What is Global Warming, History of Global Warming

Global Warming also known as the dark side of our unchecked industrial process can simply be defined as the increase in the temperature of the earth’s atmosphere, landmasses, and oceans. According to scientists the earth’s temperature is changing at rates faster than the normal rate due to the increase in the levels of the greenhouse gases in the atmosphere. For example carbon dioxide aids in blocking the heat in the atmosphere which leads to the temperature rising gradually. If the emission of carbon dioxide remains unchecked the glaciers would melt leading to severe flooding. The Intergovernmental Panel on Climate Change has stated that the rise in temperature over the last couple of decades has been due to the large concentrations of greenhouse gases due to activities such as burning of fossil fuels, deforestation, burning of oil, etc.

History of Global Warming
Over the past 100 years the level of carbon dioxide in the earth’s atmosphere has risen intensely. Once again the main cause of this has been the burning of large quantity of fossil fuels, coal, petroleum, etc. The global temperature has also risen by almost 0.6 degrees Celsius within the last century. Scientists believe that half of this rise in temperature was caused by humans alone and that if the human race does not act now the earth’s temperature will continue to increase by 1.4 to 5.8 degrees Celsius or in other words 2.5 to 10.4 degrees Fahrenheit over the next century. This increase in temperature does not seem to be of much significance. However, it must be noted that during the last ice age the earth’s temperature was only 2.2 degrees Celsius cooler than it is today.

Changes in Climate
The magnitude of this increase in the earth’s temperature can be very overwhelming. Scientists believe that the polar regions of the northern hemisphere in specific will heat up more than other parts of the planets therefore leading to the melting of glaciers. Global warming will also lead to the sea levels rising causing cities on islands or along the coasts to submerge in water. Some other major concerns are that most likely majority of the plant and animal life will become extinct, agriculture will no longer be the same, and last but not the least there will be an increase in hurricanes and droughts. Basically global warming will lead to a shift in climate change such as, the areas that have snowfall will no longer have snow and the areas with no snow in the winters will begin to experience snowfall.

Use of Green Energy
Green energy or the use of alternative energy can help us revive the beauty of our planet. Green energy is the use of those energy sources which do not generate any harmful chemicals and gases which are dangerous for our survival. The alternative energy sources like solar energy, wind power, tidal power and geothermal heat can liberate us from the concern for climate change at large. We need to focus more and more on the industrial activities which are environment friendly. In order to save our planet we must fight global warming by growing more trees. The activities which require use of oil, gas and coal should be controlled and the treatment centers for the waste decomposition should be established .As end consumers we must cut down the use of industrial products which are not based on the principle of green technologies. More over we should try to take electricity connection from only those companies which are producing electricity in a way which is possibly the least damaging to our planet. It is now that we realize the need for cleaning our planet and making it worth living for our next generation.
