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

WORLD Global Warming The Hottest Debate of the Decade Kristen Flint ‘14 G lobal warming has been a point of contention in our society for years‚ and the extreme views from both sides of the argument have transformed the subject of global warming from a factual theory into a mythical idea. At one extreme‚ those who consider themselves “green” bemoan the tragedy that man is causing our planet’s climate to heat up while the other side of the debate refuses to believe any part of the global warming

Global warming is the increase in average temperature of the Earth’s atmosphere and oceans over time. Most of the warming observed over the last 50 years is attributable to human activities‚ especially the emission of greenhouse gases such as carbon dioxide gas. In recent years‚ extreme heat waves caused more than 20000 deaths in Europe. Also‚ melting icebergs and rising sea levels are observed. Global warming is a crucial problem in the world‚ it may lead to disastrous consequences such as extinction

Global Warming Today‚ global warming poses the greatest threat to humanity and our planet earth. Global warming is actually not a new phenomenon by any means. In fact‚ it started alongside with the industrial revolution centuries ago. Nonetheless‚ global warming has taken an ugly turn due to rapid ongoing buildup of human-related greenhouse gases. For example‚ CO2 emissions reached 8.5 billion tons in 2008 and the average temperatures of the earth has risen by as mush as 0.2 degree Celsius

Global warming is caused primarily by carbon dioxide from burning coal‚ oil and gas. Certain gases that trap heat are building up in Earth’s atmosphere. The primary culprit is carbon dioxide‚ released from burning coal‚ oil and natural gas in power plants‚ cars‚ factories‚ etc. (and to a lesser extent when forests are cleared). The second is methane‚ released from rice paddies‚ both ends of cows‚ rotting garbage in landfills‚ mining operations‚ and gas pipelines. Third are chlorofluorocarbons (CFCs)

Global Warming Many researchers‚ scientists‚ and environmentalists are expressing concerns about changes in the overall climate of the earth. Some believe that a dramatically dangerous warming is taking place in the overall global climate‚ a problem that is referred to as "global warming". According to Benson (2012)‚ Global Warming is a term used to refer to an increase in Earth’s average surface temperature. It is due mostly to the release of greenhouse gases (GHGs) into the

I. WHAT IS GLOBAL WARMING? Global warming is the gradual increase of the Earth’s average measured temperature overtime. This measured average temperature is derived from both the near-surface air as well as ocean waters. Scientists began measuring this temperature beginning in the mid-20th century and have continued to monitor fluctuations and deviations in measurements ever since. The average global temperature increased approximately 1.33°F over the past 100 years ending in 2005. This led the

Global Warming is a major problem which our environment faces today terribly. This global warming is caused due to Greenhouse Effect. What is greenhouse effect? It is a condition in which Earth’s heat trapping increases more from the normal levels. There are many causes of Global Warming. The destruction and burning down of tropical forests ‚ traffic clogging up the city streets ‚ rapid growth of unplanned industries etc cause GLOBAL WARMING. The effects of Global Warming is very dangerous for

Global Warming Global warming is a huge environmental and economic challenge that we are facing in the 21st century. Global warming is also commonly referred to as the greenhouse effect. Global warming can affect entire ecosystems and climates‚ which in turn affect the way in which people live. We in our lifetimes will not be around to see the major outcome of global warming; however‚ it is still a major concern. It has come to be known that the major increase in temperature over the last century

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
