Is the 1.5°C temperature target helping or hindering climate action? In this episode of Saving the World from Bad Ideas, Mark Lynas sits down with his co-authors Kwesi Quagraine (climate scientist at NCAR) and Erle Ellis (professor at University of Maryland Baltimore County) to discuss their groundbreaking new paper published in Nature that proposes a complete rethinking of how we measure climate progress.

The team argues that global average temperature targets — the organizing principle of climate policy since Paris 2015 — are intangible, unactionable, and increasingly counterproductive now that we've essentially crossed the 1.5°C threshold. Instead, they propose the Clean Energy Shift (CES) — a simple, measurable metric that tracks how fast clean energy is displacing fossil fuels in real time.

🧠 Topics Discussed:

🌡️ Why global average temperature targets are intangible and don't translate into clear policy actions

🔢 The problem with "1.5 to stay alive": What happens when you cross a threshold framed as a limit of safety?

📊 Introducing the Clean Energy Shift (CES): Growth rate of clean energy minus growth rate of total energy demand

🔌 Why clean energy is now the cheapest option in most developing countries

🌍 How regional climate impacts differ dramatically from global average temperature (Africa vs Europe vs small islands)

🎯 Why "percent clean energy" should replace temperature as our north star metric (aiming for 100%)

📉 The challenge of measuring energy: Primary vs useful energy, and why efficiency gains complicate the numbers

⚡ Heat pumps, electric vehicles, and electrification:

💡 Why clean energy shift creates positive competition between countries (not just climate guilt)

🗳️ Why clean energy targets need to enter UNFCCC discussions alongside temperature goals

🔬 The data challenge: Why IEA and others need to release standardized, open-access energy data

📐 The paradox of our time: Passing "safety limits" while developing real solutions

🔭 The narrative shift from "avoid catastrophe" to "build clean energy abundance"

👨‍🏫 Guest Bios:

Kwesi Quagraine is a climate scientist at NCAR (National Center for Atmospheric Research) and former senior lecturer at the University of Cape Coast, Ghana, where he taught physics, meteorology, and atmospheric science. Originally from Ghana, Kwesi brings vital perspectives on how climate policy impacts developing nations and expertise in climate modeling, including solar radiation management research.

Erle Ellis is a professor of geography and environmental systems at the University of Maryland Baltimore County. His work with the United Nations Development Program's Human Development Report focuses on aspirational indicators for making a better future. Erle has spent decades studying global environmental change and teaching students how human societies interact with planetary systems.
