PP22A:
Global Change During the Holocene and Anthropocene: New Methods, Questions, and Perspectives II
Submit an Abstract to this Session
Session ID#: 6816
Session Description:
Long-term records of climate and environmental change are essential to understanding how terrestrial and aquatic ecosystems will respond to ongoing global warming. The purpose of this session is to highlight recent research focused on understanding the patterns and causes of climate and environmental change during the Holocene epoch using traditional or novel methods. We welcome abstracts focused on any geographic region, and using any proxy or combination of proxies. We also solicit studies focused on broad, regional-scale investigations using paleoecological and archaeological databases (e.g., Neotoma, CARD), and climatic or geophysical modeling. Additionally, we welcome papers that consider new insights into the Anthropocene, the period of time characterized by significant human impact on earth’s climate and environment. Humans have played a role in shaping landscapes and environments for thousands of years and studies that examine these questions help place modern environmental-human interactions into a long-term context.
