you should
care
This
module
is
essential
because it
helps us grasp

one of today most critical global issues
-
Climate Change
With
better understanding of where greenhouse gasses come from and how they effect the world
, you
better prepared
to make
smart choices
about your own
carbon footprint
and promote more
eco-friendly practices
in your
communities
By learning how to measure and reduce individual carbon footprint
, you can guide
both individual and organizations
to
cut down carbon emissions
This module
will also
discuss worldwide efforts
to
combat climate change
, including
agreements
like the
Kyoto Protocol
. By understanding the
background
and
importance
of these
agreements
, you be
more ready to engage with
and
support climate action
at
local
,
national
and
international level
Gaia
learns
about
carbon footprint
Gaia learns about
carbon footprint
, the
greenhouse effect
, and
role of carbon emission
in
causing climate change
She is
outraged
to
learn that fossil fuels companies
are
recording massive profits
while she now has to
pay 20% more for everything
Learning Point 1: Greenhouse Gasses & Carbon Emissions
Greenhouse Effect
The
greenhouse effect
is
natural process
. It happens when
certain gasses in our atmosphere
, like
carbon dioxide
,
methane
, and
water vapor
,
traps heat
from the
sun
These
gasses
act like
blanket
around
Earth
, keeping it warm. Without these
natural greenhouse effect
, our
planet
would be
incredibly cold
, around
-18 Celcius (0 Fahrenheit)
, which
makes
it
hard for most living things to survive
.
Human-enhanced greenhouse effect function
The enhanced greenhouse effect
, driven by
human activities
, has
resulted
in
higher level of greenhouse gasses
in the
atmosphere
This in turns, has caused a
rise in global temperatures
These
elevated temperatures
are
causing shifts
in
weather patterns
,
higher sea levels
,
melting of polar ice caps
, and
various other effects
on the
Earths eco system
and
human activities
For these reasons
, its the
utmost importance
that we
take steps
to
decrease greenhouse gas emissions
Doing so
, will
helps us reduce the harmful consequences of climate change
and
safeguard the habitability of our planet
Natural
Some
of the
energy bounces back
into
space
,
but
alot of it gets
soaked up by Earth surface
Later, the
Earths surface
send this
energy back
into the
atmosphere
as
infrared radiation
Energy
from the
sun
, which
includes visible & invisible radiation
, enter our
earth atmosphere
However
,
certain gasses
in our
atmosphere
, called
greenhouse gasses
,
capture
some of this
infrared radiation
. Instead of letting the
heat escape into space
, they
hold onto it
This process warms up
the
Earth surface
and the
lower part
of the
atmosphere
, creating the
climate system
we know
worldwide
Kyoto Protocol (LP 1)
The Kyoto Protocol
is a
global agreement
that was
established in 1997
to
tackle issues
of
climate change
by
decreasing
the
release of greenhouse gasses
.
These gasses
were
precisely outlined
in the
Protocol
Under these treaty
,
industrialized nations
were
obligated
to
lower their emissions
of
different greenhouse gasses
to a
level below
what
they were in 1990
by the
year 2012
The Kyoto Protocol
marked
a significant move
in the
direction of alleviating
the
harmful effects of climate change
. It
remains influential
in
present day international discussions
and
agreements
concerning the
climate
Learning Point 2: Main sources of Greenhouse Gasses
Greenhouse Gasses
Greenhouse Gasses
are
gasses
in the
Earth atmosphere
that
trap heat
, making our
planet warmer
. The
primary greenhouse gasses
are
Methane
is
produced
from
various sources
, both
natural
and
human made
, including
farming (like raising livestock and growing rice)
,
extracting fossil fuels
, and
managing landfills
While it has a
shorter atmospheric lifetime
of
12 years
, it has a
stronger warming effect
Nitrous oxide
mainly comes from
activities
in
agriculture
and
industry
, such as
using nitrogen fertilizers
,
taking care of livestock
, and
burning fossil fuels
A
powerful greenhouse gasses
with
long atmospheric lifetime
of about
114 years
Carbon dioxide
mostly comes from
burning fossil fuels
like
coal
,
oil
, and
natural gas
it has a long
atmospheric lifetime
and
contributes
about
70%
of the
total warming
Human Activities
such
deforestation
,
land use change
,
urbanization
and
waste production
contribute significantly to the
increase of greenhouse gas emissions
,
leading to accelerated global warming
Learning Point 3: Individual Carbon Footprints
Global Carbon Footprints
Understanding Global Warming
looking at
carbon footprints
.
A carbon footprint
is the
total greenhouse gasses
we release
through our actions
.
The world entire pupulation
measures the
global carbon footprint
, while
national carbon footprints
are
measured per country
Individual Carbon Footprint
Personal Carbon Footprint
involves
emissions
from
various sources
in our
daily lives
. like your
community service
, the
food you consume
, the
clothes
you
purchase
, the
email piling in your inbox
, the
website you browse
and
much more
Primary Footprints
The
primary footprints
are
greenhouse gasses
that
directly
comes from you, like
electricity, heating & air conditioning
Secondary Footprints
The
secondary footprints
are the
greenhouse gasses
releases
indirectly
through the
product you use
Reducing
our
carbon footprints
is
essential
for a
sustainable world
. It does not happen overnight, but
making small changes
like
eating less meat
, using
public transport
,
cutting down on energy use
, and
spending less time online
can
collectively make a significant effect
