Figure 32.12 Supporters and protesters of same-sex marriage gather in front of San Francisco’s City Hall (a) as the California Supreme Court decides the fate of Proposition 8, a 2008 ballet measure stating that “only marriage between a man and a woman” would be valid in California. Following the Iowa Supreme Court’s decision to legalize same-sex marriage, supporters rally in Iowa City on April 3, 2009 (b). The banner displays the Iowa state motto: “Our liberties we prize and our rights we will maintain.” (credit a: modification of work by Jamison Wieser; credit b: modification of work by Alan Light)
WHY FIGHT CLIMATE CHANGE?
Even as mainstream members of both political parties moved closer together on same-sex marriage, political divisions on scientific debates continued. One increasingly polarizing debate that baffles much of the rest of the world is about global climate change. Despite near unanimity in the scientific community that climate change is real and will have devastating consequences, large segments of the American population, predominantly on the right, continue to insist that it is little more than a complex hoax and a leftist conspiracy. Much of the Republican Party’s base denies that global warming is the result of human activity; some deny that the earth is getting hotter at all. This popular denial has had huge global consequences. In 1998, the United States, which produces roughly 36 percent of the greenhouse gases like carbon dioxide that prevent the earth’s heat from escaping into space, signed the Kyoto Protocol, an agreement among the world’s nations to reduce their emissions of these gases. President Bush objected to the requirement that major industrialized nations limit their emissions to a greater extent than other parts of the world and argued that doing so might hurt the American economy. He announced that the United States would not be bound by the agreement, and it was never ratified by Congress.
