Climate Modeling Panel Discussions

America Resilient: Projecting and Preparing for the Effects of Climate Change — A virtual climate conference convened by Argonne National Laboratory.

Equipping Local and Regional Communities to Act: The Path to High-Resolution Climate Models Informing Adaptation Strategies
To build resilient communities, leaders and community members need information about the potential impacts of climate change decades in the future. This discussion will focus on high-resolution climate projections and how they guide the development of local actions and strategies optimized to minimize climate impacts. Speakers will also discuss the need for two-way communication between researchers and community members to enable science-driven solutions for communities' biggest challenges, and the path toward cutting-edge science providing the best possible guidance to stakeholders as they invest in climate resilience.

Wuebbles also led the development of the School of Earth, Society, and Environment, and was its first director.

Wuebbles is an expert in atmospheric physics and chemistry, with over 500 scientific publications related to the Earth’s climate, air quality, and the stratospheric ozone layer. However, his work goes well beyond that through providing analyses and development of metrics used in national and international policy and in developing analyses for understanding climate impacts on society and ecosystems, plus potential resilience and societal responses. He has been a leader in a number of international and national scientific assessments, including being a Coordinating Lead Author on several international climate assessments led by the Intergovernmental Panel on Climate Change (IPCC) that resulted in IPCC being awarded the Nobel Peace Prize in 2007.

He co-led the first volume of the 4th U.S. National Climate Assessment published in November 2017 that assesses the science of climate change and its effects on the United States. He led a new assessment on the impacts of climate change on the Great Lakes that was published in March 2019 and he is currently leading a special assessment of the impacts of climate change on the state of Illinois that will be published in 2021. Wuebbles has received major awards, including the Cleveland Abbe Award from the American Meteorological Society, the Stratospheric Ozone Protection Award from the U.S. Environmental Protection Agency, and the Bert Bolin Global Environmental Change Award from the American Geophysical Union He is a Fellow of three major professional science societies, the American Association for the Advancement of Science, the American Geophysical Union, and the American Meteorological Society.

Science in Action
U.S. Department of Energy National Labs Advancing Actionable Climate Projections
New advances in computing, including artificial intelligence, are revolutionizing the accuracy of climate models. In this conversation, researchers from U.S. Department of Energy national laboratories will outline the path and vision for developing models that meet two key needs: projecting climate impacts decades in the future and delivering highly accurate data for individual regions and cities. They will discuss how these high-resolution climate projections will provide actionable information that individual communities can use to build resilience.
