•Reduce crop yields in most tropical and sub-tropical regions of the world, where food is most scarce. Meanwhile, increases in summer rainfall may benefit crops and commercial forestry in some areas
•Less availability of water in arid regions, higher risk of flooding from heavier rainfall in temperate regions (Warm air holds more water vapor than cold, evaporation in dry areas and downpours in wet areas increase)
•Rising sea levels could flood/submerge many low-lying areas (Not because of melting of polar ice caps, but thermal expansion of hotter water)
• Will cause aggravated erosion, displacement of people, particularly bad for poorer regions that can't afford to protect themselves.
•Mosquitos would benefit from a wetter world, making diseases such as malaria and dengue fever more common; Likely to affect those who can least afford to pay for their treatment
• Biodiversity could suffer and the earth's capacity to absorb greenhouse gases, as humans cut down more greenery (Coral reefs could be damaged by increase in bleaching events; Asia-Pacific region may lose up to 13% of its mangrove wetlands).
• Increase in extreme weather: tropical cyclones/ typhoons/ hurricanes, storm surges (causing coastal erosion), thunderstorms, hail, tornadoes, heat waves, floods, droughts in specific areas.
