    • affect on agriculture
      • hotter summers more frequently and less cold winters
      • crops can grow further north because of increased rainfall in the winter

      • types of crops will change
      • increase in crop pests
    • affect on diseases
      • increase in global temperature means that pathogens and carriers will be able to survive in previously colder areas
