More specifically, costs and the constraints of
financial resources could pose a great challenge to
adaptation action. Existing studies on adaptation
costs provide only a wide range of estimates and
have many information gaps. Much more knowledge
is required regarding the impacts of climate change
and how they interact, and regarding information on
relevant adaptation options. Although not specific
to transport or ports, a study produced by the world
Bank estimates that, for developing countries, the
cost of adapting to an increase in temperature by
approximately 2° C by 2050 would be, for the period
2010-2050, in the range of $75 billion-$100 billion
