The Scientific Committee on Antarctic Research (SCAR) is pleased to announce the appointment of Dr Ryan Fogt as Antarctic Environments Portal Editor.
Dr. Ryan Fogt is a Professor of Meteorology in the Department of Geography at Ohio University, in Athens, Ohio, USA. His recent research examines the Antarctic pressure and sea ice variability from the early 20th century to present using observations and statistical reconstructions. When he was a graduate student at the Byrd Polar and Climate Research Center, Ryan was able to deploy to Antarctica three times to work on improving a weather forecasting model used in the U.S. Antarctic Program and adapted to the Antarctic environment, by interacting with forecasters on-site at the U.S. base McMurdo, as well as a special visit to the Amundsen-Scott South Pole station.
Ryan previously served as the Antarctic chapter editor for the Bulletin of the American Meteorological Society’s State of the Climate report from 2008-2015. This experience, along with a decade and a half of teaching and working with undergraduate and graduate student researchers at Ohio University, has helped him grow to be an effective communicator of the complex climate of Antarctica to a wide and diverse audience. Ryan is also a steering committee member to SCAR’s Scientific Research Programme AntClimNow, and serves as their membership coordinator.
Reflecting on his new role, Ryan states,
“I’m really honored and excited to serve as the next editor for the Antarctic Environments Portal. This opportunity will allow me to be more active within SCAR at a higher level, and importantly learn more about other aspects of the Antarctic environment I rarely focus on in my own research. I’m also looking forward to getting involved with Antarctic Policy, and how the portal can better suit the needs of the Antarctic Treaty System and the various initiatives across SCAR that bridge Antarctic science and policy.”
Ryan will begin his role in November 2024 and can be reached at [email protected].
Dr Ryan Fogt will take over from outgoing Editor Dr Keith Reid, whose dedication has ensured that the Portal provides Antarctic decision-makers with accurate, up-to-date scientific knowledge. We would like to thank Keith for all his hard work and wish him the very best for the future.

A new publication on trends and future projections of Antarctic Sea Ice has just been published on the Portal.

This summary is the third article in a series on Antarctic Sea Ice. Read Antarctic Sea Ice #1 and Antarctic Sea Ice #2 here.
Since reliable and continuous satellite records began in 1979, there have been strong regionally- and seasonally-varying patterns of change and variability in sea-ice extent around Antarctica (Fig. 1) – in contrast to a largely uniform loss of sea ice across the Arctic. Notably, the region west of the Antarctic Peninsula to the eastern Ross Sea has experienced significant sea ice loss in concert with a strengthening of the Amundsen Sea Low and increased warm northerly winds. On the western Peninsula, the sea ice loss and associated regional warming has led to dramatic and complex ecosystem change (see Antarctic Sea Ice #2) and has also been implicated in major ice-shelf disintegration events on the Peninsula (see Antarctic Sea Ice #1). Elsewhere, sea-ice coverage has expanded but with substantial interannual variability. The sum of these differing regional and seasonal contributions is a slight increasing trend in overall sea-ice coverage of 1.0 ± 0.5% per decade (or about 11,300 km2 per year) for 1979–2018 (Fig. 1a).
Since 2012, sea ice in the Antarctic has undergone rapid and unanticipated swings in its net overall coverage, to first record high (2013-2015) then record low (2016-2022) coverage. Determining the drivers and effects of these abrupt shifts, together with differing seasonal and regional contributions, is a major focus of current research. This represents a substantial challenge given the complex processes involved in ice-ocean-atmosphere interactions and feedbacks. But better understanding of these interactions and feedbacks is crucial to improving the representation and simulation of sea-ice coverage and seasonality in climate and Earth System models. This is pivotal to improving near-term forecasting and long-term projections of Antarctic sea ice and the effects of sea ice change on the coupled climate-ocean-biosphere system in the coming decades.

