217: Canopy of Titans – Greenwashing and the Great North American Temperate Rainforest with Paul Koberstein

Listen on Apple Podcasts

What if the world’s most powerful climate solution is being logged away while politicians and industry groups feed us misinformation? How can an ecosystem store three times more carbon per acre than the Amazon rainforest? Why has the international science community remained largely silent about the destruction of temperate rainforests? Our conversation with Paul Koberstein, co-author of “Canopy of Titans – The Life and Times of the Great North American Temperate Rainforest” tackles these urgent questions head-on. The Great North American temperate rainforest stretches 2,500 miles from northern California to Alaska, making it the largest intact temperate rainforest on Earth. Yet this carbon-dense ecosystem faces ongoing threats from industrial logging, greenwashing campaigns, and policy decisions that prioritise short-term profits over long-term climate stability.

Paul shares his journey from camping beneath old-growth Douglas firs as a child to becoming an investigative environmental journalist covering forest issues for over 40 years. Our conversation examines the troubling parallels between the timber industry’s tactics and those employed by fossil fuel and tobacco companies. We discuss how scientists like Dr Beverly Law faced persecution for publishing research on how forests benefit the climate. Paul explains the “global blind spot” that has allowed temperate rainforest logging to continue largely unchallenged, even as the international community rallies to protect tropical rainforests. The book reveals how industry-funded research has shaped policy debates and obscured the true climate impact of logging these ancient forests.

Despite the sobering realities, Paul offers hope through examples of successful grassroots activism. When thousands of people raised their voices against Drax’s expansion into California, the project was cancelled. Our conversation also touches on the dramatic shift in US climate policy under different administrations and what this means for forest protection efforts globally. Paul’s advice is clear: to save a forest, you must work at it every day, but to destroy it, you only need to do it once. This episode is essential listening for anyone who cares about climate action, forest conservation, and cutting through corporate greenwashing.


In Canopy of Titans, Paul Koberstein and Jessica Applegate examine the global importance of the Pacific Coastal Temperate Rainforest that stretches from Northern California to Alaska. Their urgent and authoritative account sets out the threats facing a vital environmental resource, and celebrates the beauty and complexity of one of the world’s great forests.
