Record #SolarSuperstorm shrank Earth’s plasma shield 78%, #GPS at risk
Story by Alexander Clark, 12/1/2025
Excerpt: "Why this storm is a warning shot for the #SatelliteEconomy
"Even without a total collapse of the magnetosphere, the recent superstorm delivered a clear warning to the satellite industry. Constellations in low Earth orbit [#LEO], such as #SpaceX’s #Starlink or #OneWeb, already have to contend with atmospheric drag and radiation, but they usually operate well inside the magnetosphere’s protection. When the plasma shield shrinks, those satellites face a double challenge: increased drag from a heated upper atmosphere and a more hostile radiation environment that can degrade electronics and solar panels. The event that compressed Earth’s shield by nearly 80 percent effectively stress-tested the assumptions behind the rapid expansion of commercial space infrastructure, a point underscored in analyses of how a solar storm can threaten satellites when the magnetosphere is squeezed.
"For operators of navigation, communications, and Earth observation satellites in higher orbits, the implications are even more direct. Many of these spacecraft were designed based on historical records of geomagnetic storms that did not include such extreme compression of the magnetosphere, which means their shielding, redundancy, and fault management systems may not fully account for the conditions seen in this event. As I look at the trajectory of the satellite economy, with thousands of new platforms planned for launch in the coming years, the lesson is clear: space weather resilience can no longer be treated as a niche concern. It has to be built into hardware design, constellation architecture, and operational playbooks from the start, or the next superstorm could turn a profitable orbital network into a liability overnight.
"Preparing for the next superstorm in a crowded sky
"The recent compression of Earth’s plasma shield did not trigger the kind of global blackout or navigation collapse that worst-case scenarios envision, but it came close enough to expose the seams in current preparedness. Space weather forecasting has improved, yet the lead times and confidence levels are still limited, especially for the most extreme events. To protect GPS, power grids, and other critical systems, operators need not just alerts that a storm is coming but actionable guidance on how severe the magnetospheric compression is likely to be, which orbits will be most exposed, and how long the elevated risk will last, insights that depend on the kind of multi-satellite observations and modeling showcased in the reconstruction of this storm.
"As I weigh the evidence, the path forward looks less like a single technological fix and more like a layered strategy. That means hardening satellites and ground infrastructure against radiation and induced currents, building redundancy into navigation and timing systems so that GPS is not a single point of failure, and integrating space weather scenarios into everything from grid planning to aviation routing. It also means improving public communication so that when the next superstorm hits, people understand both the seriousness of a 78 percent shrinkage of Earth’s plasma shield and the practical steps being taken to manage the risk. The recent event was a vivid reminder that our digital civilization is built inside a magnetic cocoon that can flex and falter, and that planning for those moments is no longer optional."

What I learned from one year of Substack
Over a year ago, I decided to change the trajectory of my newsletter. Before October 2022, I used Substack as a free way to inform my subscribers of new blog poss. Then, I realised that Substack could be much, much more. And the possibilities filled me with excitement.
Now, a year later, I can say that the enthusiasm is deflated, though still there. My conclusion is that to succeed on Substack, you need to put in a lot of work like any other platform. I’m fine with the work, but I also realise that a lot of it could still be out of your control and are influenced by encroaching social media-like algorithms on Substack, the dominant demographic on the platform and your social media klout.
Below are my observations, and feel free to chime in the comments if this has and has not been your experience.
- Being a part of the Substack community is a must to get more readers and attention to your Substack. That means commenting on other people’s Substacks, or participating in writing prompts (for Fiction readers). Now there’s Substack Notes, but it does feel like shouting into the ether especially if you’re a small fry. You’d be better off commenting on a high-traffic person’s posts.
- There’s no denying that if you are already an established name in your field, you will attract subscribers like flies. It used to puzzle me, because some of these high-traffic folks would post a photo and write something pithy about said photo and attract 40+ comments. Klout still matters on Substack.
