    Decoder Replay: Can we prepare for unpredictable weather?

    There’s no denying climate change when a tornado rips through your town or a blizzard buries you in snow. So why blame the people who raise weather alarms?

  • Are you aware of your level of climate ignorance?

    Are you aware of your level of climate ignorance?

    Do you know which country emits the most greenhouse gases per capita? If not, you aren’t alone.

    I’m a student at The Climate Academy, an international organization founded by philosopher and climate activist Matthew Pye who teaches students about climate change from a systems point of view.

    This year, we surveyed almost 500 people in Brussels, Varese and Milan to analyse the level of climate literacy among populations across Europe. Many people we surveyed pointed at large emitters such as the United States, China and India.

    Yes, these are big emitters in quantity, but when it comes to per capita emissions — the amount divided by the population of the country — the top three are smaller, wealthy countries: Singapore, the United Arab Emirates and Belgium.

    These numbers can be explained by the extremely consumeristic, luxury lifestyle of the overwhelming majority of their citizens and the over-reliance on fossil fuels for generating energy. Yet, in our survey, 378 people out of 468 — 81% — named the United States, China or India.

    We must refocus the lens.

    What does this mean? That the media attention is on the wrong players. As stated by the World Economic Forum:

    “When India surpassed the European Union in total annual greenhouse gas (GHG) emissions in 2019 becoming the third largest emitting country after China and the United States, that statistic only told part of the story. India’s population is nearly three times larger than that of the EU, so based on emissions per person, India ranks much lower among the world’s national emitters.”

    It is crucial to look at per capita emissions. That’s the conclusion of the Global Change Data Lab, a nonprofit organization that produces Our World in Data. It argues that annual national emissions do not take population size into account.

    “All else being equal, we might expect that a country with more people would have higher emissions,” it reported. “Emissions per person are often seen as a fairer way of comparing. Historically — and as is still true in low- and middle-income countries today — CO2 emissions and incomes have been tightly coupled. That means that low per capita emissions have been an indicator of low incomes and high poverty levels.”

    Europe often points at big emitters, but the comfortable lifestyles Europeans have due to their higher living standards aren’t sustainable.

    Who to blame for climate change?

    There’s a misconception that the more a country emits, the more responsible the country is for climate change.

    This is the result of intense lobbying and voluntary misdirection by the richest. The wealthiest individuals are undoubtedly responsible for a considerably higher share of global emissions. But we’re often told that countries like China and India are the most responsible, as they are some of the world’s biggest polluters, a fact which is widely recognized.

    Pye said it isn’t a surprise that the focus is on numbers at the macro level, as international organizations like the United Nations were created by the main global powers and they are still funded mainly by them.

    “Keeping the language and the numbers about the problem general and global masks the fact that the majority of our [per capita] emissions are still from these rich nations,” he said. “This lack of clarity about who is responsible is reflected right across global media coverage. It is not by chance that we don’t have a clear view of the vital statistics, it is by subtle and powerful design.”

    The UN is founded on the principle of human rights, he said.

    “Should it not think and act on climate change with everyone having an equal right to the air?” Pye said. “When you look at per capita and consumption emissions the whole landscape of responsibility is radically different.”

    Surveying people about greenhouse gases

    I conducted my part of the survey in a middle-class neighborhood of Brussels.

    When I asked a 20-year-old, “What would the consequences of a two degree increase in global temperature be?” I got this answer: “More meteorites.” When I put the same question to someone 50 years of age, the answer was, “It’s going to be cold.”

    A 75-year old told me: “I don’t believe in climate change. There were examples of extreme heat in the 17th century, it is natural. Climate change is a tool of the government to control us.”

    All of these are misconceptions about weather events, temperature patterns and the source and type of climate change we experience.

    Now, this survey included only a small sample of the population. But it already shows that the misconceptions in education about climate change are real and existent across every generation and in many ways. Many other surveys made by reputable organizations have supported this conclusion.

    What people don’t know

    A 2010 report by the Yale University Program on Climate Change Education found that 63% of Americans believed that global warming was happening, but many did not understand why. In this assessment, only 8% of Americans had knowledge equivalent to an A or B, 40% would receive a C or D, and 52% would get an F.

    A report by King’s College in London, based on a 2019 survey, found a similar level of ignorance.

    Misconceptions are still here, waiting to be tackled. It starts in schools, where new, fresh generations without bias or misconceptions are formed. It starts at home, where parents should adapt and teach their kids the basics. Proper educational programs should be set up by governments.

    This seems natural. But just a few months ago, in the United States, the Trump administration cut funding for schools that hold educational programs on climate change and greenhouse gas emissions reduction.

    Educational systems, too, spread misconceptions about climate change. Because we never stop learning, educational systems shouldn’t have such flaws and should provide accurate information.

    As we dive deeper into the climate crisis, proper knowledge and understanding will be key to systemic change and governmental response.

    Until information on climate change becomes a public good, we will continue to “debate what kind of swimming costume we will wear as the tsunami comes.” Those are the words of then-U.S. Treasury Secretary Hank Paulson before the 2008 financial crisis.


    Questions to consider:

    1. Why is it important to consider the size of a population when considering responsibility for climate change?

    2. What is meant by “climate ignorance”?

    3. How can you learn more about climate change?

  • Climate change brings new worries to an old industry

    Climate change brings new worries to an old industry

    It is another early harvest for the Vignoble des Agaises, a vineyard in the region of Mons in Belgium. While the country is widely known for its variety of Trappist beers, the proximity that Mons and the region of Wallonia bears to French Burgundy and Picardie influences the local drinking culture. 

