Late last week, in the lobby of a particularly unglamorous downtown San Francisco building, a group of passionate but polite activists met with a bureaucrat who stepped forward to hear what they had to say about the fate of the Earth. The activists wanted to save the world. The particular part of it that might be under their control involved getting the San Francisco Retirement Board to divest its half a billion dollars in fossil fuel holdings, one piece of the international divestment movement that arose a year ago.

Sometimes the fate of the Earth boils down to getting one person with modest powers to budge.

The bureaucrat had a hundred reasons why changing course was, well, too much of a change. This public official wanted to operate under ordinary-times rules and the idea that climate change has thrust us into extraordinary times (and that divesting didn’t necessarily entail financial loss or even financial risk) was apparently too much to accept.

The mass media aren’t exactly helping. Last Saturday, for instance, The New York Times gave its story on the International Panel on Climate Change’s six-years-in-the-making report on the catastrophic future that’s already here below-the-fold front-page placement, more or less equal to that given a story on the last episode of Breaking Bad. The end of the second paragraph did include this quote: “In short, it threatens our planet, our only home.” But the headline (“U.N. Climate Panel Endorses Ceiling on Global Emissions”) and the opening paragraph assured you this was dull stuff. Imagine a front page that reported your house was on fire right now, but that some television show was more exciting.

Sometimes I wish media stories were organized in proportion to their impact. Unfortunately, when it comes to climate change, there is not paper enough on this planet to properly scale up a story to the right size. If you gave it the complete front page to suggest its import, you would then have to print the rest of the news at some sort of nanoscale and include an electron microscope for reading ease.

Hold up your hand. It’s so big it can block out the sun, though you know that the sun is so much bigger. Now look at the news: in column inches and airtime, a minor controversy or celebrity may loom bigger than the planet. The problem is that, though websites and print media may give us the news, they seldom give us the scale of the news or a real sense of the proportional importance of one thing compared to another. And proportion, scale, is the main news we need right now — maybe always.

As it happens, we’re not very good at looking at the biggest things. They may be bigger than we can see, or move more slowly than we have the patience to watch for or remember or piece together, or they may cause impacts that are themselves complex and dispersed and stretch into the future. Scandals are easier. They are on a distinctly human scale, the scale of lust, greed, and violence. We like those, we understand them, we get mired in them, and mostly they mean little or nothing in the long run (or often even in the short run).

A resident in a town on the northwest coast of Japan told me that the black 70-foot-high wave of water coming at him on March 11, 2011, was so huge that, at first, he didn’t believe his eyes. It was the great Tohoku tsunami, which killed about 20,000 people. A version of such cognitive dissonance occurred in 1982, when NASA initially rejected measurements of the atmosphere above Antarctica because they indicated such a radical loss of ozone that the computer program just threw out the data.

Some things are so big you don’t see them, or you don’t want to think about them, or you almost can’t think about them. Climate change is one of those things. It’s impossible to see the whole, because it’s everything. It’s not just a seven-story-tall black wave about to engulf your town, it’s a complete system thrashing out of control, so that it threatens to become too hot, too cold, too dry, too wet, too wild, too destructive, too erratic for many plants and animals that depend on reliable annual cycles. It affects the entire surface of the Earth and every living thing, from the highest peaks to the depths of the oceans, from one pole to the other, from the tropics to the tundra, likely for millennia — and it’s not just coming like that wave, it’s already here.

It’s not only bigger than everything else, it’s bigger than everything else put together. But it’s not a sudden event like a massacre or a flood or a fire, even though it includes floods, fires, heat waves, and wild weather. It’s an incremental shift over decades, over centuries. It’s the definition of the big picture itself, the far-too-big picture. Which is why we have so much news about everything else, or so it seems.

To understand climate change, you need to translate figures into impacts, to think about places you’ll never see and times after you’re gone. You need to imagine sea level rise and understand its impact, to see the cause-and-effect relations between coal-fired power plants, fossil-fuel emissions, and the fate of the Earth. You need to model data in fairly sophisticated ways. You need to think like a scientist.

Given the demands of the task and the muddle of the mainstream media, it’s remarkable that so many people get it, and that they do so despite massive, heavily funded petroleum industry propaganda campaigns is maybe a victory, if not enough of one.

Four months ago, two bombers in Boston murdered three people and injured hundreds in a way spectacularly calculated to attract media attention, and the media obeyed with alacrity. Climate change probably fueled the colossal floods around Boulder, Colorado, that killed seven people in mid-September, but amid the copious coverage, it was barely mentioned in the media. Similarly, in Mexico, 115 people died in unprecedented floods in the Acapulco area (no significant mention of climate change), while floods reportedly are halving Pakistan’s economic growth (no significant mention), and 166 bodies were found in the wake of the latest Indian floods (no significant mention).

Climate change is taking hundreds of thousands of lives in Africa every year in complex ways whose causes and effects are difficult to follow. Forest fires, very likely enhanced by climate change, took the lives of 19 firefighters facing Arizona blazes amid record heat waves in July. Again, climate change generally wasn’t the headline on that story.

