Carbon Life: Bacteria to President Barack Obama
Life survives miles below the Earth’s surface
By Stephen Leahy
UXBRIDGE, Canada, Mar 5 2013 (IPS)
Every living thing from bacteria to President Barack Obama is made of carbon from exploding stars.
Billions of years ago, motes of carbon and other stardust formed the Earth. Carbon is the basis of all life but most vanished deep inside the planet, researchers now believe. And surprisingly, life thrives inside the rocky layers kilometres below our feet.
“Microbes survive by eating rock at those depths,” said Robert Hazen, executive director of the , a decade-long, global collaboration investigating the inner workings of the planet.
“Life is very different under those tremendous pressures and temperatures,” Hazen told IPS.
The variety of bacterial life at extreme high-pressure depths worldwide constitutes a subterranean “Galapagos”, he said. There may be as much as half of all life in the ground deep below us, according to one estimate, although Hazen thinks that might be too high.
“Drill a hole one or two kilometres deep just about anywhere and you will find a sparse but hardy microbial community,” said Isabelle Daniel of l’Université Claude Bernard in Lyon, France.
“These deep microbes, which live in the tiniest cracks and fissures in rocks, survive on the chemical energy of minerals,” said Daniel, who is one hundreds of scientists involved in the Deep Carbon Observatory (DCO).
DNA analysis reveals a diversity of microorganisms, mainly single-celled. However, deep below the ocean floor live fungi-like organisms with complex cell structures. Researchers estimate that these are extraordinarily long-living organisms, conceivably living for millions of years.
“There are also a huge numbers of viruses, their DNA carefully inserted into living cells,” said Hazen.
“We Should be Shaking in Our Boots” – UN Environment Official
Earth’s Ability to Support Us At Risk – An Indictment of Governments We Elected
By Stephen Leahy
RIO DE JANEIRO, Jun 19 2012 (IPS)
The science is crystal clear: humans are threatening Earth’s ability to support mankind, and a new world economy is urgently needed to prevent irreversible decline, said scientists and other experts at an event on the sidelines of the Rio+20 Earth Summit.
Yet the Global Environment Outlook report, or GEO 5, which was launched on June 6 and assessed 90 of the most important environmental objectives, found that significant progress had been made only in four in the 20 years since the first landmark summit in Rio in 1992.
Achim Steiner, the executive director of the United Nations Environment Programme (UNEP) said the results of GEO 5 were “depressing, even to me”.
“This ought to have us shaking in our boots,” Steiner told TerraViva at the Fair Ideas conference that concluded Sunday. ”It is an indictment of our behaviour over the past 20 years and of the governments we elected. We need an honest conversation about why we are not turning things around.”
Instead, “what’s happening right now in the RioCentro (Rio+20 official site) is that science is being picked out of the text of the final agreement,” Johan Rockström, executive director of the Stockholm Resilience Centre in Sweden, told the conference.
Rockström said he had received updates from the negotiations that the United States and some of the world’s least developed countries were attacking the science showing humanity is pushing up against “planetary boundaries”.
Climate is only one of those “planetary boundaries”. Another is the ongoing decline of biodiversity, where so many plants and animals are going extinct that the Earth’s living systems, upon which humanity depends, are unravelling. Fresh water is another planetary boundary. Water is a limited resource, yet water use has increased six-fold in the past century.
“The science is absolutely clear: we are up against the edges of the planet’s ability to support us and approaching irreversible tipping points,” Rockström said. Read the rest of this entry »
Concrete Sustainable Development Goals the Only Recipe for Success
How to Secure a Viable Future for All
By Stephen Leahy
RIO DE JANEIRO, Jun 16 (TerraViva)
Goals drive action, and that’s why establishing a set of Sustainable Development Goals is so important to put the world on a sustainable pathway, experts said Saturday under the tropical fig and palm forest that covers much of the ground at the Pontifical Catholic University of Rio de Janeiro.
“Building a consensus on a set of goals will give the world community clarity about what needs to be done and a way to measure progress,” said Saleemul Huq, a senior fellow in the Climate Change Group at the International Institute of Environment and Development (IIED).
Terms like “green economy” and “sustainability” have too many different meanings and too many different interpretations, Huq told TerraViva during a break at the two-day Fair Ideas conference organised by IIED and the Pontifical Catholic University.
The Millennium Development Goals (MDGs) have proven to be a useful tool even though some will not be achieved by the 2015 deadline, he said. The MDGs helped guide governments in setting their policies to try to meet the targets such as reducing poverty by half. The MDG target of having the number of people without access to safe drinking water was met early this year.
The MDGs have no environmental focus and they only applied to the developing world, Huq said.
“Sustainable Development Goals would be much broader covering pollution, environment impacts and consumption and apply to all countries rich and poor but in different ways.”

