  • 1. GLOBAL WARMING Dont wait till the last minute!!!

2. WHAT IS GLOBAL WARMING? Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans 3. GLOBAL WARMING Global warming is primarily a problem of too much carbon dioxide (CO2) in the atmospherewhich acts as a blanket, trapping heat and warming the planet. As we burn fossil fuels like coal, oil and natural gas for energy or cut down and burn forests to create pastures and plantations, carbon accumulates and overloads our atmosphere. Certain waste management and agricultural practices aggravate the problem by releasing other potent global warming gases, such as methane and nitrous oxide. See the pie chart for a breakdown of heat-trapping 4. FACTS ABOUT GLOBAL WARMING The concentration of carbon dioxide has increased an average of about 1.8 ppm per year over the past two decades. According to NASA, the ten warmest years of record have occurred in the past fifteen-year period (1998-2013). About 75% of the annual increase in atmospheric carbon dioxide is due to the burning of fossil fuelslobal Warming 5. CARBONDIOXIDE THE KILLER 6. CONSEQUENCES . Changes resulting from global warming may include rising sea levels due to the melting of the polar ice caps, as well as an increase in occurrence and severity of storms and other severe weather events. 7. GREEN HOUSE EFFECT The Consequences of Global Warming As the concentration of greenhouse gases grows, more heat is trapped in the atmosphere and less escapes back into space. This increase in trapped heat changes the climate and alters weather patterns, which may hasten species extinction, influence the length of seasons, cause coastal flooding, and lead to more frequent and severe storms. 8. WHY YOU NEED TO ACT NOW Substantial scientific evidence indicates that an increase in the global average temperature of more than 2F above where we are today poses severe risks to natural systems and human health and well-being. To avoid this level of warming, the U.S. needs to reduce heat-trapping emissions by at least 80 percent below 2000 levels by 2050. Delay in taking such action will require much sharper cuts later, which would likely be more difficult and costly. 9.
