Climste Change

Question 1

Human factors contributing to a higher average work temperature

Answer 1

Increasing co2 levels
Enhanced burning of fossil fuels - industry, agriculture, power stations, transport
Deforestation
Increased methane levels
Increasing numbers of flatulent domestic cattle
Paddy fields
Waste disposal sites

Question 2

Physical factors contributing to a higher average work temperature

Answer 2

Sunspot activity - Changing solar radiation outputs serve to raise and lower world temps
Orbital variations - Tilt in the earths axis can cause greater insolation at the poles
Earths orbit around the sun ‘stretches to an elliptical shape, decreasing insolation
Volcanic eruptions - Shield incoming insolation
Increasing methane levels - Peat bags
