Climate Change: Earth, Sea, and Sky

6 PM - 8 PM (AZ Time)
March 18, 25, April 1, 8, 15, and 22, 2021





This course was originally scheduled for Spring 2020 but was postponed due to COVID-19

Have you ever watched in wonder at our gorgeous earth, sea, and sky interacting to provide us with the air we breathe, water we drink, and food we eat? Come hear UA professors of geosciences, hydrology, and atmospheric sciences discuss how our climate and weather systems evolved and are changing--and how that will affect our relationship with the earth, sea, and sky and with each other. This course will cover the evolution of earth systems that produced the climate of today (Earth with Professor Tierney), the role of the ocean in modulating the climate of today and shaping the climate of the future (Sea with Professor Russell), and what these changes will mean for us, our desert climate, and our weather (Sky with Professor Castro).

Registration will open online on Monday, November 23, 2020 at 8 AM (AZ Time)

  • Classes will be delivered online via the Zoom video conferencing platform. Course will be password protected and only available to enrolled students.
  • All class sessions will be recorded and made available to enrolled students for a limited time to assist those who may not be able to attend the live class times.
  • Enrolled students may withdraw from a course and receive a tuition refund if the request is received before the second class session.

Meet Your Professor

Associate Professor
Department of Geosciences

Jessica E. Tierney is a paleoclimatologist and and UA Associate Professor of Geosciences. She specializes in reconstructing past climate change using molecular fossils and statistical techniques. Dr. Tierney is an American Geophysical Union Fellow and medalist, a Packard Foundation Fellow, and a lead author on the upcoming IPCC sixth assessment report.

Department of Geosciences

Joellen L. Russell is an oceanographer and climate scientist, a UA Professor in the Department of Geosciences, and the Thomas R. Brown Distinguished Chair of Integrative Science. Dr. Russell’s research uses global climate and earth system models to simulate the climate and carbon cycle of the past, the present and the future, and develops observationally-based metrics to evaluate these simulations. Prof. Russell is the lead for the modeling theme of the Southern Ocean Carbon and Climate Observations and Modeling project (SOCCOM), and she currently serves as Chair of the NOAA Science Advisory Board’s Climate Working Group.

Department of Hydrology and Atmospheric Sciences

Christopher L. Castro is UA Professor in the Department of Hydrology and Atmospheric Sciences. His doctoral and postdoctoral work applied a regional atmospheric model to the investigation of North American summer climate. His research group’s current work focuses principally on physical understanding and predicting climate in North America through regional atmospheric modeling and analysis. His projects engage the operational weather-forecast community and water-resource providers in the Southwest. He is a former Fulbright scholar and has been recognized for research excellence in studying long-term changes in North American monsoon precipitation by the Strategic Environmental Research and Development program.
