Here is an interactive chart of greenhouse gas concentrations from the World Meteorological Organization. It does look to me like there has been an acceleration in methane concentrations since around 2020.

2024 in Review
Intro
What I do here is list all the posts I picked each month as most frightening, most hopeful, and most interesting. Then I attempt some kind of synthesis and analysis of this information. You can drill down to my “month in review” posts, from there to individual posts, and from there to source articles if you have the time and inclination.
Post Roundup
Most frightening and/or depressing stories
- JANUARY: 2023 was “a year of war“, and so far 2024 is not looking better. Those diplomatic grand bargains you always hear about seem to be getting less grand. And the drumbeat for a U.S. attack on Iran got louder.
- FEBRUARY: The war on terror continues, and the propaganda umbrella has expanded to cover attacks on any group labeled as “Iran-backed”. Fentanyl gets an honorable mention, but affects mostly the poor and miserable whereas the war on terror threatens to immolate us all.
- MARCH: Ralph Nader says the civilian carnage in Gaza is an order of magnitude worse than even the Gaza authorities say it is. Which is almost unthinkably horrible if true, and makes the Israeli public statements about collateral damage seem even less credible. However even handed you try to be in considering this war could be a proportionate response to the original gruesome attack, it is getting harder.
- APRIL: Peter Turchin’s description of a “wealth pump” leading to stagnation and political instability seems to fit the United States pretty well at this moment. The IMF shows that global productivity has been slowing since the US-caused financial crisis in 2008. In Turchin’s model, our November election will be a struggle between elites and counter-elites who both represent the wealthy and powerful. That sounds about right, but I still say it is a struggle between competence and incompetence, and competence is a minimum thing we need to survive in a dangerous world. In early April I thought things were trending painfully slowly, but clearly, in Biden’s direction. As I write this in early May I am no longer convinced of that.
- MAY: What a modern nuclear bomb would do to a large modern city. Do we already know this intellectually? Sure. Do we constantly need to be reminded and remind our elected leaders that this is absolutely unthinkable and must be avoided at any cost? Apparently.
- JUNE: Some self-labeled “conservatives” in the United States want to do away with the National Oceanic and Atmospheric Administration, the Census Bureau, the Internal Revenue Service, the Federal Emergency Management Agency, the National Institutes of Health, the Department of Education, and possibly even the Federal Reserve. All these are needed to have a competent, stable government and society and to be prepared to respond and recover from the shocks that are coming, so I would call this nihilist and not “conservative” at all. How is it conservative to want to destroy the institutions that have underpinned the success of our nation thus far? On the other hand, they also want to double down on the unimaginative pro-big-business, pro-war consensus of the two major parties over the last 50 years or so, which has also gotten us to where we are today. And it looks like the amateurs and psychopaths have the upper hand at the moment in terms of our November election. This is certainly not “morning in America”.
- JULY: Joe Biden’s depressing decline in the international spotlight, and our failed political system that could let such a thing happen. Not much more I can say about it that has not been said. The “election trifecta” – non-partisan, single ballot primaries; ranked-choice general elections; and non-partisan redistricting – is one promising proposal for improving this system.
- AUGUST: Human extinction, and our dysfunctional political system’s seeming lack of concern and even active ramping up the risk. We have forgotten how horrible it was last time (and the only time) nuclear weapons were used on cities. Is there any story that could be more frightening and/or depressing to a human?
- SEPTEMBER: There is nothing on Earth more frightening than nuclear weapons. China has scrapped its “minimal deterrent” nuclear doctrine in favor of massively scaling up their arsenal to compete with the also ramping up U.S. and Russian arsenals. They do still have an official “no first strike” policy. The U.S. by contrast has an arrogant foreign policy.
- OCTOBER: When it comes to the #1 climate change impact on ordinary people, it’s the food stupid. (Dear reader, I’m not calling you stupid, and I don’t consider myself stupid, but somehow we individually intelligent humans are all managing to be stupid together.) This is the shit that is probably going to hit the fan first while we are shouting stupid slogans like “drill baby drill” (okay, if you are cheering when you hear a politician shout that you might not be stupid, but you are at least uninformed.)
