Earth’s Attic Is On Fire: Arctic Sea Ice Bottoms Out At New Record Low

The extraordinary decline in Arctic sea ice during 2012 is finally over. Sea ice extent bottomed out on September 16, announced scientists at the National Snow and Ice Data Center (NSIDC) on Wednesday. The sea ice extent fell to 3.41 million square kilometers, breaking the previous all-time low set in 2007 by 18%–despite the fact that this year’s weather was cloudier and cooler than in 2007. Nearly half (49%) of the icecap was gone during this year’s minimum, compared to the average minimum for the years 1979 – 2000.

 

This is an area approximately 43% of the size of the Contiguous United States. And, for the fifth consecutive year–and fifth time in recorded history — ice-free navigation was possible in the Arctic along the coast of Canada (the Northwest Passage), and along the coast of Russia (the Northeast Passage or Northern Sea Route.)

 

“We are now in uncharted territory,” said NSIDC Director Mark Serreze. “While we’ve long known that as the planet warms up, changes would be seen first and be most pronounced in the Arctic, few of us were prepared for how rapidly the changes would actually occur. While lots of people talk about opening of the Northwest Passage through the Canadian Arctic islands and the Northern Sea Route along the Russian coast, twenty years from now from now in August you might be able to take a ship right across the Arctic Ocean.”….

 

Commentary: Earth’s attic is on fire

To me, seeing the record Arctic sea ice loss of 2012 is like discovering a growing fire burning in Earth’s attic. It is an emergency that requires immediate urgent attention. If you remove an area of sea ice 43% the size of the Contiguous U.S. from the ocean, it is guaranteed to have a significant impact on weather and climate. The extra heat and moisture added to the atmosphere as a result of all that open water over the pole may already be altering jet stream patterns in fall and winter, bringing an increase in extreme weather events. This year’s record sea ice loss also contributed to an unprecedented melting event in Greenland. Continued sea ice loss will further increase melting from Greenland, contributing to sea level rise and storm surge damages. Global warming doubters tell us to pay attention to Earth’s basement–the Antarctic–pointing out (incorrectly) that there is no fire burning there. But shouldn’t we be paying attention to the steadily growing fire in our attic? The house all of humanity lives on is on fire. The fire is certain to spread, since we’ve ignored it for too long. It is capable of becoming a raging fire that will burn down our house, crippling civilization, unless we take swift and urgent action to combat it.

Forest Fire Research Questions the Wisdom of Prescribed Burns

By JIM ROBBINS New York Times Published: September 17, 2012

MISSOULA, Mont. — On a forested mountainside that was charred in a wildfire in 2003, Richard Hutto, a University of Montana ornithologist, plays a recording of a black-backed woodpecker drumming on a tree. The distinctive tattoo goes unanswered until Dr. Hutto is ready to leave. Then, at the top of a tree burned to charcoal, a woodpecker with black feathers, a white breast and a yellow slash on its crown hammers a rhythmic response. This forest may have burned,” says Dr. Hutto, smiling, “but that doesn’t mean it’s dead. There’s a lot going on.” The black-backed woodpecker’s drum signals more than the return of life to the forest. It also may be an important clue toward resolving a debate about how much, and even whether, to try to prevent large forest fires. Scientists are at loggerheads over whether there is an ecological advantage to thinning forests and using prescribed fire to reduce fuel for subsequent fires — or whether those methods actually diminish ecological processes and biodiversity. The United States Forest Service, which manages nearly 200 million acres of public land, believes limited thinning and burning will prevent catastrophic wildfires. The agency contracts with logging companies to cut down large and small trees across sweeping landscapes, and uses prescribed fire. Besides protecting homes, experts say, these methods also recreate the natural state of the forest. The approach, developed primarily as a result of tree ring studies, seeks to reconstruct the forests of the West before the 20th century, when the large-scale suppression of wildfire first occurred. Some ecologists and environmentalists, however, are challenging the Forest Service’s model, saying it is based on incomplete science and is causing ecological damage.

Recent research, they say, shows that nature often caused far more severe fires than tree ring records show. That means the ecology of Western forests depends on fires of varying degrees of severity, including what we think of as catastrophic fires, not just the kinds of low-intensity blazes that current Forest Service policy favors. They say that large fires, far from destroying forests, can be a shot of adrenaline that stimulates biodiversity. ….

