# Rates of Human Induced Warming

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?
