The changes in the surface air
temperature, referred to as the
global temperature, brought
about by the enhanced
greenhouse effect, which is
induced by emissions of
greenhouse gases into the air.

3.
Carbon Dioxide (CO2)
Fossil fuels (coal, oil, natural gas)

4.
Example of the
Greenhouse Effect
The Sun’s energy
passes through the
car’s windshield.
This energy (heat)
is trapped inside
the car and cannot
pass back through
the windshield,
causing the inside
of the car to warm
up.

COP15- Copenhagen
Climate Conference
 An overview of the Climate Change Conference
(also known as COP 15), held in copenhagen,
Denmark, in the middle of December, 2009.
 There was a lot of hope and optimism before this
conference that a meaningful climate negotiation
could be agreed to, as climate change concerns
are increasing rapidly.
 Instead, a mixture of posturing from nations such
as China and the US, and the inability for nations
to agree on numerous issues led to a meeting
failure.

What can you do to help
solve the problem?

16.
Turn off your computer or the TV
when you’re not using it.
Take shorter showers. Heating water uses energy.
Keep rooms cool by closing the blinds, shades,
or
curtains.
Turn off the lights when you leave a room.
Use compact fluorescent bulbs.

17.
Dress lightly when it’s hot instead of turning
up
the air conditioning. Or use a fan.
Dress warmly when it’s cold instead of turning
up the heat.
Offer to help your parents keep the air filters on
your AC and furnace clean.
Walk short distances instead of asking for a
ride in the car.
Plant a tree. Recycle.
