Regional
global warming ‘hotspots’, typified by above average ocean temperature
increases, provide the potential for early warning and evidence
of the response by natural resources to climate change. In theory,
regions at the ‘front-line’ of climate change should also be
leading the field in terms of assessing impacts and evaluating
adaptation options. Networking and synthesising outcomes from
across hotspots can facilitate accelerated learning and also
indicate sensible pathways for maximising adaptation and minimising
impacts for other global regions.
This workshop is
designed to (1) highlight where global marine ‘hotspots’ occur
now, and where they are projected to occur in the future; (2)
summarize the information currently emerging on biological climate
change impacts in these areas, and (3) discuss the potential
for developing a global network of scientists, policy makers
and managers working in marine hotspots.
Ecological monitoring
of hotspots provides us with one of the first opportunities
to detect the nature and pace of climate change induced impacts
on our marine ecosystems, and also the first prospect for validating
species or ecosystem model projections against reality. Fisheries
provide significant social and economic benefits globally, and
early warning of changes in resource quality and/or availability
is required to minimize social tensions (e.g.,
increased poverty and changes in resource allocation) and societal
costs (e.g., income redistribution
and government restructuring). Prior knowledge of how and when
resources may alter will also facilitate the development, application
and evaluation of adaptation options for fisheries.
Participants providing
or presenting a summary of impacts from any of the global hotspots
will be asked to contribute to a multi-authored publication
in a high-ranking international journal. Identification of biological
change in these hotspots is the main workshop challenge; however,
participants are also requested to identify publications or
unpublished data showing long-term change in oceanographic or
physical characteristics of the area (e.g.,
SST, currents). Several potential proposals and funding sources
for a global network of marine hotspots will be discussed.
