Lawns provide surprising contribution to L.A. Basin’s carbon emissions

The Los Angeles Basin is often thought of as a dry, smoggy, overdeveloped landscape. But a new study led by NOAA and the University of Colorado, Boulder shows that the manicured lawns, emerald golf courses and trees of America’s second-largest city have a surprisingly large influence on the city’s carbon emissions.

Tracking fossil fuel emissions with carbon-14

Researchers from NOAA and the University of Colorado Boulder have devised a breakthrough method for estimating national emissions of carbon dioxide from fossil fuels using ambient air samples and a well-known isotope of carbon that scientists have relied on for decades to date archaeological sites.
