Even if humankind manages to limit global warming to 2 degrees C (3.6 degrees F), as the Intergovernmental Panel on Climate Change recommends, future generations will have to deal with sea levels 12 to 22 meters (40 to 70 feet) higher than at present, according to research published in the journal Geology.
The researchers, led by Kenneth G. Miller, professor of earth and planetary sciences in the School of Arts and Sciences at Rutgers University, reached their conclusion by studying rock and soil cores in Virginia, Eniwetok Atoll in the Pacific and New Zealand. They looked at the late Pliocene epoch, 2.7 million to 3.2 million years ago, the last time the carbon dioxide level in the atmosphere was at its current level, and atmospheric temperatures were 2 degrees C higher than they are now.
“The difference in water volume released is the equivalent of melting the entire Greenland and West Antarctic Ice Sheets, as well as some of the marine margin of the East Antarctic Ice Sheet,” said H. Richard Lane, program director of the National Science Foundation’s Division of Earth Sciences, which funded the work. “Such a rise of the modern oceans would swamp the world’s coasts and affect as much as 70 percent of the world’s population.”
“You don’t need to sell your beach real estate yet, because melting of these large ice sheets will take from centuries to a few thousand years,” Miller said. “The current trajectory for the 21st century global rise of sea level is 2 to 3 feet (0.8 to1 meter) due to warming of the oceans, partial melting of mountain glaciers, and partial melting of Greenland and Antarctica.”
Miller said, however, that this research highlights the sensitivity of Earth’s great ice sheets to temperature change, suggesting that even a modest rise in temperature results in a large sea-level rise. “The natural state of the Earth with present carbon dioxide levels is one with sea levels about 20 meters higher than at present,” he said.
Miller was joined in the research by Rutgers colleagues James G. Wright, associate professor of earth and planetary sciences; James V. Browning, assistant research professor of earth and planetary sciences; Yair Rosenthal, professor of marine science in the School of Environmental and Biological Sciences; Sindia Sosdian, research scientist in marine science and a postdoctoral scholar at Cardiff University in Wales; and Andrew Kulpecz, a Rutgers doctoral student when the work was done, now with Chevron Corp. Other co-authors were Michelle Kominz, professor of geophysics and basin dynamics at Western Michigan University; Tim R. Naish, director of the Antarctic Research Center at Victoria University of Wellington, in New Zealand; Benjamin S. Cramer of Theiss Research in Eugene, Ore.; and W. Richard Peltier, professor of physics and director of the Center for Global Change Science at the University of Toronto.

RECENTLY, I’VE BEEN THINKING about something I wrote fourteen years ago, which has become one of my most quoted passages: “Every morning when I wake up I ask myself whether I should write, or blow up a dam.” Despite having faith in my work as a writer, I knew that it wasn’t a lack of words that was killing salmon in the Northwest. It was the presence of dams.
Since that time, things have gotten much worse for salmon, and for almost everything on the earth. By now we all know the numbers, or we should. Two hundred species per day driven extinct, 90 percent of the large fish in the oceans extirpated, more than 98 percent of native forests destroyed, 99 percent of prairies, and on and on. Virtually every biological indicator is pointing the wrong direction. Native communities—human and nonhuman—are under assault. Where I live, frog populations have collapsed, as have newt populations, butterfly populations, crane fly populations, dragonfly populations, banana slug populations, songbird populations. Crow populations have collapsed. Bat populations. Woolly bear populations. Moth populations. Bumblebee and solitary bee populations. And these are just some of the absences I’ve noticed. Salmon of course have continued to collapse. At this point I give salmon fifteen years. If we can bring down industrialized civilization in the next fifteen years, I think salmon, in time, will be fine. Much longer and they will not survive.
So where does writing fit in? Far too many of us have forgotten, or never knew, that words can be used as weapons in service of our communities. Far too many of us have forgotten, or never knew, that words should be used as weapons in service of our communities. For far too long, too many critics and teachers have told us that literature should be apolitical (as though this were possible), and that even nonfiction and journalism should be “neutral” or “objective” (as though this, too, were possible). If you want to send a message, they told us, use Western Union. I once spoke with a nature writer who refused to lend his name to a campaign to protect a species about whom he had written, giving as his reason, “I’m a writer. I have to remain neutral.”
