The world's oceans are rapidly rising as waters warm and ice sheets melt. Coastal locations, like the San Francisco Bay Area, will be among the hardest hit by the rising tide.
Beyond sea level rise, San Francisco is slowly sinking at a rate of up to 10 millimetres per year in a process called subsidence.
All this incoming water will have devastating consequences for the area, where pricey real estate developments and clusters of billion-dollar tech companies may be forced to relocate.
Research group Climate Central has created a plug-in for Google Earth that illustrates how catastrophic an "extreme" sea-level rise scenario would be if the flooding happened now, based on projections in a 2017 report from the National Oceanic and Atmospheric Agency (NOAA).
The group's estimates are based on the worst-case scenario forecasting from NOAA's data, and it puts into perspective how dangerous the situation could get for San Francisco, Silicon Valley, and the Greater Bay Area.
While Apple's brand-new office in Cupertino will be safe, companies based in Menlo Park, like Facebook, will be totally inundated (assuming these companies stay in the same place for the next several decades).
Check out below which tech companies could have their offices flooded if climate change continues unabated.
