2021 Discussions:

July 11th: Youth to Power: In the words of Greta Thunberg

On July 11, Paul Litwin facilitated a great session focused on the activism of famous climate advocate Great Thunberg.

Back in 2018, the climate movement was searching for a leader and out of nowhere emerged a 15-year old girl from Sweden, Greta Thunberg. Greta started skipping classes on Fridays to sit outside the Swedish Parliament to protest her country’s inaction on climate change. Later that year, she spoke at the UN Climate Action Summit in Poland and since that time has given speeches to the EU, Davos, the UN, and the US Congress. In 2019, she was named Time Magazine Person of the Year.

Greta is famous for pulling no punches and calling out leaders’ lies, inaction, and intransigence. In this session we will watch several of Greta’s speeches and videos including Greta’s speech at the World Economic Forum in Davos in 2020, her Earth Day message in April of 2021, and a few other gems. We can learn a lot from this amazing young woman.

June 27th: Climate Solutions 101

Earlier this year, the Project Drawdown team released an excellent educational series focused on the solutions to the climate emergency. In this discussion series, Scott Henson (co-founder of Drawdown Seattle and the Seattle Climate Change Meetup group), facilitatated a discussion on the first two of the six units discussing the solutions we have in hand today that can actually reverse global warming.

June 13: Let’s Talk Waste-to-Energy as a Climate Solution

Following up from the March 28th presentation about waste, there were many questions about Waste-to-Energy (WTE) and the climate and environmental implications. This discussion with Philipp Schmidt-Pathmann was a dedicated follow-up discussion focused completely on WTE. This Q&A style session (with a 15-minute introductory overview) was structured so you can learn more about technology, functionality, integration, planning, and everything that you wanted to know about thermal treatment of waste.

Links from the Discussion: 15 minute overview video, Zoom recording, PDF of presentation, PowerPoint, and curated chat with questions and resources.  Original Meetup here.

Suggested Reading & Resources:

Waste-to-Energy on the Project Drawdown Web Site. In a sustainable world, waste would be reduced from the outset and composted, recycled, or reused. The current reality, however, is that cities and land-scarce countries face a dilemma about what to do with their trash. Waste-to-energy is a transitional strategy for a world that wastes too much and needs to reduce its emissions.

Scientific Truth About Waste-To-Energy(by Marco J. Castaldi. PH.D.) This study provides the most up-to-date information on WTE and the environment, and can serve as a comprehensive resource for policy makers and others interested in learning more about the quantifiable benefits of WTE.

Summary: Scientific Truth About Waste-To-Energy.If you don’t have time for the full report, this high level 2 page summary will give you the key points.

Summary Table of WTE Benefits.  Another great resource on the high level summary of WTE benefits.

The Zero Waste Utopia and the Role of Waste-to-Energy. From the opening paragraph: While there is no doubt that the prevention of municipal solid waste (MSW) generation should sit at the top of any public policy, industrial strategy and individual behavior, just like reducing the consumption of energy, this proposition might mislead the public into thinking that waste can suddenly disappear if only we had the will to make it happen. Zero Waste seems to be the only accept-able aim for today’s politicians who embrace an environmentally friendly platform. As a result, countries and municipalities all over the globe have committed themselves to achieving the goal of Zero Waste. So far, however, nobody has managed it, and given the many scientific and practical roadblocks, no one ever will.

May 23: Forest Health and Climate Change Featuring Joey Hulbert

We had a discussion with Joey Hulbert who is a Research Fellow at WSU about how community scientists are accelerating research to create shared understanding of tree health issues in the Pacific Northwest as part of the Forest Health Watch program.  Western redcedar is an important and iconic tree to PNW communities and information is urgently needed to sustain it for future generations. While there is a general consensus the dieback is linked to longer and hotter droughts, the relationship is complex and it is unclear which environmental parameters and site characteristics are most important for determining where trees are vulnerable. Anyone can participate and contribute to advance knowledge as community scientists. More information is available at

May 9: Owning an Electric Vehicle

Our panel of owners talked about their experience of purchasing and owning an electric vehicle (EV)Watch to learn if it’s right for you.  We represented a variety of EV experience, including owners of the most common EVs, including a Tesla Model 3, a Chevy Bolt, a Nissan Leaf, and a BMW i3.  We also discussed the upcoming innovative solution from Tom Gurski, Founder of Bluedot Motorworks to retrofit existing cars and turn them into hybrid vehicles.

April 25: Update on the 2021 Washington State Legislative Session With a Focus on Climate

John Stafford gave an informative and engaging talk on the last scheduled day of the 2021 WA State Legislative Session (April 25th).  John provided an update on what was accomplished, particularly as it relates to climate change. John will also speak about legislation requiring the teaching of climate change in grades K-12, a topic he is passionate about.

April 11: Biochar as a Climate Change Solution

Featured speaker, Jeff Thiel, presented a compelling case to answer these questions: What if we could sequester 10% of our current greenhouse gas emissions while improving the health of our soils, making farmers more profitable, and making our crops more resilient? That’s the potential of biochar. With recent innovations in gasification technology, we can turn agricultural and forestry waste into a valuable soil amendment at large scales.

March 28: Is There an Answer to the Problems Waste Poses to Climate, Health & the Economy?

On March 28, featured speaker Philipp Schmidt-Pathmann helped us to gain an insight into the world of waste management with a focus on climate impact and the opportunities we have to significantly turn that around. He discussed  our regional and national roadblocks and how to overcome these based on examples from North America and Europe. Full Description at Meetup here.

March 14: Earth-friendly Investing with Peter Krull of Earth Equity Advisors 

On March 14, Featured speaker, Peter Krull discussed Sustainable, Responsible and Impact Investing (SRI) also known as socially responsible investing. Peter also covered the history of the strategy, current trends, and why it’s important to align your investments with your values. Other topics included were fossil fuel free investing, investment performance and what to look for in a SRI investment. There is Q&A session at the end from the questions that were asked throughout.
