Interlinks Between The Cycles Flashcards
Give basic interrelationships between the two cycles
Photosynthesis
Both greenhouse gases
Water absorbs carbon dioxide
Plant life made of carbon, responsible for evapotranspiration
Give two feedback cycles that start form the same effect but cancel each other
Temperature rises Evaporation increases Amount of water vapour increases Enhanced greenhouse effect But Temperature rises More evaporation More clouds Global cooling
Describe how plant life both increaes and decreases global CO2 emmisions with positive and negative feedback
Higher temperature
More plant growth
More respiration so more CO2 therefore positive feedback
But more photosynthesis therefore negative feedback
Give some impacts of climate change
Precipitation effected = more flooding, but more draughts elsewhere
More extreme weather events e.g. Tropical storms
Food shortages
Sea level rise
Reduced biodiveristy
Describe individual climate change mitogation techniques
Imorove home efficiency e.g. bedZed
Less car usage
Describe methods of modifying deforestation to mitigate climate change
Forestry stewardship council- only buy sustainable wood
Selective logging
Protected status - e.g. In brazil
Describe the action of the paris agreement
195 countries signed a climate deal
Limit global temperatures to a 1.5 degree rise on pre industrial level
Increase global education
Help developing nations become more sustainable
Describe carbon capture, give a fact about the boundry dam canada and say why carbin capture is limited
Piping carbon dioxide into ground
Boundary dam in cananda aims to cut emmisions by 90% (equivalent of 250,000 cars)
But schemes are often only economically viable if the carbon dioxide is used to force more fossil fuels out of the ground?
