Because the natural gas infrastructure is so vast, it is not possible to measure every leak from every faulty valve or fitting. Indeed, we don’t even have accurate estimates of the total number of valves and fittings. The best way to estimate the total amount of methane emissions from the natural gas infrastructure is to perform as many measurements as possible from as many different types of components as possible. The reason that one has to perform hundreds or even thousands of measurements from each type of equipment is so that you can capture the high-emitting sources (the so-called super-emitters), which are low in number but their emissions are so high that they can account for 50% to 80% of the total emissions.

Santa Barbara County residents and businesses may be getting greenhouse-gas-free electricity from renewable sources in a year or so after the Board of Supervisors voted to join the Monterey Bay Community Power Authority. Supervisors voted 4-1 Tuesday, with 4th District Supervisor Peter Adam dissenting, to obtain the county customers’ electricity through the Monterey Bay Community Choice Energy project, although the board will have opportunities to pull out before the power starts flowing to customers, probably sometime in 2021.

This week, I’m on the road attending the American Meteorological Society (AMS) conference in San Diego. One of the courses that I will be taking is “Understanding the Extent of Climate Change in Extreme Weather Events”. This class will be taught by Admiral (Ret) David Titley. He is the former oceanographer and navigator of the Navy. He is now a professor at Penn State and founding director of Penn State’s Center for Solutions to Weather and Climate Risk.
