THREE EXPERTS REFLECT ON:
CLIMATE CHANGE,
CITIES AND
THE NEED TO
SCALE UP GREEN
INFRASTRUCTURE

KEVIN BEHAN, DR. DAVID R. TILLEY & DR. BRAD BASS
1. What are the main issues facing North
American cities with respect to climate change?
Kevin Behan (KB): There are considerable,
but separate issues facing North American
cities around mitigating against, and
adapting to climate change. Considering
mitigation, much of the 'low hanging fruit'
has now been picked. Many of our point
source industrial greenhouse gas emissions
have been regulated with controls in place.
Future mitigation will rely on improvements to building energy and transportation efficiency. Fossil fuel companies
continue to receive considerable subsidies
to bolster their market competitiveness, so
the cost of 'going green' is currently borne
by the individual. All orders of government
need to work together to create a level
playing field where the negative external
costs of fossil fuel energy are accounted
for, increasing the attractiveness of
renewables. Governments, developers and
utilities need to work together to build the
market for home efficiency and net zero
ready homes.
Regarding adapting to climate change,
we are now at (or indeed, past) the point
where the implementation of adaptation
projects must happen. Adaptation projects
tend to have more localized benefits. Reflecting this, municipal governments have
had little or no financial or resource assistance from higher orders of government
to deliver adaptation projects. The absence
of a concerted effort to build resilience in
our cities remains a huge stumbling block
to adaptation.
DT: The number of deadly summer heat
waves that hit major cities is expected
to increase in frequency and intensity as
the climate warms. Excess urban heat is
especially troublesome because the population of cities is growing and the mean age
of city residents is increasing. The elderly
tend to be more prone to suffering death
and disease due to heat waves. Cities with
the highest density populations and least
amount of green space tend to suffer the
most from heat waves. Flooding due to big
storm events is also a major concern. The
spread of hard surfaces for parking lots,
buildings, roads and the loss of green space
in cities exacerbate the damage caused by
heat waves and floods.
