In addition to accelerating efforts to reduce global carbon emissions to reverse global warming, governments must urgently adopt strong, permanent protections for the entire Arctic Ocean.
On World Ocean Day, and the eve of the United Nations Ocean Conference in Nice, France opening Monday, the Arctic Ocean ecological crisis needs to be top of the list for attention by governments.
Given the well-documented, catastrophic decline of the Arctic Ocean sea ice ecosystem in recent decades due to climate change, coupled with the increasing threats and impacts from industry and military activity in the region, it is imperative that governments establish an International Arctic Ocean Sanctuary to preserve this extraordinary ecoregion as a global commons for peaceful, non-commercial, scientific purposes.
Covering approximately 5.4 million square miles, the Arctic Ocean is one of the most extraordinary and vibrant regions of the global ocean, and plays an important role regulating Earth’s climate.
Combined with the effects of climate change, industrialization and militarization would further accelerate the ecological and social collapse of the struggling Arctic Ocean region.
The Arctic marine ecosystem is globally unique, productive, and remains relatively unexplored. The ocean biome supports more than 7,000 identified species, many of which are found nowhere else on Earth—polar bears, walrus, several kinds of ice seals, narwhals, beluga whales, bowhead whales, some of the largest populations of seabirds in the world, and many unique fish and invertebrate populations. It hosts cold seeps, hydrothermal vents, stunning benthic habitats, a rich pelagic ecosystem that remains surprisingly active during winter darkness, and supports the subsistence cultures of coastal Indigenous Peoples.
However, this unique polar marine ecosystem is now one of the most endangered regions of Earth’s biosphere, suffering effects of climate change more severely than anywhere else. Arctic sea ice has declined by more than half in the last 50 years, losing about 1 million square milesin both summer and winter, has thinned from an average of four meters to about one meter, and could disappear entirely in summer by 2035. Multiyear sea ice has all but vanished. This remarkable decline has been caused by global carbon emissions from human activity, mainly fossil fuel use.
The loss of Arctic sea ice over the last half-century constitutes one of the largest declines in ecological habitat on Earth, rivaling the loss of tropical rainforests. The resultant Arctic Ocean ecological crisis is now severe, and predicted to get much worse in coming decades.
In addition to devastating impacts of climate change in the Arctic Ocean, commercial interests are clamoring to exploit ice-free offshore areas for oil and gas, methane hydrates, minerals, commercial fishing, shipping, and tourism. And Arctic coastal nations have made Extended Continental Shelf (ECS) seabed claims (pursuant to U.N. Law of the Sea, Article 76) beyond their 200-mile Exclusive Economic Zones (EEZs), a dangerous territorial expansion into international waters with an eye toward resource extraction.
As Arctic nations and others (China, India, etc.) advance their own parochial interests across the region, there is a growing competitive race to exploit Arctic offshore resources and to project military power across the region to secure these competing national interests. As such, the risk of military confrontation across the Arctic Ocean is escalating. Combined with the effects of climate change, industrialization and militarization would further accelerate the ecological and social collapse of the struggling Arctic Ocean region, and would clearly compromise the ability of the bioregion and its people to survive the 21st-century climate crisis.
In fact, the resource and political tensions in the Arctic Ocean today are remarkably similar to the Antarctic after World War II, that were resolved then by the leadership of U.S. (Republican) President Dwight D. Eisenhower proposing and negotiating the historic 1959 Antarctic Treaty. The international Treaty, now with 58 nation-state members, permanently protects the extraordinary 5.5 million square-mile Antarctic continent as a global commons for peaceful, scientific purposes, free from nuclear testing, military operations, economic exploitation, and territorial claims. The Antarctic Treaty remains the single greatest conservation achievement in history.
The same opportunity now presents itself with the Arctic Ocean. In addition to accelerating efforts to reduce global carbon emissions to reverse global warming, governments must urgently adopt strong, permanent protections for the entire Arctic Ocean to give this region and its people the best chance possible to survive the 21st-century climate crisis. Given the pace of decline, this may be our last best chance to do so.
While Arctic nations have begun protecting some areas off their coasts, still less than 5% of Arctic Ocean waters are in permanently protected status. This is clearly insufficient.
