Bishop Museum will join the global effort to combat climate change by going dark in honor of Earth Hour this Saturday from 8:30 to 9:30 p.m. During that time Bishop Museum will turn off all non-essential lights.

On March 28, millions of people across the globe will turn off their lights for one hour.

Bishop Museum has enlisted its more than 200 employees to go dark during Earth Hour along with its members, which total 8,300 households.

"For the past several months, Bishop Museum staff has worked to lower our energy costs and in the process we are more aware of our carbon footprint," said Timothy Johns, president and CEO. "Earth Hour is one more step to not only save energy but to work together in taking care of our home – our Earth."

In the Science On A Sphere exhibit at Bishop Museum, visitors can view a six-foot globe to learn about the effects of Climate Change and Global Warming, and have a chance to calculate their carbon imprint. Science On A Sphere shows are provided daily at the museum at 2:30 p.m. in the J. Watumull Planetarium Lobby. www.bishopmuseum.org/planetarium/sos.html.