- People with Klout are often promoted on Substack’s official newsletter. And if they are not established names, they already have thousands of subscribers. This can be dispiriting to some newbies, though inspiring to some. There should at least be a “new to Substack” section.
- As a reader, it is a struggle to find fresh new Substacks from unknowns. If you go through the Substack categories, they are often arranged by “who has the most followers” on top, and those who don’t have as many followers get buried at the bottom. Worse, the UI isn’t friendly either – it’s an endless scroll to the bottom. There must be an easier way for newbies to get seen instead of hoping that someone will have the energy to scroll all the way to the bottom.
- Substack’s search sucks.
- If you have zero klout, no name or connections, be reading for hard work. Producing content regularly and being social will get you somewhere.
- However, good content is paramount. I noticed that these types of content do well on Substack:
- You offer unique insights into a place/issue
- You teach people how to do well on Substack (this is very Medium, where most of the posts that gain traction is how to earn $$ in Medium)
- Fiction – if you offer both a and b with your fiction, you’ll do well
- If you’re a person with mental or physical challenges, keeping up with the demands of being “social” on Substack and producing constantly can be arduous and impossible. I knew what it took to succeed … but I just don’t have the mental capacity, and it can get depressing seeing others race in front of you but you’re held back by your disabilities/lack of energy. There’s no sugarcoating this – Substack is not geared for people like this.
- That said, there are amazing Substackers who have worked with their limitations or have boundaries. I admire Louise Stigell and Cali Bird for refusing to bow down to the gods of attention and productivity. Both remind me that I have to work with my mental levels and respect that. Don’t compare yourself to other people, especially if they are more productive.
- For low-energy people (mental or physical), publishing in seasons could be one way to do it. Talebones 🔭 is one who is doing that, though I do not see any breaks between seasons. I used to follow two creatives who struggle with physical illnesses, and one of the ways they cope is to publish seasonally, and that’s usually just about 6-7 months a year.
- Work on a stockpile of content first before publishing your first issue, if possible. Especially if you have mental and physical challenges. I realise that while I enjoy writing on the fly, there are weeks when I just can’t do it and had to stop writing.
- There are many interesting payment models on Substack, and as a reader and fiction writer I prefer the “archive older posts” method as it feels like I’m giving value to the subscribers but also giving new readers a chance to “try me out”.
- Offering ebooks to subscribers is also a good way to attract subscribers. Mario Cavolo and Simon K Jones does this.
- I used to enjoy Substack Notes. Now I don’t. It’s just full of so much hustle that it makes me irritated and depressed. I have this inner cavewoman who is demanding, “What can I do to get as much attention?” This pressure is something I am trying to avoid on social media. Also, I’m a person who can’t split myself between too many social media channels, and Mastodon is just more rewarding and hustle-free for me right now.
- Substack is a US-dominated platform and as a reader, it’s very … dispiriting? Tiring? Stifling? Boring? to always read fiction or essays from an American perspective. I’ve made an effort to hunt for more international content, but they are very far and few in between. And as a writer, I wonder if I could offer writing that would interest US-centric audiences. I think, possibly, but maybe some would find my content off-putting or alien. (I find that if you offer a different political perspective than the US/Western left/right cultural talking points, you’ll get a lot of pushback. Sometimes, animosity.)
- I still have no idea how to convert people to being paid subscribers. Fiction seems like an incredibly tough field for that, so I’m only wishing for the gods of Substack to smile down on me lol. And as the tech industry goes through massive layoffs, I find myself thinking about getting more subscribers so that I could have a rainy day stream of income, but the pressure of having to do so much to even get there is sucking all joy from my fiction writing.
