Nobody can predict earthquakes, but we can forecast them. Here’s how

Dee Ninis, Monash University and Matthew Gerstenberger, GNS Science

We may never know exactly when the next big quake will hit – but we can have a pretty good idea of the odds.

The Zealandia Switch drove rapid global ice retreat 18,000 years ago. Has it switched to a new level?

Rocks deposited by vanishing glaciers in the Southern Alps thousands of years ago hold climate clues about the past, painting a bleak picture about the long-term survival of alpine ice in New Zealand.

Widespread collapse of West Antarctica’s ice sheet is avoidable if we keep global warming below 2℃

Dan Lowry, GNS Science; Mario Krapp, GNS Science, and Nick Golledge, Te Herenga Waka — Victoria University of Wellington

A new modelling approach improves projections of Antarctica’s future ice loss. It shows a low-emissions scenario would avoid the collapse of West Antarctica’s ice sheet and limit sea-level rise.

A significant number of New Zealanders overestimate sea-level rise — and that could stop them from taking action

Rebecca Priestley, Te Herenga Waka — Victoria University of Wellington; Richard Levy, GNS Science; Taciano L. Milfont, University of Waikato; Timothy Naish, Te Herenga Waka — Victoria University of Wellington, and Zoë Heine, Te Herenga Waka — Victoria University of Wellington

Survey respondents who overestimated the amount and speed of sea-level rise were more likely to express greater concern. But concern is not always helpful in prompting action.

New cyclone forecasts: why impacts should be the focus of hazardous weather warnings

Sally Potter, GNS Science

At the start of the cyclone season in the Pacific, weather forecasters are changing their warnings to focus less on weather information and more on the damage expected from an impending storm.

Can we safely burn waste to make fuel like they do in Denmark? Well, it’s complicated

Thomas Cole-Hunter, Queensland University of Technology; Ana Porta Cubas, University of Sydney; Christina Magill, GNS Science, and Christine Cowie, UNSW Sydney

Waste-to-energy incinerators could help Australia deal with its mounting waste crisis, but burning rubbish may come with risks to public health.

Bila pemanasan global melebihi 2°C, lelehan es Antarktika bisa menaikkan muka laut hingga 20 meter

Georgia Rose Grant, GNS Science and Timothy Naish, Te Herenga Waka — Victoria University of Wellington

Penelitian terbaru menunjukkan pemanasan lebih dari 2°C menjadi titik penting bagi lapisan es di Antarktika, yaitu pencairan es secara besar-besar dan perubahan garis pantai di masa mendatang.

If warming exceeds 2°C, Antarctica’s melting ice sheets could raise seas 20 metres in coming centuries

Georgia Rose Grant, GNS Science and Timothy Naish, Te Herenga Waka — Victoria University of Wellington

New research shows that warming by more than 2°C could be a tipping point for Antarctica’s ice sheets, resulting in widespread meltdown and changes to the world’s shorelines for centuries to come.

How we traced the underwater volcanic ancestry of Lord Howe Island

Maria Seton, University of Sydney; Nicholas Mortimer, GNS Science, and Simon Williams, University of Sydney

Lord Howe Island is part of an underwater volcanic chain much older than first thought, with the possibility of new islands still to form.
