. They worked: The earth's protective shield seems to be recovering.

But researchers say what's good for ozone is bad for climate change. In the atmosphere, these replacement chemicals act like "super" greenhouse gases, with a heat-trapping power that can be 4,470 times that of carbon dioxide. More

Scientists predict greater longevity for planets with life

earth in the balance Roughly a billion years from now, the ever-increasing radiation from the sun will have heated Earth into inhabitability; the carbon dioxide in the atmosphere that serves as food for plant life will disappear, pulled out by the weathering of rocks; the oceans will evaporate; and all living things will disappear.

Or maybe not quite so soon, say researchers from the California Institute of Technology (Caltech), who have come up with a mechanism that doubles the future lifespan of the biosphere—while also increasing the chance that advanced life will be found elsewhere in the universe.

A paper describing their hypothesis was published June 1 in the early online edition of the Proceedings of the National Academy of Sciences (PNAS). More

Quake, tsunami potential high on U.S. west coast

earth in the balance WASHINGTON - Scientists have underestimated the potential for a giant quake and tsunami that could swamp much the U.S. northwest and Canadian west coasts, British and U.S. researchers said on Monday.

Geological evidence suggests there have been earthquakes in the past that were even stronger than a magnitude 9.2 quake -- the second-biggest ever recorded -- which caused a 42-foot-high (12-meter-high) tsunami in the Gulf of Alaska in 1964, they said.

"Our data indicate that two major earthquakes have struck Alaska in the last 1,500 years and our findings show that a bigger earthquake and a more destructive tsunami than the 1964 event are possible in the future," Ian Shennan, a professor of geography at Britain's Durham University, who led the study, said in a statement. More

El Nino an early warning for food security

El Niño brings the prospect of another drought JOHANNESBURG - Rising sea surface temperatures across the central and eastern Pacific Ocean herald El Niño, which could disrupt the rains in major cereal producing regions, the World Meteorological Organization (WMO) has warned.

"Typically, an El Niño has the potential to disrupt the rainy seasons and cause lower rainfall in India, Australia, Southeast Asia - Philippines and Indonesia - southern Africa and Central America," said Robert Stefanski, a WMO scientific officer who works on agriculture-related weather and climate issues.

"In past El Niño events, there was lowered food production in many of these regions." More

MIT Model Predicts Accelerating Warming Trends

now we roast If an unusually detailed computer simulation at the Massachusetts Institute of Technology has it right, global warming in this century is on track to be about twice as bad as predicted six years ago.

The MIT model is said to be the only one that incorporates among its variables possible changes in economic growth and other human activities and draws on peer-reviewed science on the climatic effects of atmospheric, oceanic and biological systems.

After running the model 400 times with slight variations in the inputs, the new predictions are for surface temperatures to warm by 6.3 to 13.3 degrees Fahrenheit. The prediction is for a 9.4-degree increase in the median temperature, more than double the 4.3 degrees predicted in a 2003 simulation. More

Not so windy: Research suggests winds dying down

so much for wind power The wind, a favorite power source of the green energy movement, seems to be dying down across the United States. And the cause, ironically, may be global warming - the very problem wind power seeks to address.

The idea that winds may be slowing is still a speculative one, and scientists disagree whether that is happening. But a first-of-its-kind study suggests that average and peak wind speeds have been noticeably slowing since 1973, especially in the Midwest and the East.

"It's a very large effect," said study co-author Eugene Takle, a professor of atmospheric science at Iowa State University. In some places in the Midwest, the trend shows a 10 percent drop or more over a decade. More

New Zealand could go bust over Global Warming

global warming a bust for New Zealand No country in the world would risk as much for “global warming” as New Zealand if it goes ahead with the cap-and-trade energy taxation installed by Helen Clarke’s now-departed Labour Government.

