One predicted cоnsequence оf glоbаl climаte chаnge from increased CO2 in the atmosphere is the desertification (land becoming desert) of large areas of the African continent. Desertification may result in fine particles from the iron-rich soils of these areas blowing into ocean areas that currently have low productivity. What effect do you think these events might have on ocean productivity? Why would this happen? What impact might this have on atmospheric CO2 levels? Explain.
