Their findings reveal that 8000 years ago the glacier thinned as fast as it has in recent decades, providing an important model for its future behaviour. The glacier is currently experiencing significant acceleration, thinning and retreat that is thought to be caused by ‘ocean-driven’ melting; an increase in warm ocean water finding its way under the ice shelf.
After two decades of rapid ice loss, concerns are arising over how much more ice will be lost to the ocean in the future. Model projections of the future of PIG contain large uncertainties, leaving questions about the rate, timing and persistence of future sea level rise. Rocks exposed by retreating or thinning glaciers provide evidence of past ice sheet change, which helps scientists to predict possible future change. The geologists used highly sensitive dating techniques, pioneered by one of the team, to track the thinning of PIG through time, and to show that the past thinning lasted for several decades.

We combine measurements of ice velocity from Landsat feature tracking and satellite radar interferometry, and ice thickness from existing compilations to document 41 years of mass flux from the Amundsen Sea Embayment (ASE) of West Antarctica. The total ice discharge has increased by 77% since 1973. Half of the increase occurred between 2003 and 2009. Grounding-line ice speeds of Pine Island Glacier stabilized between 2009 and 2013, following a decade of rapid acceleration, but that acceleration reached far inland and occurred at a rate faster than predicted by advective processes.
Unlike lower-latitude volcanoes which are typically obscured extensively by vegetation, volcanic outcrops in Antarctica are characteristically very clean and beautifully exposed. In places such as northern Victoria Land, cliff sections up to 2 km high extend 10 or 20 km laterally . However, many volcanoes have minimal exposure or have been extensively removed by multiple overriding ice sheets, particularly in the Antarctic Peninsula. A curiosity of subglacially erupted volcanoes is that, because they are formed of alternating thick sections of lavas and fragmental rocks and are therefore technically stratovolcanoes, the frequent development of lava-fed deltas (see below) has resulted in volcano profiles with slopes less than 15° that are normally associated with (lava-dominated) shield volcanoes. Both terms have been used to describe Antarctic volcanoes.

Wrabbit...... really? Ice is melting?
Holy cow, there is way too much info there and between you and the other posters I am subdued. This is why I'm banned from the science forums.
So does this mean global warming is real, or false, or has nothing to do with any of this?
Not kidding, and Snarky, by the 7th grade all my teachers did was suspend me.
