Day 3: Finishing Up Climate Change and Cities
I have that folder of articles to pass around. Take note of any that might be useful to your area of interest. They should all be available on-line through the VIU Library.
The major project instructions are now up on the web site under “Courses” at http://web.viu.ca/alexander2.
There are a couple of items in the folder of items of interest (not the same folder with the magazines) that are explicitly about the impacts of climate change on cities – Vancouver and other Canadian municipalities, and how well-prepared they are.
Hopefully, I will also have time at the end of class today to show some short videos about examples of best practices from Europe that stand as potential models for Canada. There are also lots of examples in the two books for which Peter Newman is the lead author – Resilient Cities and Cities as Sustainable Ecosystems.Business Items
The Intergovernmental Panel on Climate Change (IPCC) says that, even with an 80% cut in GHG emissions, we will see a 2°Celsius increase in global temperatures. That will likely result in a loss of 50% of all species, not to mention other dire environmental consequences.
Despite national government inaction, some cities are taking action. The U.S. refused to sign Kyoto. Nonetheless, 165 U.S. cities, led by Seattle, agreed to support it and to implement its provisions to the extent they could.

According to Condon, cities are responsible for 80% of GHGs –”by the way we build and arrange our cities, by all the stuff we put in them, [and] by how we move from one building to the next.”
How many of you grew up in the suburbs? Why did your parents move there? What is your evaluation of the strengths and weaknesses of suburban environments?
House prices are cheaper, but there are added transport costs (partly subsidized) and the already mentioned ecological impacts from infrastructure and additional driving.
In addition, sprawl has facilitated segregation by class, income, race and ethnicity – though more so in the U.S. in Canada. It has also facilitated the ‘hollowing out’ of central cities.Why are cities so central?
East St Louis has lost over 50% of its population and Detroit has lost close to half. Much of the city, which was once a vibrant metropolis, is now a wasteland being re-colonized by artists and other intrepid types (see “Requiem for Detroit?”).
So, if cities are a big part of the problem, they can also be a big part of the solution!Earthworks Urban Farm, Detroit: http://www.cskdetroit.org/EWG/Why are cities so central?
Land use patterns and transportation (automobile dependence) are inextricably linked. From 1997 to 2010, Canada’s vehicle emissions increased by 35%. The least automobile dependence major city in Canada is Montreal, and there only 4% of all houses are single-family dwellings.
In addition to direct production of GHGs by cars, there is the contribution made by related manufacturing and infrastructure, which Condon estimates as 40% of the total of all GHGs.Why are cities so central?
