“Humanity is facing major challenges…urgent actions are needed”

Can we act as a true community?

By Stephen Leahy

UXBRIDGE, Canada, Jan 11, 2012 (IPS)

Humanity is driving Earth’s climate and ecosystems towards dangerous tipping points, requiring radical new forms of international cooperation and governance, experts say.

“We’re facing a planetary emergency,” said Owen Gaffney of the International Geosphere-Biosphere Programme based in Stockholm.

“We need to have a ‘constitutional moment’ in world politics, akin to the major transformative shift in governance after 1945 that led to the establishment of the United Nations and numerous other international organisations,” said Frank Biermann of VU University Amsterdam and director of the Earth System Governance Project.

“Humanity is facing major challenges…urgent actions are needed,” Biermann told IPS.

Those challenges include, but are not limited to, increasing poverty, food, water and energy security, the financial crisis, climate change, ocean acidification, the loss of biodiversity. All of these challenges and their solutions are interconnected.

Normally, the complex, mutually dependent systems of the Earth can self-correct and are remarkably stable. However, they can reach thresholds or tipping points and then unexpectedly and abruptly shift, Gaffney said in an interview.

“We need only recall how the U.S. sub-prime mortgage crisis nearly collapsed the global financial system,” he said.

The upcoming Rio+20 conference on sustainable development needs 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”, he said. Continue reading →

A personal message from Stephen Leahy

“Journalism and media are society’s mirror providing accurate and essential information.

That is no longer the case.

Media are now controlled by a few major corporations like Murdoch’s News Corp. Coverage of environment and science has been gutted. If there is coverage it rarely digs below the surface. It’s not just TV, it’s all media.

After 18 years of being published in major publications on two continents I now count myself lucky to get $150 to $200 for an in-depth article. The few independent media outlets are either non-profits or struggling.

Urgent environmental issues didn’t go away just because most media stopped covering them.

More than 20,000 people attended the international climate meeting in Cancun, Mexico and it received one ten second clip on US network TV according to a Drexel University media study. (Coverage was even worse at last climate meet in Durban)

Nearly every indicator proves things are getting worse but less and less people know about this.

Many people, including leading scientists, tell me: ‘we need people like you to write about these issues‘. I’d like to do far more but it is impossible to continue without your help in what I’m calling Community Supported Journalism. People directly support independent journalists who craft honest and thoughtful articles about important subjects the mainstream media ignores or gloss over.

Community Supported Environmental Journalism Works

In 2010 dozens of people offered their help, donating $5,750 which helped ensure many breaking international stories were covered including the first media reports on the global die-off of corals and how climate change may be bringing colder winters to Europe and eastern North America. Those donors — I prefer to call them partners — enabled me to cover important international meetings like the UN Convention on Biodiversity, UNFCCC climate change conference and much more.

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.

Please throw something in the tip jar before reading on.

100,000 repetitions of a lie is still a lie

Many of those who deny that burning fossil fuels is altering the climate work diligently to confuse and delay action that would in reality benefit nearly all of us. These professional deniers and their followers can be convincing, citing well-known experts and twisting their views and findings.

So here’s a couple of common sense tips to add to your BS detection system.

Denier Tip #1:Check out suspect claims/sources with a simple Google search

100,000 repetitions or variations of a lie is still a lie. A reader recently told me global warming is really caused by variations in the sun’s activity. His proof was a “science” article from Investor’s Business Daily that said this was the conclusion of the Max Planck Institute for Solar System Research, a well-known research centre in Germany. A quick check of the Institute’s website…

Faith Groups Call for African Spirit of “Ubuntu”; End Sinful, American-style Greed

DURBAN, South Africa, Dec 9 (IPS)

African and international faith leaders urged governments attending the final day of climate change negotiations to do what is right and necessary to keep global temperature from rising no more than 1.5 degrees Celsius.

“The two degrees Celsius target is unacceptable because temperatures in much of Africa will be far higher,” said South African Bishop Geoff Davies.

Oil and coal companies along with other major polluting corporations are engaged in “crimes against humanity and the planet” because they continue to pollute the atmosphere when they have ability to do otherwise, said David Le Page of the Southern African Faith Communities’ Environment Institute (SAFCEI).

More than 130 African faith leaders have signed a declaration offering specific recommendations based science, honesty, morality and equity. They called on delegates negotiating a new climate treaty here at the 17th Conference of Parties to live up to the African spirit of “ubuntu” – a way of living focused on people’s allegiances and relations with each other.

The current economic system encourages “people to get as rich as they can and forget about anyone else,” said Davies. “It’s an immoral system.”

“Historic polluters like the United States have to reduce their emissions dramatically” and their position here is “shocking” and “reprehensible”, he said. The children and grandchildren of U.S. congressmen will ask what they were doing to be so selfish and irresponsible, Davies said.

The U.S is the most religious society in the world but their behaviour is “sinful” in their refusal to reduce emissions that causing so much suffering among people, he said.

“When lifestyles of the wealthy hurt the lives of the poor….and future generations it is wrong,” Mardi Tindal, Moderator of the United Church of Canada, the country’s largest Protestant denomination.

“Climate change is a moral, ethical and spiritual issue. We need moral leadership not political leadership,” Tindal told IPS.

