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

Latest news

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

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.”

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'
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.

2019: New Zealand’s 4th-warmest year on record
There are about 800km between the southern and northern tips of Tonga - and a lot of ocean.
In the past 10 years, more weather records have been broken than in any other time in New Zealand’s history.
New Zealand has just experienced its hottest November on record, according to NIWA climate scientists.
