Melting Ice Caps Research Paper

Coastal cities all around the world are quite precious to the countries to which they belong. Small and large cities on the water can accumulate massive amounts of income for countries, with most of it coming from tourists. Unfortunately, these cities are at risk of shrinking in size as a result of rising seawater levels. Along with less land for those cities to bring in money, it would cost millions of dollars to relocate the buildings and homes built there. Due to rising average temperatures of the earth, thermal expansion of water, along with melting ice caps, is causing the seawater levels to rise, which is threatening coastline cities such as New York City and Venice, Italy. There are many causes of rising sea levels, with one of the …show more content…

Unfortunately, the melting ice caps are another result of solar warming. Over many years, “the vast ice cover around the North Pole has shrunk due to global warming. This has led to rise in sea levels, which ultimately affects coastal regions” (“Melting Ice Caps Affect Coastal Regions”). In this article, the author goes into depth on the results of the melting ice caps. Another effect of global warming is the fact that it has led to the shrinking of the “vast ice cover around the North Pole.” Consequently, when the ice melts it adds more water into the sea, leading to higher water levels. Adding to this, the “melting glaciers add new water to the ocean, raising sea levels” (“Sea Level Rise”). The author states that the “melting glaciers add new water” to show that when the water stored in the frozen glaciers melts, it releases water that was not originally in the ocean. A factor of these increased rates of melting ice sheets has been termed dynamic thinning. In this process, “warmer ocean temperatures melt the underside of ice shelves, just as warmer atmospheric temperatures increase surface melting” (“Sea Level Rise”). This comes as another result of solar warming, as that is what causes the seawater temperatures to increase in the first place, which in turn “melts the underside of ice shelves.” This solar warming does not only affect ice caps through the …show more content…

New York City is greatly threatened by rising sea levels as “about 400,000 New Yorkers live within the current 100-year floodplain” (Gerken). The “100-year floodplain” that Gerken mentions is how much of the city is at risk if the city is to flood. Showing if the city is to flood, or if current calculations of sea level rise is to continue, 400,000 people in just New York will need to find new homes. If this were to happen, it would be extremely costly to the city, and there would be less room for revenue from tourists. The problem of sea levels rising is not only a problem in the United States, it is also a problem all around the world, specifically in Venice, Italy. Any increase in sea levels can pose a large problem for Venice, and the people of Venice are working to find a way to prevent the effects that rising sea levels have. Over the centuries, “the city’s leaders and residents have dealt with rising sea levels either by demolishing old buildings and erecting new ones on higher, impermeable-stone foundations, or by raising the entrances to buildings that line the dozens of canals” (Keahey). Keahey states how the people of the city are working together to try to make the rising water levels not do as much damage. They are doing so by demolishing old buildings and rebuilding them on “higher, impermeable-stone foundations” and by “raising the entrances to buildings.”