The proposed circumpolar Arctic Ocean Sanctuary must fully protect not only international waters beyond coastal state 200-mile EEZs across the 1.1 million square mile Central Arctic Ocean (as is currently proposed), but also the highly productive waters within the EEZs of Arctic coastal nations—Canada, Norway, Denmark and Greenland, Russia, and the U.S., where most ecological activity, human impact, and threat occurs. The sanctuary should permanently prohibit oil and gas leasing, mineral leasing, commercial fishing, military activities, improve shipping safety, reduce pollutants, and enhance scientific research.
To be sure, it is a big ask of the five Arctic coastal nations to contribute some of their claimed territory into a globally protected area, but this was the right thing to do in 1959 in the Antarctic, and it is the right thing to do now for the Arctic.
While the current federal administrations in the Russia and U.S. habitually oppose any and all environmental conservation proposals, perhaps presidents Vladimir Putin and Donald Trump might see this as a historic legacy in the midst of the environmental havoc they have caused, a chance to be remembered as Eisenhower is today for his leadership in negotiating the Antarctic Treaty. And just to note, former President Joe Biden ignored this request entirely, enacted no comprehensive permanent protections in the U.S. Arctic Ocean off Alaska, and made no effort to begin discussions on the International Arctic Ocean Sanctuary.
Global society has a historic choice to make with the imperiled Arctic Ocean. Should we continue our competitive industrial and military expansion into one of the last wild areas of the world, further degrading a region already unraveling due to human-caused climate change? Or should we protect and sustain this magnificent place for all time, giving it and its inhabitants, human and non-human, the best chance possible to recover from climate change this century?
How we answer this question will tell us a lot about ourselves and our future.
In sliding too close to the regime that now attacks them, too many universities have lost much of the leverage needed to marshal wider public support for their most noble agendas.
Universities face vitriolic attacks today from the Trump regime. Several could even go under. When you keep in mind that he also targets other institutions of civil society—such as law firms, labor unions, the media, assorted churches, and the like—it becomes woefully clear what is going on.
The Trump regime seeks to force all independent sources of news, truth, and judgment to their knees, doing so to rapidly impose a fascist oligopoly that limits and demeans every orientation and viewpoint except his own. His is a recipe most autocratic regimes introduce early in the day. As M. Gessen has reminded us in a superb piece in the New York Times, the silencing of diverse centers of judgment and opinion marks the early stages of an authoritarian movement. I quote from her experience in Russia during the middle stages of the Putin takeover:
"I was shaken when Russian invaded Georgia in 2008. My world change when three young women were sentenced to jail for a protest in a church in 2012, the first time Russian citizens were imprisoned for peaceful action. I couldn't breathe when Russian annexed Crimea in 2014. And when the opposition leader Alexei Navalny was posoned in 2020, arrested in 2021, and almost killed in prison in 2024. And when Russian invaded Ukraine in 2022." (NYT, June 1, 2025, p B4).
The Gessen message is that it is unwise and dangerous to first feel shocked by such events and then allow them to become absorbed into the new background of life. If Trump has not yet made the same moves as Putin, his Big Lies, pardons of hundreds of convicted insurrectionists, attacks on independent centers of civil society, and extra-legal exportation of people to concentration camps in other countries are well on the way. We are shocked at each new round and then tend to forget how shocking such events were.
It is unwise and dangerous to first feel shocked by such events and then allow them to become absorbed into the new background of life.
So, the first thing universities and colleges must do today is to join hands with other institutions of civil society which are—or are about to—face the same sort of massive pressures, pressures often backed by militia threats to the livelihoods and safety of people in those same institutions. That is exactly why Trump, very early, pardoned the militias who joined him in drives to deny and violently overturn the results of the 2020 election. He may well need them in the future. "Stand back and stand by." It is also why Inspector Generals were immediately removed from key institutions in the government and why Elon Musk was given free rein to wreak havoc on government institutions focused on health for the poor, medical studies, and new scientific research.
It must be emphasized from the start, too, how fraudulent new movements are within several universities—led, I fear, by the one in which I have worked—to "pluralize" intellectual perspectives within their schools. It is now called "Viewpoint Diversity." Those are attempts to move universities toward the right of the current distribution of power and opinion while the right itself holds bankrupt views about future dangers and possibilities. The fraudulence of this movement is easy to expose: If you campaign to move university faculty to the right in the name of institutional pluralism, why not—with the same vociferousness—call for greater economic and ideological diversity among university trustees, university presidents, corporate boardrooms, right wing think tanks, silicon valley entrepreneurs, the Claremont Institute, and Fox News reporting? For surely, these institutions on the right could use more diversity. The reason is that the so carefully selected calls for diversity within universities alone are designed to draw university culture—as one of the precarious holdouts against an autocratic regime—more securely into the orbit of that regime. Greater faculty "diversity," neoliberal university administrations, and external pressure will do the job.
