Whales are rediscovering their old haunts in the Arctic and Southern oceans after centuries of hunting.
The Perito Moreno glacier in Patagonia. The sheer number of seracs gives the impression that the glacier’s surface is covered in dragon scales.

The parable of the dragons underlines the need to apprehend glacier disappearance in a transdisciplinary way, to create a dialogue between the physical, ecological and philosophical sciences.
A new climate model combines data on ice loss from both polar regions for the first time.

Climate scientist predict that the combined effect of ice loss in Greenland and Antarctica will be more extreme weather, with impacts on agriculture, infrastructure and human life itself.
Think Arctic, think stranded polar bears? There’s more to it than that.
Expanding protected areas to safeguard the unique biodiversity, such as these emperor penguins, is just part of the Australian research role in Antarctica.

The Australian government’s blueprint for the Antarctic is due out soon. Given the recent cuts in public funding for science, what hope is there for any extra monies for the polar region. And what should…
Icebergs calve from the Larsen Ice Shelf in Antarctica.

Over recent decades, scientists have watched the Arctic and Antarctic polar regions respond in starkly different and perhaps surprising ways to the effects of increasing human influence on the Earth’s…

Foundation essay: This article on the future of the Arctic by Tavis Potts, Senior Lecturer in Oceans Governance at the Scottish Association for Marine Science, is part of a series marking the launch of…
Failing to reach a decision on protecting Antarctic waters doesn’t mean the process is over.

The annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) wound up in Hobart on Thursday last week without declaring a system of marine protected areas (MPAs…
By studying ice cores, researchers can measure the methane emissions from thousands of years earlier.

The past is the key to the future. When snow falls on polar ice sheets, in Greenland and Antarctica for example, air is trapped between the snowflakes. Year after year, the snow compacts under its own…
Sea levels are rising globally at record-breaking rates and Antarctica is playing an increasing role.
Matt King
A small slice of Antarctica turns up along your coastline each year. We’re all glad it’s just a small slice, given Antarctica could deliver a total sea-level rise of 59 metres. That’s not going to happen…
Competing proposals for the Ross Sea could give CCAMLR an excuse to shelve protected areas.

This week delegates from around the globe are gathered in Hobart for the annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR, pronounced “camel-ar” to those…
Methane locked under the Arctic ice could take climate change to a whole new level.
Antonio Delgado Huertas
The risk with climate change is not with the direct effect of humans on the greenhouse capacity of Earth’s atmosphere. The major risk is that the relatively modest human perturbation will unleash much…
Long-time environmental campaigner Geoff Mosley and former leader of the Greens Bob Brown will host a forum in Hobart on 17 June to discuss their proposal to seek World Heritage listing for Antarctica…
Australia’s newly declared continental shelf may be as big as its land mass, but its not a stealth attack on Antarctica.
AAP
Despite recent commentary in the media, Australia’s proclamation of its extended continental shelf does not represent new “claims” in Antarctica and does not contravene the Antarctic Treaty. With Australia…
