Climate Change - Essay ExampleThe milankovitch theory implies that all over time three cyclic events vary the amount of solar radiation that reaches the mankind and eventually it causes clime change. According to Burroughs (2007) eccentricity is a cyclical variation that determines the shape of the earths orbit around the sunbathe. The more than elliptical the earths orbit is, the greater the the greater the variation in solar capacity that is received at the top of the atmosphere between the earths perihelion and aphelion. As the earth rotates on its axis, it wobbles hence changing the timing of the solst crackpots, and equinoxes a process known as the procession of the equinox. Volcanic eruptions evict large amounts of sulphur dioxide gas which reacts water vapor found in the stratosphere to form a wooden-headed layer that reduces atmospheric transmission of suns incoming radiation. Sun spots, which are caused by the suns magnetic field are dark, planet sized regions that a ppear on the suns surface. These regions are colder than with an average temperature of 4,000K. Climate change can be explained by these factors although they are only slightly of those which cause climate change.Since 1979, the summer polar ice caps size has shrunk more than 20% and this has not only affected the natives but the globe as a whole. The contraction of the arctic ice cap accelerates global warming since the protective, cooling layer over the arctic is melting and hence the earth absorbs more sunlight (Kininmonth 2004). If the arctic is warmer, this will affect weather patterns since the rest of the universe will alike warm up and eventually food production will decrease. In contrast, most of the world depends on melted glaciers for fresh water supply through lakes and rivers hence their melting will cause of a sudden supply of the same. It will also cause shortage of electricity since a great percentage of the worlds population depends on melting glaciers for hydro electric power. Animals, birds and fish will lose their
