The Science, Risks, and Governance of Doing It On Purpose (Salon 10, Extended)
May 16, 2026 · 44 min · Kelly Erhart
We already change the climate every day, by accident and in the dirtiest way possible. At Metacrisis Salon #10 in Brooklyn, Kelly Erhart of Outlier Projects asked a New York living room the uncomfortable question: should we start doing it on purpose? The science, the risks, and the rules it would demand.

Full transcript
0:00 Gemini: The hardest question in climate isn't scientific. It's who gets to decide and by what right? I'm Gemini.
0:04 Gemino: And I'm Gemino.
0:06 Gemini: Dear crisis is a Brooklyn community that meets monthly to face the big crisis together. This is the long version of Meta Crisis Salon 10, the whole evening unhurried and a 20-minute version lives in the feed.
0:16 Gemino: Because, um, humanity is currently running the largest geo-engineering experiment in the history of the Earth, right? And we are doing it entirely by accident.
0:24 Gemini: Yeah, completely blindly. So tonight we are looking at the carbon pulse. We are looking at a conversation shaped by Kelly Earhart from Outlier Projects and event host Von Wong, to examine what happens when the biology of the planet just, well, stops behaving the way our spreadsheets predict it will.
0:38 Gemino: Right. And to grasp the reality of that geo-engineering experiment, you have to start by like completely discarding the way we usually talk about climate change.
0:45 Gemini: Which is usually as a policy debate, right?
0:46 Gemino: Exactly. A matter of taxes and regulations, um, emissions targets. But Von Wong opened this salon by forcing the room to look at the physical reality of the Anthropocene. The actual scars on the Earth.
1:02 Gemini: Yeah, he used the photography of Edward Bertinsky to do this. Which, if you haven't seen it, I mean it operates on a scale that almost breaks the human brain.
1:08 Gemino: It really does.
1:08 Gemini: Yeah. Because Bertinsky, he doesn't photograph like a single smoke stack or a sad polar bear. No, he photographs the industrial supply chain from the perspective of a satellite or like a low-flying aircraft. So you see palm oil plantations in Borneo that have entirely replaced the ancient rainforest.
1:23 Gemino: Right.
1:27 Gemini: But from above, they just look like this terrifying infinite fractal pattern of green monotony.
1:32 Gemino: Yeah, and you look at lithium evaporation flats in the Atacama Desert, and they are just industrial sites. They are these massive neon yellow and electric blue geometric pools carved into the Earth.
1:41 Gemini: It looks like the motherboard of a computer, but it's our planet.
1:43 Gemino: Exactly. It visualizes the sheer metabolic rate of modern humanity. Like when you see the petrochemical complexes in Baytown, Texan through that lens, they look like the internal organs of a planetary scale machine.
1:52 Gemini: And the reason starting with these images is so critical, I think, is that it eliminates the abstraction.
1:59 Gemino: Yeah.
1:59 Gemini: When we debate the quote-unquote energy transition, we act as though we are just swapping out a few lines of code in the global economy. But the visual evidence proves that we are physically terraforming the Earth's surface to sustain our current way of life.
2:12 Gemino: And terraforming always has a physical cost. So Von paired those static, silent images of industrial sprawl with a terrifying piece of motion.
2:21 Gemini: Oh, that clip.
2:22 Gemino: Yeah, the clip from Jeff Orlowski capturing the largest glacier calve event ever recorded. It is just a monolithic wall of ancient compressed ice, hundreds of feet high, just vibrating, fracturing, and then utterly collapsing into the ocean.
2:35 Gemini: It doesn't even look like ice melting, it looks like a mountain exploding.
2:40 Gemino: Right. The physics of a calving event like that are just staggering. Ice that has been stable for tens of thousands of years suddenly losing its structural integrity because the water underneath it has warmed by like a fraction of a degree.
2:47 Gemini: And the sound of it, you know, the sheer violent kinetic energy of it is a direct physical consequence of the quiet, sterile extraction processes happening in those Bertinsky photographs.
2:54 Gemino: Exactly. And Kelly Erhart noted that watching that ice shatter struck her with absolute awe, like the terrible, awesome power of natural systems when they finally break.
3:04 Gemini: Which transitions perfectly into how Kelly framed the timeline of this breakage. She told the story of a single photon, and I really want you to trace the physics of this narrative because it entirely changes how you understand fossil fuels.
3:15 Gemino: It really does.
3:19 Gemini: Imagine a photon leaves the sun, it travels across the vacuum of space at the speed of light, hits the Earth's atmosphere, and strikes a prehistoric fern. We are talking about the Carboniferous period, roughly 315 million years ago.
3:27 Gemino: And that time period is crucial to understand. The Carboniferous period was a completely unique era in the Earth's history. The planet was covered in these massive, swampy forests.
3:38 Gemini: Right.
3:42 Gemino: And here is the bizarre biological quirk of that era, right? Trees and ferns had evolved to produce lignin, which is the tough polymer that makes wood stiff and allows trees to grow tall.
3:46 Gemini: Okay.
3:46 Gemino: But the microorganisms, the fungi and the bacteria that could actually digest lignin hadn't evolved yet.
3:50 Gemini: Wait, so nothing could decompose the wood, the trees would die, fall over, and just pile up?
3:57 Gemino: Precisely. For tens of millions of years, organic matter just piled up in these massive swamps without rotting.
4:06 Gemini: Wow.
4:06 Gemino: So that photon from the sun was captured by the fern through photosynthesis, converting solar energy into chemical bonds.
4:12 Gemini: Oh.
4:12 Gemino: When the fern died, instead of decaying and releasing that carbon back into the atmosphere, it sank into the anaerobic depths of the swamp.
4:16 Gemini: Uh-huh.
4:16 Gemino: Over geological time scales, tectonic plates shifted. That layer of undecomposed organic matter was subducted, pushed deep down into the Earth's crust. Exactly. So you have millions of years of stored solar energy suddenly subjected to immense geothermal heat and the crushing pressure of millions of tons of rock above it.
4:36 Gemini: And that pressure just cooks the water and impurities out of the organic matter, right? Compressing those carbon bonds tighter and tighter until it becomes a dense lump of coal.
4:38 Gemino: Yes. It essentially becomes a geological battery. And it sits there in the dark. It sits there while the tectonic plates drift apart to form the continents as we know them today. It sits there while the dinosaurs rise and go extinct. It sits there through multiple ice ages, for 315 million years, that photon's energy is locked in a subterranean vault.
