Cooling the Planet With a Space Shade Is Now Very Slightly More Plausible

I think it’s important to remember, as we see the warming climate break down our ecosystems and weather patterns, that we do have a sort of very limited “emergency break”, in the form of solar geoengineering. The term, in this context, refers to a few different actions that could be taken to lower Earth’s temperature without reducing greenhouse gas levels, by blocking or deflecting sunlight, before it can hit the surface of the planet, and turn into heat. The cheapest and most reliable method, at least in the short-term, is to release sulfate aerosols into the upper atmosphere, simulating a massive volcanic eruption, and reflecting sunlight to cool the planet. From what I can tell, there’s not much question that this would have a cooling effect. The problem is that it will also have other effects, which are less certain, on atmospheric chemistry and on ecosystems. Another one that’s often proposed is to make man-made surfaces white – rooftops, roads, parking lots – just make all of it more reflective. There’s zero question that this would have an effect, but it would be a fairly small effect, and it’s not clear to me what it would take to maintain that brightness. There are some others, which you can check out at first link, but today we’re going to talk about the “space-age” option.

See, if you want to reduce the sunlight hitting Earth’s surface, but you don’t want to have to worry about mucking with ecosystems and atmospheric chemistry, you can take the most literal option, and put a sun shade in space. From the University of Hawai’i:

One of the simplest approaches to reducing the global temperature is to shade the Earth from a fraction of the Sun’s light. This idea, called a solar shield, has been proposed before, but the large amount of weight needed to make a shield massive enough to balance gravitational forces and prevent solar radiation pressure from blowing it away makes even the lightest materials prohibitively expensive. Szapudi’s creative solution consists of two innovations: a tethered counterweight instead of just a massive shield, resulting in making the total mass more than 100 times less, and the use of a captured asteroid as the counterweight to avoid launching most of the mass from Earth.

“In Hawaiʻi, many use an umbrella to block the sunlight as they walk about during the day. I was thinking, could we do the same for Earth and thereby mitigate the impending catastrophe of climate change?” Szapudi said.

Incorporating a tethered counterbalance

Szapudi began with the goal of reducing solar radiation by 1.7%, an estimate of the amount needed to prevent a catastrophic rise in global temperatures. He found that placing a tethered counterbalance toward the Sun could reduce the weight of the shield and counterweight to approximately 3.5 million tons, about one hundred times lighter than previous estimates for an untethered shield.

While this number is still far beyond current launch capabilities, only 1% of the weight—about 35,000 tons—would be the shield itself, and that is the only part that needs to be launched from Earth. With newer, lighter materials, the mass of the shield can be reduced even further. The remaining 99% of the total mass would be asteroids or lunar dust used as a counterweight. Such a tethered structure would be faster and cheaper to build and deploy than other shield designs.

Today’s largest rockets can only lift about 50 tons to low Earth orbit, so this approach to solar radiation management would be challenging. Szapudi’s approach brings the idea into the realm of possibility, even with today’s technology, whereas prior concepts were completely unachievable. Also, developing a light-weight but strong graphene tether connecting the shield with the counterweight is crucial.

I know the billionaires have given space stuff something of a stink, but unlike fantasies of colonies on Mars or Venus, this is one way that improving our ability to do stuff in space could actually help with the climate crisis. There would certainly be pollution from launching any kind of space shade, and from getting to the point where we can do such a thing, but I don’t know how that would compare to the other options on the table.

As I’ve said before, this kind of geoengineering is dangerous, but probably unavoidable, because of long we’ve delayed action. It won’t matter much if we don’t also reduce greenhouse gas levels, but a slight drop in incoming sunlight could make things a lot easier, as long as we avoid the Futurama Solution. I guess the main question is – absent the kind of systemic political and economic change that I want to see, what will it take for “world leaders” to decide it’s time to shade the planet? What would it take for you to decide it’s time for that?

For me, I honestly don’t know. Doing it sooner might buy us some needed time, by delaying the melting of ice and thawing of permafrost, but the geopolitical and ecological ramifications worry me, because it seems like a foregone conclusion that the side effects would fall hardest on those with the least say in any of this. It sucks we’ve let things go so far, but I guess I’m glad that people are at least working out what it would take to shade the planet, and buy us a little more time.

Adaptation and Mitigation: Food Production in a Rapidly Warming World

So I’ve been advocating a move to indoor food production for a while, and I often get pushback on it, some of which… seems to miss the point. Someone linked me an article from 2018 over on Bluesky (follow me @abedrayton.bsky.social), as a reason why vertical farming “won’t save the world”. It’s an interesting article, for what it is, but it crucially does not address the main reason why I believe what I believe. Before I get into that, however, I want to address one other issue, because whenever this subject comes up, and I mention indoor farming and microbial food production, people ignore that latter part, to focus on the former. My guess is that this is because most people don’t know much about microbial food production, and so don’t have much to say about it, in which case, I should probably do more to talk about it. I’ll give an overview here, but I’ll also just try to post more about it going forward.

Mass production of microbial food is, as I understand it, a fairly new field. It focuses mostly on yeasts, edible bacteria, and microaglae, all of which can be grown in more of a factory than a farm. In both cases, the focus usually seems to be on growing them as a source of protein, to replace animal agriculture and soy beans. Because of that focus, a lot of discussion around this stuff seems to focus on the inefficiency and cost of animal agriculture as a source of emissions, rather than about the fact that food grown in a factory setting is less vulnerable to weather and pests than food grown in fields.

