When the carbon dioxide absorbed by the oceans dissolves in seawater, carbonic acid is formed and calcium carbonate, vital for the formation of the skeletons and shells of many marine organisms, becomes scarcer.

MONTEREY, California, Oct 2 2012 (IPS) –

Climate change will ruin Chilean sea snails’ ability to sniff out and avoid their archenemy, a predatory crab, according to Chilean scientists who presented their findings at an international science symposium here.

Researchers from Australia also revealed that as the oceans become more and more acidic, some fish become hyperactive and confused, and move towards their predators instead of trying to escape.

“The conditions in oceans are changing 100 times faster than at any time in the past,” said Jean-Pierre Gattuso, a marine biologist with CNRS-INSU and the Laboratoire d’Océanographie de Villefranche in France.

Climate change is making oceans warmer and more acidic. “We are beginning to understand what will happen. I think we can expect the worst,” Gattuso told Tierramérica*.

Global Temperatures Rising on a Devastating Trajectory

Global temperatures are only 0.7C warmer — on pace for +4C!

By Stephen Leahy

UXBRIDGE, Canada, May 25, 2012 (IPS)

Climate-heating carbon emissions set a record high in 2011, in a 3.2 percent increase over the previous year, the International Energy Agency reported this week. The main reason for this dangerous increase is that governments are failing to implement policies to prevent catastrophic increases of global temperatures.

A new report released on the last days of international climate talks in Bonn, Germany this week reveals that the planet is heading to a temperature rise of at least 3.5 degrees Celsius, and likely more, according to the Climate Action Tracker (CAT), despite an international agreement to keep global temperature rise below two degrees Celsius.

Not only are pledges inadequate, but countries are unable to fulfill even those pledges, a new CAT analysis shows. CAT is a joint project of Dutch energy consulting organisation Ecofys, Germany’s Climate Analytics, and the Potsdam Institute for Climate Impact Research.

“When we compared the emission reduction pledges of countries like Brazil, Mexico and the U.S., we found they did not have the policies in place to meet those pledges,” said Niklas Höhne, director of energy and climate policy at Ecofys.

Höhne told IPS that they looked only at the policies of a few countries, but no country’s policies were enough to meet their targets. Continue reading →

Worlds’ Scientists Say Facing “Planetary Emergency”

By Stephen Leahy

UXBRIDGE, Canada, (IPS)

The upcoming Rio+20 conference has to be the moment in human history when the nations of the world come together to find ways to ensure the very survival of humanity, many science and environmental experts believe.

Except that governments, the media and the public aren’t paying attention to the “planetary emergency” unfolding around them. The situation is like firefighters yelling “fire” in crowded room and still no listens.

“The situation is absolutely desperate and yet there’s nothing on the front pages or on the agenda of world leaders,” said Pat Mooney, executive director of the ETC Group, an international environmental organisation based in Ottawa.

“The lack of attention is a tragedy,” said Mooney, who has 40 years experience in international environment and development issues.

Humanity is failing in its stewardship of the planet. An incredible 85 percent of the world’s oceans are in trouble, said Susan Lieberman, director of international policy at the Pew Environment Group, a U.S. organisation.

Rio+20 is a major opportunity to turn this around, Lieberman told IPS.

The Jun. 20-22 Rio+20 meet is timed to coincide with the 20th anniversary of 1992 Earth Summit in Rio de Janerio. The Earth Summit captured world attention, with leaders from most countries and some 10,000 media attending.

It gave birth to the most important environmental treaties on climate change, biodiversity and land degradation and desertification. World leaders also endorsed Agenda 21, a detailed blueprint on how nations can practice sustainable development.

Years of preparation went into the 1992 Summit, while only months have gone into Rio+20.

“There hasn’t been nearly enough preparation to be able to sign treaties,” said Lieberman. It’s been a struggle to get many governments like such as the US to focus on Rio+20 at all she said.

