Life lessons on Maya Mountain

Life lessons on Maya Mountain

Solastalgia – 1. A feeling of loss at demise of Earth; mourning for Gaia; profound ennui.
2. Lost connection to nature; an eco-psychological imbalance.
Antidotes: Ecological restoration
Permaculture

IMG_2154

So begins Albert Bates in his introduction to permaculture – a design system whose name originated from the idea of “permanent agriculture” and evolved into a system promoting permanence in the human culture itself.

“Solastalgia is what happens when we find that we are one of the only animals that soils its own nest, and then lives in it. Then we get sad and depressed,” he says. “We ask ourselves, ‘Can we survive?’”

Bates, a founder of the Global Ecovillage Network and a prolific author and public speaker, has made his way through miles of Mayan villages and tropical forest to Maya Mountain Research Farm in southern Belize, as he does every March. It’s part of a hectic schedule that has him traveling all over the globe, from Estonia to the Holy Lands and beyond, preparing willing participants for what he calls The Great Change: a transition to a world less dependent on petroleum and other carbon-based fuels, and more in harmony with the Earth.

An integral part of his lesson plan is permaculture. Developed by Australians Bill Mollison and David Holmgren, permaculture has grown into a global movement, an approach to sustainable development that strives to work with nature instead of at cross purposes with it. Today, he and Mexican permaculture leader Maria Ros are giving us an intro to the principles of the system. But first, Bates administers a little shock therapy – a collection of seemingly random facts that all add up to a wakeup call for a hypnotized nation.
In 2008, he tells us, “USAnians” – he refuses to submit to the convention that has expropriated the name of the whole New World for the sole use of one country – purchased 68 million vehicles, 85 million refrigerators and 1.2 billion mobile phones. The average European consumes 43 kilograms of resources per person, while the average American consumes 88.

“If we used as much energy per capita as Europeans, we’d be an oil-exporting nation,” he tells us. At this point, the richest 7% – most of whom live in the US – produce 50% of the carbon.

It might not matter, he says, except that our acquisitive ways are driving the planet to the brink of destruction.
One-third of the world’s largest rivers are losing water 2½ times faster than they gain it; they are drying up. 150 villages in Northern Syria have been abandoned due to drought. The same thing is beginning to happen in Mexico, Africa and southern Spain.

“Whole villages are having to pack up and leave. Where are they going to go?”

Desertification, increasing frequency and intensity of hurricanes, disappearing water supplies and rising sea levels are expected to produce an estimated 1 billion environmental refugees by 2050.

“We’re in a cycle we created half a century ago that’s still unfolding,” he said. “The carbon from muscle cars of the ‘50s and the industrial plants of the ‘60s and ‘70s are still making their way into the atmosphere, going through chemical changes.

“We need a shift in human design.”

IMG_2253

Permaculture strives to use “more observation, less perspiration” by studying the lay of the land and the patterns of nature and working with them to create a harmonious design. The objective, he says, is to make oneself obsolete; in a good design, “the designer becomes the recliner.”

That’s why the hammock is an essential part of a good permaculture design, he maintains – although with his busy schedule, I’m having a hard time imagining him doing much hammock reclining.

“We have to ask ourselves: Can nature do it for us? Can we go with the flow? What is the flow?”

The three key principles, he says, are Earth care, people care and surplus share. That last part caught my attention. “If you don’t share the surplus, it becomes pollution,” he said, using as an example the fruit from an apple tree. Shared, it becomes a resource; left to spoil on the ground, it becomes a mess. The same holds true for any surplus production, he says. I imagine how different the world would be if sharing surplus were to become a part of the general ethic.

In fact, before the invention of money some 500 to 1,000 years ago, that was the case, he says. Early tribal people like the Cahokians created great trading centers that stretched from Nova Scotia and Alaska to the tropics, but trade was based on a friendly exchange, and hoarding wasn’t a useful behavior.

Alternative and local currencies have been developed in recent years, giving greater emphasis to the trust-building component of building a local economy. One recent example is the Totnes Pound, created in Devon, England, as a part of the first Transition Town, a movement that is now gaining ground throughout the world.

Bates talked of many things: the process of personal change, the first step in social change; the principles of permaculture, which draws on concepts like biomimicry and stacking functions; and Peace Through Permaculture, a program that has brought together Israelis and Palestinians in innovative initiatives like the Marda Permaculture Project, despite pressure from the Israeli government.

“This is where we became a permaculture army that doesn’t have boundaries,” said Bates. “We’re not fighting for a nation, we’re fighting for a planet.”

