Global Warming As we know‚ global warming is becoming a global issue. It alarms the whole world to protect the destroyed environment. Global warming is a "natural phenomenon". In general‚ we know that the origin of global warming is the emission of carbon dioxide. It was verified that the relationship between carbon dioxide and temperature: when there is more carbon dioxide the temperature gets warmer. This topic should be discussed under current situation to advocate people concerning with this

Many people wonder if global warming is happening at all and if it is happening‚ can it really hurt us. Many scientist claim that the human race is to blame for global warming‚ while others claim that the human race

Global Warming: Who’s to Blame? It seems that a single week does not go by without hearing something about global warming. It has been all over the news for as long as I can remember. Because of this media bombardment‚ I would be surprised to find a single person in America that does not know about global warming. I’ll also go so far as to assume that the vast majority of the people you ask will tell you that not only is global warming occurring‚ but humans are to blame. In fact

What is the main cause of global warming? In the last century‚ the sea level has rose for about 17 centimetres. The rate in the last decade is however‚ nearly the double of last century. Major global surface reconstructions also showed that the Earth has warmed since 1880 and it’s still going on. Oceans are also warming up‚ due to the heat. Not only that‚ the Greenland and Antarctic ice sheets are melting‚ glaciers are disappearing and extreme weather events have occurred more often. All these

Global warming W hat is global warming? The changes in the surface air temperature‚ referred to as the global temperature‚ brought about by the enhanced greenhouse effect‚ which is induced by emissions of greenhouse gases into the air. How Global Warming Works Carbon Dioxide (CO2) Fossil fuels (coal‚ oil‚ natural gas) Example of the Greenhouse Effect The Sun’s energy passes through the car’s windshield. This energy (heat) is trapped inside the car and cannot pass back through the windshield

challenges earth is facing is Global Warming. The global warming hypothesis orginated in 1896 when Svante Arrhenius‚ a Swedish chemist‚ developed the theory that carbon dioxide emissions from the burning of fossil fuels would cause global temperatures to rise by trapping excess heat in the earth’s atmosphere. The term “Global Warming” signifies the temperature of the earth’s neon- surface air. The change in climatic conditions is one of the impacts of global warming. It is directly impacting on rising

GLOBAL WARMING AND THE EFFECTS ON EARTH One of the hottest topics being discussed now a days is the effects of global warming on the environment and the efforts being made in order to combat the potential effects. Simply put‚ global warming refers to the environmental effects caused by the constant emission of carbon dioxide from carbon based fuels. These effects are supposedly widespread; the temperature of the earth will rise‚ the land becomes less conducive to‚ vegetation‚ and various

Global Warming “The Earth ’s climate has changed throughout history. Just in the last 650‚000 years there have been seven cycles of glacial advance and retreat‚ with the abrupt end of the last ice age about 7‚000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.” (NASA.GOV) Going through the history in our planet’s
