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.

“When it comes to climate change we are in the beautiful position of knowing what our choices are. We can feel a real sense of opportunity about the future - what role our science can play, and how people can contribute”

Dr Sam Dean, Principal Scientist, Climate, Atmosphere and Hazards

Latest news

Expect to hear a lot more about climate change in the news in the weeks ahead – and a lot about NIWA’s work underpinning the science that is signalling a warmer world right now and its effects in the future.
Two reports released today by NIWA and the Deep South National Science Challenge reveal new information about how many New Zealanders, how many buildings and how much infrastructure could be affected by extreme river and coastal flooding from storms and sea-level rise.
Understanding how the Antarctic oceans work is vital to predicting the world’s future climate and the implications of climate change for humankind and the planet.

The on-going rise of atmospheric carbon dioxide (CO2) that is fuelling climate change is also driving significant changes in the waters off our coasts.

Our work

Glaciers are iconic features of mountain landscapes with significant cultural, environmental, scientific, and economic value. While we know that they are sensitive to changes in their local climate, our understanding of exactly how mountain glaciers will respond to climate change is incomplete.
Adaptive Futures is a 'serious game' designed to introduce players to community-level decision-making and climate change adaptation.
NIWA is conducting a five–year study to map changes in the distribution of plankton species in surface waters between New Zealand and the Ross Sea.
Our oceans are expected to become more acidic as carbon dioxide concentrations rise. This will likely have impacts on the plankton, which play a major role in ocean ecosystems and processes.

Our Climate is Changing

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.”

Ocean acidification - what is it?

The on-going rise of carbon dioxide (CO2) in the atmosphere is not only changing our climate—it is also changing our oceans. Take a look at the work of the NIWA-led CARIM project into what these changes may mean for the delicate balance of marine life.

NIWA Blake Ambassadors vlog1

26 October 2018. NIWA Blake Ambassadors, Lana Young and Siobhan O'Connor and SalpPOOP voyage leader Dr Moira Decima check out sampled salps from different depths.

Antarctic Climate Change

NIWA climate scientist Dr James Renwick explains what changes are occurring in the Antarctic in response to climate change and what's likely to happen in the future.

Climate Change and the Microbial Loop

NIWA biological oceanographer Dr Julie Hall explains how increased sea temperatures are predicted to increase stratification of the ocean, creating a disconnect between the surface waters and deep ocean.

The Microbial Loop

The microbial loop refers to the small microscopic organisms in the ocean – viruses, bacteria, the small phytoplankton and microzooplankton – and the relationships between them.

Sea Ice and Climate Change

Dr Mike Williams, physical oceanographer at NIWA, explains the importance of Antarctic sea ice in the Earth's ocean and climate systems and how they may be affected by climate change.

Climate Change and Deepsea Life

Dr Dave Bowden outlines concerns over the impacts of climate change on deepsea life in Antarctic waters.

Phytoplankton and Climate Change

NIWA biological oceanographer Dr Philip Boyd explains how the Southern Ocean plays a key role in controlling the world's climate, by drawing large amounts of CO2 from Earth's atmosphere into the ocean depths.

Is ocean iron addition part of the solution to climate change? Cliff Law, NIWA explains: 

A decision framework has been developed that provides for a balanced and justifiable prioritisation of sustainable adaptations to climate change and which is flexible to change.
A range of links, contacts and supplementary material.

This toolbox is a resource to help planners, engineers, asset managers, and hazard analysts in New Zealand urban councils understand and evaluate the potential impacts of climate change in their city.

NIWA Oceanographer Dr Craig Stevens has returned, with stunning images and data, from a successful month-long research trip in Antarctica, where he led a team of international and New Zealand scientists.

NIWA’s weather prediction model simulated the intense rainfall which fell just north of the capital, and flooded parts of Porirua, on Sunday 27 March. Thirty nine millimetres of rain fell in less than an hour, around 1.00pm.

More than 30 international experts in climate science will meet in Queenstown this week to discuss implementing a new a state-of-the-art global network to improve the quality of measurements of upper air climate variables.

Over the past decade, predicting the weather, and understanding the changes in climate, has emerged as one of the most important and topical areas of scientific endeavour.

NIWA today released a report reviewing its seven station temperature series, which adds to its analysis of New Zealand’s temperature trends over the past 100 years.

New climate modelling shows seasonal snow levels at New Zealand ski areas will be reduced by the effects of climate change in the coming years, but the good news is the loss may actually be less than originally anticipated and we should be able to continue to make snow, even under a more extreme climate scenario.

Stormwater 2011

3 May 2011 to 6 May 2011

The Stormwater Special Interest Group of Water NZ is holding the 7th South Pacific Stormwater Conference on the 3rd-6th May at the Sky City Convention Centre, Auckland, NZ.
The aim of the 2011 conference is to provide delegates with an opportunity to:

* Upskill in various areas of stormwater science and management
* Network with peers
* Hear new and cutting edge stormwater information

Suggested themes for sessions at the 2011 conference include:

* Low impact design and development
* Success in Stormwater management
* Climate change
* Stormwater and Public Health
* Catchment management

NIWA's work on long-term temperature trends has been subject to various review processes.

Temperature measurements for the Nile St Vicarage in Nelson have now been digitised. These records were used in the NIWA seven-station temperature series
