blue-tongue moves north

A disease that normally only occurs in tropical or subtropical parts of the world made its first appearance in the UK last spring. It could be the first hard evidence that global warming is starting to change disease patterns around the world.

While this story carries an important message about human disease, this time at least, it was an animal disease that has moved. It’s the blue tongue virus, which affects cattle, sheep and goats.

It can be a devastating illness with up to a 70% mortality rate in sheep. The warmer temperatures have allowed blue tongue to gradually spread northwards in recent years, from Africa into southern Europe. That’s because the virus is carried by midges, which have headed north with the warmer weather.

But a shock came two years ago…blue tongue stopped following its well-predicted path and suddenly jumped into much colder northern Europe.

Professor Peter Mertens: An experienced veterinarian in Holland who saw a sick sheep and said: “Hey guys that looks like blue tongue to me, you know, out of the blue” and I imagine most people said “you’re kidding, it’s never been this far north”.

watch your step!

The country’s electricity and water supplies are at high risk from climate change, and immediate action is needed to prepare for the threat, a report presented to the Federal Government has warned.

Dams, roads, power stations and even paved footpaths are all at risk of damage from the increasing number of droughts and bushfires and rising sea levels during the next 30 to 50 years, said the report by the Australian Academy of Technological Sciences and Engineering.

“Adaptation to cope effectively with these situations is expected to require major investment with integrated, high-level strategic planning,” the report said.

Is that a pizzly or a grolar?

What is clear is that warming is increasing many opportunities for gene mixing.

“As we’ve developed genomic methodologies, we’re finding that organisms are exchanging genes with other species,” Michael Arnold, a professor of genetics at the University of Georgia, said.

“Genetic exchange due to organisms coming together from climate change is the rule rather than the exception.”

Animals have been interbreeding for millennia. Even modern humans are the product of genetic exchange with Neanderthals some 60,000 years ago.

But the rate at which species interbreed is accelerating because of climate change, researchers say. As habitats and animal ranges change and bleed into one another, species that never before would have encountered one another are now mating.

Warmer temperatures have allowed grizzly bears and polar bears to venture to habitats they don’t usually occupy and mate to form a hybrid: the pizzly or grolar bear.

saved by the Earth’s shift!

A new warning has come to NASA from the Inuits. They are warning that the change in climate is not due to global warming but rather, because of the Earth shifting a bit.

The Inuits are local people that live in the Arctic regions of Canada, the United States and Greenland. They are excellent weather forecasters and so were their ancestors. Presently they are warning NASA that the cause of change in weather, earthquakes etc, are not due to global warming as the world thinks.

They state that the earth has shifted or “wobbled”. “Their sky has changed!” The elders declare that the sun rises at a different position now, not where it used to previously. They also have longer daylight to hunt now, the sun is much higher than earlier, and it gets warmer much quickly.

Other elders across the north also confirmed the same thing about the sky changing when interviewed. They also alleged that the position of sun, moon and stars have all changed causing changes in the temperature. This has also affected the wind and it is very difficult to predict the weather now and according to them predicting weather is necessary on Arctic.

All the elders confirmed that the Earth has shifted, wobbled or tilted toward the North. This information provided by the Inuit Elders has caused a great concern in the NASA scientists. White Wolf Pack, 5 Mar 2004

all in a good cause

Sports fields, car parks and parklands will be important assets; houses will have walls that open, and some people might need to lose their water views to prepare for bigger, more frequent floods due to global warming, according to experts contacted by the Herald.

There is consensus in the scientific literature that “the flooding that happens on small urban type of catchments, which is a result of short rainfall bursts, is going up, because convection is intensifying”, Professor Ashish Sharma, an Australian Research Council future fellow in the school of civil and environmental engineering at the University of NSW, said.

that sinking feeling

Not only is the planet’s rising temperature melting massive glaciers, but it also seems to be thawing out the layer of permanently frozen soil below the ground’s surface. This thawing causes the ground to shrink and occurs unevenly, so it could lead to sinkholes and damage to structures such as railroad tracks, highways and houses.

fire and ice

Tropical forests may dry out and become vulnerable to devastating wildfires as global warming accelerates over the coming decades, a senior scientist has warned.

Soaring greenhouse gas emissions, driven by a surge in coal use in countries such as China and India, are threatening temperature rises that will turn damp and humid forests into parched tinderboxes, said Dr Chris Field, co-chair of the UN’s Nobel prize-winning Intergovernmental Panel on Climate Change (IPCC).

Higher temperatures could see wildfires raging through the tropics and a large scale melting of the Arctic tundra, releasing billions of tonnes of carbon into the atmosphere that will accelerate warming even further, he said.

moths go forth and…

Ecologist Florian Altermatt of the University of California, Davis has studied 44 species of moths and butterflies in Central Europe.

He published the results December 22 in the science journal, Proceedings of the Royal Society B article, “Climatic warming increases voltinism in European butterflies and moths” (which is available online for free for a few more days).

“Voltinism” refers to the number of breeding cycles in a year. As the region has warmed since the 1980s, some of these species have added an extra generation during the summer for the first time on record in that location.

Among the 263 species already known to have a second or third generation there during toasty times, 190 have grown more likely to do so since 1980. ThinkProgress, 26 Dec 2009

vote the rascals out!