    Indeed, wine means a great deal to Arnaud Leroy, the vineyard’s sales manager. He and his family have, for 20 years now, pioneered the potential of the frontier that is Southern Belgium in the production of champagne and other sparkling wines. 

    Wine has been a staple of the regional economy and culture for centuries and has been a vital part of Leroy’s life and that of millions of other people around the world. Recently, however, a series of early frosts have decimated large quantities of the harvests in the lands stretching from Lombardy to Flanders. 

    These poor harvests have left many local vineyards in a state of financial uncertainty. Such events aren’t unique to the regions of Western Europe. Similar problems and hardships have been experienced in most other winemaking regions of Europe and have caused harm to winemaking communities around the world.

    Europe has been hit by what may only be compared to a “tidal wave” of change as previously predictable and constant meteorological conditions that have allowed winemaking to prosper in these regions for millennia have been altered significantly in the span of nearly a few decades.

    “In the last 10 years we have always harvested in October,” Leroy said. “But recent harvests have systematically been earlier and earlier into September, this year’s harvest being around the third of September.” This seemingly light change may have an outsized impact on the nature of the wine produced, deeply affecting the wine’s taste and composition.

    With wine, climate is everything.

    Wine is widely regarded as one of the most climate-sensitive crop cultures, experiencing possible changes to its texture, taste and tannin density from even the smallest constant meteorological change. 

    Earlier harvests can affect the wine’s taste, as a low maturation of the grapes may cause an increased sourness and a less sweet taste as well as a lighter, less-defined aroma, while spring frosts like the ones experienced in the last few years may cause the exact opposite, making a much sweeter, less-acidic and more tannin heavy wine. 

    Thus, the taste of many well-established sorts and brands of wines may be inconsistent and altered significantly by the seasonal changes brought by the climate crisis. Renowned regions such as Tuscany, Burgundy, Greece, the Rhine Valley, California and many more may be considerably different — and potentially even in danger of being displaced in a few decades.

    Indeed, it would seem one of Europe’s oldest industries is in a crisis. Wine has been a luxury product for thousands of years and holds a cultural, economic, social and historical value that few other comparable goods hold. 

    Associated with the higher class and nobility for centuries and being a valued good for over 10 millennia, wine is arguably one of Europe’s most important goods. It holds a vital place in Christian tradition and practice and — having two saints and a multitude of deities of hundreds of religions and mythologies — it is perhaps one of the most important components to the cultural development of the continent and perhaps, of the world.

    Addressing climate change

    The changes experienced in the last decades have not gone unnoticed. Many oenologists and vintners have called for more attention and action in the fight against climate change and the seasonal changes it may bring. What is now often called a crisis is even further fueled by other external causes.

    “The younger generation simply consumes less alcohol,” Leroy said. This makes the financial impact of said seasonal effects even more devastating to the smaller domaines and vineyards while bigger producers cling on to what is left of their harvests. 

    This year’s harvest has been plentiful and record-breaking in some regions such as Champagne, mostly due to favourable conditions and the development of better technology. But this success has taken media attention away from the longer term crisis.

    In the summer of 2025 large floods hit the regions of Picardie in Belgium and Champagne in France, causing two deaths and large amounts of damage to private property and agricultural lands, further hindering the European wine market.

    Even worse, in the case of an increase of two degrees Celsius (35 degrees Fahrenheit) of global temperatures, scientists warn that the world may pass a tipping point (a point of irreversibility) in the patterns of ocean currents, potentially causing drastic change to the European climate as we know it — a threat that has been mostly ignored by mass media and climatological institutions. 

    And that threat is only about 20 years from now.

    Some grapes suffer, others thrive.

    This doesn’t mean, however, that absolutely all regions will suffer and that there are no solutions. In some southern parts of Sweden for instance, a multitude of new, more resilient vines have laid the foundation for a Scandinavian wine industry, made possible due to the changes experienced in the local climate. 

    “While there have been some exceptions, notably in 2024, wine production has been top quality,” Leroy said. “The earlier harvests have their advantages.”

    As older, more renowned wine producing regions lose their significance, this instability may prove a good time for newer regions and producers with other defined traits such as Scandinavia, the Balkans and the Agaises vineyard with their chalky ground and distinct latitude to fill in the gap left by the older producers. 

    Of course, a solution to the entire issue would be the halting or at least the delaying of climate change through the lowering of consumption and of carbon emissions. But such halting would take a tremendous individual and national effort that is lacking in Europe and in the world. 

    Thus, this problem presents us with yet another reason to continue the costly yet imperative fight against the climate crisis and all effects that it causes.


    Questions to consider:

    1. What does the author mean by a “tidal wave” of change that has hit Europe?

    2. How can climate change help grape growing in some regions when it devastates other regions?

    3. Can you think of other long-time industries that have been affected by climate change?

  • Empowering youth through environmental storytelling

    Empowering youth through environmental storytelling

    Through storytelling, we can bring climate-related data to life. Through storytelling, young people can use their voice and the voices of those around them to turn something complex, global and overwhelming, into something local, tangible and meaningful. Through storytelling, young people can help shift narratives and bring to the forefront stories of action and of hope.

    This is the idea behind the EYES climate storytelling curriculum.

    Now available on the eyesonclimate.org website, the curriculum is the culmination of the Empowering Youth through Environmental Storytelling project (EYES), an Erasmus+ co-funded project by News Decoder, The Environment and Human Rights Academy (TEHRA) and Young Educators European Association.

    The Climate Change 101 unit begins with the basics: human activities driving climate change and what temperature increase means for our planet. Students are tasked with producing an article that explains the topic to a younger audience.

