Effects of global warming
With the elevation in temperature, the temperature controlled balanced is disturbed. It has a deep impact on the water cycle, (Hydrologic cycle), promoted melting of glaciers, rise in sea level, increase in forest fires, increase in insect borne diseases, increase in diseases regarding temperature and alteration in severity of weather (YouTube).
Sea level rise
Warm temperature promotes the thermal expansions of water. Global warming promoted the thermal expansions of the sea water. With the thermal expansion, the volume of water increased and sea level risen. It is also due to the melting of the continental glaciers that filled oceans with more water (ravi). In the past 3000 years, the average rise in the sea level was only 0.4 to 0.8 inches. However, in the 20th century, the rise in sea level is about 8 inches (Hilderman, p61).
Arctic Ice melt
Arctic glaciers not only hold fresh water in ice form but also maintain the temperature of the region. With the increase in temperature the Arctic ice is melting and unable to cover the ocean (Astill, p2). The arctic ice traps the methane under the surface. As the ice is melting and the methane that is trapped under the ice surface is escaping (Hilderman, p61).
Lack of formation of ice on oceans surfaces in winter
Due to the global warming, the winters are ineffective and remain for shorter periods. The temperature in the winter season does not reach at a certain level. Thus, a tin layer of ice on the oceans form or in some regions there is not ice formation over the surface of oceans in winter season. The ice formation process in winters and ice melting process in summer is effective providing oceans creatures with oxygen. Without this process, the supply of oxygen to the oceanic creatures is becoming short and a large number of creatures die annually due to lack of oxygen dissolved in water (Hilderman, p62).
With the elevation in temperature, the number of forest fire incidents is increasing. The process is further reducing the process of photosynthesis and increasing the amount of carbon dioxide in the atmosphere. In U.S forest fires increased by 6% (Hilderman, p62). The warmer weather is making the grass lands to dry at a rapid rate. The dry grass promotes the forest fires. In some regions, it becomes uncontrolled each year.
Insect borne diseases
Due to the elevated temperature, the winters are becoming less effective, winters control the birth rate of insect, as insect larvae are unable to bear the winters. As winters are becoming less effective and temperature in the winters do not reach the healthy level, the insect larvae can survive the winters and thus the birth rate of the insect increases and thus the insect borne diseases increases. Mosquito borne diseases are increasing in several regions due to the less harsh winters. “EI Salvador alone reported 22,000 cases of dengue fever in 2008, 20 times the number in 2003” (Hilderman, p62).
