The Effects Of Climate Change On The Natural Environment

Introduction Of all the changes swirling around us, perhaps those that affect the natural environment hold the most serious implications for the future of human life. Scientist are increasingly convinced that we face global warming. They warn us that the polar ice caps may melt and inundate the world’s shorelines, the climate boundaries may move north about four hundred miles, and many animal and plant species may become extinct (Polyakov, 2010). Climate changes refer to balance of energy coming into the Earth from the Sun due to its subtle shifts in orbit (Whitmarsh, 2009). In contrast, Whitmarsh defines global warming as a continuous rise in the average temperature of the earth’s climate system (2009). Since the 20th Century, the global air and sea surface has increased 0.8 ° Celsius (Polyakov, 2010). According to the research conducted by Polyakov, it has been concluded that two thirds of that increase in temperature have occurred since the year 1980 (2010). Recor ds indicate that each of the last three decades has been progressively warmer. Some scientists indicate that the global warming of the earth has been the actions of mankind since the industrial revolution (Rezai, 2012). In contrast, other scientists state that global warming is part of normal climatic cycles. The climatic cycles occur when the sun’s rays enter the atmosphere, in a harmonious situation, the excess energy leaves the earth’s surface in a form of infrared radiation (Novak, 2006). However, theShow MoreRelatedWhat Role Has Human Activity Played in Causing Climate Change?678 Words   |  3 PagesThe change in global climate is the most powerful problem that currently occurs on the earth. The problems of climate change may be caused by both of human activities and natural events. Climate change is the changes that affect the world’s weather, including shifts in temperature, ocean level, land, and precipitation. The climate change phenomenon can affect everything in the world not only natural environment, but also human society, and the world economy.

Simplistically, climate change is different because climate change is defined as a change in global or regional climate patterns or, in particular, a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels, having been measured over long periods of time, due to the changes in Earth’s orbit and organic carbon which reflect sunlight.

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 socialRead More Essay on Global Warming: The Effects of Climate Change1410 Words   |  6 PagesClimate change is a long-term alteration in the statistical distribution of weather pattern over periods ranging from decades to millions of years. The world is currently experiencing drastic change in temperature. This change can be felt in the tropical climate areas where the weather is getting hotter and hotter every day. The change in global temperatures and precipitation over time is due to natural variability or to human activity. It is also caused by accumulation of greenhouse effects (ArrheniusRead MoreClimate Change And Its Effects On Our Society1545 Words   |  7 Pagessurrounding the topic of climate change. It has become a proven fact that our global ecological and weather patterns are changing in ways that occur at a much more rapid pace than natural cycles typically allow. According to a 2016 Monmouth University Poll, most Americans acknowledge, at least to some extent, that â€Å"the world’s climate is undergoing a change that is causing more extreme weather patterns and the rise of sea levels.† Since humans rely so heavily on their environment to provide a plethoraRead MoreThe Effects Of Fossil Fuels On The Environment1734 Words   |  7 Pagesmetaphorically represents the place in ones journey that must be continued with no alternative routes or ability to make change. In consort with President Obama, many scientists believe the point of no return could occur if significant efforts aren’t made soon.

Climate is defined as weather conditions existing in a particular area over a period of time. When changes in weather patterns start to occur, this is called climate change. Peter Singer describes carbon emissions would extinguish human life. Climate change is a disastrous event because there is a wide range of environmental impacts affecting life expectancy. In different geographical areas, climates will change if temperatures influence them to fluctuateRead MoreClimate Change: Whos to Blame?1008 Words   |  5 PagesClimate change is defined as the alteration in patterns in temperature and weather. A new wave of climate change, bringing warmer temperatures and more extreme storms, began to catch the attention of scientists sometime in the late 20th century. It is blamed perhaps on the increased burning of fossil fuels, contributing to the greenhouse gases that harm the environment (â€Å"Climate Change,† CQ). On the contrary, it is something that simply occurs naturally. It occurs over long periods of time and hasRead MoreThe Changing Relationship Between Nature And Society1658 Words   |  7 Pages As Barrack Obama once stated â€Å"All across the world, in every kind of environment and region known to man, increasingly dangerous weather patterns and devastating storms are abruptly putting an end to the long-running debate over whether or not climate change is real.
