  1. Stop Global Warming Save the EARTH.

  2. Introduction: • Global Warming is the increase in average temperature in the Earth’s near-surface air and ocean since the mid-twentieth century and its projected continuation. • A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. • Climate change might harm human welfare, but so would climate change policy. Policy makers should assess and weigh both sets of risks before deciding on a course of action.

  3. Facts: • Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies. • The Arctic is feeling the effects the most. Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to the multinational Arctic Climate Impact Assessment report compiled between 2000 and 2004.

  4. More Facts: Model of Projections in Arctic sea ice in the 2050s compared to the 1950s (based on the Geophysical Fluid Dynamics Laboratory's R30 atmosphere-ocean general circulation model).

  5. MORE… • Glaciers and mountain snows are rapidly melting—for example, Montana's Glacier National Park now has only 27 glaciers, versus 150 in 1910. In the Northern Hemisphere, thaws also come a week earlier in spring and freezes begin a week later.

  6. Some Effects of Global Warming:

  7. Say goodbye to some Cultural monuments…. • The World Monuments Fund recently added “global warming” as a threat in their list of the top 100 threatened cultural landmarks. “On Herschel Island, Canada, melting permafrost threatens ancient Inuit sites and a historic whaling town. In Chinguetti, Mauritania, the desert is encroaching on an ancient mosque. In Antarctica, a hut once used by British explorer Captain Robert Falcon Scott has survived almost a century of freezing conditions but is now in danger of being engulfed by increasingly heavy snows.”

  8. Say goodbye to good Salmons and Lobsters….. Lobsters thrive in the chilly waters of New England, but recent numbers show that as those waters have warmed up, “the big-clawed American lobster—prized for its delicate, sweet flesh—has been withering at an alarming rate from New York state to Massachusetts.” Get ready for a lot more chicken dinners: Wild pacific salmon have already vanished from 40 percent of their traditional habitats in the Northwest and the NRDC warns warmer temperatures are going to erase 41 percent of their habitat by 2090.

  9. Say goodbye to FRENCH FRIES! • Scientists from the Consultative Group on International Agricultural Research say warmer temperatures are killing off wild relatives of potato and peanut plants, “threatening a valuable source of genes necessary to help these food crops fight pests and drought.”

  10. Species Disappear • The latest report from the World Conservation Union says that a minimum of 40 percent of the world’s species are being threatened and global warming’s one of the main culprits.

  11. Dying of polar bears • A recent study completed by the U.S. Geological Survey shows that cannibalism—while brutal—may be the least of the bear’s problems. Many are also drowning, unable to swim in the increased spaces between melting sea ice. Two-thirds of them may be gone by 2050.

  12. More stray cats.. • Global warming has extended the cat-breeding season beyond spring, which is the usual time for a kitten boom. The kittens are often homeless and end up in animal shelters. And remember, “The trouble with a kitten is that/ Eventually it becomes a cat.”

  13. More Hurricanes • Over the past century, the number of hurricanes that strike each year has more than doubled. Scientists blame global warming and the rising temperature of the surface of the seas.

  14. More Floods • During the summer of 2007, Britain suffered its worst flood in 60 years. Scientists point the finger directly at global warming, which changed precipitation patterns and is now causing more “intense rainstorms across parts of the northern hemisphere.”

  15. More Volcanic Eruptions • British scientists warn of another possible side effect of climate change: A surge of dangerous volcanic eruptions.

  16. Death By Smog • Three words you really don’t want in your obit: “Death by Smog.” Yet Canadian doctors say smog-related deaths could rise by 80 percent over the next 20 years. And since warm air is a key ingredient in smog, warmer temperatures will increase smog levels.

  17. 5 Deadliest Effects of Global Warming • Spread of Disease: like insects migrating and bringing plague • Warmer waters and More Hurricanes : oceans will rise and more hurricanes • Increased probability and intensity of Droughts and Heat waves • Economic consequences • Polar ice caps Melting: the sea levels will rise

  18. Solutions

  19. The solutions are: • Replace frequently used light bulbs with compact fluorescents. • Run your dishwasher only with full load. • Replace old appliances. • Bring back the clothes line. • Recycle! • Save energy • STOP THE POLLUTION!