The afternoon brought some graphic demonstrations of permaculture principles by Maria Ros, an amazing woman in her own right, who left a successful career as a professional dancer and university instructor to learn and teach permaculture and build an ecovillage in Quintana Roo.

IMG_2184

Maria and Hector Reyes gave a session on designing for catastrophe, a subject they know well, living as they do in the hurricane zone of the Yucatan. Hurricane Wilma destroyed much of the work she had done on her permaculture farm for the past four years.
IMG_2171

She remembers her house shuddering in the howling winds, fearing for her walls and roof as she looked out a window at the thatch-roofed Maya house next door. The palm fronds lifted and fell with the winds, emerging unscathed.

The experience was a traumatic one, but she learned an important lesson: The more we observe nature, and the more we incorporate those observations into our designs, the more sustainable our designs will be.
“The Maya design their homes with thatched roofs, so they are not only strong but they let the wild energy move through instead of blocking it,” she said. “In my house, the walls were crying against the wind.”

Bates chimed in with a dramatic illustration of the concept that I will always take with me.
He drew two circles on the chalkboard – one the size of a quarter, and several feet across.

“This is the earthquake in Haiti,” he said, “and this is the earthquake in Chile.”

Then he drew a corresponding quarter-sized circle inside Chile and a large circle around Haiti, representing the number of people who had died in each quake – slightly over 100 in the case of Chile, and thousands in the case of Haiti.

“That’s the result of design,” he said emphatically.

More on this concept can be found on his blog, The Great Change, which is well worth the read.

The day passed with many more lessons, and this was just the beginning. Tomorrow, we’ll get a look at Maya Mountain Research Farm, with a tour by founder Christopher Nesbitt, who bought it from a cattle rancher in 1988 and converted it from a depleted, eroded and relatively unproductive tract to a richly diverse forest.

Here’s a quick glimpse into my first amazing day at Maya Mountain. Stay tuned for the farm tour tomorrow, what Bates refers to as “one of the best examples I’ve seen of permaculture in action.”

At home with the Subcoyote

At home with the Subcoyote

Outside in the darkness, up in the hills not far from here, a chorus of coyotes is greeting the coming of the dawn. How appropriate, I think with a smile. Here in Huehuecoyotl, place of the old, old coyote, I’ve just bid farewell to the greatest coyote of all, Subcoyote Alberto Ruz Buenfil, who is letting me use his home as a base for a few days. Now it’s his time to head into Mexico City, where he is taking the lessons of the Rainbow Caravan for Peace into the barrios of that other place of coyotes, Coyoacán.

I’ve come to Huehuecoyotl to meet his family and some of the people who form this core group of world-changers. I’ve come to break bread, share stories, and glean advice for the journey ahead. Alberto has been in a whirlwind of activity since I arrived – he’s playing a lead role in a film about Fellini’s spiritual journey through Mexico, and the ghost-spirit of the great Italian filmmaker was just here to supervise from another dimension the shooting of some scenes; longtime friend Jose Arguelles, author and visionary, just spent some time here. During my two days here he’s just finished another book and sent it out to the reviewers, underwent a root canal and many hours of community meetings and obligations, and bid farewell to his daughter who is on her way back to Spain; now he’s preparing for a thousand-drum salute and fundraiser for the people of Haiti and a visit from Bolivian President Evo Morales, but still he took time to show me around, orient me to the solar shower and the composting toilet, share photos and reminisce about the incredible 13-year nomadic ecovillage whose trail I now follow, from Mexico to Patagonia.

***

An old legend tells of a time when the Earth is in crisis, and life itself is in danger. In these times, the legend goes, a new type of warrior will arise: a tribe of all races, creeds and nationalities who will be known by the universal symbol of the rainbow, and driven by love, their mission will be to save the planet from extinction.

So writes Alberto in his book, “Los Guerreros del Arcoiris.” (Rainbow Nation Without Borders-Bear & Company publishers)-Alberto has dedicated his life to nurturing this tribe, leading the Rainbow Caravan of Peace on an epic journey through Mexico, Central and South America. This nomadic ecovillage traveled from country to country, led by Alberto’s old schoolbus, La Mazorca, colorfully painted to resemble the iconic ear of corn. The ever-changing tribe sought to connect groups active in resistance to the destructive corporate model. They set up camp in jungles and mountains, in indigenous villages and urban ghettos, sharing music, theater and seeds of practical eco-wisdom: green building techniques, simple alternative technologies, natural healing techniques and more. At the same time, they gathered up bits of local lore and wisdom and connected the disparate groups into a hemispheric network. In August of 2009, the tribe finally disbanded, each dispersing to different parts of the continent to continue the consuming work of social change.

