Mathematical models and
statistical arguments play a
central role in the assessment of the changes that are observed in
Earth's
climate system. While much of the discussion of climate change is
focused on
large-scale computational models, the theory of dynamical systems
provides the
language to distinguish natural variability from change. In this talk I will
discuss some problems of
current interest in climate science and indicate how, as
mathematicians, we can
find inspiration for new applications.
