I have a new paper in Dialogues on Climate Change exploring climate outcomes under current policies. I find that we are likely headed toward 2.7C by 2100 (with uncertainties from 1.9C to 3.7C), and that high end emissions scenarios have become much less likely

A useful new review by Zeke Hausfather One error-includes Sarofim et al. 2024 Omits 4 other studies from 2024-UNEP, CAT, IEA, Scafetta After updating, good news, from 2019 to 2025 "current policies" central projections of 2100 global temperatures have decreased from 2.8C to ~2.6C

In Ep. 242, Tim Gould of International Energy Agency returns to discuss the insights from their annual report, the World Energy Outlook, including the implications of fossil fuel demand peaking and renewables becoming the dominant source of electricity globally within 5 years. xenetwork.org/ets/episodes/e…

🚨 Trump’s 2025 Trade War Will Backfire—Here’s Why Canada Holds the Cards 🇨🇦🔥 Here’s how: 🧵👇 1. Make America Great Depression Again (MAGDA) is Happening 📉💀 The Smoot-Hawley Tariffs of 1930 transformed an economic shock into what we know as the Great Depression. Trump is

Heat pumps are one of the cheapest and most versatile ways of decarbonizing heating. In Ep. 243, heat pump policy expert Richard Lowes outlines how to design policies to encourage the adoption of heat pumps everywhere. xenetwork.org/ets/episodes/e…

In Ep. 244, Professor Mariana Mazzucato of University College London shares essential insights about what makes for effective, enduring, and equitable green industrial policy. xenetwork.org/ets/episodes/e…

In Ep. 245, Julian Leslie of National Energy System Operator rejoins us to discuss how Great Britain is developing a coordinated plan to evolve ALL of its energy networks toward net zero electricity by 2030 and complete decarbonization by 2050. xenetwork.org/ets/episodes/e…

In Ep. 246 we speak with @bowenchris The Hon. Matt Kean Tristan Edis and Alex Wonhas about how the Australian government is working with the grid power sector to plan and execute its #energytransition while maintaining system reliability. xenetwork.org/ets/episodes/e…

In Ep. 247, we continue our miniseries on Australia by exploring their innovations in pre-commercial technologies, deep DER integration, VPPs and microgrids, and passive building techniques. xenetwork.org/ets/episodes/e…

In Ep. 248, International Energy Agency analyst Heymi Bahar shares findings from their recent comprehensive report, “The Future of Geothermal Energy.” By 2050, geothermal could deliver as much power as the US and India combined consume today. xenetwork.org/ets/episodes/e…

In Ep. 249, we continue our miniseries on Australia xenetwork.org/ets/category/a… by featuring three researchers and entrepreneurs who are advancing solar technology R&D, including the “father of solar cells,” Martin Green. And it turns out CSP isn’t dead! xenetwork.org/ets/episodes/e…

In Ep. 250, Thane Gustafson rejoins us to discuss Russia’s failed opening to the West, how the sanctions against Russia have succeeded and failed, what Putin’s motivations in Ukraine are, and Russia's future as global energy transition efforts accelerate. xenetwork.org/ets/episodes/e…

We saved the best for last! In Ep. 251, we conclude our 6-part miniseries on Australia with a look at how, by 2027, South Australia Power Networks will operate the first gigawatt-scale grid in the world with a 100% variable renewable energy supply. xenetwork.org/ets/episodes/e…

⚠️General warning on any report about the limits of Al: If it isn't already, the report will be outdated soon after publication. Models are improving at an incredibly rapid rate. Look at the change in model performance in only 2 years! Similarly, tooling is improving for Al

I really like the term “context engineering” over prompt engineering. It describes the core skill better: the art of providing all the context for the task to be plausibly solvable by the LLM.

In Ep. 252, Emily Grubert and Josh Lappen join us to discuss the British government’s takeover of British Steel, and steelmaking in the “mid-transition” amid the geopolitical tensions of a global tariff war. xenetwork.org/ets/episodes/e…

In Transition Show @[email protected] Ep. 253, Michael Grunwald returns to the show to discuss his new book, “We Are Eating the Earth.” We focus on the bioenergy side of ag in this conversation, and ask if any of those solutions are truly ‘renewable’ or ‘carbon-neutral.’ xenetwork.org/ets/episodes/e…

In Ep. 254, Nicolas Fulghum joins us for a deep dive into the data in Ember’s Global Electricity Review 2025 report. Not only has the energy transition gone global, it’s accelerating so quickly that global power-sector emissions may be close to peaking. xenetwork.org/ets/episodes/e…

“China isn’t just sort of an analytical problem, it is the political problem…. The development of China is the master key, I think, to understanding modernity…. And without it, you just don’t have a hope of grasping what’s going on.” podcasts.apple.com/us/podcast/sin…
