Science Guy Bill Nye’s new book on climate change, Unstoppable, is an outstanding and (I’m fairly certain) unique book about climate change, focusing on the science behind the many solutions available to us. With a friendly, down-to-earth, entertaining delivery, Nye provides clear and useful explanations of both current and just-over-the-horizon technologies and related scientfic phenomena. The result is a book that will appeal both to science enthusiasts and to anyone interested in a constructive, hopeful, extremely well-informed book about the science of fighting climate change.
Nye for the most part takes no sides except that of the science, so that when discussing controversial topics (like nuclear energy, for instance), he provides not a prebaked opinion, but rather a careful description of pros, cons, and unintended consequences. Because he focuses on the scientific realities and near-term possibilities, his perspective is as refreshing as it is informative.
Some of the solutions Nye describes are available right now, like home energy efficiency improvements and solar power generation. Others should emerge in the next few years, like self-driving cars and widespread use of home power battery packs, which still others are only hopes for the future, like entirely new kinds of power transmission lines made from carbon fiber and truly sustainable biofuels.
One shortcoming I see in the book is an incomplete treatment of carbon footprints–although to be fair, few sources I’ve seen take an in-depth approach in calculating carbon footprints (Mike Berners-Lee’s How Bad Are Bananas? is a stand-out exception). For example, Nye more than once refers to nuclear power as carbon-free, which may be true if all you’re looking at is direct emissions from the power plant itself, but which fails to take into account the carbon footprint from construction of these extremely resource-intensive facilities or of mining their fuel (and later handling the resulting nuclear waste). As another example, when discussing self-driving taxipods, Nye doesn’t examine the extra impact of these vehicles having to drive to where their are passengers in the first place, which is probably a negligible concern in urban areas but much more significant elsewhere.
Another problem with the book is Nye’s multi-chapter discussion toward the end of the book about space exploration, a section has virtually nothing to do with climate change. Nye being the C.E.O. of the Planetary Exploration Society, I can well understand his support, but rocket launches (which are required even for, to give an example, the solar-powered spacecraft he discusses) are among the very worst offenders in terms of greenhouse gas emissions of any human activity. Climate impact expert Mike Berners-Lee estimates a space shuttle launch emits at least 4,600,000 kilograms CO2 equivalent, roughly similar to 200 years of emissions for an average American, 1,500 years of emissions for an average citizen of China, or 46,000 years of emissions for the average Malawian.
Space boosterism emphatically doesn’t belong in a book on climate change, but you can safely skip chapters 31 to 33 without missing anything important climate change information, or read them if you are curious about space travel (though I’d encourage everyone to think of that as something to explore further after we’ve dealt with climate change). Either way, those chapters don’t much detract from what otherwise, on the whole, is an excellent set of insights into climate change and its solutions.

Once there was an adorable little chipmunk named Fluffy William, who for whatever reason could understand English. It was just one of those things.
Fluffy William was so wee and cute that he charmed everyone he met, except for gardeners, from whose strawberry patches he had a habit of selecting a strawberry, eating just one bite, and then moving on–though in Fluffy William’s defense, his wee stomach was so small that one bite of strawberry filled him right up.
Fluffy William lived an unusually happy chimpmunk life, with cool leaves to rustle under in hot weather and a warm nest to bed down in when it turned cold, until he chanced to be sitting by an open window during a ninety-minute documentary on climate change. Climate change, it turned out, was weather and temperatures and reliable natural cycles all going haywire. Climate change was floods in the Spring and droughts in the Summer and hurricanes in the Fall and God only knows what kind of trouble in the winter. Climate change would make it harder for people to grow food, which would make for more desperate people, which would make for more disasters and refugees and wars. It rapidly became clear to Fluffy William, understanding English as he did, that somebody needed to do something about this climate change problem, and quick.
So Fluffy William ventured deep into the woods until he came to the burrow of Elder Stern Wanda, the wisest and most respected chipmunk anywhere thereabouts. There, breathlessly, he explained about climate change.
