New Century, Old Disputes

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.

Instead, the Bush administration appeared to suppress scientific reporting on climate change. In 2006, the progressive-leaning Union of Concerned Scientists surveyed sixteen hundred climate scientists, asking them about the state of federal climate research. Of those who responded, nearly three-fourths believed that their research had been subjected to new administrative requirements, third-party editing to change their conclusions, or pressure not to use terms such as “global warming.” Republican politicians, citing the altered reports, argued that there was no unified opinion among members of the scientific community that humans were damaging the climate.

Countering this rejection of science were the activities of many environmentalists, including Al Gore, Clinton’s vice president and Bush’s opponent in the disputed 2000 election. As a new member of Congress in 1976, Gore had developed what proved a steady commitment to environmental issues. In 2004, he established Generation Investment Management, which sought to promote an environmentally responsible system of equity analysis and investment. In 2006, a documentary film, An Inconvenient Truth, represented his attempts to educate people about the realities and dangers of global warming, and won the 2007 Academy Award for Best Documentary. Though some of what Gore said was in error, the film’s main thrust is in keeping with the weight of scientific evidence. In 2007, as a result of these efforts to “disseminate greater knowledge about man-made climate change,” Gore shared the Nobel Peace Prize with the Intergovernmental Panel on Climate Change.
