Osher Lifelong Learning Institute (OLLI) presents this 2 hour in person course with speaker Dr. Cathy Whitlock.
Please note: This course program requires a 2025-2026 OLLI at MSU Membership
Climate change is on everyone's mind, but how much do we know about the science? Is global warming something new, or has the climate always changed?
This lecture will discuss ancient climate transitions, including their causes and past consequences; compare the geologic record with what's happening now; and examine different future climate scenarios for our region depending on societal action. It's intended to be a primer for folks wanting to increase their knowledge of this critical, complex issue.
Course Takeaways
A better understanding of the science of climate change, drawing on these concepts:
•
Climate change has occurred throughout geological time for various reasons. In this sense, it is nothing new.
•
Periodic changes in the Earth's orbit around the Sun cause ice ages, including the one that ended 15,000 years ago.
•
The current warming trend in Montana is due to increased greenhouse gases in the atmosphere, primarily from burning fossil fuels. Levels of CO2 haven't been this high in 3.3 million years!
•
Plausible pathways for future climate change depend on societal choices, population growth, energy use, technology and land use.
