A role for the Indo-Pacific Warm Pool in global climate change
Session ID#: 79811
Session Description:
The Indo-Pacific Warm Pool (IPWP) is a dominant source of heat and water vapor to the atmosphere and influences tropical and global climate dynamics. Traditionally, Neogene climate variability, ranging from long-term trends, to glacial-interglacial and millennial-scale cycles has largely been attributed to forcing from high latitudes or linked to oceanographic processes in the wider tropical Pacific. Recent research, however, suggests the role of the IPWP is underestimated in past and future global climate change. This session will further elucidate this role by exploring changes in the paleoclimate and paleoceanography of the IPWP and surrounding landmasses from the Neogene to Present. We encourage contributions that focus on high latitude - IPWP connections, feedbacks between IPWP hydroclimate, tectonics, weathering and the global carbon cycle during the Cenozoic, and the potential for this region to supply micronutrients to high-nutrient low-chlorophyll areas. Multiproxy marine and terrestrial paleorecords, modeling results, and modern datasets are welcomed.
