“Modelling clouds, aerosols and atmospheric chemistry” – project summary by Laura Revell

Earth system models are computational representations of the physical, chemical and biogeochemical processes that occur on Earth. Spanning the global atmosphere, ocean, land surface and sea ice, Earth system models allow us to develop the best possible picture of how physical climate change could play out and affect us here in Aotearoa New Zealand.

The establishment of an Earth system modelling community has been a great success of the DSC. Developing this community took time because Earth system models are highly complex. These are not tools that even a trained scientist can pick up and use right away. Learning how to run them – and better still, improve them – takes equal amounts of skill and time and about ten times as much patience.

Fully maintaining an Earth system model involves large teams of scientists and scientific programmers. Through the DSC we established a partnership with the UK Met Office, who have a world-leading model. In return, we’ve provided improvements to the model targeted over the Southern Ocean. This region of the world is important for determining New Zealand’s climate and weather extremes. However, because it is so remote – especially relative to the major climate modelling centres which are based in the Northern Hemisphere – it is poorly understood, leading to poor-quality simulations of the atmosphere and ocean.

New Zealand’s unique atmosphere

New Zealand’s air and surrounding atmosphere is unique. It is largely free of human-created sources of air pollution seen in many other countries: of 134 countries ranked by air quality in 2023, New Zealand came in at 129 (this is a list we want to be near the bottom of!). However, New Zealand’s air is heavily influenced by the ocean. Breaking waves provide a near-constant source of particulates or “aerosols” to the atmosphere. Smaller than the width of a human hair, aerosols can be transported by winds over large distances. Aerosols originating from the ocean are measured in air throughout New Zealand.

Although they are small, aerosols play an important role in climate change. Like miniature “disco balls”, they scatter sunlight back to space. They also seed cloud formation. Clouds play an important role in the climate system: some cool the surface, while others trap heat in the lower atmosphere. The type of cloud formed is partly influenced by the local aerosol environment. We know for example that clouds over the Southern Ocean are influenced by sulfate aerosol and marine organics. These compounds originate from the surface layer of the ocean, which teems with microscopic life. Gases and particulates emitted from the surface layer can have important consequences for atmospheric composition and climate. Earth system models typically struggle to represent ocean-aerosol relationships accurately over the Southern Ocean, which could explain why the models struggle to represent clouds accurately here too.

A better Earth system model for New Zealand

Through the DSC we’ve worked with the observations team who made cloud and aerosol measurements on the Southern Ocean onboard the RV Tangaroa to understand the atmospheric processes occurring in our backyard and how we should represent them in our Earth system model. We’ve improved how we model aerosol precursors at the ocean surface, emissions of sea spray aerosol from breaking waves, cloud formation and atmospheric chemistry. Through related projects we’ve even leveraged our expertise in Earth system modelling to understand how emerging contaminants such as microplastics aloft in the atmosphere could affect Earth’s climate.

Thanks to our research we can produce more accurate climate change projections for New Zealand and surrounds. We’ve passed on model developments to our partners at the UK Met Office to include in future releases of the Earth system model, which, along with the UK and New Zealand, is used in Australia, South Korea, India and several other countries. In doing so, we’ve also lined up the next generation of Earth system modellers in New Zealand. Collaborations in cloud and aerosol modelling between NIWA and the University of Canterbury have supported the training of young scientists at undergraduate, postgraduate and postdoctoral level. As a community we are well placed to support the need for climate change information in a warming world.

Climate change is happening. The future of Earth system modelling in New Zealand is uncertain.

With the National Science Challenges ending, many New Zealand research communities are struggling to find continuity. With recent refocussing of research priorities at NIWA, much of the country’s expertise in Earth system modelling now sits within the universities, and we are considering how to retain capability long-term in a post-DSC world. Continuing our partnership with the Met Office will maintain access to state-of-the-art Earth system modelling capability. Funding wise, joining international consortia, such as via New Zealand’s recent agreement with Horizon Europe, may be a sensible way forward. Bi- and multi-lateral arrangements also have precedents and could be explored. Ultimately, the scale of 21^st century challenges associated with climate change and novel airborne pollutants means it is firmly in the national interest to ensure that modelling capability in New Zealand remains as robust as the climate challenges the model predicts.

Project summary from the “Modelling Antarctic Sea Ice” project led by Inga Smith and Andrew Pauling.

Check out a handy fact sheet from this project, here.

What is sea ice?

Sea ice is the layer of frozen seawater covering the ocean surface in the northern and deep southern oceans. In Antarctica, the formation of sea ice each winter and melting each summer represents one of the largest seasonal changes on Earth. The total ice cover varies by about 16 million km² between the yearly minimum and maximum. That’s approximately 60 times the size of Aotearoa New Zealand.

The trend in annual mean Antarctic sea ice area has puzzled scientists during the satellite era (1979-present), with data showing a slight increase from 1979 to 2015, and a sharp decline since.