The main concern I have at this point in time – something I’m emailing scientists about – is how well it could replace grains. There’s no question that finding better sources of protein is important, because while I didn’t mention it in my recent post about simultaneous crop failure, one of the likely effects of that is the mass culling or starvation of livestock, because that’s what we do with 77% of the soy we grow. People in the US, at least, could stand to eat considerably less protein, but I don’t believe that forcing that through crop failure is a good way to go about it. That said, humans do actually need carbohydrates, so if microbes can’t produce enough of that, then we may need to think about other options.

I think microbes are still a part of those other options, too. If we do actually need to continue relying on outdoor grain farms, then we should probably not be using that land for things that we don’t need, like mass production of beef. In that way, even if we can only rely on algae and bacteria for protein, we’ll be able to grow and store more grain to guard against famine, so it still seems worth major investment to me.

With all of that dealt with, let’s go back to this article about vertical farms, that was presented as a rebuttal to my belief that we should be moving food production indoors, to guard against global crop failures. My problem is that it in no way addresses my concern, but rather discusses vertical farming’s expenses, and vertical farming as a way to reduce carbon emissions:

First, these systems are really expensive to build. The shipping container systems developed by Freight Farms, for example, cost between $82,000 and $85,000 per container — an astonishing sum for a box that just grows greens and herbs. Just one container costs as much as 10 entire acres of prime American farmland — which is a far better investment, both in terms of food production and future economic value. Just remember: farmland has the benefit of generally appreciating in value over time, whereas a big metal box is likely to only decrease in value.

Second, food produced this way is very expensive. For example, the Wall Street Journal reports that mini-lettuces grown by Green Line Growers costs more than twice as much as organic lettuce available in most stores. And this is typical for other indoor growers around the country: it’s very, very expensive, even compared to organic food. Instead of making food moreavailable, especially to poorer families on limited budgets, these indoor crops are only available to the affluent. It might be fine for gourmet lettuce, or fancy greens for expensive restaurants, but regular folks may find it out of reach.

Finally, indoor farms use a lot of energy and materials to operate. The container farms from Freight Farms, for example, use about 80 kilowatt-hours of electricity a day to power the lights and pumps. That’s nearly 2–3 times as much electricity as a typical (and still very inefficient) American home, or about 8 times the electricity used by an average San Francisco apartment. And on the average American electrical grid, this translates to emitting 44,000 pounds of CO2 per container per year, from electricity alone, not counting any additional heating costs. This is vastly more than the emissions it would take to ship the food from someplace else.

[…]

Proponents of indoor techno-farms often say that they can offset the enormous sums of electricity they use, by powering them with renewable energy — especially solar panels — to make the whole thing carbon neutral.

But just stop and think about this for a second.

These indoor “farms” would use solar panels to harvest naturally occurring sunlight, and convert it into electricity, so that they can power…artificial sunlight? In other words, they’re trying to use the sun to replace the sun.

But we don’t need to replace the sun. Of all of the things we should worry about in agriculture, the availability of free sunlight is not one of them. Any system that seeks to replace the sun to grow food is probably a bad idea.

[…]

Sometimes we hear that vertical farms help the environment by reducing “food miles” — the distance food items travel from farm to table — and thereby reduce fuel consumption and greenhouse gas emissions.

This sounds logical, but it turns out to be a red herring.

Strange as it might seem, local food typically uses about the same amount of energy — per pound — to transport as food grown far away. Why? Short answer: volume and method of transport. A larger food operator can ship food more efficiently — even if it travels longer distances — because of the gigantic volumes they work in. Plus, ships, trains, and even large trucks driving on Interstate highways use less fuel, per pound per mile, than small trucks driving around town.

Plus it turns out that “food miles” aren’t a very big source of CO2 emissions anyway, whether they’re local or not. In fact, they pale in comparison to emissions from deforestation, methane from cattle and rice fields, and nitrous oxide from over-fertilized fields. And local food systems — especially organic farms that use fewer fertilizers, and grass fed beef that sequesters carbon in the soil — can reduce these more critical emissions. At the end of the day, local food systems are generally better for the environment, including greenhouse gas emissions. Just don’t worry about emissions from food miles too much.

No shame to the author of this article, of course. He didn’t set out to discuss the merits of vertical farming as a guard against crop failure, so he didn’t do that. My problem is with the person who linked this article, because it doesn’t even acknowledge the main reason I want to move food production indoors, as much as we can. The article makes good points – building and operating something like a vertical farm absolutely is very resource-intensive, and the recommendations made at the end – that we focus on better farming practices – are 100% on-point. We need to do that.

But the question – for me – is not whether vertical farms are the most efficient way to grow food, compared to existing, more conventional methods, or whether they’re as profitable (accounting for subsidies). It’s whether they’re a more reliable way to grow food, in a rapidly warming climate. I don’t have a clear answer to that, in part because the focus in this sort of discourse is still mostly about reducing emissions and preventing the warming. That’s all important stuff to take into consideration, but I think we’ve reached a point where we also have to consider what it will take to keep people alive, because we haven’t actually made all of those changes to agriculture that everyone’s been talking about for the last few decades. The clear answer I do feel I have, is that the odds of global crop failure are increasing, and if we don’t plan for that eventuality, a lot of people are going to die needlessly.

