Climate Variability and Change
We have prepared this information about climate variability and change from a New Zealand perspective as a public service.
- Natural Variations in Climate
- El Niño and Climate Forecasting
- Past Climate Variations over New Zealand
- The Greenhouse Effect
- Greenhouse Gas Measurements
- The Intergovernmental Panel on Climate Change
- Global Climate Models
- Climate Change Scenarios for New Zealand
- Regional Impacts
- UN Framework Convention
- Climate change and the New Zealand marine environment
Some of the pages have been written for members of the public interested in climate change issues, without assuming much technical knowledge. These include the pages on natural variations in the climate, past climate, the greenhouse effect, greenhouse gas concentrations, and the first part of the El Niño page.
Other pages contain more technical detail. These aim to make research results from NIWA scientists and their overseas colleagues readily available to people who need information for developing strategies for addressing greenhouse gas emissions, or for adapting to variation and change in the climate.
Knowledge about the climate system is growing. We will update these pages to reflect new results from NIWA research, and important new findings from international science.
Preparation of these pages was supported by Foundation for Research Science and Technology contracts C01628 and C01X0202.
