The recent confirmation of Gina McCarthy—a tough air regulator with a passion for reining in greenhouse gas emissions—as head of the Environmental Protection Agency and Obama’s “national climate action plan” speech at Georgetown University last month signal two things about climate change politics in the United States. One is a glimmer of hope for modest if inadequate policy change. The other is the beginning of badly needed cultural change.
For years, climate change has been one of the great political unmentionables. In the autumn of 2012, after months of crippling drought, a federal drought researcher told me he would infrequently bring up climate change during public lectures. But farmers in the heartland might sometimes ask him privately whether climate change was real—at the end of a talk, while their peers weren’t listening. Such reticence may be common among state, local and federal agencies that deal with the public. In an in-depth story this month, Mother Jones reports that even after Hurricane Sandy ravaged the East Coast, it has been difficult for emergency managers at any level of government to speak directly about the threats of climate change.
The topic has been so politically taboo, even on the left, that Obama advisers told the president to keep quiet on the (allegedly) politically risky subject for years, according to National Journal. Media coverage on climate change steadily declined between 2009 and 2012. And with a dearth of useful information available to Americans, public opinion has simply fluctuated with the weather: research shows that belief that climate change is happening drops in cold years and rises again with a heat wave. (A sign that the public misunderstands the science: climate change stacks the odds in favor of weather extremes and heat waves, but doesn’t mean the end of cold winters.)
Perhaps it’s fortunate then that Obama rode in to his second term after a heat wave and a megastorm. An uptick in public interest on climate change, following the scorching 2012 summer and Hurricane Sandy, has shifted a few things in the Democrats’ strategy in the past couple of months. According to a bipartisan poll released a few days ago, Obama’s base of millennial voters is especially concerned: 79 percent of under-35 voters are more likely to cast a ballot for candidates who support Obama’s climate policy; 73 percent believed that candidates who denied the science of climate change were out of touch, ignorant, or crazy.
