Thesis: Global warming is a human induced phenomenon causing a dramatic rise in average global temperatures and posing a major threat to our planet and it’s ecosystems. Points of Evidence: The science is clear: Human activity is causing our climate to change. -When we extract and burn fossil fuels such as coal or petroleum‚ we cause the release of carbon dioxide (CO2) and other heat-trapping “greenhouse gasses” into the atmosphere. Though natural amounts of CO2 have varied from 180 to 300

Abstract Global warming is a direct result of human activities on this planet. Our species have inhabited this planet for thousands of years but only since the 1900’s have scientists been able to measure the changes that we have induced on earth. It is estimated that temperatures have risen globally by about 0.9 degrees Fahrenheit‚ which may seem minor‚ but have caused physical changes on the planet (and potentially dangerous ones in the future). The “greenhouse effect” is a term many politicians

Global Warming is caused by human pollution; Nowadays our environment becomes different from the past‚ now the world is becoming dangerously warmer due to the human pollution of greenhouse gasses‚ such as carbon dioxide‚ methane‚ nitrous oxide‚ and deforestation‚ which it traps heat that would otherwise escape from Earth. “These are the Top 10 Global Warming Effects and Causes: (1) Carbon dioxide emissions from fossil fuel burning power plants; our over increasing addiction to electricity from coal

Abstract This report studies secondary research to discover the effects of global warming and the consequences it has on sea levels‚ ice melting and the polar bear. Websites researched were NASA‚ ICUN‚ National Geographic‚ BBC News‚ The Independent‚ IPCC‚ Arctic Council‚ National Resources Defense Council‚ UN News and D.V.D. called ‘An Inconvenient‚’ truth. Evidence researched supports the conclusion that scientists believe global temperatures have been rising and that human activity is a significant

CAUSES OF GLOBAL WARMING: Global warming also causes sea surface temperatures to rise‚ precipitation patterns to change‚ etc.. (NASA‚ 2002) Global warming can have many different causes‚ but it is most commonly associated with human interference‚ specifically the release of excessive amounts of greenhouse gases. (EPA‚ 2006) Global warming is caused by excessive quantities of greenhouse gases emitted into Earth’s near-surface atmosphere. Greenhouse gases are both man-made and occur naturally

challenges that global warming presents to both governments and business Introduction (250 word approx.) This essay discusses the challenges that global warming presents to both the government and also how they affect businesses. Many people think global warming is just the weather becoming warmer‚ but in fact this is not the case. Global warming makes the weather more unpredictable as some places become colder‚ some hotter‚ some more drier‚ some more wetter and so on. Global warming is defined as

Introduction A Global Warning: Global Warming | The world is warming dangerously. It depends either on the natural causes or the artificial causes like human based greenhouse gases. This affects both the vegetation and zoological environment and also the human | life. Its effects are gradually increasing every year.The purposes of our project are:·To investigate the causes and the effects of global warming and to present the results of our survey.·To attract attention on the solution proposals about

GLOBAL WARMING Probably the most worrying threat to our planet at the present time is global warming. The main factors resulting in the warming of the earth is the emission of CO2. CO2 damages the ozone layer and comes from several sources. The most problematic comes from the burning of fossil fuels from electric power stations. This releases thousands of tones of CO2 into the atmosphere every year. Another cause is the burning of gasoline for transportation. It continues to increase because

Title: Global Warming Specific Purpose: To inform the audience about three issues of how global warming is affecting our weather‚ animals‚ and our future. Thesis: According to National Geographic Average temperatures have climbed 1.4 degrees Fahrenheit around the world since 1880 and by 2050‚ rising temperatures could send more than a million of Earth’s land-dwelling plants and animals down the road to extinction. Introduction I. Open with Impact: Is the climate warming? The impacts of global

Global dimming‚ a gradual reduction in the amount of global direct irradiance at the Earth’s surface‚ has partially counteracted global warming from 1960 to the present.[55] The main cause of this dimming is aerosols produced by volcanoes and pollutants. These aerosols exert a cooling effect by increasing the reflection of incoming sunlight. The effects of the products of fossil fuel combustion—CO2 and aerosols—have largely offset one another in recent decades‚ so that net warming has been due to