Protecting ecosystems brings benefits to society
(September 17, 2012)Ecosystems are essential to our well-being and prosperity as they provide us with food, clean air and fresh water. Ecosystems also represent an exceptional source of outdoor recreation opportunities. The functions performed by ecosystems that increase our well-being are called ecosystem services. The PEER Research on EcoSystem Services (PRESS) initiative describes how different EU policies can help to increase the services and benefits provided by ecosystems, and calls for the inclusion of the ecosystem services approach into European policy measures affecting the use or state of natural resources…

… The first phase of the study, which was concluded in September 2011 with the publication of a first PRESS report, demonstrated methodologies to map the role of ecosystems as providers of clean water and recreation and investigated how ecosystem services can be mainstreamed into agriculture, fisheries or forestry policies. The second and final phase of the study consisted of case studies carried out on pollination, recreation and water purification to explore how assessment methods to measure and map ecosystem services might be developed at multiple spatial scales….Synthesis report is intended to convey four main policy messages:

 

Scientists study fungus to defeat cheatgrass
September 06, 2012 12:11 am  •  Jeff Delong – Reno Gazette-Journal RENO, Nev. — At Skull Valley, they study the black fingers of death.These scientists aren’t mad, and this isn’t a B-grade horror flick. Rather, researchers with the U.S. Forest Service’s Rocky Mountain Research Station are closely examining a fungus that has potential to help control the spread of cheatgrass, an invading plant spreading across millions of acres of the Great Basin at alarming cost to its ecology. The fungus’ catchy moniker came from the tiny, hair-like filaments that emerge from cheatgrass seeds after it attacks. “After it kills the seed it sticks these black things out that look like fingers,” Susan Meyer, research ecologist said.”It goes into them and eats them alive, basically,” Meyer said. “It looks like a horror movie. It really does.”It’s the black fingers of death doing their thing.…..Cheatgrass, native to the steppes of Eurasia, was introduced to America through contaminated seed in the 1890s. It was first found in Nevada in 1906 and now dominates roughly 20 million acres of the West, Meyer said. Cheatgrass invades and dominates the landscape, taking over terrain where sagebrush and native grasses thrive naturally. It often dominates land charred by wildfire and, once established, the highly flammable grass is prone to fuel future fires in a damaging cycle….

 

 

Invisible Plastic Particles in Seawater Damaging to Sea Animals

September 20, 2012Plastic nanoparticles in seawater can have an adverse effect on sea organisms. Particles measuring about a thirty millionth of a millimetre, and therefore invisible to the naked eye, are responsible. Mussels that have been exposed to such particles eat less, and thus grow less well, according to research carried out by scientists and students at Wageningen University and IMARES, both part of Wageningen UR. They wrote about their research in the most recent issue of Environmental Toxicology and Chemistry. The presence of ‘plastic soup’ in the oceans is regarded as a big problem. Tiny plastic particles enter the sea when plastic debris decomposes. Such particles are probably also released from cosmetics and from clothes in the wash, subsequently entering the sewage system and surface waters and eventually reaching the sea.

Aldo Leopold’s Field Notes Score a Lost ‘Soundscape’

ScienceDaily (Sep. 18, 2012) —Rising before daylight and perched on a bench at his Sauk County shack in Depression-era Wisconsin, Leopold routinely took notes on the dawn chorus of birds. Beginning with the first pre-dawn calls of the indigo bunting or robin, Leopold would jot down in tidy script the bird songs he heard, when he heard them, and details such as the light level when they first sang. He also mapped the territories of the birds near his shack, so he knew where the songs originated. Among his many qualities, the pioneering wildlife ecologist Aldo Leopold was a meticulous taker of field notes. Lacking a tape recorder, the detailed written record was the best the iconic naturalist could do. “Leopold took amazing field notes,” says Stan Temple, a University of Wisconsin-Madison emeritus professor of wildlife ecology and now a senior fellow of the Aldo Leopold Foundation. “He recorded his observations of nature in great detail.” …..”The difference between 1940 and 2012 is overwhelmingly the anthrophony — human-generated noise,” explains Temple. “That’s the big change. In Leopold’s day there was much less of that.”