“We have to do something about this terrible problem, Elder Stern Wanda!” cried Fluffy William. “But what can I do? I’m just one little chipmunk.”
“You can’t do anything,” said Elder Stern Wanda. “Anything you might try to do would be totally useless. It’s the humans who have to do something about it, and everybody knows you can’t make a human do something they haven’t chosen to do on their own without a gun or a fistful of money.” Elder Stern Wanda picked up an old, chewed-up acorn and gnawed at it gingerly with her one remaining front tooth. The effort seemed to exhaust her after a few gnaws, and she put it back down. Age has its compensations, but it’s still a pain in the neck.
“So humans have to each decide to change their habits on their own?” said Fluffy William.
“Don’t hold your breath for it,” said Elder Stern Wanda. “Now scamper along home.”
So Fluffy William scampered along home and did nothing. That next spring there was a terrible flood, and in the summer there was a terrible drought. Regrettably, Fluffy William could not compete with the other chipmunks for the scarce food available, as he was so wee and cute, so he died of starvation.
He never did find out whether the humans did anything about climate change.
I’ve been working on my current book project, the novel The Town at World’s End, since late 2012. The story follows climate change educator Jess Finch from tragedy in an unseasonable and outsize storm through trying to piece her life back together and make a real difference in climate change. On the way, it imparts a huge amount of specific, practical information on reducing carbon footprint–not just facts, but experiences, problems, contradictions, motivation, obstacles, side benefits … even how to make sure the wires don’t fall into the wall when you’re installing a programmable thermostat.
Anyway, it wasn’t until a good ways into the project that I realized I needed to be maintaining a bibliography. Even though this is a novel, it’s based on a massive body of research, writing, and other resources, many of which are well worth reading (or seeing, as the case may be).
How long ’til doomsday? Should I replace my windows? How do I grow my own food year round in a cold climate without wasting energy? What’s biochar? How do I talk with someone who doesn’t even believe climate change is a threat? It’s all in the below, plus a lot more. Actually, it’s enormously encouraging to me to realize how many smart, dedicated, hard-working, resourceful people are out there working on all of the facets of the climate change problem. If you’re one of them, I’d like to take this moment to express my deep gratitude and to cheer you on.
I still have a lot of work to do in pulling that bibliography together, adding other items, formatting it usefully, categorizing, and so forth, but as an initial step I thought I’d share the initial bibliography notes, in case it’s helpful to anyone in finding good sources of information on climate change and carbon footprint.

One of the most demoralizing things about climate change is that it’s generally a one-way process: it’s easy for us to put more greenhouse gases into the atmosphere, but not so much for us to take them back out–at least, that’s what I thought until recently.
True, there has been some research into carbon sequestration (putting carbon dioxide directly into underground spaces or at the bottom of the sea), but these processes aren’t very far advanced or very affordable, and some of the plan for them is just to capture CO2 being produced by fossil fuel plants and sequester that. The fossil fuel industry likes to hold this very theoretical idea out as though it’s an available technology, so as to get a free pass to burn more fossil fuels.
But I mentioned that there was some hope, and there is: biochar.
What is biochar? It’s basically charcoal, an extremely carbon-rich material made at high temperatures, from 200 to 700 degrees Fahrenheit, which consumes pretty much everything in the fuel except the carbon. Biochar can be made from practically any burnable material–wood, seed pods, husks, brush, paper, manure, etc.–even trash.
What’s so great about that? A few things, actually! First, using the right process to make it, biochar produces energy without producing much in the way of greenhouse gas emissions. Second, the process that makes biochar can alternatively make liquid fuels from renewable sources. Third, and most intriguingly, biochar is very stable: you can bury it in the ground, and the carbon won’t go anywhere for hundreds to thousands of years. Fourth, when you do bury it in the ground, it increases the fertility of the soil by making necessary chemicals more available to plants and by helping retain and regulate water in the soil. Fifth, the process is simple enough that it can be used for everything from massive plants to cookstoves.
