We have just finished up work on our updated, improved and expanded 2017 edition of Climate Gamble! One might even call it the definitive edition!
The foreword by the late Sir David MacKay (previously available only on our Paris COP21 special edition of the book, and this website). We owe David so much, both for his own excellent work that also was a big inspiration for us to write this book and for providing the foreword. Our condolences to family and friends.
Key takeaways for each chapter (also available on Paris COP21 edition).
Latest data for the graphs.
Some minor fixes to grammar.
Some extra paragraphs to better elaborate some points we make, based on reader feedback.
A few extra footnotes and citations on our claims.
A discount on the price of both the paperback and Kindle-edition. That’s right, you get more book for less money!
And last but not the least: a proper index to help you use the book more efficiently as a reference! (paperback only)
Our special thanks go to Bruce and Martin for their excellent feedback and support that made this edition, along with a professionally made index, possible.
Some notes: We have pulled the current paperback from Amazon (although it is still available through some sellers), and the new edition should appear in a few days, certainly by the first of April, 2017 (no, this is not an April Fools joke 😉 ). The title has 2017 edition on it, to make it stand out.
EDIT: The new versions are now online and available! Here:
We also updated the new edition on top of the old Kindle edition, so you can get the new version for free (we think, not totally sure how this works but you should be able to update your kindle-book by enabling updates on your Amazon-account).
Finally, thanks for everyone involved in helping out spread the message of evidence based climate policy!
Professor Sir David J C MacKay, famous for his excellent book “Sustainable Energy: Without hot air,” very kindly provided the following foreword for our COP21 edition of Climate Gamble. He passed away on 14th April 2016 and will be much missed by everyone interested in “pro-arithmetic” energy discussion.
Climate change action is remarkably difficult.
Society has many levers available:
demand-reduction through lifestyle change or technology changes;
eating less meat;
carbon capture and storage;
solar radiation management;
Every lever has technical limits and political difficulties. Bioenergy, for example, requires very large land areas, and may have environmental impacts. Eating less meat could make an enormous impact [see globalcalculator.org], but many view vegetarianism as a political non-starter. Some people object to the land area required for wind power and solar power, and the intermittency of wind and solar is a technical challenge.
Making a plan that adds up and that is politically and economically credible is not easy.
Anyone who suggests that one of these levers should not be used by society must recognise that this constraint inevitably makes the task of climate change action harder.
I think that some people view nuclear power as untouchable because the language for describing the dangers of nuclear radiation is too black and white. When we talk about other forms of radiation, everyone understands that there is a scale ranging from harmful to harmless, and we have nuanced language to distinguish between, for example “desert sunshine” and “moonlight”, and other levels of “bright” or “dim” radiation in-between.
Everyone knows that midday desert sun can be harmful if one lies in it without protection. And everyone knows that moonlight is essentially harmless. Yet moonlight is made up of just the same photons as sunshine! The reason why moonlight is harmless is that it is 400,000 times less bright than sunshine.
When people talk about nuclear radiation, our language lacks analogous terms for “bright” and “dim”. Nuclear radiation is just said to be “toxic”, “harmful” or “dangerous”. Black and white. But in fact nuclear radiation can be like sunlight, and it can be like moonlight. There are levels of radiation that are lethal, and levels of radiation that are essentially harmless.
Responsible citizens should not simply rule out nuclear power from the portfolio of climate-change options without properly, quantitatively understanding the true risks.
Yes, the nuclear industry has had accidents. Yes, in some countries, the nuclear industry has had a reprehensible track-record of mis-management and dishonesty. Yes, nuclear waste lasts a long time (as do many environmental pollutants).
Rauli wrote a journal on his 12 days of attending and handing out (3,000!) Climate Gamble books during COP21 with Janne.
The style is somewhat personal, so read at your own risk. Needless to say, it was a highly interesting trip, going from being teargassed by the riot police to meeting Jim Hansen to speaking at what amounted the first ever COP discussion panel on nuclear and climate that went well and without disturbances.
Greetings from Paris! Despite considerable logistical difficulties, we’ve managed to hand out nearly 2000 copies of Climate Gamble to interested people around COP21 climate conference; many thanks to everyone who’ve supported our campaign so far.
As expected, there has been some criticism. Many people sincerely believe nuclear power has unacceptable risks or drawbacks, or that nuclear industry is part of the problem rather than the solution.