Neoliberal university presidents and trustees may not love aspects of the Trump agenda, but too many show by their deeds that they prefer it to a university in which faculty control the curriculum, bloated administrative staffs are reduced, students express political opinions freely, and peaceful protests are treated as welcome aspects of university life that can educate wider publics about things many had failed heretofore to grasp. There have been valuable university challenges to public opinion to reconsider the Vietnam War, to resist the Iraq War, to ignite civil rights, to challenge Israeli genocide in Gaza, and to come to terms with an emerging period of climate wreckage that corporate/state institutions now try to ignore, downplay, or cover up.
So, what should universities and colleges be doing today, then? Well, first, we must relieve our decades long great dependence on the state by curtailing military research. Faculties, students, and parents must also band together to demand a pluralization of boards of trustees, as we pull back the autocratic powers too many university and college presidents have assumed in recent years. More than that, faculties, students, and ecologists must demand that more teaching and research resources be devoted to studying the dangers radical climate wreckage poses to life in so many regimes today. (I note that this has never been one of the "signature" initiatives pursued by the president of my university, though he loves AI research).
As it becomes clear how current hurricane and tornado surges, wildfires, faster glacier melts, ocean rises, and a slowing ocean conveyor are harbingers of worst to come unless radical transformations are undertaken, university humanists, earth scientists, and social scientists must find new ways to work together. While some schools lead the way in this regard, many others are populated by faculties and students who would also give climate wreckage their highest teaching and research priority if only their trustees, provosts, and presidents would stop discouraging and marginalizing these activities. Too many of the latter are too close for comfort to Trump in this regard
These are all big and risky moves. They will incite further Trump attacks as they focus on an accelerating condition he calls "climate crap." And yet, much more is needed, too. Universities must make themselves into living eco-egalitarian beacons today, doing so to encourage other institutions of civil society to follow suit. Most faculty know that today university presidents, deans, and college coaches too often pull down extravagant salaries and benefits. Those perks often draw their lifestyles and thinking closer to big neoliberal donors who increasingly see themselves inhabiting a different world from people in everyday life. This encourages college presidents to mimic the lifestyles of the donor class and to downplay the educational needs of the poor, racial minorities, and future high school teachers. The current structure of the university is exquisitely designed to foment working-class resentments among those who know their kids need to go to college but can't afford the exorbitant bill to do so.
Let the university not only practice affirmative action in admissions—an affirmative action that must now encompass class as well as race and gender—but itself become a living beacon of a more egalitarian way of being.
So, let's work to usher into being student/faculty/parent/movements to demand that the highest paid members of a university make, say, no more than eight times as much as the lowest paid members—the food staff, the janitors, the support staff, the groundskeepers, etc. Let the university not only practice affirmative action in admissions—an affirmative action that must now encompass class as well as race and gender—but itself become a living beacon of a more egalitarian way of being. One immediate effect will be to lower the cost of admission for working-class students.
These egalitarian practices must be joined to a variety of ecological practices, practices which enact in college organization what ecologists know are urgently needed in the wider society too. The university will now become a center in which fossil fuels are a thing of the past, replaced by solar and wind power. Its new buildings—hopefully now emphasizing the classroom buildings that are sorely needed—will also be constructed to conform to the most advanced ecological designs. Such redesigns can draw upon faculty and students from multiple fields to participate in their perfection.
Of course, it will be announced immediately that these are all utopian proposals. They are sooo unrealistic. They are indeed. In being utopian they not only expose how right-wing, anti-egalitarian, and anti-ecological the Trump regime is today. They also show how too many university presidents and trustees have lost their way as well, adopting modes of realism woefully inadequate to the risks faced today by universities and the larger society. University leaders often assume they can float above the inequalities and climate wreckage of today, and they too often support a university matrix that is desperately unattuned to the most urgent needs of the larger society in which they are nested. In sliding too close to the regime that now attacks them, too many universities have lost much of the leverage needed to marshal wider public support for their most noble agendas.

Under a new, or revivified, university regime, presidents, provosts and deans--albeit a much smaller cohort than the number which currently bloats these schools—will propose agendas to the faculty rather than imposing them from above and waiting for laggards to buy into their problematic neoliberal image of the world. They will enact democratic processes rather than putting the squeeze on faculty, students, and parents from every side.
