Managing climate change Flashcards
How Planting trees is a mitigation strategies to try and reduce the causes of climate change
Planting trees increase the amount of carbon dioxide that is absorbed from the atmosphere through photosynthesis.
How Carbon capture is a mitigation strategy to try and reduce the causes of climate change.
1) Carbon capture and storage (CCS) is designed to reduce emissions from power stations burning fossil fuels.
2) CCS involves capturing carbon dioxide and transporting it to safe places where it can be stored, e.g. deep underground
How Alternative energy production is a mitigation strategy to try and reduce the effects of climate change
1) Replacing fossil fuels with nuclear or renewable energy can help reduce greenhouse gas emissions.
2) In the UK, more offshore wind farms are being built, e.g. in East Anglia, and several wave, tidal and nuclear power projects have been planned.
How international agreements is a mitigation strategy to try and reduce the effects of climate change.
1) The Paris Agreement aims to reduce greenhouse gas emissions and limit global warming. It came into force on 4th November 2016 and has been signed by 195 parties, including the European Union (EU). It encourages developed countries to help developing countries put mitigation strategies into place.
2) Each country has submitted a pledge which indicates how much they will try and reduce their greenhouse gas emissions. The UK has pledges to reduce emissions has pledged to reduce emissions by at least 68% from their 1990 levels by 2030 .
How adapting to Changing agricultural systems is important to responding to the effects of climate change.
Changing rainfall patterns and higher temperatures will affect the productivity of existing systems.
1) It may be necessary to plant new crop types that are more suited to the new climate conditions in an area, e.g. soya, peaches and grapes may be grown in Southern England.
2) In some regions, biotechnology is being used to create new crop varieties which are more resistant to extreme weather events, e.g. drought -resistant millet is being grown in Kenya.
How adapting to managing water supply is important to responding to the effects of climate change.
Dry areas are predicted to get drier, leading to more water shortages- so people need to use water resources more efficiently.
1) Water metres can be installed in homes to discourage excessive water use.
2) Rainwater and waste water can be installed in homes to discourage excessive water.
How adapting to coping with rising sea levels is important to responding to the effects of climate change.
Sea levels are predicted to rise between 0.28 m and 1.01 m by 2100- this would flood many islands and coastal areas.
1) Better flood warning systems are being put in place, and physical defences such as flood barriers are being built. E.g. the Thames barrier in London can be closed to prevent sea water flooding the city.
2) In areas that can’t afford expensive flood defences, e.g. Bangladesh, people are building raised flood shelters and building houses on embbankments
