The report by the
Intergovernmental Panel on Climate Change (IPCC) last Thursday was the
most significant announcement that has been made in human history… That
proclamation may seem loaded, but with growing scientific consensus about
the effects climate change will have, it is not understatement. The IPCC
reported with 90% certainty that humans are the most likely cause of
climate change. As of that moment, politics in North America changed
significantly… or did it?
The initial reaction of the Bush administration was promising. Energy
Secretary Sam Bodman accepted that the IPCC report left no doubt human
actions were causing climate change. Unfortunately Bodman also stated that
capping greenhouse gas emissions was unrealistic for the US because it
would hurt industry. Bodman further suggested that the US was a small
player in global greenhouse gas emissions.
Both statements were bold lies, but the latter more shocking since it has
been established that with 25% of global emissions, the US is the world’s
largest contributor of greenhouse gases. In addition, it was recently
reported that The American Enterprise Institute, (an Exxon-Mobile funded
think tank with close ties to the Bush Administration), has offered $10
000 to scientists who will dispute the science IPCC report. Not surprising
from the group that gave us WMD.
The Harper reaction paralleled the Bush reaction. Environmentalists in
Canada breathed a sigh of relief when Harper acknowledged that what the
IPCC had stated was true and could not be ignored. The sigh was quickly
followed by a gasp when Harper stated that it was ‘ridiculous’ to expect
that anything could be done immediately to reduce greenhouse gas
emissions; cars need to run, industry could not be ‘shut down.’ Apparently
Harper did not read the widely reported poll by The Strategic Counsel.
In the poll, 93% of Canadian respondents indicated that they would be
willing to make sacrifices in order to combat climate change. Among other
indicators, 62% indicated that they would be willing to have the economy
grow at a significantly slower rate and 61% would reduce by half the
amount they drive. Clearly ‘Steve’ is as out of touch as the Bush
Administration.
The IPCC made it clear that there is no room for governments to ignore the
scientific consensus of climate change. Our current government has
acknowledged that fact, but chooses to carry out its dinosaur agenda of
economy first. For our own well being, we can not allow that agenda to
continue.

Mr. Rahn brought up an important point in his critique of my January 17
article: a diverse energy base is a major component of addressing the
energy crisis. I support that perspective as well as the idea of biofuels
helping to displace fossil fuel consumption; if done so in a sustainable
way. However, there is debate regarding the sustainability and
environmental impact of producing biofuels using current agricultural
techniques in North America. In order to address Mr. Rahn argument, I
conducted a literature review of scientific publications regarding
biofuels.
Science magazine published an article entitled, “Ethanol can contribute to
energy and environmental goals,” a review of publications related to
ethanol production and energy balance. The article demonstrated flaws in
the publication from which I had received my original information
regarding the energy balance of ethanol (my apologies). The authors
estimated that ethanol produces around 25% more energy than it consumes in
production. Also suggested was that biodiesel could produce much more
energy than consumed by using future technologies.
However, the authors demonstrate that greenhouse gas reduction through
burning ethanol is only 13% when compared with equivalent fossil fuel
burning. The authors note that the marginal reduction is due mainly to
fossil fuel inputs to grow corn for ethanol. Corn grown in our current
agricultural system is not carbon neutral; it requires fossil fuels for
tractors, pesticides, transportation and refinement.
An article from PNAS, “Environmental, economic, and energetic costs and
benefits of biodiesel and ethanol biofuels,” noted that biofuel production
to replace petroleum will affect the amount of land dedicated to food
production. If all current corn and soybean production in the US were
dedicated to biofuel production, only 12% of petroleum needs would be met.
This is a significant finding, especially in light of the fact that we
expect to add an additional 3 billion mouths to the planet in the next 50
years.
There are other problems regarding soil erosion, forest loss and the
degradation of marginal lands if biofuels were pursued as a replacement to
fossil fuels. With the impending climatic change because of fossil fuel
burning, it is questionable whether we will be able to dedicate such a
large portion of our crop to energy consumption. Therefore if biofuels are
produced in a non-carbon intensive way… drastic reduction in overall
energy use is still the only answer to solving the global energy crisis.

During a conference call
earlier this month, the premiers of Canada agreed to begin pursuit of a
national east-west energy grid in order to better distribute resources
between the provinces. The Manitoba government has long desired to link
Manitoba’s vast hydro expanse with power hungry Ontario and future dam
development in Manitoba hinges upon establishing a link. Hydro dams are
considered ‘clean, green’ energy sources, though the social and
environmental impacts of the dams are often not considered in this
assessment.
The construction of large hydro-electric dams generates methane and carbon
dioxide from organic matter decomposition with flooding. However, in the
Boreal regions of Canada, greenhouse gas generation due to hydro projects
is not significant when compared with coal generated electricity. The most
prominent environmental issue for dams in Canada is the release of mercury
from flooded soil into water. Mercury pollution in water leads to high
levels of mercury in fish, which has lead to outbreaks of minamata disease
(mercury poisoning) in Aboriginal communities in Northern Ontario.
The effect of dam development on Aboriginal communities has been
devastating in Manitoba. During the 1960’s and 70’s, massive development
flooded traditional territories amongst people who had not had contact
with southern people or governments since the signing of the numbered
treaties, with the exception of residential schools. The diversion of
rivers and the disappearance of lands led to huge declines in the animal
resources that these communities had used for sustenance and trade.
Contrary to public belief, the dams impoverished the communities and left
little in the way of compensation. The introduction of construction camps
brought alcohol to Aboriginal communities, at a time when individuals were
suffering the loss of their traditions. Today, this legacy lives on. The
Canadian north is often referred to as ‘the fourth world’, a group of
third world communities existing in a developed nation. Unemployment, lack
of access to clean water and poor health are the characteristics of the
north.
Dam development today includes more open communication with Aboriginal
communities, but the context of development has changed. Today’s
governments are not misinforming Aboriginal people in order to get
projects pushed through, they are bribing them, dealing with impoverished
people, desperate for income. If Ontario is planning to import this
energy, Ontario residents should share in the knowledge of the legacy of
dam development in the north.
