The paper 'Present Global Warming Picture in relation to the Current Changing Climatic Trends" is a good example of environmental studies coursework.   This report gives an overview of the present global warming picture in  relation to the current changing climatic trends. Specifically, it addresses the  interrelationship of the greenhouse effect and global warming. It also discusses facts and myths relevant to the arguments supporting the claims. Is Global Warming a Fact or just a Myth? Global warming refers to the progressive gradual rise of the mean temperatures of the earth’ s surface air and oceans since the 20th century and its continued projection.

It is thought to be caused by the greenhouse effect which is also responsible for the changes in the global climate patterns. Global temperature of the earth surface increased between the beginning and the end of the 20th century. Most of the temperature increases were as a result of increasing greenhouse gases concentration due to human activities such as industrial activities and transportation. Increasing global warming leads to the rising levels of the sea and changes in the amount and rain patterns. Other predictable effects include changes in the intensity and frequency of extreme weather activities, species extinctions and changes in the level of agricultural productions.

Warming, however, differs from one region to another around the globe, though there is no certainty in the nature of these variations. An increase in the global mean surface temperature occurs from the enhancement of the greenhouse effect, mainly as a result of air pollution. The 2007 United Nations Panel on Climate Change predicted that by 2100 global mean temperatures would go up depending on a wide range of scenarios for greenhouses gas emissions (Wishart, 2009). Many scientists, on the other hand, have argued that such a rise in the mean temperature would lead to mountain glaciers and polar ice to melt rapidly hence raising the levels of the coastal waters.

They, therefore, predict that this would cause new patterns and severe droughts and rainfall, seriously affecting food production in most regions. Other scientists, however, maintain that such predictions are exaggerated. The 1992 Earth summit and 1997 Kyoto Protocol to the United Nations Framework Convention on Climate Change tried to bring out the issue on global warming, but it was unfortunate that in both cases the efforts were hindered by the conflicting national economic agendas and disputes between developed and developing nations over the cost as well as the consequences of reducing the emissions of the greenhouse gases (Harmon, 2008). It is a fact and not a theory that global warming is a measurable process that is already in place.

Changes in temperature levels, rainfall patterns alterations and increased storms frequency are occurring and are being measured all over the world.

The Earth has transformed through many phases of warming and cooling over billions of years of its history due to the  effects of the greenhouse. Many natural factors have contributed to these scenarios, with most of them occurring slowly over many periods of time. Temperature levels are increasing so fast on a global scale that is unexplainable due to these natural processes. It is, therefore, a fact and not just a small localized environmental-related problem. In fact, it may be the largest challenge that human beings may be facing in the twenty-first century.

It is now evident in many parts of the world that there is an alarming disappearance of glaciers. An available example is available on the scientific data indicating that Greenland‘ s huge ice sheet is shrinking at an alarming rate. The world lost about 890 cubic miles of ice between 1961 and 1997 (Harmon, 2008). Many scientists agree that the increasing average air temperatures are the most vital factor behind the departure of glaciers on the global scale over such a long period of time.
