In December 2010, 350.org coordinated a planet-scale art project, with many of the 20 works visible from satellites. In 2011 and 2012 he led the environmental campaign against the proposed Keystone XL pipeline project and spent three days in jail in Washington, D.C. Two weeks later he was inducted into the literature section of the American Academy of Arts and Sciences.
He was awarded the Gandhi Peace Award in 2013. Foreign Policy magazine named him to its inaugural list of the 100 most important global thinkers in 2009 and MSN named him one of the dozen most influential men of 2009. In 2010, The Boston Globe called him "probably the nation's leading environmentalist" and Time magazine book reviewer Bryan Walsh described him as "the world's best green journalist". In 2014, he was awarded the Right Livelihood Award for "mobilizing growing popular support in the USA and around the world for strong action to counter the threat of global climate change." In 2019, Aidan Smith, writing for Current Affairs, mentioned McKibbnen as a possible future Secretary of the Interior or Secretary of Energy in the cabinet of a hypothetical future progressive President.
Early life Bill McKibben was born in Palo Alto, California. His family later moved to Lexington, Massachusetts, where he attended high school. His father, who once, in 1971, had been arrested during a protest in support of Vietnam veterans against the war, wrote for Business Week, before becoming business editor at The Boston Globe, in 1980. As a high school student, McKibben wrote for the local paper and participated in statewide debate competitions. Entering Harvard College in 1978, he became an editor of The Harvard Crimson and was chosen president of the paper for the calendar year 1981.
In 1980, following the election of Ronald Reagan, he determined to dedicate his life to the environmental cause.
Graduating in 1982, he worked for five years for The New Yorker as a staff writer, writing much of the Talk of the Town column from 1982 to early 1987. Inspired by the Gospel of Matthew, he became an advocate of nonviolent resistance. While doing a story on the homeless, he lived on the streets; there, he met his wife, Sue Halpern, who was working as a homeless advocate. In 1987, McKibben quit The New Yorker after longtime editor William Shawn was forced out of his job. He and his family shortly after moved to a remote spot in the Southeastern Adirondacks of upstate New York, where he began to work as a freelance writer.
Writing McKibben began his freelance writing career at about the same time that climate change appeared on the public agenda following the hot summer and fires of 1988 and testimony by James Hansen before the United States Senate Committee on Energy and Natural Resources in June of that year. His first contribution to the debate was a brief list of literature on the subject and commentary published December 1988 in The New York Review of Books and a question, "Is the World Getting Hotter?"
He became and remains a frequent contributor to various publications, including The New York Times, The Atlantic, Harper's, Orion, Mother Jones, The American Prospect, The New York Review of Books, Granta, National Geographic, Rolling Stone, Adbusters, and Outside. He is also a board member at and contributor to Grist.
His first book, The End of Nature, was published in 1989 by Random House after being serialized in The New Yorker. Described by Ray Murphy of the Boston Globe as a "righteous jeremiad", the book excited much critical comment, pro and con; was for many people their first introduction to the question of climate change;Aulakh, Raveena (July 5, 2015). "Gentle climate warrior turns up the heat". Toronto Star. and the inspiration for a great deal of writing and publishing by others. It has been printed in more than 20 languages. Several editions have come out in the United States, including an updated version published in 2006.
In 1992, The Age of Missing Information was published. It is an account of an experiment in which McKibben collected everything that came across the 100 channels of cable TV on the Fairfax, Virginia, system (at the time among the nation's largest) for a single day. He spent a year watching the 2,400 hours of programming, and then compared it to a day spent on the mountaintop near his home. This book has been widely used in colleges and high schools and was reissued in a new edition in 2006.
Subsequent books include Hope, Human and Wild, about Curitiba, Brazil, and Kerala, India, which he cites as examples of people living more lightly on the earth; The Comforting Whirlwind: God, Job, and the Scale of Creation, which is about the Book of Job and the environment; Maybe One, about human population; Long Distance: A Year of Living Strenuously, about a year spent training for endurance events at an elite level; and Enough, about what he sees as the existential dangers of genetic engineering and nanotechnology. Speaking about Long Distance at the Cambridge Forum, McKibben cited the work of Mihaly Csikszentmihalyi and Csikszentmihalyi's idea of "flow" relative to feelings McKibben had had—"taking a break from saving the world", he joked—as he immersed himself in cross-country skiing competitions."Cambridge Forum" , via Maine Public Broadcasting Network (radio), September 14, 2011 12:30 pm.