Climate change is the most important social welfare issue we face as social workers. Unless we bring our best thinking and organizing to bear on climate change, our work on all the other issues near and dear to our hearts runs the risk of being comparable to rearranging deck chairs on the Titanic.

But individual actions are not enough. We need to be social worker activists, advocating to change public policies that will have major impact on the future we pass on to the next generation.

We can challenge elected officials at every level to support efforts to reduce the output of “greenhouse gases,” and we can vote the rascals out if they persist in wrong-headed decisions.

Saturn’s rings to solve global warming!

A wild idea to combat global warming suggests creating an artificial ring of small particles or spacecrafts around Earth to shade the tropics and moderate climate extremes.

There would be side effects, proponents admit. An effective sunlight-scattering particle ring would illuminate our night sky as much as the full Moon, for example.

But the idea, detailed today in the online version of the journal Acta Astronautica, illustrates that climate change can be battled with new technologies, according to one scientist not involved in the new work.

To keep the particles in place, gravitationally significant shepherding spacecraft might be employed. They would herd the particles much like small moons keep Saturn’s rings in place. LiveScience, 27 Jun 2005

live longer with climate change!

Actually, with respect to any temperature rise due to global warming, the research team found “For both men and women mortality was higher at low temperatures, suggesting a lesser ability to adapt to the cold.”

Based on another related study, they state “In England and Wales, the higher temperatures predicted for 2050 might result in nearly 9,000 fewer winter deaths each year.”

Laaidi et al. conclude “our findings give grounds for confidence in the near future: the relatively moderate (2°C) warming predicted to occur in the next half century would not increase annual mortality rates.”

surf’s up!

A team of geophysicists from the University of Victoria in British Columbia, Canada, have determined that gigantic ocean waves have been speeding up due to global warming.

These large ocean waves, known as planetary waves, typically span hundreds of kilometers from crest to crest.

Having predicted that planetary waves would accelerate as a result of the ocean surface warming, John Fyfe and Oleg Saenko, writing in the latest issue of Geophysical Research Letters, modeled the changes to ocean wave patterns over the 20th and 21st centuries to test their hypothesis.

“We knew we’d see an effect, but we didn’t think it would be significant for at least another two centuries,” Fyfe said. TreeHugger, 13 Jun 2007

last-ditch effort to halt global warming!

The US government wants the world’s scientists to develop technology to block sunlight as a last-ditch way to halt global warming, the Guardian has learned.

It says research into techniques such as giant mirrors in space or reflective dust pumped into the atmosphere would be “important insurance” against rising emissions, and has lobbied for such a strategy to be recommended by a major UN report on climate change, the first part of which will be published on Friday.

Scientists have previously estimated that reflecting less than 1% of sunlight back into space could compensate for the warming generated by all greenhouse gases emitted since the industrial revolution.

Possible techniques include putting a giant screen into orbit, thousands of tiny, shiny balloons, or microscopic sulphate droplets pumped into the high atmosphere to mimic the cooling effects of a volcanic eruption.

unprecedented sequence

What is clear, the scientists say, is that the floods in Pakistan – and the fires in Russia, the mudslides in China, the droughts in sub-Saharan Africa – are enunciations of scenarios climate forecasters have long predicted.

The “unprecedented sequence of extreme weather” over the past month matches climate projections, says the WMO. This is what global warming looks like, say climate experts at NASA. For years the warnings have been laid out in the scientific journals and in sober economic analyses. Global warming would super-saturate monsoons, extend droughts, breathe fury into wildfires and frenzy into hurricanes and cyclones.

Climate change raises fundamental questions of human security, survival and the stability of nation states, security expert Professor Alan Dupont argues. It will contribute to destabilising, unregulated population movements through Asia and the Pacific – mostly within borders, but the ripple effects will spill beyond them.

La Nina to double!

Extreme weather arising from a climate phenomenon in the Pacific Ocean will get much worse as the world warms, according to climate modelling.

The latest data – based on detailed climate modelling work – suggests extreme La Nina events in the Pacific Ocean will almost double with global warming, from one in 23 years to one in 13 years. Most will follow extreme El Nino events, meaning frequent swings between opposite extremes from one year to the next.

Prof Mat Collins, Joint Met Office Chair in Climate Change at Exeter University, UK, is a co-researcher on the study, which involved teams in Australia, China, the US, UK and Peru. He said scientists were getting a better idea of how El Nino and La Nina are affected by global warming.

“Our previous research showed a doubling in frequency of extreme El Nino events, and this new study shows a similar fate for the cold phase of the cycle,” he said. “It shows again how we are just beginning to understand the consequences of global warming.”

you take the high road …

The University of Durham looked at levels of land uplift and subsidence in the British isles since the Ice Age.

As the ice retreated 20,000 years ago the release of the enormous weight meant the north slowly tilted up while the south sank down. Scotland is still experiencing this “springboard” effect while southern Ireland, Wales and England continues to sink.

Prof Ian Shennan, who led the study, said soil sediments showed that sites in the north of the country are still rising.

“Subsidence and rising sea levels will have implications for people and habitats, and will require action to manage resorts, industrial sites, ports, beaches, salt marshes and wetlands, wildlife and bird migrations,” he said.

giant gun to solve global warming!

