Climate change // mitigation and adaption

Question 1

What does mitigation involve?

Answer 1

it is anthropogenic intervention to reduce the anthropogenic forcing of the climate system

Question 2

Precautions of climate change can be divided into three categories

Answer 2

• international commitments
• national actions
• personal lifestyle changes

Question 3

mitigation strategies // stabilise or reduce GHGs // reduction of energy consumption

Answer 3

• reduce energy waste by using it more efficiently eg. insulation
• reduce overall demand for energy eg. eat less meat, use public transport
• adopt carbon taxes
• set national limits on GHG production
• change government priorities eg. London has toll charge for cars driving into city

Question 4

mitigation strategies // stabilise or reduce GHGs // reduction of emissions of nitrous oxides + methane from agriculture

Answer 4

• reduce methane production eg. change cows diets to produce less methane
• capture more methane produced from landfill sites
• sustainable agriculture

Question 5

mitigation strategies // stabilise or reduce GHGs // use of alternatives to fossil fuels

Answer 5

nuclear power

renewable energy sources

Question 6

mitigation strategies // remove carbon dioxide from atmosphere // increase amount of photosynthesis

Answer 6

• afforestation
• reduce deforested areas
• restore grassland

Question 7

mitigation strategies // remove carbon dioxide from atmosphere // geo-engineering

Answer 7

• scatter iron, nitrates or phosphates on oceans to increase algal blooms which take up more carbon + act as carbon sink
• release sulphur dioxide from airplanes to increase global dimming
• build w light colour roofs to increase albedo + reflect more sunlight

Question 8

adaptation strategies // change agricultural production

Answer 8

• irrigate more effectively in drought areas
• store rainwater for times of shortage
• breed tolerant crops
• grow different crops

Question 9

adaptation strategies // manage the weather

Answer 9

• seed clouds to encourage rainfall

- plant trees to encourage more rainfall
