The
warming
trend
in
the
Arctic
is
almost
____________________
as
large
as
the
global
average
in
recent
decades
.
The
possible
causes
are
:
changes
in
cloud
cover
,
increases
in
atmospheric

more

ice
have
all
been
suggested
as
contributing
factors
.
The
loss
of
sea
ice
is
one
of
the
most
cited
reasons
.
When
reflective
ice
melts
,
a

ocean
dominates
;
this
amplifies
the
warming
trend
because
the
ocean
surface
absorbs

heat
than
the
surface
of
snow
and
ice
.

Other

causes
are

,
which
are
much
less
likely
to
occur
in
the
Arctic
than
in
tropic
regions
.
The
storms
transport
heat
from
the
surface
to
higher
levels
of
the
atmosphere
,
where
global
wind

sweep
it
toward

The
abundance

creates
a

a
process
that
dampens
