DSC Seminar #7 | Global ocean modelling in the Deep South Challenge

Wednesday 30 May, 12.30–1.30pm
With Erik Behrens (NIWA)

The oceans are the largest ecosystem on our planet, with complex physical and bio-geochemical interaction between the atmosphere, sea ice and ice shelves. Oceans are the main storage for human-produced heat and carbon. At the same, oceans have the ability to redistribute heat and carbon both across large distances and over time, which makes them the key component in the climate system.

Coping in the face of climate change: Research announced to better support our communities

A new report released by the the Deep South National Science Challenge, Communities and climate change: Vulnerability to rising seas and more frequent flooding, highlights key gaps in our collective understanding about how climate change will impact Aotearoa New Zealand’s diverse communities.

Climate Adaptation Ambassadors' Workshop: Steering research through to policy and action

This workshop aims to support and develop a community of “climate ambassadors,” who can champion an informed and proactive climate adaptation agenda in research, policy, the public and private sectors and within local communities.

Climate Change and Local Government Forum

Start date
Region:Wellington

The Climate Change and Local Government Forum is an exciting new event featuring New Zealand experts in this area. Mainly (but not exclusively) for local government professionals, it's an opportunity to hear from both climate researchers and local government practitioners facing the challenge of adapting to our changing climate.

DSC Seminar #6 | Counting the cost of climate change: Treasury seminar redux

With Dave Frame, Belinda Storey and David Fleming

Climate change is already making day-to-day life more precarious and more expensive, both for ordinary New Zealanders and for our local and central governments. New Zealanders are increasingly interested in climate adaptation strategies. Conversations about the cost of early adaptation versus the risk of delayed action are growing in volume.

Earth System Modelling and Prediction

Developing and utilising the New Zealand Earth System Model to produce improved projections of climate change.

A ship in the sea

The focus of this programme is to assemble the first New Zealand Earth System Model (NZESM), which sits in the heart of the Deep South Challenge work.

An Earth System Model combines the physical processes of atmospheric and oceanic circulation with the chemical and biological processes that impact the earth system.

Earth system models inform international assessments of climate, such as the assessment reports published by the Intergovernmental Panel on Climate Change (IPCC).
 

Addressing limitations of international models

Developing the NZESM means that we no longer need to base our climate projections on overseas models. This is important because due to their focus on the Northern Hemisphere climate, overseas models often poorly represent some processes in Antarctica and the Southern Ocean. The resulting biases can have serious consequences for the quality of projections over Aotearoa New Zealand.
 

Building on existing work and collaboration

The development of the New Zealand Earth System Model hasn't started from scratch. Existing models provide important building blocks that apply anywhere, and our modellers are supported by strong collaborations with overseas partners.
 

One of few national Earth System Models in the world

Notably, this work puts Aotearoa New Zealand in with the handful of other countries that run their own earth system models, and gives us the resource and expertise to contribute to global climate modelling efforts.

Near-term climate predictions for New Zealand

Improving predictions and understanding deep south drivers of New Zealand’s climate

Climate change is already here. Living in a changing climate means playing catch-up: trying to work out what has changed, what is changing and what changes are just around the corner. Although the dramatic transformations expected later this century get the most attention, the impact of current change is already significant, and is affecting societies now.