The other point made on Bluesky, and I think it’s a good one, is the concern that a shift in food production would hurt people who are currently farmers. My answer to that is twofold. First, as with fossil fuel workers, we as a society have a responsibility to make sure that farm workers are not left destitute because of a societal change over which they had no control. I think nobody should be left destitute in a world with abundant resources, but we should also have dedicated programs to making sure farmers are taken care of.

Second, and I think this is more important, investing in indoor food production should not come at the expense of outdoor food production, at this stage. The reason I want to do it now, is that we don’t need it now, but everything I’ve seen about the rate of warming and the effects of warming suggests that we will need it in the not-so-distant future. I expect that if we make this investment, and shift away from animal agriculture, that will free up farmland, which can then be put to different use, but the first priority is feeding humanity, which means that at this stage, we still need normal farms, operated more responsibly as the article above suggests. We have the resources to do both, while also working to end fossil fuel use, and one of the downsides of so many decades of inaction is that we now also have a growing need to do both, as the temperature continues to rise.

Drilling Deep: Methane, Hydrothermal Vents, and a False Alarm

Dear Readers, I would like to take you on a short emotional journey. I was browsing science headlines, and I came across one that had me worried for a good minute. Past climate warming driven by hydrothermal vents, with a sub-header specifying methane release from these vents as the driver of a warming event 55 million years ago. I imagine many of you already know why this caught my attention. Methane is well-known as a potent greenhouse gas, emitted by both fossil fuel extraction, and animal agriculture. It also exists in massive sea-floor deposits called “clathrates” or “hydrates”, in which a combination of low temperatures and high pressure create stable ice formations. The clathrate gun hypothesis is a proposal to explain warming during the Quaternary period, and it basically suggests that these deposits can destabilize, release all their methane, which would bubble up through the water into the atmosphere, driving an increase in global temperature.

The fear for us has been that this could be triggered by the warming of the oceans, adding fuel to the fire that is global warming. Last October, I posted about new research indicating that this was not actually likely to be a serious problem. See, getting the right combination of temperature and pressure for clathrates to form requires them to be deep enough under water, that the gas released by them is pretty much entirely absorbed:

New research from scientists at the University of Rochester, the US Geological Survey, and the University of California Irvine is the first to directly show that methane released from decomposing hydrates is not reaching the atmosphere.

The researchers, including John Kessler, a professor in the Department of Earth and Environmental Sciences, and DongJoo Joung, a former research scientist in Kessler’s lab and now an assistant professor in the Department of Oceanography at Pusan National University in Korea, carried out the study in mid-latitude regions—Earth’s subtropical and temperate zones.

While the stability of the methane hydrate reservoir is sensitive to changes in temperature, “in the mid-latitude regions where this study was conducted, we see no signatures of hydrate methane being emitted to the atmosphere,” says Joung, the first author of the study, published in Nature Geoscience.

Reading about this research was a load off my mind. There are a number of ways in which global warming could make things go sideways really fast. The jaw-dropping spike in ocean temperatures that we’ve been seeing this year have, I think, alerted more people to that possibility, but for a while, the clathrate gun was the thing that worried me the most. A big part of the problem with global warming is the speed at which it’s happening. If it had taken us ten thousand years to warm the earth this much, ecosystems might have been able to adapt better, and we would have had a much easier time ending fossil fuel use. Unfortunately, it’s taken us something more like 150 years, and that’s already more than we can handle, based on how things are going. A sudden, massive release of methane into the atmosphere could speed that up even more, and that would try even my ability to be optimistic.

So, I see this new headline, about methane emissions from hydrothermal vents, and I immediately think of the hydrothermal vents with which I’m most familiar – the ones that exist deep in the ocean, surrounded by tube worms and furry crabs. The last month has been pretty stressful for me, and I was not looking forward to hearing confirmation that deep-sea methane could, in fact, reach the surface.

Fortunately, that is not what I read.

About 55 million years ago, the Atlantic Ocean was born. Until then, Europe and America were connected. As the continents began to move apart, the Earth’s crust between them ruptured, releasing large volumes of magma. This rift volcanism has led to the formation of large igneous provinces (LIPs) in several places around the world. One such LIP was formed between Greenland and Europe and now lies several kilometres below the ocean surface. An international drilling campaign led by Christian Berndt, Professor of Marine Geophysics at GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany, and Sverre Planke, Professor of Marine Geophysics at the University of Oslo, Norway, has collected extensive sample material from the LIP, which has now been evaluated.

In their study, published today in the journal Nature Geoscience, the researchers can show that hydrothermal vents were active at very shallow depths or even above sea level, which would have allowed much larger quantities of greenhouse gases to enter the atmosphere than previously thought [emphasis mine].

Phew! Looks like we’re still in the clear.

With that anxiety now quelled, let’s take a look at how the researchers came to this conclusion, because it was quite the endeavor:

“At the Paleocene-Eocene boundary, some of the most powerful volcanic eruptions in Earth’s history took place over a period of more than a million years,” says Christian Berndt. According to current knowledge, this volcanism warmed the world’s climate by at least five degrees Celsius and caused a mass extinction – the last dramatic global warming before our time, known as the Paleocene-Eocene Thermal Maximum (PETM). Geologists have not yet been able to explain why, as most modern volcanic eruptions cause cooling by releasing aerosols into the stratosphere.

