Global warming

        Global warming is an average increase in the temperature of the atmosphere near the Earth’s surface and in the troposphere, which can contribute to changes in global climate patterns. Global warming can occur from a variety of causes, both natural and human induced.

CAUSES OF GLOBAL WARMING

·         One significant cause is that carbon dioxide is expelled from our automobiles, minivans as well as other vehicles, and if these vehicles give off poor mileage you can be sure that there will be more CO2 being emitted into the atmosphere, which only contributes further to global warming.

·         Another cause is methane, which is next in rank to carbon dioxide as a greenhouse gas. The worst part of methane is that it has the undesirable property of being twenty times more effective in trapping heat in our atmosphere, and another worrying aspect to this is that methane levels have risen by as much as, it is believed, one hundred forty-five times in the last century.

·         Another cause of global warming, nitrous oxide, also for many decades, we have seen massive deforestation that is the second most important cause after carbon emissions, in making the world warmer than it should be.

THERE ARE TWO MAJOR EFFECTS OF GLOBAL WARMING:

·         Increase of temperature on the earth by about 3° to 5° C (5.4° to 9° Fahrenheit) by the year 2100.

·         Rise of sea levels by at least 25 meters (82 feet) by the year 2100.