    A unit on Climate Injustice walks students through the uncomfortable reality that those causing climate change are suffering the least from its impacts. Those who have contributed the least? They tend to be in the grip of climate change.

    Human stories from a man-made disaster

    We know that learning about the devastations of the climate crisis can leave young people feeling anxious and angry. We also know from the teachers who piloted the EYES curriculum that it’s important to localise these topics.

    So in the Climate Injustice unit, students are tasked with finding a human story: someone to illustrate climate injustice at play in their local area or region.

    Hearing stories about people lets us understand the reality of an issue. Telling these stories gives young people a device for meaning-making and a platform for agency.

    In our Systemic Change unit, students learn about the interconnected mechanisms that keep our economy rooted in endless economic growth and fossil fuel use. They learn about the ‘deep’ leverage points for making change — the rules, the goals and the mindset of a system. They research case studies on commodity supply chains and form their questions into a story pitch.

    Our curriculum runs across school subjects for students between 15 and 18 years of age. Other units include: Tipping Points, Planetary Boundaries, Human–Nature Connection, The Carbon Budget, Doughnut Economics and a Climate Justice Case Study.

    Solutions are out there.

    In Systemic Solutions to the Climate Crisis, we showcase seven inspiring examples of climate solutions from around the world, from local projects such as community-owned solar panels in Mexico to the transition to renewables in Uruguay, to global movements such as recognising the rights of nature or degrowth in the Global North.

    Meaningful action can happen at any scale. By engaging with these case studies, students can see that stories of just and transformative systems change happen all around them.

    There are so many stories yet to be told, and that in itself is empowering.

    To bolster student projects, the curriculum includes units on journalism and storytelling: The Principles of Journalism, Fact Checking and Misinformation, Interviewing and How to Write a Pitch, Write an Article and Produce a Podcast.

    “Storytelling can turn young people into active users of climate knowledge, and even change makers,” said Andreea Pletea, The Environment and Human Rights Academy programme manager. “Students can even help shift dominant narratives by bringing to the surface systemic solutions to the environmental crises that also address inequalities.”

    Causes and systems

    Aside from storytelling, the main focus of the EYES curriculum is on systems thinking and climate injustice.

    “We invite learners to go upstream to the root causes of the crises we face, and question why, despite increasing awareness, meaningful action often lags behind,” Pletea said. “Seeing the big picture particularly through systems thinking and global justice can also help young people make sense of what’s going on in their own local context.”

    Pletea said that ultimately, the goal is to plant a seed. “That all of us, including young people, are more than consumers,” she said. “We are citizens with a voice and power to act and demand change, and especially when we come together.”

    The EYES project itself began as a seed. TEHRA and News Decoder came together to improve climate change education through storytelling, and created a set of materials that were piloted in multiple education contexts across Europe, Africa and Latin America.

    The seeds to stories

    In Slovenia, Kenya and Colombia, pilot students exchanged letters on their local experiences of climate change. In Kosovo, a Roma community of young people visualised their personal experience of climate change through art.

    At a summer camp in Belgium, students played climate change games, pulled apart the individual carbon footprint and were guided through a nature meditation. In Kenya, students visited the precious Karura national park and wrote stories about tipping points and the value of forests.

    The feedback from students and educators, including at a three-day educators workshop in Brussels in October, helped shape and restructure the curriculum. It evolved into a set of off-the-shelf resources that can be used by multiple teachers in one school or independently by learners.

    If you are an educator, we invite you to dive into climate change with your students and use the EYES curriculum. Students need to learn about the root causes of the climate crisis so that they know in which direction to head — in their future careers as much as in their personal set of values.

    Through storytelling, young people can engage with the reality that is climate change, both as authors and as listeners. Storytelling is the way we understand ourselves: why we act the way we do and how together we can solve the problems that humankind has caused.


    Questions to consider:

    1. How can storytelling can turn someone into an active user of climate knowledge?

    2. What types of climate activities did students in different countries do through the EYES lessons?

    3. What stories about climate change have you found interesting to read or hear about?

  • Are you storing toxic waste in your home or car?

    Are you storing toxic waste in your home or car?

    Los Angeles, California has one of the largest economies in the world. It also has the largest concentration of electric vehicles in the United States. Los Angeles is my hometown and the same place where recent wildfires burned whole neighborhoods to the ground.

    With the fires came the destruction of thousands of lithium-ion batteries in cars, electronics and kitchen appliances.

    The fires started on 7 January 2025, and ended 24 days later. In October of 2025, police arrested a man from the state of Florida for starting the fire, but it was the near perfect environmental conditions that caused the fires to grow fast and move quickly. These fires are thought to have caused an estimated economic loss of between $28 billion and $53.8 billion, and have destroyed upwards of 16,000 structures.

    The fires wreaked havoc on my local community for an entire month. Just miles from my house, I witnessed the destruction these fires caused. Entire residential street blocks lined not with houses, but with rubble. I saw people milling about in front of houses, and I watched one woman stare with a stone-cold look on her face at the remains of a house burned to ashes.

    My family and many others were lucky we were far enough from the fires that we didn’t suffer any loss. Still, even those who didn’t lose their homes suffered from poor air quality.

    “Our business was down 75% immediately after the fires,” said Leila Jersualem, a local business owner. “Because soccer is an outdoor activity, air quality was a frequent concern voiced by our families.”

    Chemicals complicate cleanup.

    The fires also caused the release of many chemicals into the air. One of the most dangerous chemical transmitters, it turns out, are lithium-ion batteries that release toxic gases when burned and can explode when lit on fire.

