Anything worth achieving is hard. It requires dedication, focus, and perseverance. And sometimes a little luck. Osprey Wilds’ clean energy focus began 20 years ago. Yet, it wasn’t until this fall with the addition of a 716 kilowatt (kW) solar photovoltaic system that we finally reached our goal of producing 100% of our electricity on-site through renewable sources. As a 501 (c) (3) nonprofit environmental learning center, Osprey Wilds reaches over 15,000 people annually through our wide-ranging accredited environmental education programs. Located on Grindstone Lake, near Sandstone, MN, our campus resides on 783 acres of beautiful forests, prairies and wetlands. This ideal setting, accompanied by our overnight lodging and dining facilities, allows us to connect K-12 students, youth, family and adults to nature for multiple days at a time, providing truly immersive, meaningful connections to the environment. At our core, we believe it is our responsibility to model sustainable environmental practices for others to learn from. This includes how we steward the land, how we use energy, how we grow, raise and purchase food, and the products we use. Our goal is always trying to reduce our impact on the planet, lessen our carbon footprint, and teach our audience what they can do in turn with their lives. We strive to create environmental ripple marks and we achieve that through our mission of instilling a connection and commitment to the environment in people of all communities through experiential learning.

The path down our clean energy focus began in 2004, when we secured a federal Housing & Urban Development (HUD) grant to install a 65-ton geothermal ground-source heat pump system to cool and heat our two main buildings. This eliminated our usage of propane to heat the two buildings, and shifted our energy needs to run the heat pumps on electricity. With the realization that our overall energy usage was lower, but our electricity needs were now higher, we sought out adding renewable energy sources to produce the electricity we used. From 2005 to 2015, we were successful in obtaining grants to add over 39 kilowatts of solar photovoltaic arrays to supply about 20% of our total campus electricity needs. During that time, we also added 29 solar hot water panels for domestic use in heating the water used for our dormitory showers and sinks, and our commercial kitchen, made a campus-wide LED lighting upgrade, added blown cellulose insulation to improve the R-value of our buildings, and upgraded our HVAC control systems. But to cover the remaining 300,000 kilowatt hours of electricity we were still using annually, we knew we needed to do something big to achieve our goals of becoming carbon neutral.

In 2019, we reached out to a solar company to help us achieve that goal. Over the next several months, I worked with them on a plan of adding 248 kW of solar photovoltaic arrays, distributed across multiple solar-compatible locations on our property that would produce the kilowatts needed to cover our annual energy usage. We worked with our local bank to secure terms for a loan that would finance the cost of the system, and met with our local electric cooperative East Central Energy about how this could work. This proposed system would put us well over 40 kW on our account, the kW threshold in Minnesota for net-metering. Coming to the realization that this proposal wouldn’t allow for net metering with our system meant ultimately it wouldn’t work economically for Osprey Wilds, as we would have been reliant on the net-metered income for the months we overproduced to cover the loan expenses we were looking to take on to finance the project. If we could have purchased the system outright and not had to worry about cash flowing the loan, net metering wouldn’t have made a big difference. It was a learning process, and whetted my appetite to see if there was some other way we could collaborate with East Central Energy to achieve our energy goals and theirs.

We all know what happened in March 2020. The world came to a halt with the impact of COVID-19, and in many ways is forever changed from that pandemic. Our focus at Osprey Wilds shifted to institutional survival and how we could sustain as an organization that is designed around immersive, shared experiences with people. For a solid year, we had no program revenue from in-person K-12 schools, a devastating loss for us, only enhanced by the sadness in knowing that thousands of children looking forward to that multi-day nature experience at Osprey Wilds were missing out. We were fortunate to secure federal grants from the rescue packages passed, and stayed afloat. As things slowly began coming back and operations returned closer to normal, the time was right to re-engage with East Central Energy and their CEO Justin Jahnz to see what might be possible. Those talks in 2022 led to an idea – a three party power purchase agreement among Osprey Wilds, East Central Energy and a solar provider, with the solar provider owning and operating the system on Osprey Wilds property and selling the electricity to East Central Energy, who then would sell it to Osprey Wilds. For it to work, we needed a solar provider interested, selling the solar electricity generated at rates that would be make financial sense for East Central Energy to purchase, while still being high enough that it was profitable for the solar provider, yet also low enough that Osprey Wilds could afford to purchase the electricity from East Central Energy. It was a proposal that would require threading a needle to find financial terms that could work for all parties, but it was also exciting and definitely worth the effort to see if we could make it happen.

