The Threat Of Global Warming - 1487 Words

Ever since the twenty-first century, the injury and menace posed by global climate change to human being has long been acknowledged by public. In the face of global warming, a series of resulting problems inflict a serious threat on the nature environment, which is the material base of the human being depending on. Therefore, climate change is no longer just a discipline problem but also has gradually become a major social problem, which has draw a common concern for us humans. During this, the resulting problems coming with the climate change has been transforming from oneness to diversification, from being known to being unknown. Various new phenomena lead to the change to human survival state. Most importantly, disaster in different†¦show more content†¦On the contrary, it is generally agreed by the majority of scientists that human activities, especially since the industrial revolution in 1840s, including the production of factories, the consumption of customers, the usi ng of land among others, makes the most contribution to the global warming. The assessment report published by IPCC (Intergovernmental Panel on Climate Change) in 2007 notes that the likelihood of the human activities to be the causes of the climate change is more than 90 %. The IPPC s reports on climate change highlight how human activities have affected global temperature in the past 50 years. There are the primary human activities that contribute to the climate change. One of many points is burning of fossil fuels results in a tremendous emission of green house gases in the atmosphere. Since the Industrial Revolution in 19th, the demand of fossil fuels increase sharply. Fossil fuels such as oil, coal and natural gas supply most of the energy neediness for transportation, electricity generation and household heating. According to the IPCC’s reports, burning of fuels (world wide) produces around 21.3 billion tons (21.3 gigatons) of carbon dioxide every year. Though part of the carbon dioxide exited in the human life circle would be absorbed naturally, the remainder gets caught up in the atmosphere and contributes to global greenhouse gas warming. Another point is improper usage of land is also one of the most important factors that should draw
