I will present "Earth, Orbit, and Climate." My presentation is a illustrated look how the science of astronomy contributes to our understanding of climate change. I cover the Sun, the greenhouse effect, climate sensitivity, paleoclimate data, and Earth's changing orbit. Below is a sample from the section describing the greenhouse effect.
After the presentation, the Temecula Valley Astronomers will have a few telescopes set up for some observing of the moon and Saturn until the library closes.
