Document Summary
4 ecosystem services: provisioning (water/food supply), supporting (maintaining ecosystem services like nutrient recycling), regulating (maintaining planet processes like climate), and cultural (rec/spiritual) 5 examples of ecosystem service impacts by climate change: Food of marine fisheries are natural/unmanaged ecosystems; catch/population size fluctuates with atmospheric circulation and water temps (eg. >50% of pacific/atlantic fish catch influences by temp) Peruvian anchovy catch increases in cool periods while sardine catch increases in warm periods; eg. in 1960s it was very cold so anchovy catch was high, and in 1980/90s it was warm so sardines were high. Species-dependent fisheries may either have lots of fish or none; eg. collapse of cali sardine fishery where entire processing industry was lost collapse of peruvian anchovy fishery jobs/food was impacted. Increased temp (bc of climate change) causes increased need for water by organisms. Some areas more sensitive than others; eg. mediterranean climates like cali, chile, sw aus, cape of s. africa, etc.
