Climate Predictions and Projections in the Coming Decades: Uncertainty due to Natural Variability
James Hurrell, Scott Presidential Chair of Environmental Science and Engineering, Colorado State University

Future climate change at local and regional scales will result from a combination of human and natural factors. In this talk, I show that unpredictable, internally generated climate fluctuations make a substantial contribution to climate trends projected for the next 50 years over North America and Europe. Results are based on large ensembles of climate change integrations with the Community Earth System Model (CESM). I also will show that the large-scale atmospheric circulation is responsible for much of the diversity in climate change projections across the individual ensemble members. I will conclude by discussing some implications of the results for model validation, intermodel comparisons, and interpretation of observed climate trends.

A Role for Organometallic Chemistry in Sustainable Energy Accessibility: Synthetic Analogues of Hydrogenases
Marcetta York Darensbourg, Distinguished Professor of Chemistry, Texas A&M University

From lessons learned in Ted Brown’s lab of the most fundamental chemistry of metal-carbon bonds in organolithium compounds, to the synthetic development of biomimetics containing carbon monoxide as ligands to iron in biology, the last half-century has provided this organometallic chemist with the background to contribute to the understanding of hydrogenases (H2ases). As nature’s masterpiece enzymes for hydrogen production and its use as an energy vector in hundreds of microorganisms, an array of enzymatic and spectroscopic probes, crowned by modern protein x-ray diffraction technology, provide opportunities for structure-function analysis of the intricate H2ase active-site molecular machinery, perhaps more explicitly than in any other known catalyst. This lecture will focus on key questions in a structure-function analysis of bioinspired electrocatalysts for the Hydrogen Evolution Reaction.

Speaker Biography
Professor Marcetta Y. Darensbourg is a native of Kentucky, with a Ph.D. from the University of Illinois. Following academic posts at Vassar College and Tulane University, she joined the faculty at Texas A&M University in 1982. She holds the title of Distinguished Professor of Chemistry. Trained as an organometallic chemist at the University of Illinois in the laboratories of Professor Theodore L. Brown, and with earlier research programs in low-valent transition metal hydrides, the possibility of metal hydrides in nature, specifically as intermediates in hydrogenase enzymes lured her into the new field of bioorganometallic chemistry. She has been a leader in the development of synthetic analogues of the diiron hydrogenase active site and the insight they bring to the catalytic mechanism of these natural fuel cell catalysts. Metalloenzyme active sites that catalyze carbon-carbon coupling reactions but use abundant metals such as nickel also inspire her research activities.

She was an inaugural Fellow of the American Chemical Society in 2009 and was elected as a fellow of the American Academy of Arts and Sciences in 2011, to the Royal Society of Chemistry in 2014, and the National Academy of Sciences in 2017. Most recently, she was selected by the Southeastern Conference as the 2018 SEC Professor of the Year.

Harnessing Plants to Fight Climate Change

Joanne Chory, Investigator, Howard Hughes Medical Institute; Professor and Director, Plant Biology Laboratory at The Salk Institute for Biological Studies

Steadily rising atmospheric carbon levels pose a significant challenge due to their effects on climate. To counteract this CO2 accumulation, technologies are needed that draw down CO2 and store it stably for centuries. Plants are a natural solution to this challenge, as their main activity is fixing CO2 and converting it into biomass. However, most of the biomaterials synthesized by plants are degraded annually, releasing the fixed carbon back into the atmosphere and limiting plants’ ability to reduce atmospheric CO2 levels. We propose to develop plant varieties that can stably sequester significant amounts of carbon in the soils of marginal lands through the production of suberin, a highly stable biopolymer.

Managing World Soils for Confronting the Challenges of Climate Change
Rattan Lal, Distinguished University Professor of Soil Science and Director of the Carbon Management and Sequestration Center, Ohio State University, and Adjunct Professor of the University of Iceland.

World soils can be a source or sink of atmospheric carbon (C) depending on land use and management. The magnitude of the depletion of soil organic C (SOC) depends on climate, soil profile characteristics, landscape position, soil moisture and temperature regimes, soil texture, clay mineralogy and internal drainage. In general, the extent and severity of soil degradation (i.e., decline in soil aggregation and aggregate stability; accelerated erosion by water and wind; salinization, nutrient depletion, elemental imbalance) exacerbate the magnitude of SOC depletion. Therefore, conversion of degraded soils to a restorative land use and adoption of conservation-effective practices can create a positive soil/ecosystem C budget and make soil a sink of atmospheric CO2.

Carbon Capture and Utilization (CCU): Polycarbonates Produced from Carbon Dioxide

Donald J. Darensbourg, Distinguished Professor of Chemistry, Texas A&M University

Carbon capture and utilization (CCU) processes represent effective options for reducing CO2 emission. In this context, several processes exist that use sizeable quantities of carbon dioxide, e.g., the production of urea, methanol, cyclic carbonate, and polymers. CCU’s contribution to reducing the greenhouse effect would be greatly enhanced if the technology was available for efficiently converting CO2 into energy-rich products or fuels. The copolymerization of CO2 and epoxides to synthesize degradable aliphatic polycarbonates is a promising approach. For example, aliphatic polycarbonates have been proposed as alternatives to petro-based chemicals in automotive, medical, and electronic applications. This presentation will focus on the development of efficient procedures for the preparation of CO2-based polymeric materials for wide scale industrial use, as well as designer polymers for potential applications in the biomedical fields.

Speaker biography:
Donald J. Darensbourg was born in Baton Rouge, LA., in 1941 and received his B.S. and Ph.D. degrees from California State University at Los Angeles and the University of Illinois/Urbana, respectively. Following a nine-month period at the Texaco Research Center in Beacon, NY, he was on the faculties of State University of New York at Buffalo from 1969 to 1972 and Tulane University from 1973 to 1982. He has been at Texas A&M University since 1982 where he currently is a distinguished professor. His research interests have been in mechanistic inorganic/organometallic chemistry with an emphasis on catalytic processes. Presently, his focus is on the utilization of CO2 as both a monomer and solvent in copolymerization reactions with oxiranes and oxetanes, and the ring-opening polymerization of renewable monomers such as lactides.

Can Nanotechnology Save the World?
Catherine J. Murphy, Larry R. Faulkner Endowed Chair in Chemistry, University of Illinois at Urbana-Champaign

Nanotechnology is the applied study of objects in the 1-100 nm regime, especially if the objects have size-dependent behavior in that regime. In this talk I will outline the fundamental science behind nanotechnology and describe how many scientists and engineers are using nano-enabled technologies for cleaner water, cleaner air, cleaner energy, and improved agricultural practices. But in addition to the promises of nanotechnology, there is peril in their potential environmental impacts. I will also describe work from the Center for Sustainable Nanotechnology, a consortium of universities across the country, that address the latter challenge.
