Public Lectures

Each year, AGCI hosts several public talks featuring leading global change researchers and practitioners. Presented by participants in AGCI’s signature workshop series, these lectures cover the gamut of global change topics from biodiversity threats to urban heat resilience to the history and future of Earth’s climate trajectory. AGCI’s public lecture series honors Walter Orr Roberts (1915-1990), noted humanitarian, scientist, and founder of the National Center for Atmospheric Research (NCAR).

Climate Research and Science Policy: What is Ethical Practice and How Do We Get There?

Prof Mark Howden is the Director of the Climate Change Institute at ANU and a Honorary Professor at Melbourne University. Mark's work has focused on how climate impacts on, and innovative adaptation options for, systems we value: agriculture and food security, the natural resource base, ecosystems and biodiversity, energy, water and urban systems. He helped develop the national and international greenhouse gas inventories which are the basis for the Paris Agreement and has assessed sustainable ways to reduce emissions. Mark has worked on climate variability, climate change, innovation and adoption issues for over 27 years in partnership with many industry, community and policy groups via both research and science-policy roles. Mark has over 400 publications. He has been a major contributor to the Intergovernmental Panel on Climate Change (IPCC) since 1991, sharing the 2007 Nobel Peace Prize. He is now a Vice Chair of IPCC Working Group 2. Mark sat on the US Federal Advisory Committee for the 3rd National Climate Assessment and currently contributes to several national and international science and policy advisory bodies.

Climate Change and the Evolution of Mankind

Dr. Richard Johnson of the University of Colorado will share results from his collaborative research that investigated how climate change during the Miocene caused a near-extinction of our ancestors, and how certain mutations led to the emergence of a lineage that later became humans and modern apes. Insights from these studies have led to a better understanding of how all animals survive climate change, and also for the diseases that are expected to emerge or worsen in the next century. It also may lead to new approaches to stay healthy with increasing global temperatures.

Coral Reefs and Ocean Acidification: Effects of an Unsustainable Energy System

Most of the CO2 released when we burn coal, oil or gas is eventually absorbed by the oceans, where it reacts with seawater leading to acidification. Ocean acidification has been shown to harm many marine organisms, including corals, under controlled laboratory conditions.

This talk will describe how Dr. Calderia's team altered seawater chemistry in a natural ecosystem without any artificial confinement, for the first time ever, and measured the biological response in order to better understand ocean acidification and its impacts on corals.

Dr. Caldiera will describe the effects of ocean acidification on corals, his team's research in the great barrier reef, and the need for energy technologies that provide for human systems while protecting the natural environment.

Climate Change Challenges to Agriculture, Food Security, and Health

Cynthia Rosenzweig presents a Walter Orr Roberts Memorial Public Lecture titled, "Climate Change Challenges to Agriculture, Food Security, and Health." In this talk she will talk about how agriculture is being called upon to ensure both human and planetary health as changes in earth's climate affect food security and ecosystem services at both global and regional scales.

Climate Change: Connecting the Global Challenge to our Local Response

This talk is about how developing high-resolution projections can help real people, from wine growers in California to water managers in Texas, prepare for a changing climate.

Who is Responsible for Climate Change?

This talk focuses on the distinctive responsibilities of the major investor-owned producers of fossil fuels, describing new science on the scale of their contribution to the problem; the actions companies took and could have taken in response to the scientific evidence of climate change; and the evidence that civil society actions to hold companies accountable may be need to hasten our transition to a safe climate future.
