“We’re all scared…But we must tell the truth” — Experts Fear Collapse of Global Civilisation
By Stephen Leahy
UXBRIDGE, Canada, Jan 11 2013 (IPS)
Experts on the health of our planet are terrified of the future. They can clearly see the coming collapse of global civilisation from an array of interconnected environmental problems.
“We’re all scared,” said Paul Ehrlich, president of the Center for Conservation Biology at Stanford University.
“But we must tell the truth about what’s happening and challenge people to do something to prevent it,” Ehrlich told IPS.
Global collapse of human civilisation seems likely, write Ehrlich and his partner Anne Ehrlich in the prestigious science journal, Proceedings of the Royal Society.
This collapse will take the form of a “…gradual breakdown because famines, epidemics and resource shortages cause a disintegration of central control within nations, in concert with disruptions of trade and conflicts over increasingly scarce necessities”, they write.
Already two billion people are hungry today. Food production is humanity’s biggest industry and is already being affected by climate and other environmental problems. “No civilisation can avoid collapse if it fails to feed its population,” the authors say.
Escalating climate disruption, ocean acidification, oceanic dead zones, depletion of groundwater and extinctions of plants and animals are the main drivers of the coming collapse, they write in their peer-reviewed article “Can a collapse of global civilisation be avoided?” published this week.
Dozens of earth systems experts were consulted in writing the 10-page paper that contains over 160 references.
“We talked to many of the world’s leading experts to reflect what is really happening,” said Ehrlich, who is an eminent biologist and winner of many scientific awards.
Our reality is that current overconsumption of natural resources and the resulting damage to life-sustaining services nature provides means we need another half of a planet to keeping going. And that’s if all seven billion remain at their current living standards, the Ehrlichs write.
If everyone lived like a U.S. citizen, another four or five planets would be needed. Read the rest of this entry »
Nuclear Energy and the ‘Mother of all Subsidies’
[The two year anniversary of the Fukushima nuclear disaster is March 11. Little has changed from this 2011 article (except cleanup costs may be higher at $250 billion). Generations of Japanese taxpayers will have to cover those costs. Other countries also have liability caps which means the public provides 'free insurance' to the industry. As this article shows it'd be cheaper to give interest-free loans to solar or wind industry. -- Stephen.]
“…it is basically insanity to shoulder the public with risk to get relatively small amount of electricity…”

UXBRIDGE, Canada, May 6, 2011 (IPS)
The nuclear energy industry only exists thanks to what insurance experts call the “mother of all subsidies”, and the public is largely unaware that every nuclear power plant in the world has a strict cap on how much the industry might have to pay out in case of an accident.
In Canada, this liability cap is an astonishingly low 75 million dollars. In India, it is 110 million dollars and in Britain 220 million dollars. If there is an accident, governments – i.e. the public – are on the hook for all costs exceeding those caps.
Japan has a higher liability cap of 1.2 billion dollars, but that is not nearly enough for the estimated 25 to 150 billion dollars in decommissioning and liability costs for what is still an ongoing disaster at its Fukushima Daiichi nuclear plant. Seven weeks after the tsunami caused the disaster, radiation levels continued to spike higher.
No one knows when the reactors will finally be in cold shutdown, or when the costs of the Fukushima disaster will stop piling up. One report suggests decommissioning will take 30 years.

Japan’s credit rating was downgraded because of the accident, noted Mycle Schneider, a Paris-based energy and nuclear policy analyst who has worked in Japan. “The Japanese know it’s just a matter of time before another large earthquake occurs,” Schneider told IPS.
“Japan will never build another nuclear plant.“