This line of reasoning is entirely valid and supported by strong arguments. Nuclear power is far from the problem-free solution it is sometimes portrayed as, and nuclear industry hasn’t been exactly the shining paragon of good corporate citizenship. While there are some bad arguments against nuclear power (CO2 emissions, for example: lifecycle emissions are broadly similar to lifecycle emissions of wind power), there are also good arguments and very smart, sincere people behind the anti-nuclear position.
We obviously disagree with some of the conclusions that are made from the same premises. Our chief disagreement is in whether we need nuclear power or not, and whether the benefits outweigh the risks. We believe it may be possible to power the global society with renewables alone, but we are afraid that without nuclear, we are taking more risks in the climate fight than we should take. This is not an isolated opinion: among others, some very influential climate scientists are saying the exact same things. Furthermore, reviews of non-nuclear climate mitigation scenarios find consistently that they are dependent on a large set of hopes and assumptions becoming reality.
While it is far from certain that we can do the job even with nuclear, the amount of lucky breaks humanity needs is almost certainly smaller if we allow ourselves to use all the options. If we fail to mitigate climate change while denouncing nuclear power, our descendants – if there are any – will forever wonder whether the crisis might have been averted or at least its worst impacts mitigated if nuclear energy had not been opposed so strenuously. We think we owe it to future generations human and nonhuman to at least keep an open mind regarding potential solutions to one of humanity’s greatest challenges so far.
But even more important, in my opinion, is that we allow those who are concerned about our common home to join forces. It seems highly improbable much progress will be made if those concerned about the environment or social justice devote one hand to fighting those who agree with the broad goals, but disagree over some specifics of the strategy. This is one of the key reasons why I’m involved in the fledgling Ecomodernist movement: I want to help provide a platform for those who have felt excluded from traditional environmental activism, because they happen to be in some disagreement with some of the values and premises of the traditional environmentalism.
This year’s Climate March was advertised with the words “if we want to change everything, we need everybody.” There is much truth in these words. If the label “environmental activist,” for example, is reserved for only those who subscribe to the tenets of the traditional movement, it is painfully clear we will fail. In the timeframe we have available at least (less than 35 years), there are simply no prospects whatsoever for “converting” the required majority of world’s population to accept a set of values and premises that are highly Western-centric, Leftist, and make some very strong assumptions about particular technologies for example.
Instead of hoping a mass conversion and adoption of traditional environmental values hook, line and sinker, I believe environmental activists need to reach out to those who’ve been excluded so far. This year, the Ecomodernist movement brought about dozen people to march for climate in Helsinki. Only a dozen, because we organised our participation on a very short notice; but dozens more indicated they would like to participate in the future. With one or two exceptions, not one of them had ever demonstrated for the environment: most hadn’t ever been in a demonstration of any kind.
Perhaps you believe the environmental movement can do without these people. Perhaps you even believe it should do without. If you think so, I think you are wrong. In the aftermath, there were obviously some who questioned why we carried banners supporting low-carbon energy – nuclear power. But the wisest comment came from a self-described opponent of nuclear power: this is a time when we should concentrate on what we have in common, rather than focusing on what separates us.
I heartily agree. These words, among others, have already influenced my thinking. In the past, I’ve been highly critical of traditional environmentalists and sometimes attacked them rather viciously for being “dumb” in their opposition to nuclear power, or in their support for highly destructive practices such as widespread bioenergy use just because it’s nominally “renewable.” I apologise for being such a jerk and try to rein it in, preferably stopping it entirely. We really do need to focus on what we have in common: our concern for our common home and those whose home it is.
It is true, as several critics have pointed out, that many “new” environmentalists have been highly aggressive towards existing environmentalism and environmentalists. I’ve been one of those aggressive people, after all. I think this needs to stop, if we want to change things rather than flaunt ourselves to the small circle of like-minded people. There is no joy nor hope in trying to convert traditional environmentalists to wholeheartedly support nuclear power, for example: the goal is just as futile as the goal of converting the majority of the world to the values of traditional environmentalism. For the most part, all such efforts will achieve is a pat in the back from those who already agree.
Instead of scoring points among the already converted, I think ecomodernism and future environmental movements, which I believe will emerge, should focus on those who care but haven’t been able to work within existing platforms to channel their energy towards the overall goal: of building a better world for everyone.
An aside about heresies
Nevertheless, I think it is instructive to try to think why there have been so vicious infighting between people who call themselves environmentalists. In Monty Python’s fantastic Life of Brian, there is a brilliant scene where hapless Brian mistakes the activists of anti-Roman People’s Front of Judea for the activists of Judean People’s Front. As explained by Reg, the leader of the People’s Front,
The only people we hate more than the Romans are the fucking Judean People’s Front.