4:57 Gemini: Until like a fraction of a geological second ago, humanity develops heavy machinery. We strip away the topsoil, blast through the bedrock, and pull that lump of coal out of the earth.
5:09 Gemino: Right.
5:11 Gemini: We throw it into a pulverizer, inject it into a massive furnace and ignite it. The combustion breaks those ancient carbon bonds, releasing the heat. That heat boils water. The water turns to high pressure steam. The steam spins a massive turbine, and a generator converts that kinetic energy into an electrical current.
5:24 Gemino: And this is where Kelly's story reaches its devastating punch line.
5:29 Gemini: Right.
5:32 Gemino: Where does that electrical current go? It travels across a grid to power a server farm in a data center on a highway in Wisconsin. And the ultimate purpose of that 315 million year old stored energy.
5:37 Gemini: Yeah.
5:37 Gemino: It powers the cryptographic verification of a credit card transactions so you can buy a cup of coffee.
5:41 Gemini: We are spending a 315 million year old inheritance in a fraction of a second to buy a latte. It is mathematically absurd.
5:53 Gemino: It really is.
5:53 Gemini: And the exhaust from that transaction, the carbon dioxide released into the atmosphere, is the most diffuse, useless form of energy in the universe. We take highly concentrated ancient solar energy, use it for a microsecond of digital convenience, invent the waste product into the fragile membrane of our atmosphere.
6:09 Gemino: It fundamentally altered the biological chain of entropy. I mean, for four billion years, life on Earth was constrained by real-time energy flow.
6:13 Gemini: Right, like what you could eat, what sunlight you could absorb today.
6:17 Gemino: Exactly. You could only use the energy you could gather in the present moment.
6:20 Gemini: Yeah.
6:20 Gemino: Entropy, the natural decline of a system into disorder, was held at bay strictly by this real-time metabolism.
6:26 Gemini: But humanity basically figured out a cheat code.
6:26 Gemino: Exactly. We found a way to access the deep past. We figured out fire, which took roughly 10,000 years to scale as a tool.
6:34 Gemini: Right.
6:37 Gemino: Then we figured out industrial fossil fuels, which took barely 200 years to completely conquer the globe. We accessed a reservoir of millions of years of ancient sunlight and burned it in two centuries. And it has only been in the last 50 years that the collective human consciousness realized this cheat code has catastrophic consequences.
6:48 Gemini: 4 billion years of evolution to reach a steady state, 10,000 years of fire, 200 years of industrial explosion, and 50 years of sheer panic. The acceleration is what is so dizzying.
7:06 Gemino: Yeah. It's not just the amount of carbon we are moving, you know, it is the velocity at which we are moving it.
7:08 Gemini: And that rapid burning of ancient energy isn't just releasing emissions, it is actively changing how the planet responds, leading us directly into the framework Kelly introduced to map out where this experiment has actually left us today.
7:16 Gemino: Right, because the daily news cycle does not give you an accurate picture of this reality. You are bombarded with contradictory information.
7:22 Gemini: Totally. Monday's headline says, solar panel installations are breaking all historical records. Tuesday's headline says, ocean temperatures are so high that coral reefs are experiencing mass mortality.
7:32 Gemino: And you cannot synthesize those two realities without a proper framework. So Kelly provided one by mapping our climate progress onto a dashboard with three lights, green, yellow, and red.
7:44 Gemini: Let's start with the green light because it is an actual massive achievement. In 2023, the global investment in clean energy reached roughly 1.8 trillion dollars.
7:50 Gemino: Which is a staggering amount of capital allocation. To put it in perspective, that is more than double the amount invested in fossil fuels during the same year.
7:56 Gemini: Wait, double?
8:03 Gemino: Double. If you had told an energy analyst a decade ago that renewables would be out investing fossil fuels by a factor of two to one, they would have laughed you out of the room.
8:09 Gemini: Wow. It represents an industrial mobilization on a scale we haven't seen since the Second World War. We are talking about massive supply chains for lithium processing, the scaling of giga factories for battery production and the deployment of solar arrays that cover miles of terrain.
8:20 Gemino: The technology is matured, the cost curves have plummeted, and capital is flowing.
8:26 Gemini: But that green light immediately bleeds into the yellow light. And this is the part that energy economists usually try to gloss over, right?
8:30 Gemino: Yeah. Yeah, they do.
8:31 Gemini: The yellow light is flashing because this massive deployment of clean energy is not actually an energy transition, it is an energy addition.
8:37 Gemino: This is a critical distinction that completely changes the math. A transition implies substitution.
8:48 Gemini: Mm.
8:48 Gemino: It implies that for every gigawatt of solar power we add to the grid, we turn off a gigawatt of coal power.
8:51 Gemini: Right.
8:54 Gemino: But that is not what is happening globally. The demand for energy is growing so rapidly driven by the industrialization of developing nations, the electrification of transportation, and the massive ravenous power demands of artificial intelligence data centers, that we are simply building clean energy on top of the old system.
9:06 Gemini: So we are still using more coal globally than we ever have in human history. We are using more natural gas, more oil, more of everything. It's the Jevon's paradox on a planetary scale. The more efficient we get at producing energy, the more our systems expand to consume it.
9:22 Gemino: We haven't actually written the script for how you actively dismantle and phase out the fossil fuel infrastructure. We are just like hoping that eventually renewables will outpace demand growth and start eating into the fossil fuel share.
9:32 Gemini: But time is the one variable we cannot manipulate. Which brings the dashboard to the red light. And the red light is what fundamentally defined the entire salon in Brooklyn. The red light is the realization that the Earth systems themselves are now destabilizing on their own, independent of human emissions in the present year.
9:48 Gemino: We are blowing past the 1.5 degrees Celsius target of the Paris agreement. That is no longer a debatable forecast, you know, it is an observational reality.
9:53 Gemini: Yeah. The most credible trajectories now have us heading toward a 2.5 to 3 degrees Celsius world. And the terrifying part isn't just the raw temperature number, it is how the planet is physically responding to that heat. Kelly shared a data point regarding the Earth's reflectivity, its albedo, that is just profoundly unsettling.
10:12 Gemino: Right. So albedo is a measure of how much incoming solar radiation is bounced back into space without being absorbed as heat. A perfectly white surface, like fresh snow, has a high albedo.
