So we're starting to build up a picture of something that's more akin to West Antarctica, where the base of the ice sheet is below sea level. (sciencepoles.org)
This raises the probability that - as we've already seen in West Antarctica - if you've got a warming ocean in contact with the ice, it can start to draw down ice which flows more quickly, and this can cause the grounding line to retreat. (sciencepoles.org)

An ice sheet forms through the accumulation of snowfall, in this case on the Antarctic continent, when annual snowfall exceeds annual snowmelt. (newswise.com)

If higher than 2 m above sea level, it is called an ice shelf. (canada.ca)
This will allow scientists to more accurately forecast the fate of the remaining ice shelves and better predict the contribution of Antarctica's ice sheet to sea level rise, as climate changes. (newswise.com)
Ice shelves fringe about three quarters of the Antarctic coast and they play a crucially important role in moderating sea level rise by buttressing and slowing the movement of glacial ice from the interior of the continent to the ocean. (newswise.com)
While ice shelf disintegration doesn't directly raise sea level because they are already floating, the resulting acceleration of the tributary glaciers behind the ice shelf, into the Southern Ocean, does. (newswise.com)
But because the ice is grounded on rock that's below sea level, as the grounding line retreats, the ocean follows the grounded ice further and further back into the interior of the continent. (sciencepoles.org)
However if we go back to the last interglacial - the time before the last ice age, about 120,00-130,00 years ago called the Eemian Period - there are suggestions that sea level was 4-6, perhaps even as much as 9 metres higher than present-day levels. (sciencepoles.org)
With so much water stored in ice sheets, the sea level dropped to about 120 metres below the present level and large parts of the world became extremely arid. (fao.org)
Dr Anna Hogg, study co-author and climate researcher in the School of Earth and Environment at Leeds, said: "If ice sheet losses continue to track our worst-case climate warming scenarios we should expect an additional 17cm of sea level rise from the ice sheets alone. (express.co.uk)

Newswise - Storm-driven ocean swells have triggered the catastrophic disintegration of Antarctic ice shelves in recent decades, according to new research published in Nature today. (newswise.com)
Lead author Dr Rob Massom, of the Australian Antarctic Division and the Antarctic Climate and Ecosystems Cooperative Research Centre, said that reduced sea ice coverage since the late 1980s led to increased exposure of ice shelves on the Antarctic Peninsula to ocean swells, causing them to flex and break. (newswise.com)
Sea ice acts as a protective buffer to ice shelves, by dampening destructive ocean swells before they reach the ice shelf edge," Dr Massom said. (newswise.com)
This is like the 'straw that broke the camel's back', triggering the runaway collapse of large areas of ice shelves weakened by pre-existing fracturing and decades of surface flooding. (newswise.com)

Dr Tom Slater, lead author of the study and climate researcher at the Centre for Polar Observation and Modelling at the University of Leeds, said: "Although we anticipated the ice sheets would lose increasing amounts of ice in response to the warming of the oceans and atmosphere, the rate at which they are melting has accelerated faster than we could have imagined. (express.co.uk)
As the sea ice shrinks, more solar energy is being absorbed by the oceans and atmosphere, causing the Arctic to warm faster than anywhere else on the planet. (sonnenseite.com)

The air bubbles and particles suspended in the ice provide them with valuable insights into climatic conditions and the composition of Earth's atmosphere in earlier eras. (psi.ch)
He added: "Over the past three decades there's been a huge international effort to understand what's happening to individual components in Earth's ice system, revolutionised by satellites which allow us to routinely monitor the vast and inhospitable regions where ice can be found.

Just before impact, each ice chunk - with a mass of just under one kilogram - would have a Kinetic Energy of nearly 800 Joules (K.E. = 1/2*mass*velocity^2), and once the impact happens, that kinetic energy is converted to potential energy. (theweathernetwork.com)

A brittle sheet of ice of that size wouldn't stay intact for long, though. (theweathernetwork.com)
Fragments of this smaller size aren't affected by air resistance as much as the larger sheet of ice, so it would take less than a second for them to accelerate to their new terminal velocity of 41.6 m/s. (theweathernetwork.com)
