Yesterday at the Canadian Institute for Theoretical Astrophysics (CITA) I gave a talk on humanity’s energy history, the fossil fuel energy system, and potentially climate-safe alternatives:

Travis Rector on fossil fuel abolition
About 90% of climate change is from the extraction and use of fossil fuels. We need to stop. As Chapters 6 and 7 point out, this won’t be easy—especially when fighting against industries that stand to lose trillions of dollars from the energy transition. But the rapid growth of wind and solar shows us that it’s already happening. Our role is to help it happen even faster.
Rector, Travis A. “Preface.” In: Rector, Travis A. Climate Change for Astronomers: Causes, consequences, and communication. IOP Publishing, 2024. p. xxi
Also:
We are at a crossroads in the history of our 4.5-billion-year-old planet. These days in which we are alive are precious beyond measure, especially from the perspective of Earthlings who come after us. Every day the fossil fuel industry continues to exist makes our planet hotter, taking us more deeply into irreversible catastrophe. The only way out is to end the fossil fuel industry; the faster we do, the more we will save… It is incredibly important to fight the fossil fuel industry, which has captured world leaders and international climate negotiations.

Our leaders are killing our kids
Oceans of ink have been spilled arguing that social media and smartphones are the reason young people around the world are not doing well.
While there may well be truth to that, to me the whole discussion seems like an evasion of the real issue: we are living in a world where our leaders are killing our kids, because they are unwilling to act on climate change even though it could bring about the end of our civilization. We live in a world where the people in charge are willing to condemn everyone who follows them to torment and destruction, all because they are unwilling to give up the conveniences of fossil fuels. The ‘leaders’ who are doing this are committing history’s most egregious crime against future generations and the natural world, yet our media and society keep treating them as the best of their kind: deserving of praise, wealth, and fancy state funerals when they reach the end.
The lesson that sends to young people is that the system does not value them in any way, and is happy to sacrifice their most vital interests for the sake of further enriching those who benefit from the fossil fuel status quo – which is not just billionaire fatcats, but billions of consumers in rich societies who take it for granted that big trucks and airplanes are the way to get around and who insist on political leaders who pretend to care about climate change, while being privately committed to keep supporting the fossil fuel industry.
Even the RCMP – an institution that sees itself as an ally (p. 41) of the fossil fuel industry – is warning about how our societal disregard for the interests of the young is fueling instability:
There is a notion of the social contract in which each generation is obligated to consider the interests of those who will come after. This covenant has been totally broken, with the almost inescapable consequence that intergenerational conflict will become more and more severe as the damage we have done to the Earth keeps destroying our ability to provide the well-off with what they feel entitled to.

Taleb on the domain dependence of knowledge
I used to attend a health club in the middle of the day and chat with an interesting Eastern European fellow with two Ph.D. degrees, one in physics (statistical no less), the other in finance. He worked for a trading house and was obsessed with the anecdotal aspects of the markets. He once asked me doggedly what I thought the stock market would do that day. Clearly I gave him a social answer of the kind “I don’t know, perhaps lower”-quite possibly the opposite answer to what I would have given him had he asked me an hour earlier. The next day he showed great alarm upon seeing me. He went on and on discussing my credibility and wondering how I could be so wrong in my “predictions,” since the market went up subsequently. Now, if I went to the phone and called him and disguised my voice and said, “Hello, this is Doktorr Talebski from the Academy of Lodz and I have an interrresting prrroblem,” then presented the issue as a statistical puzzle, he would laugh at me. “Doktorr Talevski, did you get your degree in a fortune cookie?” Why is it so?
Clearly there are two problems. First, the quant did not use his statistical brain when making the inference, but a different one. Second, he made the mistake of overstating the importance of small samples (in this case just one single observation, the worst possible inferential mistake a person can make). Mathematicians tend to make egregious mathematical mistakes outside of their theoretical habitat. When Tversky and Kahneman sampled mathematical psychologists, some of whom were authors of statistical textbooks, they were puzzled by their errors. “Respondents put too much confidence in the result of small samples and their statistical judgments showed little sensitivity to sample size.” The puzzling aspect is that not only should they have known better, “they did know better.” And yet…

Sagan on self-skepticism
Perhaps the sharpest distinction between science and pseudoscience is that science has a far keener appreciation of human imperfections and fallibility than does pseudoscience (or “inerrant” revelation). If we resolutely refuse to acknowledge where we are liable to fall into error, then we can confidently expect that error—even serious error, profound mistakes—will be our companion forever. But if we are capable of a little courageous self-assessment, whatever rueful reflections they may engender, our chances improve enormously.