- NOVEMBER: Ugh, the U.S. election. I don’t really want to talk or think too much more about it. What’s really frightening to me is the celebration of irrationality. With incompetent, irrational clowns and fools now in charge of everything, any crises or emergencies that arise are not going to be dealt with rationally, competently, or at all. And this is how an emergency can turn into a system failure. Let’s hope we can muddle through four years without a major acute crisis of some kind, but that is hard to do.
- DECEMBER: The annual “horizon scan” from the journal Trends in Ecology and Evolution lists three key issues having to do with tipping points: “melting sea ice, melting glaciers, and release of seabed carbon stores”.
Most hopeful stories
- JANUARY: According to Bill Gates, some bright spots in the world today include gains in administering vaccines to children around the world, a shift toward greater public acceptance of nuclear power, and maybe getting a bit closer to the dream of fusion power. He pontificates about AI, and my personal sense is it is still too soon, but AI does hold some promise for speeding up scientific progress.
- FEBRUARY: The people who are in charge of the USA’s nuclear weapons still believe in the ideals behind the founding of the country, at least more than the rest of us. Okay, this is lean times for hope, but seriously this at least buys us time to figure some stuff out.
- MARCH: Yes, there are some fun native (North American) wildflowers you can grow from bulbs. Let’s give the environmental and geopolitical doom and gloom a rest for a moment and cultivate our gardens.
- APRIL: Some tweaks to U.S. trade policy might be able to significantly ease the “border crisis” and create a broad political coalition of bigots, big business, and people who buy things in stores.
- MAY: The U.S. might manage to connect two large cities with true high speed rail, relatively soon and relatively cost effectively. The trick is that there is not much between these cities other than flat desert. The route will mostly follow an existing highway, and we should think about doing this more as autonomous vehicles very gradually start to reduce demand on our highways in coming decades.
- JUNE: Computer-controlled cars are slowly but surely attaining widespread commercial rollout. I don’t care what the cynics say – this will save land, money and lives. And combined with renewable and/or nuclear energy, it could play a big role in turning the corner on the climate crisis.
- JULY: A universal flu vaccine may be close, the same technology might work for other diseases like Covid, HIV, and tuberculosis.
- AUGUST: Drugs targeting “GLP-1 receptors” (one brand name is Ozempic) were developed to treat diabetes and obesity, but they may be effective against stroke, heart disease, kidney disease, Parkinson’s, Alzheimer’s, alcoholism, and drug addiction. They may even be miracle anti-aging drugs. But really, it seems like the simple story is that most of us in the modern world are just eating too much and moving our bodies too little, and these drugs might let us get some of the benefits of healthier lifestyles without actually making the effort. Making the effort, or making the effort while turbo-charging the benefits with drugs, might be the better option. Nonetheless, saving lives is saving lives.
- SEPTEMBER: AI should be able to improve traffic management in cities, although early ideas on this front are not very creative.
- OCTOBER: AI, at least in theory, should be able to help us manage physical assets like buildings and infrastructure more efficiently. Humans still need to have some up-front vision of what we would like our infrastructure systems to look like in the long term, but then AI should be able to help us make optimal repair-replace-upgrade-abandon decisions that nudge the system toward the vision over time as individual components wear out.
- NOVEMBER: In a nation of 350 million odd people, there have to be some talented potential leaders for us to choose between in future elections, right? Or is it clowns and fools all the way down? Sorry folks, this is how I feel.
- DECEMBER: I’m really drawing a blank on this one folks. Since I reviewed a number of book lists posted by others, I just pick one book title that sounds somewhat hopeful: Abolishing Fossil Fuels: Lessons from Movements That Won.
Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both
- JANUARY: The return of super-sonic commercial flight is inching closer.
- FEBRUARY: I am not a great chef by any means, but all hail recipe websites, however pesky they may be, for helping me make edible food.
- MARCH: I looked into Belarus, and now I am just a little bit less ignorant, which is nice.
- APRIL: If the singularity is in fact near, our worries about a productivity slow down are almost over, and our new worries will be about boredom in our new lives of leisure. It doesn’t seem like a good idea to count on this happening in the very near future, and therefore stop trying to solve the problems we have at the moment. This would be one of those “nice to have” problems. If it does in fact materialize, the places to be will be the ones that manage to shut down Peter Turchin’s wealth pump and spread the newfound wealth, rather than the places where a chosen few live god-like existences while leaving the masses in squalor.
