Human-driven climate change is putting an enormous amount of stress on coastal and estuarine environments from all directions.

ECOLOGY, THREATS AND MANAGEMENT OPTIONS FOR SMALL ESTUARIES AND ICOLLS vii SUMMARY Intermittently closed and open lakes and lagoons (ICOLLs) constitute over 60% of coastal waterways in south-eastern Australia yet, in comparison with large estuaries, relatively little is … Dredging. In the next hundred years, taking into account the ongoing sinking of land in some coastal areas, net sea-level rise could exceed six feet. The largest anthropogenic threat to estuaries is conversion by draining, filling, damming, and dredging. As they are consumed by plants and animals, they accumulate in the tissues of living things. Sediments infill estuaries and can smother marine life. Aggressive invasive weeds have changed the character of estuaries, e.g. Protect Estuaries #10 -Take action! The estuaries serve as great ecosystems for humans, but the estuaries themselves are at risk of pollution. In estuaries, the salty ocean mixes with a freshwater river, resulting in brackish water.Brackish water is somewhat salty, but not as salty as the ocean. Migrating birds such as geese use estuaries to feed and rest. So, what else threats to ocean ecosystems? Pollution threat to estuaries. Already sharply reduced in acreage, coastal freshwater wetlands are especially vulnerable to rising sea levels. Estuaries. Estuaries act as barriers against ocean waves, which can erode the shoreline and cause major damage to homes and businesses. Sea level rise threatens to inundate many coastal wetlands, with little room to move inland because of coastal development. This Story Map provides a broad overview and explanations of estuaries and their importance in California, as well as how they're affected by climate change, sea-level rise, and other threats, and what solution are available.
