Global warming Global warming the biggest threat in 21st century Introduction The term global warming has been common in the fields of whether and climate. The term does not posses the literal meaning as such but simply implies change in climate. The change in climate is attributed to overall rise in average temperatures of the universe. This poses a great threat to mankind (Korgen‚ 2007). The dangers attributed to global warming include health issues‚ scarcity of some vital natural resources

Jacqueline Sanchez Brad Stiles Research Paper Global warming is no longer a myth and as consumers of resources‚ the world has to change and conserve their energy usage. There are many things one can do‚ but informing others how to take these dire steps our world needs in order to survive and support humankind. With CO2 making up over 70 percent of our atmosphere‚ we need to focus not only on how to slow down its growth‚ but removal of it s existence from the atmosphere to the right level of

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

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

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

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

come can we not do anything about it or at least try it? We’re all aware of the seriousness of this problem: CO2 emissions and other substances such as Nitrogen oxide‚ Hydrocarbons or Carbon Monoxide‚ are destroying our ozone layer and causing global warming to arise. In consequence‚ the greenhouse effect makes the world’s temperature to reach higher levels and lead to enormous disasters such as North Pole melting‚ Pollution... All right then‚ I know that each one of you here is perfectly aware of
