a. Use the data in Table 2.2 (Block 4 Part 2, p. 98) to calculate the amount of carbon stored within one million square kilometres (M km²) of 'tropical and subtropical forest'. Your answer should be in gigatonnes of carbon per millions of square kilometres (GtC per M km²). Include your working in your answer and give your answer to 3 significant figures. (5 marks) b. Including your working and showing your answers to 3 significant figures, carry out the following calculations. i. Convert your answer to (a) into millions of tonnes of carbon per M km² (MtC per M km²). ii. Now convert your answer from millions of tonnes of carbon per M km² to millions of tonnes of carbon per km² (MtC per km²). (4 marks) c. Monitoring by Brazil's National Space Research Institute shows that deforestation rates continue to rise, with over 40% more deforestation in 2020 compared to 2018. In 2020 the Brazilian Amazon lost 10 851 square kilometres of forest cover as a result of deforestation (INPE, 2021). Use your answer to (b ii) to calculate what the annual loss of carbon from this deforestation was. Include your working, and give your answer in millions of tonnes of carbon (MtC) to 3 significant figures.