Canada and US Spending Billions to Create Climate Chaos
Welcome to Bizarro World

Analysis by Stephen Leahy
UXBRIDGE, Canada, Aug 10, 2011 (IPS)
Canada and the United States are now the centre of Bizarro World. This is where leaders promise to reduce carbon emissions but ensure a new, supersized oil pipeline called Keystone XL is built, guaranteeing further expansion of the Alberta tar sands that produce the world’s most carbon-laden oil.
“It’s imperative that we move quickly to alternate forms of energy – and that we leave the tar sands in the ground,” the U.S.’s leading climate scientists urged President Barack Obama in an open letter Aug. 3.
“As scientists… we can say categorically that it’s [the Keystone XL pipeline] not only not in the national interest, it’s also not in the planet’s best interest.”
The letter was signed by 20 world-renowned scientists, including NASA’s James Hansen, Ken Caldeira of the Carnegie Institution, Ralph Keeling of the Scripps Institution of Oceanography, and George Woodwell, founder of the Woods Hole Research Center Read the rest of this entry »
Green Energy Solves Dual Crises of Poverty and Climate
Dirty fossil fuel energy leads to 350,000 premature deaths in Europe
By Stephen Leahy
UXBRIDGE, Canada, Feb 25 2013 (IPS)
Green energy is the only way to bring billions of people out of energy poverty and prevent a climate disaster, a new study reveals.
Conservative institutions like the World Bank, the International Energy Agency and accounting giant Price Waterhouse Coopers (PwC) all warn humanity is on a path to climate catastrophe unless fossil fuel energy is replaced by green energy.
The U.N.’s Sustainable Energy for All initiative intends to bring universal access to modern energy, doubling the share of renewable energy globally, and doubling the rate of improvement in energy efficiency by 2030.
If those targets are met and similar efforts undertaken to reduce deforestation, then climate disaster can be avoided, said Joeri Rogelj of the Institute for Atmospheric and Climate Science in Zurich who headed the analysis published Sunday in the journal Nature Climate Change.
“Poverty eradication, sustainable development and the transition away from fossil fuel energy go hand in hand,” Rogelj told IPS. Read the rest of this entry »
Jail Before Climate-Wrecking Tar Sands, Canadians Say
Tar sands protest Sept 2011, Ottawa Pic by R Leahy

OTTAWA, Sep 27, 2011 (IPS)
More than 200 Canadians engaged in civil disobedience, with 117 arrested in Canada’s quiet capital city on Monday. The reason? To protest the Stephen Harper right-wing government’s open support for the oil industry and expanding production in the climate-disrupting tar sands.
The normally placid and polite Canadians shouted, waved banners and demanded the closure of the multi-billion-dollar tar sands oil extraction projects in northern Alberta to protect the global climate and the health of local people and environment.
“People are here because they know that if we don’t turn away from the tar sands and fossil fuels soon it will be too late,” Peter McHugh, a spokesperson for Greenpeace Canada, told IPS.
“The tar sands are unsustainable. Canadians are willing to shift away from fossil fuels but our government isn’t,” Gabby Ackett a university student and protester, told IPS as she stood in front of a long line of police.
In what was proudly touted as “civil” civil disobedience, protesters aged 19 to 84 were arrested for using a step-stool to climb a low barrier separating them from the House of Commons, the seat of Canadian government. The police were friendly and accommodating because the organisers had promised there would be no violence.
“We live downstream and see the affects of tar sands pollution on the fish and the birds,” said George Poitras, a former chief of the Mikisew Cree First Nation in northern Alberta.
“Some our young people have rare forms of cancer,” Poitras told more than 500 protesters.
“Expanding the tar sands is not the way to go in a world struggling with climate change,” he said. Read the rest of this entry »
US Climate Rally Draws “Line in the Sand” on Keystone Pipeline

UXBRIDGE, Canada, Feb 16 2013 (IPS)
The largest climate rally in U.S. history is expected Sunday in Washington DC with the aim of pressuring President Barack Obama to reject the Keystone XL tar sands pipeline.
Activists are calling Keystone “the line in the sand” regarding dangerous climate change, prompting the Sierra Club to suspend its 120-year ban on civil disobedience. The group’s executive director, Michael Brune, was arrested in front of the White House during a small protest against Keystone on Wednesday.
“The Keystone XL pipeline is part of the carbon infrastructure that will take us to dangerous levels of climate change,” said Simon Donner, a climate scientist at the University of British Columbia.
“By itself, Keystone won’t have much of an impact on the climate, but it is not happening on its own,” Donner told IPS.
Carbon emissions are increasing elsewhere, and the International Energy Agency recently warned humanity is on a dangerous path to four degrees C of warming before the end of this century. Children born today will experience this. Preventing that dire future is inconsistent with expanding tar sands production, Donner said.
A new study released this week revealed that the volume of Arctic sea ice is declining rapidly. Ice volume has fallen 80 percent since 1980, according to the latest data from European Space Agency satellite, CryoSat-2. Summers with a sea ice-free Arctic are only a few years away, scientists now agree. This will have significant and permanent impacts on weather patterns in the Northern Hemisphere.
“Keystone XL is the key to opening up the expansion of the tar sands industry,” said Jim Murphy, senior counsel with the National Wildlife Federation.
“By rejecting the Keystone XL tar sands pipeline, we can keep this toxic oil in the ground,” Murphy said in a statement.