- MAY: Drone deliveries make some sense, but what we really need is infrastructure on the ground that lets all sorts of slow, light-weight vehicles zip around in our cities efficiently and safely. And this means separating them completely from those fast, heavy vehicles designed for highway travel.
- JUNE: I had a misconception that if the world reduces greenhouse gases today, the benefits will not kick in for decades. Happily, scientists’ understanding of this has been updated and I will update my own understanding along with that. The key is the ocean’s ability to absorb excess carbon dioxide from the atmosphere relatively quickly. (I am not sure this is good for the ocean itself, but it is somewhat hopeful for temperatures here on land.) And it is not all or nothing – any emissions reductions will help, so the failure to act in the past is not an excuse to continue to fail to act.
- JULY: Maybe we could replace congress with AI agents working tirelessly on behalf of us voters. Or maybe we could just have AI agents tirelessly paying attention to what the humans we have elected are doing, and communicating in both directions.
- AUGUST: I did some musing about electric vehicles in August. The hype bubble seems to have burst a bit, as they did not explode onto the international commercial scene as some were hoping/predicting. This is partly because public infrastructure has not kept pace with the private sector due to sheer inertia, but I always detect a whiff of the evil oil/car industry propaganda and political capture behind the scenes. Nonetheless, just as I see happening with computer-driven vehicles, the technology and market will continue to develop after the hype bubble bursts. In a way, this almost starts the clock (5-10-20 years?) for when we can expect the actual commercial transition to occur. It will happen gradually, and one day we will just shrug, accept it, assume we knew it was coming all along, and eventually forget it was any other way. And since I seem to have transportation on the brain, here is a bonus link to my article on high speed trains.
- SEPTEMBER: Countries around the world update their constitutions about every 20 years on average. They have organized, legal processes for doing this spelled out in the constitutions themselves. The U.S. constitution is considered the world’s most difficult constitution to update and modernize.
- OCTOBER: Some explanations proposed for the very high cost of building infrastructure in the U.S. are (1) lack of competition in the construction industry and (2) political fragmentation leading to many relatively small agencies doing many relatively small projects. Some logical solutions then are to encourage the formation of more firms in the U.S., allow foreign firms and foreign workers to compete (hardly consistent with the current political climate!), and consolidate projects into a smaller number of much larger ones where economies of scale can be realized. There is some tension though between scale and competition, because the larger and more complex a project gets, the fewer bidders it will tend to attract who are willing to take the risk.
- NOVEMBER: You can charge moving electric vehicles using charging coils embedded in roads.
- DECEMBER: Bill Gates recommended The Coming Wave as the best recent book to understand the unfolding and intertwined AI and biotechnology revolution. I also listed the 2024 Nobel prizes, which largely had to do with AI and biotechnology.
Synthesis
Nuclear weapons and hypersonic missiles. The massive silver lining here is that, as I write this, there has been no use of nuclear weapons in war since 1945. Let’s hope it stays that way, forever and ever. But the expansion of nuclear arsenals among the existing powers, the open discussion of proliferation to new state actors, and the erosion of treaties and taboos on use of nuclear weapons are all deeply concerning. I find the hypersonic missiles particularly disturbing. These are being used in active, hot wars between nuclear powers – between Russia and NATO’s proxy Ukraine, and between Israel and Iran. We also hear that China has developed these weapons. Missiles are scary to begin with, but what is very, very scary is that these seem to be nuclear capable missiles and they are being actively used in hot wars between nuclear powers right now. If there are only a few minutes of warning when they are incoming, and they effectively can’t be pre-empted or intercepted, how does anyone know for sure that they are not nuclear armed before they hit their targets? So far, it seems like all sides are waiting for missiles to hit before we confirm they are not nuclear missiles. What if a state actor decides they can’t afford to wait and see and considers a pre-emptive strike? China and Iran have no-first-strike policies. The United States does not, and here is a fun fact – the SOVIET UNION had a no-first-strike policy, but modern Russia does not. Just to heap a little more sunshine on this topic, the rapid collapse of Syria, an aspiring nuclear power at one point, made me wonder if something similar could happen in Pakistan. And there is always the prospect of nuclear terrorism, particularly frightening when combined with extremist ideologies that glorify suicide and mass killing of civilians. It is easy to imagine horrible scenarios for all mankind on this one – but again, it is a risk that hasn’t materialized and can be managed. And it actually seems like a simpler, more tractable problem to me than complicated scenarios like climate change. Nuclear weapons are in the hands of relatively few leaders, and there is plenty of precedent for what arms control treaties and risk reduction measures can look like. Courageous leaders can step up on this issue – where are you guys?
