Rising sea levels are predicted to submerge many coastal areas around San Francisco Bay by 2100, but a new study warns that sinking land - primarily the compaction of landfill - will make flooding even worse. Using precise measurements of subsidence around the Bay Area between 2007 and 2011 from state-of-the-art satellite-based synthetic aperture radar (InSAR), scientists mapped out the waterfront areas that will be impacted by various estimates of sea level rise by the end of the century. They found that, depending on how fast seas rise, the areas at risk of inundation could be twice what had been estimated from sea level rise only. [Source: University of California, Berkeley]
