The Global Warming Debate

James G. Titus states that over the past decade, most climatologists have agreed that a doubling of CO2 would eventually raise global temperatures 1.5 to 4.5o Centigrade, which Titus says is expected to occur by the middle of next century. He also cites some studies that believe the warming could be even greater than this and finds that methane, chlorofluorocarbons, nitrous oxide, carbon tetrachloride, and other gases released into the atmosphere by various human activities also have a greenhouse effect and so might increase the overall effect (Titus 311-312).

ter subsidies in the West (Titus 311). Titus frames the problem well by indicating how policymakers must set priorities and by detailing the criteria they should use in evaluating potential responses. The major problem he foresees is the difficulty of weighing present versus future benefits (Titus 314). He divides the possible responses into categories: no action today; anticipatory action; planning; and research and education (Titus 315). Titus feels that once a problem is defined, Americans are likely to respond with the needed money to correct it. He also feels that many of the responses constitute easy solutions that would address the problem without arousing opposition or later being seen as ill-advised. Even more costly options, says Titus, would prove to be good investments (Titus 322). Bush agrees that the climate of the Earth changes all the time, sometimes in a subtle manner and sometimes in a dramatic way, and recent evidence analyzing the various ice ages that have come over the Earth suggests that there is a flip-flop in the climate that moves the Earth out of a warm interglacial period and into a cold glacial period in a process taking only three to five years (Bush 323). This makes it a real possibility tha
