What is the natural green house effect 
The greenhouse effect keeps the Earth naturally warm enough to support life
What is the difference between enhanced greenhouse effect and natural greenhouse effect 
The enhanced greenhouse effect is due to human activities which has increased the amounts of greenhouse gases but the natural,greenhouse effect keeps the earth naturally warm
How much carbon dioxide accounts for the enhanced green house effect
60%
Where does carbon dioxide get released
Car exhausts
Deforestation
Burning wood
Burning fossil fuels
How much methane accounts for the enhanced greenhouse effect 
20%
How is methane released?
Farm livestock
Rice farming
Burning biomass for energy
Decaying organic matter in landfill sites and compost sites
How effective is nitrous oxide in capturing heat then co2
Very small concentrations are up to 300times more effective
How does nitrous oxide get released
Car exhausts
Sewage treatment
Agricultural fertilisers
Power stations
What are the 4ways climate change can be managed
Alternative energy sources
Carbon capture and storage
Planting trees
International agreements
The burning of fossil fuels accounts for how much of the carbon dioxide emissions
87%
What are the alternative energy sources
Wind, water, geothermal, nuclear, biomass, solar, tides
Explain the process of carbon capture and storage
The process of 'carbon capture and storage' is when carbon molecules are captured, compressed, piped and injected as a liquid to a well underground to be stored in a suitable geological reservoir
How do trees remove Co2 from the atmosphere 
photosynthesis
How does planting trees reduce climate change? 
Trees release moisture into the atmosphere which produces more cloud, reducing solar radiation producing a cooling effect
Trees also absorb Co2
Second international agreement
Copenhagen accord(2009)
Consider International agreements on tackling climate change post 2012
No legally binding agreement -agreed to reduce emissions with financial support for developing nations
Third International agreement 
Paris agreement (2015)
How many countries signed the Paris agreement and why was this agreement more successful then the others
195 countries
The first ever legally binding global climate deal
What were the aims of the Paris agreement
-peak greenhouse gases asap
-balance sources and sinks
-keep global temps below 2c
Review progress every 5years
-100billion dollars a year to support developing countries by 2020
How many countries agreed to sign the Kyoto protocol
170 countries
how can farmers adapt to climate change
-introduce drought resistant crops
-educate farmers in water harvesting techniques
-new cropping patterns
-new irrigation systems
-plant trees to shade seedlings
How can we defend against high sea levels
-construction of sea walls
-build houses raised off the ground on stilts
-construction of artificial islands so people can be relocated
what are the risk of rising sea levels
-important agricultural land such as India and Vietnam are at risk
-contaminate freshwater supplies with saltwater
-increase rate of coastal erosion and damages from storm surges
example of a place at risk of rising sea levels
Maldives is expected to be uninhabitable by 2030 and submerged by 2070
Explain the enhanced greenhouse effect  
More greenhouse gases are emitted such as CO2, methane and nitrous oxide
Leading to and increase in the 'insulating layer' around the Earth
Resulting in the sun's radiation being trapped within the Earth's atmosphere which causes a rise in temperatures
Why do some countries choose to adapt to climate change rather then tackle the issue?  
Because climate change will affect developing nations the most so protecting the people by making them less vulnerable to the impacts of climate change would be cheaper.
For example farmers in places such as Gambia, plant shade trees to protect seedlings from strong sunshine rather than stopping the reason why the sunshine is so strong, which is the release of greenhouse gases from car exhausts, burning fossil fuels etc.
