According to a study released March 7, half of San Francisco International Airport's runways could sink underwater by 2100, The New York Times reported.
The study, published in Science Advances by Manoochehr Shirzaei of Arizona State University and Roland Bürgmann of the University of California, Berkeley, reveals that sea level rise poses more of a threat to the Bay Area than previously thought. The reason? A phenomenon known as subsidence, or land sinking.
