blame us for the moose and the wolves!

Global warming is impacting more than the water levels in the Great Lakes.

It could be the beginning of the end for the moose and wolves of Isle Royale. And if it is, a Michigan Technological University scientist places the blame squarely on the human race.

“Humans have made summers increasingly hot, which likely exacerbates moose ticks,” says John Vucetich, a population biologist in Michigan Tech’s School of Forest Resources and Environmental Science.

“Both the heat and the ticks are detrimental to moose. If wolves go extinct for a lack of moose, humans will be to blame.” Science Daily, 22 Aug 2007

holiday horror stories

A report commissoned by the World Wide Fund for Nature (UK) says heat waves, droughts, rising sea levels, flash floods, forest fires and disease “could turn profitable tourist destinations into holiday horror stories”.

The senior research scientist at the unit, Dr David Viner, said: “Areas like the Mediterranean could become unbearable during the traditional summer holiday season. As temperatures begin to soar, many tourists will stay away.”

Dr Ute Collier, WWF head of climate change, said: “The tourism industry could be faced with huge costs as global warming begins to influence decisions about when and where people are going to go on holiday.”

WWF’s recommendations include introducing an aviation fuel tax throughout the European Union, and preferably worldwide.

It also argues for a shift from fossil fuel use to renewable energy sources, and for improved energy efficiency in new buildings, including tourist resorts.

do you want grasshoppers with that?

We cannot continue the way we are producing and consuming meat.

Obviously, this should not go as far as governments telling people what to eat. However, keeping meat consumption to levels recommended by health authorities would lower emissions and reduce heart disease, cancer, and other diseases. And of course there are alternative sources of protein.

For example, raising insects as an animal protein source. Insects have a very good conversion rate from feed to meat. They make up part of the diet of two billion people and are commonly eaten in many parts of the world.

Eating insects is good for the environment and balanced diets.

a glass ceiling?

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 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.

Despite the obvious obstacles – including an estimated $350 trillion (244 trillion pound) price tag for the project – Dr Angel is confident of getting the project off the ground.

mixed results for weeds

Weeds from warm climates are poised to claim new turf as temperatures increase. But other invasives may lose ground.

Princeton researchers Bethany Bradley, Michael Oppenheimer and David Wilcove used computer models of global climate change to predict the future ranges of weeds that are widespread in the West.

Just as native species are expected to shift in range and relative competitiveness with climate change, they wrote in a study published in the journal Global Change Biology, “the same should be expected of invasive species.”

Using each weed’s preferred habitat characteristics and a scenario in which fossil fuel emissions are not reduced, Bradley and her colleagues created an invasion risk map for each weed. Their results were mixed.

The bad news for California: yellow star thistle will keep its current range and probably spread farther here and in Nevada.

Tamarisk, an exotic tree that sucks wildland creeks dry, will neither gain nor lose in a warmer West. The largest effects the Princeton group predicted were for cheatgrass and leafy spurge, which will shift their ranges north, and spotted knapweed, which will move to higher elevations.

a safe earthquake

Efforts to stem global warming by pumping emissions of carbon dioxide deep into the Earth’s crust could trigger widespread earthquakes, a Stanford geophysicist warned.

Although those quakes would not be particularly destructive, they would be widely felt and disruptive – and it would also cost billions of dollars to create thousands of disposal sites for the greenhouse gas, said Mark Zoback, one of the country’s leading seismic experts.

Injecting carbon dioxide into thousands of sites in mid-America, he said, would increase the pressure along those faults and inevitably push many into abrupt failure. The result would be quakes with magnitudes of up to 4, he said.

Another serious problem with the sequestration proposals is that many injection wells would be drilled deep into rock and sand formations that are not impermeable, raising the possibility that much if not all of the carbon dioxide could escape into the atmosphere and start the greenhouse problem once again, Zoback said.

baby walruses all at sea

Melting Arctic ice may be putting walrus pups in peril, researchers say. A team of scientists working in the Arctic Ocean in 2004 says it encountered nine Pacific walrus pups struggling alone in the water far from shore.

“I’m not a walrus expert, but we thought it was unusual,” said Lee Cooper, a marine ecologist at the University of Tennessee in Knoxville, who led the team.”

“The baby walruses would swim up to the boat. It was heartbreaking,” he said.

Melting Arctic sea ice is the most likely explanation for the stranded pups, Cooper said. His team was in the region to study the intrusion of warm Bering Sea water into the Arctic Ocean. National Geographic, 27 Mar 2006

ban livestock!

According to a new report published by the United Nations Food and Agriculture Organization, the livestock sector generates more greenhouse gas emissions as measured in CO2 equivalent – 18 percent – than transport.

It is also a major source of land and water degradation.

climate change hits a sour note

But closer to home, you don’t have to look far for concrete examples of climate change, says Eugenia Choi, a UBC assistant professor of music.

Take her 300-year old, handcrafted Stradivarius violin. It’s not that they don’t make them like they used to, it’s that they can’t.

“For musicians, our instruments connect us to a natural world very much threatened by climate change,” Choi says. “People wonder why a fine violin can cost more than a house.”