The resurrected soundscape of 1940s Sauk County is the first to be recreated from actual data rather than someone’s imagination of what the past sounded like, says Temple. The work fits into an emerging field of science known as soundscape ecology, which seeks to explain the role of sound within a landscape and how it influences the animals — birds, insects, amphibians, even fish — that live there.…..Preserving the natural sounds of a place, avers Temple, may be just as challenging as conserving the mosaic of plants and animals that help keep an ecosystem intact. Like smell and sight, “sound can be what you associate with a particular landscape,” something Leopold appreciated and wrote about in several of his well known essays. By noting and studying the role of sound in the natural world, Leopold proved again to be ahead of his time. Science is only now coming to grips with the totality of the sounds of nature (much like the sound of an entire orchestra) rather than the individual components of the soundscape, according to Temple. Understanding how nature’s “music” is changing and how much attention we need to pay to the sounds introduced by people, he says, are challenges for soundscape ecologists. And we have much to learn about what the noise people make does to the environment….

Climate Change Dramatically Increases Rainfall in the Tropics

Laboratory Equipment – September 18, 2012‎

Global warming is expected to intensify extreme precipitation, but the rate at which it does so in the tropics has remained unclear. Now an MIT study has given an estimate based on model simulations and observations: with every 1 C rise in temperature, the study finds, tropical regions will see 10 percent heavier rainfall extremes, with possible impacts for flooding in populous regions…..”Unfortunately, the results of the study suggest a relatively high sensitivity of tropical extreme rainfall to global warming,” O’Gorman says. “But they also provide an estimate of what that sensitivity is, which should be of practical value for planning.” The results of the study are in line with scientists’ current understanding of how global warming affects rainfall, says Richard Allan, an associate professor of climate science at the Univ. of Reading in England. A warming climate, he says, adds more water vapor to the atmosphere, fueling more intense storm systems. “However, it is important to note that computer projections indicate that although the rainfall increases in the wettest regions — or similarly, the wet season — the drier parts of the tropics… will become drier still,” Allan says. “So policymakers may have to plan for more damaging flooding, but also less reliable rains from year to year.”

 

Warming Ocean Could Start Big Shift of Antarctic Ice

ScienceDaily (Sep. 19, 2012) — Fast-flowing and narrow glaciers have the potential to trigger massive changes in the Antarctic ice sheet and contribute to rapid ice-sheet decay and sea-level rise, a new study has found. Research results published in the journal Proceedings of the National Academy of Sciences reveal in more detail than ever before how warming waters in the Southern Ocean are connected intimately with the movement of massive ice-sheets deep in the Antarctic interior.

“It has long been known that narrow glaciers on the edge of the Antarctica act as discrete arteries termed ice streams, draining the interior of the ice sheet,” says Dr Chris Fogwill, an author of the study and an ARC Future Fellow with the UNSW Climate Change Research Centre. “However, our results have confirmed recent observations suggesting that ocean warming can trigger increased flow of ice through these narrow corridors. This can cause inland sectors of the ice-sheet — some larger than the state of Victoria — to become thinner and flow faster.”…. The glaciers that responded most rapidly to warming oceans were found in the Weddell Sea, the Admundsen Sea, the central Ross Sea and in the Amery Trough. “To get a sense of the scale, the Antarctic ice sheet is 3km deep … and it extends across an area that is equivalent to the distance between Perth and Sydney. Despite its potential impact, Antarctica’s effect on future sea level was not fully included in the last IPCC report because there was insufficient information about the behavior of the ice sheet. This research changes that. This new, high-resolution modelling approach will be critical to improving future predictions of Antarctica’s contribution to sea level over the coming century and beyond.”

Major Changes Needed to Protect Australia’s Species and Ecosystems

ScienceDaily (Sep. 18, 2012)A landmark study has found that climate change is likely to have a major impact on Australia’s plants, animals and ecosystems that will present significant challenges to the conservation of Australia’s biodiversity. The comprehensive study by CSIRO highlights the sensitivity of Australia’s species and ecosystems to climate change, and the need for new ways of thinking about biodiversity conservation.

“Climate change is likely to start to transform some of Australia’s natural landscapes by 2030,” lead researcher, CSIRO’s Dr Michael Dunlop said.

“By 2070, the ecological impacts are likely to be very significant and widespread. Many of the environments our plants and animals currently exist in will disappear from the continent. Our grandchildren are likely to experience landscapes that are very different to the ones we have known.”

Dr Dunlop said climate change will magnify existing threats to biodiversity, such as habitat clearing, water extraction and invasive species. Future climate-driven changes in other sectors, such as agriculture, water supply and electricity supply, could add yet more pressure on species and ecosystems.