When it comes to Harvard against Trump and Musk, the faculty must always side with Harvard. When it comes to the current authoritarianism of too many university presidents, provosts, deans, and trustees, more faculty members must call upon a new generation of students, faculty and parents to repair the damage collaborating university regimes have wrought both in their internal organization and in the public face they present to society. We must speak more vociferously to a wider public about the real situation the United States faces, as its autocratic leaders attack democracy, affirm racism, accelerate inequality, flirt with economic disaster, ignore climate wreckage, and refuse to acknowledge how their own climate policies help to promote the escalating migrations from south to north they so cruelly use to foment fascist energies at home. The odds, of course, are against those who seek to make the university a new center of egalitarian creativity and ecological awareness. But since the most likely alternative to that is disaster, those are the odds we must face and strive to overcome.
Scientists said that atmospheric carbon dioxide concentrations peaked above 430 parts per million for the first time in perhaps 30 million years.
The concentration of carbon dioxide in the atmosphere peaked above 430 parts per million in 2025—the highest it has been in millions of years—according to data released by the National Oceanic and Atmospheric Administration and Scripps Institution of Oceanography at the University of California, San Diego on Thursday.
The news was overshadowed by the explosive feud between U.S. President Donald Trump and his erstwhile backer Elon Musk, but climate activist Bill McKibben argued that it was ultimately more consequential.
"In the long run, this is actually going to be the important news of the day—CO2 in the atmosphere passes another grim milestone," McKibben wrote on social media.

Carbon dioxide has been accumulating in the atmosphere due primarily to the human burning of fossil fuels, as well as by the clearing of forests and other natural carbon sinks. There, it acts as a greenhouse gas, trapping heat from the Earth, and is the primary gas responsible for the rise of global temperatures by approximately 1.1°C from the 1850 -1900 average. This warming has already had a host of dramatic impacts, from extreme weather events to sea-level rise to polar ice melt, and scientists warn these impacts will only accelerate under current energy policies, which put the world on track for around 3°C of warming by 2100.
The last time that atmospheric CO2 concentrations topped 430 ppm was most likely more than 30 million years ago, Ralph Keeling, who directs the Scripps CO2 Program, toldNBC News.
"It's changing so fast," he said. "If humans had evolved in such a high-CO2 world, there would probably be places where we wouldn't be living now. We probably could have adapted to such a world, but we built our society and a civilization around yesterday's climate."
"While largely symbolic, passing 430 ppm should be a wake-up call."
Scripps and National Oceanic and Atmospheric Administration both measure carbon dioxide levels from NOAA's Mauna Loa Observatory in Hawaii, where Charles Keeling began taking measurements in 1958. As CO2 levels rise over time, they also follow a seasonal cycle—peaking in May before falling in the Northern Hemisphere summer and rising again in the fall.
This May, Scripps Oceanography calculated an average of 430.2 ppm for 2025, which is 3.5 ppm over the average for May 2024. NOAA's Global Monitoring Laboratory, meanwhile, calculated a monthly average of 430.5 ppm, a 3.6 ppm jump from the year before and the second-steepest yearly climb since 1958.
"Another year, another record," Keeling said in a statement. "It's sad."
The news comes two months after Mauna Loa daily measurements surpassed 430 ppm for the first time in March, which Plymouth Marine Laboratory professor Helen Findlay called "extremely disappointing and worrying."
"While largely symbolic, passing 430 ppm should be a wake-up call, especially given the accelerated response we are seeing of glaciers and ice sheets to current warming," Dr. James Kirkham, chief scientist of the Ambition on Melting Ice coalition of governments, said at the time.
"This upward trajectory is a direct result of continued fossil fuel use, likely exacerbated by emissions from extreme wildfires last year, methane leaks from fossil fuel extraction and possibly greater permafrost emissions, alongside decreased ability of very warm oceans to absorb CO2," Kirkham said.
The monthly record also comes a little more than a week after a United Nations report warned that there was a small chance global temperatures could surpass 2°C in at least 1 of the next 5 years, only a decade after world leaders pledged in the Paris agreement to keep global temperatures "well-below" that level.
"Carbon emissions are still rising, and the atmosphere is going to keep heating further until greenhouse gas concentrations stabilize," Matt Kean, who chairs Australia's Climate Change Authority, wrote in response to the Scripps and NOAA figures. "What sort of climate do we want to leave our children and those who come after them?"