10:17 Gemini: Okay.
10:22 Gemino: A dark surface, like open ocean water or asphalt, has a low albedo. Historically, the Earth has reflected about 30% of incoming sunlight. But over the last 25 years, precise satellite measurements have shown that this reflectivity has significantly declined.
10:35 Gemini: The planet is getting darker.
10:35 Gemino: Yes. And because it is darker, it is absorbing more heat. Specifically, Kelly noted that the Earth is absorbing about 1.7 watts per square meter more than it used to.
10:42 Gemini: Now, 1.7 watts per square meter sounds tiny. It sounds like a nightlight bulb spread over a dining room table.
10:46 Gemino: It does, but you have to multiply that across the entire surface area of the globe.
10:53 Gemini: When you do that math, the scale becomes incomprehensible.
10:57 Gemino: Yeah, the warming impact of that lost reflectivity over the past 25 years is equivalent to adding roughly 2,400 gigatons of carbon dioxide to the atmosphere.
11:03 Gemini: Okay. I want to stop and force us to visualize 2,400 gigatons, because the human brain is not built to comprehend numbers with that many zeros. One gigaton is a billion metric tons.
11:11 Gemino: Right.
11:15 Gemini: If you took every single ton of carbon dioxide that humanity has emitted since the invention of the steam engine in 1750, every coal train, every gas-powered car, every factory, every deforested jungle, and you added all of that historical pollution together, it roughly equals the warming impact of this albedo loss.
11:32 Gemino: That's staggering.
11:33 Gemini: The planet has essentially duplicated our entire historical carbon footprint entirely off the books, just by becoming slightly less reflective.
11:36 Gemino: This phenomenon is known as stealth warming.
11:37 Gemini: Uh-huh.
11:44 Gemino: And it is vital to dissect the physical mechanisms driving it. Why is the Earth getting darker?
11:46 Gemini: Right.
11:46 Gemino: There are three primary physical drivers, and they are all interacting. The first two are intuitive, the loss of reflective cloud cover and the melting of ice and snow.
11:49 Gemini: Right, if you melt the white sea ice in the Arctic, you expose the dark, deep ocean water underneath. The ice used to reflect the sun, now the water absorbs it, which warms the ocean, which melts more ice. It is a classic positive feedback loop. And cloud dynamics are similar. As the atmosphere warms, the types of clouds that form change, and we are losing some of the lower, thicker clouds that act as planetary sun shades.
12:12 Gemino: But the third driver of this stealth warming is the one that is deeply ironic and profoundly challenging from a policy perspective.
12:18 Gemini: Oh, yeah.
12:19 Gemino: We are cleaning up our air pollution.
12:25 Gemini: This is the part that feels like a trap.
12:25 Gemino: It really does. For decades, we have been pumping industrial aerosols, sulfates, soot, smog into the lower atmosphere. From a human health perspective, this is a nightmare.
12:34 Gemini: Yeah, it causes asthma, respiratory disease, and millions of premature deaths globally. So, logically and morally, we have passed regulations to scrub these pollutants from our smoke stacks and our exhaust pipes.
12:46 Gemino: Right. The International Maritime Organization recently mandated a massive reduction in the sulfur content of shipping fuels, which was a huge victory for air quality.
12:48 Gemini: But those aerosol particles were doing something else in the atmosphere, weren't they? They were acting as cloud condensation nuclei. Explain the physics of that. How does pollution make a cloud?
13:00 Gemino: Well, water vapor in the atmosphere cannot simply condense into a cloud droplet on its own. It needs a microscopic surface to grab onto. A piece of dust, sea salt or in this case, a tiny particle of sulfate pollution.
13:06 Gemini: Okay.
13:07 Gemino: When you inject massive amounts of industrial aerosols into the sky, you provide billions of tiny surfaces for water to condense on. This creates clouds that are composed of numerous, very small water droplets as opposed to fewer, larger droplets.
13:20 Gemini: And physics dictates that a cloud with many small droplets is significantly brighter and more reflective than a cloud of larger droplets. It's known as the Tome effect.
13:27 Gemino: Exactly. Our smog has been acting as a massive unintentional artificial sunshade. It has been masking the true warming impact of our greenhouse gas emissions for decades. As we successfully clean up the air to save human lungs, we are inadvertently pulling back that sunshade. We are letting the raw, unmasked power of our historical carbon emissions hit the planet all at once.
13:48 Gemini: So, we are caught in a double bind. If we keep the air dirty, millions die from respiratory failure. If we clean the air, the planet experiences a rapid violent spike in temperature.
14:01 Gemino: Right.
14:01 Gemini: And this begs a massive question about our forecasting. So, our models are missing this completely. Are we flying blind because our instruments are calibrated to a stable Holocene that no longer exists? We have the most powerful supercomputers in the world running these models. Are they broken?
14:18 Gemino: Well, they aren't broken, but they are bounded by assumptions. The data confirming this massive energy imbalance comes from Series.
14:21 Gemini: What's that?
14:21 Gemino: That stands for the clouds in the earth's radiant energy system. Which is a network of NASA satellite instruments that physically measure the solar radiation entering the top of the atmosphere and the heat radiation bouncing back out. It is empirical, observational data.
14:34 Gemini: And when you plot the actual observed data from Series on a graph against the predictions made by the standard climate models, the real-world observations sit way outside the cluster of model predictions. The models are underestimating the speed at which this energy imbalance is growing by roughly a factor of two.
14:54 Gemino: The discrepancy comes down to a concept called equilibrium climate sensitivity, or ECS. This is essentially a measure of how sensitive the earth's climate is to a doubling of carbon dioxide.
15:00 Gemini: Okay.
15:00 Gemino: For a long time, climate models presented a range of sensitivities. Some models predicted a lower temperature rise, these are the cold models. Other models incorporating more aggressive feedback loops predicted a higher temperature rise, the hot models.
15:16 Gemini: And for years the consensus was to aim for the middle of the pack, right? To average them out.
15:16 Gemino: Exactly. But the series data is forcing a reckoning. The low sensitivity models are completely failing to capture the current reality. The only models that are accurately tracking with the observed rapid heating of the ocean and the loss of albedo are the high sensitivity hot models.
15:28 Gemini: That is terrifying. It means the worst-case scenarios from a decade ago are becoming the baseline reality of today. It means we are navigating uncharted, highly volatile territory using maps that were calibrated for a past that simply does not exist anymore. If the planet is retaining heat at double the expected rate, that heat has to go somewhere.