When the world is being murdered, such a position is inexcusable. It is immoral. And it reveals a great ignorance for what it means to be a writer. Have these people never heard of Steinbeck, Dickens, Crane, Hugo? Charlotte Perkins Gilman? Rachel Carson? Frederick Douglass? Harriet Beecher Stowe? Alexandra Kollontai? George Eliot? Katharine Burdekin? Zora Neale Hurston? Andrea Dworkin? B. Traven? Upton Sinclair? A little Tolstoy, anyone?
I would not be who I am and I would not write what I write without having learned from some of my elders who refused to believe that writers should or can be apolitical or neutral or objective. The truth is most important, they said. It is more important than money. It is more important than fame. It is more important than your career. It’s more important than your preconceptions. Follow the truth—follow the words and ideas—wherever they lead. Words matter, they said. Art matters. Literature matters. Words and art and literature can change lives, and can change history. Make sure that your words and your art and your literature move people individually and collectively in the direction of justice and sustainability. They said literature that supports capitalism is immoral. A literature that supports patriarchy is immoral. A literature that does not resist oppression is immoral. But you can help to create a literature of morality and resistance, as each new generation must create this literature, with the help of all those generations who came before, holding their hands for support, just as those who come after will need to hold yours.
I was also taught that art can be and is and, to be moral, must be a combat discipline.
Recognizing that art can be a combat discipline is part of a process necessary for social change, but it’s not all of it. If too few of us remember that words can be weapons, even fewer of us remember that, as weapons, words cannot fight alone. Words themselves do not topple dictators, they do not stop capitalism, they do not stop oppression, they do not halt species extinction, they do not stop global warming, they do not remove dams. At some point someone actually has to do something. At some point someone needs to physically dismantle the infrastructures that allow capitalism to metastasize, oppression to continue, species extinction and global warming to accelerate, dictators and dams to stand.
That job is up to all of us.
A friend and mentor once asked me, “What are the largest, most pressing problems you can help to solve using the gifts that are unique to you in all the universe?” That question shows precisely where I have succeeded as a writer and human being, and precisely where I have failed.
There are many ways my writing life could so far be considered a success far beyond anything I daydreamed about when I was younger. I have twenty books out. People seem to enjoy reading them and coming to my talks, both of which honor me beyond belief. Despite the truth of the old cliché about writing, that it is a terrible way to make a living and a great way to make a life, for at least the last few years I’ve been able to financially support myself through writing. More important than all of these, however, is that I have been true to my muse, and have at least attempted to tell the truth as I have come to understand it. And I have sometimes succeeded in articulating some of those things I know in my heart to be true, and in so doing have, I hope, helped some others to articulate some of those things they may know in their hearts to be true.
This is all to the good. But the fact remains that if we judge my work, or anyone’s work, by the most important standard of all, and in fact the only standard that really matters, which is the health of the planet, my work (and everyone else’s) is a complete failure. Because my work hasn’t stopped the murder of the planet. Nor has anyone else’s. We haven’t even slowed it down. It’s embarrassing to have to explain why this is the only standard that really matters, but at this point embarrassment is the least of our problems. The health of the planet is the only standard that really matters because without a living planet nothing else is important, because nothing else exists. Compared to this, the number of books one has published doesn’t matter. How beautifully or poorly they are written doesn’t matter. Financially supporting oneself doesn’t matter. Life itself is more important than what we create.
These days when I wake up, I’m even less certain that my decision to write is the right one. I know that a culture of resistance needs every form of action, from writing to legal work to mass protests in the streets to physically dismantling destructive infrastructures. And that too few people are calling for actions that are commensurate with the threats to the planet. And so, for better or worse, most mornings, articulating the truth and defending it and rallying others to defend it in whatever ways they know how is the method of combat I choose.
