Global Warming












I heard About Global warming so many times but I used to ignore it.One time my proffesor in Philosopy of man decided to handle a film showing on class about the documentary entitled "The Inconvinient Truth".At first, I fell so bored and sleepy watching that documentary plus where in a dark room.But I get interested with the topic,about our mother earth.
WHAT IS GLOBAL WARMING?

Carbon dioxide and other gases warm the surface of the planet naturally by trapping solar heat in the atmosphere. This is a good thing because it keeps our planet habitable. However, by burning fossil fuels such as coal, gas and oil and clearing forests we have dramatically increased the amount of carbon dioxide in the Earth’s atmosphere and temperatures are rising.
The vast majority of scientists agree that global warming is real, it’s already happening and that it is the result of our activities and not a natural occurrence.1 The evidence is overwhelming and undeniable.
We’re already seeing changes. Glaciers are melting, plants and animals are being forced from their habitat, and the number of severe storms and droughts is increasing.
The number of Category 4 and 5 hurricanes has almost doubled in the last 30 years.2
Malaria has spread to higher altitudes in places like the Colombian Andes, 7,000 feet above sea level.3
The flow of ice from glaciers in Greenland has more than doubled over the past decade.4
At least 279 species of plants and animals are already responding to global warming, moving closer to the poles.5
If the warming continues, we can expect catastrophic consequences.
Deaths from global warming will double in just 25 years -- to 300,000 people a year.6
Global sea levels could rise by more than 20 feet with the loss of shelf ice in Greenland and Antarctica, devastating coastal areas worldwide.7
Heat waves will be more frequent and more intense.
Droughts and wildfires will occur more often.
The Arctic Ocean could be ice free in summer by 2050.8
More than a million species worldwide could be driven to extinction by 2050.9
There is no doubt we can solve this problem. In fact, we have a moral obligation to do so. Small changes to your daily routine can add up to big differences in helping to stop global warming. The time to come together to solve this problem is now.
TAKE ACTION
1 According to the Intergovernmental Panel on Climate Change (IPCC), this era of global warming "is unlikely to be entirely natural in origin" and "the balance of evidence suggests a discernible human influence of the global climate."2 Emanuel, K. 2005.

Humanity is sitting on a ticking time bomb. If the vast majority of the world's scientists are right, we have just ten years to avert a major catastrophe that could send our entire planet into a tail-spin of epic destruction involving extreme weather, floods, droughts, epidemics and killer heat waves beyond anything we have ever experienced. If that sounds like a recipe for serious gloom and doom -- think again. From director Davis Guggenheim comes the Sundance Film Festival hit, AN INCONVENIENT TRUTH, which offers a passionate and inspirational look at one man's fervent crusade to halt global warming's deadly progress in its tracks by exposing the myths and misconceptions that surround it. That man is former Vice President Al Gore, who, in the wake of defeat in the 2000 election, re-set the course of his life to focus on a last-ditch, all-out effort to help save the planet from irrevocable change. In this eye-opening and poignant portrait of Gore and his "traveling global warming show," Gore also proves himself to be one of the most misunderstood characters in modern American public life. Here he is seen as never before in the media - funny, engaging, open and downright on fire about getting the surprisingly stirring truth about what he calls our "planetary emergency" out to ordinary citizens before it's too late. With 2005, the worst storm season ever experienced in America just behind us, it seems we may be reaching a tipping point - and Gore pulls no punches in explaining the dire situation. Interspersed with the bracing facts and future predictions is the story of Gore's personal journey: from an idealistic college student who first saw a massive environmental crisis looming; to a young Senator facing a harrowing family tragedy that altered his perspective, to the man who almost became President but instead returned to the most important cause of his life - convinced that there is still time to make a difference. With wit, smarts and hope, AN INCONVENIENT TRUTH ultimately brings home Gore's persuasive argument that we can no longer afford to view global warming as a political issue - rather, it is the biggest moral challenges facing our global civilization. Paramount Classics and Participant Productions present a film directed by Davis Guggenheim, AN INCONVENIENT TRUTH. Featuring Al Gore, the film is produced by Laurie David, Lawrence Bender and Scott Z. Burns. Jeff Skoll and Davis Guggenheim are the executive producers and the co-producer is Leslie Chilcott.
