I’m housesitting in Alaska, and my return to a place where Mother Nature is in charge once again motivates me to express myself. The front yard of this house is a beautiful rock garden which is low maintenance, and fertilizer and pesticide-free. But the real front yard for this house is the back yard, which backs to 780 square miles of Chugach State Park and its pristine wilderness. That view is grounding, reminding me of what the world looked like before the fossil-fueled growth of the past two centuries. Can we return to that view after the fossil fuels are gone, with clear
air, drinkable water, and an intact food chain? Do we just throw up our hands and accept die-off? Or do we actively work towards a more balanced society? Who’s going to do that and how do we start? This post is about prosaic lawn reform as a symbol of change and personal responsibility for the environment, but first I’m going to wander in synthesis through the threads of current events, to pull that theme together.
I have become sensitive to the silences that come during discussions about the world with others who view the world through a microscope. Silence or a change of topic suggests either denial of my point of view or failure to grasp my frame of reference. While I am peering through an energy lens or macroscope, others may view the world through a lens where money or some other construct makes the world go round instead. One question that stops conversations cold is, “What if our greatest societal challenge is not climate but growth?” That challenge sometimes elicits a glare signifying indignation or perhaps a sense of betrayal that I’m stepping away from my supposed congregation.
Two mechanisms may be occurring when speakers frame climate change as the most important problem that the world has to face. If one’s view of the world is that energy is unlimited, and that we can grow infinitely, and that the environment has a limitless ability to absorb our pollution, then growth is not an important issue. While most people probably know in their hearts that infinite growth is not sustainable, they do not know that energy has limits. So speakers may use a euphemism to subconsciously displace the problem of growth with climate change, since we have been taught the goal of economic growth as a fundamental precept of our society. Secondly, speakers who focus on climate may fail to grasp the severity of the problem of peak oil, because of declining net energy or emergy yields. Thus we lump other assaults on ecosystems such as growth of population, growth of the economy, extraction of resources and other forms of pollution within the problem of climate change. These problems are inextricably connected, but we prioritize them differently depending on our ability to think like a system. Continue reading Is climate change a euphemism for growth?
H.T. Odum spent formative years interrupting his undergraduate study during World War II as a tropical meteorologist in the Panama Canal zone, which helped him to develop understanding of the energetic basis of global systems. He was generally less disturbed about the threat of climate change than he was about our coming bottleneck due to peak oil, proposing that the greatest and most impacting effect of climate change would would be greater extremes and wider swings in weather. On the subject of climate, he was
unsure about whether heating due to greenhouse gases would cause significant rises in sea level or not; one early hypothesis of his in the 1980s was that if heating caused more water vapor to go into the air, then more snow and ice could form in polar regions at high altitudes. Glaciers might melt at their toes at sea level, but might actually accumulate in ice fields, perhaps counteracting the relative rise in sea levels. While there is accumulating evidence that sea levels are rising, and the jury is still out on glaciers at high altitudes/latitudes, there are certainly greater extremes in weather. I ponder these questions as I write about the intersection of climate and peak oil this morning, looking out my window in Anchorage, a weather sample of n=1. We are victims of the polar jet and La Niña here in Alaska this winter, and I’m wondering when it’s all going to melt?!? Continue reading Thinking Like a System about Climate Science