Alberto returned to Huehuecoyotl, the picturesque ecovillage established in 1982 in the mountains near Tepoztlan by Alberto and his community of rainbow warriors. He is letting me use his home as a base for a few days as I organize myself for the next phase of my journey. The beautiful adobe-brick home is filled with light from the arching windows that look out upon the grassy valley below; out the front door, past a tall green row of fragrant hoja santa plants, limestone cliffs tower protectively beyond the beautiful home of his son Odin, a musician and one of Mexico’s leading permaculture practitioners.

I will see Alberto once again before I go, when he hosts Bolivian President Evo Morales for a brief visit to the city on Sunday. Meanwhile, here is a short interview I did with him recently, at his office in the Casa de Cultura Reyes Heroles in Coyoacán. His warning comes as a coyote howl in the fading moonlight.

“Like the Mayan Zapatistas said, we have had a long time to dream. Now is the time to wake up. Because any dream we don’t manifest becomes a nightmare, made by somebody else.”

Guadalajara Guerreros: Fighting for a better world

Guadalajara Guerreros: Fighting for a better world

Today I awoke in the verdant mountains near Tepoztlán in Central Mexico, far from the commotion of city life in Guadalajara. Before I move on, I want to take a few moments to acknowledge the work of 24 extremely dedicated, talented and creative people I met during my time in that city, people who touched my life and gave me hope for a better future.

To read about them, please visit Guerreros de Guadalajara, a bilingual entry in my Flickr account.

Hope prevails through a bitter winter in Bancos de San Hipólito

Hope prevails through a bitter winter in Bancos de San Hipólito

We arrived in the fog-draped settlement of Buenos Aires, Durango, just after 9 a.m. It had been a hard night’s drive through a pouring rain, enlivened only by the stories of my tireless travel companion, human rights lawyer Carlos Chávez of the Jalisco Association in Support of Indigenous People (AJAGI, by its Spanish acronym).

We still had nearly three hours to go before we reached Bancos, but meanwhile, a group of comuneros from Buenos Aires awaited a ride in the back of his pickup truck. Chávez jumped out from behind the wheel he’d manned since 10 p.m. the night before, greeting a shivering cluster of men with good cheer and a round of hearty handshakes. A breakfast invitation followed, and Nora, Cristian and Yaser, three other AJAGI members, joined us as we were led through what looked like a refugee camp. Nora and Cristian had passed the night in the back of the truck; Yaser was less fortunate, having passed the stormy night in Buenos Aires.

A bitter windstorm had ripped through the village, stripping the tin roofs from many of the mud-brick homes in the middle of the night as the residents slept. The unrelenting rains and near-freezing temperatures compounded the misery as residents tried to piece their lives back together.

Nonetheless, a visit from Carlos Chávez and the folks from AJAGI was more than reason enough for a gathering. One family with a sheltered outdoor kitchen still in good working order invited us to huddle together underneath as the rains began again, and steaming freshly ground tortillas came off the grill one by one to envelop home-grown scrambled eggs and savory pork-seasoned beans and potatoes. Family members clustered around to beam at us and urge us to eat more as we wolfed down what was likely their sole daily portion. But to decline would have been an insult, so we obliged.

The strange winds, the unseasonable rains, and the unthinkable snowstorm of two weeks prior were recurring themes in our visit. The summer rains didn’t come in time to water the harvest, and much of the corn crop dried on the stalk. Of what survived, much succumbed to fungus when the rains arrived late. And then, month upon month of winter rains – and now the tornado-like windstorm that has just descended upon them, the likes of which they’ve never seen.

Climate change is not a theory for the Wixaritari, the tribal people named Huichol by the Spaniards for easier pronunciation. They are convinced that they are living it every day, and they are seeing it in shorter growing seasons and strange weather patterns. They don’t know the reasons, but it worries them.

There’s no time to dwell on it, however. There’s firewood to be gathered, roofs to fix, children to feed – and, for some, a regional assembly to attend down in the valley in Bancos.

Attorney Santos De La Cruz Carillo, community members Nazario Navarrete Lara and Fabian Carillo Aguilar, technical advisors Yaser Ventura and Cristian Chávez, and community members Don Jesús Ramírez and Prudencio Ramírez Navarrete, left to right - and still enough room for me.

