Abstract: Earth is warming, and the damages associated with climate and weather extremes (droughts, heatwaves, floods, hurricanes) are increasing. Projecting these changes into the future is difficult due to: incomplete understanding of the physical processes, inadequate numerical models and resolution, and relatively short observational records. Here we highlight some of the current grand climate change problems, in particular connecting global changes to fine-scale impacts, and we present some recent work analyzing how climate and weather extremes are changing in response to global warming.
Ryan L. Sriver is an associate professor of atmospheric sciences at the University of Illinois at Urbana-Champaign. Prior to joining UIUC in 2012, he worked as a research associate in Penn State's Department of Geosciences and as a NOAA Climate and Global Change postdoctoral fellow in Penn State's Department of Meteorology. Ryan graduated from Purdue University with a PhD in Earth and Atmospheric Sciences. Ryan's research seeks to develop a deeper understanding about the physical processes influencing variability within Earth's climate system and to quantify relevant uncertainties surrounding future climate projections. His work combines observational products, statistical methods and tools, and numerical models spanning a wide range of complexities and scales to understand how extreme weather and climate events are changing with global warming, what are the physical drivers, and what are the implications for natural and human systems. His research interests include: Climate Dynamics, Earth System Modeling, Ocean-Atmosphere Interactions, Uncertainty and Risk, Weather and Climate Extremes, Tropical Cyclones, Sea-Level Rise, Seasonal Prediction, and Multi-Sector Dynamics.