    Due to this, the U.S. Environmental Protection Agency (EPA) had to safely remove more than a thousand burnt lithium-ion batteries from homes and vehicles, among other places.

    A schoolmate I interviewed at the time lived in the Pacific Palisades area. He told me he couldn’t enter his house due to toxic chemical residue from these destroyed batteries and other substances. He also didn’t think he’d ever move back in because of the dangers from these chemicals, which find their way onto household items and surfaces. Months later, he has still not moved back in.

    Cleanup from the Los Angeles fires has become an arduous task. Chris Myers, a lithium-ion battery tech specialist for the EPA, told reporter Erin Stone in nonprofit news site LAist that to clean up the batteries special teams collect them in sealed containers and take them to places where they can be discharged into a saltwater brine solution that extracts any remaining energy.

    The batteries are then crushed, and sent to a recycler who salvages critical minerals.

    The dangers from batteries are global.

    Myers told Stone that the heat from fires can cause a “thermal runaway” — the heat gets so intense that it causes a chemical reaction that creates more heat. When this happens, the batteries can emit toxic chemicals harmful to people in the area, and the chemicals, such as hydrogen chloride and hydrogen cyanide, can cause problems in the respiratory system.

    If a lithium-ion battery catches on fire, anyone within 25 meters has to evacuate and move out of the danger zone.

    Around the world, there were many incidents regarding the safety of lithium-ion batteries. In New York City, lithium-ion batteries were the leading cause of fire-related deaths in 2024. Additionally, lithium-ion batteries make up half of all garbage truck-related fires around the United States.

    One of the largest lithium battery storage and power plants caught on fire in Northern California in January 2025. The nonprofit news site Politico found that, in France, the number of fires at waste facilities caused by lithium batteries in common household items doubled between 2019 and 2023. In South Korea, more than 22 people were killed from a lithium battery explosion in a factory south of Seoul in June 2024.

    There are other problems with lithium ion batters. Conditions at lithium mines have raised some ethical questions, for example. In the U.S. state of Nevada, new lithium mines permitted by the Trump administration are preventing indigenous people from accessing sacred cultural areas, and raising fears of harm to drinking water and overall health of the local people.

    Do the benefits outweigh the danger?

    With all this danger, why are the batteries so prevalent in our homes? It is difficult to deny how useful they’ve been in humanity’s quest for clean energy.

    When comparing lithium-ion batteries to the internal combustion engine, we can see that over a car’s entire lifetime, ones with lithium-ion batteries will contribute less of a carbon footprint.

    It’s not far off to say that lithium-ion batteries have renovated our modern world.

    But even though there are many positives to using lithium-ion batteries, such as renewable energy, they’re only a small part of the actual solution and there are some alternatives.

    Vanadium flow batteries and sodium-ion batteries, for example, are considered viable alternatives to lithium-ion batteries. Sodium-ion batteries are faster to charge, and have a longer lifespan than lithium-ion batteries.

    Weighing alternatives

    The vanadium flow battery doesn’t decay and can contain the same level of recharge throughout the entire batteries’ lifetime. Also, unlike lithium batteries, vanadium flow batteries are non-flammable, making them much safer, especially in the event of fire.

    However, like lithium-ion batteries, they take significant resources to make, and their environmental and social impacts are high.

    When buying a car, getting a battery-powered car may be better for the environment, but consumers should be aware of the dangerous impacts of lithium-ion batteries.

    The effects of these batteries are felt everywhere, some good and some bad. The implications of them in the Los Angeles fires, however, raise questions on how safe they are to people and the environment.

    Further advancement of other parts of the climate solution must take place soon if we want to make a big impact in safer renewable energy.


    Questions to consider:

    1. What makes lithium-ion batteries dangerous?

    2. What alternatives to lithium-ion batteries are there for electric cars?

    3. What products do you use in your home that might contain a lithium-ion battery?

  • Why so much confusion over climate change?

    Why so much confusion over climate change?

    Bwambale estimates that less than 1% of the global population truly grasps the implications of climate change. “Even worse are Ugandans,” he said.

    Gerison pointed out that much of the population of Uganda is young. “With 80% below the age of 25, many haven’t witnessed the full extent of climate changes,” he said.

    A diminishing crop is easily understood.

    Janet Ndagire, Bwambale’s colleague, said it is difficult for Ugandan natives to connect with climate campaigns. They often perceive them as obstacles to survival rather than crucial interventions.

    “Imagine telling someone who relies on charcoal burning for survival that cutting down a tree could be hazardous!” Ndagire said. “It doesn’t make sense to them, especially when the tree is on their plot of land.”

    Reflecting on personal experiences, Ndagire recalled childhood days of going to sleep fully covered. Nowadays it is too hot to do that, he said.

    Ssiragaba Edison Tubonyintwari, a seasoned bus driver originally from western Uganda but currently driving with the United Nations, recounts the challenges of driving between 5 and 9 AM in the Albertine rift eco-region especially around the Ecuya forest reserve.

    “It would be covered in mist,” said Tubonyintwari. “We’d ask two people to stand in front, one on either side of the bus, signalling for you to drive forward, or else, you couldn’t see two metres away. Currently, people drive all day and night!”

    Irish potatoes in the African wetlands

    What happened? Tubonyintwari pointed to unauthorised tree cutting in the reserve, residential constructions and the cultivation of tea alongside Irish potatoes in the wetlands. The result was rising temperatures.

    His account supplements a Global Forest Watch report which puts commodity-driven deforestation above urbanisation.

    It’s notable that Tubonyintwari didn’t explicitly use the term “climate change,” yet the sexagenarian can effectively explain the underlying concept through his detailed description of altered environmental conditions.