15:51 Gemino: And roughly 90% of that excess heat is absorbed by the oceans. It acts as a massive thermal buffer.
15:52 Gemini: Yeah.
15:58 Gemino: But when you pump that much thermal energy into the ocean, it physically alters the geometry of the planet.
16:01 Gemini: Mm-hm.
16:01 Gemino: Which takes into the fuse.
16:01 Gemini: The Thwaites Glacier.
16:01 Gemino: Right.
16:05 Gemini: Thwaites is constantly referred to in the media as the doomsday glacier. And the scale of it warrants the title. It is roughly the size of Florida and it is the keystone holding together the West Antarctic ice sheet. Right now, as we speak, Thwaites is losing roughly 50 billion tons of ice every single year.
16:15 Gemino: 50 billion tons. Try to picture that volume of water migrating from a frozen continent into the global ocean basin year after year.
16:24 Gemini: It's unthinkable.
16:27 Gemino: If Thwaites collapses entirely, it contains enough ice to raise global sea levels by about 65 centimeters on its own. But because it acts as a cork holding back the rest of the West Antarctic ice sheet, its collapse could trigger up to two to three meters of global sea level rise over the coming centuries.
16:39 Gemini: We are talking about the complete redrawing of the World map. A two meter sea level rise doesn't just mean high tide gets a little higher. It means the permanent inundation of coastal megacities, the salinization of essential agricultural deltas, and the displacement of hundreds of millions of people. And a vast majority of those people live on less than $5 a day. They don't have the luxury of migrating inland or engineering complex sea walls, they will simply be washed out.
17:01 Gemino: To understand why Thwaites is so uniquely vulnerable, you have to understand the specific geophysics of a marine ice sheet. Thwaites is not a block of ice sitting high on a rocky plateau. It is a river of ice that flows off the continent and grounds itself deep on the sea floor, far below sea level.
17:18 Gemini: And the point where the ice leaves the bedrock and begins to float on the ocean is called the grounding line, right?
17:20 Gemino: Correct. And the geometry of the bedrock beneath Thwaites is its fatal flaw. It has what is called a retrograde slope. This means that as you move inland from the ocean, the bedrock actually slopes downward, getting deeper and deeper.
17:35 Gemini: Wait, so if the ocean water melts the ice at the grounding line causing the glacier to retreat inland, the new grounding line is now sitting in deeper water.
17:42 Gemino: Exactly. And because it is in deeper water, the column of ice facing the ocean is thicker. A thicker column of ice at the grounding line means more ice flows outward into the ocean. So the further it retreats, the faster it discharges ice.
17:53 Gemini: It is a runaway physical feedback loop known as marine ice sheet instability. Once the grounding line retreats past a certain ridge, physics dictates that it will accelerate uncontrollably, regardless of what the air temperature is doing.
18:03 Gemino: And Kelly shared a massive revelation from Brent Minshu, a glaciologist at Caltech working with the Red Glacier Initiative that clarifies exactly where we are in that process. He pointed out that atmospheric warming, the hot air caused by our carbon emissions was the trigger for this instability.
18:16 Gemini: Hm.
18:16 Gemino: But it is no longer the driver.
18:21 Gemini: The driver is water. Specifically, circumpolar deep water. Changes in wind patterns have pushed this relatively warm layer of deep ocean water up onto the continental shelf and directly underneath the belly of the glacier. This warm water is now penetrating deep between the ice and the bedrock.
18:32 Gemino: Yeah. It's acting as a lubricant. It is melting the base of the glacier, reducing the friction that holds the ice back and driving massive slippage.
18:43 Gemini: This mechanical reality completely upends the conventional political narrative of climate mitigation. We are constantly told that if we just reach net zero emissions, we stop the damage.
18:50 Gemino: Right.
18:54 Gemini: But if we magically halted all human emissions tomorrow morning, if we shut off every coal plant and grounded every airplane, Thwaites keeps melting, it keeps sliding.
18:56 Gemino: Because the thermal mass of the warm ocean water is already there, deep underneath the ice, operating according to the laws of fluid dynamics and thermodynamics.
19:06 Gemini: The fuse is already lit. And this is where the gap between scientific observation and institutional planning becomes incredibly dangerous. Let's look at the Intergovernmental Panel on Climate Change, the IPCC. Their reports are the gold standard. They are used by urban planners, defense departments and insurance companies globally to calculate risk. The IPCC models project roughly half a meter of sea level rise by the year 2100 under a 3 degree warming scenario.
19:30 Gemino: But glaciologists who study the actual physics of marine ice sheet fracture point out a massive logical flaw in those projections. The IPCC projections, because they are consensus documents that average out various models, implicitly assume that the rate of sea level rise will actually slow down under higher warming scenarios, which contradicts every physical observation we have.
19:44 Gemini: Oh, wow.
19:46 Gemino: Yeah, they struggle to model the non-linear catastrophic collapse mechanics of an ice cliff failing.
19:54 Gemini: So, when Brent Minshu and the researchers at Aret ignore the consensus models and just extrapolate forward from the actual observed data trends of the past 60 years, they arrive at a completely different number. They project a sea level rise of more than 1.25 meters by 2100.
20:10 Gemino: That is more than double the IPCC's estimate. And crucially, that 1.25 meters only accounts for the predictable linear parts of the equation, thermal expansion of the oceans and steady surface melting.
20:15 Gemini: Right.
20:18 Gemino: It does not account for a sudden non-linear collapse of the Thwaites grounding line, which would add meters more to that total.
20:27 Gemini: And this massive uncertainty gap isn't just an academic debate, it dictates how we spend trillions of dollars. We are currently watching the economics of inaction manifest as a kind of surreal reactive madness. Because we are terrified of the rise in water, we are planning massive infrastructure projects based on those conservative IPCC numbers.
20:40 Gemino: Like New York City, right? They're exploring a storm surge barrier that is estimated to cost $52 billion. Houston is planning a massive sea wall complex, affectionately known as the Ike Dyke for $50 billion. Jakarta, which is actively sinking, is building a sea wall for 40 billion.
20:53 Gemini: We are proposing spending hundreds of billions of dollars on downstream reactive adaptation. We are building massive concrete walls to try and manage the failure mode of planetary physics. And we are sizing the height of those walls based on projections that the raw data suggests are already obsolete. A $52 billion wall is useless if the water tops it by a meter.
