Climate Change

Question 1

natural causes of climate change

Answer 1

• orbital changes
• solar output
• volcanic activity

Question 2

human causes of climate change

Answer 2

• fossil fuels burning
• deforestation
• agriculture

Question 3

what evidence is there of climate change from the quaternary period

Answer 3

• ice cores
• ocean sediment
• studying tree rings
• pollen
• art and literature

Question 4

How does agriculture increase rate of climate change

Answer 4

• demand for meat and rice

- accounts for 20% of greenhouse gas emission

Question 5

How does volcanic activity affect rate of climate change

Answer 5

cools the earth

ash clouds and volcanic aerosols reflect the sunlight away

Question 6

How do orbital changes affect climate change

Answer 6

elliptical orbit
earth tilted on its axis
earth isn’t shperical

Question 7

How does solar output affect climate change

Answer 7

solar output barely affects climate change but it has slightly decreased
- also sunspots

Question 8

effects of climate change on people

Answer 8

• increased risk of skin cancer and heatstroke as temps rise
• flood risk increasing insurance and repair costs
• extreme weather increases investment in MPPP
• winter related deaths decrease with milder winters

Question 9

effects of climate change on the environment

Answer 9

• as ice melts, polar wildlife declines
• coral bleaching
• more forest fires
• warmer rivers affecting marine wildlife
• sea level rise increasing flooding and coastal erosion

Question 10

how can mitigation be used to manage climate change

Answer 10

• alternative energy production
• carbon capture
• planting trees
• international agreements

Question 11

how can adaptation be used to manage climate change

Answer 11

• changes in agricultural systems
• managing water supplies
• reducing risk

Question 12

how can changing agricultural systems help when used to manage climate change

Answer 12

• move location to suit climates
• increased irrigation
• changes to type and variety of crop

Question 13

what is carbon capture

Answer 13

when the CO2 is taken from the air and trapped in an impermeable rock

Question 14

what does reducing risk from rising sea levels involve

Answer 14

• constructing defences (Thames barrier or mangrove forests)
• raising properties on stilts
• relocating people at risk

Question 15

what does managing water supplies involve

Answer 15

• reducing demand (installing water efficient devices

- increasing supply (desalination plants
