Note: Without natural greenhouse effect mean temperature would be around -18ºC

“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.
Climatic variations Time
Predicted regional changes by 2100 • Air temps 1.0 - 4.17ºC in the N. Pacific • Air temps up 0.99 - 3.11ºC in the S. Pacific • Sea temps up 1.0 - 3.0ºC • Ocean pH by 0.3 - 0.4 units • Sea-level rise of 0.19 - 0.58 m • Rainfall -2.7% to +25.8% in the N. Pacific • Rainfall -14% to +14.6% in the S. Pacific • Possible increased frequency and/or intensity of extreme weather events including cyclones
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! - Copenhagen Climate Change Council, April 2009 -
Climate Change MitigationandClimate Change Adaptation are • complementary risk management strategies • The UN Framework Convention for Climate Change (UNFCCC) frames • obligations for each country to implement both strategies Global Climate Change MITIGATION ADAPTATION Greenhouse gas emissions Climate change impacts • Reduce magnitude of global warming • Reduce greenhouse gas emissions • Reduce vulnerability to CC impacts • Reduce human and material losses
Variability in water supply, quality and distribution. More competition and cross-border conflicts over water resources Erosion, inundation, salinisation, stress on mangroves, marshes, wetlands Changes in forest composition, extent, health & productivity COASTAL SYSTEMS WATER RESOURCES ECOSYSTEM SERVICES PUBLIC HEALTH FORESTRY AGRICULTURE Less predictability in crop yield, changing irrigation demand, growing risk of pest infestations Increasing incidents of infectious, water-borne and vector-borne diseases, heat stress & mortality, additional public health costs Loss of habitat, species and protective ecosystems, migratory shifts Climate Change impacts
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
