Title: What drives Antarctic ice sheet evolution? Insights from 800,000 year ice sheet simulation with transient climate forcing

Abstract: Antarctic ice-sheet instabilities could become a major driver for future global sea level rise. However, the rate at which Antarctic ice-sheet mass loss will occur is a matter of intense debate and subject to large uncertainties. To further constrain the response of the Antarctic ice sheet to environmental change, it is necessary to study its sensitivity to past changes in greenhouse gas concentrations and orbital parameters. So far, long-term Antarctic simulations have used proxy-based parameterizations of climatic drivers, presuming that external forcings are applied in synchrony with each other. Here for the first time we have used a transient, three-dimensional climate simulation over the last eight glacial cycles to drive an Antarctic ice sheet model. We show that the evolution of the Antarctic ice sheet was mostly driven by CO2 and sea level forcing with a period of about 100,000 years, synchronizing both hemispheres. However, high surface melt and ice-shelf calving rates during precessionally-driven periods of austral summer insolation maxima cause a decoupling of bipolar ice-sheet variations during the warmest interglacials. Sensitivity runs with individual climatic drivers indicate that they add nonlinearly, implying that the full spectrum of climate forcing needs to be considered when evaluating the sensitivity of the Antarctic ice sheet to past and future climate change.

Hot Science - Cool Talk \"Human Mating Behavior\"

October, 27 2017

Time: 7:00 PM - 8:15 PM
Location: Student Activity Center (SAC)

If we all want love, why is there so much conflict in our most cherished relationships? What is evolutionary psychology and how can it provide insights to human mating behavior? Dr. Buss shares insights on how conflict, competition, and manipulation pervade human mating. Dr. Buss is signing his newest book \"The Evolution of Desire\" from 5:45 - 6:30 during Cool Activities. The UT Coop will have books for sale at the signing.

Due to the content of this talk, we recommend it for high school seniors, college students and adults only.
