Major regional changes are occurring in Antarctic sea ice coverage
2016 Key Finding2016For the past 30 years, there has been a small increase in the extent of sea ice around Antarctica, but with strong regional differences. Most notable are contrasting regional changes in sea ice seasonality attributed to changing patterns of large-scale atmospheric circulation. In the...
Approach - Land 2016
2016 Report Content2016 Land This report takes a broadly similar approach to the Land chapter in the 2011 state of the environment report (SoE 2011; SoE Committee 2011), and is intended to be an update of that material. A significant addition in 2016 is an attempt to...

Introduction 2016
2016 At a glanceAntarctica is the southernmost continent. Including all islands and ice shelves, it covers an area of about 13.9 million square kilometres (km2)—nearly twice that of Australia. The sea ice that surrounds Antarctica adds about another 19 million km2 at its maximum extent in September–October...

Several factors, such as ocean acidification, increasing wind strength and changes in ocean circulation in the Southern Ocean, may affect the base of Antarctic food webs
2016 Key Finding2016 Dissolved carbon dioxide acidifies the ocean and reduces the availability of carbonate ions that shell-making organisms require for calcification, reducing the ability of these organisms to form shells. This may affect their reproductive capabilities and recruitment. Changes in the...

Outlook for the Antarctic environment 2016
2016 At a glanceAt a glanceCurrently, the Antarctic environment is still in a comparatively good condition. However, the pressures on the continent and the surrounding ocean will increase. For example, the extraction of marine resources is not only going to continue but will intensify in the future. Most...
Antarctica is warming, although changes in atmospheric circulation brought about by the Antarctic ozone hole have been a temporary mitigating factor that has reduced the overall amount of warming, primarily in summer
2016 Key Finding2016During the past half-century, western Antarctic surface temperatures have shown general warming trends, with significant regional patterns. Cooling of the lower stratosphere because of ozone depletion in spring and early summer has helped to mitigate the amount of warming during the...
