Climate change, resulting from both
natural and anthropogenic factors, is
expected to affect virtually every aspect
of marine ecosystem structure
and function from community composition
and biogeochemical cycling,
to the prevalence of diseases. Climate
can affect all life-history stages
through direct and indirect processes
and the possible effects of climate
change for marine populations include
changes in population dynamics
(body size, reproduction), community
composition and geographical
distributions.

The Pacific Islands region is experiencing climate change. Key indicators of the changing
climate include rising carbon dioxide in the atmosphere, rising air and sea temperatures,
rising sea levels and upper-ocean heat content, changing ocean chemistry and increasing
ocean acidity, changing rainfall patterns, decreasing base flow in streams, changing
wind and wave patterns, changing extremes, and changing habitats and species distributions.
Currently, the most vulnerable areas include low islands (atoll islands and other

Erosion is the process where soft shorelines (sand, gravel
or cobble) disappear and land is lost. Erosion generally
comes in two forms; 1) A natural part of the coastal environment
where a soft shore moves and changes in response to
cyclic climatic conditions, and 2) Erosion can be induced by
human interference of natural sand movement and budget
patterns. Erosion can be slow and ongoing over many
years or fast and dramatic following large storm events.
Many erosion problems in the Pacific today, occur because
