Hannah Wiseman, Penn State The U.S. Supreme Court in March 2025 ended a decade-old lawsuit filed by a group of children who sought to hold the federal government responsible for some of the consequences of climate change. But just two months earlier, the justices allowed a similar suit from the city and county of Honolulu, Hawaii, to continue against oil and gas companies. Evidence shows that fossil fuel companies, electric utilities and the federal government have known about climate change, its dangers and its human causes for at least 50 years. But the steps taken by fossil fuel companies, utilities and governments, including the U.S. government, have not been enough to meet international climate targets. So local and state governments and citizens have asked the courts to force companies and public agencies to act. Their results have varied, with limited victories to date. But the cases keep coming.

Attacking the emissions themselves

In general, legal claims in the U.S. can be based on the U.S. and state constitutions, federal and state laws, or what is called “common law” – legal principles created by courts over time. Lawsuits have used state and federal laws to try to limit greenhouse gas pollution itself and to seek financial compensation for alleged industry cover-ups of the dangers of fossil fuels, among many other types of claims. In 2007 the U.S. Supreme Court determined that greenhouse gases such as carbon dioxide emitted from motor vehicles were a “pollutant” under the federal Clean Air Act. As a result, the court ordered the Environmental Protection Agency to either determine whether greenhouse gases from new vehicles contribute to climate change, and therefore endanger human health, or justify its refusal to study the issue. In 2009 the EPA found that carbon dioxide emissions did in fact endanger human health – a decision called the “endangerment finding.” In 2010 it imposed limits on carbon dioxide emissions from new vehicles and, later, from newly constructed power plants. But related EPA efforts to regulate emissions from older power plants – the ones that emit the most pollution – failed when challenged in court on the grounds that they went too far in limiting emissions beyond the power plants’ own properties. The Biden administration had finalized a new rule to clean up these older plants, but the Trump administration is now seeking to withdraw it. The Trump administration is also now beginning the complicated process of reviewing the 2009 endangerment finding. It could try to remove the legal basis for EPA greenhouse gas regulations.

A common-law approach

In response to this federal executive seesaw of climate action, some legal claims use a court-based, or common law, approach to address climate concerns. For instance, in Connecticut v. American Electric Power, filed in 2004, nine states asked a federal judge to order power plants to reduce their emissions. The states said those emissions contributed to global warming, which they argued met the federal common law definition of a “public nuisance.” That case ended when the U.S. Supreme Court ruled in 2011 that the existence of a statute – the federal Clean Air Act – meant common law did not apply. Other plaintiffs have tried to use the “public nuisance” claim or a related common-law claim of “trespass” to force large power plants or oil and gas producers to pay climate-related damages. But in those cases, too, courts found that the Clean Air Act overrode the common-law grounds for those claims. With those case outcomes, many plaintiffs have shifted their strategies, focusing more on state courts and seeking to hold the fossil fuel industry responsible for allegedly deceiving the public about the causes and effects of climate change.

Examining deception

In many cases, state and local governments are arguing that the fossil fuel industry knew about the dangers of climate change and deceived the public about them, and that the industry exaggerated the extent of its investments in energy that doesn’t emit carbon. Rather than directly asking courts to order reduced carbon emissions, these cases tend to seek damages that will help governments cover the costs associated with climate change, such as construction of cooling centers and repair of roads damaged by increased precipitation. In legal terms, the lawsuits are saying oil and gas companies violated consumer-protection laws and committed common-law civil violations such as negligence. For instance, the city of Chicago alleges that major petroleum giants – along with the industry trade association the American Petroleum Institute – had “abundant knowledge” of the public harms of fossil fuels yet “actively campaigned” to hide that information and deceive consumers. Many other complaints by states and local governments make similar allegations. Another lawsuit, from the state of Maine, lists and provides photographs of a litany of internal industry documents showing industry knowledge of the threat of climate change. That lawsuit also cites a 1977 memo from an Exxon employee to Exxon executives, which stated that “current scientific opinion overwhelmingly favors attributing atmospheric carbon dioxide increase to fossil fuel consumption,” and a 1979 internal Exxon memo about the buildup of carbon dioxide emissions, which warned that “(t)he potential problem is great and urgent.” These complaints also show organizations supported by fossil fuel companies published ads as far back as the 1990s, with titles such as “Apocalypse No” and “Who told you the earth was warming … Chicken Little?” Some of these ads – part of a broader campaign – were funded by a group called the Information Council for the Environment, supported by coal producers and electric utilities. Courts have dismissed some of these complaints, finding that federal laws overrule the principles those suits are based on. But many are still winding their way through the courts. In 2023 the Supreme Court of Hawaii found that federal laws do not prevent climate claims based on state common law. In January 2025 the U.S. Supreme Court allowed the case to continue.

