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

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.

    Out of Sight, Out of Mind

    Abstract: Join Bobby for a showcase of his detailed biological illustration, created under the pen name, NearsightGraphite. Highlighting his process, he’ll discuss the power of the observer and the illustrator’s role as a distiller of torrents of visual data. Bobby’s artwork amplifies intimate, obscure forms of life to give underrepresented organisms louder voices and to visualize their self-worlds. He aims to inspire curiosity in the intricacies of the natural world, and by extension, promote nature conservation.

    Bio: Robert J. Long ("Bobby") is a visual artist and educator from Silver Spring, Maryland. His zoologically-focused artwork has been exhibited throughout the United States and internationally. In 2013 he became Arizona’s first and only finalist in the internationally juried Adobe Design Achievement Awards. His illustrations have been published by Frontiers in Microbiology, Manifest Press, the Confluencenter for Creative Inquiry, and Edible Magazine, among others. Bobby is also an amateur reef aquarist and an avid photographer with experience in macro-photography and an interest in natural subjects.