Spirits were high as we clambered into the back of Chávez’ well-worn and mud-caked Toyota pickup truck. Bancos is in a sheltered valley, and considerably warmer than Buenos Aires, up in the mountaintops some 7,000 feet above sea level. Also, most of these families originally lived in Bancos. The residents of Buenos Aires are modern-day pioneers engaged in the act of resettling and at the same time reforesting the land ravaged by timber poachers from the neighboring mestizo communities.

The resettlement is all a part of a larger strategy, devised by Huichol community leaders hand-in-hand with Carlos and the rest of the AJAGI team, which has provided legal and technical assistance for nearly two decades, helping the community reclaim 55,000 hectares of land that had been annexed away from their territory and encroached upon over the years. An estimated 140,000 hectares are at stake, including a 10,720-hectare swath separating Bancos from its core community of San Andres Cohamiata in the neighboring state of Jalisco. In a groundbreaking decision in 1998, the International Labor Organization ruled that the Huichol people had a right to the land based on ancestral ownership, even though they don’t hold legal titles – a ruling the Mexican government has thus far failed to acknowledge. Repeated pronouncements from the international agency received no response until last year, when the Mexican government finally ruled in Bancos’ favor – but with a catch. It failed to recognize the ancestral rights outlined in a key document called Convention 169, and so the case remains in litigation.

“The case of Bancos at one point was once described by the Special Rapporteur on Indigenous Issues for the United Nations as probably the most important case in the world” with respect to indigenous land rights, said Chávez. “If the case is resolved in the community’s favor, it will be of benefit to all indigenous people in the world.”

In fact, if AJAGI and the Huicholes of Bancos win their case, it will be the first time that an ILO ruling has superseded a federal law, and will set an international precedent for all indigenous peoples.

But this is only one of many strategies, one layer of the many layers of stories to be told about the Wixaritari people. I was fortunate to hear many of them in the past week, and I will be sharing them as time permits. Meanwhile, here are some images from the enormously resilient little community of Bancos.

The Organi-K whirlwind

The Organi-K whirlwind

By Tracy L. Barnett
Yesterday I met with some of the most influential leaders of Mexico City’s environmental movement. Between all the cell phone calls and agenda-checking and detail management, Organi-K founder Arnold Ricalde de Jager shared a few insights in an interview I’ll post a little later. I also got a little window into the whirlwind that is Organi-K.

On the agenda: an alternative forum for the upcoming COP16 talks, to be held in December right here in Mexico City; Pepenafest, a festival to celebrate creative uses of garbage, scheduled for the spring; regrouping for a referendum among the residents at Lomas de Platero, the Ecobarrio project the group is helping to organize;a reforestation project; a ban on plastic bags; a new edition of their seminal book, EcoHabitat; green roofs and recycling, animal rights, the list goes on and on.

But right now, between meetings and phone calls, Arnold has been asked to give a few moments to a wandering journalist, and his attention focuses on the big picture. Ricalde, a founder of the Mexican Green Party, broke ranks with the party when it veered to the right, has served as a city counselor and an advisor to Mayor Marcelo Ebrard, an author and a teacher of sustainability principles, but above all a charismatic organizer, capable of inspiring and mobilizing the masses over the long haul. He flashes a megawatt smile worthy of a Brad Pitt and launches into an impassioned analysis, barely stopping to take a breath.

Mexico City’s growing emphasis on sustainable principles, promoted by Ebrard but carried out by environmental departments in every city agency and ratified by a cooperative legislative assembly, has been driven by necessity, Ricalde says – by the arrival of peak oil, by the dwindling water supplies, by an increase in prices. “It’s not that we woke up one day and it occurred to us to become environmentalists.”

“We had to do it, of necessity,” he said. “20 years ago, we were the most contaminated city on the planet, and we paid the price with our economy, with our health, with our citizenry, and now that we’re running out of oil in this country, we see that the costs of public transport are increasing, and we’re seeing the prices of consumer items increasing, too. We have to make the transition to sustainability; we have no other option.”

Organi-K works to push legislation, like a ban on plastic bags that went through last year, with companies given a year to comply. But more important, Ricalde says, is the change going on at the personal leve.

“After getting various environmental laws passed, trying to move the issue at the governmental level, we realize that this is important, but the most important is the change in each person, in his or her consumption habits; in how one transports oneself, in how they manage their waste, if they separate and recycle, if they make compost – everyone can make compost in their own home.