The study suggests the Australian community and scientists need to start a rethink of what it means to conserve biodiversity, as managing threatened species and stopping ecological change becomes increasingly difficult.”We need to give biodiversity the greatest opportunity to adapt naturally in a changing and variable environment rather than trying to prevent ecological change,” Dr Dunlop said.

The study highlights the need to start focusing more on maintaining the health of ecosystems as they change in response to climate change, from one type of ecosystem to another.

‘This could need new expectations from the community, possibly new directions in conservation policy, and new science to guide management,” Dr Dunlop said.

To be effective we also need flexible strategies that can be implemented well ahead of the large-scale ecological change. It will probably be too late to respond once the ecological change is clearly apparent and widespread.” The study found the National Reserve System will continue to be an effective conservation tool under climate change, but conserving habitat on private land will be increasingly important to help species and ecosystems adapt.

Report: The implications of climate change for biodiversity conservation and the National Reserve System: Final synthesis (pdf – 2.07mb)

 

From the Report:

–Page 40: In summary, in recognition that some losses of biodiversity values are inevitable, there is potentially merit in reducing the management focus on the most vulnerable parts of biodiversity. Such a move would have technical, administrative and social implications. Attempting to do this species-by-species would require considerable amounts of information. An alternative might be to use management approaches that can be demonstrated to be effective for many species, if not the most vulnerable, without necessarily needing to assess the vulnerability and management needs of individual species. Such approaches might focus on ecological processes, locations, biodiversity patterns, ecosystems and landscapes more than on individual species (Prober and Dunlop 2011).=

–Page 43: Adaptive management is a type of reactive strategy, or if implemented “actively” it has proactive elements (testing different strategies); either way, a primary component is waiting and monitoring ecological change, then altering management in response. Thus, due to the protracted feedback and difficulty of detecting the impacts of management or climate change in a timely manner amid much variability, it is likely that adaptive management may not be effective for directly addressing climate change impacts in many situations. It may be better to think of adaptive management as a framework within which climate adaptation might be implemented (and improved) rather than regarding it as a solution to climate change in itself.

–Page 53: As discussed in Section 4.4, the nature of climate change—its timing, multiple types of change, variation and noise—mean that many important signals of ecological change will be hard to detect, and possibly not until it is too late to adequately respond. One way to increase the effectiveness of monitoring might be to use scenario planning to identify key uncertainties about environmental or ecological change and then develop and explore various management options for each scenario. Where the differences between scenarios are critical for management, hypotheses can be developed that distinguish between the scenarios, and research and monitoring can be designed to test the hypotheses and provide rapid guidance about future change and which management actions to implement.

–Page 59: Key knowledge gaps identified in the project include:

Establishing new alliances between science and conservation agencies would ensure research was focused on priority policy and management knowledge gaps, and help facilitate rapid flow of information into conservation agencies’ decision making.

 

Protected areas facilitate species’ range expansions

Thomas et al PNAS August 14 2012

Abstract: The benefits of protected areas (PAs) for biodiversity have been questioned in the context of climate change because PAs are static, whereas the distributions of species are dynamic. Current PAs may, however, continue to be important if they provide suitable locations for species to colonize at their leading-edge range boundaries, thereby enabling spread into new regions. Here, we present an empirical assessment of the role of PAs as targets for colonization during recent range expansions. Records from intensive surveys revealed that seven bird and butterfly species have colonized PAs 4.2 (median) times more frequently than expected from the availability of PAs in the landscapes colonized. Records of an additional 256 invertebrate species with less-intensive surveys supported these findings and showed that 98% of species are disproportionately associated with PAs in newly colonized parts of their ranges. Although colonizing species favor PAs in general, species vary greatly in their reliance on PAs, reflecting differences in the dependence of individual species on particular habitats and other conditions that are available only in PAs. These findings highlight the importance of current PAs for facilitating range expansions and show that a small subset of the landscape receives a high proportion of colonizations by range-expanding species.

Climate change threat more real to those with perceived personal experience: study By Misty Harris September 17, 2012 Calgary Herald

We have dramatically shrinking glaciers. We have compelling science. We have adorable polar bears treading water. But wouldn’t you know it, what really makes us fret over climate change is making it all about us. A new study has found that a feeling of “personally experiencing” global warming heightens people’s perception of risks related to the environmental phenomenon – and particularly those risks germane to where they live. Changes to the seasons, unusual weather, water levels, snowfall patterns and shifts related to plants and animals were among the most common signs cited by lay people…

Unfortunately for climatologists, the study – to appear in the journal Global Environmental Change – paints a grim picture.  Seventy-three per cent of people either weren’t sure if they had experienced global warming or said they hadn’t, echoing the 2010 survey in which 70 per cent of respondents nationwide claimed no personal experience with the phenomenon (“don’t know” wasn’t an option)….


