Earth is staring into the jaws of a major catastrophe, and even its famed natural survival systems will not be of much defense against the blow it is about to take. The weakening immune system of the earth can be traced directly back to global warming which is a slow, albeit, destructive process. The very real threat that global warming poses can wipe out every single trace of human life on earth in due course, make no mistake about it, if something isnt done to arrest it where it stands.
The Phenomenon of Global Warming
The presence of gases like carbon dioxide, methane, nitrous oxide and water vapor is essential for sustenance of life on earth. These gases keep the temperature of the atmosphere warm to such an extent that life can flourish on earth. These gases absorb the infra-red radiations from the sun. While some rays are bounced back from the surface of the earth, some rays are trapped in forms of heat by these heat-trapping or greenhouse gases. The atmosphere of the earth is enveloped by a thin layer of ozone that prevents excessive amounts of infra-red rays from entering the earths atmosphere.
The Science of Rising Temperatures
With technological advancements and the increasing use of fossil fuels as sources of energy, the levels of carbon dioxide and other greenhouse gases has been increasing in the troposphere. This means that a lot more heat is trapped in the atmosphere. There are certain particulates, like carbon monoxide, that tend to react with ozone. Ozone is unstable in nature and tends to react very fast. Gases like carbon monoxide and nitrous oxide react with the ozone layer as soon as they come in contact with it. A lot of heat is released in the reaction, which causes holes in the ozone layer. These holes allow the intensified and concentrated infra-red rays to hit the earths atmosphere, causing a further increase in temperatures.
Effects of Global Warming
The climatic change that the world is witnessing today also results in the disappearing of ice slabs on the Arctic Circle and Antarctica. Glaciers are melting at a steady pace which exposes various landscapes to the risk of being completely submerged in water in the near future. The food chain has been terribly disturbed as a result of varying temperatures around the world, and the natural habitats of various species of animals have been destroyed. Deforestation and dry periods accompanied by rising sea levels are bound to pose problems for land and sea animals. Recent statistics have revealed a shift in the hibernating and migratory habits of animals, and this change (early arrival of spring, warmer winters and early arrival of summers) has left these animals stranded in the middle of nowhere with no food and no shelter.
Geologists suggest that global warming would also result in severe natural catastrophes like earthquakes, volcanic eruptions, cyclones and hurricanes in the near future. Mild earthquakes and volcanic eruptions have become a regular occurrence in certain areas of the Arctic Circle. As the ice melts away into the oceans, the pressure on the earths crust is released and the tectonic plates are free to move against each other. There is a greater need than ever to assess and implement global warming information to help ensure the continued existence of planet earth, and her many species of life.