“Largely, it’s because global warming has changed how trees grow. You can no longer create new violins of the same quality. There just aren’t the same types of wood or density.”

bees dying like flies!

More than 100 previous studies have shown that elevated levels of atmospheric carbon dioxide decrease the nutritional value of plants, such as wheat and rice.

But the goldenrod study, published last month, was the first to examine the effects of rising CO2 on the diet of bees, and its conclusions were unsettling: The adverse impact of rising CO2 concentrations on the protein levels in pollen may be playing a role in the global die-off of bee populations by undermining bee nutrition and reproductive success.

“Pollen is becoming junk food for bees,” says Lewis Ziska, a plant physiologist at the U.S. Department of Agriculture’s (USDA) Research Service in Maryland and lead author of the study.

The study itself concluded that the decline of plant proteins in the face of soaring carbon dioxide concentrations provides an “urgent and compelling case” for CO2 sensitivity in pollen and other plant components. Heat Is Online, 15 May 2016 Environment 360.Yale.edu

early birds beat the rush

As global warming brings an earlier start to spring, the early bird might not just get the worm.

It might also get its genes passed on to the next generation. Because plants bloom earlier in the year, animals that wait until their usual time to migrate might miss out on all the food.

Those who can reset their internal clocks and set out earlier stand a better chance at having offspring that survive and thus pass on their genetic information, thereby ultimately changing the genetic profile of their entire population.

Dead and low-life zones in the world’s oceans are expected to expand as global warming continues to raise aquatic temperatures, according to a new report by researchers from the University of Kiel, Germany, and published in the journal Science.

Frank A. Whitney of the Canadian Institute of Ocean Sciences also warned that the biological consequences of oceanic oxygen loss will be severe.

“Many species will lose their deep habitat, meaning competition will become stronger in the remaining favorable habitat, and increased vulnerability to predation will likely occur,” he said.

fish left in the dark

Climate Change Could Harm Lake Fish: Light Determines Growth Of Fish In Lakes.

“In the brownest lakes sunlight can’t penetrate more than about two meters. In clear mountain lakes, the light can reach down to depths of 15-20 meters and lead to high production of algae on lake bottoms,” says Jan Karlsson, associate professor at Climate Impacts Research Center (CIRC).

The problem is that the algae that live on the lake bottom need sunlight for their photosynthesis. The algae provide food for various bottom-dwelling animals, which in turn are eaten by fish.

Limited light penetration thus has negative consequences for all living beings in a lake. Light is what determines the growth of fish in lakes. Climate change is expected to lead to browner lakes with less light penetration, which will lead to reduced growth of fish. Science Daily, 18 Aug 2009

a bargain at $40 billion

Australia could move to 100 per cent renewable energy within a decade if it spent heavily on cutting-edge solar thermal and wind technology, according to an analysis released as part of a community bid to redirect the flailing climate policy debate.

The shift would require the annual investment of up to $40 billion – roughly 3.5 per cent of national GDP – with the largest chunk going towards solar thermal power plants that used molten-salt heat storage to allow power generation to continue without sunlight.

Public transportation takes us there!

There are many different measures that we all can take to reduce global warming, however the most popular method that we can do this is to take public transportation.

In recent studies, conclusive evidence indicates that transportation by way of personal vehicles accounts for well over one fourth of all of the emissions of carbon dioxide in the country today. However, public transportation has resulted in many different types of savings.

These savings include just over one billion gallons of fuel, as well as one and a half million tons of the dangerous emissions of carbon dioxide on a yearly basis.

VisitBritain gets a boost

Climate change could “dramatically” change the face of British tourism in the next 20 years, with European tourists flocking to the UK to escape unbearably hot continental summers, experts say.

Research shows that European tourists may choose to holiday in Britain as resorts nearer to home become too hot. Weather changes may provide revival opportunities for northern seaside towns such as Blackpool and put new strains on roads and development in southern coastal resorts, a study in the Journal of Sustainable Tourism said.

Academic David Viner, a researcher at the University of East Anglia’s Climatic Research Unit in Norwich, produced the report after analysing the work of experts around the globe.

“The likelihood [is] that Mediterranean summers may be too hot for tourists after 2020, as a result of too much heat and water shortages,” the study said.

There were “opportunities for the revival of northern European resorts, including Blackpool, in the next 20 years, as climate change and rising transport costs offer new holiday opportunities,” it said.

less call for call girls

Global warming and increasing temperatures will cause decreasing birthrates and lower paychecks for prostitutes. Researchers have released a study that suggests that higher temperatures make for lower sex drives.

The study, conducted by the National Bureau of Economic Research, found that birth rates have had a tremendous decline nine months after a particularly hot day, going down as much as 0.7% as cooler days.

From this they drew two conclusions: either heat reduces fertility or less desire to have sex.

The team also found that days with temperatures exceeding 80 degrees result in a significant decline in birth rate 8-10 months later, though they rebound after a few months.

choosy cattle

Most climate models paint a bleak picture of the Great Plains a century from now as a hot region besieged by heavy rainstorms and flooding.

