From diagnosis to attribution: constraining carbon cycle dynamics using contemporary observations

Abstract
Future climate predictions and societal responses to climate change require an in-depth understanding of carbon-climate feedbacks and changes to the carbon cycle. In turn, this understanding hinges on our ability to diagnose the sources and sinks of carbon dioxide (CO2) and methane (CH4), their variability and future evolution. My research focuses on developing and implementing statistical and numerical methods that utilize advances in observational and modeling strategies to study the carbon cycle from global to regional domains and across a variety of space-time scales. In this talk, I will show two unique examples to illustrate how information from space-based sensors can be used to understand the response of the carbon cycle to natural and anthropogenic perturbations: first, we will look at how the global carbon cycle responded to the 2015-2016 El Niño event, and second, how short-term, regional changes in fossil fuel emissions during the COVID-19 pandemic have impacted the carbon cycle? I will highlight how insights gained from these applications are informing model and technological developments to make better use of information from current and future space-based missions. Finally, I will also discuss the potential (and the necessity) for a coordinated diverse observing portfolio, comprising of airborne, remote sensing and ground measurements, to obtain a deeper understanding of the changing carbon cycle and its co-evolution with atmospheric composition and climate.

    Being a More Strategic, Evidence-Based Science Communicator  

    Science communicators who want to have sustained impact need to think carefully about what they want to achieve from the time and money they devote to communication. Clearly describing scientific findings and telling engaging stories is rarely the end goal. Instead, science communicators almost always want to affect behavior, including the likelihood that people will trust science when faced with new challenges. Smart science communicators also create communication opportunities to improve their own thinking and behavior. In this talk, John will share and discuss his recent research on what a more strategic version of science communication might look like and what steps social science research suggests might help us get there.

    Dr. Besley is the Ellis N. Brandt Chair of Public Relations at Michigan State. He studies public opinion about science and scientists’ opinions about the public. In recent years, he’s become especially interested in how to help science communicators think about their communication choices in more strategic and evidence-based ways.