Scientists claim they can fight global warming by firing trillions of mirrors into space to deflect the sun’s rays forming a 100,000 square mile “sun shade”.

According to astronomer Dr Roger Angel, at the University of Arizona, the trillions of mirrors would have to be fired one million miles above the earth using a huge cannon with a barrel of 0.6 miles across. The gun would pack 100 times the power of conventional weapons and need an exclusion zone of several miles before being fired.

Dr Angel has already secured NASA funding for a pilot project and British inventor Tod Todeschini, 38, was commissioned to build a scaled-down version of the gun. He constructed the four-metre long cannon in his workshop in Sandlake, Oxfordshire, for a TV documentary investigating the sun shield theory.

He said: “The gun was horrendously dangerous. This was the first gun I’d ever built.”

wolves bridges burnt

For the gray wolves of Michigan’s Isle Royale National Park, climate change has turned their island home from a refuge of solitude into untenable isolation.

Wolves were first spotted on Isle Royale in 1948; they were likely attracted by the moose. But how did either species get out there in the first place? By way of ice bridges from the mainland to the island, said wildlife ecologist Rolf Peterson of Michigan Technological University.

But continued burning of fossil fuels has warmed winter temperatures in the region. Ice formation on Lake Superior has decreased, and ice bridges are becoming increasingly rare.

“In the ’60s, an ice bridge would form about four out of every five years; now, it’s more like one out of every 10 years,” Peterson said. takepart, 16 Mar 2016

all is lost-ski

Global warming will sow destruction across Russia and ex-Soviet states, a report said on Tuesday after the world’s richest countries issued targets on harmful emissions that environmentalists criticized as too soft.

The 52-page report — written by green group WWF and British charity Oxfam — described a grim picture of social, ecological and economic collapse in the world’s biggest country and its former empire unless the world took urgent action. This diagram shows infrastructure collapse.

When the temperature rises the infrastructure breaks, WWF climate change expert in Russia Alexei Kokorin said holding up a diagram of the ex-Soviet Union swathed in bands of red, orange and yellow at a presentation of the report in Moscow.

We must understand that damage caused by climate change is here and now rather than a problem in the distant future, in distant lands, WWF’s director in Russia, Igor Chestin, said in a statement alongside the report.

Venice will rise again!

The cities of Venice, Italy and New Orleans, Louisiana have a tremendous problem in common. They are both built on river sediments and they are both slowly sinking into the sea.

Venice (the old city) is currently virtually exactly at sea level (and sinking) while New Orleans is already around 7 feet BELOW sea level (and sinking) and has had to be protected by levees surrounding it which keep the Mississippi River and a large lake and the water from the Gulf of Mexico out.

In 2002, I realized that it was actually possible to essentially hydrostatically ‘jack up’ the massive region of Venice and the surrounding area, at a rate of about one inch (2,5 cm) per month, by using river water sent down into selective water wells to develop hydrostatic pressure down there.

If a thousand gallons of water from local rivers is sent down every minute, in each of thirty standard water wells, that water is INCOMPRESSIBLE. In a five year period of this (natural) process, we should lift Venice and the entire region by about FIVE VERTICAL FEET, thereby totally solving Venice’s problem.

The process is NATURAL (river water falling down wells to develop pressure) and amazingly cheap and easy to do! C Johnson, Theoretical Physicist, Physics Degree from Univ of Chicago, 16 Aug 2016

And what do we do now?

Our world is about to change dramatically. We have already “locked in” global average warming of at least 2 degrees, which will have major impacts on food, water and global security.

Catastrophic outcomes – including economic, social, and ecological collapses – are likely even if, as Gilding expects, we manage to engineer a global emergency response. A world where half of all species becomes extinct is likely if an additional 2 billion people try to live like those in the most developed countries.

With planetary capacity already starkly breached, what happens then? And what do we do now?

Such events, our data shows, will become even more frequent and more severe said James Hansen, director of the NASA Goddard Institute for Space Studies.

the crust beneath our feet

Reports by international groups of researchers – to be presented at a London conference next week – will show that climate change, caused by rising outputs of carbon dioxide from vehicles, factories and power stations, will not only affect the atmosphere and the sea but will alter the geology of the Earth.

Melting glaciers will set off avalanches, floods and mud flows in the Alps and other mountain ranges; torrential rainfall in the UK is likely to cause widespread erosion; while disappearing Greenland and Antarctic ice sheets threaten to let loose underwater landslides, triggering tsunamis that could even strike the seas around Britain.

“Not only are the oceans and atmosphere conspiring against us, bringing baking temperatures, more powerful storms and floods, but the crust beneath our feet seems likely to join in too,” said Professor Bill McGuire, director of the Benfield Hazard Research Centre, at University College London (UCL).

play misty for me

Enter “marine cloud brightening,” a geoengineering scheme that would increase cloud reflectivity over the ocean by spraying them with an ultrafine saltwater mist from ships.

The clouds, containing more particles, would cast enough sunlight back into space to at least partially offset the warming effects of all that CO2 from burning fossil fuels.

Stephen Salter, an emeritus professor of engineering design at the University of Edinburgh is the lead and was for many years the only engineer working on a proposal to accomplish marine cloud brightening by populating the world’s oceans with up to 1,500 ships of a somewhat exotic design—sometimes known as “albedo yachts”.