Carbon dioxide from water pollution, as well as air pollution, may adversely impact oceans
ScienceDaily (Sep. 19, 2012) — Carbon dioxide (CO
2) released into the oceans as a result of water pollution by nutrients — a major source of this greenhouse gas that gets little public attention — is enhancing the unwanted changes in ocean acidity due to atmospheric increases in CO2. The changes may already be impacting commercial fish and shellfish populations, according to new data and model predictions published September 19 in ACS’s journal, Environmental Science & Technology. William G. Sunda and Wei-Jun Cai point out that atmospheric levels of CO2, the main greenhouse gas, have increased by about 40 percent since the Industrial Revolution due to the burning of fossil fuels and land-use changes. The oceans absorb about one-third of that CO2, which results in acidification from the formation of carbonic acid. However, pollution of ocean water with nutrient runoff from fertilizer, human and animal waste, and other sources also is adding CO2 via the biological breakdown of organic matter formed during algal blooms, which also depletes oxygen from the water. …
The model predicted that this process will interact synergistically with the acidification of seawater from rising atmospheric CO2 in seawater at intermediate to higher temperatures. Together, the two ocean processes are predicted to substantially increase the acidity of ocean waters, enough to potentially impact commercial fisheries in coastal regions receiving nutrient inputs, such as the northern Gulf of Mexico and Baltic Sea. Clams, oysters, scallops and mussels could be the most heavily impacted, the report indicates….full story

Climate Change and Fall Foliage: Not a Good Match

By Michael D. Lemonick
Published: September 19th, 2012

It’s admittedly not on a par with the direct threats posed by rising seas or melting icecaps or extreme weather, but with autumn now upon us, it’s worth noting that climate change could also affect the brilliant foliage that paints forests from the Ozarks to the Appalachians with vibrant color every fall. The damage isn’t just esthetic, either: national statistics are hard to come by, but officials in New Hampshire estimate that leaf-peeping tourists pump up the state economy by about $1 billion each year. The estimate is about the same for North Carolina, and if you project those revenues onto New York, Massachusetts, Vermont, Maine and other prime fall-foliage destinations, you’re talking about real money. This year, at least in some places, the money may not be flowing in. “I hope I’m wrong,” said Karl Niklas, a professor of plant biology at Cornell, in an interview, “but I just think it’s not going to be a great year in central New York….

Climate change threatens nature from coffee to Arctic fox-forum

By Alister Doyle

LILLEHAMMER, Norway | Wed Sep 19, 2012 11:45am EDT

(Reuters) – Climate change is a threat to everything from coffee plantations to Arctic foxes and even a moderate rise in world temperatures will be damaging for plants and animals in some regions, experts said on Wednesday.

Habitats such as coral reefs or the Arctic region were among the most vulnerable to global warming, scientists said at a conference in Lillehammer, south Norway, organized by the Global Biodiversity Information Facility (GBIF).

Almost 200 governments agreed in 2010 to a goal of limiting global warming to below 2 degrees Celsius (3.6 Fahrenheit) above pre-industrial times, seen as a threshold for dangerous changes such as droughts, floods, desertification and rising sea levels.

“At 2C you have impacts. The idea that 2C is a safe level doesn’t really hold up,” said Jeff Price, coordinator of the Wallace Initiative, an international group seeking to model the effects of climate change on 50,000 types of plant and animals.

“And when you start moving beyond 2C the impacts on biodiversity start rapidly increasing through much of the world,” he said. Greenhouse gases from burning fossil fuels are the main cause of warming, according to a U.N. scientific panel.

On Sept. 10, President Obama signed a new Executive Order (E.O.) into law, which migrates former programs, trusts, and planning council’s regarding Gulf Coast Restoration, into a new bureaucracy just days after new oil and ecological concerns spring up after the effects of hurricane Isaac. The timing of this new E.O. appears to coincide with two new events taking place in the Gulf region. First, after hurricane Isaac crashed onto New Orleans, and other regions of the Gulf Coast, oil balls and other remnants of the BP oil spill surfaced on beaches and coast lines all along the Southeast.

