Recommended: The effects of sea level rise
Sea levels have been on the rise since 1880, steadily increasing every year, as seen in figure 1 provided by the Environmental Protection Agency (EPA). Globally, sea levels have risen 10-25cm (3.9 - 9.8inches) in the past century due to water input from melting ice caps (Hopkinson et al.). Sea level rise is most prominent on the east and west coast. On the east coast, sea levels have risen anywhere from six inches to over eight inches. Over on the west coast, specifically in the Southern California region, sea levels have risen 0.01 inches up to two inches according to the web article, Climate Indicators in the United States, published by the EPA. This climate change significantly affects the inhabitants of coastal areas being that nearly 53% of the United States population resides there (Crossett et al. 2004).
Increased sea levels can give way to a variety of problems: rapid coastal erosion, shoreline change, loss of natural protective barriers, saltwater intrusion into aquifers and surface water, changes in tidal prisms (volume of water in an inlet between high tide and low tide), and rising water tables ("Climate Change and Impacts of Sea Level Rise"). Ventura County is facing many issues with rapid coastal erosion and loss of natural protective barriers. Beach Erosion Authority for Clean Oceans and Nourishment (BEACON) conducted a study to evaluate the conditions of different beaches along the Ventura County coast (Barlow, "Coastal Erosion Problems Highlighted in New Study"). Port Hueneme’s western beaches (picture to the left) are losing three to five inches per month due to sea level rise pushing beaches farther back.

The amazing part about the steps being taken to try to save the Chesapeake Bay is how much scientists and people who carry out legislation in the local and state governments are working together to try and create policies on businesses and people to
The effect of sea level rising is especially challenging for the population that lives in low-lying coastal communities, such as Miami Beach. The city is surrounded by sea. Miami Beach is linked to the mainland city of Miami through causeways, and it is an area that allocates much of the wealth from its art decoration and former celebrity playground standing. For them, funding does not seem to be a problem. However, the threat they are facing, cannot be entirely solved by money. Its sea level rising is at 9 millimeters a year, while there is only 3 millimeters on global average acceleration. If the sea level rises for 6 feet by 2100, Miami Beach city will get swallowed. When referring about sea level rising phenomenon, Miami Beach always acts as a ground zero example. Government leaders around the world are waiting to see how this rich living laboratory experiment place can avoid drowning. Below is a figure showing the sea level rising between 1900 and 2020 in Miami and Miami Beach
Out of the largest 136 coastal cities in the world, Vancouver ranked 11 in terms of future flood damage (ibid) creating concerns for the safety of the human population. The historic sea level rise in Vancouver is 2.0cm/50 years but has jumped to an expected one meter by the year 2100 (“Sea Level Adaptation”, 2013). Majority of Canadians will be living within 20km of the coast with approximately 80% of British Columbians living within 5km (ibid). It is projected that the number of people living near coastlines will increase while will raise the amount of the population vulnerable to climate change trends
Coastal erosion is a growing problem along the Gulf Coast. Louisiana is one of the coastal states most affected by coastal erosion. Ninety percent of wetland loss in the nation occurs in Louisiana, losing 25-35 square miles per year. At that rate, Louisiana will lose 640,000 more acres by 2050. Many factors contribute to this land loss, such as rising sea levels, subsidence, hurricane storm surge, cold fronts, and human interference. Cold fronts and hurricanes can both have detrimental consequences on the coast of Louisiana (Zhang 2004) (Restore or Retreat 2012). This research shows whether cold fronts or hurricanes have a larger effect on coastal erosion. The researcher will describe how historical and current satellite imagery help in determining the changes in the Louisiana coast. Based on previous research, the researcher believes that hurricanes have more of an effect on coastal erosion than cold fronts due to the high winds and storm surge.

The 2007 datasets accessible from ####. Four counties –Ozaukee, Milwaukee, Racine, and Kenosha, which are located southwest of Wisconsin and adjacent to Lake Michigan, were selected to evaluate the coastal resilience conditions. Also, from the datasets, five characteristics that well-represent shoreline protection and bluff conditions were selected for the mapping. The characteristics includes Shore Protection, Beach Class, Bluff Condition, Bluff Modification, and Coastal Line Classification (Non-Bluff Condition). Since the original GIS datasets only provide county-scaled data, however, in order to divide them into township/city-scaled ones several procedures of reformatting data within ArcMap were required.

One of the major effects of global warming is the rise of sea level due to thermal expansion of the ocean, in addition to the melting of land ice. Now there are dozens of land areas that sit well below sea level and the majority of those land areas are very well populated. At least 40 percent of the world 's population lives within 62 miles of the ocean, putting millions of lives and billions of dollars ' worth of property and infrastructure at risk. (Juliet Christian-Smith, 2011) This means if the sea level rises to the projected level of 25 meters (82 feet) half of the world will retreat back to the ocean. (Rohrer, 2007) Also rising sea levels means higher tides and storm surges riding on ever-higher seas which are more dangerous to people and coastal inf...

The oceans need to be protected because it is where life began and if not taken care of, life as we know it will end. When dangerous substances go into the ocean, ecosystems are suffer and become endangered along with lives of people and of marine life. Surfrider Foundation recognizes the importance of protecting and preserving the quality and biodiversity of the world's coasts because they are truly irreplaceable. There is also historical evidence of ocean pollution being present in the past, but the problem still lingers today. Heal the Bay discovered that,“Did you know there is a DDT and PCB hot spot off the coast of Palos Verdes? This superfund site (which indicates it's one of the most polluted places in the United States), is left over from a 1930's era chemical plant. Because DDT takes so long to break down in the marine environment, it persists to this day, contaminating certain species of fish. There are also highly polluted sediments in the Long Beach area, a sign of the heavy shipping in the port. Heal the Bay works on developing effective capping and removal plans to keep those toxins from spreading” (Heal the Bay). DDT is still highly concentrated in the South Bay area and still contaminating different species of fish. Even after more than 80 years DDT, a toxic insecticide, is still very concentrated and during upwellings, DDT particles come back up and continue to harm marine life. If humans are careless about what is thrown on the floor or sprayed on lawns, it can lead to disastrous affects when it comes to the condition of the ocean's ecosystems, and can endanger life itself leading to a problem that only we can mend.