Other approaches

Still other litigation approaches argue that governments inadequately reviewed the effects of greenhouse gas emissions, or even supported or subsidized those emissions caused by private industry. Those lawsuits – some of which were filed by children, with help from their parents or legal guardians – claim the governments’ actions violated people’s constitutional rights. For instance, children in the Juliana v. United States case, first filed in 2015, said 50 years of petroleum-supporting actions by presidents and various federal agencies had violated their fundamental “right to a climate system capable of sustaining human life.” The 9th U.S. Circuit Court of Appeals ruled that their claim was a “political question” – meant for Congress, not the courts. The U.S. Supreme Court declined to reconsider that ruling in March 2025. But children in Montana found more success. The Montana Constitution requires state officials and all residents to “maintain and improve a clean and healthful environment … for present and future generations.” In 2024 the Montana Supreme Court determined that this provision “includes a stable climate system that sustains human lives and liberties.” The Montana Supreme Court also reviewed a state law banning officials from considering greenhouse gas emissions of projects approved by the state. The court found that the ban violated the state constitution, too. Since then, the Montana Supreme Court has specifically required state officials to review the climate effects of a project for which permits were challenged. Concerned people and groups continue to file climate-related lawsuits across the country and around the world. They are seeing mixed results, but as the cases continue and more are filed, they are drawing attention to potential corporate and government wrongdoing, as well as the human costs of climate change. And they are inspiring shareholders and citizens to demand more accurate information and action from fossil fuel companies and electric utilities.

What is “happiness” – and who gets to be happy?

Since 2012, the World Happiness Report has measured and compared data from 167 countries. The United States currently ranks 24th, between the U.K. and Belize – its lowest position since the report was first issued. But the 2025 edition – released on March 20, the United Nations’ annual “International Day of Happiness” – starts off not with numbers, but with Shakespeare.

“In this year’s issue, we focus on the impact of caring and sharing on people’s happiness,” the authors explain. “Like ‘mercy’ in Shakespeare’s ‘Merchant of Venice,’ caring is ‘twice-blessed’ – it blesses those who give and those who receive.”

Shakespeare’s plays offer many reflections on happiness itself. They are a record of how people in early modern England experienced and thought about joy and satisfaction, and they offer a complex look at just how happiness, like mercy, lives in relationships and the caring exchanges between people.

Contrary to how we might think about happiness in our everyday lives, it is more than the surge of positive feelings after a great meal, or a workout, or even a great date. The experience of emotions is grounded in both the body and the mind, influenced by human physiology and culture in ways that change depending on time and place. What makes a person happy, therefore, depends on who that person is, as well as where and when they belong – or don’t belong.

Happiness has a history. I study emotions and early modern literature, so I spend a lot of my time thinking about what Shakespeare has to say about what makes people happy, in his own time and in our own. And also, of course, what makes people unhappy.

From fortune to joy

“Happiness” derives from the Old Norse word “hap,” which meant “fortune” or “luck,” as historians Phil Withington and Darrin McMahon explain. This earlier sense is found throughout Shakespeare’s works. Today, it survives in the modern word “happenstance” and the expression that something is a “happy accident.”

But in modern English usage, “happy” as “fortunate” has been almost entirely replaced by a notion of happiness as “joy,” or the more long-term sense of life satisfaction called “well-being.” The term “well-being,” in fact, was introduced into English from the Italian “benessere” around the time of Shakespeare’s birth.

The word and the concept of happiness were transforming during Shakespeare’s lifetime, and his use of the word in his plays mingles both senses: “fortunate” and “joyful.” That transitional ambiguity emphasizes happiness’ origins in ideas about luck and fate, and it reminds readers and playgoers that happiness is a contingent, fragile thing – something not just individuals, but societies need to carefully cultivate and support.

