Nowadays, climate change is became a major global issue which are affecting our life such as global warming ,mean sea level changing and more extreme weather events etc .According to the research of Intergovernmental Panel on Climate Change 2007 ,it showed that the global mean temperature rose by 0.74 °C during the hundred year period from 1906 to 2005. Between 1956 and 2005,the rising rate was 0.13°C per decade in this 50 years , nearly twice the rate in the past 100 years. Eight (2010, 2005, 2003, 2007, 2006, 2009, 2012, 2004) of the last ten years (from 2003 to 2012) rank among the 10 warmest years on record. It seems that climate change is potentially affecting our life.In fact,human activities and natural effect are the causes of climate change.Generally,most of the scientists and government agree that human activities is the main causes of climate change rather than natural causes.Therefore,this essay is going to discuss why human activities change the climate more seriously than natural effect.Afterward,I will also present some possible solution to reduce the climate change.
Climate change is one of the biggest concerns for all nations across the globe over centuries. Climate shift refers to changes in patterns of weather which can be indicated through global warming, natural disasters and rise in sea level. There is a group of people, climate change skeptics, argue that climate change is not the result of human activity, meaning that it is naturally occurred. According to Slaght, this refers to internal factors which are the interaction between the atmosphere and ocean, and external factor, such as solar energy variations and volcanic eruption (John Slaght, 2009). However, most scientist claims that human also involve in this process. Consequently, this essay aims to discuss the impacts of greenhouse gases on climate, and then the contribution of human to climate change and lastly, some statistics about the effects of global warming.
Climate Change can result from both natural events and human activities. Some examples of natural causes of climate change are volcanic eruptions, ocean currents, solar variations, and earth’s orbital changes. Some examples of human activities are fossil fuels, warming of temperature due to industrialization, and deforestation of tropical rainforests. Factors of climate change can change and vary naturally over time. The issue of the fast increase in earth’s temperature over the past years is one of global importance and disputed origin. All these justifications are for the change in the earth’s temperature are valid, however, there is a reason to believe that human activity and carbon dioxide emissions are a great part of the cause for the
Drawing from the research of organizations such as the IPCC and scientists skilled in multiple disciplines, I will explore the history, perceived causes and impacts of climate change. Based on this examination, I will propose my own solutions, at the local and global levels, to mitigate or adapt to probable impacts from global warming.
“Climate change is no longer some far off problem; it is happening here; it is happening now” (Obama). President Barack Obama states a good fact; climate change is affecting the world tremendously. Glaciers are melting at an astonishing rate and the surface temperature of the world is only increasing. Currently, scientists argue that climate change intensified due to human activity, however, the circumstance is quite the opposite. Although, human activity plays a part in global warming, it does not affect the major scale of climate change. For instance, the human generated greenhouse gas emissions are too small to substantially change the earth’s climate. In addition, the warming and cooling pattern occurring over the 20th century results from the fluctuations of the sun’s heat and ocean currents. Finally, the computer generated prediction climate models are faulty and use misleading science. Evidently, there are many misconceptions of the impact on climate change, which many blame human activity for the intensified climate change. Human activity is not responsible for global climate change because fluctuations of the sun’s heat and ocean currents hold responsibility for the increased surface temperature, the levels of CO2 do not correlate with human activity and the computerized climate models display inadequate and incorrect information.
Global Warming is a universal concern that has gained worldwide attention. As members of Congress, we have heard and learned new and different facts about the process of Earth. Some causes and effects of global warming are easy to understand, with substantial evidence, yet there are still unanswered questions and reasoning as to why global warming is occurring. This essay is to outline the background of global warming and to display opposing viewpoints. Since there is not enough evidential research to connect global warming with natural factors, human activity, and its impacts, we might take advantage of its beneficial gain to our environment, economic, and social system. The facts and fictions of global warming will convince members of Congress that there are opposing viewpoints to global warming and its effects.
The effects climate change commonly referred to global warming are usually far reaching and the effects have since led to enormous social and ecological changes. The global warming have been initiated directly or and indirectly by human activities that usually lead to greenhouse gases emission into the environment. Some Scientists believe that climatic changes are driven by human activities (Haldar, 2011). Numerous evidences t climate change have been cited including rising in sea levels, increasing of snow cover especially in the Northern Hemisphere, and instrumental temperatures among other. Nonetheless, numerous ways causes and effects usually lead to these climate change evidences and the causes and effects of global warming are discussed in this essay.
Over 35 years ago, climatologist Wally Broecker coined the term global warming in a paper outlining the trends that he was noticing with temperature and C02 levels (Stefan). Ever since then, the debate has heated up on the controversy of global warming. Politicians have even used the issue to boost their campaigns. Some question whether the earth’s temperature is rising at an unusual rate. Scientists perform experiments from glacial ice to observe the correlation between carbon dioxide levels and temperature. Scientists have changed the debate over the years from debating whether global warming was actually happening to the current debate about what is causing global warming. Therefore, the term global warming in this paper refers to those who believe humankind is the main cause for the current heating trend. The debate falls between two main arguments: Global warming is being caused by man-made C02 emissions and global warming has no correlation with the amount of man-made C02 emissions released into the atmosphere.

‘Global warming’, also referred to as ‘climate change’ or the ‘anthropogenic greenhouse effect’, is defined as ‘the discernible increase in mean global temperature resulting from the release of greenhouse gases produced by human activities’ (McCright & Dunlap, 2000, p. 499). The IPCC (Intergovernmental Panel on Climate Change) defines global warming as ‘any change in climate over time, whether due to natural variability or as a result of human activity’ (IPCC, 2007, p. 30). The mainstream climate scientists around the world have come to a consensus conclusion that the global warming is happening, posing a severe threat to the world, and is largely caused by human activities releasing greenhouse gases (GHGs) through burning of fossil fuels and deforesting the land (Wang & Oppenheimer, 2005). However, unfortunately, much of the world’s population is unconscious regarding this scientific agreement due to the coordinated efforts produced by certain industries that spread propaganda regarding global warming. This essay tries to offer a comprehensive discussion regarding the general myths and misunderstandings about the global warming and takes a stance for global warming as a reality.