So the cycle can go something like this: plants grow, absorbing and using carbon from the atmosphere. The plants are harvested, and some or all of the resulting plant matter is made into biochar, producing up to about six times as much energy as it consumes in the process. The biochar is then buried in the ground, accelerating plant growth. Even without this acceleration, the new plants that grow where the old ones were harvested absorb more carbon from the atmosphere, and the process continues.
If we’re willing to commission a lot of large biochar plants and to make biochar a standard part of preparing agricultural lands–including reclaiming currently unproductive lands, such as former farmland that is tapped out or turning to desert–then we can actually pull a huge amount of the carbon dioxide we’ve generated over the past couple of centuries back out of the atmosphere, and reverse the process we’ve been causing that is currently wrecking our climate with no relief in sight.
Thanksgiving, Christmas, Passover, the Fourth of July, and other holidays all have a few things in common: they tend to involve travel and special meals or feasts. For many extended families, like mine, these kinds of occasions are the only times during the year we all have a chance to see each other, yet travel and food are two of the four biggest ways individuals and households contribute to global warming*. So our choices are to give up on sustainability over the holidays, to give up on the holidays, or to find ways to the holidays more sustainable, starting now. These posts are focused on that last option.
The way I propose we look at cutting any emissions is “biggest impacts first.” We often look for the easiest, most obvious ways to act more sustainably, but the truth is that there are so many low-impact things we can do, we can easily spend all our time on those and never get to the good stuff, the major savings. That’s where the Big Four offer a starting point. With those in mind, here are some tips for the making the largest possible savings in emissions at the holidays.
Rethink air travel: Flying around the country and even the rest of the plant has become relatively inexpensive and easy, but unfortunately it’s one of the worst offenders in terms of emissions. Not only do planes burn a lot of fossil fuels, they push out their exhaust at altitudes where their bad effects are at least doubled compared to what they would be on the ground. It’s not up to me to tell you or your family members not to fly, but there are ways to fly less, for instance driving together in an efficient car, taking a bus or plane or boat, or making one longer visit instead of two shorter ones. For more information on flying, see “You Want Me to Stop Doing What?”
If the trip is very important to you and you can’t find any way to make it other than air travel, you can consider making a donation to offset the climate impact. For example, Cool Earth is a non-profit organization that does excellent work preserving forests, which is one of the best possible ways to help slow climate change (even better than planting new trees). Donations to organizations that make a smaller or less direct impact would have to be proportionately larger.
The cost of offsetting a flight depends very much on how long the flight is. For a transatlantic round trip, an offset donation to an organization like Cool Earth would be only $20.90. A short round trip, for instance between Niagara Falls and New York City, would be only about $2.50. (Source: How Bad Are Bananas by Mike Berners-Lee)
Not making the trip in the first place is certainly the ideal way to go, but offsetting is a decent alternative if you are having trouble finding away around flying.
Use food well: According to FeedingAmerica.org, between 25% and 40% of all food produced in the U.S. will never be eaten. Take a moment to reflect on that with me: At least a quarter of all our food, and possibly closer to half, goes completely to waste! Meanwhile, much of this food is produced with energy-intensive methods that burn many tons of fossil fuels; methane from ruminant livestock (cows, sheep, and goats) that is more than 20 times as potent in damaging the climate than carbon dioxide; and chemical fertilizers that release Nitrous Oxide (NO2), a greenhouse gas more than 300 times as potent as carbon dioxide. Careful attention to what and how much food we buy and how we serve and store it can cut our personal food waste to far below the usual amount.
Time permitting, I’ll be posting further ways to transform the holidays over the coming weeks. A happy and sustainable holiday season to all!

In his deeply researched and surprising book Don’t Even Think About It: Why Our Brains Are Wired to Ignore Climate Change, author George Marshall helps us understand the true nature of climate change and why it’s so hard for us to act on something that threatens to destroy us.
