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.

Can we find a middle ground between those who see the EU's wolf downlisting as a catastrophe and those who celebrate it as good news? The debate around wolf conservation in the EU has become frustratingly polarised, with both sides 'crying wolf' about the consequences of changing protection status. It's time to step back and look at the evidence.

When dealing with controversial subjects like this, it is important to be factual and follow the evidence. So I was delighted to have the opportunity to talk about it with Dr Hanna Pettersson, one of the most prominent early career voices in interdisciplinary conservation. Hanna is the lead author of a paper titled 'Now What? The Conundrum of Successful Recovery of Wolves and Other Species for European Conservation', co-authored with Professor Erica von Essen, who was also a guest on the acclaimed episode 163.

During our conversation, we discuss the success conundrum in conservation, the difference between ecological and social carrying capacity, and why we need to think about future pathways rather than looking back. We also talk about the role of legal hunting in reducing poaching and the importance of working with local communities who have lived alongside wolves for generations. Of course, there are larger systemic issues underneath and we don't shy away from discussing those as well, including inequality as a driver of biodiversity loss.

On my podcast, we talk a lot about coexistence with large carnivores and the challenges it poses. Some of those challenges might seem insurmountable to some. To shed some light on overcoming these hurdles, I contacted Helen Arusoo, an Estonian nature journalist and the leader of the National Animal Working Group. In this conversation, we talk about how Estonia overcame these hurdles and created something that I would consider the gold standard of coexistence with large carnivores.

Unsurprisingly, the majority of our time was spent discussing wolves as they seem to be the most difficult carnivore species to coexist with, at least in the northern hemisphere. However, we did discuss other large carnivores like bears too. Our conversation focused mostly on social and cultural factors. We also touched on the European Commission's proposal to lower the protection status of wolves, something we’ve discussed extensively in one of the previous episodes.

It was a wonderful conversation and I enjoyed speaking with Helen. Her profound understanding of the challenges of coexistence is impressive. She presented a deeply thought-out perspective and I can only wish that more people who care about wolves could learn from her experience and the Estonian model of coexistence with large carnivores.