For instance, early in “Othello,” the Venetian senator Brabantio describes his daughter Desdemona as “tender, fair, and happy / So opposite to marriage that she shunned / The wealthy, curled darlings of our nation.” Before she elopes with Othello she is “happy” in the sense of “fortunate,” due to her privileged position on the marriage market.

Later in the same play, though, Othello reunites with his new wife in Cyprus and describes his feelings of joy using this same term:

…If it were now to die,
‘Twere now to be most happy, for I fear
My soul hath her content so absolute
That not another comfort like to this
Succeeds in unknown fate.

Desdemona responds,

The heavens forbid
But that our loves and comforts should increase
Even as our days do grow!

They both understand “happy” to mean not just lucky, but “content” and “comfortable,” a more modern understanding. But they also recognize that their comforts depend on “the heavens,” and that happiness is enabled by being fortunate.

“Othello” is a tragedy, so in the end, the couple will not prove “happy” in either sense. The foreign general is tricked into believing his young wife has been unfaithful. He murders her, then takes his own life.

The seeds of jealousy are planted and expertly exploited by Othello’s subordinate, Iago, who catalyzes the racial prejudice and misogyny underlying Venetian values to enact his sinister and cruel revenge.

Happy insiders and outsiders

“Othello” sheds light on happiness’s history – but also on its politics.

While happiness is often upheld as a common good, it is also dependent on cultural forces that make it harder for some individuals to experience. Shared cultural fantasies about happiness tend to create what theorist Sara Ahmed calls “affect aliens”: individuals who, by nature of who they are and how they are treated, experience a disconnect between what their culture conditions them to think should make them happy and their disappointment or exclusion from those positive feelings. Othello, for example, rightly worries that he is somehow foreign to the domestic happiness Desdemona describes, excluded from the joy of Venetian marriage. It turns out he is right.

Because Othello is foreign and Black and Desdemona is Venetian and white, their marriage does not conform to their society’s expectations for happiness, and that makes them vulnerable to Iago’s deceit.

Similarly, “The Merchant of Venice” examines the potential for happiness to include or exclude, to build or break communities. Take the quote about mercy that opens the World Happiness Report.

The phrase appears in a famous courtroom scene, as Portia attempts to persuade a Jewish lender, Shylock, to take pity on Antonio, a Christian man who cannot pay his debts. In their contract, Shylock has stipulated that if Antonio defaults on the loan, the fee will be a “pound of flesh.”

“The quality of mercy is not strained,” Portia lectures him; it is “twice-blessed,” benefiting both giver and receiver.

It’s a powerful attempt to save Antonio’s life. But it is also hypocritical: Those cultural norms of caring and mercy seem to apply only to other Christians in the play, and not the Jewish people living alongside them in Venice. In that same scene, Shylock reminds his audience that Antonio and the other Venetians in the room have spit on him and called him a dog. He famously asks why Jewish Venetians are not treated as equal human beings: “If you prick us, do we not bleed?”

Shakespeare’s plays repeatedly make the point that the unjust distribution of rights and care among various social groups – Christians and Jews, men and women, citizens and foreigners – challenges the happy effects of benevolence.

Those social factors are sometimes overlooked in cultures like the U.S., where contemporary notions of happiness are marketed by wellness gurus, influencers and cosmetic companies. Shakespeare’s plays reveal both how happiness is built through communities of care and how it can be weaponized to destroy individuals and the fabric of the community.

There are obvious victims of prejudice and abuse in Shakespeare’s plays, but he does not just emphasize their individual tragedies. Instead, the plays record how certain values that promote inequality poison relationships that could otherwise support happy networks of family and friends.

Systems of support

Pretty much all objective research points to the fact that long-term happiness depends on community, connections and social support: having systems in place to weather what life throws at us.

And according to both the World Happiness Report and Shakespeare, contentment isn’t just about the actual support you receive but your expectations about people’s willingness to help you. Societies with high levels of trust, like Finland and the Netherlands, tend to be happier – and to have more evenly distributed levels of happiness in their populations.

