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.

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.
Choosing the future of Antarctica
Authors: S. R. Rintoul, S.L. Chown, R.M. DeCento, et all

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.
Antarctic ecosystem in transition – life between stresses and opportunities

Document Type:
Papers
Summary: Important findings from the second decade of the 21st century on the impact of environmental change on biological pro-cesses in the Antarctic were synthesised by 26 international experts. Ten key messages emerged that have stakeholder-relevance and/or a high impact for the scientific community.
