impacts of sea level rise
Impacts of Sea Level Rise
There are two main reasons why sea levels are rising, firstly as air temperatures rise (due to climate change) the water in the oceans is warmed and expands. This process is called thermal expansion. The second reason being that as ice sheets and glaciers melt, they increase the amount of water in the oceans. Both of which are rather straightforward.
Scientists have shown that in the past there have been periods of significant sea level change due to natural factors. However, current measurements and predictions indicate that human activity is now the main driving force.

Sea level rise is not a uniform process, it totally depends on the region there are rapid variations from region to region, there are many factors that affect the level to which the sea rises, with prevailing winds, ocean currents, and land rebound or subsidence being important considerations. For example Scotland might not see any significant sea level rise in the near future, whilst somewhere like the Chesapeake Bay, USA may see a rise above the average level.
Following a recent report ‘climate change scientists predict that for each one degree Celsius of increase in global temperature, sea levels will rise 2.3 meters. They say their estimate may be accurate for as long as the next 2,000 years.’
This is not very encouraging information, especially when, in the same report, according to the World Bank, global temperatures may rise as much as 2 degrees Celsius (above the ‘pre-industrial era levels’), over the next 30 years or so, due to increasing concentrations of greenhouse gases in the atmosphere.
This will mean that generally, the sea levels will rise unavoidably by 50cm by the year 2050. It will have pronounced effects at the equator, especially around densely populated areas such as Bangkok, Thailand and Ho Chi Minh City, Vietnam. Scientists predict more intense tropical storms, food shortages, dangerous heat waves, and eventually flooding that could

    With admirable foresight, the Internet Engineering Task Force (IETF) initiated as early as in 1994, the design and development of a suite of protocols and standards now known as Internet Protocol Version 6 (IPv6), as a worthy tool to phase out and supplant IPv4 over the coming years. There is an explosion of sorts in the number and range of IP capable devices that are being released in the market and the usage of these by an increasingly tech savvy global population. The new protocol aims to effectively support the ever-expanding Internet usage and functionality, and also address security concerns.…

    Where we live in Southern California the land has been rising for the past million years due to faulting. With more ice at our polar regions we have lower sea level, and as that ice melts - the sea level rises. This back and forth pattern of rising and falling sea levels affects the coastal environments, as neither are steady processes.…

    It is just like a cup of soda with ice. Over time the ice melts into the soda which make the soda watered down. The same rules apply; the ice caps are the ice and the ocean is the soda. The ice caps break off from the mainland, then drop into the ocean and melt, adding more water. Sea levels rise about .13 inches a year according to the National Geographic website. That does not sound to alarming does it? Well over the past century the ocean has rose 4 to 8 feet. Also the CBS Miami website says with the way sea levels are rising not just Miami, but all of south florida will be under water by 2025. With air pollution contributing to rising sea levels everybody in south Florida is in…

    In the Great Gatsby, Fitzgerald uses language to illustrate how calm and tranquil Gatsby’s death was. In chapter 8, Tom spent the day after the accident with Gatsby and felt as if he just needed to simply talk to him. Whereas, George had come out of his seclusion and began to think about the events that occurred the previous night. He vowed he would find who that car belonged to and that he would do something about it. As the day progressed, Nick felt tense as if knowing something would happen, so he went to see Gatsby directly. His death was so serene, there was “barely perceptible movement” and wind which “scarcely corrugated the surface.” These words that demonstrate little movement, reflect on Gatsby’s demise. The “barely perceptible movement,”…

    The sea levels rising could destroy ecosystems by removing or increasing certain species in a certain area of the ocean. Especially coastal areas. “Rising water levels will have serious impacts on marine ecosystems. The amount of light reaching offshore plants and algae dependent on photosynthesis could be reduced, while coastal habitats are already being flooded”(Climate change impacts on the marine environment, pg 3, par 3). The flooding of these habitats is dangerous because it disrupts the flow of a lot of organisms that keep the ecosystems in balance. “Wetlands normally grow vertically fast enough to keep up with sea level rise, but recently the sea has been rising too fast for wetlands to keep their blades above water. Coral reefs and sea grass meadows are also in danger of “drowning” since they can only photosynthesize in relatively shallow water” (Fujita, pg 2, par 4). With the sea levels rising so fast, it could also begin to effect more than just…

    Many cities across the world are located at or below sea level. Even with dams, dykes and dunes, these cities can be prone to flooding. The global climate change is causing sea levels to rise which is creating a domino effect across the world. According to Vanessa McKinney, author of Sea Level Rise and the Future of the Netherlands, the earth’s Polar Regions are becoming much warmer…

