5. Climate Impacts on Agriculture (EPA 2016)
Plants like CO2, but….
Heavy precipitation events damage crops.
Wetter springs delay planting.
Longer, drier summers reduce water availability and increase heat stress.
Warmer spring temperatures followed by cold snaps cause frost damage.
Warmer winters and increase pressure from weeds and pests.
Parts of the NE will become unsuitable for apples, blueberries, etc.