Climate change. Let’s continue my little happy pep talk on existential threats. The climate change crisis is biting our civilization right now, and not only that, we are in the middle of it, not the beginning, and it is accelerating every day. This is the physical and socioeconomic reality, while our human civilization’s perception of reality let alone willingness and ability to act lag far behind. This is starting to feel like a story that will not and cannot end well. It is starting to bite our cities in the form of floods and fires, and this is well before relentless sea level rise really starts to bite in a significant way. Another place it will gradually start to bite harder, if it has not already, is food prices and eventually the physical food supply. As much as we have whined about food prices here in the U.S., the rise has been much worse in developing countries. And everything I just said is about the slow, steady, but relentless changes in the climate we have been experiencing and have to expect we will keep experiencing, at a minimum. The small piece of good news here is that if we took action immediately, we would start to see improvement in the trends immediately, rather than having to wait for some lag period to pass. My understanding of this has changed in the past year, and this is something positive. BUT what if rapid, sudden changes are in store? Some of the most terrifying articles I highlighted in 2024 have to do with tipping points, also known as runaway trains. We know about the accelerating melting glaciers and ice sheets, and how a sudden collapse of ice could lead to catastrophic and sudden sea level rise. We are seeing sudden rises in atmospheric methane concentrations – there seems to be some chance that this is the beginning of a feedback loop where frozen soil and seafloor sediments release methane bubbles as they thaw, which leads to more warming, which leads to more thawing, which leads to more warming and so on in a catastrophic exponential feedback loop that can’t be stopped on any time scale meaningful to humans. I hope we are not looking back a few years from now and concluding 2024 was the year that kicked this off. Now for some very small positive words – no matter how long our human political leaders dither and delay and fail, it is never too late to take actions that will make the outcome less bad than it could have been. Think about the reverse – if you were going to purposely try to make the situation as bad a possible, you could do things that would make it worse (like take all energy production back to coal). So past failure is never an excuse to stop trying, it is truly never too late to do better, even if our lack of effective action to date has closed off certain positive outcomes forever.
Bird flu. Continuing the doom and gloom theme, a major pandemic with a high mortality rate is clearly another existential threat we face. It could come from a natural source, a laboratory accident, or an intentional act. The risk of the latter will grow as biotechnology continues to progress and, unlike nuclear weapons, becomes more accessible to the masses. It’s like a major flood or earthquake. It will happen sooner or later. There are things we can do to limit the damage and to recover more quickly when it does happen, and we are probably not doing enough. The current strain of bird flu is concerning as it continues to devastate wild and domestic birds around the world, has spread extensively to domestic cows, there are some reports it has spread to pigs, and it has spread to some humans supposedly through direct contact with animals. Now having said all that, 2025 is probably not the year we get a devastating pandemic flu. Every year is probably not the year, because this is a low probability event in any given year that becomes highly probable over a long period of time. So the thing to do is stay calm and prepare. I actually have some hope that the vaccine technology that was rapidly scaled up and commercialized during Covid-19 will help us when the pandemic flu does hit. Let’s hope it’s not this year or any time during the next four years when we cannot expect to have competent leadership in the United States.
Artificial Intelligence. I suppose I have to say something about it. Well, I can’t recall in my lifetime any technology exploding exponentially into widespread commercial and public use in just over a year from its first announcement. You could almost describe it as…a singularity? Well not quite, but an ongoing exponential growth with no end in site, which is how a singularity would begin. Now, the downside is the sudden, massive, and completely unexpected energy demand this is causing, to the point that recently retired nuclear plants are being turned back on. I joked that AI might be the explanation for the Fermi paradox, where every civilization in the cosmos advanced enough to develop this technology wipes itself out by fouling its own nest when it tries to generate the energy required. I don’t believe this though – given that it’s easy to imagine an alternate history where nuclear fission based energy was scaled up in a serious way, and/or space based solar energy was scaled up in a serious way, and fusion based energy looking at least somewhat plausible, it does not seem like a foregone conclusion that we humans here on Earth had to foul our nest. This does not mean there is hope for us, it just means that there might be hope in a galaxy far, far away or in a billion of them too far away for us to see.
