NATURAL SYSTEM IMPACTS
VEG SHIFT-North-Coniferous forest on Tundra, destabilising food webs.
-Longer, Warmer growing season.
PERMAFROST THAW- 40%, esp. siberia.
-Rising rivers=increased flooding
-Impact Freshwater fish
INCREASED FIRES&INSECTS-Tree death - loss of habitat
UV - Kills phytoplankton
CARBON CYCLE CHANGES-More forests = more primary productivity.
-More CO2 uptake.
-Methane may counterbalance.
OTHER- More coastal erosion as permafrost thaw weakens coast = more storm surges.
WATER ISSUES - Many rivers internationally shared (Nile) ->potential conflict.
-Demand outstrips supply.
FOOD INSECURITY - 70% subsistence farmers.
-Increased locusts -> threaten food.
NATURAL RESOURCES - Poor depend on plants, reduced biodiversity affects them.
HEALTH - Vector&Water-borne diseases increase.
-80% remedies rely on plants.
*Loma Prieta EQ 1989.
*El Nino -> Drought -> LA desert.
*Fog/Smog->suburbanisation - increased vulnerability to wildfires.
*Dry climate=drought-> When it rains, it pours.
*Vulnerable population - 40 million - megacity.