Animation made using model output from the hist-1950 simulation from the HadGEM3-GC31-MM model submission to the Coupled Model Intercomparison Project phase 6 (CMIP6). doi:10.22033/ESGF/CMIP6.1902

Sea ice is important to global climate because it reflects sunlight, insulates the ocean, and drives cold, salty water into the deep oceans.

What is the problem?

Climate models, which are our best tools for making projections of future climate, have failed to reproduce the observed trends in Antarctic sea ice. From 1979-2015 models showed declining Antarctic sea ice area, which didn’t match the slight increase observed from satellites. There have been different explanations for the discrepancy, for example, that current climate models do not represent the changing amount of land ice in the Antarctic ice sheet.

In the real world, Antarctica is losing mass over time, and as current models do not take this into account, they exclude an important source of fresh water flowing into the Southern Ocean. It has been suggested that this missing fresh water plays an important role in sea ice trends. Additional fresh water near the ocean surface increases the density gradient between the surface and deeper water, inhibiting vertical transport of relatively warm water from the depths, which results in surface cooling and warming of the deep ocean. This surface cooling then drives sea ice growth.

Our work as part of the Deep South National Science Challenge has been to investigate the effect of this missing fresh water on Antarctic sea ice trends in a state-of-the-art climate model.

Our work

We have been investigating the effect of missing fresh water from the Antarctic ice sheet on sea ice in the HadGEM3-GC3.1 climate model, which forms the physical core of the New Zealand Earth System Model.

We have run experiments with artificially added fresh water under pre-industrial control conditions and in a scenario where atmospheric CO₂ increases by 1% each year.

In both scenarios, adding the fresh water results in greater Antarctic sea ice area relative to the simulations that exclude it, and also results in a decline in Antarctic Bottom Water formation. We have tested the effect of adding fresh water as either melting icebergs or basal melt of the ice shelves, and found that while the responses are similar, there is greater ocean warming at depth when the fresh water is added to the model as basal melt.

We have also found that adding fresh water was able to offset ocean warming due to increased atmospheric CO₂ over the continental shelf in several regions around Antarctica. The magnitude of the effect depends on the specific continental shelf geometry, the climate state, and the vertical distribution of the fresh water.

Finally, we have been contributing simulations to an international model intercomparison that aims to better understand the reasons for inter-model differences in the response to the fresh water. We have conducted several of the model simulations outlined as part of the Southern Ocean Freshwater Input from Antarctica (SOFIA) initiative, and analysis and comparison to multiple other models from around the world has shown a large inter-model spread in the Antarctic sea ice and Southern Ocean temperature responses. This highlights the importance of this model intercomparison project for quantifying both the magnitude and uncertainty in the response to Antarctic meltwater.

What are the implications for Aotearoa New Zealand?

Impacts over land in New Zealand are small in our model simulations, but there is a significant reduction in warming of the ocean surface immediately to our southeast in both historical and future warming scenarios. Analysis of the impacts of this on moisture in the atmosphere and circulation are ongoing.

Climate change adaptation is often reduced to a question of monetary-based questions. Why did we let development happen in a risky area in the first place? How much would it cost to protect communities in place now, versus thinking in a longer-term way about where communities might feel and be safest?

But what happens when the most important things to us don’t have a price tag? How do we make sure the things we value most, our connections to whenua and tipuna, are properly factored into the decisions of governments and businesses?

With so much emphasis on the fiscal costs of adapting to climate change, or not adapting, we are losing important elements that should be included in that conversation.

Reframing the Costs of Climate Change

Work is underway across Aotearoa to quantify the costs of climate change, including the costs of adaptation or of failure to adapt. 

But how do we understand “cost” and will our economic paradigm really lead to effective climate adaptation? If we can’t or don’t quantify/consider some costs of climate change (and benefits of adaptation!), how can we ensure these are factored in our adaptation decisions? 

On the one hand, we need frameworks and tools that help us analyse our adaptation decisions (and indecisions). On the other, we need to consider the paradigm driving our current thinking, and the limits of current economic tools and frameworks to help us make collectively oriented, intergenerational decisions. 

Are we capable of making decisions that return to Papa and Rangi value greater than what we have taken?

What is a rolling symposium? 

This rolling symposium consists of preliminary podcasts, culminating in an all-day event, to generate evidence-based conversation around the economics of  adapting to climate change. In order to build towards an inspiring, productive and free-flowing conversation at our all-day event, we ask that you listen to each podcast wherever you get your podcasts (or catch up below, prior to the full day event).

Programme

We have now finalised our Ko Papa Ko Rangi programme. Please explore the full programme now, with some extraordinary keynotes and panelists and, of course, you!

As well as right here, you’ll find these podcasts wherever you get your podcasts! Be sure to subscribe for further content to be released down the track.

