The attention of the world is focused on one thing these days: climate change. From local governments to international governing bodies, all policies and projects are measured through the lens of climate change and reduction in greenhouse gases (GHG).
Here in Our Fair County, county government has a Climate Action Strategy and a Climate Action and Adaptation Plan. The incorporated cities have their own Climate Action Plans. All government policies and projects are assessed as to their relative GHG emissions and carbon sequestration potentials. Every aspect of our lives is viewed as a function of GHG emissions and adaptation to the projected consequences of Global Warming as a result of Climate Change.
Burning of fossil fuels, mainly coal and petroleum, is seen as the ultimate source of GHG and climate change, fostering the belief that reducing human caused GHG emissions will lessen or even stop Climate Change.
The solution proposed is to replace fossil fuels with so-called renewable resources, such as solar, wind, hydro, geothermal, wave and tidal energy sources, those that do not, it is said, produce CO2 at the point of use. This solution has never been tested, since we have only the one Earth on which to conduct this experiment, so we don’t know if reducing GHG will have the desired result.
Quantification of impacts is our normal cultural response to complex problems and their solutions. It’s the science based approach that has led to the technocratic civilization that we now enjoy, tolerate, or decry. Unfortunately, quantification only works if all variables are accounted for. In the case of climate change causes and effects, this turns out not to be the case.
For example, the City of Santa Cruz and the County of Santa Cruz, in company with the County Regional Transportation Commission have issued a Draft Environmental Impact Report (DEIR) on the Coastal Rail Trail Project to build a 1.6 mile bicycle/pedestrian trail alongside the unused railroad tracks traversing the county, which will involve the cutting and removing of ~400 trees along the rail right-of-way, along with the understory, and the paving of the soil beside the tracks. The DEIR claims that the loss of carbon sequestration and lessened removal of CO2 from the atmosphere resulting from the loss of vegetation will be mitigated by planting new trees somewhere else unspecified, plus the reduction in Vehicle Miles Traveled (VMT) on local roads and highways, as commuters leaves their cars at home and walk, bicycle or take a commuter train to and from work.
When the readily quantifiable climate change impacts are preferentially compared for a potential project, there is a danger that the project will be approved regardless of other significant and unavoidable environmental affects. In the case of the coastal rail trail, the environmental effects of the removal of trees and understory on natural habitats, wildlife corridors, shading, soil biological integrity and aesthetic qualities are are analyzed as significant, unavoidable and unmitigatable, yet the project will ultimately be approved and constructed.
It comes back to the old saw: “If the only tool you have is a hammer, everything looks like nail.” Climate change activism has overshadowed environmentalism, especially among Big Green organizations, focusing on replacing fossil fuels with “renewable energy” resources. Even energy luminaries such as Richard Heinberg in his recent article: Can Civilization Survive? considers only the energy costs of transition to renewables, and ignores the environmental impacts of developing solar and wind infrastructure.
Part of the problem is the terminology: “renewable,” and “sustainable.”
Renewable means: “able to be renewed when depleted.” “Renewable” in terms of energy resources, has come to mean: “capable of being replaced by natural ecological cycles or sound management practices.” In Climate Change terms, “renewable” implies that finite resources such as petroleum and coal are capable of being replaced by solar, wind, gravity, tides and hydro dams as “renewable resources.”
There are two problems with this approach. Replacing fossil fuels with “renewables” means replacing a highly dense, reliably available, relatively inexpensive energy source with a dispersed, unreliable energy resource that requires reliable nonrenewable backups and extensive battery storage capability. Different is not the same.
In addition, “renewable” resources require complex and costly infrastructure to transform the dispersed unreliable energy sources into reliable energy useful to our complex and ever growing civilization. This infrastructure is built with finite resources such as metals, rare earth minerals, lubricating oils, polycarbonate plastics, silicon cells, exotic chemicals and cement, all of which require mining, processing, manufacture, transportation, distribution, dismantlement and recycling.
By this analysis, “renewables” are not renewable at all, nor are they sustainable, any more than are non-renewable resources. In addition solar, wind, hydro, geothermal, off-shore wind, wave and tide energy require the destruction of natural habitats and extensive impacts on the species that live there. We are seeing vast acreages of fragile desert ecosystems slathered with solar panels, access roads and support facilities, hills and plains dotted with wind generators and piles of dead raptors and other birds and bats.
This hardly qualifies as “natural ecological cycles or sound management practices.”
“Sustainable” means “able to be continued indefinitely.” In Climate Change parlance, sustainable means: “the integration of environmental health, social equity and economic vitality in order to create thriving, healthy, diverse and resilient communities for this generation and generations to come.”
Notice the glaring absence of other than human species?
As Richard Heinberg points out, global energy systems cannot replace fossil fuels with so-called “renewable energy” sources within the existing political/economic/social system of perpetual economic and population growth at current levels of per capita consumption.
What does this mean for us locally?
Life here in Our Fair County, all life, not just human life, is unsustainable in our current political, economic and social systems. Unsustainable means it can’t go on forever.
“If something cannot go on forever, it will stop,” said Herbert Stein (1916 – 1999), chairman of the Council of Economic Advisers under Richard Nixon and Gerald Ford.
If we wish to continue a meaningful existence for all life here in Our Fair County, we must achieve four goals:
- Limit population and economic growth
- Limit per capita consumption
- Limit travel hither and yon
- Limit natural habitat destruction
We must extend equity and inclusiveness to all life in our plans and policies for human life, in a truly renewable and sustainable society.
