    • Climate Change and Global Warming
      By Kerry and Lauren
    • Green House Effect- The heating of Earth’s surface and atmosphere from solar radiation being absorbed and emitted by the atmosphere mainly by water vapor and carbon dioxide
      Global Warming- The increase in average temperatures of Earth and the atmosphere due in part to increased carbon dioxide levels
      Climate Change- The overall transformation of Earth’s climate over a long period of time, due to plate tectonics, Earth’s orbital motions, solar activity, and volcanic eruptions
      Definitions
    • The fossil fuels we are burning contribute to higher concentrations of methane, carbon dioxide, and nitrous dioxide. These gases are called greenhouse gases. They create a thick blanket around our globe and trap lots of heat, causing global warming. This turns the Earth into something like a greenhouse.
      *Not that it is important to remember both that the greenhouse effects occurs naturally, but that it has been a bigger issue because of mankind’s emissions of greenhouse gases into the atmosphere
      Connecting It All Together
      • Green house gases are the main cause.
      • Research from the past and present shows that carbon dioxide levels have increased tremendously due to the emission of more carbon dioxide levels
      • Emissions come from coal and oil that we burn for energy
      • Humans are the main cause for global warming
      Causes of Global Warming
    • Consequences
      • Threats to People and Health
      • Very strong heat waves
      • Spread of disease
      • Worsening air quality
      • Extreme/ more dangerous weather
      • More wildfires and flooding
      • Draught
      • Stronger Hurricanes
      • Thinning Ice/ Rising Seas
      • Arctic ice is shrinking
      • Rise in sea level
      • Glaciers melting
      • Biodiversity Loss
      • Decrease in Polar Bear population
      • Acidifying Oceans
      • Coral Bleaching
      • Moving habitats
      • Threats to Western Forests
      • If there are food shortages due to dying crops from the rising temperature, price of food will raise and more will go without
      • Some governments, like ours, our trying to go “Green” but they don’t know how much it is going to cost
      • It could be worse to do nothing in which the economy could fail us completely
      Impacts on Economy
      • Write letters to local government asking for a more eco-friendly town
      • Replace regular light bulbs with fluorescent lights
      • Unplug unused appliances
      • Recycle and Reuse
      • Cut back on Paper
      • Educate yourself and others
      • Plant Trees
      • Carpool
      Fighting Back
      • Some scientists believe that human activities don’t disrupt Earth’s climate
      • Some say our most reliable sources do not show a trend of global warming since they began taking readings 23 years ago
      • All predictions are based on computer models, not real life. Some think this does not give an accurate reading
      • Some think a small amount of global warming could benefit the Earth and civilization as a whole.
      • It would be extremely expensive to quickly fix global warming and would not be very effective
      Arguments
      • We believe that global warming is a serious issue and does need to be addressed.
      • The reason for this is due to the serve consequences that we will and already are facing. For example, the poles are shrinking, sending huge chunks of melting ice into the oceans. Arctic animals like the polar bears are dying out because this change. Coral Reefs are being bleached and drained of their color
      • Also, raising temperatures are causing crops to wither and die, depleting the food storage of the world. If it got too bad we may face food shortages and more hunger