And new studies suggest that climate change may bring farmers another headache: more invasive plants. And they can’t count on cattle to gobble them up. Depending on the plant, most cattle either don’t want to eat it or could get sick if they do.

“You kinda have to teach them about a new plant,” says Ellen Nelson, a rancher in north-central Colorado who has a weed problem. “I’ve gotten some of them to eat some, but in general, that’s a hard one.” npr.org, 25 Mar 2014

destruction by thirds

Global warming presents the gravest threat to life on Earth in all of human history.

The planet is warming to a degree beyond what many species can handle, altering or eliminating habitat, reducing food sources, causing drought and other species-harming severe weather events, and even directly killing species that simply can’t stand the heat.

In fact, scientists predict that if we keep going along our current greenhouse gas emissions trajectory, climate change will cause more than a third of the Earth’s animal and plant species to face extinction by 2050 — and up to 70 percent by the end of the century.

nuclear on the march

Nuclear power is back on the march. Reviled and rejected for 25 years as man’s most dangerous and unsustainable fuel source, its friends are now billing nuclear power as the only practical way of countering climate change, oil shocks and landscape destruction in the west.

So, is it possible that public opinion is wrong, and that nuclear should be the fuel of choice of the future? Absolutely, says Tony Blair, who last month told MPs that America was pressing Britain to re-examine the case for building a new generation of nuclear power stations.

Nuclear must stay on the agenda “if you are serious about the issue of climate change”.

Definitely, says the independent scientist James Lovelock, who has repeated his lifelong support for nuclear energy and recently argued that civilisation is in “imminent danger” from global warming and must use nuclear power – “the one safe, available, energy source” – to avoid catastrophe.

Perhaps, say some of Britain’s leading environmental thinkers, who are calling for a debate about whether nuclear needs to be reassessed, and whether it should even be compared to other forms of renewable energy.

tsunami to hit Britain!

It was not just the warming of the sea that was the problem, added Professor Mark Maslin of UCL.

As the ice around Greenland and Antarctica melted, sediments would pour off land masses and cliffs would crumble, triggering underwater landslides that would break open more hydrate reserves on the sea-bed. Again there would be a jump in global warming.

“These are key issues that we will have to investigate over the next few years,” he said.

There is also a danger of earthquakes, triggered by disintegrating glaciers, causing tsunamis off Chile, New Zealand and Newfoundland in Canada, Nasa scientist Tony Song will tell the conference.

The last on this list could even send a tsunami across the Atlantic, one that might reach British shores.

early bird

Allen Hurlbert and Zhongfei Liang used more than 48 million observations from amateur birdwatchers to conclude that every 1.8-degree rise in temperature makes birds reach their migration milestones 0.8 days earlier on average (though much more for some species in some locations).

That’s less than 11 hours per degree, so who gives a titmouse’s mouse tit? Well, birds do, or would if they had brains big enough to contain a large-scale self-preservation instinct.

Says Hurlbert: Timing of bird migration is something critical for the overall health of bird species. They have to time it right so they can balance arriving on breeding grounds after there’s no longer a risk of severe winter conditions.

If they get it wrong, they may die or may not produce as many young. A change in migration could begin to contribute to population decline, putting many species at risk for extinction.

Why a duck?

The gradual warming of the Upper Midwest could cut the duck population in half as early as 2050, according to a new study published in the journal BioScience.

The study looked at how climate change could affect the Upper Midwest, where North America’s best duck breeding grounds are, over the next 50 to 100 years.

The study’s predictions left Duluth conservationist Dave Zentner dumbfounded. Zentner coordinated a rally for ducks, wetlands and clean water in April that drew an estimated 4,000 people to the state Capitol.

He said wetland losses should concern hunters and anyone else who cares about trumpeter swans, gulls, terns, bitterns, night herons and other wildlife that depend on wetlands. I would hope that duck hunters would take this seriously and realize that this is not far-fetched theory, he said.

“This is a real threat and the country needs to develop policies for it.”

take your pick

But there are some who literally worry themselves sick over the environment, and those people have what is known as eco-anxiety.

These people obsess over the environmental impact of everything they do, to the extent that they lay awake at night worrying about that jar they accidentally threw away instead of recycling, or what sorts of environmental catastrophes their unborn grandchildren will be dealing with.

As you can imagine, there are some people who believe eco-anxiety is ridiculous. It would be easy to write it off as the “disease du jour,” nothing more than an excuse people could use to seek attention.

While that’s certainly possible, I’m inclined to take it a bit more seriously — after all, anxiety is a common and serious affliction, and there’s plenty out there to overwhelm any of us.

save the camels!

The world’s association of camel scientists fought back angrily over Australian plans to kill wild dromedaries on the grounds that their flatulence adds to global warming.

The idea is “false and stupid… a scientific aberration”, the International Society of Camelid Research and Development (ISOCARD) said yesterday, adding the animals were being made culprits for a man-made problem.

We believe that the good-hearted people and innovating nation of Australia can come up with better and smarter solutions than eradicating camels in inhumane ways, it said.