The governments of Colombia and Guatemala first proposed a framework for establishing Sustainable Development Goals (SDGs) be one of the main outcomes at the Rio+20 Summit on Sustainable Development.
“The SDGs are not about the environment, they are about securing a viable future for all people,” said Paula Caballero, director of economic, social and environmental affairs, Ministerio de Relaciones Exteriores of Colombia.
“We need the public and policy makers to understand this,” Caballero told the conference. Read the rest of this entry »

Low Carbon, Green Only Way Out of Poverty Trap
RIO DE JANEIRO, Jun 15 (TerraViva)
Poor countries that green their economies will lift millions of their citizens out of poverty and generate higher incomes while protecting invaluable natural ecosystems, says a report released here in Rio Thursday.
Some developing countries are actively pursuing a transition towards low-carbon, resource-efficient economies, it found.
“Our message is that economy and ecology can be brought together for the greater benefit of all people, but especially the poorest,” said Peter Hazlewood, director of Ecosystems and Development at the World Resources Institute (WRI), and co-author of the report “Building an Inclusive Green Economy for All”.
“This transition will not be easy. It will require new policies, targeted investments and reforms of government institutions,” Hazlewood said.
Governmental departments like agriculture, environment and economic development that rarely talk to each other will have to be integrated and learn to work together, he told TerraViva.
“If we can’t get this right, we will be in big trouble,” Hazlewood warned. Read the rest of this entry »
Voice of Youth Ignored by Governments
Taking away the voice of the next generation
By Stephen Leahy
RIO DE JANEIRO, Jun 17 (TerraViva)
Youth and future generations do not deserve a voice in their own future, the Brazilian government appears to have arbitrarily decided here at the Rio+20 Conference on Sustainable Development, where the theme is “The Future We Want”.
Representatives of children and youth, as well as the European Union and other countries, want to see the summit conclude with an agreement to create a High-Level Representative for Sustainable Development and Future Generations.
However, Brazil, under its formal leadership of the summit, has deleted all references to this from the “outcome document” currently under negotiation.
It is a bit surprising considering 62 percent of Brazil’s 185 million people are under 29 years of age.
The proposed representative for future generations would act to balance the short-term nature of government electoral cycles by advocating for the interests and needs of future generations, says youth representative Alice Vincent of the World Future Council Foundation in London, UK.
“I strongly believe that a Rio+20 outcome that does not include the creation of such an advocate for the needs of future generations wouldn’t be worthy of the title The Future We Want,” Vincent told TerraViva.
Over the past weeks there has been little progress on agreement of the content for the final 20-page “outcome document” intended to serve as the world’s roadmap to sustainable development. It will include details for greening of the global economy and possibly include sustainable development goals and a timetable for reaching them.
Countries were essentially deadlocked over the contents, so the Brazilian government revised the document and presented it to countries this morning saying it is an attempt to “make all delegates a bit happy, and a bit unhappy”. Read the rest of this entry »
Protecting Rights of Future Generations – The Injustice of Climate Change
Who will speak for future generations?
By Stephen Leahy
UXBRIDGE, Canada, Jun 5, 2012 (Tierramérica)
The theme of the United Nations Conference on Sustainable Development (Rio+20) is “The Future We Want”, but there is no official role for youth nor a spokesperson for future generations who will inherit that futur
Now there is a growing call for the creation of a United Nations High Commissioner for Future Generations to be one of the outcomes of the summit, which will take place Jun. 20-22 in Rio de Janeiro, Brazil.
“I was born in 1992, the year of the first Earth Summit in Rio. The world has changed a lot since then,” says Vincent Wong of Burlington, Canada.
Wong will be going to Rio+20 as part of a delegation from Students on Ice, a Canadian organisation that offers educational expeditions to the Arctic and Antarctic for students, educators and scientists.
“We want to bring the voice of our generation. They will be making decisions on our behalf,” Wong told Tierramérica.
“Who can be opposed to protecting the rights of future generations?” asks Alice Vincent of the World Future Council (WFC) in London, UK.
“The proposed High Commissioner for Future Generations would act to balance the short-term nature of government electoral cycles by advocating for the interests and needs of future generations,” Vincent told Tierramérica.
According to Kathleen Dean Moore, distinguished professor of philosophy at Oregon State University, “The injustice of climate change, resource depletion, etc. is that those who will suffer the most terrible consequences – future generations – had no role in creating them.”
“They will gain nothing from the ransacking of the Earth that is going on all around us, but they will bear the consequences: the floods, the droughts, the disrupted food systems, shortages, and violent weather,” Moore told Tierramérica.