During this time period, Osprey Wilds also completed a conservation easement with the Minnesota Land Trust on over 460 acres of our campus. Permanently protecting over 85% of our campus was something our organization was proud to have accomplished, and aligned very strongly with our environmental values of treading lightly on the planet, and protecting natural resources in perpetuity. During this conservation easement process, I knew I wanted to leave open the ability to add a large solar photovoltaic system on our campus for the eventual goal of producing 100% of our electricity onsite. For an optimal solar capacity location, as well as a visually strong first impression, we landed on a 3-acre exclusion in our 20-acre tallgrass prairie, noticeable on your left hand side as soon as you pull into Osprey Wilds’ driveway. The 3-acre exclusion was large enough for a 250 kW system, capable of supplying all of our electricity needs.

But as we began working with East Central Energy on the RFP (request for proposal) for the solar project at Osprey Wilds, I learned that this was a relatively small space to work with, as providers would be interested in putting up a larger system to reach the economies of scale necessary to lower the cost of the project and make it financially attractive. Examining the size of the exclusion, it was determined that the largest a system could be was approximately 700 kW. While this seemed very large to me, many commercial solar installers are looking at systems with production levels two to ten times that size to make projects financially viable.

With that knowledge, I was worried if we would get any proposals that would fit within the financial parameters needed for it to work for East Central Energy and Osprey Wilds. In the spring of 2023, we received proposals back from multiple solar companies. But unfortunately and somewhat predictably, all the numbers were far higher than what East Central Energy could afford to purchase, and in turn, what Osprey Wilds could as well. With that deflating realization, we talked openly with the company that had been the closest in their proposal, Soltek, Inc., about our desire to find a way with this project. We shared the benefits we saw for their company to be able to partner with East Central Energy and an environmental learning center that hosts and educates thousands of participants each year, and the impact they could have on those individuals with this inspiring project. Shawn Markham, Soltek’s CEO, took that passion of ours to heart, and over the ensuing months kept diligently trying to find ways to reduce the cost of the project to make it viable.

In March of 2024, I got a message from Shawn that we should talk. Conditions had shifted dramatically within the solar industry in the past 12 months. Changes made by the California Public Utilities Commission (CPUC) in the fall of 2023 were taking effect April 15th that were reducing the daytime compensation for rooftop solar for homeowners by about 75%, making it much less affordable for individuals to add solar. As a result, the solar industry was struggling. Shawn now had access to materials and equipment that he could get for half the price he could a year ago, dramatically lowering the cost of the proposed Osprey Wilds system and thus lowering the rate at which he could sell electricity to East Central Energy. Concurrently, he had also applied for a Renewable Energy in America Program (REAP) grant through the USDA and was awaiting word on its status. By the end of June, Shawn got word that he’d received the REAP grant, and with the savings he was realizing with the lower priced materials for the project, he could offer a rate that fit for East Central Energy and their cooperative members, and for Osprey Wilds. The solar dream was going to happen!

Soon materials and panels were being delivered to Osprey Wilds, and all three parties worked on crafting power purchase and land lease agreements for project terms to become official. The end result would be a win-win-win. Soltek would own and operate the system, selling affordable electricity to East Central Energy, while creating a 30-year source of guaranteed income. East Central Energy would expand their ability to purchase affordable, clean, and locally sourced electricity for their members. Lastly, Osprey Wilds would achieve its carbon goals, and save money with favorable electricity rates secured for the next 30 years.