“Governments are not giving this opportunity enough importance given the mess we are in,” said Lisa Speer, director of the international oceans programme at the Natural Resources Defense Council, a U.S. NGO. Continue reading →

VANCOUVER, Canada, Feb 20, 2012 (IPS)

Humanity’s failure to halt the deepening planetary emergency of climate change, extinctions of species and overconsumption of resources is a failure of imagination and mistaken beliefs that we act rationally.

The path to a truly sustainable future is through the muddy waters of emotions, values, ethics and most importantly, imagination, said artists and social scientists at the American Academy for the Advancement of Science (AAAS) conference here in Vancouver, British Columbia.

“We don’t live in the real world but live only in the world we imagine,” said David Maggs, a concert pianist and Phd student at the Institute for Resources, Environment and Sustainability at the University of British Columbia (UBC).

Our perception of reality is filtered by our personal experiences and values. That’s why the “if we only knew better, we’d do better” education and communication paradigm isn’t working, Maggs said. The underlying assumption that a failure to become more sustainable is the result of a lack of information is flawed, he told attendees at what is the world’s largest general science meeting.

“We live in our heads. We live in storyland,” agrees John Robinson of UBC’s Institute for Resources, Environment and Sustainability.

“When we talk about sustainability we are talking about the future, how things could be. This is the landscape of imagination,” Robinson told IPS. “If we can’t imagine a better world we won’t get it.”

This imagining will be complex and difficult. Sustainability encompasses far more than just scientific facts – it also incorporates the idea of how we relate to nature and to ourselves, he said.

“We haven’t yet grasped the depth of changes that are coming.” Continue reading →

Fracking and Shale Gas Accelerating Global Warming

Stephen 1 Must Read, CANADA, CLIMATE CHANGE/GLOBAL WARMING, economics, Energy, global warming, News, Pollution and Toxics, Science/Tech , , , , , , , , , , ,

UPDATE Jan 2013:

Yet another study reveals fracking has a huge problem of gas leaks. Up to  9% of the gas pumped out of the ground leaks into the atmosphere according to a study by National Oceanic and Atmospheric Administration (NOAA) published in Nature this week. Natural gas (methane) is a powerful greenhouse gas. If these leaks are widespread, fracking is worse than burning coal, accelerating global warming.

In Jan 2012 I detailed new research in the article below showing that replacing coal with natural gas from fracking does little to fight climate change (see below). Now two studies published that since then make an even stronger case that fracking for natural gas is a HUGE MISTAKE:

From Nature: Air sampling reveals high emissions from gas field. Methane leaks during production may offset climate benefits of natural gas.

From Environmental Research Letters: New study demonstrates switching to natural gas is the path to climate disaster. What’s needed is an aggressive deployment of zero-carbon technologies and conservation. Joe Romm explains. — Stephen

Shale Gas Worse Than Coal Study Finds

By Stephen Leahy

UXBRIDGE, Canada, Jan 24, 2012 (IPS)

Hundreds of thousands of shale gas wells are being “fracked” in the United States and Canada, allowing large amounts of methane, a highly potent greenhouse gas, to escape into the atmosphere, new studies have shown.

Shale gas production results in 40 to 60 percent more global warming emissions than conventional gas, said Robert Howarth of Cornell University in New York State.

“Shale gas also has a larger greenhouse gas footprint than oil or coal over the short term,” said Howarth, co-author of a study called “Venting and Leaking of Methane from Shale Gas Development” to be published in the journal Climatic Change.

(Audio of news conference)http://of%20news%20conference

This latest study follows up on Howarth and colleagues’ controversial April 2011 paper that provided the first comprehensive analysis of greenhouse gas emissions from shale gas obtained by hydraulic fracturing. That study found that when gas wells are “fracked”, they leak large amounts of methane and pose a significant threat to the global climate.

“We stand by the conclusion of our 2011 research,” said Howarth.

That research undercuts the logic of energy sector claims that shale gas is a “bridge” to a low-carbon energy future. Those claims are based on the fact that natural gas (which is mainly methane) has half the carbon content of coal, and when burned for electricity it is more energy efficient than coal.

This independent  journalism depends on public support. Click here learn more.

