Scientists Set Out to Map Climate Change like Weather The word "smog" was invented in California, so it seems appropriate that Los Angeles is now becoming one massive laboratory for studying carbon emissions. At an elevation of almost 6000 feet, Mount Wilson looms over the LA basin, a perfect vantage point for a new emissions monitoring station. Riley Duren, chief systems engineer at the NASA's Jet Propulsion Laboratory and manager of its Megacities Carbon Project , has more on plans to create a network of megacities to measure the dynamics of climate change.