21:10 Gemino: Exactly. And while we are willing to spend infinite amounts of money reacting to the symptom, we are ignoring the root cause.
21:16 Gemini: Cool.
21:16 Gemino: Kelly presented the alternative, the upstream approach being researched by the Aret Glacier Initiative.
21:23 Gemini: Okay.
21:23 Gemino: Their entire research program, which includes building highly accurate, physics-based sea level forecasting models and critically researching actual interventions to physically stabilize the glaciers, costs roughly $100 million.
21:30 Gemini: $100 million to research stabilizing the source. Versus hundreds of billions to build walls that might fail. And the physical intervention Aret is exploring is genuinely fascinating because it relies on mature, off-the-shelf technology. They're looking at using thermosyphons.
21:51 Gemino: Yes. I want to break down what a thermosyphon is, because it sounds like science fiction, but it's actually just plumbing. A thermosyphon is a passive heat pump that doesn't require electricity or moving parts. You essentially drill a bore hole down through the ice to the bedrock. You insert a long closed pipe and you fill it with a pressurized gas like carbon dioxide or ammonia.
22:08 Gemini: And the physics of it are incredibly elegant. The gas at the bottom of the pipe, deep down near the bedrock where the water is lubricating the glacier, absorbs the heat from that water and evaporates. Because hot gas is lighter, it rises up the pipe to the surface of the glacier.
22:24 Gemino: Right. And the surface of the Antarctic ice sheet is brutally cold. So when the gas reaches the top of the pipe, it hits that freezing surface temperature, dumps its heat into the atmosphere, condenses back into a liquid and falls back down the pipe via gravity to repeat the cycle.
22:35 Gemini: It acts as a massive thermal conduit, continuously sucking heat out from underneath the glacier and exhausting it into the frigid air above. It artificially accelerates what nature sometimes does on its own to re-freeze a glacier to its bed, locking it in place and stopping the slippage.
22:48 Gemino: Exactly.
22:48 Gemini: Wait, we are using off-the-shelf oil and gas tech to potentially re-freeze Antarctica. Why is this not front-page news every single day? You're telling me we can freeze a continent with PVC pipes and gas. This isn't theoretical, right? This technology exists.
23:01 Gemino: It is highly proven technology. It is the exact same mechanism used right now along the Trans Alaska pipeline. They install thousands of thermo siphon into the ground beneath the oil pipeline to keep the permafrost frozen so the pipeline wouldn't sink and rupture.
23:09 Gemini: Wow, so we have the technology, we just haven't scaled it to an ice sheet. And the cost estimate for this?
23:18 Gemino: If the research proves it's viable and won't cause unintended structural damage to the ice, the estimated cost to manufacture and deploy enough thermosiphons to lock the critical grounding lines of the West Antarctic ice sheet is roughly $8 billion.
23:27 Gemini: Let that math sink in. $8 billion for a planetary-scale intervention to stabilize the source of global sea level rise. Versus over $140 billion just for three cities to build localized storm barriers.
23:39 Gemino: It's wild. The geopolitical and logistical hurdles of deploying massive drilling rigs in Antarctica are immense, certainly. But the cost-benefit analysis is so skewed that it highlights a fundamental irrationality in our political economy. We treat the collapse of the earth's systems as an inevitable act of God that we must passively suffer and adapt to, rather than an engineering problem we can actively stabilize.
24:03 Gemini: And it is a fringe conversation because admitting we need thermosins in Antarctica requires admitting that our neat orderly spreadsheets of carbon accounting have failed.
24:09 Gemino: Right.
24:09 Gemini: We love the illusion of the ledger, we think, you know, if I emit one ton of carbon and I plant enough trees to offset one ton of carbon, the ledger is balanced. But the earth is not a spreadsheet, it is a highly reactive biological and chemical system.
24:21 Gemino: Which brings us to the most terrifying reality of all, warming induced emissions. The moment when the planet stops being a passive receptacle for our pollution and becomes a rogue emitter itself.
24:32 Gemini: Yeah. We have built all of our global climate policies on the assumption that the earth will remain a sink. We assume the oceans and the forests will continue to absorb a large chunk of the carbon we emit. But as the planet gets hotter, that dynamic is reversing.
24:42 Gemino: And to understand this, we first have to talk about super pollutants. We focus so much on carbon dioxide, but gases like methane and nitrous oxide are vastly more potent.
24:51 Gemini: Methane, for instance, traps roughly 80 times more heat than CO2 over a 20 year period. Nitrous oxide is nearly 300 times more potent. Together, these super pollutants are responsible for roughly half of the warming we are experiencing right now.
25:04 Gemino: Right. We know how to stop anthropogenic super pollutants, we know how to plug leaky natural gas wells and how to change agricultural feed to reduce cow methane.
25:10 Gemini: Yeah.
25:10 Gemino: But what happens when nature takes over the production line? This is warming induced emissions, or WIE.
25:16 Gemini: It is the ultimate vicious cycle. Take the Arctic permafrost. For thousands of years, dead plant and animal matter has been locked in deep freeze. But as the Arctic warms at four times the global average, that permafrost is thawing. The ice turns into massive, slumping thermokarst lakes.
25:29 Gemino: And at the bottom of those lakes, in the mud where there is no oxygen, ancient microorganisms wake up. Methanogens. These archaea start gorging on the newly thawed organic matter and the waste product of their metabolism is methane.
25:43 Gemini: The lakes literally start bubbling with methane gas, venting it straight into the atmosphere, the hotter it gets, the more it thaws, the more it bubbles, the hotter it gets.
25:51 Gemino: The same dynamic is happening in tropical wetlands, which are massive reservoirs of carbon. As they heat up, their biological respiration rates increase and they exhale vast amounts of methane. We are also seeing it with massive unprecedented wildfires in Canada and Siberia.
26:04 Gemini: Yeah. The heat and drought turn the forests into tinder. When they burn, they don't just dump millions of tons of carbon into the air. from the standard climate models used to set national emissions targets. So, our current emissions budgets are massively undersized if we aren't counting the planet's own feedback loops. It's like trying to balance a budget while ignoring a massive compounding shadow debt. Imagine a massive corporation desperately trying to balance its budget by cutting employee travel expenses and office supplies while completely ignoring a multi-billion dollar off-balance sheet toxic debt facility that is compounding daily.