Further studies of the Karoo large igneous province in South Africa revealed an abundance of hydrothermal vents associated with magmatic intrusions into the sedimentary basin. This observation among others led to the hypothesis that large amounts of the greenhouse gases carbon dioxide and methane could have entered the atmosphere through hydrothermal venting. “When our Norwegian colleagues Henrik Svensen and Sverre Planke published their results in 2004, we would have loved to set off immediately to test the hypothesis by drilling the ancient vent systems around the North Atlantic,” says Christian Berndt. But it wasn’t that easy: “Our proposal was well received by the Integrated Ocean Drilling Program (IODP), but it was never scheduled because it required riser drilling, a technology that was not available to us at the time.”

As the research progressed hydrothermal vent systems were discovered that were within reach of riserless drilling. Thus, the drilling proposal was resubmitted, and the expedition could finally begin in autumn 2021 – 17 years after the first proposal was submitted.

Around 30 scientists from 12 nations took part in the IODP (now the International Ocean Discovery Program) research cruise to the Vøring Plateau off the Norwegian coast on board the scientific drilling ship “JOIDES Resolution”. Five of the 20 boreholes were drilled directly into one of the thousands of hydrothermal vents. The cores obtained can be read by scientists like a diary of the Earth’s history. The results were compelling.

The authors show that the vent was active just before the Paleocene Eocene Thermal Maximum and that the resulting crater was filled in a very short time, just as the global warming began. Quite unexpectedly, their data also show that the vent was active in a very shallow water depth of probably less than 100 metres. This has far-reaching consequences for the potential impact on the climate. Christian Berndt: “Most of the methane that enters the water column from active deep-sea hydrothermal vents today is quickly converted into carbon dioxide, a much less potent greenhouse gas. Since the vent we studied is located in the middle of the rift valley, where the water depth should be greatest, we assume that other vents were also in shallow water or even above sea level, which would have allowed much larger amounts of greenhouse gases to enter the atmosphere”.

As far as today’s climate warming is concerned, there are some interesting conclusions to be drawn from the cores. On the one hand, they do not confirm that the global warming at that time was caused by the dissolution og gas hyrates [sic] – a danger that has been much discussed in recent years. On the other hand, they show that it took many millennia for the climate to cool down again. So the Earth system was thus able to regulate itself, but not on time scales relevant to today’s climate crisis.

Reading that feels a bit like reading about a city built on top of another city, with the ancient ruins still down there to be explored. I get that in principle, this isn’t much different from taking any other geological core samples, but it feels different to me for some reason.

Regardless, while the researchers did not make this connection in these materials, I think that for our purposes, we can take some comfort from the shallowness of these ancient vents. Obviously, global warming is a crisis that demands great urgency, and this changes that not one bit. Clathrate gun or no, we are running out of time. The reason I wanted to share this (aside from it just being interesting research), is that I think it’s genuinely helpful to know at least one of the ways in which everything could get suddenly worse, isn’t something we need to worry about.

Should we be worried about ancient frozen bugs? Yes, but not for the reasons you might think.

Human discourse about pathogens tends to be pretty narrowly focused on those viruses and organisms that directly infect humans. This is, I think, entirely understandable. Our health is hugely important to every aspect of our lives, as we all become aware when we get sick, or develop chronic health problems. I know nobody reading this has any personal experience with this, but if you add in something like an epidemic that goes global, well that adds a whole other layer to it. We have ample reason to be somewhat obsessed with our health and things that affect it.

Second to that, we care about the health of our food and our working and companion animals, which I would argue is also mostly about our own health.

Less attention is given to how pathogens affect wildlife. We tend to view nature as something that takes care of itself, when we’re not actively destroying it, but of course other life forms have all the same health concerns we do, adjusted for the specifics of their species. More than that, humans have acted as something akin to global plague rats, as we’ve scurried about all over the surface of this planet, introducing animals, plants, and microorganisms everywhere we go. Well, now we’ve found a new way to introduce microbes are new to our ecosystems, this time because of their age.

We’ve seen it in science fiction and horror, folks, and now it’s time for the real life version. Are you prepared for a panoply of prehistoric pathogens?

The idea that “time-traveling” pathogens trapped in ice or hidden in remote laboratory facilities could break free to cause catastrophic outbreaks has inspired generations of novelists and screenwriters. While melting glaciers and permafrost are giving many types of dormant microbes the opportunity to re-emerge, the potential threats to human health and the environment posed by these microbes have been difficult to estimate.

In a new study, Strona’s team quantified the ecological risks posed by these microbes using computer simulations. The researchers performed artificial evolution experiments where digital virus-like pathogens from the past invade communities of bacteria-like hosts. They compared the effects of invading pathogens on the diversity of host bacteria to diversity in control communities where no invasion occurred.

The team found that in their simulations, the ancient invading pathogens could often survive and evolve in the modern community, and about 3 percent became dominant. While most of the dominant invaders had little effect on the composition of the larger community, about 1 percent of the invaders yielded unpredictable results. Some caused up to one third of the host species to die out, while others increased diversity by up to 12 percent compared to the control simulations.

The risks posed by this 1 percent of released pathogens may seem small, but given the sheer number of ancient microbes regularly released into modern communities, outbreak events still represent a substantial hazard. The new findings suggest that the risks posed by time-traveling pathogens — so far confined to science fiction stories — could in fact be powerful drivers of ecological change and threats to human health.

