52. Paragraph B

Although most scientists agree that increasing levels of carbon dioxide and other greenhouse gases will

inevitably lead to global warming, no one is certain how fast and how much temperatures will rise and what

the effects will be in any geographical areas. This gives policymakers an excuse for delaying action. Some

experts predict that within two centuries glaciers in the North and South Poles will melt, ocean levels will

rise, and much of what is now the coast of the United States will be under water. They also predict great

droughts and hurricanes, as a result of climate changes.