Putting SF Bay Area’s Water Source to a Vote

In November, San Francisco will vote on a measure that could ultimately lead to the draining and restoration of Hetch Hetchy Valley – and force the city to look elsewhere for most of its water. In 1913, Congress approved the construction of a dam and an eight-mile-long reservoir, called Hetch Hetchy, in the northwest corner of Yosemite National Park to supply cheap water to San Francisco. The Hetch Hetchy Reservoir submerged a valley often likened to Yosemite Valley in its grandeur.

Efforts To Save Dying Salton Sea Dry up at State Capitol

The Salton Sea is already slowly dying. An $8.9 billion preferred alternative for sea restoration was chosen by state Resources Secretary Mike Chrisman and submitted to the Legislature in 2007. It would have created miles of barriers to make the sea one-fifth of its current size, as well as creating shallow saline and marsh habitats. That plan, however, went nowhere in the Legislature. With nowhere near the billions of dollars needed for a Salton Sea fix available, and with little political will in Sacramento and Washington for a comprehensive restoration or mitigation project, local officials are left scrambling.

A Crop Dividend: Restored Bird Habitat in New Jersey
Farmers and wildlife advocates don’t often see eye to eye; each can look at a field and see widely divergent possibilities. Yet by encouraging farmers to plant fields of flowers, an innovative program in New Jersey is helping to finance the rehabilitation of wildlife areas for endangered species of birds. The crop is sunflowers, and sales of sunflower seeds, bagged and sold as birdseed by the New Jersey Audubon Society, have financed the conversion of a 70-acre tract of state-owned land into a grassland habitat.

In The ‘Crazy’ World Of Carbon Finance, Coal Now Qualifies For Emission Reduction Credits

Posted: 19 Sep 2012 09:30 AM PDT

A coal train, or a load of CDM carbon credits?

In a decision criticized as “unfortunate” and even “insane” by onlookers, the United Nations has decided that new coal plants are eligible for carbon credits under the Clean Development Mechanism (CDM). The CDM is a trading platform set up by the UN that allows developed countries to obtain verified emissions reduction credits through renewable energy, energy efficiency, power plant fuel switching, and sustainable transportation projects in developing countries in order to meet Kyoto Protocol targets. Now the UN has added coal to the list of eligible projects. Again.….

Mass slaughter of farm animals set to push food prices up 14%

The cost of feed has soared following the worst US drought in living memory. —Farmers who cannot afford feed ‘liquidating’ pig and cattle herds will drive food inflation to record high, says Rabobank report

Rupert Neate and Josephine Moulds
The Guardian, Tuesday 18 September 2012

The mass slaughter of millions of farm animals across the world is expected to push food prices to their highest ever levels. As well as hitting consumers’ pockets, the predicted 14% jump in food prices will also dash the Bank of England’s hopes of pushing inflation down to 2% by next year.

Farmers across the world have begun a mass slaughter of their pig and cattle herds because they cannot afford the cost of feed, which has soared following the worst US drought in living memory, according to a report published on Wednesday.

Seeking Innovative Conservation Ideas in Western North America
 
A private foundation is looking to support projects in western North America that break new ground, foster innovative conservation thinking, or work in areas that have received little attention. Successful projects would have significant potential impact, either directly by demonstrating important ecological benefits, or indirectly by pioneering new strategies that could be widely applicable in the conservation realm. Projects should be ambitious in scope and vision ($2-8 million), produce tangible, measurable, on-the-ground results within 3-5 years, and focus on key conservation issues. If research or planning is a significant component of the project, these must be supported by other funds. Sell them your idea today by submitting a brief description – (no more than 1 page) to: InnovativeConservation@gmail.com.

New policies by the government of South Australia on energy efficiency, renewable energy, sustainable transport, zero waste, organic waste composting, water efficiency, wastewater irrigation of crops, peri-urban agriculture, and reforestation have taken Adelaide to the forefront of eco-friendly urban development.