New Zealand’s economy is almost completely dependent on its farm exports: lamb, dairy products, beef and high-end white wines. Half of New Zealand’s carbon emissions come from cattle and sheep. If New Zealand taxes its cows and sheep hundreds of dollars per animal for methane emissions and manure handling fees, Argentina would almost immediately displace New Zealand’s farm exports. Argentina has more grass, more cattle, the potential for more lambs, a surging wine industry—and no Kyoto obligations. More

The missing sunspots: Is this the big chill?

The disappearance of sunspots happens every few years Could the Sun play a greater role in recent climate change than has been believed? Climatologists had dismissed the idea and some solar scientists have been reticent about it because of its connections with those who those who deny climate change. But now the speculation has grown louder because of what is happening to our Sun. No living scientist has seen it behave this way. There are no sunspots.

The disappearance of sunspots happens every few years, but this time it’s gone on far longer than anyone expected – and there is no sign of the Sun waking up. “This is the lowest we’ve ever seen. We thought we’d be out of it by now, but we’re not,” says Marc Hairston of the University of Texas. More

Bacteria Create Aquatic Superbugs In Waste Treatment Plants

bacteria in wastewater treatment plants For bacteria in wastewater treatment plants, the stars align perfectly to create a hedonistic mating ground for antibiotic-resistant superbugs eventually discharged into streams and lakes.

In the first known study of its kind, Chuanwu Xi of the University of Michigan School of Public Health and his team sampled water containing the bacteria Acinetobacter at five sites in and near Ann Arbor's wastewater treatment plant.

They found the so-called superbugs—bacteria resistant to multiple antibiotics—up to 100 yards downstream from the discharge point into the Huron River. Xi stresses that while the finding may be disturbing, it is important to understand that much work is still needed to assess what risk, if any, the presence of superbugs in aquatic environments poses to humans.

Caps, Trades and Offsets: Can Climate Plan Work?

brother can you spare some carbon? It sounds like alchemy, an act of bureaucratic magic. Under the climate-change bill just approved by a House committee, the U.S. government would literally make a commodity -- as tradable as a Pontiac or a pork belly -- out of thin air.

The bill would require polluters to obtain "allowances" -- permits allowing them to emit a given amount of a greenhouse gas such as carbon dioxide or methane. Today, these gases are invisible, free and floating all around us. This bill would put a price on them.

That would accomplish an economist's version of a triple back flip. It would divide a problem of the global commons into pieces and make those who use gas or electricity pay for their share of the emissions that result. More

Honeybee Numbers Expand Worldwide as U.S. Decline Continues

The domestic honeybee is enjoying a global population boom even as colony collapse disorder threatens them in the U.S. and Europe. Even as U.S. honeybee populations have been hit hard by colony collapse disorder in recent years, domesticated beehives have been thriving elsewhere.

In an analysis of nearly 50 years of data on bees from the United Nations Food and Agriculture Organization, researchers found that domesticated honeybee populations have increased about 45 percent, thanks in large part to expansion of the bees into areas such as South America, eastern Asia and Africa. The results appear in the latest issue Current Biology.

The overall increase, however, is not what surprised Marcelo Aizen, a professor at the National University of Comahue in Buenos Aires, Argentina, and lead author of the study. Instead, he was taken aback by the sixfold increase in the growth rate of crops that depend on domesticated bees for pollination. More

Next Panic: Carbonated oceans

loading of carbon dioxide into oceans Like a sinkful of hard water deposits suddenly doused with vinegar, the shells of tiny marine snails in Victoria Fabry's test tanks don't stand a chance.

Fabry, a biological oceanographer and visiting researcher at Scripps Institution of Oceanography at UC San Diego, studies the effects of ocean acidification on the molluscs known as pteropods. In one experiment, only 48 hours of exposure to slightly corrosive seawater caused normally smooth shells to become frayed at the edges on their way to eventual dissolution, severely diminishing their owners' chances of survival.

