The bands in the coral’s shell can change in thickness with changes in temperature, water clarity, or nutrient availability, so while each band can record the season’s climate, the interpretation of the record depends on how the three factors are related.Coral paleoclimatology is the use of geochemical records from the skeletons of fossil or modern corals to reconstruct tropical climate variability during the time the coral lived. Introduction Ocean–atmosphere interactions in the tropics have far-reaching consequences for climate variability across the globe. Small, daily actions can help reduce coral reef loss, like reducing stormwater and fertilizer runoff or avoiding herbicides and pesticides.