 

 

The Demonization Of Clean Tech: The Five Biggest Myths

Posted: 18 Sep 2012 12:17 PM PDT by Trevor Winnie, via Clean Edge

The case for technologies that harness renewable resources, improve efficiency, and reduce emissions has never been stronger, and the industry known as clean tech continues to grow at a staggering pace – global revenues for the “Big Three” sectors of wind power, solar PV, and biofuels hit $246.1 billion in 2011 after a decade of annual growth averaging more than 30 percent. But such an all-encompassing classification – spanning clean energy, advanced transportation, advanced materials, and clean water technologies – has lately made the industry an easy target for opposition, especially in the U.S., where divisive national politics have made pragmatism a rare commodity. As a longtime analyst at clean-tech research firm Clean Edge and contributor to the recently published book Clean Tech Nation (coauthored by Clean Edge colleagues Ron Pernick and Clint Wilder), I should be on the front lines defending the clean-tech moniker. But given the noticeable intensifying of false debates surrounding clean tech in the last year, it’s worth taking a moment to examine ways in which the industry’s far-reaching identity has opened the door to some misplaced antagonism…..

PBS False Balance Hour – What’s Up With That?

Posted on 20 September 2012 by dana1981 www.skepticalscience.com

We have previously criticized the mainstream media for favoring false balance over factually accurate scientific reporting when it comes to climate change.  In one of the worst examples of this unfortunate and counter-productive practice, the US Public Boadcasting Service (PBS), which is funded by both taxpayers and private donations, (for example, from the Koch brothers) aired a climate story on the PBS News Hour which began by featuring the Berkeley Earth Surface Temperature (BEST) project’s Richard Muller, “balanced” with a subsequent interview of contrarian blogger Anthony Watts.

Ultimately, Watts’ comments suffered from a double standard, dismissing Muller’s comments as not yet being supported by peer-reviewed research, but offering his own opinions despite the fact that they were not only unsupported, but even contradicted by Watts’ own peer-reviewed research.

Managing for resilience in the face of climate change: a scientific approach to targeted oyster restoration in San Francisco Bay and Elkhorn Slough, California

Our new project website is at http://www.oysters-and-climate.org.   We invite you to take a look at the new website, which provides information on the basic project components, key documents, and collaborative input from key end-users.  We welcome your ongoing questions, feedback and input; and we will be posting updates and new data as it is generated. This project builds upon native oyster restoration research at Elkhorn Slough and recommendations in the San Francisco Bay Subtidal Goals Report, and the new website is tiered from the Subtidal Goals (www.sfbaysubtidal.org). This project is characterizing stressor levels at multiple sites at two California estuaries (San Francisco Bay, Elkhorn Slough), assessing native oyster populations at these sites and connectivity between them, and examining impacts of individual and combined stressors in laboratory experiments. The goal is to improve sustainability of Olympia oyster restoration in the face of climate change by providing restoration planning tools. In particular, the tools will identify sites most likely to support sustainable restoration projects, and will indicate whether reduction of some existing stressors will enhance resilience to climate-related stressors.   A more detailed project description can be downloaded from: http://www.sfbaysubtidal.org/oysters_documentlinks.html

 

Hidden cams reveal Point Reyes’ wildlife haven

SF Chron September 16, 2012

In muted dawn light near Olema Creek at Point Reyes National Seashore, a bobcat slinked along the trail in stealth mode.
But a secret camera caught it in the act.

Later, a buck with 4×3 antlers took a drink from the stream. Then, after that, a coyote. Motion-activated wildlife cameras hidden at Point Reyes have captured more than 20 major species, from mountain lions to badgers, with many surprises along the way. The photos show that the Bay Area’s greatest park is more than a nature sanctuary for humans. It is a vast haven for wildlife. To identify each animal, look for caption just beneath the gallery. The 50-year anniversary of the park, 1962-2012, was Thursday, and most of the ongoing events commemorate the park’s epic status as a national treasure: A diverse landscape that spans from sea to mountaintops, landmarks like the Point Reyes Light and Arch Rock, and when rated against parks across the Bay Area’s nine counties, the most dynamic trail system, best hike-in and boat-in camps, best visitor center and most helpful rangers. And by the way, you can show up for free. Point Reyes also rivals Yosemite National Park and Prairie Creek Redwoods State Park as California’s best wildlife preserve. The park’s 71,000 acres spans many habitats, and in turn, that diversity supports an array of wildlife. The full story and the 10 best places to see wildlife at Point Reyes — and what you might see there — was published in  Sunday’s Chronicle at sfgate.com/outdoors.

 

 

Google Energy Use: Company Reveals Information To Show That Search Is Green

JONATHAN FAHEY   09/ 8/11 01:44 PM ET
