Sea Levels Expected to Rise Through 2100

A report on how global warming, melting the ice in the Arctic, Antarctic, and mountains, will affect California. Conservative estimates are 1.0 to 1.4 meter increase in sea levels, by the year 2100.

From Pacific Institute: Sea Level Rise

• Under medium to medium‐high greenhouse‐gas emissions scenarios, mean sea level along the California coast is projected to rise from 1.0 to 1.4 meters (m) by the year 2100. Maps for the entire coast of California demonstrating the extent of the areas at risk are posted at www.pacinst.org/reports/sea_level_rise
• A 1.4 meter sea‐level rise will put 480,000 people at risk of a 100‐year flood event, given today’s population. Populations in San Mateo and Orange Counties are especially vulnerable. In each, an estimated 110,000 people are at risk. Large numbers of residents (66,000) in Alameda County are also at risk.
