Global warming- Myth or reality

Global warming- Myth or reality

Introduction

The temperature of the planet has increased about 0.75 ° C since the industrial revolutionl. Eleven of the years with the highest temperatures in the last 125 years occurred after 1990 and the record is so far in 2005. There is a large consensus on the causes the emission of greenhouse gases, the most common among them being carbon dioxide (CO2) which is produced from the burning of fossil fuels. On the issue of Global Warming Much has been said in recent years, particularly in this 2007; sufficient to recall that the United Nations chose it as the central theme for the commemoration of World Environment this year and it certainly effects are day by day more evident. This time, we analyze some "Myths and Realities" of this phenomenon, attributable to human activities in the last century.

Discussion

Myth or reality

There are certain myths about the global warming such as Data scientists warming overall , are too uncertain to take action. Warming Global and additional CO2 in fact be beneficial, since they reduce the deaths from cold and stimulate crop growth. Entities scientific most respected, have stated unequivocally that warming overall is occurring and is caused by the man from many unfriendlyenvironmenta activities such as burning of fossil fuels and other disastrous activities due to which concerneauthorities have warned that clearly enough evidence to immediately implement measures and contribute to the substantial reduction of such emissions (Houghton, J. T. (1997).

Reality

Global warming is a reality. If current trends are allowed to continue, temperature levels across the globe are likely to reach the highest peak of the last two million years. The year of 2010, followed by 2005 and 1998, was recorded the warmest year since global scientific measurements are carried out (mid-nineteenth century). The same condition was observed for the decade 2001-2010, which saw the highest temperatures of modern times, surpassing the last decade of the twentieth century. The warming has been particularly strong in Africa, parts of Asia and the Arctic, where some regions have seen an increase in temperature between 1.2 and 1.4 degrees from the historical average. In December 2010, the Arctic sea ice has reached the lowest monthly town with an area of ??12 million square kilometers, 1.35 million below the December average for the period 1979-2000. But even more important than this annual record is another fact: since the ...
