Climate on the Edge

As a climate investor focused on energy transition and carbon dioxide removal, I've spent years understanding and supporting technologies that drive decarbonization. But lately I've grown concerned that our progress isn't happening fast enough. The urgency of our situation. Which has become very apparent has left me curious about what else is out there.That's why I was so excited to speak with Kelly Wanser, Executive Director of SilverLining. SilverLining is a nonprofit organization dedicated to addressing climate risks through advancing research and equitable governance around solar radiation management. Kelly is an absolute powerhouse here and a true pioneer in this field. Our conversation will get into how SRM might work, where it's at today, what's needed to advance the field and why organizations like SilverLining and its backers believe that it should advance. We'll explore the economic and practical aspects, including concerns about SRM's affordability and the actual, very real logistical challenges of deploying any form of SRM responsibly on a global scale. Kelly is one of the world's most influential figures on SRM and climate intervention beyond emissions reduction. I hope this conversation is as thought-provoking for you as it was for me.Leave us a rating and review on Apple Podcasts ⭐️For more about the show and more information about episodes, visit Climate on the Edge.Follow us on X and Linkedin.Supported by emrgnce - innovative minds exploring climate’s next frontier.

In this episode I explore the controversial topic of solar geoengineering with Dr. Holly Jean Buck, and Dr. Will Burns, two of the most thorough and interesting thinkers out there when it comes to the topic. Specifically they talk me through the question of “should we ban SRM research”. There’s a lot these two experts disagree on about SRM, and their back and forth really expanded my thinking on the topic. Together, we break down what SRM is, how it might work, and the different approaches within SRM, such as stratospheric aerosol injection and marine cloud brightening.This episode provides a nuanced look at SRM as part of the climate action toolkit, I hope it helps you think critically about the role it might play, as it did for me. Episode ResourcesHolly’s Article on SRM researchSRM Non-Use AgreementWhite House statement on SRM (2023)Wil’s work on the SRM research ecosystem Alameda, California Suspends MCB ExperimentGuest-Suggested Articles-WilClive Hamilton- Geoengineering and the Politics of ScienceHolly’s Book After GeoengineeringHollyTaiwo and Talati- Who are the Engineers? Wiley Carr- Vulnerable Population’s Perspectives on Climate EngineeringTimestamps01:26 Urgency of SRM02:25 Introducing Holly and Will22:06 State of SRM Research29:39 Global Players in SRM43:12 Rules in SRM Governance46:34 Challenges of Private Sector Involvement55:22 Conspiracy Theories and Public Perception01:04:00 Future Prospects01:07:02 Lightning RoundLeave us a rating and review on Apple Podcasts ⭐️For more about the show and more information about episodes, visit Climate on the Edge.Follow us on X and Linkedin.Supported by emrgnce - innovative minds exploring climate’s next frontier.

In this episode of Climate on the Edge, I’m diving into a topic that’s been top of mind lately—what happens if the political winds shift, and we lose momentum on climate policy? With the election approaching, there’s a lot of talk about the potential rollback of the Inflation Reduction Act and what that could mean for climate infrastructure funding. I recently attended Voyagers’ Annual General Meeting, where industry experts discussed the resilience of climate tech companies in the face of political uncertainty, and it got me thinking.One of the most interesting moments at the AGM was Nat Bullard’s presentation, where he highlighted how institutional predictions about renewables have consistently been wrong—renewables continue to grow exponentially. Even with concerns about reduced subsidies, other speakers made a strong case that the best climate companies can thrive on their own. They argued that while subsidies are helpful, they’re not the sole reason for success. So, when is it really safe for investors like us to dive into climate tech?In this episode, I also take a look at the bigger picture when it comes to subsidies. Industries like oil, gas, and agriculture have benefited from billions in government support over the years, and climate tech should be no different. While some fear a shift in political power could direct subsidies back toward fossil fuels, I believe waiting for certainty could mean missing out on huge opportunities. We need to rethink how we view subsidies and invest in the companies building our future, regardless of political changes. Thanks for listening, and as always, I’d love to hear your thoughts!Episode ResourcesNat Bullard’s website w/ links to past presentations: https://www.nathanielbullard.com/Timestamps00:00 The Election…01:03 Insights from the Climate Tech Venture Fund Meeting02:56 The Reality of Subsidies + Wild Statistics09:15 Political Risks and Opportunities AheadLeave us a rating and review on Apple Podcasts ⭐️For more about the show and more information about episodes, visit Climate on the Edge.Follow us on X and Linkedin.Supported by emrgnce - innovative minds exploring climate’s next frontier.

As biodiversity faces mounting risk from the explosion of H5N1 bird flu and climate change, can investing in nature-focused startups unlock new ways to safeguard our planet’s species and ecosystems?On this episode of Climate on the Edge we’re joined by Tom Quigley, who discusses his unique journey from conservation biology to technology and eventually becoming a venture capitalist focusing on biodiversity. His experiences in field conservation then tech startups shaped his understanding of leveraging technology for conservation challenges. The conversation explores concepts of ecosystem services, biodiversity measurement, land-use change, and the interplay between technology and nature. Quigley emphasizes nature's resilience, existing initiatives for biodiversity protection, and the future of nature tech. He also shares personal reflections from his career working to support nature, and how he hopes to see much more of the finance world join the trend of investing in “nature-tech”. 02:19 From Conservationist to Tech Enthusiast07:51 Challenges and Opportunities in Nature Tech11:41 Understanding Biodiversity and Its Importance18:31 The Economic Value of Ecosystem Services25:47 Complexity of Measuring Biodiversity30:10 Nature as Humanity's Defense Against Climate Disaster32:20 The Role of Mangroves in Storm Protection33:24 Key Drivers of Biodiversity Loss36:49 Understanding Zoonotic Diseases42:12 Hopeful Solutions and Nature's Resilience46:06 The Future of Nature Tech and Biodiversity Investments54:56 Optimism for the FutureEpisode ResourcesSuperorganismTheir blogBook Review on ‘Legibility’Bat Fungus Leads to Population Loss‘Terrifying’ Article on H5N1’s Effect on BiodiversityWWF ReportSharkwater DocumentaryLeave us a rating and review on Apple Podcasts ⭐️For more about the show and more information about episodes, visit Climate on the Edge.Follow us on X and Linkedin.Supported by emrgnce - innovative minds exploring climate’s next frontier.
