Over the years, a number of abrupt climatic changes have been seen. This study focuses on the most recent, i.e. the post-glacial period that happened between 8,000 and 17,000 years ago.

Evidence of these climatic changes can be found within peat bogs and lake sediments. In this study, cores from Llyn Llech Owain and Carmel bog in Carmarthenshire are used. Proxy techniques will be used to study these changes, including diatoms, XRF and %C as well as tephrachronology and radiocarbon dating of sediments. The project’s aim is to improve our understanding of past climate change by asking a series of questions e.g. what motivated the change? How did the change happen so quickly? And how does the environment respond to these changes (in order to determine whether such changes are likely in future)?
