The folly, egoism and dangers of climate geo-engineering

Administrator’s note: It’s my pleasure to feature a guest essay by Glen Barry. Dr. Barry is founder and President of Ecological Internet; provider of the largest, most used environmental portals on the Internet including the Climate Ark and EcoEarth.info. A conservation biologist and political ecologist, he writes impassioned, thought provoking essays from an uncompromising ecological point of view. They appear regularly on his blog, Earth Meanders, where this one originated.

In this essay, Dr. Barry takes a strong stance against geo-engineered solutions to climate change. This is a contentious topic on which respected scientists and environmentalists hold a wide range of opinions. Glen’s essay prompts us to think hard about fundamental questions such a topic raises, questions concerning the role of humans in the global ecology. My thanks to Glen for making it available. — JF

By Glen Barry:

Is humanity so resistant to change that we will tamper with the biosphere’s workings to construct a “Frankensphere” rather than reducing population, consumption and emissions?

phytoplankton bloomIt is being widely suggested that humanity can “geo-engineer” a global solution to climate change; that is, modify the Earth’s biosphere at a planetary scale. Many methods are proposed. Most include either reflecting additional solar radiation away from the Earth, or using the ocean to store more carbon.

Reactionary geo-engineering proposals emerge largely from a sense of desperation as the world fails to rein in greenhouse gas emissions, and an unwillingness to make necessary societal and personal changes in response to deadly climate change. To some the extreme action of taking the Earth’s ecological systems into techno-human hands seems sensible given indications that global heating is proceeding more rapidly than thought, as shown by unexpectedly quick melting of Arctic sea ice.

Risky climate geo-engineering schemes include giant vertical pipes in the ocean to increase ocean circulation and thus marine carbon sequestration, similarly growing vast blooms of ocean plankton by fertilizing with iron, erecting giant mirrors above the earth to reflect the sun’s energy, and dropping sulfur particles from balloons at high altitude to do the same.

Two rogue US companies are moving forward with plans to fertilize the ocean with iron to create plankton blooms to suck heat-trapping carbon dioxide out of the atmosphere. They are motivated by profits from the growing carbon credit market, rising public demands for action, and politicians eager to avoid painful reductions in emissions. There is little that can be done to stop them, as no applicable laws or treaties exist. (more…)

Global warming: the great equaliser

Administrator’s note: It’s increasingly obvious that despite the gravity of the global ecological crisis, few governments are undertaking anything approaching the actions that might prevent catastrophe. In this article, Adam Parsons makes clear the gap between the form and level of economic change needed to address climate change and the reality of the inaction we see today. Yet he sounds a hopeful note in observing the potential for global warming to become the issue which finally prompts a new examination and restructuring of the global, market based economic system.

Global warming mapBy Adam W. Parsons:

As the latest summit to discuss a post-Kyoto treaty continues in New York this week, the single most revealing statement has already been spoken: “We need to climate-proof economic growth”. These few words, told to reporters by the UN’s top climate official, Yvo de Boer, during the recent Vienna round of talks, define the blinded establishment approach to tackling climate change.[1] Only if continued trade liberalisation and corporate profits are kept sacrosanct, remains the assumption, is it possible to consider even a broad agreement on future cuts in greenhouse-gas emissions.

With dire weather events and studies being reported on an almost daily basis, fewer sceptics are able to dismiss the reality of dangerous climate change. In the same week as around 1,000 diplomats, scientists, business leaders and environmental activists from 158 countries attended the U.N.’s Vienna Climate Change Talks, a top security think-tank stated that climate change could have global security implications “on a par with nuclear war unless urgent action is taken”,[2] whilst leading scientists warned of a looming “global food crisis” that will require more food to be produced over the next 50 years than has been produced during the past 10,000 years combined.[3]

The rapidity of these dystopian predictions has grown to Faustian proportions; the year 2007 already has the dubious accolade of witnessing the most extreme weather events on record,[4] as characterised by the millions of Africans just hit by some of the worst floods in a generation in which villagers were “wiped off the map”.[5] This summer, the collapse of the Arctic ice cap (losing a third of its ice since measurements began 30 years ago and “stunning” experts)[6] was topped off by the latest UN study from the Intergovernmental Panel on Climate Change (IPCC) who now believe that the tipping point for widespread catastrophe – involving a two degrees rise in global temperatures – is “very unlikely” to be avoided.[7] (more…)

When environmental writers are part of the problem

Note: The article below has appeared in several online publications. Though its roots were in an earlier GIM piece, it’s a rather different essay. I hope GIM readers who haven’t previously navigated to it through the link in the Off-site Articles section will find it worth a read.

In recent months there have been signs that some concerned about global sustainability are beginning to recognize once again that population size and growth must have a central place in any discussion of our ecological dilemma. Avoidance of the topic continues, though, among environmentalists who might otherwise raise awareness of the nature of the environmental challenges ahead. With that in mind, here’s a look at how environmental writers are sometimes part of the problem. — JF

Avoiding the truth

By John Feeney:

Something’s missing in today’s environmental discussion. When talking about causes and proposed solutions for our ecological plight, few environmental writers are telling us more than half the story. Al Bartlett, physics professor emeritus at the University of Colorado and long time sustainability activist calls it “the silent lie.” It’s the near universal tendency to focus on the importance of cutting fossil fuel use while staying mum on the topic of population growth.

