The graph below shows how temperature has varied with time. The grey line shows monthly temperatures and the orange line shows an estimate of the contribution of human-induced warming to those temperatures over the same period.
a) Describe the difference between the lines showing monthly temperatures and human-
induced warming.
[2 marks]
b) In what year did human-induced warming reach 0.5K (°C)?
[1 mark]
c) Use the graph to estimate the rate of change of human-induced warming in the year
1970.
[3 marks]
d) Use the graph to estimate the rate of change of human-induced warming in the year
2000.
[3 marks]
e) What does the difference between the rate in 1970 and the rate in 2000 tell us about
how human-induced warming is changing?