Installation of the eventual 716 kW prairie solar garden began late July and was completed in just three weeks. East Central Energy is currently in the final stages of installing their transfer station next to the system, which will feed into their phase three line only a few hundred feet away. The system will go live in October, and produce 1,000,000 kWh (1,000 megawatt hours) annually, more than three times Osprey Wilds’ current electricity demands. The large production level of the system will set us up for future campus expansions that can remain carbon neutral. In the meantime, the majority of the electricity generated will actually go to our neighbors, providing them with clean, locally produced electricity at no increased expense to them.

The prairie solar garden is nestled within prairie grasses and wildflowers, allowing native ecosystems to coincide with energy production. In addition, the solar garden is bordered by a woven wire fence perimeter, which will allow us to partner with local sheep producers to add pastured livestock and agriculture into the mix, creating three sustainable land uses simultaneously.

With this project’s completion, we will now boast the largest solar photovoltaic system of any nature center or environmental learning center in Minnesota and the Midwest. It is a tangible example of what can happen when you work with others – you are able to achieve something greater than you could on your own. A rising tide lifts all boats, and it is our hope that this project demonstrates to our guests our commitment to the planet, and that it inspires them to pursue ways they can reduce their carbon footprint and climate change impact. We share a beautiful planet, one of unimaginable beauty, that is worth fighting for. When you love something, you take care of it, and at Osprey Wilds, this prairie solar garden is our latest pledge to the Earth that we are doing what we can to take care of it. We encourage you to do what you can for the planet as well.

Osprey Wilds is open to the public with over 10 miles of hiking and cross country ski trails at no charge. Visit us to see our prairie solar garden, check out our live animal ambassadors, shop our gift shop, learn about upcoming programs,  or simply enjoy a nature respite along the lake, in the woods, or on the prairie.

The 2026 budget test: Will Australia break free from fossil fuels?

Published

on

In 2026, the dangers of fossil fuel dependence have been laid bare like never before. The illegal invasion of Iran has brought pain and destruction to millions across the Middle East and triggered a global energy crisis impacting us all. Communities in the Pacific have been hit especially hard by rising fuel prices, and Australians have seen their cost-of-living woes deepen.

Such moments of crisis and upheaval can lead to positive transformation. But only when leaders act with courage and foresight.

There is no clearer statement of a government’s plans and priorities for the nation than its budget — how it plans to raise money, and what services, communities, and industries it will invest in.

As we count down the days to the 2026-27 Federal Budget, will the Albanese Government deliver a budget for our times? One that starts breaking the shackles of fossil fuels, accelerates the shift to clean energy, protects nature, and sees us work together with other countries towards a safer future for all? Or one that doubles down on coal and gas, locks in more climate chaos, and keeps us beholden to the whims of tyrants and billionaires.

Here’s what we think the moment demands, and what we’ll be looking out for when Treasurer Jim Chalmers steps up to the dispatch box on 12 May.

1. Stop fuelling the fire
2. Make big polluters pay
3. Support everyone to be part of the solution
4. Build the industries of the future
5. Build community resilience
6. Be a better neighbour
7. Protect nature

1. Stop fuelling the fire

In mid-April, Pacific governments and civil society met to redouble their efforts towards a Fossil Fuel Free Pacific. Moving beyond coal, oil and gas is fundamental to limiting warming to 1.5°C — a survival line for vulnerable communities and ecosystems. And as our Head of Pacific, Shiva Gounden, explained, it is “also a path of liberation that frees us from expensive, extractive and polluting fossil fuel imports and uplifts our communities”.

Pacific countries are at the forefront of growing global momentum towards a just transition away from fossil fuels, and it is way past time for Australia to get with the program. It is no longer a question of whether fossil fuel extraction will end, but whether that end will be appropriately managed and see communities supported through the transition, or whether it will be chaotic and disruptive.

So will this budget support the transition away from fossil fuels, or will it continue to prop up coal and gas?