I tend to have mixed feelings about this kind of simulation research, but there is no question that there are viruses, bacteria, and even roundworms that were frozen tens of thousands of years ago (or thousands of thousands, in the case of that bacterium), and that are viable once thawed. While it’s certainly possible some of them could directly infect humans, it’s far more likely that the danger from these ancient microbes lies in their potential to further disrupt ecosystems that are already collapsing under the weight of habitat destruction, pollution, and global warming.

Some of you may recall that I posted last year about the way European earthworms have been colonizing and altering North American ecosystems for centuries, to the point where most folks in the US have never seen an indigenous earthworm. More recently, there was that research indicating that invasive species cause more economic damage than earthquakes, so you can see why some people might have fears about ancient frozen bugs that have absolutely nothing to do with worrying about the next pandemic.

As I so often say, humans are part of the ecosystems that surround us, and we ignore that fact at our peril. The physical changes that we’ve caused on the surface of our planet are devastating, and they’re more than enough to cause a mass extinction all by themselves. Add in prehistoric organisms, which could end up altering the climate themselves, and it’s hard to tell what could happen. Unfortunately, it’s also very easy to look at all of this and feel some level of despair. I do get that, and of course I feel it myself sometimes, but I continue to believe that we have the means to survive this crisis, as a species. That window of opportunity is closing, but it’s never over till it’s over, and the more we understand about what’s happening, the better our chances of finding a way through.

Video: Unions Will Save America

Working on things that are stressful and important for me to do, but that do not translate to a blog post at this point in time, so here’s a nice video about how unions will save America. I haven’t watched much of Leeja Miller’s stuff, but I like what I’ve seen so far. This video gives an overview of the history of unions in the US, makes the case for unions as a unifying force for the working majority of the country, and closes with suggestions about how you – yes, you – could get involved.

White Like Me: Reflections on Race from a Privileged Son

I’m doing organizational work today, so in lieu of a “real” post, I’m going to ask you to watch/listen to this lecture by Tim Wise. I think this is an important perspective on US history and society, with implications and applications for other parts of the world as well. Listening to it now, it puts me in mind of a quote from the late Michael Brooks:

Be ruthless with systems, but be kind to people.

I think I struggle with the latter at times, but it’s a good reminder to try to do better.

 

Video: Amsterdam Just Closed their Busiest Road

All cities have their charms and their flaws, but every time I watch a video from Not Just Bikes, I find myself wanting to live in Amsterdam. While it seems like there’s even more never-ending construction there than in most other cities, the governing philosophy seems very appealing, at a glance. Amsterdam puts a lot of effort not just into economic and building activity, but into finding and enacting new ways to make the city more pleasant for the people living in it. The construction is probably at odds with this goal, but it means that there’s always something new going on. Amsterdam had a period, in the 1960s, when they built some pretty big roads in an effort to join the trend of redesigning cities around cars. Now, they’ve closed their busiest road to car traffic for a period of six weeks, from 6am to 11pm, so that they can study how that affects traffic for the rest of the city. At the same time, there are community events and temporary decorations to help give an idea of what life would be like without that road. I imagine this will make life less pleasant for a number of people who drive, but Amsterdam is a good city for getting around without cars, and is known as one of the most bike-friendly cities in the world. The video below breaks down what’s happening, and the context in which it’s happening, and it makes me wish more cities were willing to experiment with design like this.

Video: The Minneapolis Police Department Is a Criminal Organization

Big Joel is one of my “comfort” Youtubers. Most of his stuff is what I would call cultural criticism and/or commentary. If you want a deep dive into Shrek or The Lorax, he’s your guy, and while he does do a fair amount of political commentary, he tends to approach the people or media he’s looking at from that same cultural perspective. Probably my favorite example of this is his video deconstructing another Youtuber’s attempt at a “takedown” as a cultural work. Today, however, he put out a different sort of video, and I think it’s worth sharing. It’s a simple premise – he goes through the DOJ report on the federal investigation into the Minneapolis Police Department, that was conducted following the murder of George Floyd, and discusses the clear evidence of systemic abuse and criminality. It’s a bit rough to listen to, but I think this video is worth your time, for a couple reasons. The first is that it’s important to understand just how widespread and systemic this kind of abusive behavior is. It’s not just the “bad apples” who harass, rob, assault, injure, maim, and kill people, it’s also their fellow cops who cover for them, and supervisors who lie on reports for them. As the video lays out pretty clearly, these are people who revel in abusing their power and using violence against powerless people for no apparent reason other than their own sadistic pleasure.

The second reason, as I’ll discuss after the video, is that I do not think this is a widespread systemic problem within the Minneapolis Police Department, but rather within US policing as a whole. You should view this report as a representative sample of the profession.

So, why do I feel comfortable saying that Minneapolis is representative of a nationwide problem?

Well, regular readers will know that I’ve touched on this issue in the past. Cops in Atlanta make a regular appearance here, for their murderous campaign to force through a massive training facility. Austin PD decided to openly defy a law requiring more civilian oversight. A black kid in Mississippi called the cops for help, and they shot him. The DOJ investigation in to the Ferguson PD after the killing of Michael Brown found a similar pattern of widespread abuse of power, targeting of minorities, and cops lying to cover for each other. Across the US, cops steal more from people than burglars do, and the list goes on.

