Water Supply & availability Significant decreases in decreases in many regions. water availability.

Falling rainfall in some regions Total collapse of many inland freshwaters Moderate to significant decreases in rainfall in many dry regions. Desertification increases & accelerates.

Declining water quality in many regions. ______________________________________________________________________________________________________

Food Falling crop yields in Falling yields in many regions, 15-40% some areas reduction in global crop production.

Total collapse of many dryer crop regions. Krill decreases Ocean health in moderate decline with

(ocean food chain). significant loss of sensitive ecosystems, & sudden loss of parts of the ocean food chain.

Increasing food shortages & famine. Widespread famine in many regions. Ocean health & food chain irreversibly affected.

_______________________________________________________________________________________________________ Human Rapid spread in diseases like malaria Health Increasing spread of water-borne diseases

Increased respiratory & cardiac difficulties Increasing malnutrition in many regions.

& Species Profound impacts on polar ecosystems & species Sudden extinction of many alpine & marine species/ecosystems Many coastal ecosystems become too saline. _______________________________________________________________________________________________________ Source: Climate Change in the City of Port Phillip – An Initial Perspective
