Global Warming - Essay ExampleIn 1896 a Swedish scientist put forth the position that burning of fossil fuels causes accumulation of Carbon Dioxide in the atmosphere, which in turn creates a greenhouse effect and elevation of orbiculate temperatures. In the 1950s, the notion of global warming cropped up again when G.S. Callender highlighted the dangers of the greenhouse effect (Weart 2003). Weather models developed in the 1960s guide to the discovery that the levels of certain gases were rising, degrading the fragile ozone layer in the atmosphere. The summer of 1988 was the hottest one on track record with temperatures rising ever since and concerns about global warming prepare escalated since that time. Weather is truly international, but during the rather part of the 1900s weather had low priority. Meteorologists and scientists of various countries banded together under the umbrella of the IGY (International Geophysical Year). drilling of the ice caps commenced in Greenland, yielding the discovery that ice cores held a record of climactic history. This later lead to the formation of the GARP (Global Atmospheric research program) which was headed by the Swedish meteorologist Bert Bolin, devoted to weather forecasting and the study of the steady rising curve of atmospheric Carbon dioxide. Weart (2003) provides a detailed discussion of the phenomenon of climactic changes and the conflicting predictions of scientists on global warming and cooling. He details the IPCC reports of 1995 and 1997, wherein scientific experts predicted that by the middle of the 21st century, the temperature of the world would have increased between 1.5 to 4.50C, figures which have been recently revised upwards to as much as 5.50C.(Weart 2003).
