(> extreme weather conditions, increased temp)

> temp, < crop yields, < global food supply, food shortage >

mid-latitude plants benefit from warming; longer growing seasons, > precipitation, < frost -> > crop yields >

low-latitude plants @ max temp tolerance, slight temp changes < water availability, disrupt plant growth&development -> < crop yields >

sea level rises, soil erosion submerges shorelines, causes saltwater intrusion -> < arable land -> < food crop production >

migration of weeds/fungi/insects->temperate regions causes > pests,diseases damaging crops & yield >

heat waves,droughts causes heat stress in crops, limits yields. prolonged period of low water availability disrupts germination,fruit development >

high precipitation in sub/tropical regions cause flooding -> loss+destruction of food crops, soil erosion causing poor soil quality
