  4. 4. Global Warming is a term used to describe gradual increase in the earth’s atmosphere temperatures across the whole planet. This warming trend to be appeared during a period when human activities were beginning to increase the carbon dioxide (CO2) and other greenhouse gases in the atmosphere. Such as from the burning of fossil fuels and deforestation. These findings are recognized by the national science academies of all major industrialized nations.
  6. 6. Carbon dioxide and other global warming pollutants are collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up. Although local temperatures fluctuate naturally, over the past 50 years the average global temperature has increased at the fastest rate in recorded history. Scientists say that unless we curb the emissions that cause climate change, average U.S. temperatures could be 3 to 9 degrees higher by the end of the century. The United States Global Change Research Program (which includes the Department of Defense, NASA, National Science Foundation and other government agencies) has said that ”Global Warming is unequivocal and primarily human-induced” and “climate changes are underway in the United States and are projected to grow.”
  8. 8. This has been the warmest decade since 1880. In 2010, global surface temperatures tied 2005 as the warmest on record, according to the National Oceanic and Atmospheric Administration. Scientists say that the earth could warm by an additional 7.2 degrees Fahrenheit during the 21st century if we fail to reduce emissions from burning fossil fuels, such as coal and oil. This rise in average temperature will have far-reaching effects on the earth's climate patterns and on all living things. Many of these changes have already begun.
  9. 9. WEATHER PATTERNS Hot, dry weather led to a record-setting 2006 wildland fire season with close to 100,000 fires reported and nearly 10 million acres burned, 125 percent above the decade's average.
  10. 10. HEALTH ISSUES The number of pollen allergy and asthma sufferers has increased worldwide over the last several decades. Some researchers have suggested that this could be an early health effect of human-caused climate change. Air pollution makes allergies worse: Diesel exhaust particles can interact with pollen and deliver it deeper into the lung. Rising temperatures increase ground-level ozone smog production, which presents a serious threat to asthmatics.
  11. 11. WILDLIFE Scientists report that some polar bears are drowning because they have to swim longer distances to reach ice floes. Unless we take effective action now, the polar bear will likely become extinct in Alaska by 2050.
  12. 12. GLACIERS & SEA LEVELS Global sea level has already risen by 4 to 8 inches in the past century, and the pace of sea level rise appears to be accelerating. The Intergovernmental Panel on Climate Change predicts that sea levels could rise 10 to 23 inches by 2100, but in recent years sea levels have been rising faster than the upper end of the range predicted. In the 1990s, the Greenland ice mass remained stable, but the ice sheet has increasingly declined in recent years. This melting currently contributes an estimated one-hundredth of an inch per year to global sea level rise.
  13. 13. CAN WE STOP IT?
  14. 14. Here's the good news: technologies exist today to make cars that run cleaner and burn less gas, modernize power plants and generate electricity from nonpolluting sources, and cut our electricity use through energy efficiency. The challenge is to be sure these solutions are put to use. NRDC is tackling global warming on two main fronts cutting pollution and expanding clear energy. Transitioning to a clean energy economy will bring new jobs and reduce air pollution. We can’t afford to wait.
  15. 15. Here’s some little things that we can do to reduce Global Warming • Set limits on Global Warming pollutions • Invest in green jobs and clean energy • Drive smarter cars • Create green house and buildings • Built better communities and transportation networks
  16. 16. Earth has given us an endless bless. And earth just ask one thing, LOVE EARTH THE WAY EARTH LOVES YOU THANKS FOR YOUR ATTENTIONS
