Chris Stark: CEO UK's Climate Change Committee; climate policy, NetZero, adaptation, innovation, cost-benefit and what we should be doing
Chris Stark is the Chief Executive of the UK’s Climate Change Committee. The committee is an independent statutory body which advises the UK and developed governments on emissions targets and preparing for and adapting to the impacts of climate change. I think he is one of the most important and thoughtful thinkers on climate change policy today.
We discuss what is most misunderstood about climate policy, the likely co-benefits and the scale of investments needed especially in the UK in replacing “old inefficient stock”.
What positives/negatives came out of COP26 (recent international climate conference) and what to hope for in COP27 and beyond. Why COP26 might have been considered a corporate COP as a criticism but why that might not be bad.
Why sector specific strategies might be a better plan than a focus on carbon tax.
Why adaptation or resilience has been a bit of a “Cinderella” in climate discussions. What the science suggests is already baked into 2050 scenarios and so what we should be thinking about adaptation as well as mitigation.
The complexities and challenges around “behaviour change” and why it’s not a great term. Why we might not need a complete culture change (in the sense of changing lifestyles) but the intersection of behaviour and technology. (For instance, still driving cars but electric cars on a decarbonised grid.)
Why a sense of fairness is one the most important climate policy (political economy) considerations and what we should think about in terms of climate impacts falling unequally across countries and peoples.
What role finance has to play. Chris references the work of Nick Robins here.
We discuss:
Climate assemblies (and why Chris changed his view on them)
Divest/engagement strategies
Carbon offsets
Carbon taxes
The role of nuclear
Land use
Road charging
And we end with advice Chris has for people.
Transcript and video is available here, along with links to the CC and Nick Robins work.

David Spiegelhalter: COVID statistics, thinking about risk in life and medicine
David Spiegelhalter is an expert on medical statistics. He was the president of the Royal Statistical Society and is Chair of the Winton Centre for Risk and Evidence communication. He is also a World Champion, in a version of pool called Loop and hosts his own podcast, Risky Talk. David has a new book out (with Anthony Masters), COVID by Numbers, which is an excellent book on COVID statistics. This follows his previous bestseller, the Art of Statistics.
David discusses what was most surprising and misunderstood about COVID statistics. David emphasises how numbers can be emotional and weaponised and what we can do to protect ourselves.
We chat about what thinking about risk and techniques we should teach children and think about in every day life. Ideas such as baseline risk and absolute vs relative risk.
We think about unintended consequences, the agency challenges of regulators and how to think of a range of risk. David explains fat tails and extreme values and that, for instance, AI risk is an extreme existential risk but perhaps over rated.
I learn about the “Rose Paradox” and “Cromwell’s law”, in statistics. The Rose paradox suggests policy might be useful at a general population level but not at an individual basis. For instance, government messages about drinking less and things like that can be rational at the population level and yet it's also rational for individuals to take no notice of it.
Cromwell’s law implies many life events are not 0% or 100% and you should take that into account in decision making. Or, in plain English, you should always imagine there's something you haven't thought of.
We discuss the risks of alcohol and touch on air pollution and cholesterol (statin drugs), and how to think about medical statistics.
David explains the attraction and beauty of stained glass art.
David ends with life advice about enjoying life and taking (good, well-managed) risks in order to have a fulfilling life.

Stephen Unwin: Theatre Over The Decades, What Disability Teaches Us
Steve Uwin is a theatre director and writer. Amongst many accomplishments he has been the artistic director of the Rose theatre, founder of ETT, English Touring Theatre. He is also chair of the charity Kids, which provides services to children with disabilities.
We speak about whether we need language to be human and what non-verbal people teach us.
We chat on how theatre has developed over the decades and Steve’s appreciation of Brecht and the Berliner Ensemble. We touch on Steve’s experience of theTraverse theatre, dealing with the very different stakeholders of the Rose Theatre; and how European theatre, realism and London has influenced theatre over the decades; what’s enjoyable about theatre over film.
Steve discusses how much of liberal progressive thinking may overlook the history and challenges of disability. While contested, we chat about the possible roots of this in the 18th century enlightenment and its influences today. We talk about the importance of self-advocacy but also the challenges of self-advocacy if you are - for instance - non-verbal.
Steve talks about going viral on Twitter around “mock gloom” and disability. He also provocatively suggests five of the greatest artists of the last century.
We comment on:
Bob Dylan
The artist Piero della Francesca
And what he has in his library of thousands of books
And finish with his current projects and life advice Steve has.
To let you know… The audio is a little crackly on Steve’s side. Apologies in advance.
It’s still listenable, but there’s also a transcript if easier, here. Enjoy. Thanks.

Zeke Hausfather: State Of Climate Science, Energy Systems, Post COP26, Tipping Points, Tail Risks
Zeke Hausfather is a climate scientist and energy systems analyst whose research focuses on observational temperature records, climate models, and mitigation technologies. He spent 10 years working as a data scientist and entrepreneur in the cleantech sector, where he was the lead data scientist at Essess, the chief scientist at C3.ai, and the cofounder and chief scientist of Efficiency 2.0. He also worked as a research scientist with Berkeley Earth, was the senior climate analyst at Project Drawdown, and the US analyst for Carbon Brief. Follow his Twitter for his climate thoughts.
We discuss:
What is most misunderstood about climate science today.
Why many doomsday scenarios are unlikely but yet serious damage from climate is happening now.
Why scientists have been poor in communicating what is mean by tipping points with respect to climate.
How he thinks about climate “tail risk” and how tail risk diminishes the less heating happens.
The problems with “averages” and how there is uncertainty not only about our amount of emissions, but the sensitivity of the climate to our emissions.
Why climate is better thought of as a gradient rather than point thresholds.
The problem with climate economics due to time horizons, long time horizons and the discounting models economists use.
Zeke’s view on the range of different projections coming out post COP26 and what they mean.
Zeke’s thoughts on:
-degrowth
-carbon tax
-techno-optimists
-nuclear power
-carbon offsetting
-divestment movement
-gas as a transition fuel
-green New Deal
-Bjorn Lomborg
Zeke finishes with advice for people who want to be involved in climate.