Canada’s 2023 fires
Oliver Milman writes in The Guardian:
The impact upon the world’s climate will be even more significant than this. According to data from the European Union’s satellite monitoring service, more than 1.7bn tons of planet-heating gases have been released this year by the enormous fires – about three times the total emissions that Canada, a major fossil fuel-producing nation, itself produces each year.
Such huge emissions, eclipsing in a single year any measure, however ambitious, to cut pollution from cars or factories by a country like Canada, are a major drag upon efforts to stem the climate crisis. The majestic boreal forests, much like the Amazon rainforest that now emits as much carbon as it sucks up and is tipping towards becoming a savannah, suddenly appear to be a danger to the world’s climate rather than a key safeguard.
The world has ignored the imperative to stop worsening climate change through fossil fuel use for at least three decades now. The planet is starting to gravely reflect that mistreatment, and doing so in ways that worsen future disruption.
A broad-ranging talk with James Burke
As part of promoting a new Connections series on Curiosity Stream launching on Nov. 9, I got the chance to interview historian of science and technology, science communicator, and series host James Burke:
The more interview-intensive part begins at 3:10.
Reviewing an unreleased book and TV show
While it won’t help with my rent, I nonetheless have some very interesting work for the next few days.
I am doing a close read twice of Professor Peter Russell’s forthcoming memoirs, which has been a privelege because of the respect I have for him as a thinker and a person, and a joy because of their colour, humour, and personality.
I am also previewing a new series of James Burke’s TV show Connections, which previously ran in 1978, 1994, and 1997. I have seen those old shows many times, and I thought a lot about his book The Axemaker’s Gift back in high school. I have the chance to interview him from Monaco on Wednesday, so I am giving the new material a careful viewing and thinking through how to make the best use of the conversation. There is scarcely a person I can think of who has a more educated and wide-ranging understanding of the relationships between science, technology, and human society. Since human civilization is presently hurtling toward a brick wall which threatens to rather flatten us all, it may be invaluable to get Burke’s views on how a defensive strategy from here can be undertaken.

Envy of the high-statused
Our ill feeling toward high-status players has been captured in the lab. When neuroscientists had participants read about someone popular, rich and smart, they saw brain regions involved in the perception of pain become activated. When they read of this invented person suffering a demotion, their pleasure systems flared up. Psychologists see this effect cross-culturally, with one study in Japan and Australia finding participants took pleasure in the felling of a ‘tall poppy’: the higher their status, the greater the enjoyment of their de-grading. The most venomous levels of envy were reported when the poppy’s success was ‘in a domain that was important to the participant, such as academic achievement among students’ – when they were rivals in their games.
An yet, as we’ve learned, we’re also drawn to high-status people: we crave contact with the famous, the successful and the brilliant. So our relationship with elite players is thunderously ambivalent. On one hand, we gather close to them, offering them status in order to learn from them and, in the process, become statusful ourselves. On the other, we experience grinding resentments towards them. This, perhaps, is the result of the mismatch between our neural game-playing equipment and the massively outsized structure of modern games. Our brains may be specialized for small tribal groups but today – especially at work and online – we play colossal games in which poppies loom over us like redwoods. Status is relative: the higher others rise, the lower we sit in comparison. It’s a resource and their highly visible thriving steals it from us. The exceptions we make tend to be for ambassadors from our own groups: artists, thinkers, athletes and leaders with whom we strongly identify. They seem to symbolize us, somehow. They carry with them a piece of our own identity, a pound of our flesh – so their success becomes our success and we cheer it wildly. To our subconscious these idols are fantastically accomplished versions of us: our copy, flatter, conform cognition overrides our resentment.

Another example of Canada’s dishonest climate policy
These linguistic evasions demonstrate both our continuing lack of seriousness about climate change and how the public policy agenda remains captured by the fossil fuel industry protecting its narrow interests:
Western premiers push back as Guilbeault calls for ‘phase-out of unabated fossil fuels’
We know that greenhouse gases are the cause and there is no solution to climate change without fossil fuel abolition, but we are stuck talking about a “phase down” instead of elimination, and using the magical idea of “abated” fossil fuels to use a technology that does not exist at scale (carbon capture and storage) to justify continued fossil fuel development.
