Essay Global Warming

“Global warming” has been introduced by the scientific community and the media as the term that encompasses all potential changes in climate that result from higher average global temperatures. Hundreds of scientists from many different countries are working to understand global warming to understand global warming and have come to a consensus on several important aspects. In general, Global warming will produce far more profound climatic changes than simply a rise in global temperature.
An analysis of temperatures records shows that the Earth has warmed an average of 0.5 degrees Celsius over the past 100 years. This is consistent with predictions of global warming due to an enhanced greenhouse effect and increased aerosols. Part of current global warmth is associated with the tropical El Nino, without which a record global temperature would probably not have occurred.
The Earth’s climate is the result of extremely complex interactions among the atmosphere, the oceans, the land masses, and living organisms, which are all warmed daily by the sun’s energy. This heat would radiate back into space if not for atmosphere, which relies on a delicate balance of heat-trapping gases – including water vapour, carbon dioxide, nitrous oxide, and methane – to act as a natural “greenhouse”, keeping in just the right amount of the sun’s energy to support life.
For the past 150 years, though, the atmospheric concentrations of these gases, particularly carbon dioxide, have been rising. As a result, more heat is being trapped than previously, which in...
