is
greenhouse?DefinitionThe
so-called
greenhouse3effect
is
short-waveradiation
throughsolartheatmosphere
into
the
ground,and
warming
the
groundafter
the
length
of
radiationbeing
released
in
theatmosphere
by
absorbingcarbon
dioxide
and
othersubstances,
thereby
creatingthe
effect
of
atmosphericwarming.Greenhouse
gas:Carbon
dioxide
is
notthe
only
greenhousegas.Other
gases,
such
asmethane
(CH4)
andnitrous
( 氮的、硝的)oxide
(NO),
are
evenstrongerinfrared(紅外線的)absorbers.4The
natural
greenhouse
effect
is
crucial(決定性的)
for
maintaining
the
propertemperature
needed
to
sustain(支持、支撐)life
on
Earth.BUT
:THEGLOBALWARMING!!!5Global
warming6TemperatureA
worldwide
greenhouse
effect
might
produce
adangerously
warmer
world.Since
the
late
19th
century,
the
average
globaltemperature
has
increased
between
0.3°
C
and
0.6
°C.
Internationally,
2010
was
the
hottest
year
onrecord
since
official
weather
records
first
startedbeing
kept
by
the
British
in
about
1860.7Estimates(估計)
of
globalaverage
temperatures
haveprojected
an
increase
of
asmuch
as
5°C
before
the
year2100.
Such
a
rise
in
globaltemperature
would
producenew
patterns
and
extremedrought
and
rainfall,
whichwould
seriously
disrupt
food.
This
couldproductionpotentiallyAmericancorn

the
Northwhichproduces
much
of
the
world'sgrain,
leading
to
much
higherfood
prices,
and
even
less
foodfor
the
Third
World
than
theyalready
have.8The
other
serious
worryis
thatrisingsealevelsfrom
the

countries.
Arise

levels
of

which
manyexperts
are
predicting
bythe
year
2100
(and
someas
soon
as
2030),
wouldflood
15
percent
of
Egypt(埃及),and
12
percentof Bangladesh(
孟加拉國
).The
Maldives (

almost
completelydisappear.返回9What
are
the
factors?
The
mankind
burning
coal,oil,
naturalgas
and
treeand
produce
a
great
deal
of
carbon
dioxide
andmethane
so
many
years,
those
gases
get
into
theatmosphere
make carbon
circulate

and
have
changed

And
finallybecome

候變化框架公約的京都議定書》)是《聯(lián)合國氣候變化框架公約》(United Nations FrameworkConvention on ClimateChange,UNFCCC)的補(bǔ)充條款。是1997年12月在日本京都由聯(lián)合國氣候變化框架公約參加國三次會議制定的。其目標(biāo)是“將大氣中的溫室氣體含量穩(wěn)定在一個適當(dāng)?shù)乃剑M(jìn)而防止劇烈的氣候改變對人類造成傷害”。12AOSIS
