Throughout the Earth’s entire lifespan, it has been constantly changing. Oceans have flowed and dried, glaciers have risen and fallen, and multiple ice ages have occurred throughout time. However, the biggest change in the history of the planet has already made its marks, and the effects it has will continue to increase. Global warming is the greatest and most extreme climate change that the Earth has ever faced. It has changed the Earth’s surface and atmosphere in drastic ways that no other climate change has done in the past. Because of the extreme transition, all of the populations on Earth are also subject to the consequences that occur. This makes global warming an enormous threat to both Earth and all of the living organisms on its surface. Global warming is the greatest threat humanity has ever faced because of the continuous rise of the sea level, the decline in the amount of agriculture produced, and the extreme and devastating weather patterns.

A rise in the sea level is one of the significant problems global warming creates because of the inconvenience it generates and the danger it poses to humanity. Since global warming is the gradual increase in temperature, one of the results is the continuous melting of ice sheets and glaciers (Houghton 176). “Ice sheets covering half of Greenland and substantial portions of West Antarctica” are starting to melt due to the warming Earth (“Global Environment: Data”). Glaciers and ice sheets contain enormous amounts of water and as a result, the sea level is increased significantly. This increase in the sea level causes serious problems in coastal areas (“Global Environment: Part”). The sea “will erode coasts and cause more frequent coastal flooding. Some island nations will disappear” (“Global Warming: Featuring Articles”). With the constant eroding, the coastal population would have to abandon their homes and travel inland. This would be a great inconvenience as it would decrease the space available for comfortable living. Also, due to the rise in sea level, the flood threat would increase as well, which would lead to the loss of life and property (“Global Warming: Featuring Articles”). The majority of the land would be vulnerable because it would be below sea level, so it would be easy for the water to flood an area in coastal regions. This would lead to an increase in deaths because the people in these regions wouldn’t be equipped to deal with the sudden floods.
