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.”

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.
While we know that glaciers are sensitive to changes in their local climate, our understanding of exactly how mountain glaciers will respond to climate change is incomplete.
NIWA is using serious games to look at problems holistically, support understanding and give a framework for climate change adaptation decision-making.
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.

CO2 levels measured at Baring Head

The graph shows carbon dioxide (CO2) levels measured at Baring Head, NIWA’s clean air station, near Wellington. This station has been running since 1972 and is home to the longest running continuous CO2 measurements in the Southern Hemisphere.

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.

NIWA is bringing together decision makers and influencers from across New Zealand this month to shape the science we need to respond to our changing climate.
Dr Sara Mikaloff-Fletcher is looking to turn the internationally accepted science of monitoring greenhouse gas emissions upside down—and the rest of the world is watching closely.
Thermal images taken by a NIWA scientist during this year’s aerial survey of South Island glaciers have revealed in extraordinary detail how heat in the surrounding landscape is affecting the ice.
Scientists have taken a step closer to predicting marine heatwaves with new NIWA-led research finding a link between their formation and the length of time sea temperatures are warmer than normal.^.
Part of the world’s largest ice shelf is melting 10 times faster than the overall average and solar-heated waters beneath the ice shelf are to blame, NIWA research has found.
The latest state of the environment report released today provides New Zealanders with clear evidence that our climate, freshwater and marine systems are changing, says NIWA.
CarbonWatchNZ will address crucial carbon cycle questions in the three landscapes that are most important to New Zealand’s carbon balance: forest, grassland and urban environments.
Weather and climate experts from around the world are meeting in Wellington next week to discuss the critical need for accurate forecasting to cope with a changing climate.
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 has crunched the data on this week’s heatwave and come up with the following record breakers
The water in the New Zealand region is significantly warmer than it was 30 years ago, and all indications are the warming trend will continue, says a NIWA scientist.
A trio of lead authors from NIWA has been named alongside the Ministry for the Environment and others as joint winner of the 2018 Terry Healy Coastal Project Award.
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.

Students at Leigh School have been working with marine scientists and the 'Year of the Salps' project partners to learn how to count sea salps, understand salp life cycle phases and the importance of salps in marine ecosystems and their carbon-cycling effects on climate change.
Inhabitants of the Marshall Islands may not be able to avoid drought, but thanks to a new tool co-developed by NIWA they can now plan ahead to better manage water resources when the big dry looms.
