NZ Antarctic Society raises critical issues about Antarctica

At COP 21 (2015) in Paris the world’s nations agreed to commit themselves to pathways for reducing greenhouse gas emissions to a level that would keep global temperature well below 2°C. Despite significant effort, those tracking emissions reduction are reporting that these efforts are well short of what is needed. And now the climate science community are reporting that the consequences from emissions are more serious and widespread than projected.

COP-28 in Dubai eight years later is a significant waypoint when Earth System science is clearer than ever before. Here the NZ Antarctic Society presents a 12-page Supplement with critical reviews from the last two issues of its magazine Antarctic. The first, by Dr Natalie Robinson, marine physicist at NIWA, reports on the recent reduction in the Antarctic sea-ice fringe weakening deep ocean circulation, and the consequences. The second, by Professor Tim Naish, Victoria University of Wellington, reviews the dire state of Earth’s cryosphere, including the Antarctic, and justifies more attention.

Together they summarise in a few pages real challenges growing from lesser-known parts of the Earth System. These can only be addressed by planned commitments to substantial and continuing reductions in greenhouse gas emissions, which must be the goal for those meeting in Dubai over the next two weeks.

Their concerns are underscored by two new reports released this month from the international community – The State of the Cryosphere 2023, and the International Science Council’s Policy Brief on Global Sea Level Rise.