When it comes to sensible moves the government can make right now, one stands out as a genuine low hanging fruit. Mining companies get a full rebate of the excise (or tax) that the rest of us pay on diesel fuel. This lowers their operating costs and acts as a large, ongoing subsidy on fossil fuel production — to the tune of $11 billion a year!

Greenpeace has long called for coal and gas companies to be removed from this outdated scheme, and for the billions in savings to be used to support the clean energy transition and to assist communities with adapting to the impacts of climate change. Will we see the government finally make this long overdue change, or will it once again cave to the fossil fuel lobby?

2. Make big polluters pay

While our communities continue to suffer the escalating costs of climate-fuelled disasters, our Government continues to support a massive expansion of Australia’s export gas industry. Gas is a dangerous fossil fuel, with every tonne of Australian gas adding to the global heating that endangers us all.

Moreover, companies like Santos and Woodside pay very little tax for the privilege of digging up and selling Australians’ natural endowment of fossil gas. Remarkably, the Government currently raises more tax from beer than from the Petroleum Resource Rent Tax (PRRT) — the main tax on gas profits.

Momentum has been building to replace or supplement the PRRT with a 25% tax on gas exports. This could raise up to $17 billion a year — funds that, like savings from removing the diesel tax rebate for coal and gas companies, could be spent on supporting the clean energy transition and assisting communities with adapting to worsening fires, floods, heatwaves and other impacts of climate change.

As politicians arrive in Canberra for budget week, they will be confronted by billboards calling for a fair tax on gas exports. The push now has the support of dozens of organisations and a growing number of politicians. Let’s hope the Treasurer seizes this rare window for reform.

3. Support everyone to be part of the solution

As the price of petrol and diesel rises, electric vehicles (EVs) are helping people cut fuel use and save money. However, while EV sales have jumped since the invasion of Iran sent fuel prices rising, they still only make up a fraction of total new car sales. This budget should help more Australians switch to electric vehicles and, even more importantly, enable more Australians to get around by bike, on foot, and on public transport. This means maintaining the EV discount, investing in public and active transport, and removing tax breaks for fuel-hungry utes and vans.

Millions of Australians already enjoy the cost-saving benefits of rooftop solar, batteries, and getting off gas. This budget should enable more households, and in particular those on lower incomes, to access these benefits. This means maintaining the Cheaper Home Batteries Program, and building on the Household Energy Upgrades Fund.

4. Build the industries of the future

If we’re to transition away from fossil fuels, we need to be building the clean industries of the future.

No state is more pivotal to Australia’s energy and industrial transformation than Western Australia. The state has unrivaled potential for renewable energy development and for replacing fossil fuel exports with clean exports like green iron. Such industries offer Western Australia the promise of a vibrant economic future, and for Australia to play an outsized positive role in the world’s efforts to reduce emissions.

However, realising this potential will require focussed support from the Federal Government. Among other measures, Greenpeace has recommended establishing the Australasian Green Iron Corporation as a joint venture between the Australian and Western Australian governments, a key trading partner, a major iron ore miner and steel makers. This would unite these central players around the complex task of building a large-scale green iron industry, and unleash Western Australia’s potential as a green industrial powerhouse.

5. Build community resilience

Believe it or not, our Government continues to spend far more on subsidising fossil fuel production — and on clearing up after climate-fuelled disasters — than it does on helping communities and industries reduce disaster costs through practical, proven methods for building their resilience.

Last year, the Government estimated that the cost of recovery from disasters like the devastating 2022 east coast floods on 2019-20 fires will rise to $13.5 billion. For contrast, the Government’s Disaster Ready Fund – the main national source of funding for disaster resilience – invests just $200 million a year in grants to support disaster preparedness and resilience building. This is despite the Government’s own National Emergency Management Agency (NEMA) estimating that for every dollar spent on disaster risk reduction, there is a $9.60 return on investment.

By redirecting funds currently spent on subsidising fossil fuel production, the Government can both stop incentivising climate destruction in the first place, and ensure that Australian communities and industries are better protected from worsening climate extremes.

