Joseph F. C. DiMento and Pamela Doughman’s introduction to “Making Climate Change Understandable” presents an argument for climate change that denies frequent deliberate intervention with the climate by the human population but rather supports the accidental change in climate. The authors also claim that because climate change is so difficult to understand, people do not recognize it as a grave issue. Early in the text, DiMento and Doughman clearly state the purpose of the article as follows,…

Climate change is the most highly influential topic in 21st century. It is now considered as a global phenomenon, which significantly impacts on human life. From the early beginnings of humans, we had changed the natural rule in many ways: by hunting, gathering, taming the wild animals… At first, the change of nature brought many practical benefits for the development of human beings. Over the years, people has gradually affected this beautiful planet, including its climate. Humans risk…

he Merriam-Webster Dictionary defines a crucible as, “a vessel of a very refractory material used for melting and calcining a substance that requires a high degree of heat.” Other interpretations of the word mean, “a severe test,” and “a place or situation in which concentrated forces interact to cause or influence change or development.” The Crucible by Arthur Miller and today’s society are very much like the inside of a crucible because they have social pressures, private pressures, and…

Global warming and climate change: Threats and impacts Global warming and climate change are “the talk of the town” in this century, with its unhealthy effects already being brought to lime light by its annihilate power of damaging the society by floods in one part of the country and droughts on another. Before embarking impacts of global warming and climate change, we should know what green house effect mean. GREEN HOUSE EFFECT Green House effect is the phenomenon in which the earth's…

warming. Global warming is a phenomenon caused by the hole in the ozone layer. This hole allows ultraviolet, also known as UV, rays to cover the Earth like a blanket since the purpose of the ozone layer is to block these rays. The burning of fossil fuels releases carbon dioxide into the air that wraps the UV rays around the Earth which causes the warming of the Earth. In understanding what global warming is and what causes it, we can better understand how to prevent global warming and preserve…

Introduction Acid rain is a rain that contains a high concentration of pollutants, chiefly sulfur dioxide and nitrogen oxide, released into the atmosphere by the burning of fossil fuels such as coal or oil .It can have harmful effects on plants, aquatic animals and infrastructure, when the sulfur dioxide and nitrogen oxide, react with the water . The chemicals in acid rain can cause paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues.…

Climate Change is the main issue not only one nation but also global impressing and concerning. The global average temperature increased about 0.74 oC during 100 years from 1906 to 2005 and it will be grown 2 oC more in the next 100 years if human activities remain producing greenhouse gases as the same now. (IPCC, 2007). Climate change will bring about prolong drought, frequent and intended flooding, and other natural calamities. Then the impacts from these climatic disasters will be differed…

From the experimental study it is found that the heat transfer rate in notched fins is more than the un-notched fins. The average heat transfer coefficient increases with the heater input. It is clear that for the given heater input, average heat transfer coefficient of notched array is 30 to 40% higher than corresponding un-notched array. The average heat transfer coefficient for notched fin is better than un-notched fins. Also the copper gives more heat transfer rate than aluminum plate…

Global Warming The climate system of Earth responds to changes in external factors that are able to push the climate towards warming or cooling. These factors include changes in atmosphere composition (concentration of greenhouse gases), volcanic eruptions, and solar activity changes. All of these factors combined create current tendency of climate change that is described by the term “global warming”. Global warming is the continuous rise in average temperature of Earth's climate system.…

Fossil Fuels: Pollution whether it is vehicular, electrical or industrial is the main contributor to the global warming. Everyday billions of vehicles release various gases into the atmosphere. This causes earth to warm up and increase its average temperature. Electricity causes pollution in many ways. Over 75% of the electricity worldwide is produced by burning of fossil fuels. Many gases are sent into the air when fossil fuels are burnt of which main is the carbon dioxide gas. Fossil fuel like…
