  • I have come to the conclusion that we all have a little blame global warming and its consequences and guilt even more politicians who do not slow down.

Global warming and Its Effects

  1. 1. Global Warming And Its Effects
  2. 2. What is Global Warming? It is the phenomenon that shows an average rise in the temperature of the Earth’s atmosphere and oceans in recent decades.Global Warming 2
  3. 3. Causes of Global Warming • Variations in solar activity • Fluctuations in ocean currents • Volcanic eruptions • Greenhouse gasesGlobal Warming 3
  4. 4. The Greenhouse Effect The "greenhouse effect" is the warming that happens when certain gases in Earths atmosphere trap heat. These gases let in light but keep heat from escaping, like the glass walls of a greenhouse.Global Warming 4
  5. 5. The Greenhouse Effect ExplainedGlobal Warming 5
  6. 6. A Reality in Pictures • Glacier National Park, USA 1932 • Glacier National Park, USA 1988Global Warming 6
  7. 7. A Reality in Pictures • Peru, 1980 • Peru, 2002Global Warming 7
  8. 8. A Reality in Pictures • Kilimanjaro, 1970 • Kilimanjaro, 2000Global Warming 8
  9. 9. A Reality in Pictures • Nepal, 1978 • Nepal, 2004Global Warming 9
  10. 10. A Reality in Pictures Even more obvious from space, these pictures of the North Polar cap from NASA show a melting of 25% in 25 years.Global Warming 10
  11. 11. Effects of Global Warming • Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice. • Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years. • Sea level rise became faster over the last century. Earth after global • Some butterflies, foxes, and alpine plants have warming moved farther north or to higher, cooler areas. • Precipitation (rain and snowfall) has increased across the globe, on average.Global Warming 11
  12. 12. Future Effects of Global Warming• Other effects could happen later in the century, if warming continues. Sea levels are expected to rise Hurricanes and other storms are Floods and droughts will become between 7 and 23 inches (18 and 59 likely to become stronger more common centimeters)Global Warming 12
  13. 13. What Should We Do?By using energy wisely, we could help reduce the demand for fossil fuel,which in turn could reduce the global warming. We can do the following: • Reduce, • Use the “Off” Reuse, Recycle switch • Change a light • Plant a tree bulbGlobal Warming 13
  14. 14. Stop Global WarmingGlobal Warming 14
