The challenge is to better determine:
1)how the climate system is
changing
2)how the forcings are
changing
3)how these relate to each
other (incl. feedbacks)
4)attribution of anomalies to causes
5)what they
mean for the immediate and more distant future (assessment)
6)Validate
and improve models
7)seamless predictions on
multiple time scales
8)how to use
this information for informed planning and decision making
9)how to
manage the data and reanalyze it routinely
10)how to
disseminate products around
the world
11)how to
interact with users and
stakeholders and add regional value
