MENLO PARK, Calif. -- Facebook is one of the well-known companies in Silicon Valley's technology mecca that will face the effects of climate change in years ahead. Others located near the water here include Google, Yahoo, Dell, LinkedIn, Intuit, Intel, Cisco, Citrix and Oracle. Scientists predict seas will climb as much as 16 inches by midcentury and 65 inches by 2100. Storms are expected to intensify and occur more often. Both pose dangers for businesses and homes near the bay. Yet Silicon Valley, a place that in many ways creates the future through technological advances, largely has yet to tackle the repercussions that climate change will bring in years ahead, several people said.
