CARBON!! - Coggle Diagram

- - - - The impacts of cold conditions on carbon stores and transfers:
        
        Chemical weathering processes would have been more active because cold water can hold more carbon dioxide.
        
        Forest coverage would be very different both in total area and in geographical location. This would have affected the significance and distribution of processes such as photosynthesis and respiration.
        
        Decomposers would have been less effective, so carbon transfer to soils would have been reduced.
        
        Less water would have flowed into the oceans as it was locked up as snow and ice on land. There would be less sediment transfer along rivers and les build-up of sediments on the ocean floor.
        
        The soil would have been frozen over vast areas of land. This would have stopped transfers of carbon.
      - The impacts of warm conditions on carbon stores and transfers:
        -In recent years global temperatures have risen and this has been particularly noticeable in the high latitudes. One of the effects of this has been the melting of the permafrost in tundra regions, for example Siberia in Russia.
        
        Carbon stored within the permafrost- together with other gases such as methane- is now being released into the atmosphere where it further enhances the greenhouse effect, leading to increased warming. This is an example of a positive feedback leading to further destabilisation of the system.
