Pronuclear Advocates & Allies

About the Pronuclear Climate Movement

Pronuclear climate advocacy has been around for only about a decade but it has grown rapidly. It consists mostly of young people who understand the urgency of the climate crisis and recognize that nuclear energy is a way to help us transition away from fossil fuels. They believe we should protect existing nuclear plants providing large amounts of clean energy and build more.  They have worked to save plants slated for premature closure, like Diablo Canyon in California and Palisades in Michigan. And they continue to work to save existing nuclear plants around the world, reform clean energy policies that exclude nuclear and favor renewables and educate the public about the benefits of nuclear. This is a reflection of growing support for nuclear power in general and a recognition that the goal of the climate movement is to prioritize retirenent of fossil fuel plants—whose massive volume of waste emissions is forcing the warming of our planet—not shut nuclear, whose waste hurts no one and is actually a valuable future energy resource.

The pronuclear movement consists of mostly smaller, independent groups that do grassroots organizing around a theme, such as working to prevent the closure of a local nuclear power plant. Fortunately, many of these groups are interconnected yielding suprisingly effective coordination when it matters. Many also have broader goals, such as the Climate Coalition, which aims to strengthen the climate movement overall by uniting climate activists of all stripes in support of an "all-of-the-above" nuclear-inclusive approach to clean energy. These groups can use your help.

How to Support the Pronuclear Climate Movement

For those who want to support nuclear power in addition to (or in lieu of) investing in next-generation technologies through Nucleation Capital, we provide the following recommendations:

  1. Take Action in Support of Nuclear Power: We have launched a Pronuclear Advocacy Actions page. Please check this page to learn about ways that you can support pronuclear actions. If you are organizing an action in support or nuclear or know of one, please submit the information to add it to our action page.
  2. Stop Supporting Anti-Nuclear Organization: Stop sending donations to the Sierra Club, NRDC, 350.org, Friends of the Earth, League of Conservation Voters, or Greenpeace. These large NGOs remain staunchly anti-nuclear and that is primarily what is dividing the climate movement.
  3. Urge your NGO to Prioritize Climate: If you have been a member or supporter of an anti-nuclear environmental group, let them know you don't support their anti-nuclear positions—which are contrary to their supposed efforts to solve climate—and won't support them until they acknowledge the value of nuclear energy for combating carbon emissions.
  4. Actively Support Pronuclear Groups:  Throw your support behind one or more of the pronuclear nonprofits that are working hard to save existing power plants and to advocate for nuclear power. We have curated the following lists to help you find organizations or individuals to support.

Nucleation's Top 5 Pronuclear Organizations

1. CALIFORNIANS FOR GREEN NUCLEAR POWER

Californians for Green Nuclear Power, led by Dr. Gene Nelson, has  been a driving force for political accountability and responsible energy decision-making in California. Shedding light on sweetheart backroom political deals being cut by Governor Jerry Brown that were contrary to the public interest, CGNP filed suits and/or petitioned to become a party to CPUC and FERC proceedings. CGNP's work as an intervenor has been instrumental in helping to save Diablo Canyon. CGNP's in depth research continues to pose obstacles to efforts to overturn the California legislature's extension approval are being filed. (Donations can be mailed to CGNP at 1375 East Grand Ave Ste 103 #523, Arroyo Grande, CA 93420-2421.)

2. MOTHERS FOR NUCLEAR

Mothers for Nuclear was created on Earth Day 2016 by the power team of San Luis Obispo-based Heather Hoff and Kristin Zaitz, two moms to better represent the voices of women and mothers in support of Diablo Canyon and nuclear energy in general. Coordination with Californians for Green Nuclear Power, Save Clean Energy and many other groups enabled Governor Newsom to respond to strong public pressure to save Diablo Canyon when appealing to the California Legislature. Progressive women remain predominantly opposed to nuclear power, but Mothers for Nuclear have begun to rebuild the social norm of women being pronuclear. (Donations can be made online. EIN: 81-3349003)

3. GENERATION ATOMIC

Generation Atomic was created by Eric Meyers to represent the voices of younger generations and empower them to express support for nuclear in every type of venue and forum where discussions of how solve climate change is happening. The group creates fun, engaging, public actions in an effort to safeguard our future by championing the cause for nuclear energy. Not only do they use research, communication and relationship-building to advocate for nuclear, their actions typically involve dancing, singing, inflatable costumes and humor to inspire, empower and engage youth and defang anti-nuclear wrath. Operatic nuclear arias, anyone? (Donations can be made online. EIN: 81-4500446)