AI Agents. Now, as we foul our nest over the next few decades, there is the question of where AI goes in the next few months and years. And one big thing, I think, that is going to change our lives pretty quick is AI agents. We don’t really have AI going out and actively engaging in communications and transactions on our behalf on a large scale yet. But this has to be happening behind the scenes, and it has to happen in an obvious public way pretty soon. Imagine if I asked an AI to keep track of what one of my elected representatives is doing each day, read and summarize legislation they vote for or against, and just explain it to me in an easily digestible way for five minutes a day. Now imagine my AI is talking to my representative’s AI, and everyone else’s AIs are doing that, and giving the AI a summary of what all these AIs are thinking. That sounds pretty democratic right? But now imagine AIs from companies and governments are trying to manipulate all of us to buy things and believe things and do things they want us to do. Now imagine ALL THESE AIs ARE TALKING AND TRANSACTING WITH EACH OTHER, ALL THE TIME, AND THEY NEVER GET TIRED OR NEED A BREAK. It gets dizzying pretty quick.
Competing Feedback Loops. AI has definitely increased my personal productivity in writing computer programs and communicating the results in the past year. This must be happening on a large scale, at least it certain types of jobs. On the other hand, the IMF tells us worldwide productivity has slowed down since the 2009 financial crisis and was made worse by the Covid-19 crisis. There are also continuing headwinds like aging populations and falling fertility rates in many developed countries. How can both these things be true, an acceleration of productivity and a slowdown of productivity? The way I think about it, they are competing feedback loops, kind of like the faucet in your bathtub being on while at the same time there is no drain plug. Whether your tub is filling up or draining down depends on the relative strength of the positive and negative feedback loops. And unlike your bathtub, both are changing in time and subject to random shocks. So it could go either way – civilization could be going down the drain, the technological singularity might be imminent, or the two could be close to balance so it seems like nothing is happening for a long time, until one of them gets the upper hand. These are not the only feedback loops of course – the ongoing climate and biodiversity crises are also in the mix and since these are negative, we have to really hope that AI faucet is wide open, or find a stopper for the drain, or some combination of the two. We don’t have many world leaders working on the stopper thing right now, many are trying to drill baby drill an even bigger hole.
Biotechnology. AI seems likely to accelerate the progress of biotechnology, leading toward both medical breakthroughs (universal vaccines, cures for cancer and diabetes) and increasing risks of accidents and terrorism. Its hard to predict when these things will hit the news – progress is slow and steady for a long time, and then a technology will seem to burst onto the public scene all at once. Sometimes there is a big hype bubble that reaches a peak and seems to explode, and then while the public assumes the technology is dead, the slow and steady progress toward widespread commercialization resumes and eventually takes hold of the entire system. And then we shrug, forget the past, and assume we knew it was coming all along.
Electric Vehicles and Autonomous Vehicles. The U.S. government might be throwing up some headwinds to technological progress (i.e., doing their best to usher in a dark age not a “golden age”), but the global socioeconomic and scientific systems that drive technological progress are much too big to be constrained by the U.S. government. While many in the U.S. may have the impression that the electric vehicle revolution has stalled, it is forging ahead in Asia and around the world. China is building cars for $10,000, and nobody else (Japan, Korea, or Tesla let alone Detroit) can figure out how to compete with this. I suspect one driver of the protectionist impulse in the U.S. is fear that we have no chance of competing, so our government is willing to imprison us in a bubble of outdated technology at uncompetitive prices, and if they can’t outright restrict information about the outside world from getting in, they will use propaganda to distort that information so we don’t understand what we are missing. It’s like the Soviet Union, or worse, North Korea. We are certainly not as far behind as the Soviet Union or North Korea relative to our peers yet, but this is the path we are headed down. Similarly to electric vehicles, we are hearing from our media that autonomous vehicle technology has stalled or under-delivered or is risky (it’s not, by any rational measure compared to the massive death and suffering caused by human-driven vehicles). But this technology has in fact arrived, just arrived unevenly in certain cities in the U.S. and around the world, and our government policy is slowing its spread for example with policies that do not allow autonomous vehicles on highways. These two technologies – electric and autonomous vehicles – have to combine and reinforce each other sooner or later, and this will change a lot of things about how our cities and infrastructure are configured in the future. It’s hard to give a timetable, but I bet if you go to a leading edge city in China, Korea, or Japan a decade from now these technologies will be everywhere and it will seem like science fiction to a U.S. traveler who has been kept in the dark about the state of the outside world as our once world-leading country has stagnated.
