Reconstructing past environments from proxy records is an important tool for addressing long-term environmental change. The current global context of increased air and sea temperatures, increases in the frequency and intensity of large-scale natural disasters, and the location of large populations in vulnerable areas highlights the importance of accessing proxy records that extend the baseline of environmental information beyond historical records.
This session will cover a wide range of topics from around the globe that explore the drivers and patterns of climate and environmental change over long and short timescales. Presenters will discuss new records of natural and anthropogenic environmental change in research including, but not limited to: paleoclimatology, paleoecology, paleolimnology, palynology, fire history, climate modelling, geochemistry, and archaeology.