John Holdren, last year’s president of the American Association for the Advancement of Science, told us the whole story over a decade ago in an article titled, “Population and the Energy Problem.” In it, he observed that the total energy consumption for a country or the world, is the product of population size multiplied by the average per capita energy use. Today, the developers of the “ecological footprint” measure, William Rees and Mathis Wackernagle, echo Holdren when they explain:

[The ecological footprint] for the world as a whole is the product of population times per capita consumption, and reflects both the level of consumption and the efficiency with which resources are turned into consumption products.

Funny but true

We spend a lot of time here on topics far from laughable. Time for a brief break from that – at least from the “far from laughable” part. A while back, George Meyer, a writer for The Simpsons TV show, produced the following piece for the BBC’s Green Room. It’s the only article I can remember reading which zeros in accurately on aspects of our global environmental plight and makes me laugh. It also calls for everyone, even crazy Michael Chricton, to become an environmentalist. Enjoy:

Welcoming Homer the tree-hugger

Are you a hypocrite? Because I certainly am.

I’m an animal lover who wears leather shoes; a vegetarian who can’t resist smoked salmon. I badger my friends to see the Al Gore movie, but I also fly on fuel-gulping jets.

Great clouds of hypocrisy swirl around me.

Climate change is just a symptom

Administrator’s note: Time for another article from a guest contributor. Jerry West describes himself as “editor/publisher/janitor” for The Record, an independent, progressive newspaper in Gold River, British Columbia. He’s a columnist, as well, for the well known Canadian progressive news site, rabble.ca.

A number of his articles would fit well with the content on GIM. But this one stood out during a week when I’ve been preoccupied with the stubborn tendency of both policy makers and mainstream environmentalists to turn a blind eye to the fundamental drivers of our ecological crisis. It’s a constant problem in coverage of climate change. Well meaning environmental writers, their thinking apparently numbed by the peer pressure of groupthink, tell us we can solve climate change — which they see as an isolated environmental problem — with routine economic tweaks or perhaps a switch to fluorescent bulbs.

Jerry is a writer who sees past that superficiality, and this article, which originally appeared in The Record, is one result. My thanks to Jerry for his permission to post it. – JF

Jerry WestBy Jerry West:

The BC government has committed itself to reduce BC’s greenhouse gas emissions by 33 per cent by the year 2020. The questions remain — is it enough, and will they have the fortitude to take the actions necessary and to provide the funds to do it.

In Britain Parliament is considering reducing the UK’s emissions by 50 per cent by the year 2050 and some argue that 80 per cent is a more reasonable figure. One thing is certain, climate change has come front and centre as a political issue, and governments of all stripes are scrambling to find ways to make it look like they are dealing with it. One suspects that “make it look like” is the main purpose for them.

Climate change is an issue for us, but it is only a symptom of a much bigger problem. Humans are stripping the resources of the planet faster than they can be replenished; like aggressive cancer cells we are consuming our host. Since the amount of resources are limited the only cure for this is to consume less of them.

There are two ways to do this: one is individually which means quality of life for most of us in developed countries goes down considerably, and continues to go down as populations increase. Or, we can do it collectively by reducing population to a level that there is more than enough for everybody. (more…)

Impressions of The 11th Hour

The 11th HourBy John Feeney:

I had the chance last night to see an advance screening of Leonardo DiCaprio’s new film, The 11th Hour, a documentary about our environmental crisis and what we can do about it. I had the good fortune of going with Dave Gardner, founder of Save The Springs, one of the most progressive urban growth control groups in the US. Dave is also a film maker by profession, and is working on his own related documentary, Choking on Growth: Our Misguided Quest for Prosperity.

Not great, but…

The 11th Hour uses snippets of interviews with a variety of experts to highlight several of the key facets of the ecological decline with which we’re faced. It also provides a vision of an ideal, waste free, renewable energy future, and some consideration of the mindset which got us into this mess.

It’s a good, but not great documentary, in part because it lacks the intellectual honesty to touch more than momentarily on population growth despite the scientific consensus concerning its central role in our ecological plight. This is no surprise; it’s in line with most environmental discussion in today’s media. (more…)

Kudos to Chris Rapley!

Chris Rapley, head of the British Antarctic Survey and now the new head of Britain’s Science Museum, has lately been one of the leading voices calling for action to halt population growth. He’s raised the issue in discussions of climate change. A quick article in the Guardian has his latest comments. This stands out:

The crucial point is that to achieve this goal [of lowering birthrates to halt population growth sooner than it might otherwise stabilize] you would only have to spend a fraction of the money that will be needed to bring about technological fixes, new nuclear power plants or renewable energy plants. However, everyone has decided, quietly, to ignore the issue.

Rapley is a big enough name that he’s able to get the population issue into the news and has done so repeatedly. I first spotted him calling attention to it in an article on the BBC website in January of ’06. Later, I heard he’d pushed the topic in a talk about climate change. Then came another article a month ago, and now the one above.

I can’t think of another public figure as prominent as Rapley who’s been as persistent of late on the subject of population. He deserves the most positive recognition for that. Hats off to Chris Rapley!
