Climate change

A new international study using ancient swamp kauri from Northland shows a temporary breakdown of Earth’s magnetic field 42,000 years ago sparked major climate shifts leading to global environmental change and mass extinctions.

NIWA’s flagship research vessel Tangaroa leaves soon on a six-week voyage to Antarctica, making it one of the few full scientific expeditions to the continent since the global outbreak of COVID-19.

A new study has identified seven freshwater species native to Aotearoa-New Zealand that will likely be highly or very highly vulnerable to climate change.

NIWA is using serious games to look at problems holistically, support understanding and give a framework for adaptation decisions.

Glaciers are beautiful to see and are a majestic, pristine part of our natural landscape. But what exactly is a glacier, and how do they work?

We can explore how the world may change due to climate change by creating climate models.

Some of the most striking images of lockdown around the world have been the blue skies of cities ordinarily choking in smog. From New Delhi to Los Angeles, Beijing to Paris, the changes were so remarkable they were visible from space.

New Zealand’s climate can be defined as ‘temperate’. However, every so often we experience extremes.

When we talk about the future, we often talk about climate change.

Among the multitude of New Zealand climate statistics there is one record that continues to be broken month after month.

Scientists analysing end-of-summer snowline survey photos have estimated that 13 million cubic meters of ice have been lost from just one glacier from 2016 to 2019.
