Natural
indicators
of
climate
change,
such
as
melting
glaciers,
changes
in
time
of
flowering
of
trees
in
spring,
and
bird
migrations
are
excellent
indicators
of
long-term
changes
in
climate.
The
behavior
of
animals
and
the
characteristics
of
plants
can
be
biological
proxies
for
long-term
scientific
measurements.
They
are
an
accumulated
response
to
long-term
shifts
in
the
surroundings,
and

This
site
provides
a
brief
overview
of
processes
and
properties
associated
with
global
climate
change
and
its
rate
of
change,
which
is
of
current
concern
to
scientists.
The
carbon
cycle
is
discussed
including
its
sources,
sinks,
and
release
agents
along
with
the
fact
that
it
is
critical
to
the
biosphere
and
must
continue
cycling
to
support
life
on
Earth.

the

that
surrounds
our

This
resource
provides
an
overview
of
the
concept
of
global
warming,
which
is
thought
to
be
due
to
man-made
emissions
of
greenhouse
gases,
which
are
largely
a
result
of
the
burning
of
fossil
fuels
and
deforestation.
It
explores
the
possibility
that
the
impacts
of
global
warming
may
include
desertification
and
the
destruction
of
other
ecosystems,
extreme
weather
conditions,
and
a
danger
to
agriculture.