Wandering Home is about a long solo hiking trip from his home in the mountains east of Lake Champlain in Ripton, Vermont, back to his longtime neighborhood in the Adirondacks. His book Deep Economy: the Wealth of Communities and the Durable Future, published in March 2007, was a national bestseller. It addresses what he sees as shortcomings of the growth economy and envisions a transition to more local-scale enterprise.
In fall 2007, he published, with members of his Step It Up team, Fight Global Warming Now, a handbook for activists trying to organize their local communities. In 2008, came The Bill McKibben Reader: Pieces from an Active Life, a collection of essays spanning his career. Also in 2008, he edited for Library of America the anthology, American Earth: Environmental Writing Since Thoreau. In 2010, he published another national bestseller, Eaarth: Making a Life on a Tough New Planet, an account of the rapid onset of climate change. It was excerpted in Scientific American.
In 2019, McKibben published Falter: Has the Human Game Begun to Play Itself Out?, which details the growing concerns over climate change, how the Koch Brothers are contributing to an increase in carbon emissions by funding oil companies, and his concern with libertarianism, which he argues was sparked by the politics of the Reagan Revolution. He frequently argues that the Nordic model is preferable to a deregulated capitalist system, and that rapid innovation may come to hurt humanity.
In 2022, he published two books. We Are Better Together is a picture book for children celebrating the power of human cooperation and the beauty of life on Earth, illustrated by artist Stevie Lewis. The Flag, the Cross, and the Station Wagon: A Graying American Looks Back at His Suburban Boyhood and Wonders What the Hell Happened is a personal memoir that also digs into America's history to reflect on what has brought us to the present environmental crisis.
Some of McKibben's work has been extremely popular; an article in Rolling Stone in July 2012 received over 125,000 likes on Facebook, 14,000 tweets, and 5,000 comments.
McKibben was the guest editor of the 2024 edition of The Best American Science and Nature Writing anthology.
His book, "Here Comes The Sun," was published in 2025. The book's theme is that renewable energy prices are falling rapidly, and, as the title suggests, so are solar prices. The book is named after the Beatles' song, "Here Comes the Sun." In that book, he writes in the introduction: "We are on the verge of turning to the heavens for energy instead of to hell."
Environmental campaigns
Step It Up Step It Up 2007 was a nationwide environmental campaign, organized by McKibben, to demand action on global warming by the U.S. Congress.
In late summer 2006 he helped lead a five-day walk across Vermont to call for action on global warming. Beginning in January 2007, he founded Step It Up 2007, which organized rallies in hundreds of American cities and towns on April 14, 2007, to demand that Congress enact curbs on carbon emissions by 80 percent by 2050. The campaign quickly won widespread support from a wide variety of environmental, student, and religious groups.
In August 2007, McKibben announced Step It Up 2, to take place November 3, 2007. In addition to the 80% by 2050 slogan from the first campaign, the second adds "10% [reduction of emissions] in three years ("Hit the Ground Running"), a moratorium on new coal-fired power plants, and a Green Jobs Corps to help fix homes and businesses so those targets can be met" (called "Green Jobs Now, and No New Coal").
350.org
In the wake of Step It Up's achievements, the same team announced a new campaign in March 2008 called 350.org. The organizing effort, aimed at the entire globe, drew its name from climate scientist James E. Hansen's contention earlier that winter that any atmospheric concentration of carbon dioxide (CO2) above 350 parts per million was unsafe. "If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current 385 ppm to at most 350 ppm, but likely less than that." Hansen et al. stated in the Abstract to their paper.Hansen, J., Mki. Sato, P. Kharecha, D. Beerling, R. Berner, V. Masson-Delmotte, M. Pagani, M. Raymo, D.L. Royer, and J.C.
