climate change

Question 1

what is the evidence for climate change over the past 2 million years?

Answer 1

plants animals found in places with special adaptations
ice melting
measuring weather and historical records
ice core (where you drill into the ice and analyse its chemistry)

Question 2

what are the natural causes of climate change?

Answer 2

volcanic activity
solar output
milankovitch cycles

Question 3

what are some human causes of climate change?

Answer 3

fossil fuels
agriculture
deforestation

Question 4

what are the greenhouse gases?

Answer 4

methane
water vapour
carbon dioxide

Question 5

what are the positive and negative impacts of climate change on the UK?

Answer 5

positive-
lenght of the growing seaon will increase
plants and shrubs can be grown further north

negative-
many coastal ports will be flooded
greater risk of forest fires
more pests and diseases will exist due to milder weather

Question 6

what are the positive and negative impacts of climate change on the world?

Answer 6

positive-
increased yield due to higher temperatures
crops can be grown further north due to warme weather

negative-
reduced rainfall in rainforests due to deforestation
places become to warm for coniferous forests to grow
increased tropical storm and flood activity

Question 7

what are some ways to mitigate climate change?

Answer 7

alternative energy resources
carbon capture (possible to capture 90% of the CO2 that would otherwise end up in the atmosphere)
planting trees
international climate (2015 paris agreement- keep global temp increase below 2*C)

Question 8

what are some ways of adapting to climate change?

Answer 8

changes in agricultral supplies- desalination of sea water
reduce risk from rising sea levels- build houses on stilt, coastal mangroves restored
managing water supply
