GLOBAL WARMING Global warming is one of the most challenging environmental problems today. It comes longer and more intense heat waves. National borders have no meaning for the atmosphere. The damage of the atmosphere makes harmful elements enter and travel around the world. And now‚ people are worried about the global effects of air pollution. Research shows that the earth’s atmosphere is changing in ways that could be destructive to our life. Pollution could be a major cause of this. One of

Approximately every 100‚000 years Earth’s climate warms up temporarily. The Earth is in a warming period since the Ice Age. The warming periods called glacial periods cause the Earth to retrogress back to a cold ice age climate after a couple of years. This leads to the growing debate of today‚ Is global warming caused by humans? Or caused naturally? This is a controversial issue and debate today‚ however‚ global warming is not man-made‚ in fact‚ it is a normal and natural cycle for the Earth and the carbon

Since global warming appeared during the last decade as a serious environmental issue‚ it has been the subject of a lot of debate. Global warming is defined as the warming of the earth by greenhouse gases emitted into the atmosphere. But there are many questions about global warming‚ from its causes to its effects. Many people even question whether or not global warming exists. And if global warming does exist‚ people question why it exists. Well‚ there are two different viewpoints. The believers

Global warming means a gradual increase in the Earth’s average lower atmosphere due to emissions and build up of greenhouse gases . Global warming is when the earth heats up and the temperature rises. It happens when greenhouse gases such as carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane trap heat and light from the sun in the earth’s atmosphere‚ which increases the temperature. Greenhouse gases are released mostly by the burning of fossil fuels for transportation‚ heating‚ electrical

Introduction Nowadays‚ Global warming is an incontrovertible fact‚ which proves that our planet and its climate are in trouble. Well global warming is a term that denotes a slow warming of the earth’s regular temperature. It was also named exclusively man-made effects‚ in particular carbon dioxide. Carbon dioxide has largely increased during the past forty years‚ and scientists concluded that the average earth temperature has increased solely based on man-made activities such

Controversy over Global Warming One of the largest argued topics in our world today is over global warming. People argue that is real‚ and others argue that it is fake. The effects of global warming create a growing danger for the ecosystem we live in by damaging glaciers and weather patterns. Humans contribute to global warming yet non-believers will think otherwise. Global warming is the greatest challenge facing our planet. According to the IPCC (Intergovernmental Panel of Climate Change) most

Global warming refers to the rising average temperature of Earth’s atmosphere and oceans‚ which started to increase in the late 19th century and is projected to keep going up. Since the early 20th century‚ Earth’s average surface temperature has increased by about 0.8 °C (1.4 °F)‚ with about two thirds of the increase occurring since 1980.[2] Warming of the climate system is unequivocal‚ and scientists are more than 90% certain that most of it is caused by increasing concentrations of greenhouse

October 3‚ 2013 Period 8 Senior Science Global Warming Controversy Humans have known about global warming for many years now. But Al Gore did not discover global warming. Neither did Tim Flannery‚ Peter Garrett‚ Greenpeace or Malcolm Turnbull. However they did add their scientific two cents and made everyone more knowledgeable on what this topic is really about‚ and stressed the importance it has on the Earth. Scientific concern about global warming is not new. This is nothing surprising or

eThe phrase global warming refers to the documented historical warming of the Earth’s surface based upon worldwide temperature records that have been maintained by humans since the 1880s.It is the increase in the average temperature of the Earth’s near-surface air and oceans.In the last 100 years‚ this temperature increased by about 0.8 °C (1.4 °F) with about two thirds of the increase occurring over just the last three decades.According to the exponentss of the concept‚the likely effects of a further
