Global Warming
  • Kaitlyn Hamner

What is Global Warming?
  • Global Warming is defined as the increase of the
    average temperature of the earth.
  • The Greenhouse gases traps the
  • Suns energy and warms the earth
  • Global Warming is changing the
  • rhythms of climate that all living
  • things have come to rely on

  • Average temperatures have climbed 1.4 degrees
    Fahrenheit or 0.8 degree Celsius around the world
    since 1880 and much of this has occurred in
    recent decades
  • The rate of warming is increasing. The 20th
    century's last two decades were the hottest in
    400 years
  • It is said that the earths average temperature
    will rise between 2 and 10 degrees fahrenheit by
    the end of the century
  • Coral reefs are highly sensitive to small changes
    in water temperature and suffered the worst
    bleaching ever recorded in 1998 with some areas
    seeing bleach rate of 70 percent.

Causes of Global Warming
  • Several Greenhouse Gases that are responsible for
    the warming
  • The combustions of fossil fuels from cars,
    factories and electricity production
  • CO2 is responsible for the highest amount of
  • change and warming
  • Other gases that are responsible
  • are methane, nitrous oxide,
  • fertilizer, and gases used for
  • refrigeration
  • The loss of forest which store
  • CO2 is another cause

Effects of Global Warming
  • Ice is melting worldwide, especially in the
    earths poles. NASA has reported that the arctic
    sea ice has decreased in size by 10 in the past
    30 years
  • The rate of sea level rising has increased over
    the past ten years.
  • Some foxes and alpine plants have miragted north
    to cooler climates
  • On average the worldwide precipitation levels,
  • rain and snowfall, has greatly increased
  • There has been a decline in the number of
  • Adelie penguins in Antarctica and the number
  • of breeding pairs has fallen from 32,000 to
    11,000 in the past
  • 30 years.

Solutions to Global Warming
  • Take the bus, carpool, walk, or ride your bike
  • Find a recycling depot close to you
  • If you need a new car, look into a hybrid one
  • Find an alternate fuel source
  • Educate people on the problems and solutions
  • Plant a tree!
  • Reduce your carbon footprint
  • There are many other ways in which you can help
    prevent further damages and try and reverse the
    ones that are already present

Alternate Energy Sources
  • Some ways that we can power the world in a
    cleaner way are
  • Biofuel
  • Fuel Cells
  • Geothermal Energy
  • HydroPower
  • Solar Energy
  • Wind Power