People defending the police might respond by saying that yes, they brutalize people, and guarantee that most of our rights only exist on paper, but we need them anyway, because the main thing they do is solve crime. Well, no. Not really.

(Reuters) – A new report adds to a growing line of research showing that police departments don’t solve serious or violent crimes with any regularity, and in fact, spend very little time on crime control, in contrast to popular narratives.

The report was published Oct. 25 by advocacy group Catalyst California and the ACLU of Southern California. It relies on county budgets’ numbers and new policing data provided under the state’s Racial and Identity Profiling Act, which took effect in 2019.

The law requires police to report demographic and other basic information about their work, including the duration of a stop and what actions were taken, like ordering someone out of a car.

Records provided by the sheriff’s departments in Los Angeles, Sacramento, San Diego and Riverside showed the same longstanding pattern of racial disparities in police stops throughout the country for decades. Black people in San Diego were more than twice as likely than white residents to be stopped by sheriff’s deputies, for example.

More notably, researchers analyzed the data to show how officers spend their time, and the patterns that emerge tell a striking story about how policing actually works. Those results, too, comport with existing research showing that U.S. police spend much of their time conducting racially biased stops and searches of minority drivers, often without reasonable suspicion, rather than “fighting crime.”

Overall, sheriff patrol officers spend significantly more time on officer-initiated stops – “proactive policing” in law enforcement parlance – than they do responding to community members’ calls for help, according to the report. Research has shown that the practice is a fundamentally ineffective public safety strategy, the report pointed out.

In 2019, 88% of the time L.A. County sheriff’s officers spent on stops was for officer-initiated stops rather than in response to calls. The overwhelming majority of that time – 79% – was spent on traffic violations. By contrast, just 11% of those hours was spent on stops based on reasonable suspicion of a crime.

In Riverside, about 83% of deputies’ time spent on officer-initiated stops went toward traffic violations, and just 7% on stops based on reasonable suspicion.

Moreover, most of the stops are pointless, other than inconveniencing citizens, or worse – “a routine practice of pretextual stops,” researchers wrote. Roughly three out of every four hours that Sacramento sheriff’s officers spent investigating traffic violations were for stops that ended in warnings, or no action, for example.

Researchers calculated that more of the departments’ budgets go toward fruitless traffic stops than responses to service calls — essentially wasting millions of public dollars.

Chauncee Smith, a senior manager at Catalyst California, told me they wanted to test the dominant media and political narrative that police agencies use public funds to keep communities safe.

“We found there is a significant inconsistency between their practices” and what the public might think police do, Smith said. “It begs the question of why we keep doubling down on public safety strategies that have been proven time and time again to fail.”

The departments were mostly non-responsive to my questions.

Yeah, I bet.

The reality is that police do far more harm than good, and the vast majority of things they do either need to stop happening altogether, or need to be done by healthcare professionals and social workers. Traffic enforcement, to the degree that it’s needed can be done by automated camera, or at the very least by people who aren’t armed, and are under no obligation to chase down a fleeing “suspect”.

Police in the United States do not serve the communities in which they work. The good they happen to do is largely incidental, due to the fact that they’re the default first responder to everything. They’d have to be really dedicated to never do any good. No, their primary purpose is maintaining social order. That’s why rich people are happy to fund a place like Atlanta’s Cop City, where police will train in urban warfare, the better to control rowdy peasants. That’s why nothing is being done about the staggering amount of theft they commit, too – the victims are poor people, and in the eyes of the ruling class, poor people deserve their poverty, and have no real right to property or anything else.

I’m perfectly willing to accept that society needs first responders, including some trained in the use of arms. What we do not need, is anything resembling what policing has been throughout its history in the United States. The Minneapolis Police Department is a criminal organization, and it is not alone.

Scams of the Future: Surviving OceanGate Co-Founder Promises His Venus Colony Will Be Safe

Hey, y’all remember that submarine full of foolish rich people that imploded near the Titanic? I know it didn’t get much coverage, but since I was in the tiny minority of people who actually knew about it, I thought it made a great illustration of the hubris and incompetence of the aristocracy chosen by capitalism. Well, it turns out that the surviving co-founder of Oceangate, owners and operators of that submersible deathtrap, wants to send people to Venus. Venus.

But OceanGate is not Söhnlein’s only venture. The businessman’s latest — and possibly grandest — endeavor is to send 1,000 humans to live in Venus’ atmosphere by 2050.

Söhnlein hasn’t let the recent events dampen his ambition and claims humanity needs to continue pushing the limits of innovation.

He maintains his plan is not as crazy as it seems. “I think it is less aspirational than putting a million people on the Martian surface by 2050,” he told Insider.

Though it’s often called “Earth’s twin,” Venus doesn’t seem like the ideal place for humans to thrive.

Even Söhnlein agrees. “You’re absolutely right that when you talk about going to Venus, it would raise eyebrows outside the space industry. And it even raises eyebrows inside the space industry,” he said.

Venus is the warmest planet in the solar system. Its atmosphere is chock-full of carbon dioxide, its surface temperature could melt lead, and sulfuric acid rains down from its clouds. Its atmospheric pressure is crushing — more than 90 times that of Earth, according to NASA.

In spite of this, Söhnlein doesn’t see why humanity shouldn’t attempt to live on the planet. He points to research that suggests there is a sliver of the Venusian atmosphere about 30 miles from the surface where humans could theoretically survive because temperatures are lower and pressure is less intense.