The scene is hilarious because it is firmly based in reality. We humans seem to have a tendency to reserve most scorn not for those who disagree with us in everything, but for those with who we have more in common. The one who disagrees with us in everything is simply an implacable, inhuman enemy, not worth a dialogue. He must only be destroyed; once every enemy is destroyed, a Final Victory will occur for those who share the True Faith.
But the one who agrees with many things yet disagrees on some points is worse: he is a heretic, or a traitor. Heretics may be reconverted to the True Faith and their souls saved; traitors have a reserved seat in Hell.
As you may have guessed already, much of this dichotomy may stem from the Western cultural tradition that is heavily influenced by Abrahamic religions. These religions have clearly defined “us” against “them” and very black and white visions of “good” versus “evil.” (Thanks to the thoughtful student of Hindu environmental activism for pointing this out to me. If someone ever again says there’s no benefit from studying different cultures, I’m going to be quite angry.)
It just may be that such deep, unconscious, culturally embedded frameworks of heretics and traitors may explain some reasons why many environmental activists in the West at least have lately been bashing each other. I, too, shared this worldview: the traditional environmentalists are so much like me in almost every respect that I have hoped to convert them to the One True Faith of atomic powered future. In effect, I’ve been trying to persuade what I see as heretics in order to save their souls. Likewise, many have tried to convert me to renouncing the Atomic Devil.
And when these efforts fail as they usually do, we’re billed as traitors and enemies to the movement, to be excommunicated from the presence of the faithful. To many, it seems to be hard to accept one may be very much for environmental and social justice while still supporting nuclear power. To others, not supporting nuclear power at this juncture seems the very epitome of stupidity or worse. Witness, for example, the regularly surfacing insinuations that those who disagree must be in the pay of some nefarious organisations. It is probably far easier to believe the disagreement stems from selfish motives than to face the fact that there may be persons who agree with you on most but not all things.
That said, there are also legitimate corporate lobbyists interspersed among both “new” and “traditional” environmentalism. There really are people employed by the nuclear industry PR departments, for example. Likewise, the traditional environmental movement works closely – in my opinion, somewhat too closely – with renewable energy industries and their lobbying groups, taking their claims a bit too uncritically. In accordance with the rest of this article, I think we need to be in speaking terms with these lobbyists as well: based on my experience, most of them are decent people who want to do good. But we must not let them define what we want to do. Personally, I believe one reason to support the inclusion of nuclear power within climate change efforts is to keep the renewable industry on their toes: if we exclude potential competition, we increase the risk that these very large and powerful industries may capture the climate mitigation movement entirely. There are a lot of good people in the renewable industries; but they are still companies, still obliged to make a profit, with all the potential consequences this brings in our current form of economic system.
How dangerous the different energy sources actually are? Evaluating the problems of different energy sources is always wrought with controversy, as there is not and can not be a single, universally acceptable method of evaluating the severity of what may be very different impacts. For example, how one should evaluate health effects on children compared to elderly, or health effects on humans to damages to environment?
Nevertheless, some commendable attempts at comparing the dangers of energy technologies have been made. Among the more recent ones is a study commissioned by the European Union and performed by consulting company Ecofys. Known for its pro-renewable and anti-nuclear reports, Ecofys estimated the average so-called “external” costs of different electricity generation technologies in use within the EU. In this context, external costs refer to costs the energy generators do not have to pay, but instead “externalise” to the society as a whole.
The Ecofys study referenced here is not without its problems, but it nevertheless remains an admirable effort at evaluating the dangers of different energy sources on a level playing field. As we can see from the results, even the highest estimate for the dangers and costs of nuclear power comes below the costs of natural gas, and comfortably close to the costs of biomass use – whose radical expansion is one of the keystones of every non-nuclear energy scenario presented by traditional environmental organisations.
The low estimate, on the other hand, comes well below the impacts of solar power. That’s even when the impact of nuclear accidents is factored in.
If we take the Ecofys study at face value, we should probably conclude that the dangers of nuclear energy are on par with dangers associated with most forms of renewable energy. The dangers may be different, of course: renewable energy sources do not experience meltdowns, but they may emit considerable pollution during their construction or use. The end results, however, are similar: both acute and chronic illnesses to people exposed.
It should be noted that the findings of this Ecofys study are in line with findings of a review commissioned by Friends of the Earth UK: in the review of relevant scientific literature, the report concluded that
“Overall the safety risks associated with nuclear power appear to be more in line with lifecycle impacts from renewable energy technologies, and significantly lower than for coal and natural gas per MWh of supplied energy.”