Each vessel would be remote-controlled, wind-powered, and capable of generating (via turbines dragged through the water) the electricity required to create a mist of seawater and loft it 1,000 meters into the atmosphere.

disappearing beach

Bondi beach will shrink to a thin ribbon of sand and extreme storm surges would reach the top of its concrete sea wall, research commissioned by the local council shows.

The latest report from the Intergovernmental Panel on Climate Change, released on Friday, found the sea level would rise and could be expected to be up to 80 centimetres higher by the end of the century.

In the case of an 80-centimetre rise in sea levels, high tides would regularly flood parts of many Sydney suburbs that are close to water, including sections of Annandale, Mosman, Marrickville, Brighton-le-Sands, Sylvania Waters, Five Dock and Narrabeen.

Rob Brander, a senior lecturer at the University of NSW specialising in coastal geomorphology, said Sydney’s coastal regions faced significant impacts from rising sea levels.

“If a beach shifts landward, it hasn’t got many places to go,” Dr Brander said. “Beaches will get narrower and low-lying coastal properties will face damage.”Sydney Morning Herald, 29 Sep 2013

team’s target

A team of scientists from Australia and New Zealand is warning that unless global warming can be capped at a rise of 2 degrees or less, the Antarctic Ice Shelves will collapse. They say that could add another 40cm to sea level rises by the end of the century, instead of the 5cm that has been previously forecast.

If we don’t hit that two degree target, then actually we’ve committed to several metres of sea level rise over the next few centuries, and thousands of years after that said Dr Chris Fogwill from the University of New South Wales’ Climate Change Research Centre.

polar bears get the elbow

Polar bears are likely to lose out to grizzly bears in fierce competition for food as climate change drives the two species closer together into shared habitat, biologists concluded in a study.

The research was based on 3-D computer modeling that compared the skull and jaw strength of the two bruins and found polar bears ill-suited to the tougher chewing demands posed by the largely vegetarian diet of their grizzly cousins.

This is one additional piece of evidence that things look pretty bleak for the polar bear, if current trends continue, said Graham Slater, the lead author of the research. Polar bears already are losing habitat as rising Arctic temperatures diminish the sea ice they depend on to hunt for seals.

As the ice continues to shrink, polar bears will be forced to seek additional food sources. To people who say polar bears can just change their diet, we are saying … they will have to, but it probably will not be sufficient for them, especially if they are co-existing with grizzly bears, said Blair Van Valkenburgh, senior author of the paper.

save the planet with fake trees!

Professor Klaus Lackner (Geophysics, Columbia University Earth Institute): Just like the leaves of a tree have air blowing over them, and they manage to extract some of the CO2 as it floats over the leaf’s surface, this device has surfaces over which the wind blows, and it gives up a fraction of its CO2 as it goes through. So the idea of this device is to capture carbon dioxide out of the atmosphere. Yes, it doesn’t look like a tree, because it’s just has functionally this one part in common. It doesn’t, like a normal tree, try to convert this with sunshine into starches. So the leaves of this tree do not have to be exposed to the sunshine, so they are stacked much more tightly. And, consequently, this synthetic tree is capable of collecting much more CO2 out of the wind than an ordinary tree would.

The black truffle, one of the most exclusive and expensive delicacies on the planet, is under threat from climate change.

A mysterious species of underground fungi with reported aphrodisiac and therapeutic properties, the aromatic truffles are also highly fragile and cannot withstand more than three weeks without water.

But prolonged drought in many of their prime growing regions in Europe and predictions about global warming suggest the future is about as black as the truffles themselves, to the despair of the growers.

the flight of the bumble bee

Global warming is shrinking the terrain where bumblebees live in North America and Europe, with these vital pollinators departing the southernmost and hottest parts of their ranges while failing to move north into cooler climes, scientists say.

Their study, published on Thursday, used records from 1901 to 2010 to track 67 bumblebee species, finding that the insects have surrendered about 185 miles (300 km) from the southern end of the regions they called home on both continents.

This is the ‘climate vise,’ said University of Ottawa biologist Jeremy Kerr, with the bumblebees “stuck at the northern edges of ranges while the southern edges are crushed inward and those populations are lost.”

Bumblebees are declining incredibly fast and the fingerprints of human-caused climate change are all over these changes, Kerr added. “Even more incredibly to us, these effects are often nearly identical across continents, occurring at the same pace in both Europe and North America.” Kerr said dramatic action should be considered: a proposal called “assisted migration” involving a large-scale relocation of bee populations into new areas where they might thrive.

More generally, losing pollinators is a sign that we are playing dangerously with life-support systems we can’t do without, Kerr added. “That is an experiment we should never have started.” Heat Is Online, 10 Jul 2015 – Reuters

Prominent HIV scientist Professor David Cooper, director of the National Centre in HIV Epidemiology and Clinical Research, agreed environmental change would have a negative impact on HIV sufferers.

watch where you’re standing!

A former member of the Clinton administration, and current Senior Fellow at the virtual Clinton think tank the Center for American Progress, claimed Monday that global warming might have played a factor in the collapse of the I-35W bridge in Minneapolis last week.