If a space station could be designed to withstand the sulfuric acid in the clouds, Söhnlein says, hundreds to thousands of people could someday live in the Venusian atmosphere.

He says a floating colony could hold 1,000 people in the Venusian atmosphere by 2050, although exactly how this will happen is less clear.

Well, I’ll give him one thing – I think his plan has about as much chance of success as Elon Musk’s plan, given that, as far as I can tell, Musk has been largely pretending that the radiation problem doesn’t exist. For those who are unaware, our atmosphere and magnetosphere shield us from being constantly bathed in radiation. Out in space, and on a planet like Mars that has a thin atmosphere and no magnetosphere, there’s a real risk of radiation sickness, cancer, and more fun problems:

NASA’s current risk models assert that radiation-based cancer mainly comes from cosmic rays messing with our DNA, but the team’s new model suggests the reality could be far worse. After studying tumors in mice, the researchers believe that cells damaged by cosmic rays could actually impact other healthy cells around them, like a deadly domino effect.

“Galactic cosmic ray exposure can devastate a cell’s nucleus and cause mutations that can result in cancers,” Cucinotta explained in a statement. “We learned the damaged cells send signals to the surrounding, unaffected cells and likely modify the tissues’ microenvironments. Those signals seem to inspire the healthy cells to mutate, thereby causing additional tumors or cancers.”

Worst of all, spacesuits probably won’t help much.

“Exploring Mars will require missions of 900 days or longer and includes more than one year in deep space where exposures to all energies of galactic cosmic ray heavy ions are unavoidable,” Cucinotta said in a statement. “Current levels of radiation shielding would, at best, modestly decrease the exposure risks.”

Clearly, more research will have to be conducted in order to confirm just how at-risk Martian explorers will be, and what can be done to protect them from cosmic rays (mice aren’t humans, after all). But to add one last bummer layer of news, Mars has a super thin atmosphere—less than one percent of Earth’s—so it will expose people to even more radiation once they land. Hopefully, this all gets sorted out soon before the Martian colonies begin, because goddamn would that be disastrous.

Does anyone seriously think that one of the geniuses behind the Titan submersible is going to do space travel safely? It’s not just the radiation, though, because as mentioned above, Söhnlein says he wants a colony on Venus, either by somehow making it entirely acid-proof, or relying on the extremely long-shot hypothesis that readings of ammonia might mean that a portion of the upper atmosphere might not be entirely made up of clouds of sulfuric acid.

I don’t really think that this guy is going to try to send people to Venus by 2050. Honestly, I think by then, climate change will have caused enough problems that if we’re still capable of space flight, nobody’s going to want to indulge billionaire escapism. Is that optimistic? Maybe, but I think what this guy is actually doing, is conning his fellow rich assholes out of their money.

That said, Söhnlein is now famous for being part of a group that needlessly ignored serious and credible warnings, and got five people killed in one of the most horrific (if mercifully quick) ways it’s possible to die. The man’s record indicates that he might very well try to send people to Venus, and in that case, I think that space may become the latest and most horrific frontier in libertarians conning each other.

When I say “libertarians”, I’m talking about the US version of libertarians, as inspired by Ayn Rand’s philosophy of Objectivism – people who want free-market capitalism without any government interference, because they haven’t figured out that capitalism is utterly dependent on government interference to keep capitalists intact and in power. Self-styled “anarcho-capitalists (ancaps for short) are another version of the same, who mistakenly believe that because they want to be governed by capitalists, without any “real” government involved, that that makes them anarchists. For many of these people, there’s a sort of frontiersman fantasy that they keep coming back to that takes a couple forms. The basic fantasy of both of them, is to go somewhere out of reach of the interference of governments, where they will naturally thrive, uplifted by the raw power of human innovation, unshackled from the limitations of small-minded cowards who don’t want to die because a rich person thinks workplace safety is a waste of money.

The first, and most theoretical, is seasteading – the idea of building a city-state on something like an old oil rig. The one I think is more applicable is the Flying Dutchman of Objectivism, Gault’s Gulch. For the uninitiated, this is a reference to Ayn Rand’s novel, Atlas Shrugged, in which a rail tycoon storms off to some secluded capitalist utopia, along with his fellow rich people, thus leaving all of us poors to, in the words of the author, starve in our hopeless ineptitude. My favorite example of an attempt to do this took place in Chile, back in 2013 before the people put the left back in charge. I say it was an attempt, but true to the spirit of Ayn Rand and US libertarianism, not everyone was in it for the dream:

Galt’s Gulch, Chile was a libertarian paradise and completely obvious catastrophe conceived by John Cobin, Germán Eyzaguirre, Jeff Berwick,Wikipedia and Ken Johnson.[2] GGC claimed to feature 11,000 acres of land located in picturesque valleys full of fresh air in a low-tax country, where Randians who believed in capitalism, limited government, and self-reliance would be able to form a sustainable community that expressed their ideals. (Spoiler: It went to shit.)

Soon after the first parcel of land was placed under agreement, conman Ken Johnson was able to defraud his partners of their share of the project and take complete control.[3] He did not work to develop the properties for a community, but instead worked an affinity scam. Johnson used Berwick and other libertarian “celebrities” to dupe his victims. He even offered discounts for those who paid in Bitcoin or precious metals as part of the confidence scheme.