“Antarctic Sea Ice #2: Biological Importance” has just been published on the Antarctic Environments Portal.
This Information Summary is part of a series. Read Antarctic Sea Ice #1 and Antarctic Sea Ice #3 here.
Antarctic sea ice, in the form of immobile coastal “fast ice” and the more extensive moving pack ice (see Antarctic Sea Ice #1), supports one of the most extensive and productive ecosystems on Earth and is crucial to the structure and function of Southern Ocean marine ecosystems that are highly attuned to its presence and seasonal rhythms.
Changes in Antarctic sea-ice coverage and seasonality, thickness (and snow cover depth) and properties have wide-ranging consequences with cascading effects across food chains. These effects include:
Looking to the future, sea-ice coverage is predicted to significantly decrease by the end of this century in response to anthropogenic warming (see Antarctic Sea Ice #3), leading to significant reductions in ice-associated primary production and sea ice-dependent species – including Antarctic krill, Antarctic Silverfish, Adélie and Emperor penguins, Weddell and other pack-ice seals, and southern minke and other whale species.

We have just published a new Information Summary on the physical role and function of Antarctic Sea Ice.
This summary is the first article in a series on Antarctic Sea Ice. Antarctic Sea Ice #2 and Antarctic Sea Ice #3 has also been published on the Portal.
Each year around Antarctica, sea ice transforms a vast area of the surface of the Southern Ocean, covering up to 19-20 million km2 at its maximum extent in September (~4% of Earth’s surface) before diminishing to 2-4 million km2 in February. This remarkable annual cycle has an immense influence on the Southern Ocean environment and beyond. The sea ice also accumulates snowfall, which substantially influences its physical and optical properties, its growth and decay, and its interactions with other parts of the ice-ocean-atmosphere system.
Improved knowledge of Antarctic sea ice characteristics and ice-ocean-atmosphere-biosphere processes, interactions, and feedbacks is required to develop and improve Earth System models. Such knowledge is crucial to reducing current uncertainties in those models and to improve confidence in projections of the Antarctic sea-ice system over the coming decades and beyond (see Antarctic Sea Ice #3), including its impacts and coupled feedbacks. Improved sea-ice forecasting capability is also required to support safe and efficient shipping and logistical activities around the Antarctic continent.

A new Information Summary on ten main scientific messages on risks and opportunities for life in the Antarctic has just been published.
The summary was initiated by the SCAR scientific research programme “Antarctic Thresholds – Ecosystem Resilience and Adaptation” (AnT-ERA, 2013-2021). 26 experts synthesized knowledge on impacts and risks of climate-change on biological processes and ecosystem functions in the Antarctic.
The ten main scientific messages that emerged addressed (1) accelerating marine and terrestrial biogeochemical cycles, (2) response to ocean acidification, (3) ecological changes in climate change hot spots, (4) unexpected dynamism of marine seafloor communities, (5) biodiversity shifts, (6) low temperature limitation of protein synthesis, (7) life intrinsically linked to changing sea ice conditions, (8) pollution, (9) genetically distinct terrestrial populations under threat, and (10) newly discovered habitats.

The Antarctic Environments Portal (www.environments.aq) has been developed to support evidence-based management of Antarctica, by placing the best available science knowledge at the fingertips of Antarctic decision makers.
The Portal is an online resource of information on Antarctic environments that supports the work of the Antarctic Treaty System – in particular the Committee for Environmental Protection (CEP). Information in the Portal is unbiased, a-political and presented in a synthesised, or “policy-ready” form.
Since 1961 the Scientific Committee on Antarctic Research (SCAR, www.scar.org), an independent non-governmental body, has been the principal provider of independent, sound, scientifically based advice to the Antarctic Treaty Parties. The Antarctic Environments Portal provides SCAR with a mechanism to ensure continuous availability of timely, topical and up-to-date scientific advice to the Parties.
The Portal presents content in the four official languages of the Antarctic Treaty.
The Portal is hosted and managed by SCAR with funding or in-kind support provided by several Antarctic Treaty Parties. A Portal Management Board oversees the management of the Portal.
The Editor has lead responsibility for generating material for the Portal (mainly by commissioning from external authors) as well as managing the editing and review process.
An international Editorial Group, comprised of volunteers, assists the Editor with the review of content for the Portal. The Editor is responsible for coordinating the Editorial Group and works with the Assistant Editor and the SCAR Secretariat to manage the material posted on the Portal website.
The main role of the Editor is to manage the development of content for publishing in the Portal and the regular updating of existing Portal content, working closely with the Assistant Editor and SCAR.
Main duties include:
