range of North American forests?
20 miles
60 miles
140 miles
200 miles

Question 6: Which effect of global warming is most likely to interfere with the production of
electricity?
Costal erosion
Changes in the flow of rivers
Shifting wildlife habitats
Question 7: Which continent is likely to be the most vulnerable to climate change?
North America
South Amercia
Africa
Europe
Question 8: In what way could global warming exacerbate human respiratory problems like
asthma?
Higher concentrations of carbon dioxide make it harder for people to breathe
Global warming will reduce the amount of oxygen in the air
Higher air temperatures will increase the production of ground level ozone, which damages
lung tissue
Question 9: Why should coastal property owners be wary of putting up sea walls to protect
their property from the rising sea?
Sea walls are not effective in protecting coastal property
Sea walls cost more than just adding sand to beaches and dunes
Sea walls destroy wetlands and beaches by preventing them from migrating inland as the sea
rises
All of the above
Question 10: Which of the following, if not considered, would cause overestimation of initial
estimates of negative impacts of climate change on agriculture?
Economic adjustments and the broader economic and environmental implications of such
changes
Greater sectorial flexibility and adaptation potential indicated in research results
CO2 fertilization effects
All of the above
