Climate change risk assessment for land-based activities

This project aims to give land stewards a greater understanding on the most suitable crop options for their land, by providing a holistic understanding of the benefits and consequences of the options. The vision for this research is to identify a greater range of suitable land opportunities and more diverse benefits for New Zealand. Climate... Read more »...

Upper ocean observations during storms

Observing upper ocean variability during storms: connecting event scales to climate responses. The warming of the ocean has a direct impact on the intensity of tropical cyclones. Climate predictions have indicated cyclones will be stronger and wetter as the world continues to warm up. These large-scale weather events can cost up to $40m. Traditional vessel-based...

Future extreme weather in Aotearoa

Extreme weather is the sharp end of climate change. Aotearoa New Zealand is highly vulnerable to the impacts of extreme weather like heavy rainfall and flooding. Homeowners, the government and insurers are just some of those eager to know what the future holds in store. With this public participation project ‘[email protected]’, you can help them...

Simulating New Zealand’s changing climate

Establishing a New Zealand earth system modelling capability A project which sits at the heart of the Deep South Challenge is the development of the NZ Earth System Model (NZESM). An Earth System Model models our oceans, sea ice, land and atmosphere to understand how our climate will change under anthropogenic greenhouse gas emissions.  Gaps... Read more »...

Marine heatwaves and the link with climate extremes

Ocean heat content changes around New Zealand: a link to climate extremes In recent summers, New Zealanders have experienced a series of marine heat waves. Temperatures in some regions have exceeded 6°C above average. While some of us enjoy the warmer water temperatures for water sports and holiday activities, most marine organisms experience heat stress,... Read more »...

Warming in the Tasman Sea

The Tasman Box: filling and warming up The temperature of the Tasman Sea has a strong influence on New Zealand’s climate system. The increasing heat content of the Tasman since the 1990s has resulted in significant sea-level rise, due to thermal expansion of seawater. Marine heat waves are becoming increasingly frequent, and they too have... Read more »...

Melting ice in the NZESM

Freshwater from icebergs and ice shelf melt in the NZESM While the reduction of Arctic sea ice is alarming researchers worldwide, Antarctic sea ice extent has actually been increasing over the past 30 years. Changes in Antarctic sea ice can have a huge effect on weather patterns over New Zealand, causing varying wind patterns that... Read more »...

National flood risks & climate change

Emergent exposure of flood inundation hazards under future climate change in New Zealand Floods are some of New Zealand’s most frequent, most damaging and most disruptive natural hazards. As our climate changes, flooding caused by both increased rainfall and rising sea levels – in coastal areas and on floodplains – is expected to increase. As... Read more »...

Climate impacts on the national water cycle

National hydrological and water resource impacts of climate change This century, climate change will alter New Zealand’s natural water cycle significantly. It will change how much rain and snow we receive, and at what time of year. It will change how much water is stored in the soil, snow, glaciers and aquifers. It will change... Read more »...

Stormwater, wastewater and climate change

Impacts on our economy, environment, culture and society We don’t yet know how climate change will impact our critical stormwater and wastewater infrastructure. We also don’t know the extent to which climate change-induced damage to this infrastructure might directly, or indirectly, impact our economy, environment, culture and society. This project, now complete, explored these potential... Read more »...
