Droughts are economically, environmentally and socially disruptive. Currently, we don’t know the likelihood of future droughts or how they will change in location or intensity because of climate change. We also don’t know what risks these kinds of droughts might pose to our drinking water supply systems in New Zealand.
Improving the simulation of stratospheric chemistry in the NZESM
The aim of this project is mainly to improve the simulation of stratospheric chemistry in the NZ Earth Systems Model (NZESM). Stratospheric ozone is particularly relevant to climate change in the southern hemisphere because of the emergence, in every spring, of the ozone hole above Antarctica.
We are used to thinking of natural hazards as unpredictable, one-off events like earthquakes. And our legal and policy framework is set up for such sudden and unpredictable natural hazards. But sea-level rise policies should not be like natural hazard policies, because sea-level rise is locked in and gradual.

Facing the faraway threat of sea-level rise, responses range from, “Your place, your problem!”, to “Don’t worry, the government will take care of it.” But unless we consider the issue and respond ethically, it’s very likely that the risks of sea-level rise will not be shouldered fairly.
Just the ticket! The Deep South Challenge contributes not one, not two, but up to four “tickets” to improve the world’s centralised global climate model
In the specialised world of New Zealand climate modelling, contributing to the Unified Model, run by the UK Met Office, is the ultimate success story.
A new report by the Deep South Challenge: Changing with our Climate, explores what we need to know now, in order to adapt to the drought conditions likely under future climate change.
