Antarctic Sea Ice 03 Trends

Antarctic Sea Ice #3: Trends and Future Projections

Authors: Kyle Clem, Rob Massom, Sharon Stammerjohn and Phillip Reid
Year Published: 2022
Document Type: Reports
Ownership: Scientific Committee on Antarctic Research
Summary: 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 – in contrast to a largely uniform loss of sea ice across the Arctic. This summary on SCAR's Antarctic Environments Portal is based on the best available science.

Scientists chart 45 million years of Antarctic temperature change

Authors: Te Herenga Waka—Victoria University of Wellington, GNS Science, and Birmingham University (UK)
Year Published: 2022
Document Type: Papers, Update
Summary: New study shows 'very clear and direct response' of Antarctic temperatures to changing carbon dioxide levels. Molecular fossils and computer modelling have enabled scientists to build the first catalogue of Antarctic ocean temperatures over the past 45 million years, offering new insights into future sea level changes.

Changes in the Ross Sea and the future of carbon storage

Authors: Miles Lamare, Vonda Cummings, Ian Hawes and Rowan Howard-Williams

Document Type: Cold Call Articles
Ownership: Antarctic Science Platform
Summary: The Southern Ocean mops up anthropogenic CO2 emissions. But acting as a ‘sink’ for this excess heat and carbon dioxide is having an effect on the ocean and the ecosystems it supports.

The Southern Ocean carbon sink: Will it fill up?

Authors: Jocelyn Turnbull and Rowan Howard-Williams
Year Published: 2022
Document Type: Cold Call Articles
Ownership: Antarctic Science Platform
Summary: A key question for understanding future climate impacts is what drives the uptake of carbon into sinks, and how that might change. The Southern Ocean absorbs by far the most carbon dioxide of any region of the world.

Summary: One of the coldest places on Earth recently experienced a spike in temperature 40°C above normal. Should we be worried?

Choosing the future of Antarctica

Authors: S. R. Rintoul, S.L. Chown, R.M. DeCento, et all
Year Published: 2021
Document Type: Papers
Summary: We present two narratives on the future of Antarctica and the Southern Ocean, from the perspective of an observer looking back from 2070. In the first scenario, greenhouse gas emissions remained unchecked, the climate continued to warm, and the policy response was ineffective; this had large ramifications in Antarctica and the Southern Ocean, with worldwide impacts. In the second scenario, ambitious action was taken to limit greenhouse gas emissions and to establish policies that reduced anthropogenic pressure on the environment, slowing the rate of change in Antarctica.