Writing at Climate Progress, the global warming blog of CAP, Joseph Romm – who served as Acting Assistant Secretary of the U.S. Department of Energy in 1997 and as Principal Deputy Assistant Secretary from 1995 though 1998 – stated in a piece entitled “Did Climate Change Contribute To The Minneapolis Bridge Collapse?”

“Certainly climate change will have the biggest infrastructure impact on our coastal cities, water and sewage systems, levees, and electric grid. But given that a remarkable 70,000 other bridges in the country are also structurally deficient, we should seek to learn whether such troubled bridges can take the ever-growing stresses generated by global warming.”

“We need to be as prepared as possible for a changed climate – as the Center for American Progress has previously argued. Indeed, if the adapters have their way in blocking serious efforts aimed at prevention, we’ll need to be prepared for the very worst.”

invasion of the crocodile-eating snakes!

Scientists recently found bones from a 60-million year old giant snake in Colombia—a snake that weighed a ton, and was as long as a school bus.

Paleontologist Jonathan Bloch of the Florida Museum of Natural History was on the team. He says the find also tells us about climate, because cold-blooded animals depend on ambient heat for their metabolism.

Bloch says it must have been ten degrees hotter in Colombia back then—contrary to a leading theory that tropical climates don’t change as much as others. So today’s warming trend may have an even wider impact than we thought.

Bloch’s team made some other inferences as well. For example, the snake would have been larger than anything else at the time, so it could have easily eaten whatever it liked, including primitive crocodiles!

They also suggest that the extinction of the dinosaurs may have set the stage for this giant snake to become king of the land for millions of years.

The Pacific Ocean may open a “heat vent” above it that releases enough energy into space to reduce projected climate warming caused by the build-up of greenhouse gases in the atmosphere.

High clouds over the western tropical Pacific Ocean seem to decrease when sea surface temperatures are higher, said Arthur Hou of the American space agency, Nasa.

The mechanism allows the heat to escape, keeping the oceans cool.

The newly discovered vent, if confirmed, could significantly reduce estimates of future global warming now being put forward by computer models of the Earth’s climate.

cloud ships

Special ships that create clouds by spraying seawater into the air could be the most cost effective way of tackling climate change, new research has found.

The technique, known as marine cloud whitening, would create clouds above the Pacific Ocean that would have a cooling effect by reflecting sunlight away from Earth.

A wind-powered fleet of nearly 2,000 ships would criss-cross the sea, sucking up sea water and spraying it upwards through tall funnels.

‘When you spray saltwater into the air, you create nuclei that cloud condenses around, creating bigger and whiter clouds, thus bouncing more sunlight back into space,’ said David Young from the think-tank that commissioned the study.

The paper by Professor Eric Bickel and Lee Lane looked into the costs of potential climate engineering projects. It was commissioned by the Copenhagen Consensus Centre that advises governments how to spend aid money. Daily Mail, 8 Aug 2009

bats falling like flies

Overheated flying foxes, panting and frantically fanning themselves with their wings, fell from the trees in New South Wales, Australia, six years ago.

Up to 3,500 black and grey-headed flying foxes died on the ground beneath their roosts, victims, researchers believe, of heat waves that pushed temperatures to 108 degrees F (42º C). In this era of looming climate change, such scorching temperatures are occurring more often.

Tragically so: since 1994, more than 30,000 flying foxes have died in New South Wales, apparently because of at least 19 episodes of extreme heat.

but it’s meat and drink to me!

Eating less lamb and drinking fewer pints will help save the planet, according to a Government advisor.

Diners are being encouraged to eat more pork and chicken instead, as they produce fewer carbon emissions. The study also found that alcoholic drinks contribute significantly to emissions with the growing and procesing of hops and malt into beer and whisky prodcing 1.5 percent of Britain’s greenhouse gases.

“Changing our lifesyles, including our diets, is going to be one of the crucial elements in cutrting carbon emissions,” said David Kennedy, chief executive officer of the Committee on Climate Change.

While the steady disappearance of sea ice in the Arctic has been one of the hallmark effects of global warming, research shows it is not only covering less of the planet, but it’s also getting significantly thinner.

That makes it more susceptible to melting, potentially altering local ecosystems, shipping routes and ocean and atmospheric patterns. In estimating ice thickness, satellites must try to gauge thickness differences of just a few feet from hundreds of miles above the planet’s surface.

“It’s a tricky business,” University of Washington researcher, Ron Lindsay said.

bring back Sunday!

The power of public opinion and citizen action will have a strong impact on the climate conference taking place in Copenhagen.

One thing we can easily do to achieve this goal: we can declare Sunday to be a fossil fuel-free day or a low-carbon day or at least an energy-saving day. We can start this week, this month or in 2010. We can start individually and collectively.

The long journey to cut carbon dioxide emissions can start in the here and now….in the context of excessive carbon dioxide emissions into the atmosphere, which are bringing catastrophic upheavals, we can and should restore Sunday to a day for Gaia, a day for the Earth.

poisoned chalice

“Global energy, food and water security are also poised on a knife edge…Australian leaders glibly talk about adapting to a 4-degree world with little idea of what it means – which is a world of 1 billion people rather than the present 7 billion…The damage caused by this culture threatens the very foundations of democratic society…Adversarial politics and corporate myopia are incapable of addressing life-threatening climate change.”