Podcast 1 | Ko Papa Ko Rangi, with Ruia Aperahama, Māni Dunlop and Alex Keeble

Listen here:

The first podcast in our rolling symposium is a conversation with the Pou Tikanga of the Deep South Challenge Ruia Aperahama, journalist Māni Dunlop and Deep South Challenge engagement team member Alex Keeble, exploring the symposium’s name.

Within mātauranga Māori, the concept of “utu” suggests that if something is taken, permission must first be requested. Once taken, something of equal or greater value must be returned. Further obligations are in this way generated, and a relationship becomes reciprocal. In the pūrākau of Papa and Rangi, for choosing to separate his parents, Tāne repays them over and again, with his heart forever to Papa and his feet always striving for Rangi – an expression of ever growing love. With this image, we see Tāne as upside down. But perhaps it is we who are the wrong way up? Are we capable of making decisions that return to Papa and Rangi value greater than what we have taken?

Podcast 2 | Ka mua ka muri, with Shaun Awatere, Jen Margaret and Māni Dunlop

Listen here:

To understand the paradigm within which we consider concepts of value, cost and risk, we need to grapple with our past and reconsider our present. In this second podcast, senior economist Shaun Awatere and Te Tiriti educator Jen Margaret look backwards and forwards, exploring how our economy and economic frameworks have evolved and been impacted by past decision-making, and what this could mean for our future with a changing climate.

Podcast 3 | Insurance for adaptation, with Ronji Tanielu, Carolyn Kousky, Belinda Storey and Kate Turner

Listen here:

How do we currently price, pay for and transfer “climate risk”? Are these methods reducing danger or delaying what we do about it? Insurance only works when you can afford it; who will be (or is being?) most harmed if we don’t support different ways of protecting ourselves and our communities? This third podcast, with experts from within and outside of the insurance industry, interrogate the role of insurance now, and what it might need to play an effective and equitable role in climate adaptation.

Podcast 4 | Framing the costs of climate change, with Sacha McMeeking, Anita Wreford, Jodie Kuntzsch and Kate Turner

Listen here:

Everyone, from homeowners to policy makers, from marae committees to corporations, is asking, “How much will climate change cost us, and how much will it cost to adapt?” But are these the best questions? 

Do we risk embedding an unbalanced future, because we’re struggling to step back and consider the full extent of what’s at stake? What would effective adaptation actually look and feel like?

This fourth and final podcast, with key thinkers in the space,  examines what we know about “costing climate change”, what we don’t know, and how we can inspire momentum for change throughout our government, businesses and communities.

10-11.10am | Panel: A wider lens: How do we conceptualise the costs of climate change?

We know that work is getting underway across Aotearoa to quantify the costs of climate change, including the costs of adaptation or of failure to adapt. But how do we understand “cost”? Does it encompass the fullness of our environmental, human, social, cultural (and financial) worlds that are central to our experiences of and response to this crisis. Can our current economic thinking really lead to effective climate adaptation? If we can’t or don’t consider some costs, how can we ensure these are factored in our adaptation decisions?

The Deep South Challenge is releasing the symposium report on our November 2023 conference, Adapting Aotearoa: Towards a climate resilient land and food system.

This event took place in Christchurch over two days, and saw participants across the agriculture, farming and food production sectors, meet and kōrero with academics and other professionals, to explore innovative solutions for building climate resilience and a deeper understanding of the urgency for adaptation in our agricultural practices.

We were privileged during the conference to hear from veteran journalist and climate change thinker Rod Oram, who tragically died this year (2024). Sessions from the conference were recorded, and are now available. They include Rod’s key note, and our two expert panels.

Our symposium report includes a dedication to Rod Oram.

Story by Nadine Anne Hura (via The Spinoff)

The Deep South Challenge is producing a podcast that will capture the stories of some of the researchers and communities working in our Vision Mātauranga programme. Our Kaitakawaenga Nadine has been travelling the country, listening to their kōrero. [READ on thespinoff.co.nz]

There’s a kind of awe that hits you when you understand the scale of the loss and the commitment required to heal and recover.

Yet, over and over again, people I spoke to reiterated that hope on its own isn’t the thing keeping them going. “Hope is abstract,” Shirley Simmonds of Ngāti Huri told me. She has recently made the move home to Pikitū with her whānau and is deeply attached to the shovel with which she’s she’s helped to plant the beginnings of a food forest, and also tree seedlings on land that was once – and will eventually again be – blanketed in native ngahere. “Hope needs to be activated through work,” Simmonds said. “Sovereignty is inherently practical. The solutions are within us – kei a tātou te rongoā.”

The podcast will be available in March 2024, co-hosted by Ruia Aperahama.

Adapting Aotearoa: Towards a climate resilient land and food system

Brought to you by the Deep South Challenge in collaboration with Resilience to Nature’s Challenges and Our Land and Water, this unique event brings together researchers and stakeholders from the primary sector, academia and government to explore innovative solutions for building climate resilience and deeper understanding of the urgency for adaptation in our agricultural practices.
