“Warming of the climate system is unequivocal, as
is now evident from observations of increases in
global average air and ocean temperatures,
widespread melting of snow and ice, and rising of
the global mean sea level.” (IPCC, 2007)
The concern is that the climate is changing too
rapidly for natural ecosystem and human
adaptation.

Latest 2009 findings
The Earth is presently tracking towards worst-case
impact scenarios outlined in the 2007 IPCC 4AR
The is growing evidence to suggest that these
scenarios may be overly conservative
If present greenhouse gas emission trends continue
the Pacific region could experience mean sea-level
increases of 1m or more
We are locked into some degree of climate change
regardless what the industrialized nations do now!

• Climate Change Mitigation and Climate Change Adaptation are
complementary risk management strategies
• The UN Framework Convention for Climate Change (UNFCCC) frames
obligations for each country to implement both strategies

Climate Change impacts
Changes in forest
composition,
extent, health &
productivity
PUBLIC
HEALTH
Variability in water supply, quality
and distribution. More competition
and cross-border conflicts over
water resources
AGRICULTURE FORESTRY
Increasing incidents of
infectious, water-borne and
vector-borne diseases, heat
stress & mortality, additional
public health costs
UNDP Environment and Energy Group
WATER
RESOURCES
Erosion,
inundation,
salinisation, stress
on mangroves,
marshes, wetlands
COASTAL
SYSTEMS
Less predictability in crop
yield, changing irrigation
demand, growing risk of pest
infestations
ECOSYSTEM
SERVICES
Loss of habitat,
species and
protective
ecosystems,
migratory shifts

SCOPING STUDY
Given PIC vulnerability we must primarily
focus on adaptation
Strong call from PICs for less consultation
and more delivery of ‘concrete’ adaptation
measures at the community level to provide
case-studies and lessons learnt
A call to focus on adaptation measures that
provide short-term development outcomes and
build long term resilience (e.g. food security
and DRM)

CONTINUED…
Also need to continue focus on mitigation measures
that provide ‘win-win’ outcomes
Short term poverty reduction
Longer term resilience to climate change
Reduced GHG emissions
e.g. renewable energy, sustainable transport,
mangrove planting etc
