Climate changes, impacts and implications for New Zealand

Robust, up-to-date climate projections are needed to improve understanding of potential impacts and implications of climate change on New Zealand’s environment, economy and society.

The CCII (Climate Changes, Impacts & Implications) project ran from 2012 to 2016 and aimed to update and improve projections of climate trends, variability and extremes across New Zealand out to 2100, based on the latest global projections. 

It generated new knowledge about the potential impacts of climate change and variability on New Zealand’s environment, including our natural ecosystems and native species, and the impacts on the many productive activities which depend on the environment and enable continued growth and prosperity.

The project had five inter-related research aims:

  • RA1:  Improving climate projections.
  • RA2:  Identifying pressure points, critical steps and potential responses.
  • RA3:  Identifying feedbacks, understanding cumulative impacts, and recognising limits.
  • RA4:  Enhancing capacity and increasing coordination to support decision-making.
  • RA5:  Exploring options for New Zealand under different global climates.

The research was funded by the Ministry of Business, Innovation and Employment. It was a collaboration between NIWA, Landcare Research – Manaaki Whenua, Bodeker Scientific, Scion Research, Plant and Food, Victoria University of Wellington, PS Consulting, AgResearch, Motu, Waikato University, the Department of Conservation and GNS Science.