4. THORIUM ENERGY ALLIANCE

Thorium Energy Alliance was started in 2006 by John Kutsch to bring together scientists and energy experts who believe that thorium should be recognized as a high-value nuclear fuel and not treated as waste. Thorium is far more abundant and less radioactive than uranium, yet was rejected early on in the development of nuclear fuel. This despite evidence that the use of thorium is feasible and can be highly cost-effective. TEA works to raise awareness about thorium and hosts conferences, posts videos and serves as a central organizing and educational entity for many nuclear advocates, which history was beautifully captured in the Frankie Fenton documentary film "Atomic Hope." (Donations of cash or cars can be made online.)

5. CLIMATE COALITION

Climate Coalition was founded in 2016 by Valerie Gardner and a group of technology-oriented climate activists who recognized how much stronger the climate movement would be if climate advocates were not fighting amongst themselves. Climate Coalition works to build unity between climate activists who support renewables and those that support nuclear, who are often ardently in opposition to each other. This internecine conflict is why global effort to transition to 100% clean energy systems are delayed everywhere. Join Climate Coalition to show your support of unity against carbon emissions. (Climate Coalition is looking for a new leader to take this group to the next level.)

Gratitude in Greens and Blues

Understanding Biotic Regulation

The challenge of addressing climate change is extremely complex. Even reducing emissions from energy use—as deploying more nuclear will help us to do—doesn't ensure climate stability for future generations. Fortunately, there are things we can do now to better protect our current and future climate and, in appreciation of our investors, advisors and supporters, we are donating to a group whose insights around "biotic regulation" can make a big difference in how humanity fares.

It turns out that forests play a critical and pro-active role in climate change dynamics. Forests, and especially old-growth rainforests, can help to reduce the impacts of our planet's warming. The mounting levels of CO2 in the atmosphere are adding tremendous amounts of heat forcing: that is certain. What is less certain is how severely we'll feel those impacts. With healthy forests, we're much better off.

Emerging from the work of a group of atmospheric physicists, ecophysiologists, and biologists, is an awareness that, weather is not uniform and extreme weather events aren't being distributed equally. Forests, rather than being simply passive stores of carbon, are active participants in controlling weather, particularly the wind and hydrologic cycles. This means, where there are forests, the weather will be more regular, more temperature controlled and more normal.

How do trees and forests do this? They leverage physics, chemistry and their own biology to regulate weather. Through spreading canopies and networks of roots, trees collaborate in keeping the land cool and moist. This cooler air can generate cloud cover, which in turn generates rain and limits the penetration of sunlight, limiting heating impacts and droughts.

Trees can also use their ability to transpire—release moisture from leaves—to help increase the level of humidity in their vicinity, which can increase the air's moisture content and actually hasten rainfall. Clouds in turn reflect the sun's radiation back out into space, reducing heating in their areas despite the higher concentrations of CO2.

Forests, we have learned, have evolved on the planet for millions of years and they have adapted by being able to moderate their own climate. Trees use a number of physical mechanisms—rising warm air, denser cool air and the effects of condensation, to influence winds to suck moist dense cooler air from the seas onto the land and blow warmer air out to sea. Forests are not passive plants: rather, they can act as a massive biologic organism that can actually impact the physics in their environment to trigger rain. Not only is this good for them—giving them the fresh water they need—it is also vital to humanity.

Dr. Anastassia Makarieva, author of the Biotic Regulation substack, frequently discusses this complex blend of physical, chemical and biologic forces that form what she describes as a "biotic pump" that moves water from the ocean to the land. She has argued persuasively that forests play an active role. Further, that thinking that the primary value of forests is in their use as a store of carbon, is failing to recognize their vital function as a force that literally drives a large portion of the hydrological cycles of the planet.  Dr. Makarieva’s writing helps readers recognize the problem of focusing climate efforts exclusively on the issue of carbon emissions and not paying attention to the proactive role of forests as a moderator of extreme weather and protecting them . . . from being actively leveled.

As important as nuclear power is to humanity's ability to reduce emissions, preserving forests is equally important as a way to better prevent extreme heating effects from causing damange to vital ecosystems and human systems. Protecting our natural forests and especially rainforests is key to lengthening the runway for maintaining cooler temperatures and ensuring there is continued rain—even as emissions drive higher global temperatures. Therefore, in addition to our usual year-end support of non-profit groups protecting our nuclear power assets (blue), this year we are donating to the Biotic Pump Greening Group (green), which is working to increase our understanding of the role that forests play in protecting their own ecosystems.