“South Africa has had courageous, moral leaders like Ghandi and Mandela. If our leadership shows the same moral courage the people will follow them.” Continue reading →

A Very Inconvenient Truth: Gore Got It Right on Global Warming

[Reposted from 2006, nearly six years ago. It offers interesting perspective about the continuing (worsening?) political insanity of inaction  – Stephen]

By Stephen Leahy

BROOKLIN, Canada, Jun 20 (IPS)

Former U.S. Vice President Al Gore’s documentary on global warming, “An Inconvenient Truth”, is filling theatres across North America – and gets the science right, according to climate experts.

“I saw it last night and was impressed with the climate science presented in the film,” said David Archer, a climatologist at the University of Chicago.

“I left the theatre profoundly depressed because of the political insanity in this country that denies global warming is a concern,” Archer told IPS.

Gore’s personal passion about global warming can be traced to the early 1980s. After losing the election to George W. Bush in 2000, Gore dedicated himself to warning the public about the devastating impacts climate change will have on hundreds of millions of people.

“An Inconvenient Truth” is a 98-minute documentary comprised mainly of highlights from Gore’s high-tech slide show explaining the science documenting global climate change.

“Some truths are hard to hear, because if you really hear them – and understand that they are in fact true – then you have to change. And change can be quite inconvenient,” Gore says in the film.

Using an impressive set of graphics, he carefully illustrates changes underway such as receding glaciers, collapsing ice sheets, devastating floods and droughts. One memorable scene shows a graph of carbon-dioxide levels in the atmosphere going back 650,000 years that varies only a little until fifty years ago when it skyrockets. Gore mounts a motorised platform to lift him up high up the chart so he can place his finger on the current level of CO2. Continue reading →

No Time Left to Adapt to Melting Glaciers — Peak Water Has Already Come and Gone

Without sharp reductions in the use of fossil fuels, the impacts of climate change could come faster and beyond what humanity can adapt to — Lonnie Thompson, glaciologist

By Stephen Leahy

UXBRIDGE, Canada, Dec 27, 2011 (Tierramérica)

The water supplied by the glaciers of the Cordillera Blanca, vital to a huge region of northwest Peru, is decreasing 20 years sooner than expected, according to a new study.

Water flows from the region’s melting glaciers have already peaked and are in decline, Michel Baraer, a glaciologist at Canada’s McGill University, told Tierramérica. This is happening 20 to 30 years earlier than forecasted.

“Our study reveals that the glaciers feeding the Río Santa watershed are now too small to maintain past water flows. There will be less water, as much as 30 percent less during the dry season,” said Baraer, lead author of the study “Glacier Recession and Water Resources in Peru’s Cordillera Blanca”, published Dec. 22 in the Journal of Glaciology.

When glaciers begin to shrink in size, they generate “a transitory increase in runoff as they lose mass,” the study notes.

However, Baraer explained, the water flowing from a glacier eventually hits a plateau and from this point onwards there is a decrease in the discharge of melt water. “The decline is permanent. There is no going back.” Continue reading →

Oceans Becoming Hot, Sour and Breathless

Oceans home to 80% of all life — plankton provide 50 percent of the oxygen we breathe

By Stephen Leahy

DURBAN, South Africa, Dec 3 (IPS)

The world’s oceans are becoming hot, sour and breathless – threatening a vital source of food for a billion people mainly in the developing world experts warned today at a special Oceans Day event at the UN climate negotiation.

Oceans are home 80 percent of all life on the planet and emissions from fossil fuels are turning them increasingly acidic, raising water temperatures and reducing the amount of oxygen in some regions said oceanographer Carol Turley from Plymouth Marine Laboratory in the UK.

“We don’t know what all the consequences will be. We suspect the combination of all three will be far worse than one alone,” Turley told IPS in an interview on the sidelines of climate treaty negotiations known as COP 17.

It was only a few years ago that researchers realised that human emissions of carbon dioxide (CO2) was making the surface waters of oceans more acidic. The oceans naturally absorb CO2 from the atmosphere and have now absorbed about a third of all human emissions. That has kept the climate from warming faster but the additional carbon is altering the oceans’ chemistry making them 30 percent more acidic.

One documented impact is that shell-forming creatures like plankton produce thinner shells in more acidic ocean waters. These species are often very important parts of the marine food chain. As emissions of CO2 into the atmosphere increase the more the ocean sours.

[See a powerful 11 min film on Ocean acidification]

In less than ten years at least 10 per cent of the Arctic Ocean surface waters will be too acid for shell-forming species like plankton. By 2040 most of the Arctic Ocean will be too acidic as will significant areas of the Antarctic Ocean said Turley.

Change in sea water acidity pH caused by anthr...The cold waters of the polar regions allow more CO2 to be absorbed faster. The oceans haven’t seen a rapid change like this in 60 million years, she explained.

“But there will also be strange impacts. New research is showing changes in growth, behaviour and reproduction in a variety of non-shell forming species.”

Estuaries and ocean upwelling zones that are often important fishing grounds are also regions where acidification is fastest. Those areas are also subject to low oxygen levels and increasing temperatures creating new conditions in the oceans that no marine species has ever had to cope with.

Oceans are also absorbing most of the extra heat trapped by the additional CO2 in the atmosphere. Again, without this land temperatures would far higher and extreme weather events far worse.

“There is some evidence that some crab species cannot tolerate higher temperatures when ocean is more acidic,” she said.