26:53 Gemino: That is exactly what our global climate policy looks like right now, our mitigation plans, our carefully negotiated Paris agreement budgets. are massively undersized because they assume the earth is a static variable.
27:02 Gemini: But Spark climate solutions is an organization that is staring directly at this shadow debt. They are doing the grueling work of trying to get these warming induced emissions quantified and integrated into actual policy so we can accurately see the cliff edge we are approaching.
27:20 Gemino: And they are researching how we might actively intervene in these natural feedback loops. Can we alter water management in wetlands to suppress methanogenesis?
27:22 Gemini: Right. And they are even exploring the frontier of atmospheric methane removal. Taking methane out of the ambient air is incredibly difficult because it is so diffuse measured in parts per billion. But nature already has a cleanup mechanism. The atmosphere contains hydroxyl radicals, often referred to as OH radicals.
27:37 Gemino: The OH radical is essentially the detergent of the atmosphere. It's a highly reactive molecule that seeks out methane and oxidizes it, breaking it down into carbon dioxide and water vapor. This happens naturally, but Spark is researching whether we can safely and artificially enhance this process.
27:54 Gemini: Can we introduce catalysts, perhaps mimicking the way natural iron dust storms interact with sunlight and salt to accelerate the generation of OH radicals and scrub the methane out of the sky before it triggers further tipping points?
28:02 Gemino: So if you step back and look at the brutal picture Kelly Airhart painted in that room in Brooklyn, we have speth warming from the loss of our aerosol sunshade and melting ice. We have the physics of marine ice sheets guaranteeing meters of sea level rise regardless of our current emissions.
28:21 Gemini: Yeah.
28:21 Gemino: And we have the Earth itself exhaling super pollutants in a massive accelerating feedback loop.
28:26 Gemini: If mitigation cutting emissions and adaptation building sea walls aren't enough because the planet is now reacting on its own, what is the third option?
28:27 Gemino: It forces a logical conclusion. Cutting our emissions is absolutely essential, but it's no longer sufficient. Building taller sea walls is too expensive, too late, and physically impossible for most of the global population.
28:38 Gemini: We have to move into the taboo territory. We have to discuss the third pillar of climate response. Stabilization.
28:47 Gemino: Climate stabilization encompasses the research, the governance frameworks, and the actual technological deployment options designed to directly intervene and stabilize the destabilizing Earth systems. We are talking about treating the fever directly. And the most controversial, heavily debated area of stabilization research is sunlight reflection.
29:06 Gemini: The core logic is brutal but simple. If the Earth's energy imbalance is caused by too much heat being trapped by greenhouse gases, and we cannot scrub those gases out of the atmosphere fast enough to prevent systemic collapse, can we reduce the amount of heat entering the system in the first place? Can we turn down the sun?
29:16 Gemino: Right. And there are several theoretical pathways to achieve this. You can look at surface albedo modification, painting urban roofs white or deploying reflective materials over deserts. But the physics of that scale poorly, it it can cool a localized urban heat island, but it barely nudges the global energy budget.
29:35 Gemini: Then you have marine cloud brightening, which we touched on earlier with the Twomey effect. The idea here is to deploy fleets of autonomous ships that spray a fine mist of sea water into the lower atmosphere over the oceans. The salt crystals act as condensation nuclei, brightening the marine stratocumulus clouds and reflecting more sunlight.
29:52 Gemino: And this is actually moving from theory to practice. Researchers in Australia have been conducting localized field tests over the Great Barrier Reef to see if they can create enough localized shading to prevent mass coral bleaching during marine heat waves.
30:03 Gemini: The difficulty with marine cloud brightening on a planetary scale is that climate models disagree wildly often by an order of magnitude on how effective it would be globally. Furthermore, because you are altering weather patterns in specific regions, it could lead to highly uneven cooling and massive disruptions to global precipitation patterns. You might cool the oceans, but accidentally cause a drought in the Amazon.
30:25 Gemino: Which leads us to the most steady, the most promising in terms of even cooling and arguably the most terrifying option on the table. Stratospheric aerosol injection or SAI.
30:33 Gemini: SAI bypasses the lower atmosphere entirely. The concept involves using specialized high altitude aircraft to release reflective particles, typically sulfur dioxide deep into the stratosphere, roughly 20 kilometers above the earth's surface. Up there, the particles disperse globally and create a uniform, microscopic reflective shield that scatters a fraction of incoming sunlight back into space.
30:55 Gemino: And the reason SAI is taken so seriously by physicists is that nature has already run the experiment for us, repeatedly and effectively.
31:01 Gemini: Oh, yeah, Mount Pinatubo.
31:01 Gemino: It's exactly.
31:02 Gemini: Yeah.
31:02 Gemino: In June of 1991, Mount Pinatubo in the Philippines erupted. It was one of the largest volcanic events of the 20th century. The eruption was so violent that it punched straight through the troposphere and injected an estimated 20 million tons of sulfur dioxide directly into the stratosphere.
31:19 Gemini: Once there, the sulfur dioxide oxidized into sulfuric acid aerosols, high altitude winds spread these aerosols around the globe in a matter of weeks. And we watched the planetary thermostat drop, the global average temperature cooled by about half a degree Celsius.
31:29 Gemino: And that cooling effect lasted for roughly a year and a half before the aerosols eventually precipitated out of the stratosphere. Pinatubo provided the empirical foundation for SAI. We don't have to guess if injecting sulfur into the stratosphere cools the planet, we know it does, the physics are proven.
31:38 Gemini: But knowing that it cools the planet is not the same as knowing it is safe to do intentionally. The second and third order effects of continuous artificial SAI deployment are deeply complex and fraught with risk. If we alter the solar radiation hitting the equator, how does that affect the thermal gradients that drive global wind patterns?
31:58 Gemino: Right.
31:58 Gemini: Could it disrupt the Asian monsoon season, which over a billion people rely on for agricultural survival? How does continuous sulfur injection affect the recovery of the ozone layer?
32:05 Gemino: And then there is the geopolitical nightmare of termination shock.
32:12 Gemini: Hmm.
32:12 Gemino: If you build this artificial sunshade, but you continue to pump carbon into the atmosphere beneath it, you are just masking a growing monster. If the geopolitical system collapses or a war breaks out and you suddenly stop spraying the aerosols, the sunshade disappears in a matter of months.
