The Global Ocean Water Levels

In a world divided by war, it is easy to overlook problems that affect all of mankind. The dramatic rise in ocean levels worldwide constitutes just that sort of problem. Although the fundamental problem of global warming has been given airtime and plenty of written-media coverage, the problem of rising sea levels seems to have met a

Due to Climate Change, the temperatures are increasing and there is a rise in sea

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

The rise of sea level and global warming has become a much more serious problem right now. This problem has drawn international attention, because higher sea levels in the future would cause great damages not only in coastal area, but also in various parts of the world.We have already seen thousands of people call and lead people to protect our environment and eliminate the emission of greenhouse gases. We could lose our planet as well based on what we did. We really have to take action to prevent the dangerous outcomes happen in the future, otherwise the more people’s life would be inflected and

Climate change is occurring and the impacts are already being felt in many regions. Studies conducted are typically done at the global, national or state level. The need to assess the threat associated with sea level rise at local level is important because local governments and private citizens are likely to be the first to deal with this potential problem.

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.

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.

Sea level rise is another area of concern for scientists and the global community with respect to climate change. Since the beginning of the Industrial Revolution, the sea level has risen about 8 in. and continues to rise about 0.14 in. per year (National Climate Association). IPCC has predicted a sea level rise of 1m. (~3.3 ft.) by the end of this century (O‘Rourke), putting small island nations such as the Maldives and at risk of losing their land, as well as cities in the US such as Miami, New Orleans, and New York. Once again, this number may seem insignificant, but when one considers that approximately 5 million people live within 4 ft. of the high tide areas in the United States; and 1 in 10 persons live in low lying coastal areas around the globe, then the numbers illustrate cause for great concern. An estimated 634 million people will be impacted by rising sea levels (Greenfieldboyce) and 1 billion people could be displaced from their homes by 2050 as a result of climate change (O‘Rourke).

In all, Earth’s oceans are diverse systems that all of life depends on for survival. The oceans act as a large conveyor belt; transporting varying volumes of water do different parts of the world. Any kind of alterations or disruptions to this conveyor belt causes regional sea levels to rise. These alterations are greatly impacted by anthropogenic climate change, the long-term alteration of earth’s climate as a result of human activities. The main ingredient behind climate change is the constant changing of global temperatures due to increasing levels of greenhouse gas emissions produced by humans. Mankind became intertwined with climate change during the industrial

The rising of Sea-Level’s is one of the major issues being focused on today. There have been several instances of impacts of the seas rising, in which certain locations could be submerged, disappear, flood more frequently. The rising of the seas is what causes for the presence of Coastal Resilience. The reason for this lies within the people.

One important direct precursors that lead to the rise in sea levels include the emissions of greenhouse gases that lead to warmer temperatures (Gornitz et al., 2004). These changes in temperature can result in devastating effects on ecosystems and their inhabitants (Gornitz et al., 2004). It is also important to mention that the temperature in Connecticut has been gradually warming, and reports indicate that the temperature increase is much greater than the increase in the other parts of New England (Gornitz et al., 2004). On the other hand, an indirect precursor that can lead to the rise in sea levels include land use, topography, and land cover that can account for the changeability in temperature. For example, the increase cutting down

The object of this paper is to analyze the academic integrity and reliability of two web-based archaeological papers. The first paper is “Sea level data archaeology and the Global Sea Level Observing System (GLOSS)” by Elizabeth Bradshaw, Lesley Rickards, and Thorkil Aarup and the second paper is “As the world warms: rising seas, coastal archaeology, and the erosion of maritime history” by Jon McVey Erlandson. The content of this paper will compare and contrast the validity of the information provided by assess the websites they are from and the background information of the authors. The strengths and weakness of each paper will be assessed based on how well they are written and which paper provides concrete conclusions on their issues. Each

The article addressed the increase in temperature over the years and claimed 2005 to be the warmest year in the last century. There is much fear, as temperature continues to increase, that possible ice reduction and melted ice sheets and glaciers in the Artic, Antarctica, and Greenland may occur and cause a rise in sea levels. If the Antarctic ice sheet melts, the sea level is calculated to rise two hundred feet, while if the ice sheet in Greenland melts, the sea level is calculated to rise seven meters, approximately twenty feet. The rise in sea level is affecting coastal areas. Many coastal areas are expected to sooner or later be flooded or below sea level. This can have terrible consequences for high populated coastal areas. Another problem that global warming may have on the world’s oceans is the possible change in the “global oceanic conveyor belt”. The conveyor belt controls the ocean’s currents which has impact on regional climate change. However, scientists have yet to agree on whether or not reduction of flow has

Accelerated sea level rise has been recognized as a key threat to the coastal zones,