The acidity of the water in Fabry's lab had been ratcheted up to levels that might not be seen until the end of the century, but she and other scientists fear that ongoing acidification of ocean water could be causing a slow-motion destruction of ocean ecosystems now. More

Climate change means bigger medical bills

getting toasty in here Climate change concerns like melting icecaps, increased desertification, loss of coral reefs and the extinction of species like polar bears can seem a distant concern in our everyday lives. Little attention, however, has been paid to the likelihood of increased bills, through tax and insurance charges, that will be incurred as the UK climate changes.

Alistair Hunt, a researcher at the University of Bath, will be addressing scientists this week at the international Climate Change Congress being held in Copenhagen to present research which shows that the cost of climate change is going to be felt much closer to home than many expect. Alistair’s talk is one of many described in the complete online abstract book of the congress, published in the IOP Conference Series: Earth and Environmental Science. More

Blue Sky Research: Increase in Global Air Pollution

gasp choke on foul air A University of Maryland-led team has compiled the first decades-long database of aerosol measurements over land, making possible new research into how air pollution affects climate change.

Using this new database, the researchers show that clear sky visibility over land has decreased globally over the past 30 years, indicative of increases in aerosols, or airborne pollution.

“Creation of this database is a big step forward for researching long-term changes in air pollution and correlating these with climate change,” said Kaicun Wang, assistant research scientist in the University of Maryland’s department of geography and lead author of the paper. More

Global Warming: On Hold?

Warming, What Warming? For those who have endured this winter's frigid temperatures and today's heavy snowstorm in the Northeast, the concept of global warming may seem, well, almost wishful.

But climate is known to be variable -- a cold winter, or a few strung together doesn't mean the planet is cooling. Still, according to a new study in Geophysical Research Letters, global warming may have hit a speed bump and could go into hiding for decades.

Earth's climate continues to confound scientists. Following a 30-year trend of warming, global temperatures have flatlined since 2001 despite rising greenhouse gas concentrations, and a heat surplus that should have cranked up the planetary thermostat. More

Mr Whipple: An Eco-terrorist?

Mr Whipple an eco terrorist? But  not gay. Americans like their toilet tissue soft: exotic confections that are silken, thick and hot-air-fluffed.

The national obsession with soft paper has driven the growth of brands like Cottonelle Ultra, Quilted Northern Ultra and Charmin Ultra — which in 2008 alone increased its sales by 40 percent in some markets, according to Information Resources, Inc., a marketing research firm.

But fluffiness comes at a price: millions of trees harvested in North America and in Latin American countries, including some percentage of trees from rare old-growth forests in Canada. Although toilet tissue can be made at similar cost from recycled material, it is the fiber taken from standing trees that help give it that plush feel, and most large manufacturers rely on them.

Ecosystems Push South in Antarctica

Adelie Penguins on Dream Island Adelie penguins are flocking closer to the South Pole. A new study in the leading journal Science explains why: they're following the food supply, which is moving southward with changing climate.

Krill, the shrimp-like critters that Adelies like to eat, feed on phytoplankton. But as global temperatures rise, phytoplankton are declining in the north while increasing further south. The poleward shift is taking place on the Western Antarctic Peninsula, a finger of land stretching toward South America, one of the fastest warming places on Earth. For decades, penguins and other Antarctic predators have been observed further south on the peninsula, where temperatures are colder and sea ice more plentiful. Previous research shows that Adélie penguins have decreased 70 to 80 percent over their northern range. More

Climate Fears Are Driving 'Ecomigration' Across Globe

Adam Fier, wife Misbah Sadat and daughters Maya and Maha moved to New Zealand partly out of climate concerns. Adam Fier recently sold his home, got rid of his car and pulled his twin 6-year-old girls out of elementary school in Montgomery County. He and his wife packed the family's belongings and moved to New Zealand -- a place they had never visited or seen before, and where they have no family or professional connections. Among the top reasons: global warming.

