  • Climate Change is the greatest natural hazard we will face.
    • affects on the environment.
      • Increased greenhouse gases.
        • Due to increased temperatures the seas will not be able to hold as much stored CO2 so greenhouse gas levels will increase as well as human production increasing to supply the growing population.
          • 395 parts per million is expected to be reached by 2016 from 318ppm in 1960.
      • eustatic change.
        • An increase in global temperatures will melt frozen ice shelfs and glaciers increasing the global sea levels.
          • If all the Antarctic ice melted sea levels will rise by 7000ft
      • Increased temperature.
        • Due to the insulating layer of greenhouse gases, sun spot solar flares, The Milankovitch cycle and the enhanced green house effect global temperatures will increase.
          • Global temperatures will increase by 6 degrees Celsius by 2100.
        • Due to increased global temperature sea levels will rise increasing the amount of storms and the size of storms.
          • In 2012 there were 10 named hurricanes in america and in 2015 there were 12 named hurricanes.
          • Due to the insulating layer of greenhouse gases, sun spot solar flares, The Milankovitch cycle and the enhanced green house effect global temperatures will increase.
            • Global temperatures will increase by 6 degrees Celsius by 2100.
      • Desertification
        • The extents of desert will expand especially into arable land in northern africa.
          • the Sahara is expanding 30 miles south per annum.
      • loss of habitat.
    • affects upon the economy.
      • Raw materials will be lost.
        • Due to the expansion of deserts and the changes in levels of rain fall raw materials such as trees will diminish in quantity and therefore less profit can be made.
      • primary and secondary goods productions will slow.
        • As raw materials run out production from these materials will also.
      • The development of plastics as we know them will slow.
        • As the levels of oil will decrease the production of plastics will have to change.
          • Oil is part of our lives and climate change will make it difficult to get at this oil due to rougher seas and other factors.
      • Security threats from mass migrations of people.
        • As land becomes uninhabitable large numbers of people will move and have no steady source of income so looting and theft will increase unless migration is planned.
          • Kiribati is already planning to move from its island as seas encroach. which involves moving 102,351 people safely.
      • Property and infrastructure damaged or lost.
        • As sea levels rise property in coastal and low lying areas will be damaged or flooded.