    Global Forest Watch reports alarming deforestation trends, with 5.8 million hectares lost globally in 2022. In Uganda, more than 6,000 deforestation alerts were recorded between 22 and 29 November this year.

    The consequences of such environmental degradation are dire. Ndagire emphasised that those who once wielded axes and chainsaws for firewood are now the very individuals facing reduced crop yields due to extreme weather conditions.

    Even as Uganda grapples with the aftermath of a sudden surge in heavy rains from last October, Bwambale questions the country’s meteorological department, highlighting the failure to provide precise explanations and climate-aware preparations.

    These interconnected narratives emphasise the need for accessible climate campaigns and community-driven solutions. As COP28 gathers elites, the call for a simplified narrative gains prominence, mirroring successful communication models seen during the Covid-19 pandemic; else it’s the same old throwing of good money after bad.


    Questions to consider:

    1. Why does deforestation continue in places like Uganda when people know about its long-term consequences?

    2. In what ways are high level discussions about climate change disconnected from people’s everyday experiences?

    3. In what way do you think scientists and environmentalists need to change the climate change narrative?

  • Colleges build environmental lessons into degrees

    Colleges build environmental lessons into degrees

    by Olivia Sanchez, The Hechinger Report
    November 5, 2025

    LA JOLLA, Calif. — On a Thursday this fall, hundreds of students at the University of California, San Diego, were heading to classes that, at least on paper, seemed to have very little to do with their majors. 

    Hannah Jenny, an economics and math major, was on their way to a class on sustainable development. Angelica Pulido, a history major who aspires to work in the museum world, was getting ready for a course on gender and climate justice. Later that evening, others would show up for a lecture on economics of the environment, where they would learn how to calculate the answer to questions such as: “How many cents extra per gallon of gas are people willing to pay to protect seals from oil spills?”

    Although most of these students don’t aspire to careers in climate science or advocacy, the university is betting that it’s just as important for them to understand the science and societal implications of climate change as it is for them to understand literature and history, even if they’re not planning to become writers or historians. UCSD is perhaps the first major public university in the country to require all undergraduate students to take a class on climate change to earn their degree. 

    The requirement, which rolled out with first-year students last fall, came about because UCSD leaders believe students won’t be prepared for the workforce if they don’t understand climate change. Around the globe, global warming is already causing severe droughts, water scarcity, fires, rising sea levels, flooding, storms and declining biodiversity; leaders at UCSD argue every job will be affected. 

    And even as President Donald Trump dismisses climate change as a hoax and cancels funding for research on it, other colleges are also exploring how to ensure students are knowledgeable about the subject. Arizona State University began requiring that students take a class in sustainability last year, while San Francisco State University added a climate justice class requirement to begin this fall. 

    “You can’t avoid climate change,” said Amy Lerner, a professor in the urban planning department at UCSD. “You can’t escape it in the private sector. You can’t escape it in the public sector. It’s just everywhere.” Students, she said, must be made ready to engage with all of its likely consequences.

    UCSD, a public university that serves roughly 35,000 undergraduate students, is not demanding that everyone sign up for Climate Change 101. Instead, students can fulfill the requirement by taking any of more than 50 classes in at least 23 disciplines across the university, including sustainable development, the course Jenny is taking. 

    There’s also psychology of the climate crisis, religion and ecology, energy economics, and several classes in the environmental science and oceanography departments, among others. And leaders at the university are working to develop more classes that satisfy the requirement, including one on the life cycle of a computer.

    Bryan Alexander, an adjunct professor at Georgetown University and author of a book on higher education and the climate crisis, said that while colleges have long taught about climate change in classes related to ecology, climatology and environmental science, it’s only been in the last decade or so that he’s seen other disciplines tackle the topic. 

    Climate change, Alexander said, “is the new liberal arts” — and colleges should take it seriously. 

    K. Wayne Yang, a UCSD provost who served on the original group that advocated for the requirement, said every industry and career field will experience the effects of climate change in some way. Health care providers need to know how to treat people who have been exposed to extreme heat or wildfire smoke; psychologists need to understand climate anxiety; and café owners need to know how the price of coffee changes in response to droughts or other natural disasters in coffee-growing regions.  

    Jenny, the senior taking a class on sustainable development, is eager to get answers to a question that has, in their three years as an economics and mathematics major, become difficult not to ponder: How can economic growth be the silver bullet of societal change if it has so many negative consequences for the planet?

    “It’s definitely my hope that this is a class that will teach me something new about how to consider humanity’s path forward without destroying this earth, without destroying each other, without sacrificing quality of life for any person on this planet,” Jenny said. 

    Jenny isn’t subject to the requirement because they entered college before it rolled out. But they said they like the idea of encouraging students to step outside their comfort zones and fields of study and, in many cases, consider their future career paths in the context of the changing climate.

    Other students, like junior Pulido, don’t see a specific link between climate change and their future careers. Pulido, who has spent the last few years working in the visitors center at San Diego’s Balboa Park and aspires to work in museums, said she signed up for the gender and climate justice class simply because it sounded interesting to her. She believes climate change is important, and she’s hoping that taking this class will help give her a better idea of how its role in history and might play into her career.

    Related: How colleges can become ‘living labs’ for combating climate change  

    Colleges are taking different approaches to teaching their students about climate change, with some requiring a course in sustainability, a broad discipline that goes beyond the specific scientific phenomenon of climate change.

    At Arizona State, sustainability classes can cover anything about how human, social, economic, political and cultural choices affect human and environmental well-being generally, said Anne Jones, the university’s vice provost for undergraduate education.