Other Groups Working to Protect Rainforests

1. Restore established by Michael Kellett, which collaborated with the Biotic Pump team on organizing an "Embracing Nature's Complexity" conference in Munich in 2024.

2. Mongabay founded by Rhett Ayers Butler, one of the leading providers of ecological journalism, reporting on the state of forests, the often nefarious destruction being wrought on rainforests by corporations and the efforts and challenges of those who seek to protect them. Mongabay was the first big environmental news outlet that covered the biotic pump story, initially back in 2012, with more recent follow ups.

3. Amazon Watch, a 30-year old 501(c) organization, works together with and in support of the Amazon's Indigenous Peoples and allies calling for the Amazon to be free of oil, gas, mining, and all extraction and for the U.N. and Amazonian governments to protect the Amazon from deforestation for palm production or other destructive activities.

 


Groups We Support Working to Protect Nuclear

1. Mothers for Nuclear: Was started on Earth Day in 2016 by two moms who want to protect their children’s future on this planet. They were initially skeptical of nuclear, but through many years of questioning and working at California’s last remaining nuclear plant, they gradually changed their minds. Now they support nuclear as our largest and most hopeful source of clean energy, vital to addressing some of our world’s biggest challenges: climate change, air pollution, and energy poverty. Now, we have an organized way to share our stories and begin a dialogue with others who want to protect nature for future generations.

2. Stand Up for Nuclear: Works to advance nuclear energy worldwide by activating leaders, driving action, and fostering informed public engagement. Since 2019, Stand Up for Nuclear has grown the international movement, uniting citizens and organizations to champion nuclear energy as a key to securing our clean, abundant energy future. They strive to create a future where nuclear energy is embraced as a reliable and sustainable solution for a low-carbon world.

3. Californians for Green Nuclear Power: Is dedicated to promoting the peaceful use of safe, carbon-free nuclear power, and to keeping Diablo Canyon Nuclear Power Plant open, so it can continue in its important role of generating clean energy for the benefit of California’s economy.

Climate anomalies, ecologic disasters and climate uncertainties: All point to climate being worse than projected

Forest fires

Climate tipping effects may be kicking in

Forest loss graphFor those tracking the state of the climate, the report published by the BBC showing that tropical forests were being destroyed at the fastest recorded rate over the last year, was frightening, with the prospect of total forest dieback and "savannisation" of these areas is a growing risk.

Compounding the loss of old-growth tropical forests in 2024 (estimated to have covered an area as large as Ireland) and the release of their carbon stores, is the loss of the moisture and climate systems maintained by those forest ecosystems, which previously provided localized cooling effects, produced cloud cover and contributed to the atmospheric moisture necessary for rain. These had also helped to brighten the earth, thereby reflecting more of the sunlight that otherwise would cause heating. This moisture and water cycle activity gets destroyed along with the trees, plants and animal life. This climatic loss to broad areas may be having more of a negative feedback effective on the planet's overall warming than has previously been recognized.

Hansen chart 1

Global Surface Temperature Change (published 2/3/25)

This news add yet more data to the alarming report published in February by Dr. James Hansen, Dr. Pushker Kharecha and a team of sixteen other climate scientists plainly titled "Global Warming Has Accelerated: Are the United Nations and the Public Well-Informed?  In it, Dr. Hansen's team explains that global temperatures have leaped up more than a half degree (0.7°F or 0.4°C) over the last 2 years, with a total average temperature rise of +1.6°C relative to the temperature at the beginning of last century (the 1880-1920 average). This reflects a temperature rise over the +1.5°C (or 2.7°F) level that we set as our goal for maximum increase. As of the last year, we've already exceeded that level.

These increases have, according to Hansen, baffled Earth scientists, as the increase's magnitude was literally off the charts. There were multiple explanations presented as to what could have caused such a big increase. Declining aerosol pollution was seen as a key contributor, by reducing nuclei that aided cloud formation and thus reflection of sunlight, thereby effectively darkening earth and allowing more heat to be absorbed. These are very troubling and portentious changes that may, in fact, show that feedback effects are already accelerating the heating impacts of our CO2 emissions, such that they no longer follow a direct relationship.

Dr. Hansen's report received considerable criticism both because it departed scientifically from the mainstream's more conservative consensus of a lower rate of warming and climate "sensitivity," as determined by the IPCC, and because it called for "a complement to the IPCC approach" to "avoid handing young people a dire situation that is out of their control." In a response to some of that criticism, Drs. Hansen and Karecha decried the ad hoc opinions, ad hominem attacks and sense that the media has gravitated towards reporting the opinions of just a small handful of scientists, rather than covering the total community and range of analyses, including their own.

