New research comparing the geology of southern Africa with the deep seafloor near New Zealand challenges conventional views of how the planet behaved when it was very young.
Seafloor sediments from beneath the Ross Ice Shelf represent an archive of warmer periods in Earth’s past. An ambitious international project aims to uncover what we can learn about our hotter future.
Stringent measures are needed to prevent plastic pollution. But concerns about carbon leaching from plastic waste would be better aimed at emissions from producing more plastic in the first place.
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.
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.

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.
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.
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.
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.
