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

The latest climate change facts you need to know:

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

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 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.
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 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.

Climate data and common terms explaining the causes and effects of climate change.

Projections of how climate change is likely to affect New Zealand.

Large areas of the ocean, such as the north Tasman and Mediterranean Seas, are low in nutrients with only limited growth of phytoplankton, the microscopic plant cells at the base of the food chain.