The kill-a-camel suggestion is floated in a paper distributed by Australia’s Department of Climate Change and Energy Efficiency, as part of consultations for reducing the country’s carbon footprint.

The scheme is the brainchild of an Adelaide-based commercial company, Northwest Carbon, a land and animal management consultancy, which proposes whacking feral camels in exchange for carbon credits. The Herald Sun, 5 Jul 2011

people in …

As the country faces acute power shortage and the global warming debate hots up, energy conservationists caution against growing number of buildings with glass facades dotting the landscapes of cities as being responsible for energy consumption much in excess that a normal structure would do.

If you see the structures that have come up recently, they are all mostly made with glass. Right from top to below, you can see huge shinning glass.

Though these buildings look very contemporary and stylish, they are the biggest culprit when it comes to energy consumption, says Harsh Narang, director, Modern India Architects.

Glass building are a very European concept because they don’t get much of sunlight. Hence, their main aim is to get maximum sunlight. But, in our country where temperatures at times go as high as 50 degrees Celcius, these glasses take in more of sunlight.

Hence, the offices use more air-conditioners directly resulting in higher consumption of electricity and also in the form of carbon-dioxide emission and also CFCs that air-conditioners generate causing damage to the ozone layer, he adds.

According to a study conducted by Chartered Institution of Building Services Engineers, London, a complete glass building consumes four times more electricity than a normal building.

eco-discount

A Berlin brothel is claiming the title of Germany’s first “green” sex establishment after offering clients eco-discounts if they can prove they arrived by bicycle or public transport.

The concept has been dreamed up by the Maison d’Envie (House of Desire) brothel in the city’s fashionable Prenzlauer Berg district where Germany’s Green party won 46 per cent of the vote in last month’s general election.

Regina Goetz, the former prostitute who runs the establishment, explained yesterday: “The environment is on everyone’s lips around here and it’s pretty hard to find a parking space, so we came up with the idea of an eco-discount of €5 (£4.60) for anyone who leaves the car at home.”

thinner shellfish shells

The number of shelled creatures in the ocean is truly dizzying. And we need them — they are keystone species for everything from building coral reefs to anchoring the ocean food chain to making a killer linguine and clam sauce.

But as carbon dioxide builds up in the atmosphere, ocean water becomes more acidic. And shellfish have trouble growing their shells.

Scientists have worried for years about ocean acidification affecting shelled creatures in the future, but according to a new study, it’s already happening, and has been for over a hundred years.

Led by Christopher Gobler of Stony Brook University in New York, a team of researchers grew Northern quahog clams and Atlantic bay scallops under varying CO2 concentrations. What was surprising was how sensitive the animals were to increasing CO2.

In the researchers’ experiment, that was already enough to stunt shellfishes’ growth and make their shells thinner.

global catastrophe!

Climate change over the next 20 years could result in a global catastrophe costing millions of lives in wars and natural disasters.

A secret report, suppressed by US defence chiefs and obtained by The Observer, warns that major European cities will be sunk beneath rising seas as Britain is plunged into a ‘Siberian’ climate by 2020. Nuclear conflict, mega-droughts, famine and widespread rioting will erupt across the world.

The document predicts that abrupt climate change could bring the planet to the edge of anarchy as countries develop a nuclear threat to defend and secure dwindling food, water and energy supplies.

The threat to global stability vastly eclipses that of terrorism, say the few experts privy to its contents. An imminent scenario of catastrophic climate change is ‘plausible and would challenge United States national security in ways that should be considered immediately’, they conclude.

As early as next year widespread flooding by a rise in sea levels will create major upheaval for millions.

putting the squeeze on Salamanders

Wild salamanders that live in the Appalachian Mountains are shrinking because they must burn more energy as the local climate gets hotter and drier, according to a new study.

Researchers found that the salamanders they collected between 1980 and 2012 were 8 percent smaller than those collected in earlier decades, starting in 1957.

The findings confirm predictions that some species will shrink in response to climate change. The climate where the salamanders live has gotten warmer and drier, researchers said.

We compared the size of the museum specimens to the current animals and we were surprised to see that, in fact, many species has become smaller over just a 50- to 60-year period, said study author Karen Lips, a biologist at the University of Maryland.

Scientists have documented that increasing numbers of black brant are skipping that far southern migration and staying in Alaska instead.

Fewer than 3,000 wintered in Alaska before 1977. In recent years, however, more than 40,000 have remained north, with as many as 50,000 staying there last year, during the most ice-free winter that the Izembek National Wildlife Refuge had seen in more than a decade.

The temperatures now in winter are much warmer, said David Ward, a researcher at U.S. Geological Survey’s Alaska Science Center, who conducted the research along with scientists from the U.S. Fish and Wildlife Service.

“In years past you’d often have ice that would build up in these lagoons, and the eelgrass would be unavailable for the winter period. But now that’s changing.”

A proposal to reverse climate change by placing mirrors in the sky to reflect sunlight away from Earth won’t give us back the same climate we had before we started emitting so much carbon dioxide, says a new study.

