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

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.

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.
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.

Regional-scale climate projections assist New Zealand’s local government authorities to adequately assess the local risks presented by climate change now and prepare their communities for the future impacts of climate change.
RiskScape, a joint venture between NIWA and GNS Science, is a tool for analysing potential economic and social impacts from multiple natural hazards.

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.
