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

One of the best ways to reduce the likelihood of Covid-19 being transmitted in Aotearoa New Zealand classrooms is simply by opening doors and windows to create natural ventilation, say NIWA air quality experts.
New NIWA-led research shows increasing flood risk is going to be what leads people to make changes to adapt to sea-level rise.
Aotearoa New Zealand has just experienced its warmest winter on record – well exceeding the previous record which was set just last year.
Without the global CFC ban we’d already be facing the reality of a “scorched earth”, according to researchers measuring the impact of the Montreal Protocol.

Our work

Regional-scale climate projections assist local authorities to assess risks presented by climate change now and prepare their communities for the future impacts.
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.

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.”

Coastal communities around New Zealand are getting a say on how to respond to sea-level rise, and NIWA is helping them.

This list of resources will support your climate change adaptation planning.
Adapting to climate change is dynamic and uncertain. This step provides guidance on how you can keep your analysis, decisions and responses relevant and up-to-date in a continually changing environment.
This step will help you identify options for action, bearing in mind that often decisions have to be made with limited information.
In this step you will identify your climate change risks, compare them to other (non-climate) risks affecting you face and piroritise your responses.
This step helps you assess your resilience to current climate risk.
This step helps you understand risk, climate and adaptation, as well as reasons to adapt.
This Toolbox helps you find out about the changing climate, what it might mean for your business, organisation or community and what you can do about it.
A senior NIWA scientist is concerned many councils are having difficulty “getting off the starting blocks” when it comes to planning for coastal climate change.
