  1. 1. GLOBAL WARMING     <ul><li>By Maggie & Jeremy </li></ul>
  2. 2. <ul><ul><li>The Greenhouse Effect is when gases in the atmosphere reflect the sun’s radiation back onto earth </li></ul></ul><ul><ul><li>Climate Change is a significant and lasting change in the weather patterns over periods ranging from decades to millions of years </li></ul></ul><ul><ul><li>Global Warming is the gradual increase of the world’s average temperature, believed to be primarily caused by humans </li></ul></ul>What is the Greenhouse Effect? Climate Change? Global Warming?
  3. 3. How They Go Together… <ul><li>Greenhouse gases keep heat and energy in the atmosphere, leading to global warming (rising of global temperature) </li></ul><ul><li>This change in temperature leads to climate changes </li></ul>
  4. 4. Primary Causes of Global Warming: <ul><ul><li>The build up of CO2 in our atmosphere- reflects radiation back to Earth </li></ul></ul><ul><ul><li>Excessive greenhouse gases in our atmosphere from cars, power plants, and heating our homes with oil and natural gases </li></ul></ul>
  5. 5. Consequences of Global Warming <ul><ul><li>Increased risk of flash floods </li></ul></ul><ul><ul><li>Many foods will no longer be available (Ex: nuts, fruits, vegetables…) </li></ul></ul><ul><ul><li>Hot, dry, weather leading to wildfires </li></ul></ul><ul><ul><li>Health: Heat waves </li></ul></ul><ul><ul><li>Wildlife: losing many species such as polar bears </li></ul></ul><ul><ul><li>Loss of many glaciers </li></ul></ul><ul><ul><li>Rising sea levels </li></ul></ul><ul><ul><li>Increasing amounts of precipitation </li></ul></ul><ul><ul><li>Stronger hurricanes and other natural events </li></ul></ul><ul><ul><li>Changing ecosystems </li></ul></ul>
  6. 6. The Impact on the Economy: <ul><li>  Predictions in China show that agricultural output will decrease by 37% in the next 50 years </li></ul><ul><li>The UN predicts Global Warming will cost China 7.8 billion dollars </li></ul><ul><li>Longer summers have led to a longer allergy season and increased health care costs for asthma and people who suffer from allergies </li></ul><ul><li>Increased air pollution kills 1,000 U.S residents every 1°C increase in temperature </li></ul>
  7. 7.   How to fight Global Warming: <ul><li>Reduce, Reuse, Recycle </li></ul><ul><li>Use less heat and air conditioning </li></ul><ul><li>Drive less and drive smart </li></ul><ul><li>Buy energy efficient products </li></ul><ul><li>Plant a tree </li></ul><ul><li>EDUCATE OTHERS! </li></ul>
  8. 8. <ul><li>  Sunspots are the cause of the earth’s rising temperature (TRUE) </li></ul><ul><li>Efforts by state governments to reduce greenhouse gas emissions are even more expensive and are threatening to bust state budgets (CONTROVERSIAL) </li></ul><ul><li>Human activities do not disrupt the Earth (FALSE) </li></ul>Argument(s) against Global Warming
  9. 9.   OUR OPINIONS: <ul><li>  Humans and natural causes BOTH have an effect </li></ul><ul><li>Sunspots, El Nino=natural causes </li></ul><ul><li>Human CO2 emissions, tar and gas buildup from factories=Humans </li></ul><ul><li>Hopefully we can all work together to make a difference and help STOP Global Warming  </li></ul>