However, those climate gains are more than negated by methane leaks both at the well during the fracking process (called flow-back), and through the gas delivery and distribution system. Howarth and colleagues estimate that between 3.6 and 7.9 percent of all shale gas produced leaks – called “fugitive emissions” – into the atmosphere, making it worse than burning coal or oil.

Toxic Electronic Waste Grows by 40 Million Tonnes a Year — Poisons Kids in Africa

‘Public largely unaware of the e-waste impacts on human health and environment’

By Stephen Leahy

UXBRIDGE, Canada, Nov 1, 2011 (IPS)

Mountains of hazardous waste grow by about 40 million tons every year. This waste, mostly from Europe and North America, is burned in developing countries like Ghana in a hazardous effort to recover valuable metals.

A children’s school in Accra, Ghana’s capital, was recently found to be contaminated by lead, cadmium and other health-threatening pollutants at levels over 50 times higher than risk-free levels. The school is located directly beside an informal electronic waste salvage site.

“Poor people in Africa cannot afford to process Europe’s or America’s electronic wastes,” said Ghanaian researcher Atiemo Sampson.

“Those wastes are poisoning our children,” Sampson told IPS from Accra.

Ghana does not regulate the importation and management of electronic waste, or e-waste. The government hopes to have rules in place next year, he said.

Sampson, a Ph.D. student at the University of Ghana, was involved in testing the school and other areas in Accra near the Agbogbloshie scrap metal site, where more than 100 people break apart and burn electronic trash by hand to obtain valuable metals like copper.

Schoolchildren as young as six years old work around bonfires of circuitry, plastic and other leftover high-tech trash, he said.

A nearby produce market, a church headquarters and a soccer field were similarly polluted, to varying degrees. The soil around the school site had measurements for lead 12 times higher than the levels at which intervention is required. Lead is acutely toxic to children and can permanently damage their growing brains and nervous systems, even at very low levels of exposure.

“We don’t know what the immediate health impacts are. We are hoping to test the children’s blood for contaminants but we have not secured the necessary funding,” Sampson said.

International shipments of electronic trash are outlawed by the Basel Convention. However, European and North American e-waste is often shipped as “electronics for reuse” or hidden with legitimate cargo.

“Fracking” for Shale Gas: The Bridge to Global Warming Disaster

Switching from coal to gas can increase global warming – NCAR

[UPDATE JAN 20 2012: New study published in journal Climatic Change shows large volumes of methane released during fracking]

By Stephen Leahy 

DURBAN, South Africa, Dec 5, 2011 (Tierramérica)

Hydraulic fracturing or “fracking” is being used to tap the last remaining natural gas deposits across large areas of the United States and western Canada, fueling continued dependence on hydrocarbons instead of a shift to genuinely clean energy sources to cool the planet.

Called shale gas, these deposits represent a new and enormous source of fossil fuel.

“Fracking is driving exploration and drilling all over the United States,” said Gwen Lachelt of the non-governmental organisation Earthworks’ Oil & Gas Accountability Project.

“The oil and gas industry is marching across America from Texas to North Dakota and from the east coast to California,” Lachelt told Tierramérica.

There may be as much as 23,427 billion cubic metres (bcm) in recoverable gas from U.S. shale formations, according to the Annual Energy Outlook 2011, released in April by the U.S. Energy Information Administration (EIA).

The United States will consume 650 bcm of natural gas this year, the EIA projected. Globally, it estimates reserves of “unconventional gas” – the oil and gas industry term for shale gas and coal bed methane – at 915,000 bcm, with 100,000 bcm in Latin America.

However, that estimate is already out of date due to developments in fracking technology and exploration. The EIA estimate of shale gas in the United States in 2009 was less than half the 2011 estimate.

Fracking uses horizontal drilling and hydraulic fracturing with high pressure water and chemicals to fracture gas-bearing shale rock.

Holes are drilled vertically as little as 100 metres and as much as 3,000 metres into the shale, and then horizontally 1,000 metres along the shale formation. Chemicals and large amounts of water are pumped underground at high enough pressure to fracture the shale, releasing the gas into the pipeline.