“The community must go around these barriers and demand leaders take urgent action before the poisoned chalice we pass to our grandchildren becomes even more toxic.” Ian Dunlop chaired the Australian Greenhouse Office Experts Group on Emissions Trading 1998-2000.

worse than we thought – toll on plants and animals!

Human-enhanced climate change is taking its toll on the world’s plants, animals and physical environment much more quickly than previously thought, scientists have warned.

An international research team has found that many accounts of plants flowering early, birds changing their migration habits, and glaciers and mountain snow melting were most likely the result of rising greenhouses gases.

Climate change from greenhouse gases is not only affecting the temperature, David Karoly, a professor from the University of Melbourne’s school of earth sciences and a member of the research team, said yesterday.

“It is already affecting ecosystems, and other systems, like glaciers. It is happening earlier than previous studies would have indicated. When you look at the different signals across the globe, you can see that message very clearly.”

water supply

Sydney’s water supply could be at risk from a growing threat of more intense and frequent bushfires brought on by extended drought and climate change, experts say.

Hotter and drier conditions related to a build-up of greenhouse gases in the atmosphere could lead to exceptionally intense bushfires, the head of the Blue Mountains World Heritage Institute, John Merson, said last week.

They might threaten the ability of eucalypt forests in the mountains to recover, he told a climate change conference in Sydney. That could lead to erosion, silting of rivers and dams, and less water trickling through to aquifers in the catchment for Sydney, Newcastle and Wollongong.

If we got into another bad bushfire year this year the ability of the forests to recover would be seriously compromised, Dr Merson said.

fish emboldened

Acidic ocean water blunts the sense of smell in fish, making them bolder – perhaps recklessly so, according to a new study offering a glimpse of the oceans of the future. The findings suggest that, if greenhouse gas emissions continue unabated, fish could suffer debilitating behavioral effects.

If reef fish behavior does not adapt to rising CO2 levels over coming generations, there could be serious consequences for the structure and function of future reef communities, the authors wrote in the study published in Nature Climate Change.

This is the first time people have been able to test what would happen in 100 years, said Danielle Dixson, an assistant professor at Georgia Tech University and co-author of the study, which was led by Australian researchers.

The differences are striking, said Karl Castillo, an assistant professor of marine sciences at the University of North Carolina who was not involved with the research. This is a strong study, Castillo said. “There’s no doubt there is something happening here due to acidification.” Heat Is Online, 14 Apr 2014 – The Daily Climate

in support of small shops

Neighbourhood shops and farmers’ market will gain currency in the coming days, as reduction in vegetable transport will help save fuel and thereby help reduce global warming, said G, Nammalvar, organic farming scientist on Thursday.

Transportation of food items formed a considerable part in the entire transport industry, he added and suggested that shops like the Greens Shop would be best answer to reduce transportation.

Dr. Nammalvar suggested that ideal situation would be one where the distance between the points of production and sale was not more than 30 km. And, the presence of farmers’ and community markets would ensure absence of middlemen.

the case of the disappearing acorns

Rod Simmons, a field botantist based in Arlington, Virginia, and Arlington naturalists began calling around.

A naturalist in Maryland found no acorns on an Audubon nature walk there. Ditto for Fairfax, Falls Church, Charles County, even as far away as Pennsylvania. There are no acorns falling from the majestic oaks in Arlington National Cemetery.

“Once I started paying attention, I couldn’t find any acorns anywhere. Not from white oaks, red oaks or black oaks, and this was supposed to be their big year,” said Greg Zell, a naturalist at Long Branch Nature Center in Arlington.

“We’re talking zero. Not a single acorn. It’s really bizarre.”

Is it climate change or could it be the extreme opposite of a natural boom-and-bust cycle?

country vs city

More rural Australians will suffer mosquito-borne diseases and food poisoning as climate change causes temperatures to rise, an academic warns.

Professor Kevin Parton, from Charles Sturt University in Orange, NSW, said rural Australians will be harder hit by climate change than their metropolitan counterparts, as health services are more difficult to access in the country.

As vectors that support and carry diseases, such as air, water and organic movement, shift in response to climate change, so too will health problems, he said.

We could see both a worsening of existing diseases as well as the spread of diseases usually associated with warmer regions, such as Ross River and Barmah Forest viral infections, move to more temperate climates.

invasion – Asian carp

They’re called Asian carp, and they emigrated to the lower reaches of the Mississippi River in the 1970s. Now they’re knocking on the door of the Great Lakes, threatening to destroy one of the most valuable aquatic regions in the U.S., unless the often fractious Great Lakes states manage to pull together and keep them out.

The situation is so serious that the White House convened an “Asian carp summit” on Monday to work out a defense plan.

Asian carp — a collection of related fish, including bighead carp and silver carp — are what’s known as an invasive species, an animal or plant that moves into a new environment, often badly disrupting it.

Invasive species are becoming more common because of international trade, which turns the planet into a giant pinball machine, transplanting wildlife from one corner of the world to another, and because of climate change, which prompts species to migrate to more hospitable environments, often at the expense of those that already live there.