After Hurricane Sandy swept through the northeast of the United States late October 2012, millions of New Yorkers were left for days without electricity. But they still had access to drinking water, thanks to New York City’s reliance on protected watershed areas for potable water.
Instead of using electric-powered water treatment plans, New York City brings its high-quality drinking water through aqueducts connected to protected areas in the nearby Catskill/Delaware forests and wetlands – just one example of how protecting watersheds can provide residential areas with drinking water and flood and pollution protection at bargain basement prices.
New York saved between four and six billion dollars on the cost of water treatment plants by protecting forests and compensating farmers in the Catskills for reducing pollution in lakes and streams.
In 2011, countries around the world invested more than eight billion dollars in similar watershed projects around the world, according to the State of Watershed Payments 2012 report released Thursday. That year, China led the way, accounting for 91 percent of watershed investment.
“Whether you need to save water-starved China from economic ruin or protect drinking water for New York City, investing in natural resources is emerging as the most cost-efficient and effective way to secure clean water and recharge our dangerously depleted streams and aquifers,” said Michael Jenkins, president of Forest Trends, a non-governmental organisation (NGO) in the United States, which compiled the report.

Worlds’ Scientists Say Facing “Planetary Emergency”
Planet Under Pressure – State of the Planet Declaration Mar 29 2012.
By Stephen Leahy
UXBRIDGE, Canada, (IPS)
[Based on my article Climate Summit: A Moment That Must Be Seized ]
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.
“Planetary emergency” is how many in the world’s scientific community describe “the mess we are in“. They will detail their comprehensive state of the planet assessment at the “Planet Under Pressure” conference in London Mar. 26-29.
That assessment will summarise the overwhelming evidence that “the continued functioning of the Earth system as we know it is at risk,” conference organisers previously told IPS.
Climate change, which is overheating the planet and making the oceans more acidic, is just one of the major challenges. Another is the ongoing decline of biodiversity, where so many plants and animals are going extinct that the Earth’s living systems on which humanity depends are unraveling.
Fresh water is another “planetary boundary” humanity is pushing up against. Water use has increased six-fold in the past century and in many places the quality of water resources has been degraded. Other challenges include increasing poverty, food and energy security, and the current financial and economic instability.
A first and essential step in a green transition is for nations to commit to phasing out harmful and unsustainable subsidies for fossil fuels, fisheries and industrial agriculture.
According to Mooney, some countries and large corporations see the green economy in terms of a post-petroleum future where resources and energy for industrial production comes from biomass and other living things. Most of those “living resources” are in the global South and local people rightly fear a massive land grab, he said.
Foreign investors have already gained access to more than 35 million hectares in Africa, Asia and South America for food and biofuel production according to GRAIN, a small NGO working with small farmers and farming communities.
Hothouse Needed for Green Energy, Green Ideas Revolution

Countries cannot afford to miss the green wave of Rio+20
No alternative to low-carbon, resource-efficient economies
By Stephen Leahy
UXBRIDGE, Canada, May 25, 2012 (IPS)
Think of Rio+20 as the hothouse to grow the green ideas and values humanity needs to thrive in the 21st century.
No one is expecting, or even wants, a big new international treaty on sustainable development said Manish Bapna, interim president of the World Resources Institute, a global environmental think tank based in Washington, D.C.
“The important action will be on the sidelines of the formal negotiations,” Bapna told IPS in an interview.
Blocs of countries, civil society organisations and representatives of business will meet, create coalitions and make commitments on specific issues and on regional concerns.
“There could be some exciting specific commitments coming out of Rio,” Bapna said.
Perhaps the most important outcome from Rio+20 would be to put to rest the erroneous belief that protecting the environment comes at the cost of economic growth when it is in fact the opposite. Without a healthy, functioning environment, humanity loses the benefits of the environment’s “free products”: air, water, soil to grow food, stable climate and so on.
“One of the big hurdles to a sustainable future is that officials in many countries think they can’t afford to move onto a more sustainable pathway,” he said.
Bapna hopes Rio+20 will generate a “new narrative” – a wider understanding that there is no viable alternative to the transition to low-carbon, resource-efficient economies that alleviate poverty and create more jobs. Read the rest of this entry »
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.
