Climate
change
is
a
broad
term
used
to
refer
to
changes
in
the
Earth’s
climates,
at
local,
regional,
or
global
scales,
and
can
also
refer
to
the
effects
of
these
changes.
In
recent
decades,
the
term
‘climate
change’
is
most
often
used
to
describe
changes
in
the
Earth’s
climate
driven
primarily
by
human
activity
since
the
pre-Industrial
period
(c.
1850
onwards),
particularly
the
burning
of
fossil
fuels
and
removal
of
forests,
resulting
in
a
relatively
rapid
increase
in
carbon
dioxide
concentration
in
the
Earth’s
atmosphere.

Global
warming
is
a
term
often
used
interchangeably
with
climate
change,
as
it
is
one
of
the
most
important
measures
of
global
changes.
Global
warming
refers
to
the
rise
in
average
global
temperatures,
which
is
linked
to
significant
impacts
on
humans,
wildlife,
and
ecosystems
around
the
world.
Because
there
are
more
factors
and
impacts
than
only
rising
surface
temperatures,
the
term
climate
change
is
used
to
include
these
additional
impacts.
There
is
strong
consensus
among
scientists,
representing
97%
of
actively
publishing
climate
scientists,
that
human
influence
has
been
the
dominant
cause
of
observed
warming
trends
since
the
20th
century.

The
concentration
of
carbon
dioxide
in
the
atmosphere
has
risen
from
hovering
around
280
parts
per
million
(ppm)
in
pre-Industrial
time,
to
413
ppm
as
of
early
2020.

This
concentration
of
carbon
dioxide
is
unprecedented
in
recorded
history.
Scientists
have
reported
that
we
need
to
return
to
a
‘safe’
concentration
of
350
ppm
by
2100
in
order
to
stabilize
global
warming.