If the preventive efforts don’t work, you might want to put on a helmet the next time you go waterskiing on Lake Michigan.

state of fear

Dr Pachauri supported the views of scientists who believe stabilising atmospheric carbon dioxide at 450 parts per million – a level that Professor Garnaut says is beyond reach in the short-term – was not enough. If you talk to the president of Maldives and indeed the People of the Maldive islands, they are living in a state of fear, he said yesterday. If you look at parts of Africa, by 2020 there will be 75 million to 250 million people living under water stress on account of climate change.

coral reefs utterly destroyed

Unless we change the way we live, the Earth’s coral reefs will be utterly destroyed within our children’s lifetimes, says marine scientist JEN Veron.
Ponder these facts: The atmospheric levels of CO2 we are already committed to reach, no matter what mitigation is now implemented, have no equal over the entire longevity of the Great Barrier Reef, perhaps 25 million years. And most significantly, the rate of CO2 increase we are now experiencing has no precedent in all known geological history.

rewriting history

The Black Death struck Europe in 1347, killing 30-50% of the European population in six violent years. These outbreaks were traditionally thought to be caused by rodent reservoirs of infected rats lurking in Europe’s cities, or potentially by rodent reservoirs in the wilderness.

But our research, published in the journal PNAS, suggests otherwise. We found that Europe’s plague outbreaks were indeed associated with climate fluctuations – but in Asia.

Using tree-ring based climate records from Europe and Asia, we showed that plague reintroductions into European harbours were associated with periods of wet conditions, followed by a drought, across large parts of Central Asia.

the latest loser – the lesser butterfly orchid

Climate change is likely to produce losers as well as winners in Britain’s native flora – flowers of the mountains and cooler places are expected to decline – but the survey did not pick up as much negative evidence.

More increases that may be consistent with a warming climate have been found in plants that specialise in growing on waste places, such as square-stalked willowherb and prickly lettuce.

However, there is one candidate for global warming victim, and this is once again an orchid: the lesser butterfly orchid. This is a species of northern Europe, which tends to grow on the edges of heaths and moorlands.

will you lead by example?

If it’s so hard to change the climate to suit humans, why not alter humans to suit the changing climate, philosophers from Oxford and New York universities are asking. They suggest humans could be modified to be smaller, to dislike eating meat, have fewer children and be more willing to co-operate with social goals.

Behavioural changes might not be enough, even if they are widely adopted, and international agreements for market solutions such as emissions trading are proving difficult to achieve, say Matthew Liao, of New York University, and Anders Sandberg and Rebecca Roache, of Oxford University.

They suggest hormone treatments could be used to suppress child growth, or embryos selected for smaller size. They say people who lack the motivation or willpower to give up eating meat could be helped by “meat patches” on their skin, which deliver hormones to stimulate the immune system against common bovine proteins.

“Henceforth eating ‘eco-unfriendly’ food would induce unpleasant experiences,” the authors say. Better-educated women have fewer children, so human engineering to enhance cognition could lead to fertility reduction as “a positive side effect from the point of view of tackling climate change”, the paper also argues.

human development derailed!

Climate change may be the single factor that makes the future very different, impeding the continuing progress in human development that history would lead us to expect.

While international agreements have been difficult to achieve and policy responses have been generally slow, the broad consensus is clear: climate change is happening, and it can derail human development. – United Nations Human Development report The Guardian, 5 Nov 2010

can’t see the wood for…..

If global warming really is the mother of all enveronmental probalems, then perhaps the time has come to bring to an end the clearing and logging of natural forests. This will make a significant and cost-effective contribution to solving the global warming problem.

We must not forget that the laws of science apply universally and do not recognise political boundaries. Whether a natural forest is in Tasmania, Victoria or Papua, it performs the same kind of role in the global carbon cycle and in helping to regulate atmospheric levels of carbon dioxide.

heat turned up!

The number of elderly Melburnians dying due to extreme heat is expected to rise dramatically as climate change takes hold this century, research suggests.

Nicole Joffe from consultants Net Balance found the number of days with an average temperature above 30 degrees would double by mid-century – from two to at least four a year – even if governments acted to cut greenhouse emissions. Failure to tackle climate change would trigger a steeper rise.

the private struggles of a climate scientist

For activists like Mike Tidwell — founder of the nonprofit Chesapeake Climate Action Network and author of The Ravaging Tide: Strange Weather, Future Katrinas, and the Race to Save America’s Coastal Cities — — part of being on the front lines means being outspoken and passionate about the cause.

But while activism may be a more forgiving platform to express emotional stresses than within the scientific community, the personal toll of the work goes largely undiscussed.

“You don’t just start talking about unbelievably fast sea-level rise at a cocktail party at a friend’s house,” Tidwell says. “So having to deny the emotional need to talk about what’s on your mind all the time … those are some of the burdens that climate aware scientists and activists have to endure.”

“People talk about climate change, openly talk about activism, and people even talk about how scary it is, and about how screwed we are and unbelievable it is that sea level is rising, and world governments still aren’t doing sXXX. But nobody talks about how it makes them feel personally.”

no-one spared, not even retrospectively!

A study of woolly mammoths has added to evidence they were wiped out by climate change, scientists say.

British and Swedish researchers sequenced DNA from 88 samples of bone, tooth and tusk, looking for a signature in the genetic code handed down on the maternal line. They used this telltale sign to build a family tree of mammoths spanning 200,000 years.

