Global Warming - Essay Example Many of the living creatures cannot bear this change and the result is open in the form of dead. According to the scientists, main causes of the global warming are the greenhouse gases those are produced by deforestation and burning the fossil fuel. History of global warming Scientific research on global warming itself was the result of many influences, and the interesting thing is that these influences include misconceptions to government pressure and findings. In 1896 a scientist from Sweden presented a new idea the burned fossil fuels such as coal, which is the reason to increase the carbon dioxide gas on atmosphere. And the increase in the level of Carbon dioxide increases the average temperature on the earth. In the 1930s, people of United States and North Atlantic region realized that these regions have much warmed during the previous half century. At that time many of the scientists argued that the change in the climate is just a phase of some moderate natural cycle. The cause of this change was not described by anyone at that time and referred that condition to â€Å"unknown causes†. At that time one unique argument was made by Guy Stewart Callendar who was an engineer. He insisted that the greenhouses are the main cause of global warming. At the start of 1950s, few scientists worked on the Guy Stewart Callendar’s claims with the help of new improved methods and calculations. After that some new studies in 1961 also proved that the level of carbon dioxide is rising day by day. Over the next few decades scientists used simple models and specific calculation to measure the climate change. At that time General predictions with the help of calculations and computer models made. In 1967 more calculations by scientists suggested that the rise in the level of temperature might be little degree in next century so there is no need for any policy for this purpose. But at that time some scientists forced for official attention and government funds fo r more research purposes. In the early 1970s, it was noted that there is a rise in the climatic changes. This term referred to â€Å"environmentalism†. The rise in environmentalism raised public doubts about the global warming. At that time some scientists raised the point that human activities was the main reason for increasing the smoke and dust elements into the atmosphere and these elements block sunlight. Factors that brings rise to global warming At earlier times scientists had used a certain methods and calculations to measure the change in climate, but in 1970s they were using many techniques about the factors that can cause influences in the change of climate. Improved computer models with improved calculations were used to measure the jumps in climate level. With the help of these models scientists take information that how these jumps could happen. Researchers had to know that the one other factor that can causes the global warming was unexpected discovery, the res ult of this discovery stated that the level of gases was rising, which would add seriously to global warming. At the end of 1970s global temperature has evidently began to rise. The scientist those were researching on that began to warn the world that these changes could be dangerous if proper security measures are not taken. At the main time Corporations and individuals who opposed these thoughts spent large amounts to convince people that there was no problem at all. After these issues the world governments decided to create an
