NOAA's Sea Level Rise map viewer gives users a way to visualize community-level impacts from coastal flooding or sea level rise (up to 10 feet above average high tides). The Effects of Sea Level Rise Program . However, along most U.S. coastlines, sea levels have not risen so much that even with this lunar assist, high tides regularly top flooding thresholds. This results in ocean levels rising worldwide. The projections show a sharp distinction at Cape Mendocino in northern California. Such strategies consist of continued use . The nature of that change will depend on both the rate of sea-level rise . Projected sea-level rise poses further threats to several endemic protected tidal marsh species such as the salt marsh harvest mouse, California Ridgway's clapper rail, light-footed Ridgway's rail, Belding's savannah sparrow, and California black rail that are listed as federally endangered or state threatened species. So half of the 18.6-year lunar cycle counteracts the effect of sea level rise on high tides, and the other half increases the effect. UC Berkeley researchers have cautioned for some time that climate change-driven sea level rise will inundate much of the Bay Area's low-lying regions, but a new study indicates the threat is particularly acute for landfill developments such as Treasure Island and Foster City. Here are the main impacts: Sea Level Rise - As the planet warms, seawater will expand, ice sheets will melt and water levels will rise, flooding beaches.Normally, beaches might naturally migrate inland in response, but oftentimes beaches are trapped between rising seas and structures like buildings and roads, leaving them nowhere to go. CNN meteorologist Tom Sater shows "astonishing" images of what that might look like. Sea-Level Rise Could Make Rivers More Likely to Jump Course.
