Earlier this month, a remote monitoring system in Hawaii recorded the first time in human history that the daily average for carbon dioxide levels in the atmosphere hit over 400 parts per million (ppm). Crossing the 400ppm line is not inherently meaningful, other than reminding us that we are on a path to a place we don’t want to go, writes Daniel Vermeer, executive director of the Center for Energy, Development and the Global Environment at Duke University’s Fuqua School of Business.
