Understanding Abrupt Climate Change in the Past
Dr Stephen Barker BSc PhD
School of Earth & Ocean Sciences, Cardiff University
We have all seen news reports and even movies about the possibility of abrupt climate change in the future. But where did the idea of abrupt climate change come from and why do we think that Earth's climate can change at all? Here I will introduce some of the evidence that
paleoclimatologists have used to demonstrate the occurrence of abrupt climate change in the past. Climate records from polar ice cores, deep sea sediments and cave stalagmites all provide clues in this story. I will show how these records have contributed to our understanding of the climate system and ultimately how we think that abrupt climate change may have influenced human societies in the past.