32:25 Gemini: And all of that pent up unmasked warming hits the planet in the span of a decade, causing a rate of temperature change so violent that biological adaptation would be nearly impossible.
32:32 Gemino: Not to mention the governance issue. Who controls the thermostat? A single wealthy nation or even a determined billionaire could theoretically afford the few billion dollars a year it would take to deploy a fleet of SAI aircraft.
32:45 Gemini: Right. If India decides the heat is literally killing its population and unilaterally deploys SAI, and the following year, Pakistan suffers a historic drought, you have the immediate preconditions for a nuclear conflict.
32:56 Gemino: This terrifying calculus is exactly why organizations like Reflective, which Kelly discussed, are pushing heavily for funding. But they are explicitly not advocating for immediate deployment, they are advocating for transparent, internationally governed, rigorous scientific research.
33:11 Gemini: We need to build the observational tools and run the computational models to understand exactly what SAI would do before anyone is tempted to try it. But I know that for a lot of you listening, a deep instinctual apprehension is bubbling up right now.
33:21 Gemino: Oh, for sure.
33:22 Gemini: This sounds terrifying. Aren't we just playing God with the weather, we broke the planet with industrial technology, and now we think we can fix it by spraying acid into the stratosphere?
33:28 Gemino: It is the most natural human reaction to have. But this is where Kelly offered a counter argument that profoundly clarifies our moral position. We are already playing God, we are already engineering the planet.
33:43 Gemini: She said it plainly. We are already engineering the planet in the dirtiest, most inequitable, most uninformed way possible. Every time a coal plant fires up, every time a forest is clear cut, every time we lay down another square mile of asphalt, we are actively running an uncontrolled planetary scale geoengineering experiment.
33:58 Gemino: Right. We are aggressively altering the atmospheric chemistry, changing the pH of the oceans and destabilizing the global energy budget. The illusion is that in action preserves a pristine natural state. But there is no pristine natural state left to preserve.
34:12 Gemini: The choice before us is not between human intervention and natural harmony. The choice is between continuing to intervene recklessly, blindly and destructively as a byproduct of our economic engine, or attempting to intervene consciously with scientific rigor, monitoring and international governance.
34:27 Gemino: And Kelly's warning regarding the research of SAI is critical. The existential risk of a botched geoengineering attempt does not come from scientists carefully studying it in a lab or running small scale atmospheric tests. The massive species level risk comes from ignorance colliding with desperation.
34:40 Gemini: Imagine the political reality of the 2030s. If climate impacts accelerate non-linearly, if we see simultaneous multi-bread basket crop failures or wet bulb heat waves that kill hundreds of thousands of people in a matter of days, the political pressure on governments to just do something immediately will become absolute.
34:55 Gemino: If we haven't done the research, if we don't have decision grade evidence on what actually works and what will inertly destroy the monsoons, the chances of a panic unilateral government deploying SAI blindly in a desperate attempt to save their citizens skyrocket.
35:14 Gemini: We have to map this territory so we know exactly what not to do, just as much as we need to know what we can do.
35:16 Gemino: This realization that we are already neck deep in the mess and have to consciously technologically navigate our way out of it brings us to the philosophical core of the evening in Brooklyn. Kelly shifted the conversation from the hard data of gigatons and albedo to the invisible narratives that shape our response.
35:27 Gemini: Right. She talked about the moral boundary that has governed the environmental movement for decades. The narrative that geoengineering is taboo is based on moral hazard.
35:38 Gemino: Moral hazard is a term borrowed from insurance. In climate, it refers to the dick fear that if we even acknowledge the possibility of technological fixes like carbon removal or solar radiation management, it will relieve the pressure on society to do the hard work of stopping fossil fuel extraction.
35:52 Gemini: The fear is that fossil fuel executives will use the promise of a future sunshade as a license to keep drilling today, and it is a completely valid, historically justified fear. The fossil fuel industry has a documented history of weaponizing delay tactics.
36:07 Gemino: But Kelly traced the history of the environmental movement to demonstrate that this moral boundary is not fixed. It is a constantly moving line, and it only moves when the physical reality of the planet forces it to.
36:12 Gemini: If you look back to the early preservationist era of the environmental movement in the 1960s and 70s, the entire ethical framework was built around protecting pristine nature from human corruption. They were deeply skeptical of any massive industrial intervention. They fought early large scale renewable energy projects like hydro dams and massive wind farms because they marred the natural landscape.
36:29 Gemino: Industrial decarbonization was viewed with profound suspicion. But as the carbon accumulated, the physical reality forced a shift. In the 80s, 90s and 2000s, the climate mitigators took charge. The absolute singular moral focus became cutting greenhouse gas emissions at the source.
36:49 Gemini: And during this era, talking about adaptation was the ultimate taboo. If you suggested building sea walls or planning for managed retreat from the coastlines, you were accused of giving up, you were accused of a moral hazard that distracted from the urgent need to cut emissions.
36:59 Gemino: Eventually, the climate impacts became so severe and the rising waters so undeniable that institutions had to accept adaptation. The moral line shifted. Then the exact same cycle repeated with carbon dioxide removal CDR and methane abatement.
37:07 Gemini: Right. For years, scientists proposing machines to set carbon out of the air were dismissed as pedaling technotopian fantasies that distracted from cutting fossil fuels. It was only when the ITCC models mathematically proved that we had already drastically overshot our carbon budgets and that we could not hit the 1.5 degree target without massive negative emissions that CDR was grudgingly accepted as a necessary pillar of policy.
37:32 Gemino: Every single time the historical arc is identical. The scientific data points to a terrifying reality. The institutions experience profound discomfort and reject the data to protect their existing moral framework. The physical harm becomes undeniable. And finally, the moral framework is forcibly updated and the taboo tool is normalized.
37:51 Gemini: Kelly's argument is that climate stabilization, researching sunlight reflection and glacier thermoyphons is simply the next inevitable step on that historical line. Stabilization is the new taboo.
37:57 Gemino: But she argued that what humanity is undergoing right now is far deeper than just grudgingly adding a new tool to our climate policy toolbox. To explain this, she drew a distinction between a paradigm shift and an episteme shift.
38:10 Gemini: This is a profound philosophical distinction. A paradigm shift is a concept coined by the philosopher of science Thomas Kuhn. It describes a fast change our scientific understanding of the mechanics of the world.
38:22 Gemino: Right.