A warm period 120,000 years ago caused populations to decline and become fragmented. Wrangel Island, in the Siberian Arctic, and the island of St Paul, off Alaska, are believed to have been the mammoths’ last refuge. Sydney Morning Herald, 12 Sep 2013 – screencopy held by this website

giant sunshade

Professor Roger Angel thinks he can diffract the power of the sun by placing trillions of lenses in space and creating a 100,000-square-mile sunshade.

Each lens will have a diffraction pattern etched onto it which will cause the sun’s rays to change direction. He intends to use electromagnetic propulsion to get the lenses into space. If work was started immediately Prof Angel thinks the sunshield could be operation by 2040.

He said: “Things that take a few decades are not that futuristic.”

Have you hypermiled lately?

Real men hypermile.

That’s the “attempt to maximize gas mileage by making fuel-conserving adjustments to one’s car and one’s driving techniques,” according to the Oxford American Dictionary, which named “hypermiling” the 2008 word of the year.

Hypermiling techniques include keeping tires perfectly inflated, killing engines at stoplights, turning off the air-conditioning and driving at a steady speed, with as little rapid acceleration or deceleration as possible.

Originally coined in 2004 by a driver named Wayne Gerdes, who has earned several gas-mileage records, hypermiling really caught on in 2008 as gas prices passed $4 a gallon in much of the country. Time, 3 Nov 2008

cokcroaches on the march!

Climate change is being blamed for a changing of the guard among Sydney’s cockroach population.

Researchers say the most common sub-species in city households was the german cockroach, until it disappeared about seven years ago. Martyn Robinson from the Australian Museum says the Australian house cockroach, methana marginalus, which likes warmer climates, has begun moving in.

It’s most likely to be the…warmer climate, he said. They certainly have appeared for many many years just on little spot occurrences where somebody will find this funny little cockroach that’s probably come in on their suitcase from a trip up to Queensland.

missing link found!

A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere that incorporates scores of physical and chemical environmental processes.

The new findings, to be published in Geophysical Research Letters, come to light just after the Environmental Protection Agency’s recent ruling against states setting specific emission standards for this greenhouse gas based in part on the lack of data showing the link between carbon dioxide emissions and their health effects.

While it has long been known that carbon dioxide emissions contribute to climate change, the new study details how for each increase of one degree Celsius caused by carbon dioxide, the resulting air pollution would lead annually to about a thousand additional deaths and many more cases of respiratory illness and asthma in the United States, according to the paper by Mark Jacobson, a professor of civil and environmental engineering at Stanford.

Worldwide, upward of 20,000 air-pollution-related deaths per year per degree Celsius may be due to this greenhouse gas.

Dear Earth, are you listening?

Dr. Sarah Perkins, a climate scientist and extreme events specialist with the University of New South Wales, shared both her concern and hope about our Earth.

“For sometime now I’ve been terribly worried. I wish I didn’t have to acknowledge it, but everything I have feared is happening. I used to think I was paranoid, but it’s true. She’s slipping away from us. She’s been showing signs of acute illness for quite a while, but no one has really done anything.

Her increased erratic behavior is something I’ve especially noticed. Certain behaviors that were only rare occurrences are starting to occur more often, and with heightened anger. I’ve tried to highlight these changes time and time again, as well as their speed of increase, but no one has paid attention.

It almost seems everyone has been ignoring me completely, and I’m not sure why. Is it easier to pretend there’s no illness, hoping it will go away? Or because they’ve never had to live without her, so the thought of death is impossible? Perhaps they cannot see they’ve done this to her. We all have. To me this is all false logic. How can you ignore the severe sickness of someone you are so intricately connected to and dependent upon.

How can you let your selfishness and greed take control, and not protect and nurture those who need it most? How can anyone not feel an overwhelming sense of care and responsibility when those so dear to us are so desperately ill? How can you push all this to the back of your mind? This is something I will never understand. Perhaps I’m the odd one out, the anomaly of the human race. The one who cares enough, who has the compassion, to want to help make her better.

The thing is we can make her better!! If we work together, we can cure this terrible illness and restore her to her old self before we exploited her. But we must act quickly, we must act together. Time is ticking, and we need to act now.”

water shortages

Global warming could bring water shortages to one in six people around the world, scientists have warned. Because higher temperatures would bring less snow and more rain, the ice would soon run out, bringing water shortages.

world trapped in paradigmatic lock!

The UFO phenomenon has become part of the news for many decades. Meanwhile, our planet entered a crucial phase of its history like nobody has known before, when mankind obtained technical means allowing to seriously deteriorate its environment, and beyond, to destroy any life on Earth. Among most visible signs, global warming is obvious.

While our technology sees a spectacular progress, our fundamental knowledge tramples more and more. In our opinion, this is the consequence of immutable dogmatic prejudices, a refusal of any really innovative fundamental scientific idea, in particular any change in our comprehension of the universe which could make interstellar travel possible, therefore incursions of visitors coming from stellar systems located at several tens light-years from ours, or even more.

The systematic brake to engage a true research, focusing on a rational and scientific investigation of the UFO file, is also for us a cloistering of the thought, a paradigmatic lock.
