  • Climate change.
    • It needs solving.
      • Changes in the wind systems of the earth.
        • Fresh water run-off will cause disruption to the gulf stream.
          • Less warm water drawn north and sea temperature will drop.
      • Permafrost thawing.
        • permafrost will thaw due to the rising temperatures.
          • This will release trapped methane, drain lakes and rivers that are on frozen ground and impact fish species due to the cold water.
            • Up to 40% of the permafrost is expected to thaw across Russia.
      • Loses of habitat for nature.
        • Desertification will expand desterts and lose the population arable farmland as well as
        • fresh water marshes will become salt water.
        • 60% of the great barrier reef will be lost by a 1 degree change in sea temperature.
      • Marine species will be lost.
        • Temperature changes in the sea as well as changes of salinity will hugely affect fish species as the absorption of oxygen will change.
          • 1,851 species of fish were deemed at risk of extinction by the IUCN in 2010.
          • a third of the species at risk are the larger fish such as sharks and rays.
      • migration patterns will shift.
        • land animals such as deer will have to change their migration routes which may put them under threat from straying into built up areas which could result in deaths as they become considered pests.
      • water shortages.
        • Countries such as landlocked Chad will have a diminishing supply of freshwater.
          • 25% of Africans will be outstriped of supply as demand for water increases
      • spread of disease
        • Disease will spread faster as temperatures increase and people move closer together due to sea level change.
          • Eustatic change.
            • Changes in sea levels will cause increased flooding and increased coastal erosion.
            • changes in sea level is hard to predict but all data points to a rise.
          • Diseases such as malaria and cholera and other water or air born diseases will spread.
          • 80% of the health services will rely on plant made remedies whicxh are under threat from climate change
      • Eustatic change.
        • Changes in sea levels will cause increased flooding and increased coastal erosion.
        • changes in sea level is hard to predict but all data points to a rise.
    • Doesn't need solving.
      • Cycles of the earth.
        • Temperature of the earth has fluctuated over the lasted 200 years.
          • Temperatures and CO2 levels have always fluctuated shown by the medieval warm period and the
        • Milankovitch cycles has led to changes in the levels of sunlight entering the earth's atmosphere.
          • distance from the sun has also changed which will affect the temperatures of the earth.
      • not a great deal of people impacted imeadiatly
        • The effects of climate change will not be seen imeadiatley so they can carry on
      • Nature will adapt to the changes.
        • Migration paths and routes will change as nature adapt quicker than humans do.
          • Animals do not have physical attachments such as homes so they can move much more easily
      • It will be expensive to correct time consuming and will mean large changes to big business
        • large companies such as oil companies will have to spend more on clearing up pollution which will lower profits.
