KEEPING UP WITH GLOBAL WARMING: The Problem that Won't Go Away

KEEPING UP WITH GLOBAL WARMING: The Problem that Won't Go Away

A series of three illustrated talks on the science of the Sun, the Earth, and Its Atmosphere

Sunday, Aug 18. The Physics of Global Warming and Cooling

Since the 1800s, the Earth has been getting warmer. How do we know? Has Earth ever been hotter in the past? What does heat from the Sun have to do with floods and hurricanes? How are human activities related to Earth’s warming and cooling? We discuss the physical science of Earth’s normal heating and cooling, and the factors in the increasingly rapid rise in temperature over the past 200 years.

Sunday, Aug 25. How Humans Interact with Earth’s Atmosphere                      
This week’s topics: Scientists’ observations on rising temperatures and their effect on plants, animals, and human habitations. The Earth’s atmosphere, its composition, its role in transmission of the Sun’s energy to ecosystems, and the way clouds and dust particles affect Earth’s temperature. Methods used to study Earth’s climates in the past, including study of tree rings, pollen grains, and ice cores. 

Sunday, Sept. 1. Making Predictions

We review the evidence for continued warming of the Earth and the bases for predictions on how hot it will get and when. How are these predictions made? What effects will the increased temperatures have on nature as we know it and human quality of life as we know it? Can animals and humans adapt to higher temperatures? Can we bring the temperature of the Earth “back to where it was”?

Instructor: Barbara-Ann G. Lewis, PhD, Emerita Assoc. Professor of Environmental Engineering, Northwestern University

Location and time: San Francisco Public Library, Main Library, Latino/Hispanic Community Meeting Room B, Lower Level, 100 Larkin Street. Sundays: August 18, August 25, and September 1, 12:15 to 2:30 p.m.


Presented by the University of the Commons in association with the Business, Science & Technology Center of the San Francisco Public Library

    This summer, in China, nearly 50 cities ' temperature is up than 40 "C . The global warming is more and more closing to us.

    I'm very interested in how we can reverse global warming.
