Climate change projections

This data provides information about key climate variables such as temperature, rainfall, wind, and drought and how they might change into the future. For example, what might average temperatures look like in Invercargill in 50 years, or how much rainfall could we expect in Taranaki by 2100. These projections were created using six global models, published as part of the Intergovernmental Panel for Climate Change Sixth Assessment Report in 2021, and downscaled to provide New Zealand specific projections at a 5km grid. The data is also provided as a multi model mean or “ensemble”, meaning it shows the average of the values produced by each of the six climate models used by NIWA for the downscaling process. Further information on this process can be found in the reports on Methodology and Bias Correction, or on the NIWA site.
