Mid-Holocene Antarctic sea-ice increase driven by marine ice sheet retreat [PDF]
Climate of the Past, 2021 Over recent decades Antarctic sea-ice extent has increased, alongside widespread ice shelf thinning and freshening of waters along the Antarctic margin. In contrast, Earth system models generally simulate a decrease in sea ice.

Antarctic Sea Ice Area in CMIP6 [PDF]
Geophysical Research Letters, 2020 AbstractFully coupled climate models have long shown a wide range of Antarctic sea ice states and evolution over the satellite era. Here, we present a high‐level evaluation of Antarctic sea ice in 40 models from the most recent phase of the Coupled Model Intercomparison Project (CMIP6). Many models capture key characteristics of the mean seasonal cycle

The Monterey Event and the Paleocene‐Eocene Thermal Maximum
Geophysical Monograph Series, Page 401-416., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

First results of Antarctic sea ice type retrieval from active and passive microwave remote sensing data [PDF]
The Cryosphere, 2023 Polar sea ice is one of the Earth's climate components that has been significantly affected by the recent trend of global warming. While the sea ice area in the Arctic has been decreasing at a rate of about 4 % per decade, the multi-year ice (MYI), also ...

Recent changes in Antarctic Sea Ice [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015 In contrast to the Arctic, total sea ice extent (SIE) across the Southern Ocean has increased since the late 1970s, with the annual mean increasing at a rate of 186×10 3 km 2 per decade (1.5% per decade; p <0.01) for 1979–2013.

Impacts of Observed Extreme Antarctic Sea Ice Conditions on the Southern Hemisphere Atmosphere
Atmosphere, 2022 The Antarctic sea ice has undergone dramatic changes in recent years, with the highest recorded sea ice extent in 2014 and the lowest in 2017. We investigated the impacts of the observed changes in these two extremes of Antarctic sea ice conditions on ...

Sensitivity of the Antarctic ice sheets to the warming of marine isotope substage 11c [PDF]
The Cryosphere, 2021 Studying the response of the Antarctic ice sheets during periods when climate conditions were similar to the present can provide important insights into current observed changes and help identify natural drivers of ice sheet retreat. In this context, the
