Some More Thoughts on Sustainability

After my last post on Sustainability, NPR ran this story with Susan Solomon, a leading climate scientist whose recent study indicates that global warming is for all practical purposes irreversible. As it turns out, like a giant reservoir the oceans have been absorbing heat and carbon as atmospheric levels continue to rise. If we were to stabilize carbon emissions, this absorption would continue. And if we are to reverse them, thereby bringing down the carbon levels in the atmosphere, the carbon and heat in the oceans will start to come out, polluting the atmosphere for us. The time frame of reversal appears to her to be in terms of 1000 years, instead of just 100 or 200, as we have been thinking. Most troubling is this quote.
If we continue with business as usual for even a few more decades, she says, those emissions could be enough to create permanent dust-bowl conditions in the U.S. Southwest and around the Mediterranean.
Since the whole debate surrounding even the idea of environmental sustainability has yet to have a clear vision, it seems to me that the conversation must include the potential and even likelihood of significant local difficulty. In which case our vision of how to prepare for, prevent and perhaps just adapt socially and economically to the future that awaits must include this possibility.

Capitalist systems and all western governments are built on the assumption that we have a ready and mostly trouble-free supply of food and water to feed our constituents. Imagine if that is significantly disrupted or destroyed. Imagine New York City, a city that at any one moment has enough food to feed its inhabitants for three days, if a massive environmental event were to take place disrupting it's food supply for significantly longer. What kind of picture does that start to make?

I should note that I am not advocating a fear based approach here, just a realistic one. We cannot control for all possible outcomes, but we can be better prepared should they arise. It seems likely that climate change will exert significant to dominant pressure on our culture over the next decades, increasing as time goes forward. Should it happen, this will be a very new thing for Americans. We live on the verdant continent of the world.

Some Thoughts On Sustainability

Anyone who reads this blog regularly knows that I keep coming back to the phenomenal ground of photography as an image-viewer interaction, rather than a viewer-subject interaction, the distinction being that it the image, not the subject, that the viewer actually encounters. I think this is incredibly important for the general audience to explore as we consume more and more pictures.

With that in mind, I want to draw your attention to Volume #18 which tackles the issue of sustainability, examining its philosophical and linguistic grounds with a mind to ask some hard questions about the difference between the green movement as a fantasy and the green movement as a pragmatic political reality. It is in the fantasy of the future that the concept achieves its own phenomenal ground.

Sustainability is the catch word of the year, even getting indirectly worked into President Obama's inaugural address. Climate change and environmental issues are being framed as the the next great challenge for humankind. And they are. According to Obama, we will be mobilizing our economy in a way that will tackle these issues head on, as a country and perhaps modeled after a war effort. But...
From After Zero, by Arjen Oosterman

Indeed, a clear differentiation between making a future and the possible making of the future is important. Architecture is called to arms to rescue the world from extinction, or rather humankind from perdition. Architecture is expected to vanquish a giant with many names, to free the way to the 'future.' What this future should be is rarely discussed. Nor has the true nature of this opponent been recognized. and this is remarkable since every soldier knows it is essential to know your enemy.

What kind of future are we wanting to create? It would be possible right now to reduce an incredible amount of carbon and waste production by merely reducing individual consumption. But the economy is consumer driven and reduced consumption would add additional pressure on the already depressed economy.

Expect that whatever environmental solution the government proposes, it will be a consumer compatible movement, modifying consumption to reduce its impact while keeping it profitable. What profit is there in buying and consuming less? We need a global vision of where we are headed, and when that is not provided by the government, we need to ask the long term questions of what new policies will create over time.

From Beyond Zero, by John E. Fernandez

If civilization is to progress a growth culture will have to change into a culture of descent [...]

The idea of sustainable economic growth clashes with the second law of thermodynamics [...] Our approach thus far continues to be incremental improvement because any change more significant than 'incremental' is not currently valued. Yet even accepting these hefty assumptions, there is a growing awareness that all is not well with the concept of beyond zero, not to mention the idea of reaching zero itself.

First there is physics. Anyone familiar with the primary arguments against the idea of sustainable economic growth has already been reminded of the second law of thermodynamics. While it is obvious that society itself constitutes the counter-entropy ordered assembly of energy and materials, our financial value system has failed to account for the real costs of this push against the second law. Ecological Economics has grown in stature and established the framework for an economics that acknowledges and internalizes the second law--thus accounting for effects that used to be known as externalities. However, we are very far away from a governmental and economic framework that even begins to acknowledge, much less work on the principles of the second law.

To put it bluntly, we have discovered that continued growth in consumption cannot be sustained on this planet. It will eventually kill us all. We are now discovering that continued economic growth might not also be possible, since our current economic models require an increased consumption to fuel the economic expansion. The laws of physics trump economic theory. And if we cannot plan on increased economic growth, then what do we plan on?

What future do we envision if we cannot see more riches for ourselves and our children? And how do we meet the current economic crises knowing that the past solutions which ultimately resulted in restoring rising levels of consumption to fuel the economy might now no longer be physically viable?

In the same way that shareholders' demand increasing returns on their investments, do we continue to hold out for a return to economic growth as we have through every downturn since the Great Depression? Or do we recognize the need to contract, both physically and economically, beginning a generation of descent, of modesty and localization -- a conscious retraction from the excesses of the past centuries? There will be real economic consequences to any long term solution. Perhaps this will be part of the price of responsibility.

Any solution that does not address at its core the dependence of the world economy on rising levels of consumption will fail to address the environmental problems that come with it. We cannot simultaneously grow economically and consume less. So the logic would be to make consumption cleaner, thereby keeping the profitability of the system intact. Given the exponential population growth that we expect over the next century, this is only a very short term solution that will result in serious long term problems.