“Over the years, we’ve learned that ecological change begins within oneself, what we can do in our relationship with the environment. From how we transport ourselves – how I move throughout the day, how much trash I generate, am I consuming organic products or no, do I go by bicycle or by Metro, for example…”

There was much more, and I’ll come back to this with a translation of the interview, but now I have to prepare to meet with the grandfather of the Latin American environmental movement, “Subcoyote” Alberto Ruz, founder of the Rainbow Caravan for Peace.

First I want to mention briefly the others at the meeting, because I’ll be coming back to them, as well: Noelle Romero, a tireless organizer of the Green Circle project and many other initiatives, and Laura Kuri, founder of the bioregional movement in Mexico. I’ll be meeting Noelle on Friday to learn more about green roofs, and I’ll be visiting with Laura at her ecocenter in Cuernavaca later in the month.

Now, for a visit with the Subcoyote…. hasta mañana, amigos.

From Mexico to Palestine: Carbon offsets

From Mexico to Palestine: Carbon offsets

By Tracy L. Barnett
treeMuch has been written about the pros and cons of carbon offsets. The idea, if you haven’t been following, is that you pay money to a nonprofit organization to plant trees or invest in renewables or otherwise reduce the amount of carbon in the atmosphere in an attempt to offset the carbon you’ve generated.

There are many calculators online that help you to figure out how much carbon you’ve generated and where you should donate it. Carbon Footprint is a nice flexible one that lets you calculate individual aspects of your life as opposed to doing a whole audit – both can be good, but since I’m on the road, my lifestyle doesn’t easily fit into many of these calculators. Since my main impact is travel, I figured my mileage and multiplied the air travel by 1.9 to account for the increased impact airplane emissions have (the amount used by Carbon Footprint). It then lets you select from a variety of worthy projects from Kenya to Central America.

Critics compare this system with the Catholic Church’s system of indulgences in Medieval times – a system that allowed people to “buy” forgiveness for their sins by making donations to the Church. They argue that there’s a wide variance among carbon offsetting groups, none of them are regulated and there’s no way to know for sure that the trees you’re paying to plant wouldn’t be planted anyway.

Now I’m not interested in buying forgiveness or its modern manifestation, greenwashing; and I don’t really care if the amount of carbon I’m generating is translated precisely into the right number of trees. I am, however, interested in minimizing my impact while promoting social change. So when I learned that The Farm in Tennessee had set up a system allowing donations to be used to plant trees at the Marda Permaculture Farm, I decided to go that route. I trust the judgment of the folks at The Farm, which has been a leader in promoting sustainable living around the globe for decades; and I also know quite a bit about the Marda project.

Although I don’t know them directly, I have a personal relationship the Marda Permaculture Farm because my sister Tami Brunk is a co-founder. She worked with founder Murad Alkufash to establish the organization, eventually traveling to Marda, a palestinian town located at the West Bank of the Jordan river. She has shared with me much about the group’s work over the years, not just in terms of supplying much-needed food security but in building resilience and hope in the Palestinian territories, where those elusive qualities are so desperately needed.

So, having decided on where I wanted to put my money, I did my own calculations with the help of The Farm’s Trees for Airmiles page and
Geobyte’s City Distance Tool to calculate my mileage: Flying from St. Louis to Mexico City via Dallas racked up 1,481 miles; multiply that by 1.9 as Carbon Footprint suggests and you get 2,813 miles. Then I did a rough calculation of what I think the next two months will look like: Mexico City to Guadalajara to Nayarit to Guadalajara to Mexico City, then down to Cuernavaca, Guerrero, Oaxaca, Chiapas and Quintana Roo before heading over into Belize. All of that comes, very roughly, to about 2,793 miles.

Put it all together, and that comes to about 5,606 miles for the two months or so that I’ll need for Mexico. Using The Farm’s calculation of 1 tree per 5,000 for plane travel, and 1 tree per 1,100 miles for car travel (though I’ll mostly be traveling by bus, which should have a considerably lower impact), and I figured I’m more than covered at $10 a month, which will plant 30 trees this year.

I don’t know if it’s enough or too much. But at least I’m trying – and so are the folks in Marda. As I see it, that can only be a good thing.

James Hansen embodies “never-give-up fighting spirit”

James Hansen embodies “never-give-up fighting spirit”

By Tracy L. Barnett
The man who’s been called the Paul Revere of climate change, Dr. James Hansen, launched his new book, “Storms of My Grandchildren,” last night at Houston’s Wortham Center to a packed house.