- There’s a movement away from Substack as people realised they need to control where their content lives. Others like Justin Cox question its model. I found Louise Stigell’s comments interesting:
I’ve also been kind of reluctant to let so much of my content live somewhere other than on my website. It doesn’t matter that Substack is a great platform, and that I can move my content off it whenever I want. It doesn’t matter that I can monetize my content here. It’s still not my platform, and I have no control over the rollout of new features, visual changes, monetization policies, et.c. Some people have complained to me that I’m being too pushy trying to get them to pay for a subscription. Well, it’s not me doing the pushing, it’s Substack. It’s all automated and beyond my control. And ultimately, what matters the most to me in my business in control and autonomy. – Bye, Substack
So, there you have it. Substack gives me mixed emotions. On the one hand, I’ve been able to increase my subscriber base thanks to it. On the other hand, it gives me a lot of pressure at the same time. I’m not sure what to make of it! Except that I have way more fun on Mastodon and on my blog than on Substack and it’s making me wonder if I should leave it like some Substackers have.

There's a certain amount of cognitive dissonance in the #environmental movement between believing that humans are making the planet uninhabitable (for humans) and also wanting to change the trajectory so that humans can survive. Life will be just fine long after there are no humans on Earth. So as an environmentalist, are you for or against human extinction? The anti-human mindset can only exist if you feel that humans are seperate from other life: they are not. Else #twelvemonkeys

CW: Tuam mass child graves
CW/TW: Mass graves, religious abuse, mother and baby homes
The story of Tuam , Ireland 's mass graves has a very similar trajectory to those of the Indigenous children who died at residential schools in places like Kamloops, BC.
Many of the Irish press, officials, and most of all, the church, tried to deny that this happened.
But it did.These are some of their stories.

Journalist and technology writer Kaif Shaikh disagrees with #GayaHerrington, in this 2025 response. Kaif refers to #JoachimKlement, an economist, who believes that we are already on the way to a collapse, with society returning to the way it was in the 1900s (more about that in another post).
"So, where are we now, and what is the responsible takeaway?
"The 1972 framework still describes the structure of our situation. Herrington’s 2021 comparison shows that the world’s recent history has tracked World3’s growth-first pathways closely enough to warrant concern about declines later this century, potentially beginning to bite this decade. Her 2022 reflection adds two critical refinements. The divergence among futures happens after 2020, and the most livable path requires a conscious redesign of priorities toward efficiency, pollution control, and social investment rather than throughput.
"The Nebel et al. recalibration, as interpreted by Klement, indicates that even after re-estimating parameters with better data, the system still exhibits overshoot and collapse, with the trigger rooted in resource depletion. The implication is that 'more of the same, but faster' is not a strategy. It is precisely what turns today’s creativity into tomorrow’s fragility.
"If there is one message to carry forward, it is Herrington’s: the window for a deliberate trajectory change is narrow but real. The 'Stabilized World' is not a utopian fantasy layered onto a model. It emerges from the same feedback structure that produces overshoot under different goals. Change the goal, and the loops that currently amplify stress can be redirected to reinforce #resilience.
"That change looks less like a silver bullet and more like a portfolio of priorities that the model especially favors. Using fewer resources per unit of well-being, investing in pollution abatement so damages do not accumulate, and building health and education services that improve human welfare without relying on ever-rising material throughput.
"It is also important to be precise about uncertainty. The studies do not claim to know exactly when or how any particular nation will experience stress. #World3 is a global model of dynamics, not a country-by-country forecast. Nor do the authors claim that technology is useless.
"Quite the opposite. Technology can raise ceilings and delay peaks. But as co-author #DennisMeadows has often emphasized in discussions about #LimitsToGrowth over the years, higher peaks without structural change can mean sharper falls (#Overshoots).
"Herrington’s point is that 'technology plus the same goal' keeps us on the wrong curve. Technology deployed in the service of different goals, efficiency, abatement, and human development, separated from material throughput, can move us onto the SW trajectory.
"Finally, the recalibration’s note about system behavior under contraction deserves attention. If the world does tip into decline, feedbacks may rearrange themselves in ways the original model cannot fully capture. That is not a reason to dismiss the warning. It is a reason to move earlier, while our degrees of freedom are greater, and adaptation can be shaped rather than suffered. The studies summarized here do not argue that collapse is inevitable. They suggest that collapse is a real risk if we keep our current goals, and that avoiding it means choosing new ones."
