Rising sea level can be caused by a variety of factors and can have an effect or influence even more. Future changes in sea level may impact human populations around the world and many other aspects of life on Earth more than many initially thought. The U.S. coast of the Gulf of Mexico is on track to be one of the most impacted by further sea level rise and the outcome could be detrimental to the entire coastline.

The rise of sea levels are projected to increase warmer waters from one and a half to two degrees in Central North Pacific in 2050, 1.9 to 2.6 degrees in Northern Islands, and also two to five degrees in the Caribbean at the end of this century. This rise of temperature decreases the life of ecosystems in the ocean and resulting in less freshwater for

Besides the direct effect of sea level rise, coastal flooding may also be a more prevalent and severe issue. For example, “sea level rise of two feet, without any changes in storms, would more than triple the frequency of dangerous coastal flooding throughout most of the Northeast” (Horton 374). The higher seas would increase the initial level, so that the flooding level would be much greater, especially during hurricanes. Recent hurricanes have become a good example of how much damage can occur to both humans and animals. For example, much of the coastal infrastructure is in danger of damage, which can affect commerce and the public’s health and safety: “In New York State, two feet of sea level rise is estimated...To flood or render unusable 212 miles of road, 77 miles of rail, 3,647 acres of airport facilities, and 539 acres of runways” (Horton 379). This loss of infrastructure may occur in every coastal Northeast state, especially in the south. In these southern Northeast states, the land is flat, which makes them easier to inundate with water. In addition to infrastructure, transportation is also at risk, with much of the major highways (I-95) and trains (Amtrak) at risk of coastal damage (Horton 380). More affected by sea level rise, ecosystems near water may be permanently damaged in upcoming years, and according to Rob Deconto, a climate scientist at University of

Sea level has risen 3.4 mm per year due to climate change. This can have devastating effects on humans, plants and animals, and their habitats. Climate change has become a colossal problem considering it can leave countless humans stranded or starving, that are in need of assistance. It has also caused distrust or rifts between countries over who caused it and whose responsibility it is to pay for the damages it has caused. The economy of places on earth will be suspected to plummet as a result of rising sea levels and temperatures provoking animals to relocate and countries to lose their major exports, or suffer from the increase in prices for their imported goods. The U.N. believes that this is problem is in need of a solution. The world

However, issues the occur with rising temperature involve more severe floods, storms, droughts and fires which could then lead to higher death toll in human and animal life because for some animals it will be too hot to live. Due to this rise in Temperature Sea, level has increased dramatically and scientist estimate that the sea will continue to rise 15-95 cm by the end of the century. Sea levels are rising because two reasons. First with increasing average global temperatures, the water in Earth’s oceans expand in volume. This occurs because, when heated the molecules that make up a body of water move more rapidly and collide more often. The second reason is when glaciers and ice sheets melt the water that had previously been frozen the glaciers will melt and release the water cause more enter the oceans and

The Sea Level has increased over the past 200 years as average global temperatures have increased. The rise is due to two factors, the freshwater being added to the oceans from ice melt in the cryosphere, and the thermal expansion of the oceans due to rises in sea temperature. The sea level has risen 6 to 8 inches in the past 100 years. It is predicted to rise another 50 to 90 centimeters in the next century. As the sea level rises it’s jeopardizing rapidly growing coastal communities, which causes evacuation in some areas causing people to lose their homes. Sea level is the effect

The combination of these and other trends was an estimated average sea-level increase of 1.5mm per year between 1961 and 2003, which reached 2.4mm per year in the decade from 1993 to 2003. The decades prior to this trend showed only minor fluctuations in sea-level, suggesting that the current rate exceeds what could be caused by natural cycles. While the exact impact of rising oceans is difficult to determine, it is certain that the consequences will include some degree of flooding, integration of salt water into water tables, and a loss of land due to coastal erosion and submersion.6

Rising temperatures are causing melting glaciers, which cause rising oceans. Rising oceans will envelop entire coastal cities, killing or displacing millions of people. Our food sources will dwindle; entire species of animals will become extinct as we destroy their homes to rebuild; and as our population skyrockets, an unimaginable number of humans will be left homeless, starving, and sick.

Sea level rise is also a significant factor of erosion because as the sea level has risen over time, beaches and barrier islands have moved, transporting sand in the process. Sea level rise is a long-term process of coastal transformation as sand is steadily removed from beaches and barrier islands and transported to other areas, creating less protection for beaches and estuaries. As sea level rise continues to increase along the South Carolina coast, erosion by coastal flooding will become an even greater problem (United States 1.1). One study on the correlation between sea level rise and erosion concluded that sea level rise does increase erosion rates if nothing else due to the fact that “rising sea level enables high-energy waves to reach farther up the beach and redistribute sand offshore” (Leatherman 55). Human activity through construction also has a negative effect on beaches and erosion, for example the building of structures such as seawalls, jetties and groins have negatively effected the movement of sand, thus not allowing the proper amount of sand to reach the beaches and barrier islands to replace the moving sand due to other factors (United States 1.1). Erosion is a natural process of coastal change due to many factors, but human activity and development can increase the rate at which

What humanity faces from the ramifications of this issue is immense. This research article will seek to convey and articulate if climate change has affected the rise of ocean levels, and if so what are the detrimental affects on coastal communities. This article will also reveal what specific regions and events that are happening that are elevating ocean level rise. The objective of this research article is to inform people about the plight that humanity has found itself in and how to prevent ecological damage and along with that prepare for the coming tide.

As the sea rises, the waves push more into the coast and drag the coastal deposits back into the ocean. Similar to hill sides and mountain sides that experience erosion when they have low or no existing vegetation to protect from the eroding effects of the weather, coastlines face the issue of erosion as well. If this were to happen, the recession of coastline ecosystem may lead to more damaging effects due to the sea and its weather on the nearby land area and people.

Do the beaches need to be saved? Why should beach eroition be such a big deal? As beach erosion continues the beaches get narrower and narrower witch cause them to increase rising the tide above usual and causing flooding issues. This is also the cause of some houses falling near the ocean.

Rising sea levels have caused tide lines to be increased by approximately 9.15 feet (Freedman, #3). This increase in tide makes all surrounding land very susceptible to damage, if a hurricane was to occur. Since studies show that during normal waters, tides can get this high, there is an approximation that water can reach up to 100 feet of just wave water in the event of a hurricane (Carey, #1). Also, because of global warming, sea levels are expected to rise an additional 2 feet in the next century (Freedman, #4). This is due to the melting of icebergs, ice caps, and arctic snow that eventually ends up in the oceans. With this additional 2 foot rise, coastal waters are expected to hit an all-time high. In addition to the rising of the tides, the actual area of the ocean will expand, causing any coastal industries, neighborhoods, or developments, to be highly susceptible of being underwater by the next century.

A. Rising sea levels could flood many South Seas islands and swamp large parts of Southeast Asia.

The deterioration of coral reefs is mainly linked to human activities – 88% of coral reefs are threatened through various reasons as
