Climate Change

Introduction

Climatic change is a serious topic today. Media is focusing on it. Awareness is being created among people so that they can save the world. Climatic change is often referred as global warming. Global warming is causing many drastic changes in the planet earth. Despite the facts, there are a few fiction related to the climatic change too (Bray, 2010).

Methane is released into the atmosphere by livestock, leaks in natural gas pipelines and coalmines, and anaerobic respiration in rice paddies. The atmospheric lifetime of methane is about 12 years. Methane is essentially removed from the atmosphere by chemical reactions. The largest factor in the release of nitrous oxide into the atmosphere is agricultural nitrogen-fertilizer. Other factors include industrial processes and livestock feed lots.

The most important halocarbon to contribute to global warming is chlorofluorocarbons (CFCs). CFC is not produced naturally. They are used in aerosol sprays, refrigeration and air conditioning units, and some artificial foam. Historically, industrial nations have been responsible for releasing the most CFCs into the atmosphere. Currently, the levels have decreased with the amendments made by the Montreal Protocol on Substances that Deplete the Ozone Layer to phase out the production of these chemicals. It is important to note, however, that the chemicals used to replace CFCs are still, to a lesser degree, ozone depletes (Browne, 1998).

The changes in climate hold a significant position in the geologic climate history of Earth. Because of the complete projects of ice drilling in Antarctica, the record of universal temperature and atmospheric composition is broken since 820,000 years. The data, which was recorded, showed 8 major global climatic cycles of 100,000 year long (Browne, 1998).

The majority of articles in the mainstream media indicate that climate change is real and that humans are to blame for the rising average temperature of ...