Researchers at the University of Bristol in the United Kingdom applied state-of-the-art global climate models to predict the effect of using reflective sunshades to send a fraction of the sunlight that enters Earth’s atmosphere back into space before it can heat things up.

Although we managed to cancel out warming on a global average, what you end up with is some areas that warm up and some that cool down, said Dan Lunt, who led the study, published in Geophysical Research Letters. Heat Is Online – originally Discovery.com, July 8, 2008

Belgian scientists have identified a hitherto unsuspected benefit of global warming – more time for all of us. They say increasing levels of carbon dioxide (CO2) in the atmosphere will slow the Earth’s rotation.

One of the team, Dr Olivier de Viron, told BBC News Online: “When you increase the amount of CO2, you perturb the atmosphere’s dynamics, the winds and so on. We know that globally the wind blowing from West to East will increase, so the Earth’s rotation will decrease. “The days will be longer – and the nights won’t be shorter to compensate.”

“It means 24 hours won’t be 24 hours any more. It will be something a little bit more.”

delving into deep frames

Communicating the climate message to inform, but also engage and influence behaviour has proven intensely difficult. Over a decade of research on this issue has highlighted the need for communication to engage with people’s “deep frames” – beliefs formed over a lifetime, which are mostly subconscious.

My research paper, recently published in WIRES Climate Change draws upon cognitive science, evolutionary psychology and philosophy, among other fields, to explore the emerging idea that global warming exceeds modern humans’ cognitive and sensory abilities. To overcome this impasse, climate communication needs to engage people at a philosophical, sensory and feeling level.

People need to be able to feel and touch the new climate reality; to explore unfamiliar emotional terrain and be helped to conceive their existence differently. How is this to be done? The world must turn to its artists: storytellers, film-makers; musicians; painters and multi-media wizards, to name a few.

Under the global Future Earth initiative, a team of around 60,000 scientists and social scientists has been assembled to understand and report on the physical, tangible dimensions of the problem.

I argue we need 60,000 arts and humanities experts to focus upon the intangibles – the communication, engagement and meaning-making aspects of the problem.

window closing

The report by the Intergovernmental Panel on Climate Change, whose wording was agreed in Brussels only yesterday after all-night disputes between scientists and governments and last-minute objections from the US, China and Saudi Arabia over wording and graphics, bluntly says: “Unmitigated climate change would, in the long term, be likely to exceed the capacity of natural, managed and human systems to adapt.”

In a sobering assessment, the report finds this warming would mean “approximately 20 per cent to 30 per cent of plant and animal species assessed so far are likely to be at increased risk of extinction”.

It also warns of malnutrition, water shortages, disease and injury from predicted increases in heatwaves, droughts, storms and other severe weather events. Professor Terry Hughes, of James Cook University, who contributed to the report, said time was running out for coral reefs.

“We have a narrow window of opportunity – no more than 20 years to achieve decisive cuts in greenhouse gases – to protect coral reefs from massive degradation,” he said.

bye, bye…

Populations of the rusty blackbird, a once-abundant North American species, have declined drastically in recent years, and Auburn University researchers say climate change is to blame.

That’s the finding of graduate students Chris McClure, Brian Rolek and Kenneth McDonald published recently in the scientific journal Ecology and Evolution.

Under the direction of ornithology professor Geoffrey Hill, McClure, Rolek and McDonald studied the blackbird decline and wrote the paper “Climate change and the decline of a once common bird.”

“Changing climate is affecting everything,” McClure said. “These birds used to be everywhere and usually when people are talking about climate change, you look at the effects on an isolated species, such as some rare bird on a mountaintop somewhere.”

“But our research proved that it has a much wider effect. These birds literally span an entire continent, living in different climates, and yet they are affected just as much as anything else.”

Global warming is bringing more warmer-climate creatures to Finland, including moths that feast on human blood, according to nature researchers.

Insect-watchers are spotting more and more calpe moths in the Nordic country, which used to be considered too cold for the insects from southeast Asia, Finnish nature magazine “Suomen Luonto” reported in its June edition.

The journal published what it said were the first pictures showing the moths — calyptra thalictri — sucking human blood. The species was first sighted in Finland in 2000, but more than 100 of them have been counted since then, the journal said.

global warming explained

The current situation – the Poles glaciers’ melting is accelerating. The climate and geological changes will be increased because the planet Eris/ Nibiru hasn’t even been close to Pluto, its nearest point to Earth is supposed to happen between 2010 and 2012.

At present identical phenomena (global warming, volcanoes activation, etc.) also take place on other planets from our solar system because of Eris/ Nibiru.

Few examples: The Neptune’s moon, Triton is warming (BBC Science & Technology News, July 25, 1999), The Neptune’s moon, Triton is warming (BBC Science & Technology News, July 25, 1999), Pluto experiences an extraordinary heating (Massachusetts Institute of Technology News, October 9, 2002), Volcanic eruption on Jupiter’s satellite Io (Icarus Astronomy, November 2002), The warming of Mars (ABC News, December 7, 2002), The warming of Saturn.

Scientists of the UCLA (University of California, Los Angeles) – physics and astronomy department and those at the University of Boston have noticed that the temperature of the superior atmosphere of Saturn is higher that estimated.

