12:00 - 2:30
Latino/Hispanic Meeting Room B
100 Larkin St.
We live in the best part of the solar system for life to exist on Earth, not too hot and not too cold (the “Goldilocks” zone).
Since the 1800’s, however, the Earth has been getting hotter.
Scientists are no longer debating the reality of global warming -- it is happening.
This first part of the three-part series will explain the physical science of Earth’s normal heating and cooling, and the factors leading to the increasingly rapid rise in temperature over the past 200 years.
No previous knowledge of math or science is needed to understand the illustrated presentation.
Please note: Attending all 3 talks will provide the best background to understand this environmental problem, as each talk builds on the information from the previous one. However, attending any one or two of them will give you some understanding of this increasingly worrisome problem for all inhabitants of this beautiful planet.
Instructor: Barbara-Ann G. Lewis, PhD
