## Resource

In this episode of Climate Debrief, professional engineer and author, Ron Barmby, joins Angela Wheeler to discuss his book Sunset on Net Zero. He questions the scientific, economic, and engineering basis of global net-zero policies. Drawing on physics, real-world observations, and decades of experience, he argues that CO₂’s warming effect is small and diminishing. He also challenges climate models that rely on unverified assumptions. Barmby warns that many green energy solutions are impractical and that net-zero policies disproportionately harm the poor.
