The natural variability of the global climate system on human-timescales is of great interest to many areas around the world with growing populations that are at risk of either water shortages or flooding. My research uses speleothem archives to construct records of rainfall changes at annual to decadal scale resolution, which capture the magnitude and duration of changes well beyond the scope of the last 30-100 years of observations. The DTP student is focusing his investigation on a controversial centennial scale climate event that occurred ≈4200 years ago, when the background climate state was similar to modern conditions. The student will use multiple geochemical analysis techniques to create high-resolution rainfall records at key locations around the globe which are under-sampled but capable of recording signals from known modern annual to decadal-scale climate oscillations. The student will work with an international climate-modelling group to transform the geochemical records into large-scale atmosphere circulation interpretations, to ultimately determine the mechanisms capable of causing natural changes to the global climate system ≈4200 years ago, and the project results’ relevance to today’s climate projections.