No communities have more to lose from climate damage, or carry more knowledge of practical solutions, than Aboriginal and Torres Strait Islander peoples. The budget should include a dedicated First Nations climate adaptation fund, ensuring First Nations communities can develop solutions on their own terms, and access the support they need with adapting to extreme heat, coastal erosion and other escalating challenges.

6. Be a better neighbour

The global response to climate change depends on the adequate flow of support from developed economies like Australia to lower income nations with shifting to clean energy, adapting to the impacts of climate change, and addressing loss and damage.

Such support is vital to building trust and cooperation, reducing global emissions, and supporting regional and global security by enabling countries to transition away from fossil fuels and build greater resilience.

Despite its central leadership role in this year’s global climate negotiations, our Government is yet to announce its contribution to international climate finance for 2025-2030. Greenpeace recommends a commitment of $11 billion for this five year period, which is aligned with the global goal under the Paris Agreement to triple international climate finance from current levels.
This new commitment should include additional funding to address loss and damage from climate change and a substantial contribution to the Pacific Resilience Facility, ensuring support is accessible to countries and communities that need it most. It should also see Australia get firmly behind the vision of a Fossil Fuel Free Pacific.

7. Protect nature

There is no safe planet without protection of the ecosystems and biodiversity that sustain us and regulate our climate.

Last year the Parliament passed important and long overdue reforms to our national environment laws to ensure better protection for our forests and other critical ecosystems. However, the Government will need to provide sufficient funding to ensure the effective implementation of these reforms.

Greenpeace has recommended $500 million over four years to establish the National Environment Agency — the body responsible for enforcing and monitoring the new laws — and a further $50 million to Environment Information Australia for providing critical information and tools.

Further resourcing will also be required to fulfil the crucial goal of fully protecting 30% of Australian land and seas by 2030. This should include $1 billion towards ending deforestation by enabling farmers and loggers to retool away from destructive practices, $2 billion a year for restoring degraded lands, $5 billion for purchasing and creating new protected areas, and $200 million for expanding domestic and international marine protected areas.

Conclusion

This is not the first time that conflict overseas has triggered an energy crisis, or that a budget has been preceded by a summer of extreme weather disasters, highlighting the urgent need to phase out fossil fuels. What’s different in 2026 is the availability of solutions. Renewable energy is now cheaper and more accessible than ever before. Global momentum is firmly behind the transition away from fossil fuels. The Albanese Government, with its overwhelming majority, has the chance to set our nation up for the future, or keep us stranded in the past. Let’s hope it makes some smart choices.

What fossil fuels really cost us in a world at war

Published

on

Anne Jellema is Executive Director of 350.org.

The war on Iran and Lebanon is a deeply unjust and devastating conflict, killing civilians at home, destroying lives, and at the same time sending shockwaves through the global economy. We, at 350.org, have calculated, drawing on price forecasts from the International Monetary Fund (IMF) and Goldman Sachs, just how much that volatility is costing us. 

Even under the IMF’s baseline scenario – a de facto “best case” scenario with a near-term end to the war and related supply chain disruptions – oil and gas price spikes are projected to cost households and businesses globally more than $600 billion by the end of the year. Under the IMF’s “adverse scenario”, with prolonged conflict and sustained price pressures, we estimate those additional costs could exceed $1 trillion, even after accounting for reduced demand.

Which is why we urgently need a power shift. Governments are under growing pressure to respond to rising fuel and food costs and deepening energy poverty. And it’s becoming clearer to both voters and elected officials that fossil dependence is not only expensive and risky, but unnecessary. 

People who can are voting with their wallets: sales of solar panels and electric vehicles are increasing sharply in many countries. But the working people who have nothing to spare, ironically, are the ones stuck with using oil and gas that is either exorbitantly expensive or simply impossible to get.

Drain on households and economies

In India, street food vendors can’t get cooking gas and in the Philippines, fishermen can’t afford to take their boats to sea. A quarter of British people say that rising energy tariffs will leave them completely unable to pay their bills. This is the moment for a global push to bring abundant and affordable clean energy to all.

