I present research that improves our understanding of the glacial history of the Antarctic Ice Sheet and advances the method of in situ 14C exposure dating. Firstly, I present research investigating deglaciation in the Weddell Sea Embayment (WSE) sector of the Antarctic Ice Shee…
Glacial isostatic adjustment (GIA) is the ongoing response of the viscoelastic solid Earth, oceans and the gravitational field to the previous burden of the ice loads. The Earth’s surface was once covered with massive ice sheets, and melting of these ice sheets is still reshapin…
Sea-level rise is a problem that affects regions worldwide - from the marshlands of the San Francisco Bay Area to the farmlands in coastal Bangladesh. Three-dimensional ice sheet models are the principle tools to evaluate mass loss from ice sheets that contribute to sea-level ri…
"The effects of three feet of sea-level rise will be massive. Nine feet will be catastrophic. Incursions of salt into the water table will destroy most of our best agricultural land--for instance, the Central Valley of California--and corrosion will devour the electrical and fib…
Sea level rise will happen no matter what we do. Even if we stopped all carbon dioxide emissions today, the seas would rise one meter by 2050 and three meters by 2100. This--not drought, species extinction, or excessive heat waves--will be the most catastrophic effect of global …
"By 2050: the sea will rise by 2 to 3 feet. Wealthy coastal cities will fight the rising water with dykes and levees; others will lose their underground infrastructure (including electric and fiber optic systems), and face building collapses." "By 2300: the sea will rise by 65 f…