(For the record, climate change is clearly helping to produce many of the bigger, more destructive, more expensive, more frequent disasters of our time, but it is impossible to point to any one of them and say definitely, this one is climate change. It’s like trying to say which cancers in a contaminated area were caused by the contamination; you can’t, but what you can say is that the overall rise in cancer is connected.)

Not quite a year ago, a climate-change-related hurricane drowned people when superstorm Sandy hit a place that doesn’t usually experience major hurricane impact, let alone storm surges that submerge amusement parks, the New York City subway system, and the Jersey shore. In that disaster, 148 people died directly, nearly that many indirectly, losses far greater than from any terrorist incident in this country other than that great anomaly, 9/11. The weather has now become man-made violence, though no one thinks of it as terrorism, in part because there’s no smoking gun or bomb — unless you have the eyes to see and the data to look at, in which case the smokestacks of coal plants start to look gun-like and the hands of energy company CEOs and well-paid-off legislators begin to morph into those of bombers.

Even the civil war in Syria may be a climate-change war of sorts: over the past several years, the country has been hit by its worst drought in modern times. Climate and Security analyst Francesco Femia says, “Around 75 percent of [Syrian] farmers suffered total crop failure, so they moved into the cities. Farmers in the northeast lost 80 percent of their livestock, so they had to leave and find livelihoods elsewhere. They all moved into urban areas — urban areas that were already experiencing economic insecurity due to an influx of Iraqi and Palestinian refugees. But this massive displacement mostly wasn’t reported. So it wasn’t factoring into various security analyses. People assumed Syria was relatively stable compared to Egypt.”

Column Inches, Glacial Miles

We like to think about morality and sex and the lives of people we’ve gotten to know in some fashion. We know how to do it. It’s on a distinctly human scale. It’s disturbing in a reassuring way. We fret about it and feel secure in doing so. Now, everything’s changed, and our imaginations need to keep pace with that change. What is human scale anyway? These days, after all, we split atoms and tinker with genes and can melt an ice sheet. We were designed to think about human-scale phenomena, and now that very phrase is almost as meaningless as old terms like “glacial,” which used to mean slow-moving and slow to change.

Nowadays glaciers are melting rapidly or disappearing entirely, and some — those in Greenland, for example — have gushing rivers of ice water eating through their base. If the whole vast Greenland ice sheet were to melt, it could raise global sea levels by 23 feet.

We tend to think about climate change as one or two or five things: polar ice, glaciers melting, sea-level rise, heat waves, maybe droughts. Now, however, we need to start adding everything else into the mix: the migration of tropical diseases, the proliferation of insect pests, crop failures and declining crop yields leading to widespread hunger and famine, desertification and flooded zones and water failures leading to mass population shifts, resource wars, and so many other things that have to do with the widest systems of life on Earth, affecting health, the global economy, food systems, water systems, and energy systems.

It is almost impossibly scary and painful to contemplate the radical decline and potential death of the oceans that cover 70 percent of the Earth’s surface and the dramatic decrease of plankton, which do more than any other type of organism to sequester carbon and produce oxygen — a giant forest in microscopic form breathing in what we produce, breathing out what we need, keeping the whole system going. If you want to read something really terrifying, take a look at the rise of the Age of Jellyfish in this review of Lisa-Ann Gershwin’s book Stung!: On Jellyfish Blooms and the Future of the Ocean. Maybe read it even if you don’t.

Only remember that like so much about climate change we used to imagine as a grim future, that future is increasingly here and now. In this case, in the form of millions or maybe billions of tons of jellyfish proliferating globally and devouring plankton, fish eggs, small fish, and bigger creatures in the sea we love, we know, we count on, we feed on, and now even clogging the water-intake pipes of nuclear power plants. In the form of seashells dissolving in acidic waters from the Pacific Northwest to the Antarctic Ocean. In the form of billions of pine-bark beetles massacring the forests of the American West, from Arizona to Alaska, one bite at a time.

It’s huge. I think about it, and I read about it, following blogs at Weather Underground, various climate websites, the emails of environmental groups, the tweets of people at 350.org, and bits and pieces of news on the subject that straggle into the mainstream and alternative media. Then I lose sight of it. I think about everything and anything else; I get caught up in old human-scale news that fits into my frameworks so much more easily. And then I remember, and regain my sense of proportion, or disproportion.

The Great Wall, Brick by Brick

“Here’s the single most important thing you need to know about the IPCC report: It’s not too late. We still have time to do something about climate disruption. …Bottom line: Our house is on fire. Rather than argue about how fast it’s burning, we need to start throwing buckets of water.”

The changes required to address climate change are colossal, but they are made up of increments and steps and stages that are more than possible. Many are already underway, both as positive changes (adaptation of renewable energy, increased energy efficiency, new laws, policies, and principles) and as halts to destruction (for example, all the coal-fired plants that have not been built in recent years and the Tar Sands pipeline that, but for popular resistance, would already be sending its sludge from Alberta to the Gulf of Mexico). The problem is planetary in scale, but there is room to mitigate the worst-case scenarios, and that room is full of activists at work. Much of that work consists of small-scale changes.