Shakespeare’s plays offer blueprints for trust in happy communities. They also offer warnings about the costs of cultural fantasies about happiness that make it more possible for some, but not for all.

Daniel B. Oerther, Missouri University of Science and Technology and William Schonberg, Missouri University of Science and Technology Just 48 short years ago, movie director George Lucas used the phrase “A long time ago in a galaxy far, far away” as the opening to the first “Star Wars” movie, later labeled “Episode IV: A New Hope.” But at least four important aspects of the “Star Wars” saga are much closer – both in time and space – than Lucas was letting on. One, the ability to add blue food coloring to milk, was possible even at the time the first film came out. But in 2024, “Star Wars”-themed blue milk became periodically available in grocery stores. And we, an environmental health engineer and a civil engineer, know there are at least three more elements of these ancient, distant Lucas stories that might seem like science fiction but are, in fact, science reality.

Moisture farming

In that first movie, “Episode IV,” Luke Skywalker’s Uncle Owen was a farmer on the planet of Tatooine. He farmed water from air in the middle of a desert. It might sound impossible, but it’s exactly what experts discussed at the second International Atmospheric Water Harvesting Summit hosted by Arizona State University in March 2025. Each day, a human needs to consume about the equivalent of 0.8 gallons of water (3 liters). With more than 8 billion people living on the planet, that means engineers need to produce nearly 2.6 trillion gallons (10 trillion liters) of clean drinking water every year. Taken globally, rainfall would be enough, but it’s distributed very unevenly – including landing in the oceans, where it immediately becomes too salty to drink safely. Deserts, which cover about one-fifth of the Earth’s land area, are home to about 1 billion people. Researchers at places such as Berkeley have developed solar-powered systems that can produce clean drinking water from thin air. In general, they use a material that traps water molecules from the air within its structure and then use sunlight to condense that water out of the material and into drinkable liquid. But there is still a ways to go before they are ready for commercial distribution and available to help large numbers of people.

Space debris

When the second Death Star was destroyed in “Return of the Jedi,” it made a huge mess, as you would expect when blowing to smithereens an object at least 87 miles across (140 kilometers). But the movie’s mythology helpfully explains a hyperspace wormhole briefly opened, scattering much of the falling debris across the galaxy. As best as anyone can tell, a hyperspace wormhole has never appeared near Earth. And even if such a thing existed or happened, humans might not have the technology to chuck all our trash in there anyway. So we’re left with a whole lot of stuff all around us, including in space. According to the website Orbiting Now, in late April 2025 there were just over 12,000 active satellites orbiting the planet. All in all, the United States and other space-faring nations are trying to keep track of nearly 50,000 objects orbiting Earth. And there are millions of fragments of space debris too small to be observed or tracked. Just as on Earth’s roads, space vehicles crash into each other if traffic gets too congested. But unlike the debris that falls to the road after an Earth crash, all the bits and pieces that break off in a space crash fly away at speeds of several thousand miles per hour (10,000 to 30,000 kph) and can then hit other satellites or spacecraft that cross their paths. This accumulation of space debris is creating an increasing problem. With more satellites and spacecraft heading to orbit, and more stuff up there moving around that might hit them, space travel is becoming more like flying the Millennium Falcon through an asteroid field every day. Engineers at NASA, the European Space Agency and other space programs are exploring a variety of technologies – including a net, a harpoon and a laser – to remove the more dangerous pieces of space junk and clean up the space environment.

The Force itself

To most Earth audiences, the Force was a mysterious energy field created by life that binds the galaxy together. That is until 1999, when “Episode I: The Phantom Menace” revealed that the Force came from midi-chlorians, a microscopic, sentient life form that lives within every living cell. To biologists, midi-chlorians sound suspiciously similar to mitochondria, the powerhouse of our cells. The current working hypothesis is that mitochondria emerged from bacteria that lived within cells of other living things. And mitochondria can communicate with other life forms, including bacteria. There are many different kinds of mitochondria, and medical professionals are learning how to transplant mitochondria from one cell to another just like they transplant organs from one person’s body to another. Maybe one day a transplant procedure could help people find the light side of the Force and turn away from the dark side. May the Fourth – and the Force – be with you. Daniel B.