“A U.N. Commissioner for Future Generations can stand up against the unjust treatment of those not yet born, which future generations, of course, cannot do for themselves,” she added. Read the rest of this entry »
24 Policies That Can End Our Earth Emergency
“Ecological literacy is vital for those in positions of power and influence”
Never vote for anyone who isn’t literate
By Stephen Leahy
UXBRIDGE, Canada, Jun 7 2012 (IPS)
Ecologically ignorant policies are largely responsible for the interlinked crises that are unraveling the planet’s life support system.
The unintended consequences of such policies are climate change, desertification, biodiversity decline, ocean pollution and the destruction of forests, according to the policy advocacy organisation World Future Council.
The solution is to eliminate “bad” policies and implement policies that ensure a healthy planet for future generations. On world environment Day, Jun. 5, the World Future Council will present an emergency policy agenda consisting of 24 tipping-point policies that need to be implemented globally to preserve a habitable planet.
“We are in an Earth Emergency. It’s an unbelievable crisis. Policies are the most important tool we have to change this,” Jakob von Uexkull, founder and chair of the World Future Council (WFC).
The five-year old WFC is based in Hamburg, Germany and comprised of 50 eminent individual from around the globe who have already successfully promoted change.
“Policy may be seen as dull and boring but they are the things that shape our societies,” von Uexkull told IPS.
In 2000, the German government created the now famous feed-in tariff policy launching a renewable energy revolution. That policy has enabled Germany to generate 22 percent of its electricity from renewables today and created a new business sector employing more people than its automotive industry.
“With the best laws and right policy incentives we can mobilise human inventiveness and entrepreneurship to safeguard a healthy planet for future generations,” he said.
On the other hand bad government policies allow 3,000 of the world’s biggest corporations to escape more than 2.2 trillion dollars in annual costs through their impacts on the natural environment, according to the U.N. Environment Programme. (A trillion is one thousand billion. A trillion seconds is nearly 32,000 years). Read the rest of this entry »
“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 »
Fossil Energy Interests Buy Politicians – and they’re cheap says economist
[This interview with economist Robert Repetto (now at Yale) was published two years ago. It is more relevant than ever in showing how fossil fuel money influences politics and prevents real action on climate. -- Stephen]
‘What else can you do with coal except burn it? Railways make a lot of money shipping coal’
By Stephen Leahy
UXBRIDGE, Canada, Mar 2, 2011 (IPS)
Powerful fossil energy interests are preventing the United States from making the necessary transition to 21st century energy sources, one of the country’s leading environmental economists documents in a just-published book.
Fossil energy interests are spending “hundreds of millions of dollars” lobbying U.S. politicians in Congress and funding groups to confuse the public about the serious risks climate change poses, says Robert Repetto, author of “America’s Climate Problem: The Way Forward”.
IPS climate and environment correspondent Stephen Leahy spoke with Repetto about his new book.
Q: Why did you write this book?
A: We’re running out of time. The latest science shows that climate change is coming faster and posing greater risks than previously thought. We are at risk of triggering positive feedbacks that will lead to uncontrollable climate change.
Meanwhile, America is locked in a climate-policy stalemate, with very few in the public comprehending the real risks climate change poses. Most don’t understand that climate change is happening now. They don’t link extreme weather events we’ve been experiencing with climate change. As a result they are not demanding that politicians take action.
Q: Why don’t most Americans understand the fact that climate change is already underway and poses serious risks? Read the rest of this entry »
The Most Important Number in Human History
Carbon overload Carbon in atmosphere and amount in fossil fuel reserves
That number was 52 billion tonnes of CO2 in 2012
Only when this number declines will we know we’re making the shift to climate protection
By Stephen Leahy
UXBRIDGE, Canada, Dec 17 2012 (IPS)
The most important number in history is now the annual measure of carbon emissions. That number reveals humanity’s steady billion-tonne by billion-tonne march to the edge of the carbon cliff, beyond which scientists warn lies a fateful fall to catastrophic climate change.
With the global total of climate-disrupting emissions likely to come in at around 52 gigatonnes (billion metric tonnes) this year, we’re already at the edge, according to new research.
To have a good chance of staying below two degrees C of warming, global emissions should be between 41 and 47 gigatonnes (Gt) by 2020, said Joeri Rogelj, a climate scientist at Switzerland’s Institute for Atmospheric and Climate Science in Zurich.
“Only when we see the annual global emissions total decline will we know we’re making the shift to climate protection,” Rogelj told IPS.
Making the shift to a future climate with less than two degrees C of warming is doable and not that expensive if total emissions peak in the next few years and fall into the 41-47 Gt “sweet spot” by 2020, Rogelj and colleagues show in their detailed analysis published Sunday in the journal Nature Climate Change.
The study is the first to comprehensively quantify the costs and risks of emissions surpassing critical thresholds by 2020. Read the rest of this entry »
