It’s easy to feel pessimistic when scientists around the world are warning that climate change has advanced so far, it’s now inevitable that societies will either transform themselves or be transformed. But as two of the authors of a recent international climate report, we also see reason for optimism.
The latest reports from the Intergovernmental Panel on Climate Change discuss changes ahead, but they also describe how existing solutions can reduce greenhouse gas emissions and help people adjust to impacts of climate change that can’t be avoided.
The problem is that these solutions aren’t being deployed fast enough. In addition to push-back from industries, people’s fear of change has helped maintain the status quo.
To slow climate change and adapt to the damage already underway, the world will have to shift how it generates and uses energy, transports people and goods, designs buildings and grows food. That starts with embracing innovation and change.
Fear of change can lead to worsening change
From the industrial revolution to the rise of social media, societies have undergone fundamental changes in how people live and understand their place in the world.
Some transformations are widely regarded as bad, including many of those connected to climate change. For example, about half the world’s coral reef ecosystems have died because of increasing heat and acidity in the oceans. Island nations like Kiribati and coastal communities, including in Louisiana and Alaska, are losing land into rising seas.
Residents of the Pacific island nation of Kiribati describe the changes they’re experiencing as sea level rises.
Other transformations have had both good and bad effects. The industrial revolution vastly raised standards of living for many people, but it spawned inequality, social disruption and environmental destruction.
People often resist transformation because their fear of losing what they have is more powerful than knowing they might gain something better. Wanting to retain things as they are – known as status quo bias – explains all sorts of individual decisions, from sticking with incumbent politicians to not enrolling in retirement or health plans even when the alternatives may be rationally better.
This effect may be even more pronounced for larger changes. In the past, delaying inevitable change has led to transformations that are unnecessarily harsh, such as the collapse of some 13th-century civilizations in what is now the U.S. Southwest. As more people experience the harms of climate change firsthand, they may begin to realize that transformation is inevitable and embrace new solutions.
A mix of good and bad
The IPCC reports make clear that the future inevitably involves more and larger climate-related transformations. The question is what the mix of good and bad will be in those transformations.
If countries allow greenhouse gas emissions to continue at a high rate and communities adapt only incrementally to the resulting climate change, the transformations will be mostly forced and mostly bad.
For example, a riverside town might raise its levees as spring flooding worsens. At some point, as the scale of flooding increases, such adaptation hits its limits. The levees necessary to hold back the water may become too expensive or so intrusive that they undermine any benefit of living near the river. The community may wither away.
The riverside community could also take a more deliberate and anticipatory approach to transformation. It might shift to higher ground, turn its riverfront into parkland while developing affordable housing for people who are displaced by the project, and collaborate with upstream communities to expand landscapes that capture floodwaters. Simultaneously, the community can shift to renewable energy and electrified transportation to help slow global warming.
Optimism resides in deliberate action
The IPCC reports include numerous examples that can help steer such positive transformation.
For example, renewable energy is now generally less expensive than fossil fuels, so a shift to clean energy can often save money. Communities can also be redesigned to better survive natural hazards through steps such as maintaining natural wildfire breaks and building homes to be less susceptible to burning

Land use and the design of infrastructure, such as roads and bridges, can be based on forward-looking climate information. Insurance pricing and corporate climate risk disclosures can help the public recognize hazards in the products they buy and companies they support as investors.
No one group can enact these changes alone. Everyone must be involved, including governments that can mandate and incentivize changes, businesses that often control decisions about greenhouse gas emissions, and citizens who can turn up the pressure on both.
Transformation is inevitable
Efforts to both adapt to and mitigate climate change have advanced substantially in the last five years, but not fast enough to prevent the transformations already underway.
Doing more to disrupt the status quo with proven solutions can help smooth these transformations and create a better future in the process.
A golden tray sits on the Resolute Desk as President Donald Trump speaks during an announcement on American nuclear innovation in the Oval Office at the White House on July 24, 2026, in Washington, D.C. Trump is signing multiple executive orders targeting the nuclear energy sector and easing rules for new reactors and nuclear fuel supply chains.
