Climate change

Climate change effects are accelerating, driving the need for actions informed by sound climate knowledge.

Climate change

NIWA is committed to providing the science needed to adapt to and mitigate climate change. By making informed choices now, we can reduce risks, maximise opportunities, foster climate resilience and work towards a carbon-neutral economy.

“The challenges of reducing our national greenhouse gas emissions and adapting to a changing climate are hugely important and affect all New Zealanders. The Climate Change Response (Zero Carbon) Amendment Bill provides the framework for responding to these challenges. NIWA’s role – providing research for evidence-based decision-making and science-based solutions to reduce emissions and adapt to our changing climate – is now more important than ever.”

Dr Andrew Tait, Chief Scientist, Climate, Atmosphere and Hazards

The latest climate change facts you need to know:

Latest news

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.
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.
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.
This is one of the most extreme drought events for Auckland in modern times and similar to one experienced in 1993/94.

Our work

Climate Present and Past is a core-funded project under NIWA's National Climate Centre. It aims to explore historical climate data and track past changes in climate through a range of approaches.
Our Future Climate New Zealand is an interactive website that lets you to look at projections for a number of climate variables for New Zealand between now and 2100.
NIWA is developing a national river flow forecasting tool for New Zealand that aims to support and strengthen our planning for and response to extreme rainfall events.
NIWA is using serious games to look at problems holistically, support understanding and give a framework for climate change adaptation decision-making.

Glacier melt: A Time Capsule

Since 2016 enough ice has melted from the South Island’s Brewster Glacier to meet the drinking water needs of all New Zealanders for three years.

Our climate is changing - we need to act now.

Glaciers Don't Lie

If you think New Zealand's Southern Alps are shielded from climate change – take a look at this. "You can't make a glacier lie.”

NIWA works with businesses, organisations, and central and local government to help them understand their climate risks, plan for adaptation, and meet the regulatory requirements for the Taskforce on Climate-related Financial Disclosures (TCFD).
To prepare for changes in climate, our freshwater and oceans decision-makers need information on species vulnerability to climate change.

The NCCRA assessment was commissioned by the Ministry for the Environment and has identified the most significant risks we face from climate change. It will feed into the Government’s national adaptation plan.
This is one of the most extreme drought events for Auckland in modern times and similar to one experienced in 1993/94.
Analysis of drought conditions across New Zealand this year shows it is one of the most severe on record for some regions.
Young New Zealanders can now access the most up-to-date educational material about the science of climate change and its impacts on Aotearoa thanks to NIWA’s new web section: 'Climate change information for climate solvers'
Scientists have recorded more snow on the South Island glaciers this year, but they warn it is simply a temporary break rather than any good news on the climate change front.
Scientists know so little about how storms affect the delicate balance of lake ecosystems that we may be unable to protect them from the effects of climate change, says a NIWA scientist.

NIWA researchers have helped unlock information trapped in ancient air samples from Greenland and Antarctica that shows the amount of methane humans are emitting into the atmosphere from fossil fuels has been vastly underestimated.
