PPT-Why should we be concerned about Global Warming?

Many people consider that Global Warming is the greatest environmental threat of the 21 st Century However during the 80s and early 90s scientists argued about the causes and effects of global warming . What are the threats?. What are the facts?. What is best to do?. Objectives. Examine in a thorough, yet understandable way, the theory of man made global warming. Analyze its plausibility. Review other factors, besides CO2, that may also impact the climate.. Ned Bair . US Army Corps of Engineers Cold Regions Research and Engineering Laboratory.

Simulation of how climate will change. Run forward to make predictions of the future. Run backwards. Run without carbon dioxide increase. By Matthew and saeb . What is global warming. Carbon dioxide and other air pollution that is collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up. Coal-burning power plants are the largest U.S. source of carbon dioxide pollution -- they produce 2.5 billion tons every year. Automobiles, the second largest source, create nearly 1.5 billion tons of CO2 annually. Created and presented by Brandi graham. What is global warming and why is it happening? . Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth's climate.