Trump’s hubris rivals the fallen heroes of ancient Greek mythology
In January, the New York Times asked President Donald Trump if there were any limits on his global powers.
“Yeah,” the president responded, “there is one thing. My own morality. My own mind. It’s the only thing that can stop me.”
That was eight months ago, but fortunately Christopher Nolan’s blockbuster adaptation of “The Odyssey” has made ancient Greek literature newly relevant. Before that window closes, I’d like to talk about hubris.
Today, the term mostly means excessive pride or arrogance. That’s part of what the Greeks meant by it too, but the meaning was a bit richer and more specific. Hubris was an insolent or outrageous act that offended the gods, often because the transgressor was claiming abilities or authorities that solely belonged to supreme beings.
Nolan renamed and slightly modified the concept of xenia for the film, calling it “Zeus’ law.” In the director’s telling, mortals should follow the rules laid out by the gods, specifically the requirement to treat strangers with respect lest they be gods in disguise.
In a sense, hubris is the opposite, or at least the rejection, of xenia. The hubris of the suitors, and at times Odysseus himself, invites punishment by the gods and their mortal instruments.
Which brings me back to Donald Trump. His claim that there are no constraints on his personal power to dictate events on the global stage was one of the greatest expressions of hubris ever uttered by a political leader.
Trump’s claim was obviously false when he made it.
He vowed that he could end the Russia-Ukraine war in 24 hours. He’s proved powerless to make that happen. If he had divine powers to work his will, why would he have balked at implementing his tariffs so often that Wall Street adopted the “TACO trade” term for his deals? “TACO” stands for “Trump always chickens out.”
And why would Trump have made so many embarrassing concessions to China — from rescinding tariffs on Chinese goods to allowing them to buy crucial and incredibly valuable computer chips?
But Trump saw his success at capturing Venezuelan strongman Nicolas Maduro as proof of his ability to launch missiles to the same effect as Zeus’ lightning bolts. Trump believed he was the most powerful man who ever lived.
This is no exaggeration. In March, when the Iran invasion seemed successful, Trump gave a document penned by“Presidential Historian David King” to New York Times reporters Maggie Haberman and Jonathan Swan purporting to prove that Trump was “the most powerful person to have EVER walked this planet.” King was, in fact, a businessman and occasional caddy for legendary golfer Gary Player.
King compared Trump favorably to many of history’s most powerful, and often heinous, figures: Alexander the Great, Attila the Hun, William the Conqueror, Napoleon Bonaparte, Joseph Stalin, Genghis Khan, Mao Tse Tung, Adolf Hitler and Vladimir Lenin. Many of these men thought they were the most powerful person in the world, too. And many were defeated precisely because they believed it.
At least Napoleon and Hitler had a string of truly impressive victories before they learned the folly of hubris. The limits on Trump’s power have been exposed by far less august forces than the combined might of the allies in World War II or the fearsome Russian winter.
Iran is a comparatively middling power. But the regime’s ability to absorb punishment while imposing its will on the Strait of Hormuz has proved to be a greater constraint on Trump’s power than his morality or mind. We should note that, at least rhetorically, his morality has not proved much of a constraint. He has repeatedly promised to destroy Iranian “civilization” if the regime refuses to capitulate.
But they haven’t — and won’t anytime soon — because the regime’s tolerance for pain far outstrips Trump’s. The combined fear of skyrocketing oil prices, outrage of Gulf state potentates, diminishing weapon supplies and domestic unpopularity is doing the work that international law, congressional oversight and the collective opinion of foreign policy experts can’t or won’t do.
If I considered Trump more heroic than reason and facts could allow, I would say his Sisyphean predicament has the whiff of Greek tragedy to it. Trump is vexed by the fact that the Iranians won’t honor deals or ratify his countless premature claims of victory — giving new meaning to his vow that his presidency would make people tired of winning. It’s almost like they’re out-Trumping Trump.
Things might have gone better if he’d heeded that great Greek tragedian Sophocles: “For Zeus utterly abhors the boasts of a proud tongue.”