Thus, professor Alan Aylward at UCLA considers necessary the reexamination of the main hypotheses regarding the planetary atmosphere and establishing the cause of the respective heating.

He also noticed a similar process on Mars, concluding: “Studying the aspects within other planetary atmospheres will help us to find out clues of the Terra’s future.”

beavers blamed!

Beavers are contributing to climate change, adding an estimated 800 million kg of methane to the atmosphere every year, scientists have found.

In their work published in the Springer journal AMBIO, experts note that carbon builds up in oxygen-poor pond bottoms like those created by beavers, and methane is generated. The gas cannot be dissolved and is released into the atmosphere.

Researchers at the University of Saskatchewan in Canada have found this methane release from beaver ponds is now 200 times higher than it was a century ago.

Lead author Colin J Whitfield and his team estimated the size of the current global beaver population and the area covered by their ponds to work out the methane release.

Whitfield said: “The dynamic nature of beaver-mediated methane emissions in recent years may portend the potential for future changes in this component of the global methane budget. Continued range expansion, coupled with changes in population and pond densities, may dramatically increase the amount of water impounded by the beaver.”

“This, in combination with anticipated increases in surface water temperatures, and likely effects on rates of methanogenesis, suggests that the contribution of beaver activity to global methane emissions may continue to grow.” International Business Times, 17 Dec 2014

rainbow faces cut-throat competition

Montana’s Flathead Basin has long been a spawning haven for the westslope cutthroat trout. But as waters in the region warm, rainbow trout have swum up from the western lakes where they were introduced decades ago to cutthroat native grounds.

As rainbow trout meet and interbreed with dwindling cutthroat trout populations, the survival of cutthroat trout is at risk. Instead, a hybrid species is taking its place.

“It’s a major cause of species extinction—lots of species are now disappearing because they are being genetically swamped by other, commoner ones,” said Stuart Pimm, a professor of conservation ecology at Duke University.

In some cases, hybridization can lead to reduced genetic diversity in animals, according to David Tallmon, an associate professor of biology at the University of Alaska. “Rather than growing a new branch on the [genetic] tree, you have two branches growing together,” he said.

In the case of cutthroat-rainbow trout hybrids, the hybrids are less genetically fit, with offspring of the hybrids struggling to survive, a study led by researchers from the U.S. Geological Survey found.

glass for a day

Given that Australia produces the second highest greenhouse gas emissions per person in the world after the US, will the average urban Australian come on board? Giselle Wilkinson, 53, admits it’s sometimes a struggle.

As we talk, Wilkinson, who lives in Heidelberg Heights in Melbourne, with her daughters, Mereki, 20, and Hannah, 19, stirs a neat bunch of garden fresh lemon balm in the teapot.

Stuck on a cabinet above her is a note – “Choose your glass for the day” – to save on washing up. The Sun Herald (Sydney), 29 Jul 2007 – screen copy held by this website

escape corridor

Australia will create a wildlife corridor spanning the continent to allow animals and plants to flee the effects of global warming, scientists say.

The 2,800-kilometre climate “spine”, approved by state and national governments, will link the country’s entire east coast, from the snow-capped Australian alps in the south to the tropical north – the distance from London to Romania.

The corridor, under discussion since the 1990s as the argument in support of climate change strengthened, will link national parks, state forests and government land. It will help preserve scores of endangered species.

new culprit identified!

In the charge against global warming, carbon dioxide has long held sway as public enemy number one. But now, less-recognized molecules are entering the fray as significant agents of global warming.

Aerosols emitted from smokestacks, exhaust pipes and domestic cooking fires consist of substances such as sulphates and nitrates that scatter light and have a local cooling effect; they also contain black carbon — or soot — a byproduct of incomplete combustion, which absorbs light.

In a study published recently in Nature2, Veerabhadran Ramanathan, an atmospheric scientist at the Scripps Institution of Oceanography in La Jolla, California, and colleagues, report that aerosols locked up in brown clouds over Asia are significant contributors to regional warming.

“Brown clouds from the United States cover the Atlantic, the European brown cloud goes over central Asia, and China’s brown cloud crosses the Pacific over to us,” says Ramanathan. “We are each a back yard to someone else, and we’re polluting every other person’s back yard.”

industrial civilisaton to collapse!

New scientific models supported by the British government’s Foreign Office show that if we don’t change course, in less than three decades industrial civilisation will essentially collapse due to catastrophic food shortages, triggered by a combination of climate change, water scarcity, energy crisis, and political instability.

The new models are being developed at Anglia Ruskin University’s Global Sustainability Institute (GSI), through a project called the ‘Global Resource Observatory’ (GRO).

Last year, Dr. Graham Turner updated his CSIRO research at the University of Melbourne, concluding that:

“… the general onset of collapse first appears at about 2015 when per capita industrial output begins a sharp decline. Given this imminent timing, a further issue this paper raises is whether the current economic difficulties of the global financial crisis are potentially related to mechanisms of breakdown in the Limits to Growth BAU [business-as-usual] scenario.”

back to the …

Here’s a simple solution to global warming: vacuum carbon dioxide out of the air.

