the
Third
Assessment
Report
of
the
Intergovernmental
Panel
on
Climate
Change
was
compiled
to
describe
the
current
state
of
understanding
of
the
climate
system
as
it
was
when
the
document
was
written
in
2001.
It
provides
estimates
of
the
climate
system's
projected
future
evolution
and
the
uncertainties
associated
with
these
projections.

A
phase
diagram
shows
the
preferred
physical
states
of
matter
at
different
temperatures
and
pressures.
This
phase
diagram
shows
these
states
for
water.
Critical
points,
triple
points,
and
ice

processes
are
defined
and
illustrated
as
a
function
of
pressure
and
temperature.
The
diagram
is
accompanied
by
a
set
of

In
this
chapter,
users
take
the
role
of
students
from
a
small
town
in
Colorado,
who
team
up
with
students
from
the
town
of
Churchill,
Manitoba,
to
explore
changing
sea
ice
conditions
in
the
Arctic.
Together
they
examine
an
animation
that
shows
30
years
of
satellite
images
to
see
how
the
extent
of
sea
ice
in
the
Arctic
has
diminished
over
time.
The
chapter
storyline
is
built
around
the
real-life
case

In
this
chapter,
using
My
World
GIS,
users
explore
data
that
characterize
the
dynamic
Greenland
Ice
Sheet.
By
examining
photographs,
map
views,
and
tabular
data,
users
gain
an
understanding
of
how
and
why
scientists
are
monitoring
the
ice
sheet
and
what
they
are
finding.
Users
explore
map
layers
that
represent
ice
sheet
thickness,
weather
station
locations,
and
annual
melt
extents
of
the
ice
sheet.

This
lithograph
shows
the
break-off
of
a
large
iceberg
from
the
Pine
Island
Glacier
in
West
Antarctica.
This
event
occurred
between
November
4th
and
12th,
2001,
and
provides
powerful
evidence
of
rapid
changes
underway
in
this
area
of
Antarctica.
The

This
5-minute
animation
portrays
fluctuations
in
the
cryosphere
through
observations
collected
from
a
variety
of

sensors.
The
cryosphere
consists
of
those
parts
of
the
Earth's
surface
where
water
is
found
in
solid
form,
including
areas
of
snow,
sea
ice,
glaciers,
permafrost,
ice
sheets,
and
icebergs.
In
these
regions,
surface
temperatures
remain

This
two-part
activity
provides
information
on
seasonal
changes
in
the
mass
balance
of
the
Antarctic
Ice
Sheet.
In
Part
1,
students
use
an
atlas
and
satellite
imagery
to
examine
the
geography
of
the
region
and
identify
seasonal
changes
in
the
boundaries
of
the
ice
sheet.
In
Part
2,
they
will
collect
a
series
of
images
of
the
Antarctic
ice
sheet
covering
a
period
of
several
years,
draw
the
boundaries

This
series
of
activities
demonstrates
some
effects
of
rising
levels
of
greenhouse
gases
on
climate.
Specifically,
it
shows
how
an
increase
of
heat-trapping
gases
in
the
atmosphere
raises
temperatures;
higher
temperatures
affect
the
water
cycle,
and
rising
sea
levels
could
affect
coastal
areas
as
a
result
of
glacial
and
polar
ice
melt.
Although
these
activities
are
designed
to
teach
specific
skills