The “dash for gas” as the industry pundits like to say is being driven by potential exports to Asia and the mistaken belief that natural gas is the “transition fuel” from coal to a low-carbon economy.

It is true that natural gas is “cleaner” in that it releases about 40 to 45 percent less carbon dioxide than coal does to produce the same amount of energy.
However, gas from fracking has a higher carbon footprint because more energy is needed to get the gas and because methane leaks out.

Methane has 25 times the warming impact of carbon dioxide.

Switching from coal to gas as an energy source could result in increased global warming, not less, according to the study “Coal to Gas: The Influence of Methane Leakage”, released in September by the U.S. National Center for Atmospheric Research (NCAR).

This is mainly due to the methane leakage problem, which is common but unregulated.

Rich Countries Largely Live Off Financial Transactions

[Excerpts from my Dec 2010 article on how rich countries move money around and produce little while preventing green development in Africa  — Stephen]

“The world’s big economies are largely living off financial transactions which are unconnected to development,” warns Supachai Panitchpakdi, secretary-general of United Nations Conference on Trade and Development.

In a rejection of failed neoliberal economic policies, Panitchpakdi said strong national policies on investments, taxation, protection of local industries, including subsidies, and changes to less restrictive intellectual property regimes are what is needed to green economies in Africa and elsewhere.

“Green economic development underpins environmental protection, economic growth and development,” he said.

Here’s a startling fact based in a new energy study:

Cars are parked 22 hours a day on average yet world will have 2.5 billion cars in 2050

The costs of car ownership and travel are far higher than anyone realizes: a 100 km total trip costs between 65 and 80 dollars when parking, fuel, wear and tear, insurance, depreciation, repairs are included. A car is usually parked and unused 22 hours a day but still incurs costs. Why not let someone use the car when you’re not and make some money at the same time Robin Chase told me for this article. She’s launched Buzzcar in France as part of a strategy for reducing carbon emissions and congestion in cities.   — Stephen

Why do car owners get so much more public space than bus riders, bicyclists or walkers?

By Stephen Leahy

BERLIN, Jun 2, 2011 (IPS)

The world’s more than 850 million cars and small trucks are parked 20 to 22 hours a day. Why not use these vehicles more efficiently by letting other people drive them when the owners aren’t, asks Robin Chase, CEO of Buzzcar, a car- sharing network to be launched shortly in France.

“Sharing vehicles is much more efficient and represents a huge opportunity,” Chase told some 800 attendees from more than 50 countries at the OECD’s annual International Transport Forum (ITF) in Leipzig last week. The Forum is an intergovernmental organisation for the transport sector involving 52 different nations.

The ITF projects there will be three times as many cars – an eye-popping 2.5 billion – by 2050 according to its Transport Outlook 2011 report released at the meeting. Adding that many more vehicles in a sustainable way is an “extraordinary challenge”, said Jack Short, Secretary General of the ITF.

The vast majority of this growth will come from the developing countries since travel by passenger vehicle in a number of high-income countries has not increased, and even declined in some countries. Short acknowledged making such projections is risky because many factors such as lower economic growth, congestion in cities or new technologies will have an impact on levels of car ownership in future.

And the Transport Outlook report did not factor in the potential for car-sharing to offer personal mobility without car ownership.

Buzzcar is a car sharing service where car-owners in a city or town allow their idle cars to be used by other local citizens in exchange for getting about 70-75 per cent of the rental fee, Chase told IPS in an interview. Even when a car is parked it costs their owners money, she says. The average cost of owning and operating car is 8,000 to 12,000 dollars a year even if it sits parked 22 hours a day. (update: more like $9,000 to 14,000 according to auto clubs)

Buzzcar is an opportunity for car owners to get better value out of their vehicles and to help with ever- rising costs of car ownership. More importantly car sharing reduces the need for car ownership overall, she says.

Chase was a co-founder of Zipcar, a U.S.-based car-rental network with more than a half million members where people rent cars by the hour from easy-to-access neighbourhood lots or stations. Zipcar owns some 8,000 rental cars. She then went on to start GoLoco, a ride sharing company in which people pay to ride along with others in the network, and the drivers take a cut of the fees.
