Over the last several decades, climate change has evolved from a polarizing discussion to what will likely be the largest collaborative research project of our generation. While many aspects of climate change are still misunderstood, there is little debate that the concentration of carbon dioxide in the atmosphere is rising at an alarming rate. This rise is considered the main cause behind an increase in global temperature, which has set in motion a chain reaction of climatic events.
Atmospheric carbon impacts the temperature of the Earth because it is a greenhouse gas. When visible light from the sun heats the surface of the earth, some of the energy is transmitted back towards the…show more content…
While thermal expansion is difficult to observe on a small scale, such as a glass of water, it can have a significant impact on a massive volume of water such as the combined oceans of the world. Melting land ice, the other major factor in the sea-level rise, is a more straightforward issue. As global temperature increases, land-based glaciers and ice will melt sooner and accumulate later. Naturally, this runoff will lead to an increase in the total amount of water in the ocean.
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 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.
The issue is that the sea water levels are rising as a result of warming oceans caused by climate change. The burning of fossil fuels has put lots of “greenhouse gases” such as methane into our atmosphere, causing more heat to be retained on the earth from the sun and overall warming the earth. The oceans absorb about 80 percent of the excess heat. Thermal Expansion is in effect as the sea levels rise. Polar ice caps and glaciers are melting due to global warming which is adding to the rising sea level. (National Geographic, 2017)
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.
Sea-level rise is one of the most significant effects of climate change. As global temperatures rise, ice in the polar-regions will continue to melt, dumping tons of additional water into the ocean. Warmer water temperatures will also lead the oceans to expand high projected rates of future sea-level rise. “These factors will cause sea levels to increase and swamp coastal areas all over the world” (Oceans and Sea Level Rise). Particularly, countries which are located in low-lying areas as well as islands, are concerned that their land areas would be decreased due to inundation and coastal erosion and, at worst, a large proportion of their population may be forced to migrate to other countries. Although flooding is an obvious consequence of rising sea levels, there are numerous other effects to consider. The current rising sea levels due to global warming are effecting the environment in a number of ways. (Oceans and Sea Level Rise)