James Hansen

Why would Houston be chosen for this event, you might ask? It’s the No. 1 carbon-emitting city in the nation. Progressive Forum Founder Randall Morton pondered this question out loud as he prepared to introduce the imminent climatologist, and his 13-year-old daughter Eva piped up with a pithy response: “Because we need it more.”

Hansen first emerged into the public eye in 1988, when his Congressional testimonies first put the issue of global climate change into public circulation. For awhile he went back to the laboratory and focused on doing science, as he explains it, hoping that other more eloquent spokespeople would take the ball and run with it. Now that the planet is dangerously close to a point of no return, however, he says, his concern for the future of his young grandchildren has spurred him back into the political arena. He’s been arrested at a protest against mountaintop removal in West Virginia and joined protests in Washington, D.C., England and New York, among others. His militancy has made him a lightning rod for climate change deniers.

As a crusading young environmental journalist in 1988, I was captivated by Hansen’s emergence on the political scene. Already a high-profile climatologist with the NASA Goddard Institute. Hansen’s testimonies before Congress that year and the next outlined an unimaginably grim future if we didn’t join forces to reduce the greenhouse gases we were spewing into the atmosphere.

It seemed to me at the time, young idealist that I was, that Dr. Hansen’s stature and his clear evidence would finally bring our leaders to their senses, and that we would begin to steer our nation’s course in the direction of greater sustainability.

Of course, two decades later, things have only gotten worse. In that 20 years, the Arctic ice has begun to melt; droughts, wildfires, storms and floods have become more frequent and more severe; coral reefs have begun to die as the oceans have acidified. People living in low-lying areas like the Maldives and Bangladesh are already seeing the ocean lapping at their doorsteps. The glaciers that feed the rivers that provide drinking water to billions of people are rapidly melting. Inuits in Alaska and Canada are seeing their villages eroded away as the permafrost melts. The vast body of scientific evidence now available confirms the human genesis of this unfolding crisis, despite the so-called “climate gate” that erupted last week over some leaked e-mails from the Anglia Climate Center in England.

And yet Americans list climate change at the very bottom of their list of priorities – far below the ranking of other nations, particularly those who are on the front lines.

Storms of my Grandchildren

I asked Hansen last night why he thought Americans remain so unconcerned. One reason, he said, was La Nina. This cyclical climate pattern led to an unseasonably chilly summer in the Midwest this year. Despite that, the summer of 2009 was the second hottest on record, he said. The problem is that Americans aren’t seeing it because it’s not happening here.

“It’s hard for the public to recognize that we’re in an emergency,” he said. “What they don’t see is that there’s more in the pipeline; the ocean is 4 kilometers deep on average, and it hasn’t yet responded fully to the changes we’ve caused.”

Hansen’s talk, scheduled to coincide with the opening of the United Nations Climate Change Conference in Copenhagen, was an inconvenient truth taken to the next level.

“We are closer to the tipping point than we had realized,” he warned, referring to a series of feedbacks that could be unleashed by the melting of the Arctic ice shelves, combined with other factors to produce runaway climate change.

Unfortunately, he said, the actions that global leaders are planning to announce in Copenhagen “will have no significant effect on business as usual… Politicians are saying the right words, but their actions don’t follow suit.

Hansen’s assessment of the most likely scenario being floated for carbon regulation, cap and trade, was that it’s akin to the Catholic Church’s selling of indulgences in the Middle Ages, in which sinners could buy forgiveness for their sins.

The idea under cap and trade, he said, is that “you don’t really have to reduce your emissions; you can just preserve a forest in Brazil.”

The problem with that, Hansen said, is that demand for wood doesn’t go away, and so a different forest will be felled to provide the wood.

Hansen’s critique of cap and trade is a controversial one, even among progressives. Yesterday’s New York Times put the debate into sharp relief, with Hansen’s Cap and Fade calling for a carbon tax and citizen dividend, and economist Paul Krugman, normally a fan, delivering Unhelpful Hansen.

Regardless of how it’s done, Hansen makes a compelling case that coal should be left in the ground as we begin to power down from an era of cheap fossil fuels.

Asked how he keeps his hope alive after 20 years on the climate trail, Hansen says he’s inspired by his grandchildren. He told a story about his 4-year-old grandson, whom he queried about his persistent failed attempts to deliver a basketball into a hoop.

“You have to have a never-give-up fighting spirit,” the boy told his grandfather.

“Thank goodness he has that spirit,” Hansen reflected with a wry smile. “He’s going to need it.”
