Global Warming is is an important issue with many negative effects on the environment. It is caused by both natural and man made causes. Factories ,cars and electricity are some man made causes. Melting arctic permafrost and forest fires are some natural causes. Sea levels are rising causing problems for humans and animals. Storms are becoming more intense and droughts more severe. Global Warming is affecting many animals food supplies and habitats such as the polar Bear. Coral Reefs are being Bleached and dying as well . All of theses negative effects are caused by heat trapping gasses in the atmosphere, such as carbon dioxide and methane gas.
Global Warming is an important issue with many negative effects on the environment. Global Warming is the gradual increase of the earths surface temperature over time. The process is caused by both manmade and natural gases that trap heat in the atmosphere.
Rising sea levels are closely linked with global warming. The sea level has risen four to eight inches only over the last half of a century . Recent studies show that by the year 2100 sea levels will have risen two and a half to six and a half feet . This is being caused by three major reasons thermal expansion, melting of glaciers and polar ice caps, and ice loss from Greenland and Antarctica. Thermal expansion is when the water temperature rises and as result of the increased temperature the water expands. Polar ice caps and glaciers usually partially melt each summer but snowfall in the winter normally would balance out the melting. However the increasing temperature has caused more melting in the summer and less snowfall in the winter. The ice shelves in Antarctica and Greenland have also been melting at an accelerated pace causing them to break away into the ocean. The rising sea levels will eventually have devastating consequences to animal life and people living in coastal regions....
