ABSTRACT: A major objective of earth and climate sciences is to understand the underlying operation of Earth\u2019s climate system. Late-Pleistocene ice ages represent the largest changes in Earth\u2019s climate over the past one million years. The most recent glacial-to-interglacial transition represents the last time atmospheric CO 2 rose by a substantial amount prior to the industrial period. However, our understanding of future climate sensitivity is uncertain, with current estimates ranging from 1 – 6
\n\u00b0C rise per doubling of atmospheric CO 2 (IPCC, 2014). Thus, a more complete understanding of the last glacial termination will hone our understanding of basic climate dynamics and allow ongoing global warming to be placed into a paleoclimatic context to help to improve accuracy of future climate predictions. This talk will present glacier chronologies of the last glacial maximum and subsequent recession from locations along a north-south Australasian transect: the Southern Alps of New Zealand, the Mongolian Altai Mountains, and the Haizi Shan of western China.\u00a0These emerging chronologies allow us to reconstruct local climates and answer important questions about forcing factors that punctuated and subsequently ended the last ice age.<\/p>\n

BIOGRAPHY: Peter Strand is a PhD candidate at the University of Maine. His research uses a range of geomorphologic and geochemical techniques, such as 10 Be and radiocarbon dating, along with glacial\u00a0geomorphic mapping aided by drone. Peter\u2019s research has brought him to many corners of the world. His field areas include: Eastern Tibetan Plateau; Mongolian Altai Mountains; Southern Alps of New Zealand; Northern Andes, Peru; and Dry Valleys, Antarctica.<\/p>\n","protected":false},"excerpt":{"rendered":"
