The North Rift crack on the Brunt Ice Shelf in February 2021. Currently, the Antarctic Peninsula, an area that has seen more than half its ice shelves lose mass, is responsible for around 25% of all ice loss from Antarctica. Monitoring Desk Clinging to the underside of ice hundreds of feet thick, strange communities eke out a living, while researchers race to study them before they disappear. ‘Antarctic ice is growing’–Well, probably not, but even if it were, we are not off the hook (Part of the How to Talk to a Global Warming Skeptic guide). We have three species that reside here, Antarctic fur seals, sub-Antarctic fur seals and long-nosed fur seals (previously called New Zealand fur seals). 6. A portion of the glacier extends out into the ocean as an ice shelf. Antarctic Sea Ice Extent largest since 2015, and GROWING. Melting ice on the edges of the Antarctic continent could be leading to more fresh, just-above-freezing water, which makes refreezing into sea ice easier, Parkinson said. According to the new analysis of satellite data, the Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001.
