(a) Assuming the difference between the global average temperature and the benchmark is a linear function of time, find a formula for this function. The increase in average global temperature, G, above the benchmark average in the year t is given by G = i +( i eTextbook and Media (b) Use this formula to predict the difference in 2027. °C The formula predicts that in the year 2027, the average global temperature will have increased by i