In April, we released Out of Pocket, our new research report on how fossil fuels are draining households and economies. We were surprised by the scale of what we found. For decades, governments have reassured people that energy price spikes are unfortunate but unavoidable – the result of distant conflicts, market forces or geopolitical shocks beyond anyone’s control. But the numbers tell a different story. 

    What we are living through today is not an energy crisis. It is a fossil fuel crisis. In just the first 50 days of the Middle East conflict, soaring oil and gas prices have siphoned an estimated $158 billion–$166 billion from households and businesses worldwide. That is money extracted directly from people’s pockets and transferred, almost instantly, into fossil fuel company balance sheets. And this figure only captures the immediate impact of price spikes, not the permanent economic drain of fossil dependence. Fossil fuels don’t just cost us once, they cost us over and over again.

    First, through our bills. Every time there is a war, an embargo or a supply disruption, fossil fuel prices surge. For ordinary people, this means higher costs for energy, transport and food. Many Global South countries have little or no fiscal space to buffer the shock; instead, workers and families pay the price.

    Second, through our taxes. Governments around the world continue to pour vast sums of public money into fossil fuel subsidies. These are often justified as a way to protect the most vulnerable at the petrol pump or in their homes. But in reality, the benefits are overwhelmingly captured by wealthier households and corporations. The poorest 20% receive just a fraction of this support, while public finances are drained.

    Third, through climate impacts. New research across more than 24,000 global locations gives a granular account of the true costs of extreme heat, sea level rise and falling agricultural yields. Using this data to update IMF modelling of the social cost of carbon, we found that fossil fuel impacts on health and livelihoods amount to over $9 trillion a year. This is the biggest subsidy of all, because these massive and mounting costs are not charged to Big Oil – they are paid for by governments and households, with the poorest shouldering the lion’s share. 

    Massive transfer of wealth to fossil fuel industry

    Adding up direct subsidies, tax breaks and the unpaid bill for climate damages, the total transfer of wealth from the public to the fossil fuel industry amounts to $12 trillion even in a “normal” year without a global oil shock. That’s more than 50% higher than the IMF has previously estimated, and equivalent to a staggering $23 million a minute.

    The fossil fuel industry has become extraordinarily adept at profiting from instability. When conflict drives up prices, companies do not lose, they gain. In the current crisis, oil producers and commodity traders are on track to secure tens of billions of dollars in additional windfall profits, even as households face rising bills and governments struggle to manage the fallout.

    Fossil fuel crisis offers chance to speed up energy transition, ministers say

    This growing disconnect is impossible to ignore. Investors are advised to buy into fossil fuel firms precisely because of their ability to generate profits in times of crisis. Meanwhile, ordinary people are told to tighten their belts.

    In 2026, unlike during the oil shocks of the 1970s, clean energy is no longer a distant alternative. Now, even more than when gas prices spiked due to Russia’s invasion of Ukraine in 2022, renewables are often the cheapest option available. Solar and wind can be deployed quickly, at scale, and without the volatility that defines fossil fuel markets.

    How to transition from dirty to clean energy

    The solutions are clear. Governments must implement permanent windfall taxes on fossil fuel companies to ensure that extraordinary profits generated during crises are redirected to support households. These revenues can be used to reduce energy bills, invest in public services, and accelerate the rollout of clean energy.

    Second, we must shift subsidies away from fossil fuels and towards renewable solutions, particularly those that can be deployed quickly and equitably, such as rooftop and community solar. This is not just about cutting emissions. It is about building a more stable, fair and resilient energy system.

    Finally, we need binding plans to phase out fossil fuels altogether, replacing them with homegrown renewable energy that can shield economies from future shocks. Because what the current crisis has made clear is this: as long as we remain dependent on fossil fuels, we remain vulnerable – to conflict, to price volatility and to the escalating impacts of climate change.

