Human - Causes of Climate Change (Human)

Question 1

Increase in fossil fuel consumption

Answer 1

• Factories, power stations, more cars = brining of carbon based fuels e.g. coal, oil and natural gas
• Release CO2 into atmosphere - increases ‘greenhouse gas effect’ - temperatures rise

Question 2

Deforestation

Answer 2

• CO2 released when trees are burned

- Less absorption of CO2 - fewer trees to absorb the gas - leads to a build up in the atmosphere

Question 3

Methane - Cows

Answer 3

• Grassy diets and multiple stomachs release methane - exhale with every breathe
• Many cows herds are bred for human consumption - huge amounts of methane in the atmosphere
• leads to a warmer climate as methane traps in heat

Question 4

Wars (bombs, atomic testing)

Answer 4

• large amounts of dust released into atmosphere

- effects the climate as dust can reduce the insolation received at the earth’s reducing temperatures

Question 5

Aerosols, fridges and air conditioning units

Answer 5

• release green house gases - Chlorofluorocarbons into atmosphere
• causes temperatures to rise and affecting the global climate
