Need help with my writing homework on The Consequences of the Rising Sea Level. Write a 1250 word paper answering; Thus it is deemed that natural factors contributing to global warming are very small as compared to activities that people engage in top change atmospheric concentration of greenhouse gases.
Rising of the Sea Level
The warming of the atmosphere has resulted in higher sea level because of land and lower atmosphere of a warmer climate result to heat being channelled into the oceans (Neumann, Yohe, Nicholle and Manion 12). Heating of materials leads to their expansion which is referred to as thermal expansion, thus the transfer of heat results to the expansion of seawater, which results in a rise in sea level. Warm temperatures might result in the following effects on the earth’s surface’s natural resources, in the ice lands and oceans. When non-polar glaciers melt, they release water might flow into the ocean, thus contributing to a sea-level rise.
Glaciers are highly sensitive to change in climate and, therefore, melt at a very fast rate, and the water flows to oceans, and the effect is increased in sea levels (FEMA 10). Ice increases from snowfall and is balanced by ice loss from melting and the discharging of glaciers in the Greenland (Archer 38). Forecasts show that the increase in melting from higher temperatures will cause an increase in precipitation. Thus, the changes in the ice balance will add water to the ocean, hence contributing to the rise in sea levels. Almost all of Antarctica is covered by a sheet of ice, which is 2.5 kilometres thick and if the ice covering Antarctica was to melt, then there would be an over 60 meters rise in the sea levels. However, the increase of a few degrees in the Antarctic would not change the melting point of ice since it is so cold there and extremely high temperatures will melt down the ice. Though thermal expansion is not an obvious process than melting ice, weather professionals argue that it remains a major contributor of projected sea-level rise in the 21st century.It has been difficult for scientists to be precise with sea-level forecasts since there are several uncertainties. The first one is greenhouse gas concentrations, and scientists agree that depending on the levels of increase in these gases will determine the future rise in atmospheric temperatures and consequently sea levels. However, this depends on several factors, for example, growth in population, use of energy and development of new technologies.
