Assessing and validating the NZESM using modern and historic observations
The NZ Earth System Model (NZESM) is designed to simulate how our climate will change over the coming decades. It’s highly complex, modelling everything from weather systems to changes in Antarctic sea ice, ocean temperatures to stratospheric chemistry.
Robust adaptation decision making under uncertainty: an application of real options analysis to decision making in the water sector
We all need water, but climate change is putting the availability, supply and distribution of water under increasing pressure. Through drought, erratic rainfall, an expanding population and a growing economy, our access to water is at risk and we need to adapt.
The impact of climate change on New Zealand’s frozen water resources
New Zealand is projected to warm by 1-4°C during the 21st century. This warming will melt our frozen water resources – our snow, ice and glaciers. However, the scale, area and timing of changes to our meltwater are unclear.

New Zealand is projected to warm by 1-4°C during the 21st century. This warming will melt our frozen water resources – our snow, ice and glaciers. However, the scale and timing of changes to our meltwater aren't clear. We need improved water projections for the development of robust climate adaptation policy.

Snow is the perfect place to store water over winter before nature releases it over spring and summer, in time for the irrigation season. The seasonal snow storage acts as an uncontrolled reservoir with the natural release of water into streams aligning well with the needs of growing plants.
