Water,carbon,climate and life on Earth Flashcards
Give a fact for the importance of water and carbon in the human body as elements
Both are 1 of 6 crucially important elements in humans
What % of the human body is carbon ?
18
Give the water and carbon cycle linked feedback loop
NEGATIVE FEEDBACK
- Increased CO2 emissions in atmosphere
- Increase in global temperatures due to enhanced greenhouse effect
- Increase in phytoplankton in the oceans
- Increase in DMS production
- Increase in cloud formation
- GLOBAL COOLING
What happens as a result of a positive feedback water cycle loop ?
Destabilises the jet stream causing more extreme weather events and variations in global precipitation patterns
What % could CCS cut global carbon emissions by ?
19
What is a type of farming which is carbon conscious to replace a crop with a greater productivity crop to sequester more CO2 ?
Carbon farming
What organisation ensures timber is produced sustainably as a human intervention to influence carbon transfers ?
Forestry Stewardship council (FSC)
Give statistic for protection of Mangroves as a policy to influence carbon transfers
In 2015 Sri Lanka became first nation to protect all its mangrove forests
Give the governmental policy in Brazil to influence carbon transfers ? was it successful ?
Landowners forces to preserve 80% of their forests
- By 2009 rate of deforestation fell by 75% compared with 2004 (however not maintained following new leadership)
When was the Paris agreement and how many countries were involved ?
2015, 195 countries adopted the first universally legally binding global climate deal
Give a feature of the Paris agreement
Limit average global temperature increase to 1.5 degrees C above pre-industrial levels
Give some examples of human interventions in the carbon cycle
- Modification of industrial combustion
- Modification of photosynthesis
- Modification of land use change
- Modification of deforestation
- Policies