38:22 Gemini: Scientists notice anomalies that the current model cannot explain like the models failing to predict stealth warming, so they build a new model. The Copernican Revolution, the realization that the earth orbits the sun and not the other way around, was a paradigm shift.
38:34 Gemino: An episteme shift, on the other hand, is a concept developed by the philosopher Michelle Foucault. An episteme is the unconscious underlying structure of what counts as knowledge in a given historical era. It is the invisible framework that dictates what is even conceptually possible for a society to think. It takes generations to shift.
38:48 Gemini: While Copernicus shifted the astronomical paradigm in his lifetime, the broader episteme shift, the enlightenment, the move from theological authority toward reason, empiricism and humanism, spearheaded by thinkers like Descartes, took centuries to fully penetrate the culture.
38:59 Gemino: The science of climate stabilization, understanding Earth's energy imbalance, tipping points and marine ice sheet mechanics. That is the paradigm shift. The scientific community is already undergoing it. But the deeper
39:12 Gemini: much more painful move is the episteme shift.
39:12 Humanity is being forced to fundamentally change how it views its relationship to the planet.
39:15 Gemino: For centuries, our episteme has been built on the illusion of separation.
39:18 We viewed humanity as the protagonist and nature as a static backdrop. Nature was either a resource warehouse to be extracted for our economic growth, or it was a pristine museum to be cordoned off and preserved.
39:30 Gemini: Even our climate accounting systems were built on this illusion assuming a linear balanced equation where we control the inputs and the earth passively absorbs the outputs.
39:37 Gemino: But the new episteme demands that we recognize we are embedded inside a highly reactive system of systems.
39:42 Humanity must move from seeing itself as separate from Earth to being embedded inside a system of systems. We are not separate from the Earth, we are an active, highly consequential component of its biology and chemistry.
39:52 Gemini: We cannot preserve the planet because we have already fundamentally altered its operating system.
39:57 We have to move from the illusion of mastery and control to the humbling reality of destabilization management. We have to take responsibility for the incredible power we are already wielding.
40:10 Gemino: Accepting that requires a profound psychological update.
40:16 It is the terrifying loss of innocence. It requires us to become wise ancestors and take responsibility for our power. And this is where Kelly brought in the perspective of the writer Rebecca Solnit to address the emotional toll of looking directly at this data.
40:25 Gemini: When you understand the physics of Thwaites or the scale of stealth warming,
40:33 it is incredibly easy to fall into despair.
40:33 Gemino: Kelly explicitly rejected both extremes of the current cultural reaction to the climate crisis.
40:37 On one side, you have the trap of blind hope. This often takes the form of techno-optimism, the assumption that AI will fix it, or some magical future technology will just invent a machine to fix the atmosphere.
40:45 Gemini: Or it takes the form of degrowth utopianism.
40:49 The belief that we can simply convince eight billion people to smoothly transition back to a localized agrarian lifestyle. And that carbon pulse will just naturally recede. Both forms of blind hope are a refusal to engage with the messy physical reality of the damage already done.
41:02 Gemino: On the other side of the spectrum, you have left despair.
41:05 This is the cynical belief that the capitalist system is too entrenched, the tipping points are already crossed, the situation is catastrophically irredeemable, and therefore there is absolutely nothing we can do. Despair is ultimately just another form of apathy, it relieves you of the burden of action.
41:15 Gemini: Neither blind hope nor left despair allows us to engage honestly.
41:22 Kelly said something that I think everyone in that room in Brooklyn felt resonate in their chest. She looked at the audience and said, it's not the canvas we wanted, we don't have the world we wanted, we're not going to.
41:32 Gemino: It is a moment of profound, necessary grief to accept that statement.
41:32 The stable Holocene epoch, the climate that birth human civilization, agriculture, and every city we have ever built is gone. We cannot legislate it back into existence.
41:46 Gemini: But on the other side of that grief is a fierce, pragmatic demand for action.
41:51 Because, as she continued, while we won't get the world we wanted, there is still an enormous consequential amount of space to decrease suffering and increase thriving. Every fraction of a degree matters, every millimeter of sea level rise delayed matters.
42:03 Gemino: That is the honest middle path.
42:03 We have to embrace the episteme shift. We have to look at our coastal cities, built for a stable ocean that no longer exists, and radically redesign them. We have to look at our agricultural systems, built for predictable rainfall and re-engineer them. The episteme shift means every single person, not just climate scientists, but urban planners, supply chain managers, artists, voters, has to update their worldview in time for it to matter.
42:22 Gemini: Oh, you could actually see that episteme shift happening in real time in that room in Brooklyn.
42:26 The organizers of the Deer Crisis Salon ran live polling with the attendees throughout the three hours of the event. They asked the audience to rate their feelings about geo-engineering and stabilization research on a scale from negative five to positive five.
42:36 Gemino: Before the salon began, before Von Wong showed the Bertinsky images and before Kelly told the Photon story, the average sentiment was deeply skeptical.
42:43 When asked what words came to mind regarding geo-engineering, the responses were exactly what the old moral hazard framework would predict: human hubris, GMOs, dangerous techno quick fix, playing God with the weather.
42:55 Gemini: But then, they sat together for three hours.
43:01 They didn't listen to a sterilized corporate sales pitch. They listened to the harrowing, unvarnished physical reality of the carbon pulse. They looked at the satellite data on stealth warming. They learned about the retrograde slope of the Thwaites Glacier. They confronted the philosophical shift required to take responsibility for our planetary impact.
43:13 Gemino: By the end of three hours, after all the data had been laid out and the dialogue had run its course, the prevailing words completely shifted.
43:23 Gemini: Instead of hubris and technofix, the prevailing words on the screen were hope, opportunity, a chance to change our trajectory and more research and honest dialogue.
43:26 Gemino: It was a visceral, empirical demonstration of a profound truth.
43:33 When people are trusted with the complex, terrifying reality of our situation, they don't inevitably default to despair. The room shifted from skepticism to a deep realization that honest dialogue is better than ignorance.
43:47 Gemini: That shift in the room, from skepticism to a demand for responsible clear-eyed action, is what the episteme shift looks like in practice.
43:55 It's recognizing our power, dropping the illusions of control, and figuring out how to survive together in the world we've actually made.
43:55 Gemino: We want you to be part of that conversation.
43:58 Find us at dearcrisis.com. I'm Gemino.
43:59 Gemini: And I'm Gemini.
44:05 Gemino: See you in November.