    This is important to consider because “in the 20th century, the world’s average surface temperature rose by approximately 1 degree Fahrenheit, the fastest rate in any period over the last 1,000 years” (Source A). Although this one degree change may not seem drastic, over the coming years it can dramatically increase the temperature of the earth if the human population does not intervene. This is why regulating the changes in surface temperature is so important to global warming policies. In addition to this, the graph is Source B clearly depicts that the measured ocean temperatures over approximately 150 years, from 1880-2004, have increased rapidly, especially since the mid-1900’s (Source B). This supplements the data from Source A, and clearly interlinks changes in surface temperature to global warming. Lastly, it was show that the “best estimates suggest an average temperature increase of 1.4-5.8 [degrees Celsius and] a sea-level rise in the order of a metre…” (Source E). No matter what the increase is, the fact that the surface temperature on the Earth is increasing is a wakeup call to the human race on how their daily lives are contributing to global warming. Changes in surface temperature are important to consider when making policies that affect global…

    The rise in sea level may be the end for us all as we know it. With the sea rapidly closing in there is no real quick solution. Over one thousand people have already been affected. Examples of this would be the flooding in Jakarta or the lack of crops in Egypt. In addition, how does rise in a sea level complicate the struggle for existence for humans and how does the rise in sea level affect how an overall population can survive and how it will repopulate.…

    The sea level has been rising globally for the past 10,000 years before anthropologic influence, but due to large amounts of CO2 release the sea level is now rising rapidly. The warming of global temperatures over the past century that continues to grow with time causes this rise in sea level. Because of this growing global temperature, the ice caps are melting rapidly and will continue to melt at a faster rate. “…Even if we could stabilize concentrations of GHGs, we are already committed to significant warming and sea level rise no matter what scenario we follow (Gerald A. Meehl et al).” At this point, it would be impossible to avoid increased sea levels due to this melting. This melting means that many areas of low elevation will experience major flooding. Sea levels could rise by several meters in the next 100 years, leading to major land loss. Flooding can also lead to declines or shifts to local fisheries, leading to possible protein shortages in poorer populations, leading to famine. This could put many lives in jeopardy and could alter many coastal ecosystems, leading to loss of coastal infrastructure, coastal erosion, loss of human life, and the extinction of several species unable to adapt or move to another adequate…

    There has been a 6 metre rise in sea level between 2010 and 2097 with the rate of the rise is only getting faster. Over the past year there has been a 7.9mm rise in sea level which is more than double the expected rise. Scientific research suggests that 37% of the sea level increase has been due to thermal expansion, 53% of sea level increase due to the melting of the Antarctic Ice sheet and The Greenland Ice sheet and 9% of the sea level increase is from various other factors.…

    Sea levels rise more as the temperature rises because as water heats up the molecules expand (Sea). As small as 0.14 inches may sound, its effects can be devastating for coastal habitats. If conditions continue as they are, then the sea levels will rise at lethal proportions. As tested in a recent study, oceans can be expected to rise 2.5 to 6.5 feet in the year 2100; this is enough to flood many cities off of the US East Coast (Sea). Sea levels are also anticipated to rise due to melting ice caps and glaciers. It is uncertain on whether or not the world's two major ice sheets, Greenland and Antarctica, have been growing or lessening, due to their vast size (Polar). If a complete meltdown of a Greenland ice sheet were to occur, then the sea level would rise up 23 feet, which is enough to submerge all of London (Sea).…

    Therefore we can say that if we don’t start solving this problem with a quick and an effective solution, we are going to face a major catastrophe. Because of global warming temperatures are rising and the most striking evidence of global warming is a data that shoes the rapid and massive increase of temperatures in the past century. The temperatures on Earth started to rise more and more when metal industries started to develop and expand a lot, and also when many big forests were burned and destroyed. The ten warmest years that happened on planet Earth, occurred during 1997-2008, according to NASA’s Goddard Institute for Space Studies. With the help of the modern technology and science, many world known scientists from all over the world were able to calculate that, the rising temperatures observed from 1978 have nothing to do with the rising temperature of the sun at that time. They were able to see that the energy reaching the Earth from the Sun is not causing the rise in the temperatures and that Earth’s warming was not due to changes in the Sun. Another problem that is caused by Global Warming is the rising sea levels. The sea level has increased over 8 to 9 inches, and the increasing rate is not stopping. Authors of the IPCC reported…
