National Science Foundation and global warming Essay

National Science Foundation and global warming - Essay Example Hence the outcome presented by researchers mentioned by Longley (2006a) indicates that the resulting transfer of heat into the oceans would cause global sea levels to rise another 4 inches from thermal expansion. (Longley, 2006a) In the present scenario where global warming is the outcome of extensive fossil fuel emissions, it would be no use to look upon the main causes of global warming. However, still the onus is on the shoulder of human activities that cause global warming. Central consumption patterns have generated such a rapid worldwide deforestation that a majority of the earth's rainforests have gone early in the 21st century. However, the outcome is in the form of uncultivable land as global warming has made 53 percent of the world's land uncultivable, and desertification had encompassed nearly two-fifths of the earth's surface by the end of the 20th century. Oil slicks on the oceans and the rise in sea level triggered by global warming have endangered more than half the world's coastal ecosystems. According to a UN Report, yet 60 percent of the world's population lives within 65 miles of coasts, relying on those habitats for food and economic livelihood. Among many Governmental efforts to reduce global warming is the committee set up by National Research Council (NRC), which analyzed not only the global warming trend and ratio but also evaluated the extent to which warming in many versatile ways may be hazardous to humans. The committee being consisted of eleven top most researchers and noble prize winners of the U.S after examining concluded that nothing can be done to stop the dilemmatic conditions rising from global warming because of the reason that 21st century human activities are unlike the past centuries when man was not dependant on machines. Global warming, according to Adler is not a serious threat as predictions for future warming are largely based on computer models that are unable to predict even current temperatures accurately. So, how come the world can rely upon such models that predict dangers of greenhouse in the future Since 1979, the so-called highly accurate satellite measurements taken have remained unsuccessful in finding warming trend. And independent measurements from weather balloons corroborate these readings. So, usually measurement near cities show high temperatures in the global climate. (Adler, 1998) Today humans are based upon technical operated machines and computer models, due to which it would be a mistake to continue thinking of processes to reduce global warming. Global warming would continue to rise as long as there is a continuous greenhouse gas emission. (1) Political leaders have always warned of global warming, as the people they led have never bothered about to increase their emissions of greenhouse gases. One very large problem in greenhouse effect refers to the climate
