As the climate change debate has advanced, the arguments surrounding it have become more subtle. Outright denial of the climate problem is rare - so rhetoric has shifted to delaying urgent action. In this review of a paper by Steinberger, Lamb et al, I run down the new "discourses of climate delay"

Why should we listen to scientists? Well, because they're right a lot of the time. But also because - ideally - the institutions of science embody values that everyone can agree are good in a system for working out what's true.

How can machine learning and artificial intelligence help us in the fight against climate change? I explore literally dozens of ideas for possible applications of ML algorithms in this episode.

I interviewed David Gerard, author of the cryptocurrency blog and book of the same name "Attack of the 50ft Blockchain", as well as a new book "Libra Shrugged" about Facebook's attempt to develop cryptocurrencies. We talked about Bitcoin, its flaws, its origins, and its future.

I have generally held back on talking about bitcoin - because I'm super opinionated and it's one topic that generates a lot of heated discussions - but I finally let it all go in this one, lengthy rant episode. Think of it as therapy... and if you disagree, get in touch.

In The Coal Question, Jevons - alongside realising that we needed a transition to renewable energy 150 years ago - posed the efficiency paradox. Using energy more efficiently motivates you to use more energy. Can energy efficiency "rebound" and backfire like this in real systems? That's the question we explore in this episode.

In this episode of our series on energy efficiency, we are going to talk about industrial applications - how we can improve the way that high-energy industries and difficult-to-decarbonise sectors use energy.

It's a smorgasboard of climate news as global emissions rebound, slippery definitions of Net Zero abound, the Green Homes Grant collapses, and there's controversy over a Cumbrian coal mine.

In the second part of our series on energy efficiency and its role in combatting climate change, we talk about how buildings can be made more energy efficient... and some of the factors that prevent this from happening.

Sigh. Yeah I did a thing about the Gamestop, meme stocks, financial asset bubbles, and so on, if only so that these opinions don't have to rattle around in my head taking up space.