    Dickinson and Goucher colleges have had such requirements since 2015 and 2007, respectively. 

    At San Francisco State University, leaders said they instead chose to require climate justice for all students, beginning with the class of 2029, because of the urgency of understanding how climate change affects communities differently. 

    Students need to understand broader systems of oppression and privilege so that they can address the unequal effects of climate change for “communities of color, low-income communities, global south communities and other marginalized communities,” said Autumn Thoyre, co-director of Climate HQ, the university’s center for climate education, research and action.

    Yang and other UCSD leaders believe that, despite the increased politicization of climate change under Trump, they’ve received little pushback on the new requirement because of the university’s reputation as a climate-concerned institution. (It descended from the Scripps Institution of Oceanography, initially founded in 1903.) But this model may not work as well on other campuses. 

    In communities where people’s livelihoods depend on activities that contribute to climate change, like coal mining or oil production, educators may have to modify their approach so as to not come off as offensive or threatening, said Jo Tavares, director of the California Center for Climate Change Education at West Los Angeles College. 

    “Messaging is so important, and education cannot be done in a way that just forces facts upon people,” Tavares said.

    At UCSD, to meet the graduation requirement, a course must be at least 30 percent about climate change: For example, a class that meets twice a week for a 10-week term must have at least six of its 20 sessions be about climate change. And the course syllabus must address at least two of the following four categories: the scientific aspects; human and social dimensions; project-based learning; or solutions.

    The first time Lerner, the urban studies professor, applied for her sustainable development course to count toward the requirement, in July 2024, the committee told her she needed to better explain how the class addressed climate change. It wasn’t enough to simply have “sustainable” in the course name, committee members told her; she had to better articulate the role of climate change in sustainable development, a course she’s been teaching some version of for nearly 20 years. 

    Her students helped her go through the syllabus and identify all the points where she was teaching about how development contributes to climate change, even if she wasn’t explicitly putting those words to paper. After Lerner revised the descriptions of the class topics and made a few additions, the class was approved, she said. 

    On that fall Thursday, Lerner walked around her large glass-walled classroom while discussing development and globalization with the 65 undergraduate students in her sustainable development class. They covered how to balance equity, economy and environment in development, as well as various ways to measure the well-being of societies, including gross national income, food security, birthrate and infant mortality, happiness, fertility, education and lifespan. Lerner peppered her lecture with jokes and relatable examples, asking, for example, how many siblings students had before explaining the role of fertility and birth rate in a healthy society. (One student had 12, but the average was closer to two.)

    Lerner, who now chairs the committee that decides which classes meet the requirement, said most of her students come in with the understanding that climate change is caused by rising levels of carbon dioxide entering the atmosphere, and some have even used an online tool to calculate their own carbon footprints. Often, their education has been focused on the hard science aspect of climate change, but they haven’t learned about what society has experienced as a result of climate change, she said. 

    When she asks them what can be done about climate change, she said, “they’re deer in the headlights.”

    Across campus, economics professor Mark Jacobsen teaches a lecture class every Thursday night on the economics of the environment. It meets the climate change requirement, but it also covers a core economics idea, he said: achieving efficiency. 

    Jacobsen is teaching students the formulas and methods they’ll need to answer questions like whether it’s worth it to spend $1 billion now to build renewable energy sources to avoid $10 billion in natural disaster cleanup in 30 years.

    Though Jenny hasn’t taken Jacobsen’s class, this is exactly the type of dilemma they’re worried about. 

    Jenny, a public transit enthusiast so dedicated that they got a commercial driver’s license just to drive for Triton Transit, the campus bus system, said the requirement encourages students to face the climate crisis rather than shy away from it. 

    “It can be easy to kind of put your head down and be like, ‘That is too big for me to think about, and too scary,’” Jenny said. But it’s imperative, they added, that students be “forced to reckon with it and think about it and talk about it, to have that knowledge kind of swirling around in your head.”

  • When a company’s enviro claims sound convincing …

    When a company’s enviro claims sound convincing …

    Many companies contribute to the climate crisis and make a profit doing so. As consumers and governments pressure them to reduce their carbon emissions, they look for ways to make themselves appear environmentally friendly. This is called green marketing.

    As a journalist, you need to learn to spot what a business really means by its green marketing.

    Greenwashing is when a brand makes itself seem more sustainable than it really is, as a way to get consumers to buy their product. For example, let’s look at fashion, an industry that is responsible for between 2 and 8% of global greenhouse gas emissions.

    In the absence of environmental legislation around the fashion industry a business might get themselves certified under a sustainability certification scheme — these are standards developed by governments or industry groups or NGOs to measure such things as energy efficiency or processes that are low carbon or carbon neutral. There are more than 100 different such certification programs.

    Companies tout these certifications. But a 2022 study by the Changing Markets Foundation (CMF) found that the standards set by the majority of the 10 or more popular certification initiatives for the fashion industry aren’t difficult to meet and lack accountability.

    Artificial claims about sustainability

    Fast fashion relies on cheap synthetic fibers, which are produced from fossil fuels such as oil and gas. And while you might assume that clothing with labels such as “eco” or “sustainable” might have fewer synthetics, you’d unfortunately be wrong.

    Another study by CMF found that H&M’s “conscious” clothing range, for example, contained 72% synthetics — which was higher than the percentage in their main collection (61%). And it’s not just H&M. While the same study found that 39% of products made some kind of green claim, almost 60% of these claims did not match the guidelines set out by the UK Competition and Markets Authority.

