  1. when price increase quant decreases. Wheat belt moves north the place where you can grow wheat moves north. Rise in sea level because melting ice caps melting

  2. Effect in general
    -Colder in some countries
    -Hotter in some countries
    -Extreme weather conditions
    -Animals may not be able to adapt

    Food Patterns
    -Because of hotter and drier weather land to grow crops will decrease, therefore prices will rise
    -Area that grows wheat will move further north

    Rising Sea levels
    -Sea levels rise because of melting ice sheets and glaciers (NOT icebergs), seawater expands as it gets hotter
    -e.g. Kiribati islands are completely flooded by sea water

  3. The negative effects that climate change is having on the environment and people

    OVERALL GLOBAL CLIMATE:
    • affect weather and long-term conditions in all parts of the world
    • colder weather
    • changing of food pattern
    • species of animals going extinct
    • more storms and floods in the UK
    • lack of snowfall in the mountains
    • many cities use water from glaciers

    CHANGING PATTERN OF FOOD:
    • crop yields of countries close to the equator will decrease
    • lose almost ⅓ of maize crop
    • if climate change reduces harvests, food prices will rise and populations will be badly affects especially in sub-Saharan Africa.
    • reduce food security
    • 50% decrease in area of land to grow wheat
    • 'wheat belt' moves North
    • forced to consider new crops e.g plantain

    RISING SEA LEVELS:
    • in 20th century, sea level rose by 88cm
    • caused by addition of water from the melting ice and the expansion of the sea water as it gets hotter
    • people are leaving low-lying coral islands before being engulfed by the sea
    • low lying costal lands are at risk of flooding e.g. London, New York, Hong Kong and Tokyo.

    RETREATING/MELTING GLACIERS:
    • caused by increase in temp due to climate change
    • gulf stream will be diverted further south, leading to colder temperatures in western Europe
    • large fraction of glacier is melted away into the sea

    very informative lesson, used a lot of specific data and figures.

  5. Guys here is a great map to show the effects of sea level rise.

  6. Climate Change
    Effect in General
    -colder in some placers
    -hotter in some countries
    extreme weather conditions
    animals may not be able to adapt

    Food Patterns
    -Because of hotter and other drier weather lead to grow crops will decrease therefore prices will rise.
    -Areas that grows wheat will move further north

    Rising Sea Levels
    -Sea levels rise because of melting ice sheets and glaciers, seawater expands as it gets hotter
    -e.g Kirbati

    1/3 reduction on maize
    Decrease in what harvest
    Food prices rise
    Supply vs demand
    Reduce food security. Sub-sharian apricot
    ‘Wheat belt’ moves north

    NOT MELTING ICE BERS

    MELTING ICE SHEETS AND GLACIERS
    THERMAL EXPANSION, WARM WATER TAKES UP MORE SPACE
    COASTAL FLOODING
    MANY CITIES USE WATER FROM GLACIER.

    DON’T SAY MELTING ICEBERG

  7. Rising Sea levels
    When the glacier melts the Sea levels rise seawater expands as it gets hotter

    Chaning patter of food:
    if the climate changes, it reduces harvests, and the food prices will rise and populations will be effective because poor countries cant afford the food.
    Wheat belt moves north
    ⅓ reduction on maize

    Climate change:

    • colder weather/hot weather
    • changing of food pattern
    • species of animals going extinct
    • more storms and floods in the UK
    • lack of snowfall in the mountains
    • many cities use water from glaciers
