Title: What you need to know

  • What you need to know
  • By the children of P.S.173

What is Global Warming?
  • Global Warming is an increase of the average
    temperature of our earths atmosphere, especially
    a sustained increase able to cause climatic

Why should we care?
  • Because the earth is getting so warm, its
    destructing things. For instance
  • In 2002, Colorado, Arizona and Oregon endured
    their worst wildfire seasons ever.
  • Also that same year, droughts were creating
    severe dust storms in Montana, Colorado, and
    Kansas and floods caused hundreds of millions of
    dollars in damage in Texas, Montana, AND North
  • Since the 50s, snow fall has decreased about
    60 and winter seasons have shortened in some
    areas of the Cascade Range in Oregon and
  • In 2003, heat waves killed over 20,000 people
    in Europe and more than 1,500 deaths in India.
  • And in the Arctic area, the perennial polar
    ice cap is declining at a rate of 9 per decade!

Whats going to happen if we dont try to stop
  • If we dont try to put a stop to all the
    madness, many things may occur like
  • Melting glaciers, early snowmelt, and severe
    droughts will cause more dramatic water shortages
    in the American West
  • There will be rising sea levels that will lead
    to coastal flooding on the Eastern seaboard in
    Florida, and in other areas, such as the Gulf of
  • There will be a lot of trouble in forests,
    farms, and cities that have to do with more
    mosquito diseases and other pests.
  • And worse of all, there will be a disruption
    of habitats such as coral reeds, and alpine
    meadows that could drive many plant and animal
    species to EXTINCTION!

What are the natural causes of Global Warming?
  • There are many causes of global warming such as
  • Carbon dioxide and other air pollution that is
    being collected in the air acts like a thickening
  • It traps the suns heat and causes the entire
    planet to warm up
  • Coal burning power plants are the largest U.S.
    source of carbon dioxide pollution they produce
    over 2.5 billion tons each year.
  • Automobiles also cause carbon dioxide

Is there any good news to this?
  • Yes there is! There is
  • Technology the technology that lives today
    makes the cars run cleaner and burn less gas now
    thats smart!
  • It also modernizes power plants and generates
    electricity from nonpolluting sources that cuts
    our electricity use through energy efficiency
  • The only thing is can we put these solutions
    to use?!

What is the government doing about it?
  • In February of 2004, consultants to the
    Pentagon released a report showing the
    possibilities of impacts of abrupt climate change
    on national security. The study also concluded
    that global warming could make large areas of the
    world un-livable and could cause massive food and
    water shortages, giving widespread migrations and
  • Many of global warming attacks effects are
    already going under high investigation.

Which country is the largest source by global
warming pollution?
  • The United States is the largest source of
    global warming! Although Americans make up only
    4 of the worlds population, we can produce up
    to 25 of the carbon dioxide pollution from
    fossil-fuel burning the largest share of any
  • In fact the United States emits more carbon
    dioxide than China, India, and Japan combined.
    Apparently America needs to take a time out and
    think about what theyre doing! And they should
    start doing something about it.

What is the Greenhouse Effect?
  • It may be hard to believe that people may change
    the earths average temperature. Scientists think
    that the things we do affect Earth, letting out
    Greenhouse Gases. The Greenhouse effect is
    important. Without the Greenhouse effect, the
    Earth would not be warm enough for humans to
    live. But if the Greenhouse effect becomes
    stronger, the Earth may become warmer than the
    temperature that usually occurs. Even a little
    extra heat can cause harm to us, animals humans
    and plants.

How can we cut this stuff short?
  • Its actually quite simple. By just
    reducing the amount of pollution from vehicles
    and power plants we can make the world a better
    place. Right away we should put good existing
    technology to good use, you know, building
    cleaner cars and more modern electricity
    generators into widespread use. We could increase
    our reliance on renewable energy sources such as
    wind, sun, and geothermal. And we can manufacture
    more efficient appliances and conserve energy.

Why isnt the technology more commonplace now?
  • Even though the technology is around, the
    corporate and political will to put them into
    widespread use does not exist. Many companies in
    the automobile and energy businesses put pressure
    on the White House and Congress to stop the new
    laws and regulations as they would not make the
    business they do now. They dont want to have
    such changes because then the amount of money
    would go down rather than up. It would totally
    destroy their industries. If we want progress,
    were going to have to demand it and be a little
    more persuasive.

Is it even possible to cut power plant pollution
short and still have enough electricity?
  • Of course! First we must use more efficient
    appliances and equipment in our homes and offices
    to reduce our electrical needs. We can take out
    the old, and bring in the new, you know? For
  • We can take out the coal-burning power plants
    that generate most of our electricity and use
    cleaner plants instead.
  • We can increase our use of renewable energy
    sources such as the wind and sun. Some states are
    moving in that direction, actually. California
    has required its largest utilities to get 20 of
    their electricity from renewable sources by 2017,
    and New York has pledged to compel power
    companies to provide 25 of the states
    electricity from renewable sources by 2013.

How can we cut car pollution short?
  • There is in fact technology to reduce the global
    warming pollution from cars and light trucks of
    all sizes are available at this moment! Theres
    no point to just sit around and hope that
    hydrogen fuel cell vehicles will solve the
    problem in the future. Hybrid gas-electric
    engines can cut global warming pollution by
    one-third or more today. Honda and Toyota have
    hybrid sedans on the market, and minivan and SUV
    models will soon be on the market from numerous
  • Unfortunately, automakers arent doing all
    they can do. Theyve being using a legal loophole
    to make SUVs less fuel efficient than they could
    be. And its not like it doesnt matter because
    the model isnt big the model is HUGE! The
    popularity of these vehicles has generated a 20
    increase in transportation-related carbon dioxide
    pollution since the early 1990s. Closing the
    loophole and requiring SUVs, minivans and pick-up
    trucks to be as efficient as cars would cut 120
    million tons of carbon dioxide pollution a year
    by 2010. If they used the technology they have at
    this moment to raise fuel economy standards for
    new cars and light trucks to a combined 40mpg,
    carbon dioxide pollution would eventually drop
    650 million tons per year as these vehicles
    replaced older models.

What can WE do?
  • Ok, so now you know what they can do but what
    can WE do? You can do a lot of things a couple
    things are
  • Make your voice louder. We need laws that will
    bring our nation to the important solutions of
    global warming.
  • Choose an efficient vehicle A car that gets 20
    mpg (miles per gallon) will emit about 50 tons of
    carbon dioxide over its entire lifetime. A car
    getting 40 mpg will emit half that much. When
    buying your car you should make sure that you buy
    the least-polluting car.
  • Drive smart. Get your engine fired up and keep
    your tired inflated at all times. Those things
    will definitely help energy.
  • Drive less. When you can, pick alternatives such
    as public transportation, biking, walking, and
    maybe even carpooling.
  • Replace your light bulbs with compact
    fluorescent bulbs. They might be more expensive
    than the incandescent bulbs most people use, they
    last 10 times longer!
  • Choose renewable energy over everything else.
    If you live in a state that you can pick the type
    of energy you want, you should pick renewable
  • Join NRDC. You can help secure the changes that
    will stop global warming by joining NRDC, one of
    the most effective environmental groups in the

Thank You
  • I hope after listening to the few but true
    points you make the right choice. There is so
    much that can be done for this town, this state,
    this country, but most importantly this world.
    Living on this earth you notice the little things
    like daisies growing on fresh green grass, or the
    clouds forming into your favorite past-time
    favorite characters from baby books you read in
    kindergarten. The world has done so much for you,
    now its time you do something for the world.
