The Earth Hour Web site tells us to "Switch off your lights for an hour on Saturday, March 28, 2020 at 8:30 pm your local time." If this were just about saving energy to show our support of the 860 million people across the world who lack access to electricity, it would make sense. But it is not. While Earth Hour has expanded to encompass other environmental concerns as well, ‘stopping climate change’ is still front and center as a primary rationale for the event.
