Greenhouse
Gases
gases
in the
atmosphere
that
trap
some of the
sun's radiation
and
warm
the
Earth
e.g.
carbon dioxide
(
CO2
) ,
methane
(
CH4
) and
nitrous oxide
(
N2O
) and
water vapour
(
H2O
)
greenhouse
Gases
keep the
Earth's
surface warm
enough for
living things
to
survive
(
greenhouse effect
)
enhanced
greenhouse
effect
causes the
average
global
temperature
to
increase
and
global
warming
to occur
warmer
temperatures
over time lead to
climate
change
Human activities that increase production of greenhouse gases
Deforestation
results in
increased
amount of
carbon dioxide
combustion
of
fossil fuels
releases
carbon dioxide
into the
atmosphere
Increased breeding
of
cattle
on
farms
increases
amount of
methane
in the
atmosphere
disposal
of
waste
in
landfills
increases
amount of
methane
in the
atmosphere
Climate
Change
refers to
change
in
weather conditions
over a
period
of
time
due to
humidity
,
temperatures
of
oceans
and
speed
and
direction
of
wind
Effects of climate change include :
too much
or
too little rainfall
heat waves
tropical storms
ocean warming
and
acidification
melting
of
glaciers
and
polar ice caps
