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

Preliminary analysis by NIWA climate scientists has shown that the recent Canterbury rainfall was so extreme in some inland places that it could be expected to happen only once every 200 years.
Farmers visiting NIWA’s Fieldays stand at Mystery Creek next week have the opportunity to see into their future by playing a game that dices with climate change.
The prodigious rainmaker that hit Canterbury earlier this month saw NIWA field teams out in the elements collecting flood data from bridges, cableways and jetboat gaugings.
A Central Otago scientific research station with a globally revered reputation is marking its 60th anniversary.

Our work

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.
Clouds over the ocean, and how they trap or emit radiation from the sun, are partly influenced by the biology, biogeochemistry and physics of the surface ocean below.
Flooding is one of the most costly natural hazards in Aotearoa New Zealand. Our regular flood clean-up bills are topped only by much less frequent earthquakes.
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.

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.”

A joint NIWA and Department of Conservation (DOC) project is extending New Zealand’s ocean acidification monitoring network to include marine reserves.

Scientists undertaking the annual glacier snowline survey over the South Island later this month are keeping a watchful eye on a lake that has been forming and disappearing at the junction of the Tasman and Hochstetter glaciers.
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.
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.
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 climate change adaptation decision-making.
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.
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.
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'