Dr. Anatassia Makarieva, an atmospheric physicist, responded to this debate with a substack post titled "On the scientific essense of Dr. James Hansen's recent appeal." In it she agreed with Drs. Hansen and Karecha that many scientists were understating the degree of climate forcing but also shared her sense that many of the climate models in use, including Dr. Hansen's, erroneously ignored the major role of the biosphere in the climate destabilization that we are now experiencing. Which may, she argued, partially explain why none of the models predicted the heat anomaly of the 2023 - 2024 time period. Dr. Makarieva writes:

Why is this [i.e. accurate climate models] so important? Unless external causes of this recent temperature anomaly are identified, we may be dealing with a self-reinforcing process — for example, of reduced cloud cover causing more warming, this warming causing even less clouds and so forth until something truly ugly happens to our planet. But, if so, such a process could be started by many factors and does not necessarily need CO2 to kick off. For example, deforestation-induced reduction of evapotranspiration in the Amazon is associated with extreme heat events. This alone could trigger the warming that could then self-amplify via cloud (or some other) feedbacks.

Climate modelsWhether or not we have permanent self-reinforcing amplification happening with the climate now is being debated, partially thanks to new voices like Dr. Makarieva's, entering the field. What is clear, however, is that the fewer clouds, aerosols, snow cover, sea ice and also more invisible sources of water vapor (such produced by  tropical forests and other natural ecosystems) the darker the earth is and the more sunlight gets through and heats the ground, the oceans and the air. This heating further impacts existing vegetation, ice sheets, permafrost and bodies of water negatively, which then also contribute more CO2, more fires, and further darkening of earth's surface. Earth's climate has been in a state of equilibrium for eons. Given what is happening with the climate now, it appears that it is leaving that state of equilibrium.

According to some reports, the Earth has "dimmed" by 0.5% in the past 25 years.  We've known this and scientists have been able to track decreases in sea ice at the poles, a major factor in global warming. We're now seeing the climate effects of reductions in aerosols (due to the shipping industry trying to clean up their act and emit less aerosols), and we're seeing reduced cloud cover.  The bottom line is that even just looking at cloud feedbacks, the more the climate warms, the fewer the clouds. The fewer the clouds, the more the planet warms. This feedback loop is enough to take us into very dangerous territory.  Which is yet another reason why we want to prevent the loss of tropical forests, not just because of the CO2 impacts but because of the cloud and water vapor impacts. This feedback loop could explain why the rate of heating of the planet has increased beyond what was expected, even by scientists like Zeke Hausfather and James Hansen.

Dr. Hansen continues to urge immediate action and has proposed that "a multitude of actions are required within less than a decade to reduce and even reverse Earth’s energy imbalance for the sake of minimizing the enormous ongoing geoengineering of the planet; specifically, we will need to cool the planet to avoid consequences for young people that all people would find unconscionable."

If we agree that it is a promising prospect, you can offer to help them raise capital through our pronuclear investor network and syndicate. If they like that idea and agree to give us an allocation of equity, you will then produce a deal memo and we will float a syndicate to help them raise capital.

When investors agree to participate in the syndicate, they pay no management fee but they agree to pay carried interest to the deal sponsor, which is Nucleation Capital. Depending upon your contribution to creating the deal memo and promoting the SPV, we will provide a fair split of the carried interest fee earned from the successful exit of this venture.

There are two ways that you can work with us to bring us potential deals and earn participation on the success of the ventures you bring:

1. Venture Associate: If you are a young professional keen to learn how to help ventures raise capital with some spare time to devote to meeting new teams and making introductions, we will bring you on as a Venture Associate.  You'll get training, guidance on how to find and connect with new ventures, and invitations to participate in due diligence sessions as well as other opportunities to enage with our syndicate team. We'll help you build your skills in this area and show you how to evaluate new ventures.

2. Ventury Ally: Perhaps you are a bit too busy to take on the task of writing deal memos but you are well connected, want to help worthy ventures raise capital and would like to make introductions. We invite you to join our team as a Venture Ally and we will delegate syndicate prep tasks to another member of our team. We would welcome your help connecting us to new teams working in our sectors through simple introductions.

This is an incredible opportunity for those keen to learn the ins and outs of the venture capital industry and for those who are deeply connected into the start-up world to help to help build stronger ventures.
