Unit 7.3 Mitigation and adaptation

Question 1

Mitigation

Answer 1

attempts to reduce the causes of
climate change

Question 2

Adaptation

Answer 2

attempts to manage the impacts
of climate change.

Question 3

MITIGATION STRATEGIES for Climate Change

Answer 3

1. Reducing the emission of greenhouse gases
2. Enhancing the sinks accumulating and storing these gases (such as the oceans, forests and soil).

Question 4

CASE STUDY: 5 Ideas for Mitigation

Answer 4

1. Reduction of energy consumption
2. Reduction of emissions of N2O
   and CH4 from agriculture
3. Use of alternatives to fossil fuels
4. Remove CO2 from atmosphere
5. Geo-engineering

Question 5

Reduction of energy consumption

Answer 5

1. Reduce energy waste by using it more efficiently
2. Reduce overall demand for energy and electricity by changing lifestyles and business practices
3. Adopt carbon taxes and remove fossil fuel subsidy
4. Set national limits on GHG production and a carbon credit system
5. Personal carbon credits, can be traded and encourage people to
   reduce their carbon footprint

Change priorities in governments (local, regional, national) small to big ideas: Zona de Baixes Emissions (Barcelona)

Question 6

Reduction of emission of N2O and CH4 from agriculture

Answer 6

1. Reduce methane production of cows by changing their diets
2. Capture more methane produced from landfill sites
3. Sustainable agriculture (natural and organic fertilizers)

Question 7

Use of alternatives to fossil fuels

Answer 7

1. Replace high GHG emission energy sources with low GHG emission
   ones, eg. hydroelectric instead of burning fossil fuels.

Question 8

Remove CO2 from atmosphere

Answer 8

Increase the amount of photosynthesis with
1. Reforestation
2. Reduction of deforestation
3. Carbon Capture and Storage (CCS)
- capturing CO2 emissions
before being released into the atmosphere from power stations, oil refineries and other high-emission
industries. Once captured, those CO2
can be stored underground.

Question 9

Geo-engineering

Answer 9

1. Send mirrors into space between the Earth and the Sun to reflect
   solar radiation
2. Release Sulphur dioxide from aeroplanes to dim the incoming sunlight

Question 10

Examples of adaptation strategies

Answer 10

1. Build to resist flooding
2. Cities must be protected against rising ocean levels
3. More widespread vaccination
4. Desalination plants to cope with changes in the supply of water
5. Changing agricultural production
