The Carbon Brief Interview: Dr Katharine Hayhoe

Dr Katharine Hayhoe is a professor in the department of political science at Texas Tech University and director of its Climate Science Center. She was a lead author on the Climate Science Special Report, part of the fourth US National Climate Assessment, which was published in early November 2017. Hayhoe is also a science advisor on the US documentary series Years of Living Dangerouslyand was named as one of Time magazine’s 100 Most Influential People in 2014.

Together with her husband, Hayhoe wrote A Climate for Change: Global Warming Facts for Faith-Based Decisions. She also writes and produces an animated series on YouTube called “Global Weirding”.

  • Hayhoe on her early research career: “I was looking around for an extra course that might be interesting and I saw a class on climate modelling over in the geography department.”
  • On regional climate information: “I evaluate the downscaling methods we use to take the relatively coarse information from the big global models and downscale it to much higher spatial and sometimes even high temporal resolution at the local to regional scale.”
  • On improving climate models: “The smaller the spatial grids and the smaller the time step we use in the model, the better we’re able to actually explicitly resolve the physical processes in the climate.”
  • On the biggest unknowns of future climate change:“There are long-term processes in the climate system that we’re not yet incorporating in our models and when we do, the final outcome of this inadvertent experiment that we’ve been conducting with our planet is likely to be worse, not better, than we thought.”
  • On Donald Trump’s presidency: “I know this sounds very strange – but I really believe that his election galvanised people into personal action in a way that never would have happened if Clinton had been elected.”

I Was an Exxon-Funded Climate Scientist

ExxonMobil’s deliberate attempts to sow doubt on the reality and urgency of climate change and their donations to front groups to disseminate false information about climate change have been public knowledge for a long time, now.

Investigative reports in 2015 revealed that Exxon had its own scientists doing its own climate modeling as far back as the 1970s: science and modeling that was not only accurate, but that was being used to plan for the company’s future.

Now, a peer-reviewed study published August 23 has confirmed that what Exxon was saying internally about climate change was quantitatively very different from their public statements.

Specifically, researchers Geoffrey Supran and Naomi Oreskes found that at least 80 percent of the internal documents and peer-reviewed publications they studied from between 1977 and 2014 were consistent with the state of the science – acknowledging that climate change is real and caused by humans, and identifying “reasonable uncertainties” that any climate scientist would agree with at the time.

Yet over 80 percent of Exxon’s editorial-style paid advertisements over the same period specifically focused on uncertainty and doubt, the study found.

The stark contrast between internally discussing cutting-edge climate research while externally conducting a climate disinformation campaign is enough to blow many minds. What was going on at Exxon?

I have a unique perspective – because I was there.

From 1995 to 1997, Exxon provided partial financial support for my master’s thesis, which focused on methane chemistry and emissions. I spent several weeks in 1996 as an intern at their Annandale research lab in New Jersey and years working on the collaborative research that resulted in three of the published studies referenced in Supran and Oreskes’ new analysis.
