Retired professor Denise Barkis Richter, Ph.D., will present a virtual gallery talk, “Climate Change is Real: What You Can Do to Help Get Our CO2 Emissions to a Safe Level" at 2 p.m. Saturday, Aug. 29 to coincide with Bihl Haus Art’s current exhibition "Hot Pursuit: A Visual Commentary on Climate Change" by Sabra Booth. Listen to Richter speak at www.BihlHausArts.org.

In her talk, Richter will address the clear and present danger of the climate crisis, “which is going to dwarf coronavirus if we don't get a handle on it. The safe level of CO2 in the atmosphere is 350 ppm; we just surpassed 415 on July 4,” she said.

The exhibition "Hot Pursuit: Visual Commentary on Climate Change" by Sabra Booth is a retrospective environmental and climate change body of work produced by the artist over the past decade. It continues through Oct. 24.

Richter is a recently retired professor of journalism and mass communication at Palo Alto College, where she served as chair of the college's Viva Verde committee. Over the past 11 years, Palo Alto College rescued more than 550,000 pounds of paper, cardboard, plastic, metal and glass from going into the city's landfill. In addition to recycling, the Viva Verde committee championed a wide range of sustainability initiatives, such as greening the curriculum, tree planting, nature photography, water conservation, air quality improvement, and solar energy.