To avert dangerous climate change, we will need lots and lots of low-carbon energy sources. Electricity is perhaps the most important of these, as it is wonderfully flexible form of energy that can replace fossil fuels in multiple applications. Furthermore, it is easy to deliver and we know how to generate it in quantity with very low carbon emissions.
Of all the methods of low-carbon electricity generation, nuclear power is still the single most important. It alone produces far more low-carbon electricity than all the “new” renewables combined. This is an inconvenient fact for those who try to oppose nuclear power while simultaneously opposing climate change. As a result, one hears constantly claims that nuclear power produces greenhouse gases – and that this makes it unsuitable for climate mitigation.
The first part of this claim is true: In fact, no energy source produces energy without greenhouse gas emissions of any kind. There are emissions associated with wind power, and there are emissions associated with solar power. The second part, the inference, is false, however. In all the serious research on the subject, the carbon balance of nuclear electricity is found to be very low. It compares well with wind power and, in fact, tends to be lower than that of solar electricity.
The most common counterargument we’ve heard at this point is the obvious: “Wait, what about uranium mining, or building of nuclear power plants? Surely they contribute a lot of emissions?”
Fortunately, we can say that this counterargument does not hold water. The figures quoted here, and in any serious scientific report, are so-called lifecycle emissions. This means that the figures already include impacts from mining, building of power plants, and so forth. In our opinion, it is somewhat insulting even to think that such obvious emission sources would not be included in any serious calculations.
But one thing that’s not included in these calculations is the additional infrastructure that is required to deliver equivalent level of service. For nuclear power plants, not much additional infrastructure is required, beyond obvious power lines. But if we want to deliver equivalent service – equivalent amount of reliable electricity generation – from variable sources, we most probably are going to need more infrastructure. This can be reinforced electricity grid to transfer energy from places where the wind blows or the sun shines to places where electricity is needed; it can be backup generators that provide power when it’s dark or calm; or it can be wind turbines and solar panels that are part of “overbuild” required to ensure that at least some catch the wind or the sun at all times.
So far, as the share of variable energy sources in electricity grid has remained small, this additional infrastructure is not really needed. The existing grid and existing power plants can cope with the limited variability, although this often incurs extra costs already. But as we expand our low-carbon energy production, we will need more and more infrastructure to cope with increasing variability. This causes both economic and environmental costs, resulting to higher carbon balance than these simple calculations would suggest.
This is one of the reasons why we believe that opposing proven solutions that can provide significant quantities of low-carbon energy is, at this point, a gamble with the climate.

NOTE: graph was updated to the latest data available 12th Jan 2019.
Even at this late hour, when we have mere 35 years to effectively end the burning of stuff for energy, there are some who argue against low-carbon energy generation. One of the more common arguments is that nuclear power plants take too long to build, and therefore they cannot help with the task.
This argument is patently false. While it may be true that building only nuclear may not be enough to stave off dangerous climate change, it is clear that nuclear is one of the best single technologies if we are really serious about combating climate change.
To wit, Exhibit A: historical long-term achievements of low-carbon energy, normalised to account for population differences. We used the widely available and generally reliable BP World Energy Outlook data to first search for the largest increase in low-carbon electricity generation over a 15-year window in each of the country covered; we then divided this increase with the average population of the country during the period.
As a result, we can see that nuclear power is surprisingly effective method for increasing low-carbon energy production. All the top spots in this graph belong to 1970s-80s era nuclear programs. Even the much-maligned Olkiluoto 3, the poster child of anti-nuclear movements worldwide, turns out to be faster than any attempt at wind and solar power combined.
Were we to normalise the results according to metrics that are even more relevant – gross domestic product (GDP) or purchasing power adjusted GDP per capita – nuclear power would look even better. The countries shown above succeeded in unprecedented and unequalled increase in low-carbon energy generation back in the day when they were much poorer than today, and significantly poorer than countries with high renewable energy ambitions. As the world’s poor continue to aspire for higher standards of living, this is an important point.
Of course, renewable installations have been growing fast. It is very possible, and very desirable, that some country will one day take the top spot in this chart with wind and solar installations combined. But it is not today; and we’re in a hurry.
One might also want to argue that the 15-year timescale is unfair: the largest increase in renewable energy has happened over the last decade or less. But decarbonisation is not a sprint, it is a marathon. Nuclear plants take time to plan and build, but permits and plans for renewable energy aren’t instantaneous either. We really need to take the long-term view; besides, had we selected the best five-year period (for example), nuclear energy would have won even more clearly.
All in all, we now need all the options at our disposal. At this point, anything else is a huge gamble with our climate.
