Texas Monthly has an interesting profile of Katharine Hayhoe.
co-author of the last two National Climate Assessments and a reviewer on the Nobel Prize–winning Intergovernmental Panel on Climate Change, Hayhoe—the daughter of missionaries and the wife of a pastor—is herself an evangelical Christian. In her talks, she uses the Bible to explain to Christians why they should care about climate change and how it affects other people, from a poor family on the island nation of Kiribati who will be displaced by rising sea levels to an elderly couple in Beaumont who can’t afford to pay for air-conditioning in Texas’s increasingly sweltering summers. As she puts it, “The poor, the disenfranchised, those already living on the edge, and those who contributed least to this problem are also those at greatest risk to be harmed by it. That’s not a scientific issue; that’s a moral issue…”
If she was going to leave astronomy behind, Hayhoe wanted to do policy-relevant climate science. When she was considering graduate programs, she was thrilled to learn that Don Wuebbles, who had been instrumental in addressing the chlorofluorocarbon problem in the eighties, was the new head of the department of atmospheric science at the University of Illinois Urbana-Champaign. He would serve as her adviser for both her master’s degree and her doctorate. Under Wuebbles’s guidance, Hayhoe eventually began focusing on statistical downscaling, which was still a relatively new field when she started graduate school, in 1995. “There was very little of this being done at the time,” Wuebbles recalled recently, “and the methods were not capturing the full extent of the science, so she set about to develop a new technique and very successfully did so. She’s brilliant…”
Hayhoe’s first step is always to “genuinely bond over a shared value,” with an emphasis on that shared value’s being genuine. “The key is not to pretend; we can all smell someone who is not genuine a mile away,” she said. “If I’m talking to farmers or ranchers or water managers, I start off by talking about what we all care about, which is making sure we have water. And that, for many Texans, is almost as strong of a value as whatever it says in the Bible.” Her next step is to connect that issue to climate change. So when talking about water, she describes how climate change is changing rainfall patterns. “We’re getting these heavy downpours, and then we’re getting longer dry periods in between, and our droughts are getting stronger because the warmer it is, the more water evaporates out of our lakes and rivers and our soil,” she said. She tries to end her talks with solutions that inspire people, ranging from the personal (measuring your carbon footprint and installing energy-efficient light bulbs) to the large-scale (putting a tax on carbon). Hayhoe herself is most excited by the efforts of Elon Musk, the CEO of Tesla Motors and founder of SpaceX. “If I had to pick one person to save the world—and I don’t think any one person will but if I had to pick one—it would be him.” She is excited about the battery packs that Tesla is developing, declaring energy storage the “single technology that will make the most difference.”