As Sierra Club Executive Director Michael Brune put it last week, “Here’s the single most important thing you need to know about the IPCC report: It’s not too late. We still have time to do something about climate disruption. The best estimate from the best science is that we can limit warming from human-caused carbon pollution to less than 3.6 degrees Fahrenheit — if we act now. Bottom line: Our house is on fire. Rather than argue about how fast it’s burning, we need to start throwing buckets of water.”

There are buckets and bucket brigades. For example, the movement to get universities, cities, churches, and other entities to divest their holdings of the top 200 fossil-fuel stocks could have major consequences. If it works, it will be achieved through dedicated groups on this campus or in that city competing in a difficult sport: budging bureaucrats. It’s already succeeded in some key places, from the city of Seattle to the national United Church of Christ, and hundreds of campaigns are underway across the United States and in some other countries.

My heroes are now people who can remain engaged with climate change’s complex and daunting facts and still believe that we have some leeway to determine what happens. They insist on looking directly at the black wall of water, and they focus on what we can do about the peril we face, and then they do it. They do their best to understand scale and science, and their dedication and clarity comes from connecting their hearts to their minds.

I hear people who are either uninformed or who are justifying disengagement say that it’s too late and what we do won’t matter, but it does matter, because a rise in the global temperature of two degrees Celsius is going to be very, very different from, say, five degrees Celsius for almost everything living on Earth now and for millennia to come. And there are still many things that can be done, both to help us adapt to the radical change on the way and to limit the degree of change to which we’ll have to adapt. Because it’s already risen .8 degrees and that’s been a disaster — many, many disasters.

I spent time over the last several months with the stalwarts carrying on a campaign to get San Francisco to divest from its energy stocks. In the beginning, it seemed easy enough. City Supervisor John Avalos introduced a nonbinding resolution to the Board of Supervisors, and to everyone’s surprise it passed unanimously in April on a voice vote. But the board turned out only to have the power to recommend that the San Francisco Retirement Board do the real work of divesting its vast holdings of fossil-fuel stocks. The retirement board was a tougher nut to crack.

Its main job, after all, is to ensure a safe and profitable pension fund and in that sense, energy companies have, in the past, been good investments. To continue on such a path is to be “smart about the market.” The market, in the meantime, is working hard at not imagining the financial impact of climate change.

The failure of major food sources, including fishing stocks and agricultural crops, and the resultant mass hunger and instability — see Syria — is going to impact the market. Retirees in the beautiful Bay Area are going feel it if the global economy crashes, the region fills with climate refugees, the spectacularly productive state agricultural system runs dry or roasts, and the oceans rise on our scenic coasts. It’s a matter of scale. Your investments are not independent of nature, even if fossil-fuel companies remain, for a time, profitable while helping destroying the world as humanity has known it.

Some reliable sources now argue that fossil-fuel stocks are not good investments, that they’re volatile for a number of reasons and due to crash. The IPCC report makes it clear that we need to leave most of the planet’s fossil fuel reserves in the ground in the coming decades, that the choice is either to fry the planet or freeze the assets of the carbon companies. Activists are now doing their best to undermine the value of the big carbon-energy corporations, and governments clued in to the new IPCC report will likely join them in trying to keep the oil, gas, and coal in the ground — the fossil fuel that is also much of the worth of these corporations on paper. If we’re lucky, we’ll make them crash. So divesting can be fiscally sound, and there is a very strong case that it can be done without economic impact. But the crucial thing here isn’t the financial logistics of divestment; it’s the necessity of grasping the scale of things, understanding the colossal nature of the problem and the need to address it, in part, by pressuring one small group or one institution in one place.

To grasp this involves a feat of imagination and, I think, a leap of faith: a kind of conviction about what matters, about living according to principle, about understanding what is too big to be seen with your own eyes, about correlating data on a range of scales. A lot of people I know do it. If we are to pull back from the brink of catastrophe, it will be because of their vision and their faith. You might want to thank them now, and while your words are nice, so are donations. Or you might want to join them.

That there is a widespread divestment movement right now is due to the work of a few people who put forth the plan less than a year ago at 350.org. The president has already mentioned it, and hundreds of colleges are now in the midst of or considering the process of divesting, with cities, churches, and other institutions joining the movement. It takes a peculiar kind of genius to see the monster and to see that it might begin to be pushed back by small actions — by, in fact, actions on a distinctly human scale that could still triumph over the increasingly inhuman scale of our era.

Hold up your hand. It looks puny in relation to the sun, but the other half of the equation of scale is seeing that something as small as that hand, as your own powers, as your own efforts, can matter. The cathedral is made stone by stone, and the book is written word by word.

If there is to be an effort to respond to climate change, it will need to make epic differences in economics, in ecologies, in the largest and most powerful systems around us. Though the goals may be heroic, they will be achieved mostly through an endless accumulation of small gestures.

Those gestures are in your hands, and everyone’s. Or they could be if we learned to see the true scale of things, including how big we can be together.
