NARCliM2.0 climate stripes. The observed and projected annual average temperature in NSW, visualises the future we must avoid.
The Projections
Compared to a baseline climate for the period between 1990-2009, NSW is expected to experience average warming of 1.2°C by 2050, and 1.3°C by 2090 in the low-emissions scenario, and warming of 2°C by 2050, and 4°C by 2090 in the high-emissions scenario. The significant difference between these futures reminds us of the importance of local and global efforts to reduce greenhouse emissions and reach Net-Zero by 2050.
Overall, increased warming will lead to
In translating the climate projections, it is important to consider the historical changes before the 1990-2009 baseline.
For example, our national temperature observations indicate NSW has warmed by 0.84°C between 1910-1930 and the baseline period. The 1990-2009 baseline period was selected to be consistent with previous generations of NARCliM (1.0, 1.5).

NARCliM2.0 projections provide detailed insights into how NSW communities, built and natural environments will continue to be impacted under future climate change. This information can be used to assess risk and take action to reduce the impacts of climate change.
How are government agencies using NARCliM?
Since the first generation of NARCliM was released in 2014, it has become the ‘go to’ source of climate information for government agencies in NSW. Leveraging the experience of a selection of our end-users, we have captured learnings and insights in a suite of case studies. Building on this, we also have available a series of video case studies that highlight the journey of end-users across sectors as they work towards effectively applying the NARCliM data for a range of climate adaptation planning.
Climate change creates a significant risk to infrastructure, people, and the economy. The impacts from climate change, including damaging weather events, has already cost the state an estimated $3.6 billion per year.
The role of the Greater Cities Commission is to coordinate and align the planning that will shape the future of the Six Cities Region.
NSW councils are building climate risk into their business-as-usual planning and policies for the first time, thanks to products developed using NARCliM’s locally relevant climate model data.

Many enterprises across the country are already considering the potential impacts of climate change on business, and adjusting their strategy. From supply chain resilience to operational efficiency and continuity planning, every decision should be backed by an understanding of climate risks and opportunities. NARCliM2.0 data can help you with just that – as well as support climate reporting.
Use the interactive climate change projections map and My Region pages to understand physical climate risk, and check out our How to Adapt page for Business.

Aboriginal people are the first Astronomers, Scientists and Adaptation specialists.
Australia’s First Nations people have lived in NSW for over 60,000 years and have significant spiritual, cultural and economic connections with its lands, waters, seas and skies. They are the first astronomers and scientists who have been listening to and caring for Country for generations.
In spring 2023, 60 Worimi people, led by Aunty Michelle Perry, gathered for what is believed to be the first Community-led cultural burn in Barrington Tops since colonisation.
Climate change is a Dreaming story that we have co-created, Gamilaroi woman Paris Norton told the AdaptNSW 2022 Forum.
Aboriginal people have been using generational knowledge of land and sea management in response to changing climates over thousands of years.
NARCliM2.0 has adopted the latest global greenhouse gas emissions scenarios from the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report.
These include a low (SSP1-2.6) and high (SSP3-7.0) emissions scenario. Data for a third emissions scenario (SSP2-4.5) will be available in 2025.
The projections highlight the stark difference in climate change impacts that will be experienced between the low and high-emissions scenarios. This illustrates just how important it is to take action to reduce emissions.
Developing NARCliM2.0
To develop the next generation of NARCliM data, our climate scientists have drawn on the latest available science used in the IPCC Sixth Assessment Report.
NARCliM2.0 uses advanced regional climate modelling techniques, and global climate models and emissions scenarios from the latest Coupled Model Intercomparison Project - Phase 6 (CMIP6).
The development of NARCliM2.0 represents the most computationally intensive generation of NARCliM to date. NARCliM2.0 data have been through almost 3 years of processing thanks to a collaboration with Canberra’s National Computational Infrastructure, one of the Southern Hemisphere’s most powerful supercomputers.
Producing NARCliM data is an iterative process. There are 3 generations of NARCliM data available, NARCliM2.0 (2024), NARCliM1.5 (2020) and NARCliM1.0 (2014). Each generation responds to changing end-user needs and incorporates the latest available science.
The development of NARCliM data follows a rigorous process and procedure for creating scientifically robust, fit-for-purpose regional climate data.
NARCliM is the NSW Government’s recommended source of climate projections for NSW. Each generation of NARCliM contains multiple sets of projections, and it’s important to understand the differences between the generations and know which to use.