    The true price of fossil fuels is no longer hidden. It is visible in rising bills, strained public finances and communities pushed to the brink. And it is being paid, every day, by ordinary people around the world.

    It’s time for the great power shift

    Traditional models still ‘outperform AI’ for extreme weather forecasts

    Published

    on

    Computer models that use artificial intelligence (AI) cannot forecast record-breaking weather as well as traditional climate models, according to a new study.

    It is well established that AI climate models have surpassed traditional, physics-based climate models for some aspects of weather forecasting.

    However, new research published in Science Advances finds that AI models still “underperform” in forecasting record-breaking extreme weather events.

    The authors tested how well both AI and traditional weather models could simulate thousands of record-breaking hot, cold and windy events that were recorded in 2018 and 2020.

    They find that AI models underestimate both the frequency and intensity of record-breaking events.

    A study author tells Carbon Brief that the analysis is a “warning shot” against replacing traditional models with AI models for weather forecasting “too quickly”.

    AI weather forecasts

    Extreme weather events, such as floods, heatwaves and storms, drive hundreds of billions of dollars in damages every year through the destruction of cropland, impacts on infrastructure and the loss of human life.

    Many governments have developed early warning systems to prepare the general public and mobilise disaster response teams for imminent extreme weather events. These systems have been shown to minimise damages and save lives.

    For decades, scientists have used numerical weather prediction models to simulate the weather days, or weeks, in advance.

    These models rely on a series of complex equations that reproduce processes in the atmosphere and ocean. The equations are rooted in fundamental laws of physics, based on decades of research by climate scientists. As a result, these models are referred to as “physics-based” models.

    However, AI-based climate models are gaining popularity as an alternative for weather forecasting.

    Instead of using physics, these models use a statistical approach. Scientists present AI models with a large batch of historical weather data, known as training data, which teaches the model to recognise patterns and make predictions.

    To produce a new forecast, the AI model draws on this bank of knowledge and follows the patterns that it knows.

    There are many advantages to AI weather forecasts. For example, they use less computing power than physics-based models, because they do not have to run thousands of mathematical equations.

    Furthermore, many AI models have been found to perform better than traditional physics-based models at weather forecasts.

    However, these models also have drawbacks.

    Study author Prof Sebastian Engelke, a professor at the research institute for statistics and information science at the University of Geneva, tells Carbon Brief that AI models “depend strongly on the training data” and are “relatively constrained to the range of this dataset”.

    In other words, AI models struggle to simulate brand new weather patterns, instead tending forecast events of a similar strength to those seen before. As a result, it is unclear whether AI models can simulate unprecedented, record-breaking extreme events that, by definition, have never been seen before.

    Record-breaking extremes

    Extreme weather events are becoming more intense and frequent as the climate warms. Record-shattering extremes – those that break existing records by large margins – are also becoming more regular.

    For example, during a 2021 heatwave in north-western US and Canada, local temperature records were broken by up to 5C. According to one study, the heatwave would have been “impossible” without human-caused climate change.

    The new study explores how accurately AI and physics-based models can forecast such record-breaking extremes.

    First, the authors identified every heat, cold and wind event in 2018 and 2020 that broke a record previously set between 1979 and 2017. (They chose these years due to data availability.) The authors use ERA5 reanalysis data to identify these records.

    This produced a large sample size of record-breaking events. For the year 2020, the authors identified around 160,000 heat, 33,000 cold and 53,000 wind records, spread across different seasons and world regions.

    For their traditional, physics-based model, the authors selected the High RESolution forecast model from the Integrated Forecasting System of the European Centre for Medium-­Range Weather Forecasts. This is “widely considered as the leading physics-­based numerical weather prediction model”, according to the paper.

    They also selected three “leading” AI weather models – the GraphCast model from Google Deepmind, Pangu-­Weather developed by Huawei Cloud and the Fuxi model, developed by a team from Shanghai.

    The authors then assessed how accurately each model could forecast the extremes observed in the year 2020.