Johnson started selling properties in late 2013 and early 2014 until a marketing event in April 2014, where it was found that the properties had never been zoned for sale (i.e., no approved master plan, water rights not transferred to GGC). Also, there were a number of outstanding bills to contractors that had not been paid (and who refused to perform further work). After seeing Johnson’s presentation, a number of the original investors who attended the event lost faith in the project and requested their money back.[4] According to his investors and his erstwhile partners, Johnson never did his due diligence before buying the properties. His defense of the dismal situation was to rant about unknown enemies of the project all around.

Just prior to the April 2014 marketing event, the GGC bank account had been blocked to receiving international wires due to Johnson’s violations of the know-your-customer regulation in Chile. He was approached by Chilean swindler Mario Del Real who convinced Johnson that the GGC corporations were not legally structured and that Johnson should partner with Del Real to rectify the situation. Del Real also offered his daughter’s bank account for GGC’s use. Inexplicably, Johnson agreed to this obvious scam and ultimately transferred half ownership of GGC to Del Real. This began a finger-pointing soap opera between the swindling partners which has stuck the project in limbo and the Chilean courts.[5][6]

Apparently John Cobin took his love of capitalism so seriously that he ended up being locked up for shooting anti-government protesters in 2020, ahead of the 2021 general election.

I think this is the kind “space colonization” we can expect over the next couple decades – people investing money in a pipe dream, and never seeing a return on that. There may well be some real attempts, and I think they’ll be expensive and end in tears, but mostly, it’s a con. Unfortunately, it looks like we can expect taxpayers to be some of the most profitable marks in that con, which brings us back to the sad reality of our warming world.

In principle, I have no problem with billionaires killing themselves through their own hubris. It’s not like they haven’t been warned, and it’s not like the world would be worse off for their absence. The problem is, we can’t afford the resources that are already being poured into their vanity projects. We’ve got problems aplenty here on Earth, and the “solutions” that the billionaires want us to fund start with the assumption that the lives of everyone on this planet, except the billionaires themselves, are meaningless. To them, saving humanity means making this planet uninhabitable, in pursuit of helping people like Musk and Söhnlein escape to somewhere they can play space king. It’s no different from the billionaires building mansion bunkers and planning to use shock collars to control their security guards, except that we’re all funding the “space bunkers” not just through exploitation and wage theft, but also through our taxes and the pollution caused by their rockets.

There’s one way I’ll reconsider, though. I will entertain suggestions to send all the ultra-rich to Mars and Venus in whatever spacecraft we have lying around, say, next year? Then maybe the rest of us can get on with saving humanity.

Video: Let’s talk about heat, pavement, and Arizona mostly…

I talk a lot about parts of the world becoming uninhabitable, as the temperature rises, but I generally focus on stuff like the increase in wet bulb conditions. Beau of the Fifth Column has rightly pointed out that there’s another way in which heat makes the outdoors dangerous – the temperature of pavement. As you’re probably aware, when temperatures climb past the 90s, asphalt in the sun can get literally hot enough to fry eggs. Those conditions are increasing as well, meaning that for longer periods of the year, simply falling over can give you severe, even life-threatening burns. This is a good reason to be careful during heatwaves (be careful of your dogs as well – their paws cook just as easily as our skin), but it’s also a good reason not to keep expanding roads and car-dependence. Paving the world is increasingly going to turn places like parking lots into death traps. Content warning for descriptions of burns:

“Summers are our busy season, so we anticipate that this sort of thing is going to happen. But this is really unusual — the number of patients that we’re seeing and the severity of injuries — the acuity of injuries is much higher,” said Dr. Kevin Foster, director of burn services at the Arizona Burn Center at Valleywise Health. “The numbers are higher and the seriousness of injuries are higher, and we don’t have a good explanation for it.”

Every single one of the 45 beds in the burn center is full, he said, and one-third of patients are people who fell and burned themselves on the ground. There are also burn patients in the ICU, and about half of those patients are people burned after falls.

“It has definitely taken its toll,” Foster said.

The area has been hotter than usual, even for Arizona, and that, experts said, means that the ground can be dangerous for anyone whose bare skin comes into contact with it.

Asphalt is dark and dense. While concrete is lighter and reflects some sunlight, when the sun shines on asphalt, its dark color causes it to absorb light and it heats up.

Since it is a dense material, it also holds the heat even after the sun has been shining on it.

On a hot day, asphalt can easily be 40 to 60 degrees hotter than the air, some studies show. Last Thursday, the air temperature reached 119 degrees Fahrenheit. Phoenix had six consecutive days at or above 115 degrees by Saturday; the streak ended Sunday, with high temperatures reaching only 114 degrees.

“The temperature of asphalt and pavement and concrete and sidewalks in Arizona on a warm sunny day or summer afternoon is 180 degrees sometimes. I mean, it’s just a little below boiling, so it’s really something,” Foster said.

It can take only a “fraction of a second” to get a “pretty deep burn,” he said. For people who have been on the pavement for 10 to 20 minutes, “the skin is completely destroyed” and the damage often goes down deep, meaning it is a third-degree burn.

Foster sees burns like that after people survive a house fire. “These are really serious injuries,” he said.

Patients with third-degree burns will require multiple surgeries and have to spend weeks or even months in the hospital and have years of reconstructive surgery and therapy. “It is a really substantial injury,” Foster said.

Be careful out there!
