Sun and Climate with Dr. Christoph Keller

11/14/2023 @ 6:00 pm - 7:00 pm



Dr. Christoph Keller, Director of Science at Lowell Observatory, will be speaking on the subject of the Sun and Climate at the Jim and Linda Lee Planetarium, Prescott, AZ.

The Sun enables life on Earth. If the luminosity of the Sun changes, then the Earth’s climate changes. Dark spots on the Sun have been known for thousands of years. Do sunspots reduce the Sun’s luminosity and lower the Earth’s temperature? Amazingly, the sun’s luminosity increases when it has a particularly large number of sunspots. This talk explains the cause of this surprising fact and shows how the sunspot cycle can be traced back thousands of years and how it affects the Earth in various ways.
