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.
The current estimate is that Earth would warm by 1.5℃ to 4.5℃ if emissions were to double on pre-industrial levels. The range has remained stubbornly wide, despite improved climate modelling.
Imagine if every meal you ate included food previously chewed by someone else. That’s what’s happening to the air we breathe in shared indoor spaces.

Researchers have surveyed an Antarctic under-ice river for the first time directly, and their observations support the idea that such sub-glacial rivers form estuaries as they flow into the ocean.
The ocean has been buffering us from the impacts of climate change, but it is reaching the limit of this capacity. Integrating ocean and climate policy will be crucial.
Ocean waves are a massive source of energy, but it’s challenging to design power generators for the harsh environment. Allowing marine organisms to grow on engineered structures could help.
Given climate change predictions of more extreme floods in New Zealand, it’s time to change management practices to work with a river, allowing it room to move and its channels to adjust.
Une zone océanique tumultueuse où les vagues peuvent atteindre 20 mètres et plus…
L’océan Austral constitue le principal réservoir de chaleur et de carbone de notre planète. Il abrite des formes de vie extraordinaires, des invertébrés microscopiques aux gigantesques baleines.

El Océano Austral (Antártico) es el principal almacén de calor y carbono de nuestro planeta, y es hogar de extraordinarias formas de vida, desde pequeñas algas y criaturas sin espinas hasta pingüinos, focas y ballenas.
The Southern (Antarctic) Ocean is our planet’s primary storage of heat and carbon, and it’s home to extraordinary life forms, from tiny algae and spineless creatures to penguins, seals and whales.
Tropical cyclones account for almost four in five natural disasters across Pacific Island nations. But a new forecasting tool now gives up to four months warning for the upcoming cyclone season.
Latest research explores how a warming ocean circulates underneath Antarctica’s floating ice shelves and how this contributes to future sea level rise.
Auckland’s extreme drought and the rapid retreat of glaciers in the Southern Alps both highlight how important long-term observations are for water management policy and planning.
Scientists measured the thickness and basal melt of the Ross Ice Shelf.
Parts of Antarctica’s largest ice shelf are melting ten times faster than the rest of the shelf, and solar heated waters below the ice are to blame.
This summer, coastal seas to the north and east of New Zealand are even warmer than during last year’s marine heat wave.
Marine heatwaves may become the new normal for the Tasman Sea and the ocean around New Zealand, and oceanographers are developing models to better predict their intensity.
Small aircraft carry scientists high above the Southern Alps to survey glacier changes.
Forty years of continuous end-of-summer snowline monitoring of New Zealand’s glaciers brings the issue of human-induced climate change into tight focus.
The team used hot-water drilling gear to melt a hole through Antarctica’s Ross Ice Shelf to explore the ocean below.
An international team has melted a hole through Antarctica’s largest ice shelf to explore the hidden ocean below, and the shelf’s vulnerability to climate change.
The analysis of large amounts of ice from Antarctica’s Taylor Valley has helped scientists to tease apart the natural and human-made sources of the potent greenhouse gas methane.
Analysis of 12,000-year-old Antarctic ice reveals that methane leaks from fossil fuel extraction play a larger role than previously thought.
The authors have collaborated on an Antarctic research project, investigating tiny ice crystals and their role in climate.