Aella: escort work, home school, rationalism, circling, working in a factory, losing faith, polls and endless questions | Podcast
Aella is perhaps most famous on twitter for shining a light on the life and economics of Camgirls and escorts; and asking challenging questions. But her independent research is larger than that and has encompassed reporting on LSD and psychedelics use, circling, the nature of faith, and enlightenment. She grew up homeschooled in a fundamental Christian household before leaving home at 17.
The transcript and conversation includes adult themes and mild profanity from Aella and is recommended 18+.
We discuss what is most misunderstood about escort work and the additional needs of men such as emotional intimacy. How Aella thinks of her own compartmentalisation.
What you should say about male anatomy size. How insecurity can go both ways on male thinking on size.
What Aella thinks about Twitter and making questions and polls.
What it was like to have ideas you took for granted completely turned on their head. For instance, what she was taught to think of gays.
We chatted about her interest in psychedelics, speaking to people who think they are enlightened and spirituality. And what that intersection with rationality is for her.
She discusses several viewpoints of the Rationalist community and her views on Effective Altruism. Her thoughts on archaeology and thinking about moral arguments in their place in time.
Why she feels to strongly about home school.
Her thoughts on losing faith.
What it was like working in a factory, and what the point of secret messages she scratched at her work were.
How she has struggled with cultural norms.
How she answers some of her own questions:
You're in a room with 10,000 people. You get to ask three binary questions. Yes or no. For each question, the people who answer the question according to the way you want, they stay and the people who don't leave the room. What do you ask?
We play underrated / overrated on these topics:
Accordion
Ballroom Dancing
Pronouns
Abalone
Sweating on command
She talks about emotional pain and tells me what the practice of circling is all about.
We end on what her research interests are and what her life advice is.

Meaghan Kall, epidemiologist: COVID advice, Long COVID, vaccine waning, disability, HIV, social determinants of health; career advice
Meaghan Kall is an epidemiologist at what used to be known as Public Health England but is now the UK Health Security Agency. She and her colleagues have been working flat out for two years producing some of the world's best COVID data.
We speak about annoying and funny COVID myths.
She gives her view on COVID vaccine waning, Long COVID and risk in children; and how we are going to come to terms with COVID as an endemic disease (think about managing flu, although with different outcomes).
We dive into what it means to be an epidemiologist and think about the social determinants of health. With the lens of looking at HIV epidemiology, we discuss how certain populations are more adversely impacted.
We discuss what caring for disabled children as meant for us and how that insight is another facet of what it means to be human.
We think about what “expected value” means and how science can not answer matters of policy which have to be decided also by thinking of our values and other trade-offs.
Meaghan gives the advice she is currently giving family and friends and ends with some thinking on life career advice.

Clare Montagu: Running a hospice during COVID, how to die well, being a special advisor to government; economics of a hospice.
Clare Montagu was the Chief Operating Officer of one of London’s largest hospice groups, Trinity Hospice. Before that, she was a UK government minister special advisor.
We talk about the challenges and joys of running a hospice. Much of great hospice care is looking after people in their own homes and in the community. Hospice care goes beyond the medical. For instance, letting a patient die in the garden under a tree because that’s their wish. This is care a hospital can not give. The hospice is staffed 24/7, pets can come, family can stay. The hospice is part of the community.
We chat about the importance of death admin. You don’t want to have your stash found by your parents or the state to take your inheritance estate. We speak on why Clare uses straight forward language about death and why we don’t talk about death enough.
Clare reflect on the challenges of COVID and gives her insights into how difficult running the hospice during the pandemic. She gives a sense of what being on the frontlines meant. How to find protective supplies, mortuary bags and and the lack of plans from the state.
We discuss the economics of a hospice. UK hospices are not state funded but mostly funded by charity. Clare had a GBP15m operating budget or closer to GBP10m for healthcare operations (excluding the costs of running charity shops etc) this looked after 2,500 - 3,000 people in a typical year. (In a year, in the UK about 9,000 people die for every 1 million of population; London has c. 9 million population and so 80,000 Londoners die very year).
We debate the difficulty of what funding a minimum service hospice would be like.
We discuss the challenges of state capacity decisions in the light of swine flu and why governments will always tends to spend on a problem now rather than have insurance in stock piles.
Clare gives insights into the life of a special adviser, some of the highs and lows and the comedy moments, and some of the policy she is proud of (helping Children in care).
Clare suggests that while governments often get things very wrong, they are also have to deal with particularly conflicted issues and trade-offs such as security versus liberty.
Clare has volunteered at a charity doing a manual warehouse job recently and she offers insights into that type of job and we discuss jobs that can have “purpose” and jobs where it is difficult to think you are on a “mission”
Finally, Clare reflects on how to have a good death and her life advice. “show up and do something about the stuff that you care about”.