    The same is happening in the meat and dairy industry. Companies say they are reducing their environmental footprint by engaging in “regenerative agriculture”, a farming approach that aims to restore and improve ecosystem health. They argue that it reduces greenhouse gas emissions and helps store carbon in the soil.

    But relying on carbon storing in soil is not enough. An article in Nature Communications found that around 135 gigatonnes of stored carbon would be required to offset the emissions that come from the agriculture sector. This is roughly equivalent to the amount of carbon lost due to agriculture over the past 12,000 years, according to CMF.

    But companies grab onto these empty promises, perhaps knowing that the general public might only see regenerative agriculture and other “green narratives” as promising.

    Look for real solutions to climate change.

    For example, Nestlé tells their customers that it is addressing the carbon footprint of the agriculture industry by supporting regenerative agriculture, stating on its website that in 2024, some 21% of the ingredients they source come from farmers adopting regenerative agriculture practices.

    When you understand that regenerative agriculture is not the solution it has been made out to be, only then can you see through Nestlé’s branding.

    So how can you spot greenwashing?

    Let’s say you saw a press release from a company in an industry that has historically relied heavily on fossil fuels. It tells its readers that it plans to be carbon neutral by a certain date, or that it’s using recycled materials for a large portion of its production, or that its future is “green”.

    You might first wonder, is this an example of how companies are moving away from fossil fuels and towards a green future? How can you tell?

    1. Be skeptical.

    When something has to tell you that it is green, it might not be. Start your investigation right there.

    For example, if you were looking at Nestlé’s regenerative agriculture campaign, you would need to find out what regenerative agriculture is and how much it is indeed reducing greenhouse gas emissions. You can do this by starting with a good Google search: e.g “regenerative agriculture and greenhouse gas emissions”.

    Once you click on a number of articles that report on this topic, you’ll be able to read about the different studies and data into the topic. Follow the sources used when an article cites a study or data. The article should hyperlink or list the sources. But those hyperlinks might take you to other secondary sources — other articles that cited the same data.

    For example, an article might cite this statistic: sustainability certifications increase consumer willingness to pay by approximately 7% on average. The article might cite as the source this study published in the journal Nature. But that article isn’t the original source of that data. It came from a 2014 study published in the Journal of Retailing.

    So try to find the primary source and see how credible or reputable it is. Who conducted the research in the first place?

    If you wanted to find out what H&M’s “conscious” range really meant, you would start by looking at H&M’s website and reports to look further into their claims. Then, follow those claims.

    2. Research the wider industry.

    Whether you’re reporting on fashion, agriculture or any other industry, look into where its emissions are coming from, which companies are claiming what and what the evidence says needs to be done in order for these industries to reduce their emissions.

    Providing context is important. What percentage of global greenhouse gas emissions is this industry responsible for? Is it getting better or worse? What legislation is in place to reduce emissions from these industries? In order for you and your audience to understand the greenwashing of any company, this background information is vital.

    3. Go straight to the company.

    Once you’ve conducted some initial research, follow up with the company if you are using it as an example or focus for your article. On Nestlé’s website, for example, you can find contact details for their communications, media or PR department. Send them an email saying something like the following:

    “I am writing an article on regenerative agriculture and I’ve found some studies that show that soil sequestration through these practices are in fact not enough to be a real climate solution. Can you please provide me with a comment on what Nestlé thinks about this?”

    They might not answer, but that also says a lot. If they don’t reply to you after one or two follow-up emails, you might try calling them.

    If you try several times and in different ways to contact them and they failed to respond, you can state that in your article. That way your readers know you made the effort.

    Claims from corporations that they are doing all they can to help the planet are easy to make. But if we really want to slow down climate change, significant efforts have to be made. And it is the role of journalists to hold companies to account for the claims they make.


    Questions to consider:

    1. What is “greenwashing”

    2. What is one example of greenwashing?

    3. What criteria do you use when deciding whether to buy a company’s product?

  • Teachers unions leverage contracts to fight climate change

    Teachers unions leverage contracts to fight climate change

    This story first appeared in Hechinger’s climate and education newsletter. Sign up here

    In Illinois, the Chicago Teachers Union won a contract with the city’s schools to add solar panels on some buildings and clean energy career pathways for students, among other actions. In Minnesota, the Minneapolis Federation of Educators demanded that the district create a task force on environmental issues and provide free metro passes for students. And in California, the Los Angeles teachers union’s demands include electrifying the district’s bus fleet and providing electric vehicle charging stations at all schools. 

    Those are among the examples in a new report on how unionized teachers are pushing their school districts to take action on the climate crisis, which is damaging school buildings and disrupting learning. The report — produced by the nonprofit Building Power Resource Center, which supports local governments and leaders, and the Labor Network for Sustainability, a nonprofit that seeks to unite labor and climate groups — describes how educators can raise demands for climate action when they negotiate labor contracts with their districts. By emphasizing the financial case for switching to renewable energy, educators can simultaneously act on climate change, improve conditions in schools and save districts money, it says. 

    As federal support and financial incentives for climate action wither, this sort of local action is becoming more difficult — but also more urgent, advocates say. Chicago Public Schools has relied on funding for electric buses that has been sunsetted by the Trump administration, said Jackson Potter, vice president of the Chicago Teachers Union. But the district is also seeking other local and state funding and nonprofit support.

    Bradley Marianno, an associate professor in the College of Education at the University of Nevada, Las Vegas, said that educator unions embracing climate action is part of a move started about 15 years ago in which more progressive unions — like those in Chicago, Los Angeles and elsewhere — focus on “collective good bargaining,” or advocating for changes that are good for their members but also the broader community. But this approach is unlikely to catch on everywhere: “The risk lies in members feeling that core issues like wages and working conditions are being overlooked in favor of more global causes,” he wrote in an email. 

