Climate Change Poses Major Risks for Unprepared Cities
A new examination of urban policies has been carried out recently by Patricia Romero Lankao. She is a so-
ciologist specializing in climate change and_____________(51) development. She warns that many of the world'5
fast-growing urban areas,especially in developing countries,will likely suffer from the_____________(52)of
changing climate. Her work also concludes that most cities are failing to_____________(53)emissions of carbon
dioxide and other greenhouse gases. These gases are known to affect the atmosphere.
"Climate change is a deeply local issue and poses profound_____________ (54) to the growing cities of the
world,"says Romero Lankao. "But too few cities are developing effective strategies to protect their residents."
Cities are_____________(55)sources of greenhouse gases.And urban populations are likely to be among
those most severely affected by future climate change.Lankao's findings highlight ways in which city-resi-
dents are particularly vulnerable,and suggest policy interventions that could offer immediate and longer-term
____________ (56).
The locations and dense construction patterns of cities often place their populations at greater
_____________(57)for natural disasters.Potential threats associated with climate include storm surges and pro-
longed hot weather. Storm surges can flood coastal areas and prolonged hot weather can heat_____________(58)
paved cities more than surrounding areas. The impacts of such natural events can be more_____________(59)in
an urban environment. For example,a prolonged heat wave can increase existing levels of air pollution,causing
widespread health problems.Poorer neighborhoods that may_____________(60)basic facilities such as drinking
water or a dependable network of roads,are especially vulnerable to natural disasters.Many residents in
poorer countries live in substandard housing_____________(61)access to reliable drinking water,roads and
basic services.
Local governments,therefore,should take measures to_____________(62)their residents."Unfortunately,
they tend to move towards rhetoric_____________(63)meaningful responses,"Romero Lankao writes,"They don't
impose construction standards that could reduce heating and air conditioning_____________(64).They don't em-
phasize mass transit and reduce automobile use.In fact,many local governments are taking a hands-off ap-
proach."_____________(65),she urges them to change their idle policies and to take strong steps to prevent
the harmful effects of climate change on cities.
_________(55)
A:major
