Climate Papa
At the intersection of climate change, technology, and parenthood.
Climate Papa is a home for the climate dads, climate papas, and climate papis. The climate abbas, the climate babas, and climate tatas.
We're here to gather folks sitting at the intersection of Emily Oster, Dr. Volts, Jason Jacobs, and Elad Gil. Maybe I’m the only one. Maybe there’s dozens of us.

#16 - Introducing Stepchange, our new venture fund
As the first episode of the year, I’m focusing on a bit of a personal update. Today, I'm announcing the launch of a new climate venture fund, Stepchange. I use this week's episode to share the story behind the fund.
I struggled with putting this episode out—I felt self-conscious spending the time promoting my work so publicly. But I believe that investing our money, our time, and our social capital in these startups is the best thing that I can do right now to make a difference. These companies will be critical to our energy transition and to addressing big elements of the climate crisis. This is how I’m spending most of my time. This is my toolkit, my hammer—and I’m going to swing it.
So yes, this episode is me introducing Stepchange.
The episode plays out in three parts:
We review the Stepchange thesis on climate investing, discuss how the fund came to be, and chat with our venture partners: Anay and Arthur. We also meet three of our fund advisors: Steph, Ari, and Ian.
I interview founders from the fund’s first four investments: itselectric, Bayou Energy, Line.Build, and Rhizome.
I chat with fund collaborators and investors (LPs): Aaref from Bain Capital Ventures, Julie Sandler from PSL, and Marc Bridge.
Thanks so much for listening today. I'm really excited to get Stepchange out into the world. Here’s to 2024.

#15: Making the climate revolution irresistible with Nicole Kelner
See Nicole's work referenced here.
The world of climate tech is small and something happened about two years ago. From climate newsletters to Twitter accounts and LinkedIn posts... everything became more...colorful. There were stunning watercolors explaining the carbon cycle in oceans, the carbon impact of a hamburger, or the way that heat pump works to magically transfer heat into a home. Nicole Kelner had arrived on the scene. Taking her unique water color style and combining it with a deep desire to understand, and communicate, climate solutions.
In this conversation, Nicole shares her journey to climate tech artist, her process for coming up with new art ideas, and her love of running the business. We also cover why Taylor Swift should date a climate scientist, the role of AI in art, and how to make wind turbines into a beautiful neon mural.
Nicole's created the first climate solutions coloring book, The Electrify Everything Coloring book.
The next episode of Climate Papa will share more on my focus for 2024. If you haven’t already subscribe here to follow along.

#14: The urgency of this decade and YC's role in climate tech with David Rusenko
It was the summer of 2022 and David Rusenko had completed 15 years of a classic Silicon Valley success story. It started back in 2007 when he applied to the 4th batch of YC two hours before the deadline with his startup--Weebly. He grew Weebly, a website and ecommerce platform, to hundreds of employees and hundreds of millions in revenue and was acquired by Square in 2018. At Square he took on integrating Weebly and leading all of the growing company’s ecommerce products. When it came time for David to pop his head out to think about what was next he came to a familiar conclusion--he would deeply regret not spending this essential next decade working on climate.
This conversation was filled with an abundance of agreement on the urgency to work on climate, founder-company fit, and the values we want to bring to our work with founders. We talk about some of the areas most interesting to us and the underrated role that YC has played in bolstering the climate tech ecosystem.
As I've gotten to know David over the last few months, I've consistently found a kindred spirit--someone trying to take the last 15 years of product and company building and apply it to climate tech. Putting to use all the founder empathy muscles possible, and trying to dust off our electrical engineering backgrounds. We also love hearing our kids comment on the slow and smelliness of fossil fuel burning machines.
David invites climate tech founders that are raising their pre-seed or seed rounds to get in touch at leapforward.vc--and to maybe look for some fun easter eggs on his website.

