Organization, jobs, budget This results in ocean levels rising worldwide. In a set of targets guided by Gov. The Sea Level Inundation polygon feature class contains the field SLR_CODE_NUM (Sea Level Rise Code), which stores a short integer (0-10) that represents the amount in feet of projected sea level rise required for that area to become inundated. Dubbed The Ocean Is Moving In, the campaign features Science has shown that the changing climate will result in a gradual and permanent rise in global sea levels. Among these are the impending impacts of climate change, including the hazards that rising seas pose to Californias coast. The Sea Level Rise Technical Report provides the most up-to-date sea level rise projections available for all U.S. states and territories. NASA. But the sea-level rise is something that could affect all Californians because of where that rising seawater would end up: the Central Delta. For every foot of global sea-level rise caused by the loss of ice on West Antarctica, sea-level will rise approximately 1.25 feet along the California coast.
