Climate change and international diplomacy in Antarctica
Authors: Rowan Howard-Williams
Year Published: 2022
Document Type:
Cold Call Articles
Ownership: Antarctic Science Platform
Summary: How climate change affects Antarctica is going to influence the speed and severity of changes in New Zealand and the rest of the planet. Climate change is a priority topic in Antarctic governance. Next year the Antarctic Treaty Consultative Meeting has dedicated a day to consider the implementation of recommendations in a landmark climate change report. Those discussions will take place in a unique policy setting, almost as unusual as Antarctica itself, because the continent is ‘governed’ by an international treaty system.
Survival of emperor penguins depends on emissions reductions
Authors: Rowan Howard-Williams and Michelle LaRue
Year Published: 2022
Document Type:
Cold Call Articles
Ownership: Antarctic Science Platform
Summary: Emperor penguins are an iconic Antarctic species, but their dependence on sea ice means they are expected to be impacted substantially by climate change.
Antarctic Sea Ice #2: Biological Importance
Authors: Kyle Clem, Rob Massom, Sharon Stammerjohn and Phillip Reid
Year Published: 2022
Document Type:
Reports
Ownership: Scientific Committee on Antarctic Research
Summary: Antarctic sea ice, in the form of immobile coastal “fast ice” and the more extensive moving pack ice 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. This summary on SCAR's Antarctic Environments Portal is based on the best available science.
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
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
Year Published: 2022
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.
On the Precipice
Authors: GNS Science—Te Pū Ao, Te Herenga Waka—Victoria University of Wellington and Antarctic Science Platform
Year Published: 2021
Document Type:
Reports, Papers
Ownership: GNS Science—Te Pū Ao
Summary: The numbers are sharp and the repercussions alarming — but it’s not too late. We still have a chance to curb CO2 emissions before we reach a climate tipping point.
