The Climate Expert is a five-volume primer series for young professionals working in climate, sustainability, and ESG. Each volume covers one region of the field in plain language: how it works, where it came from, what the law says, and what a careful professional should doubt. The series is published by Climate Expert Publication, an editorial collective committed to unbiased, knowledge-based information for students, young professionals, and everyone.
This is the second volume. Climate Risk is the working vocabulary of finance, strategy, and supervision in 2026. If you read TCFD reports, IFRS S2 disclosures, or NGFS supervisory scenarios as part of your job, this book is the primer that explains where this language came from, what it means, and which parts of the framework are now being contested.
The book is built around the three-way taxonomy Mark Carney introduced in his 2015 Lloyd's of London speech: physical, transition, and liability risk. It traces how that institutional architecture is being repriced in 2026 by the SEC's March 2025 rule withdrawal, the EU's February 2026 Omnibus simplification, and the December 2025 retraction of the Kotz damage function used in NGFS Phase V scenarios.
Inside this volume:
- The twelve terms a professional needs before opening a TCFD or IFRS S2 report
- How physical, transition, and liability risk show up in a real portfolio
- What NGFS Phase V scenarios actually are, what they are not, and what the Kotz retraction means for stress testing
- The ECB, Bank of England, and US Federal Reserve climate stress tests, and what supervisors concluded
- The post-Omnibus disclosure map: IFRS S2, ESRS E1, UK SDR, California SB 253 and SB 261
- The litigation that has turned climate disclosures into legally consequential documents, including Milieudefensie v Shell and KlimaSeniorinnen v Switzerland
- Five steelmanned critiques the framework should hold up under