Klaus Lackner, a physicist at Columbia University, said placing enough carbon filters around the planet could reel the world’s atmosphere back toward the 18th century, like a climatic time machine.

He estimates that sucking up the current stream of emissions would require about 67 million boxcar-sized filters at a cost of trillions of dollars a year.

The orchards of filters would have to be powered by complexes of new nuclear plants, dams, solar farms or other clean-energy sources to avoid adding more pollution to the atmosphere. LA Times, 29 Apr 2008

clam-gobbling rays reach Japan!

Warming tied to spread of clam-gobbling ray. A species of ray that is usually found in tropical and subtropical waters has been seen in waters around Japan in recent years and is believed to be responsible for damaging the local shellfish habitat.

The long-headed eagle ray, whose scientific name is Aetobatus flagellum, has been spotted in the Ariake Sea and Seto Inland Sea in western Japan.

Scientists believe that a rise in sea temperature is responsible for the expansion of the creature’s habitat.

While a theory has it that sea temperature rises in the Pacific Ocean are part of long-term temperature fluctuations, many scientists believe that global warming is responsible for the phenomenon.

save the bread basket!

But the area known as the cradle of civilization is now under serious threat.

Before the end of this century, the Middle East’s legendary bread basket could dry up as a result of global warming, to the extent that it is no longer suitable for traditional rain-fed agriculture — destroying its existence as an agrarian landscape.

However, Pinhas Alpert, a professor of atmospheric sciences at Tel Aviv University believes the Fertile Crescent can still be saved.

“It depends very much on how the world will react, whether the world will really take serious action as is needed (against climate change),” he says.

locusts on the wane

It’s not often we can report on some good news associated with climate change. But it seems that warming temperatures could give welcome respite to farmers – in China, at least – by suppressing locust plagues.

Zhibin Zhang of the Chinese Academy of Sciences and colleagues found that the Oriental migratory locust (Locusta migratoria manilensis), which has been named as one of the most damaging agricultural pests in Chinese history, operates on a climate-driven cycle.

Every 160 to 170 years, the swarms get bigger then subside again.

wolves speak!

Scientists studying grey wolves in Yellowstone national park have developed a method to predict how animals will respond to climate change.

“We now have the tools to determine how wolves would react to climate change,” said Tim Coulson, a professor of life sciences at Imperial College London, who led the study. “With any luck, in the future we can apply the methods developed from the wolves down to small mites or to large herbivores.”

The study used data that is already routinely collected on radio-collared wolves to get a glimpse of some basic responses to a changing environment – population numbers, genetics, body size, and the timing of key events in the wolf life cycle, such as when they first have pups.

Some animals will be constantly on the move, up hill and to cooler locations at a rate of about a quarter of a mile a year according to one study, in search of suitable homes. Other animals will run out of space, and die out. Still others may successfully adapt, growing bigger or smaller to suit their new conditions. The Guardian, 2 Dec 2011

plant trees!

………………………………….

Whether you plant trees around your home and property, in your community, or in our national forests, they help fight climate change.
Through the natural process of photosynthesis, trees absorb CO2 and other pollutant particulates, then store the carbon and emit pure oxygen.
See how planting trees helps fight climate change.

don’t plant trees!

A new study, however, published in Proceedings of the National Academy of Sciences reports that forests’ other climatic effects can cancel out their carbon cleaning advantage in some parts of the world.

Using a three-dimensional climate model, the research team mimicked full global deforestation and also studied the effects of clear-cutting in different regions of latitude, such as the tropics and boreal zones.

Apparently, these natural carbon sinks only do their job effectively in tropical regions; in other areas, they have either no impact or actually contribute to warming the planet. In fact, according to this model, by the year 2100, if all the forests were cut and left to rot, the annual global mean temperature would decrease by more than 0.5 degree Fahrenheit.

“I’m not sure the slight amount of cooling is necessarily significant, but that removing all the forest produced little change” on temperature is, says study co-author Ken Caldeira, an ecologist at the Carnegie Institution of Washington’s Department of Global Ecology in Stanford, Calif.

“I think what’s interesting is this global cancellation was a product of very different responses at different latitudes.”

warning against light green

Some 35 million Americans regularly buy products that claim to be earth-friendly, according to one report, everything from organic beeswax lipstick from the west Zambian rain forest to Toyota Priuses.

With baby steps, more and more shoppers browse among the 60,000 products available under Home Depot’s new Eco Options program. But even at this moment of high visibility and impact for environmental activists, a splinter wing of the movement has begun to critique what it sometimes calls “light greens.”

“There is a very common mind-set right now which holds that all that we’re going to need to do to avert the large-scale planetary catastrophes upon us is make slightly different shopping decisions,” said Alex Steffen, the executive editor of Worldchanging.com, a Web site devoted to sustainability issues.

The genuine solution, he and other critics say, is to significantly reduce one’s consumption of goods and resources. It’s not enough to build a vacation home of recycled lumber; the real way to reduce one’s carbon footprint is to only own one home.