    Dr Zhongwei Zhang is the lead author on the study and a researcher at Karlsruhe Institute of Technology. He tells Carbon Brief that many AI weather forecast models were built for “general weather conditions”, as they use all historical weather data to train the models. Meanwhile, forecasting extremes is considered a “secondary task” by the models.

    The authors explored a range of different “lead times” – in other words, how far into the future the model is forecasting. For example, a lead time of two days could mean the model uses the weather conditions at midnight on 1 January to simulate weather conditions at midnight on 3 January.

    The plot below shows how accurately the models forecasted all extreme events (left) and heat extremes (right) under different lead times. This is measured using “root mean square error” – a metric of how accurate a model is, where a lower value indicates lower error and higher accuracy.

    The chart on the left shows how two of the AI models (blue and green) performed better than the physics-based model (black) when forecasting all weather across the year 2020.

    However, the chart on the right illustrates how the physics-based model (black) performed better than all three AI models (blue, red and green) when it came to forecasting heat extremes.

    The authors note that the performance gap between AI and physics-based models is widest for lower lead times, indicating that AI models have greater difficulty making predictions in the near future.

    They find similar results for cold and wind records.

    In addition, the authors find that AI models generally “underpredict” temperature during heat records and “overpredict” during cold records.

    The study finds that the larger the margin that the record is broken by, the less well the AI model predicts the intensity of the event.

    ‘Warning shot’

    Study author Prof Erich Fischer is a climate scientist at ETH Zurich and a Carbon Brief contributing editor. He tells Carbon Brief that the result is “not unexpected”.

    He adds that the analysis is a “warning shot” against replacing traditional models with AI models for weather forecasting “too quickly”.

    The analysis, he continues, is a “warning shot” against replacing traditional models with AI models for weather forecasting “too quickly”.

    AI models are likely to continue to improve, but scientists should “not yet” fully replace traditional forecasting models with AI ones, according to Fischer.

    He explains that accurate forecasts are “most needed” in the runup to potential record-breaking extremes, because they are the trigger for early warning systems that help minimise damages caused by extreme weather.

    Leonardo Olivetti is a PhD student at Uppsala University, who has published work on AI weather forecasting and was not involved in the study.

    He tells Carbon Brief that “many other studies” have identified issues with using AI models for “extremes”, but this paper is novel for its specific focus on extremes.

    Olivetti notes that AI models are already used alongside physics-based models at “some of the major weather forecasting centres around the world”. However, the study results suggest “caution against relying too heavily on these [AI] models”, he says.

    Prof Martin Schultz, a professor in computational earth system science at the University of Cologne who was not involved in the study, tells Carbon Brief that the results of the analysis are “very interesting, but not too surprising”.

    He adds that the study “justifies the continued use of classical numerical weather models in operational forecasts, in spite of their tremendous computational costs”.

    Advances in forecasting

    The field of AI weather forecasting is evolving rapidly.

    Olivetti notes that the three AI models tested in the study are an “older generation” of AI models. In the last two years, newer “probabilistic” forecast models have emerged that “claim to better capture extremes”, he explains.

    The three AI models used in the analysis are “deterministic”, meaning that they only simulate one possible future outcome.

    In contrast, study author Engelke tells Carbon Brief that probabilistic models “create several possible future states of the weather” and are therefore more likely to capture record-breaking extremes.

    Engelke says it is “important” to evaluate the newer generation of models for their ability to forecast weather extremes.

    He adds that this paper has set out a “protocol” for testing the ability of AI models to predict unprecedented extreme events, which he hopes other researchers will go on to use.

    The study says that another “promising direction” for future research is to develop models that combine aspects of traditional, physics-based weather forecasts with AI models.

    Engelke says this approach would be “best of both worlds”, as it would combine the ability of physics-based models to simulate record-breaking weather with the computational efficiency of AI models.

    Dr Kyle Hilburn, a research scientist at Colorado State University, notes that the study does not address extreme rainfall, which he says “presents challenges for both modelling and observing”. This, he says, is an “important” area for future research.
