Under the "business as usual" model of climate change, will temperatures change uniformly across the globe?
Examine Figure 48.7 in your text and compare the projected change in
temperature in central South America and central Africa at the equator (draw an imaginary
line across the globe at its widest point and examine a spot in the middle of each continent
along that line). Which of the following best describes the predicted changes?
A. Central South America will warm by an
average of 7–8 degrees; central Africa will
warm by around 3–4 degrees.
B. Central South America will warm by an
average of more than 8 degrees; central
Africa will warm by 1–2 degrees.
C. Central South America will remain about
the same; central Africa will warm by 7–8
degrees.
D. Central South America will warm by 2–3
degrees; central Africa will not change.
E. Both central South America and central
Africa will warm by 4–5 degrees.