The time for waiting is long gone. It is time to stop this culture from destroying life on earth. So take my hand. Take the hands of all those who came before us. But keep your other hand free, to make a fist or to pick up a pen. The health of the oceans, the forests, the rivers, the salmon, the sturgeon, the migratory songbirds, are all more important than you or I individually, and they are more important than your or my accomplishments. Their health will be the measure of our success.

High levels of pollution may be turning the planet’s oceans acidic at a faster rate than at any time in the past 300 million years, with unknown consequences for future sea life, researchers said Thursday.
The acidification may be worse than during four major mass extinctions in history when natural pulses of carbon from asteroid impacts and volcanic eruptions caused global temperatures to soar, said the study in the journal Science.
An international team of researchers from the United States, Britain, Spain, Germany and the Netherlands examined hundreds of paleoceanographic studies, including fossils wedged in seafloor sediment from millions of years ago.
They found only one time in history that came close to what scientists are seeing today in terms of ocean life die-off — a mysterious period known as the Paleocene-Eocene Thermal Maximum about 56 million years ago.
Though the reason for the carbon upsurge back then remains a source of debate, scientists believe that the doubling of harmful emissions drove up global temperatures by about six degrees Celsius and caused big losses of ocean life.
Oceans are particularly vulnerable because they soak up excess carbon dioxide from the air which turns the waters more acidic, a state that can kill corals, mollusks and other forms of reef and shell organisms.
“We know that life during past ocean acidification events was not wiped out — new species evolved to replace those that died off,” said lead author Barbel Honisch, a paleoceanographer at Columbia University’s Lamont-Doherty Earth Observatory.
“But if industrial carbon emissions continue at the current pace, we may lose organisms we care about — coral reefs, oysters, salmon.”
Honish and colleagues said the current rate of ocean acidification is at least 10 times faster than it was 56 million years ago.

A mind-boggling 40,000 trillion becquerels of radioactive cesium, or twice the amount previously thought, may have spewed from the crippled Fukushima No. 1 nuclear power plant after the March 11 disaster, scientists say.
Michio Aoyama, a senior researcher at the Meteorological Research Institute, released the finding at a scientific symposium in Tsukuba, Ibaraki Prefecture, on Feb. 28.
The figure, which represents about 20 percent of the discharge during the 1986 Chernobyl nuclear disaster, is twice as large as previous estimates by research institutions both in Japan and overseas.
It was calculated on the basis of radioactive content of seawater sampled at 79 locations in the north Pacific and is thought to more accurately reflect reality than previous simulation results.
Scientists believe that around 30 percent of the radioactive substances discharged during the crisis ended up on land, while the rest fell on the sea.
This makes it especially difficult to accurately evaluate the total amount of radioactive materials released. Thus, seaborne data is essential to the process.
The scientists measured cesium concentrations in seawater as of April and May last year. They then used a model of diffusion in the atmosphere and the oceans to evaluate the total amount of cesium released. The calculation produced estimates of 30-40 quadrillion becquerels.
The researchers also estimated that 24-30 quadrillion becquerels of that cesium reached the sea.
That combines the roughly 70 percent of the total discharge, which is thought to have reached the ocean, and the cesium content of radioactive water that Tokyo Electric Power Co., the nuclear plant operator, released from the plant to the sea.
While the latest study said 15-20 quadrillion becquerels of cesium-137 was released into the atmosphere, the Japan Atomic Energy Agency estimated the amount at 8.8 quadrillion becquerels. Similar data released by other researchers both in Japan and overseas ranged between 7 quadrillion and 35 quadrillion becquerels.
In the meantime, TEPCO on Feb. 28 began pouring cement on a trial basis from a marine platform onto the seabed in the port at the Fukushima No. 1 nuclear plant. The work is intended to cover 7 hectares of seabed inside the breakwaters.
The aim is to prevent radioactive cesium that accumulated there from spreading offshore. The project is expected to take 3-4 months to finish.
During the trial, TEPCO will determine what thickness of cement cover is effective for the purpose. Choppy waters due to adverse weather conditions had obstructed the work.
