2. WHAT IS GLOBAL WARMING?
 Increases in global
temperature as a result
of an accumulation of
greenhouse gases in the
atmosphere

3. WHAT ARE GREENHOUSE
GASES?
 Substances including carbon dioxide,
methane and chlorofluorocarbons. These
gases trap the sun's heat as it is radiated from
the earth and prevent it from escaping back
into space somewhat like the glass panels of a
greenhouse

4. WHAT IS THE GREENHOUSE
EFFECT?
 Something that occur as a result of
greenhouse gases trapping the heat from the
sun and keeping it close to the earth
 The earth has a natural greenhouse effect
that’s keeps it about 60 degrees warmer than
it would be otherwise. This enables us to live
comfortably on earth.

7. CAUSES OF GLOBAL WARMING
 Burning fossil fuels to




run cars and trucks,
heat homes and power
factories
Agriculture
Deforestation
Landfills
Industrial production
and mining

8.  When trees cut down for development,
agriculture and other purposes they not only
can't use up the carbon dioxide in the air but
they actually release it when they decay or are
burned

9. GLOBAL WARMING EFFECT
 A perpetual El Nino-like state, with higher
temperatures, wetter winters and drier summers.
This would mean more flooding in winter and
spring, but more water shortages in late summer
and fall
 A rise sea level resulting in submersion of low-lying
parts of coastal highways and land, increased
coastal erosion, changes in habitat, and saltwater
intrusion into fresh water

10.  a possible increase in human diseases,as warm
weather boosts tick and other parasite
populations and fosters the spread of viruses
and bacteria
 Loss of forest lands as a results of forest fires,
wind storms, and insect infestations

11.  Increased risk of extinction for salmon and other
marine life,as ocean temperature rise, nutrient
levels drop, and habitat changes
 Building and roads close to the water could be
flooded and they could not be suffer damage
from hurricane and tropical storm

12. Global warming at the extremes of the earth: Habitats and
cultures everywhere react to climate's rapid changes

15. HOW TO REDUCE EMISSION OF
GREENHOUSE GASES
 Drive less frequently. Use alternative
methods of transportation such as buses,
carpools , bicycling, or walking
 Buy more energy efficient vehicles to helps
reduce use of fossil fuels such as coal and
gasoline
 Use cleaner alternative fuels such as methane
and propane

16.  Buy products that feature reusable, recyclable,
or reduced packaging to save the energy
required to manufacture new containers
 Use non-fossil energy, such as solar power and
wind power
 Weatherize buildings to conserve energy
 Plants tees