A personal message on Israel
I wasn't sure if I should put an episode out this week. I feel like at any given moment nearly 100% of my mind and attention and definitely my emotional energy has been on processing the events over this last weekend in Israel.
Climate Papa is not a news podcast and certainly not a geopolitical podcast. But this is a personal podcast--it's been a space over the last few months where I've shared a lot about what I'm thinking about and processing. It's a bit of a window into my lens on the world. And this week I’ve been feeling a lot of pain. In this short message I share what I’m feeling and share a poem that struck me.The Diameter Of The Bomb by Yehuda Amichai (1976):
The diameter of the bomb was 30 centimetersand the diameter of its effective range about 7 meters,with four dead and 11 wounded.And around these, in a larger circleof pain and time, two hospitals are scatteredand one graveyard. But the young womanwho was buried in the city she came from,at a distance of more than a hundred kilometers,enlarges the circle considerably,and the solitary man mourning her deathat the distant shores of a country far across the seaincludes the entire world in the circle.And I won’t even mention the crying of orphansthat reaches up to the throne of God andbeyond, making a circle with no end and no God.
I will return to talking about climate change and technology shortly.
Love,Ben

#12: What can the Climate Movement Learn From the Jewish High Holidays?
Announcement: It’s PNW Climate Week next week and I’m going to host the first ever Climate Papa meetup! Next Wednesday, September 27th, at 3:30pm at Volunteer Park. Register here!
Fall is here—the leaves are changing and it’s back to school season. This time of year always feels like the “real” start to the year. Coincidentally, it’s when the Jewish High Holidays begin, the New Year, Rosh Hashanah, followed by Yom Kippur, and Sukkot. What does this have to do with climate change? Well, Jews have been on an annual rhythm of “repentance, prayer, and charity” for millennia. Perhaps the High Holidays have something to teach us about how to build a pattern of individual and collective assessment, reflection, and action?
Ben turns to Tamar, host of a climate Torah Study podcast, to get a High Holidays 101 lesson, and to help unpack the symbolism of the holidays in the context of a climate crisis. They reflect on how holidays can awaken our motivation, how disasters affect communities, and they compare the Book of Life to regular IPCC reports.
Tamar Libicki is a mother and fan of green energy, habitat restoration, regenerative agriculture, and Torah study. She hosts the "Ḥoni's Circle" podcast along with Rabbi Paula Rose, which is a project of Congregation Beth Shalom and Ahavat v'Avodat haAdamah.

#11: The Health Risks of Gas Stoves and the Future of Cooking with Weldon Kennedy
Well, we made it ten episodes in before hitting on the most emotionally charged of home appliances—the cooktop. Despite gas stoves not being a significant cause of emissions, they are a clever lock-in device used to drive homeowners to want to keep (or even add) gas hookups to their homes. The plan may ultimately backfire as we all become aware of how terrible it is for our (and especially our kids’) health to be combusting gas inside our homes. Fortunately, there’s a quiet, powerful, and clean alternative — induction cooking.
Ben chats with Weldon about the joyous exploration of 2-year-olds as they learn how the world works, including the toilet. They take the same curiosity to unpack the health concerns of burning methane gas in our homes and exploring why induction is going to be the ideal way for most of us to cook in the future.
They discuss how Weldon’s new company, Channing Street Copper, is solving the biggest barrier to induction adoption—removing all the complex electrical work. By adding energy storage (a big battery) to the stove it can work with a standard power outlet and even continue to work during power outages.
Ben and Weldon wrap up discussing the fundamental optimism needed to be a parent and that choosing to work on climate is just doubling down.
Weldon Kennedy is a Co-Founder and CMO of Channing Street Copper. He previously founded and scaled the first Kenya-native running shoe company, Enda, after serving as the Managing Director for Change.org Europe.

#10: The magic devices that cool (and heat) our homes and how to perfect them with Bill Kee
It's the middle of August. For most of us, this is a hot and humid time of year--especially with heat waves raging across much of the world. To deal with more extreme temperatures we're going to need effective cooling, and a lot of it, quickly. Fortunately, we have the right device that can suck heat out (or push it into) our homes — heat pumps.
Ben chats with Bill to get to the bottom of how heat pumps work their magic. They unpack how ductless systems make sense as the "platform of the future" for the ideal experience and why we're now at the product and UX optimization moment for heat pumps.
They talk about the work Bill is doing at Quilt to make this ideal product a reality and how Bill went from a product leader working on Gmail and ad analytics products to explaining heat pump phase changes.
Bill leads Quilt’s product and go-to-market efforts. Previously, he led teams developing energy efficiency technology for Google’s real estate footprint, and earlier worked on products like Gmail and Google Analytics. His family heats and cools their home with a ductless heat pump, and he’s passionate about building a much better product and adoption experience to help leave his two sons a more sustainable world.
