Human causing global warming
Many of the human activities are responsible for the vast changes in Earths climate. The human activities that are increasingly affecting the nature is the increased concentration of green house gases in the atmosphere, airborne particles, alterations of land, increasing air pollution, etc. The emission of green house gases such as chlorofluorocarbons; carbon dioxide, nitrous oxide, methane, etc. are causing drastic changes in the pattern of nature and many other naturally occurring activities. Carbon dioxide concentration is increased in atmosphere due to changes in land use and burning of fossil fuel. Carbon dioxide has increased more than 80% since 1900. Research shows that this increased level of carbon dioxide will be present in the atmosphere for thousands of years. It is certain that this increasing level of green houses gases will cause the Earths surface to get more and more warm.
It is difficult to predict certain climatic changes which are induced by human activities. Difficult to say as what will be the speed of occurrence, exactly what amount of change will take place in the climate, what will be the location of change as no scientists can predict the level of human activities taking place? Scientist is sure of other predictions about what these human activities result to. They are confident about their prediction such as melting of ice in polar regions, the mid continents will be much more warm as compared to oceans, the sea level will rise, change in pattern of hydrologic cycle which will result in lowering or raising of water supply that might result either in draught condition or flood, etc.
The level of global warming in future will vary to great extent as there will be changes in economy, population, rate of emission of green house gasses, etc. Even if measures are taken to decreases the emission of certain pollutants, the effect of the green house gasses already present in the atmosphere will not decrease or reduce as they are present in atmosphere in concentrated form. To prevent the dangerous effects of global warming it is most important to stabilize the concentration of green house gasses in the atmosphere.
Humans preventing global warming.
Global warming has already started with its impacts on Earth and the increasing level of green house gasses in the atmosphere will lead to increasing impacts. It is necessary that humans considrable make efforts to prevent global warming at this critical stage. Humans can take efforts to get the information as to how every single human can contribute to protect the nature. The effects of global warming can be brought to most of the humans by way of education or seminars or lectures which might help humans to understand as how their activities are affecting nature and finally the result is global warming.
Please help us spread the word about Global warming, email this link to your friends or put it on your website to educate them about what is Global warming.
