Your assignment is to prepare and submit a paper on what needs to happen in order to fix or slow down global warming. As Michael Page (2007) has rightly said,” a firm and ever-growing body of evidence point to a clear picture: the world is warming, this warming is due to human activity increasing levels of greenhouse gases in the atmosphere, and if emissions continue unabated the warming will too, with increasingly serious consequences.”
Global warming is the result of the average increase in the temperature of the earth. It takes place when there is an excessive accumulation of greenhouse gases. The Kyoto Protocol has listed six greenhouse gases that can cause global warming. They are carbon dioxide, nitrous oxide, methane, perfluorocarbons, chlorofluorocarbons, and sulfur hexafluoride. A rise in the temperature of the earth causes many changes. It may lead to changes in rainfall patterns, a rise in sea level. It also impacts humans, animals, and wildlife. Global warming, scientists say, is caused mainly by human activities
At present, the increase in the earth’s temperature is 1/3 of a degree Celsius every ten years. This means we will see an increase of 3 degrees within the next 100 years, which is much faster than the increase that has taken place in the last 10.000 years. It is clear that the speed with which global warming is increasing. soon it will become difficult for human beings as well as ecosystems to adapt. This will be all the more difficult in developing countries.
The earth is surrounded by an atmosphere. Sunlight entering the earth has to pass through the Greenhouse gases present in the atmosphere. On entering the earth the energy of the sunlight is absorbed by the land, water, and biosphere of the earth. The greenhouse gases allow sunlight to enter but stop some of the consequent heat from radiating back to space. It is this trapped heat that keeps the earth warm enough for people to live. This is known as the greenhouse effect. However, if this greenhouse effect increases it can make the Earth warmer than usual and cause the world to heat up more than required.