Halfway around the world, the president of Kiribati, a Pacific nation of low-lying islands, said last week that his country is exploring ways to move all its 100,000 citizens to a new homeland because of fears that a steadily rising ocean will make the islands uninhabitable. The two men are at contrasting poles of a phenomenon that threatens to reshape economies, politics and cultures across the planet. By choice or necessity, millions of "ecomigrants" -- most of them poor and desperate -- are on the move in search of more habitable living space. More

'Unprecedented' fires 'caused by climate change'

high levels of greenhouse gases Climate change experts have warned that severe weather events are likely to occur more often in Australia as global warming continues. Commenting on the Victorian bushfires, climatologist Professor David Karoly told the ABC's Lateline program on Monday night that hot temperatures in Melbourne on Saturday and in many parts of southeastern Australia were "unprecedented".

"The records were broken by a large amount and you cannot explain that just by natural variability," he said. "What we are seeing now is that the chances of these sorts of extreme fire weather situations are occurring much more rapidly in the last ten years due to climate change." More

Tree deaths soar in Western U.S.

Climate change is not just affecting the ice cover of the Arctic Ocean — it's closer to home Tree deaths, spurred by global warming, have more than doubled in older forests across Western states, federal scientists reported Thursday.

Droughts and pests brought on by warmer temperatures have killed firs, hemlocks, pines and other large trees in particular over the past 30 years without allowing replacements to sprout, the study published in the journal Science finds.

"Very likely the mortality rate will continue to rise," says lead author Phillip van Mantgem of the U.S. Geologic Survey. More

Antarctica Warming More Than Previously Thought

warming that scientists have determined has occurred in West Antarctica during the last 50 years Scientists studying climate change have long believed that while most of the rest of the globe has been getting steadily warmer, a large part of Antarctica – the East Antarctic Ice Sheet – has actually been getting colder.

But new research shows that for the last 50 years, much of Antarctica has been warming at a rate comparable to the rest of the world. In fact, the warming in West Antarctica is greater than the cooling in East Antarctica, meaning that on average the continent has gotten warmer, said Eric Steig, a University of Washington professor of Earth and space sciences and director of the Quaternary Research Center at the UW.

Earth on the Brink of an Ice Age

Earth on the Brink of an Ice Age The earth is now on the brink of entering another Ice Age, according to a large and compelling body of evidence from within the field of climate science. Many sources of data which provide our knowledge base of long-term climate change indicate that the warm, twelve thousand year-long Holocene period will rather soon be coming to an end, and then the earth will return to Ice Age conditions for the next 100,000 years.

Ice cores, ocean sediment cores, the geologic record, and studies of ancient plant and animal populations all demonstrate a regular cyclic pattern of Ice Age glacial maximums which each last about 100,000 years, separated by intervening warm interglacials, each lasting about 12,000 years. More

Drought, beetles killing forests

Thousands of oaks in East County have been ravaged by a beetle called the gold-spotted oak borer Bugs and diseases are killing trees at an alarming rate across the West, from the spruce forests of Alaska to the oak woodlands near the San Diego-Tijuana border.

Several scientists said the growing threat appears linked to global warming. That means tree mortality is likely to rise in places as the continent warms, potentially altering landscapes in ways that increase erosion, fan wildfires and diminish the biodiversity of Western forests.

It also could prompt new approaches to forestry. Possibilities include replanting logged areas with trees that are tolerant of higher temperatures, thinning drought-stressed forests and deploying pesticides to ward off insects.

But in many cases, landowners have few options to protect their trees once insects and diseases take hold, tree experts said. More

Climate Change Wiped Out Cave Bears 13 Millennia Earlier Than Thought

Cave bears were heavily built animals, with males growing up to around 1000kg. Enormous cave bears, Ursus spelaeus, that once inhabited a large swathe of Europe, from Spain to the Urals, died out 27,800 years ago, around 13 millennia earlier than was previously believed, scientists have reported.