His points are surprising and force us to reframe our entire understanding of the issue. Here are a few examples, many of which don’t make sense until you get the benefit of Marshall’s full explanation:
I had some anxiety as I read this book, not so much because it’s about climate change, but because for the first 40 chapters or so, Marshall tells us only how NOT to communicate about climate change: why politically loaded messages hurt the cause, how making the problem scarier encourages us to ignore it even more, and how the science isn’t going to convince much of anyone, for instance. I was afraid that I was going to get to the end of the book and find out that his conclusion was “So basically, we’re f***ed.”
Thankfully, it wasn’t. At the end of the book, Marshall revisits all his key points and turns them on their heads, showing how the things we’re doing wrong in communicating climate change can maybe be done differently and effectively. It’s not that those of us who are working to solve the climate change problem aren’t trying hard enough to communicate: it’s that there’s an entirely different and unexpected way for us to go about it that is likely, based on a great deal of research and investigation, to do a much, much better job.
We tend to understand climate change in limited ways, each of us confined to some extent by our peers and expectations. Marshall’s book helps us break out of those limited understandings to see the big picture, and in the process to find new resolve, new allies, and new hope for immediate change.
George Marshall has devoted his career to one perplexing question. As he puts it, “Why, when the evidence is so strong, and so many agree that this is our greatest problem, are we doing so little about climate change?” What he has discovered over time is that we’re practically built to ignore problems like climate change. He also has developed an understanding of dialog with people who don’t believe climate change is happening, or don’t believe that it’s humans who are causing it, that uncovers a much, much more effective way for we who are fighting climate change to engage in discussion with people who aren’t. Below is the quick summary, but if you want to know more, go to the source, where many other resources are available: http://www.climateaccess.org/resource/tip-sheet-george-marshall-how-talk-climate-change-dissenter .
I had been reading some climate change materials on Quora recently, and in with some great information, there was someone who had asked whether people are overly concerned with their personal carbon footprints. There had been only one response so far, and it was from someone who said, essentially “Yes, they are: an individual person’s contribution to climate change is a drop in the ocean.” This may have been a troll, admittedly, because late in his post he says “… it is not rational to worry about one’s personal footprint. A far more reasonable and productive approach would be to worry about other people’s.” Is it just me, or is the error there really easy to spot? So I’d like to suggest a way of looking at this question that I think might make the answer clear. I think that we can agree that governments, businesses, and other people could at least in theory make a lot more difference in climate change than any one of us can individually.
Democractic governments are only successful in pursuing policies that their constitutents support. If you and I and all the other voters aren’t minding our own carbon footprints, we’re giving our governments a clear message that lowering carbon footprint isn’t important. Virtue generally does not originate with politicians, unfortunately, and when it does, it is often voted out of office unless it has a lot of supporters out in the populace.
Some businesses, certainly, try to lower their carbon footprints, but you can only do so much of this before it starts costing more money than you get out of it, and most businesses can’t afford to put themselves at a competitive disadvantage in this way. Corporations are actually required by law to pursue profitable approaches, and would run afoul of the law and/or shareholders if they spent too much money being environmentally friendly.
The only way to change businesses is for customers to demand something different. As long as people are happy with buying goods and services that come from businesses with an unnecessarily huge carbon footprint, those goods and services will continue to be offered–and usually more cheaply than sustainable alternatives.
People like you and I, by purchasing in a sustainable way, can contribute to growing sustainable businesses and encourage more businesses to change. Without us voting with our wallets, this change will not happen.
Sure, we’d like everybody else to lower their carbon footprint–but why should they, if we don’t? By doing everything we can to lower our personal contributions to climate change, we can be the trail-blazers. It’s true, no one may follow us–but if we wait for somebody else to lead the way, we’re unlikely to ever get anywhere.
So yes, individual carbon footprints are a somewhat piddling amount of overall greenhouse gas emissions, but without reducing them, none of the larger sources are likely to budge. Lead by example; be the change you want to see in the world.
