CLIMATE CHANGEWhat is climate change?A substantial change in the
region average weather pattern including average temperature, precipitation & wind
(Earth Reform, 2012). refers to any long-term
change in normal weather patterns caused by a process that adjusts the climate, such as a volcanic eruption
(Arkive, 2013)
Climate Change
Climate Change
CAUSES
Burning of fossil fuel for energy-
• Coal is burn to produce electricity from coal power plants,
• gas to heat homes.• oil to drive cars.
Contributing to production of greenhouse gases.
Climate Change
Climate Change
Causes ……..Increase in population- • 7 billion people• more people burning fossil fuels
for energy. • By driving cars.
• Heating our homes with oil, gas & electricity.
o we release greenhouse gases into the atmosphere.
o In 2005, about 27 billion tones of CO2 released into the atmosphere
(Arkives, 2013).Climate Change
Climate Change
Causes…….Livestock and agricultural production
o Clearing of land for farming,
o contributes to deforestation.
o Transportation of food across the world
results in burning of fosil fuel.
o Fertilizer production for crops
o Methane gas emitted by livestock
contributes to emissions. CH4 has increase
by 148% after industrial revolution.
(Earth Reform, 2012).
Climate Change
Climate Change
CausesDeforestation and other changes
to the use of land.Man-Made Activities
o Wood loggingo Building houseso Farming
forests are a natural ‘sink’ of carbon dioxide.
plants absorb CO2 from the air into their trunks, branches and leaves.
When forests are cleared or burned, their stored carbon is released back into the air, contributing to global warming
Deforestation Account for 23% of man-made CO2 emissions.
( Arkives, 2013)
Climate Change
Climate Change
Causes……..Other man-made chemical
reactions.
1.Fluorinated gases-• Man-made gases use in AC,
refrigerators, aerosols.
• High global warming gases greatly depleting the ozone layer.
2. CO2, and CH4 from breakdown of waste in landfills.
(Earth Reforms, 2012)
Climate Change
Climate Change
EffectsFlooding and Draught
Change in precipitation pattern.
Parts of the world will be draught & others floods.
Affect crop field -food shortage , fresh water supply & housing.
(Earth Reform, 2012)
Climate Change
Climate Change
Effects……..
Poor Health & Deatho Polluted atmosphere-increased
respiratory illness.o CC causes over 800, 000 deaths
annually (WHO, 2012).o 150, 000 of these deaths from
air pollution.o Children more vulnerable to
poor ambient air quality. (WHO, Earth Reform, 2012)
Climate Change
Climate Change
Effects ………Global Warming
Increase in planet average temperature due to greenhouse gases.
Extreme weather pattern shift in all regions of the world
(Earth Reform, 2012)
Climate Change
Climate Change
Effects ……..Extinction of many species
& birds1.Due to Extreme weather
conditions.
2.Chemical fishing etc.
o polar birds, turtle, dolphins etc.
(IPSOR, 2013)
Climate Change
Climate Change
Effects……..Risk of Human Extinction.
• Natural food supply shortage
• Polluted rivers, lakes & oceans with toxic materials.
• Shortage of water supply.• Polluted air –High risk of
airborne diseases (Earth Reform, 2012)
Climate Change
Climate Change
Prevention
Limiting our electricity use at home.
Use less hot water
Turn off the lights , heater , TV etc when not needed.
(Earth Reform, 2012)
Climate Change
Climate Change
Prevention …….
Better Transport Choices to reduce carbon emissions.
o Use fuel efficient cars
o Take public transport
Climate Change
Climate Change
Prevention ……
• Better Government policies mandating stricter laws on pollution causing industries ( Earth Reform, 2012).
Legislation in UKo Climate Change Act 2008
o Climate Change (Scotland) Act 2009
Climate Change
Climate Change
Prevention……• Alternative Clean Energy
sources.Renewal energyo Biomass
o Solar energy
o Wind turbines
o Hydro electricity etc.(Bionomic fuel, 20130)
Climate Change
Climate Change
Prevention……..
• Better recycling & waste management program.

Climate Change
ConclusionYou can help tackle climate change by:• reducing, reusing and recycling products that you buy
• walk or take public transport to limit car usage.
• insulate your home better so that you do not need to use so much energy to heat it.
• tell your friends and family about climate change and what they can do to help.
Although each action may be small, if many people make small changes it will add up to make a big difference.