The new date coincides with a period of significant climate change, known as the Last Glacial Maximum, when a marked cooling in temperature resulted in the reduction or loss of vegetation forming the main component of the cave bears' diet.

In a study published in Boreas, researchers suggest it was this deterioration in food supply that led to the extinction of the cave bear, one of a group of 'megafauna' - including woolly mammoth, woolly rhinoceros, giant deer and cave lion - to disappear during the last Ice Age. More

Sea levels set to rise faster than expected

The planet is now facing a new quality of change Geneva, Switzerland: Even warming of less than 2°C might be enough to trigger the loss of Arctic sea ice and the meltdown of the Greenland Ice Sheet, causing global sea levels to rise by several metres.

Ahead of next week’s meeting of governments in Poznan, Poland for UN climate talks WWF analysis of the latest climate science comes to the dire conclusion that humanity is approaching the last chance to keep global warming below the danger threshold of 2°C.

”The latest science confirms that we are now seeing devastating consequences of warming that were not expected to hit for decades,” said Kim Carstensen, WWF Global Climate Initiative leader. More

Revealed: the environmental impact of Google searches

is Google use green?Performing two Google searches from a desktop computer can generate about the same amount of carbon dioxide as boiling a kettle for a cup of tea, according to new research.

While millions of people tap into Google without considering the environment, a typical search generates about 7g of CO2 Boiling a kettle generates about 15g. “Google operates huge data centres around the world that consume a great deal of power,” said Alex Wissner-Gross, a Harvard University physicist whose research on the environmental impact of computing is due out soon. “A Google search has a definite environmental impact.” More

Climate change pushing lemmings over the edge

Once famous for their numbers, Norwegian lemmings are disappearing Once famous for their numbers, Norwegian lemmings are disappearing, say scientists, who point an accusing finger at global warming.

The hamster-like rodents burst forth in massive numbers from their sub-Arctic homes every three to five years in a frantic search for food. The mad dash sometimes causes them to race over clifftops and plummet into the sea, thus giving rise to the theory -- now discounted -- of mass suicide.

Since 1994, these periodic population explosions have stopped, prompting researchers to ask why. In a study published on Thursday, investigators say the blame lies not with too many predators or a fall in food supply, but changes in weather patterns. More

The methane time bomb

Preliminary findings suggest that massive deposits of subsea methane are bubbling to the surface as the Arctic region becomes warmer and its ice retreats The first evidence that millions of tons of a greenhouse gas 20 times more potent than carbon dioxide is being released into the atmosphere from beneath the Arctic seabed has been discovered by scientists.

Preliminary findings suggest that massive deposits of sub-sea methane are bubbling to the surface as the Arctic region becomes warmer and its ice retreats.

Underground stores of methane are important because scientists believe their sudden release has in the past been responsible for rapid increases in global temperatures, dramatic changes to the climate, and even the mass extinction of species. Scientists aboard a research ship that has sailed the entire length of Russia's northern coast have discovered intense concentrations of methane – sometimes at up to 100 times background levels – over several areas covering thousands of square miles of the Siberian continental shelf.

Climate change may drown cities

Sea level rise and surge-induced flooding threatens more than 3,000 cities JOHANNESBURG, SA - People in Dhaka, the capital of Bangladesh, prefer to commute in three-wheeled autorickshaws, taxis and buses that run on compressed natural gas (CNG), in their bid to slow down global warming.

CNG produces a lower level of greenhouse gases and is an environmentally cleaner alternative to petrol. Dhaka's residents are among the most vulnerable to global warming and don't want to become "climate terrorists".

The city is among more than 3,000 identified by the UN-Habitat's State of the World's Cities 2008/09 as facing the prospect of sea level rise and surge-induced flooding. The report warns policymakers, planners and the world at large that few coastal cities will be spared the effects of global warming. More
