A short-rotation coppice in the UK sequesters biomass at the rate of 1 kg/(m² yr²). Calculate the mean cooling over a typical 16-hour day in the summer. How much will the temperature of the surrounding air decrease due to this cooling? You may assume that the cooling affects air up to a height of 10 m and the heat capacity of air is 1 kJ/(kg K). Calculate the carbon sequestered by this coppice using the fact that 2 to 3 x 10^-3 moles of CO₂ are assimilated per mole H₂0 lost.
