Aliso Canyon, Methane, and Global Climate

The Aliso Canyon underground storage facility for natural gas in the San Fernando Valley—the fourth largest of its kind in the United States—had one of its wells blow out on October 23, 2015, leading to a large release of methane. In a recent conversation, Professor Paul Wennberg discusses enormous methane and carbon dioxide (CO2) emissions, and their troubling implications for global climate. “If we could really knock the methane emissions back to what they were before people started emitting methane, it would be a large change. It would be a half a watt per meter squared. The total global warming would drop by around 25 percent,” Professor Wennberg explains. [Caltech story]