    I recently caught up with Potter, the CTU vice president, about the report and his union’s approach to bargaining for climate action. Collaborating with local environmental and community groups, the Chicago Teachers Union ultimately succeeded in winning a contract that calls for identifying schools for solar panels and electrification, expanding indoor air quality monitoring, helping educators integrate climate change into their curriculum, and establishing training for students in clean energy jobs, among other steps. 

    This interview has been edited for length and clarity. 

    The report talks about contract negotiations being an underused — and effective — lever for demanding climate action. Why do you see that process as such an opportunity for climate action?

    On the local level, our schools are 84, 83 years old on average. There is lead paint, lead pipes, mold, asbestos, PCBs, all kinds of contamination in the HVAC system and the walls that require upgrades. By our estimate, the district needs $30 billion worth of upgrades, and right now I think they spend $500 million a year to just do patch-up work. We’re at a point where it’s a system fail of epic proportions if we can’t figure out a way to transition and make things healthier. And so if you’re going to do a roof repair, put solar on it, have independence from fossil fuels, clean air in areas that have faced environmental racism and contamination. 

    We’re also dealing with a legacy of discrimination and harm, and that is true of the nation. So how do we get out of this and also save the planet and also prevent greater climate events that further destabilize vulnerable communities and put people at risk? It made sense for us to use our contract as a path to do both things — deal with this local crisis that was screaming for new solutions and ideas, in a moment when the climate is on fire, literally.  

    How challenging was it to get educators to view climate issues as a priority? There are so many other things, around pay and other issues, on the table. 

    When we started, it almost felt like people in the membership, in the community, viewed it as a niche issue. Like, ‘Oh, isn’t that cute, you care about green technology.’ As we figured out how to think about it and talk about it and probe where people were having issues in their schools, it became really obvious that when you started talking about asbestos, lead and mold remediation — and helping communities that have been hit the hardest with cumulative impacts and carcinogens and how those things are present in schools — that became much more tangible. Or even quality food and lunch and breakfast for students who are low-income. It went from bottom of the list to top of the list, instantaneously. 

    Your contract calls for a number of climate-related actions, including green pathways for students and agreements with building trade unions to create good jobs for students. Tell me about that. 

    We’re trying to use the transformation of our facilities as another opportunity for families and students in these communities that have been harmed the most to get the greatest benefit from the transformation. So if we can install solar, we want our students to be part of that project on the ground in their schools, gaining the skills and apprenticeship credentials to become the electricians of the future. And using that as a project labor agreement [which establishes the terms of work on a certain project] with the trades to open doors and opportunities. The same goes for all the other improvements — whether it’s heat pumps, HVAC systems, geothermal. And for EV — we have outdated auto shop programming that’s exclusively based on the combustible engine reliant on fossil fuels, whereas in [the nearby city of] Belvidere they are building electric cars per the United Auto Workers’ new contract. Could we gain a career path on electric vehicles that allows students to gain that mechanical knowledge and insight and prepares them for the vehicles of the future? 

    The report talks about the Batesville School District in Arkansas that was able to increase teacher salaries because of savings from solar. Have you tried to make the case for higher teacher salaries because of these climate steps?  

    The $500 million our district allocates for facility upgrades annually comes out of the general fund, so we haven’t at all thought about it in terms of salary. We’ve thought about it in terms of having a school nurse, social worker, mental health interventions at a moment when there is so much trauma. We see this as a win-win: The fewer dollars the district has to spend on facility needs means the more dollars they can spend on instructional and social-emotional needs for students. In terms of the Arkansas model, it’s pretty basic. If you get off the fossil fuel pipelines and electric lines and you become self-sufficient, essentially, powering your own electric and heat, there is going to be a boon, particularly if there are up-front subsidies. 

    Math and climate change 

    When temperatures rise in classrooms, students have more trouble concentrating and their learning suffers — in math, in particular. That’s according to a new report from NWEA, an education research and testing company.

    The report, part of a growing body of evidence of the harms of extreme heat on student performance, found that math scores declined when outdoor temperatures on test days rose above 80 degrees Fahrenheit. Students in high-poverty schools, which are less likely to have air conditioning, saw declines up to twice as large as those in wealthier schools. 

    The learning losses grew as temperatures rose. Students who took tests on 101-degree days scored roughly 0.06 standard deviations below students who tested when temperatures were 60 degrees, the equivalent of about 10 percent of the learning a fifth grader typically gains in a school year. 

    It’s not entirely clear why student math scores suffer more than reading when temperatures rise. But Sofia Postell, an NWEA research analyst, said that on math tests, students must problem-solve and rely on their memories, and that kind of thinking is particularly difficult when students are hot and tired. Anxiety could be a factor too, she wrote in an email: “Research has also shown that heat increases anxiety, and some students may experience more testing anxiety around math exams.”

    The study was based on data from roughly 3 million scores on NWEA’s signature MAP Growth test for third to eighth graders in six states. 

    The report urged school, district and state officials to take several steps to reduce the effects of high heat on student learning and testing. Ideally, tests would be scheduled during times of the year when it wasn’t so hot, it said, and also during mornings, when temperatures are cooler. Leaders also need to invest in updating HVAC systems to keep kids cool. 

    “Extreme heat has already detrimentally impacted student learning and these effects will only intensify without action,” wrote Postell. 

    Mea culpa: A quick note to say I got two things wrong in my last newsletter — the name of the Natural Resources Defense Council was incorrect, as was the number of hours of learning California students have missed so far this year. It’s more than 54,000.