Venice opens and shuts

Will Venice really disappear within 100 years? If nothing is done to stop the encroaching sea, then yes.

The problem that Venice faces is familiar to anyone living along the Thames estuary – the land is sinking while, thanks to global climate change, the sea is rising.

“It’s a city that lies at sea level so it’s very vulnerable to changes,” says Caroline Fletcher, an environmental chemist and the Venice research fellow at Cambridge University, who is running the conference. Without any action, she warns, the city will be uninhabitable by 2100.

Fortunately, the Italian government has marked Venice as a priority for action and is trialling one possible solution. The city is at one end of a lagoon with three openings to the Adriatic sea.

The Italian scientists are testing a mobile barrier that could move into place in these openings at high tide, thereby blocking out any surges of water during storms.

gardeners to the rescue!

As gardeners, we are both guardians and stewards of our environment, says Patty Glick, author of the report and Global Warming Specialist for the National Wildlife Federation. “There are many simple and thoughtful ways we can manage our gardens that can make an enormous difference in reducing the impacts of global warming.”

Gardeners can play an important role in minimizing the threat of invasive species expansion by removing invasive plants from the garden and choosing an array of native alternatives. Establish a “green roof” and plant trees around your house.

Planting rooftop gardens and planting trees near your home can significantly shield your home from the elements, reducing energy use for air conditioning in the summer and heating in the winter. There are a number of ways to reduce water consumption in your garden, which will be particularly important when water resources become scarce.

Actions that can help include mulching, installing rain barrels, watering only in the morning and evening to avoid mid-day evaporation and using drip irrigation.

(Don’t) Feed The Man Meat!

A report by Chatham House, “Changing Climate, Changing Diets: Pathways to Lower Meat Consumption,” released in late November, identifies the world’s appetite for meat as a major driver of climate change and concludes that a worldwide shift to healthier, more plant-based diets could bring about a 25% reduction in the gap between current global emissions plans and what is needed to prevent “dangerous” climate change.

“As governments look for strategies to close the Paris emissions gap quickly and cheaply, dietary change should be high on the list,” says Laura Wellesley, an author of the seminal report.

ban clean air!

It may seem counterintuitive, but cleaner air could actually be exacerbating global warming trends. The soot and other particles that make up air pollution tend to scatter light back out into space.

As countries around the globe have cleaned up their act, there are fewer particles to reflect light, meaning more sunlight is reaching the Earth’s surface and warming it, Martin Wild, a researcher at ETH Zurich in Switzerland, said Tuesday (Dec. 15) here at the annual meeting of the American Geophysical Union.

weeds on the move!

A recent CSIRO report for the Australian Government’s Land and Water Australia looked at what effects climate changes anticipated for 2030 and 2070 might have on the distribution of 41 weeds that pose a threat to agriculture (“sleeper” species) and the natural environment (“alert” species).

“We found that climate change will cause most of these weeds to shift south, with wet tropical species making the greatest move – over 1000km,” CSIRO researcher, Dr John Scott said.

“The predicted move south by both native and introduced plants would produce a ‘vacuum’ in northern Australia so, to prevent lurking species from invading, a new list of alert and sleeper weeds for this region needs to be developed,” Dr Scott said. Science Daily, 16 Apr 2009

but I thought….

The world’s dams are contributing millions of tonnes of harmful greenhouse gases and spurring on global warming, according to a US environmental agency.

International Rivers Network executive director Patrick McCully told Brisbane’s Riversymposium rotting vegetation and fish found in dams produced surprising amounts of methane – 25 times stronger than carbon dioxide.

Often it’s accepted that hydropower is a climate friendly technology but in fact probably all reservoirs around the world emit greenhouse gases and some of them, especially some of the ones in the tropics, emit very high quantities of greenhouse gases even comparable to, in some cases even much worse than, fossil fuels like coal and gas,” Mr McCully said.

head for the hills! – soon!

A study done by non-profit research organization Climate Central shows that even a seemingly minor temperature rise – 3.6 degrees Fahrenheit – on Earth will result in submerged cities around the world, and they’ve got the pictures to prove it.

“Two degrees Celsius warming will pose a long-term, existential danger to many great coastal cities and regions,” lead author Ben Strauss, vice president for sea level and climate impacts at Climate Central, told AFP and explains that a four-degree spike would double the danger.

Although the increase in temperature would take place over the course of 200 years, the group’s research says it’s more likely that these striking scenes wouldn’t actually occur for another 2,000 years.

nature refuses to co-operate!

Global warming activists stormed Washington Monday for what was billed as the nation’s largest act of civil disobedience to fight climate change — only to see the nation’s capital virtually shut down by a major winter storm.

Schools and businesses were shuttered, lawmakers cancelled numerous appearances and the city came to a virtual standstill as Washington was blasted with its heaviest snowfall of the winter.

One protester named Kat had planned to get arrested and be bailed out Monday but decided to stay put and donate her money to a good cause instead.

“I don’t want to travel in the snow today. However, I am donating my bail money to fight mountaintop removal,” she wrote to the Climate Action Web site.