Inequality and the Wealth Pump. I hadn’t heard the term “wealth pump” before reading Peter Turchin in 2024, but it rings true. Wealth and income inequality is just the elephant in the room behind the 2024 U.S. election and many other geopolitical trends around the world. It is getting worse in the U.S., and it is not going to get better as long as the wealthy and powerful are able to continue rigging the rules of the system more and more in their favor. The pain of the masses is very real. And Donald Trump may have found rhetoric that taps into this pain, but his administration is certainly not going to make the situation better. But nor has the Democratic Party shown any signs of making the situation better. They may tinker with some marginal policy changes that slow the trend (for example, the short-lived increase in tax credits to offset childcare expenses, some steps to slow the rise of prescription drug prices) but do not reverse it (for example, creating real childcare, education, and health care benefits that reach the vast majority of working citizens). Bernie Sanders is the only U.S. politician who has spoken authentically to the people about these issues in recent memory, and he reached a lot of people although not quite enough when the established Democratic Party did everything they could to sabotage him. There is also the problem of half a century of very effective anti-tax propaganda that is very hard to overcome. But still, I believe Bernie showed us the way. The Democrats need to embrace the man and his policies, and find him a true protege or several to choose from who are able to speak with his authenticity and maybe a bit more youth and charisma. Trump is all but guaranteed to fuck up massively over the next four years, so the question is will the Democrats let his propaganda machine convince us to blame scapegoats or will they be ready?
Government of the Fools, By the Fools, For the Fools, and Where’s Waldo? Before January 20, 2025 it was clear to me that the U.S. will be governed by fools and amateurs for the next four years. And this alone is sad because it will lead to our continued stagnation and at least relative decline while peer countries are moving into the future. It is also dangerous because the nation might be able to muddle through while there is nothing unusual going on, but fools, amateurs and clowns are not going to prepare or respond effectively to emergencies, disasters, and unexpected events. Four years is a long enough time that some unexpected events should be expected. We can only hope they are not too far out in the tails. But as I write this on January 23, 2025, it seems even worse. Trump is a fool, but a very powerful and dangerous fool, and at least some of the people whispering in his ear are evil cruel-hearted psychopaths, sadists, and outright devils. I don’t think Trump is Hitler, because Hitler believed in things (evil, twisted things) whereas I think Trump is a pure psychopath who believes in nothing and is willing to say or do anything he thinks will increase his own power. But who are the Heydrichs, Himmlers, and Goebbels among his supporters? I am not sure, but whoever they are they are hiding in plain site in a crowd of clowns and fools where they are hard to pick out. It’s time to play a little Where’s Waldo.
Welcome to 2025!
And that is all the sunshine and light I have to offer you here in this January 2025. If you are a human being reading this in close to real time, happy 2025 and may it be better than expected, which is not a high bar at all! If you are an alien archaeologist reading this in the far future, I hope it helps you make sense of the rubble of our civilization. If you are a transhuman reading it after the singularity in the near future (I heard October 2029 according to Ray Kurzweil’s latest prediction?), I hope you are laughing that the problems that seemed so dire to me in January 2025 had solutions just around the corner!
Trends in Ecology and Evolution Horizon Scan
Trends in Ecology and Evolution has released their annual horizon scan. Here is their list of issues:
- Greater biological risks from nocturnal, near-surface level ozone
- Metal and non-metal organic frameworks
- Macroalgae as a new source of critical rare earth elements
- Emerging techniques for remediating per- and polyfluoroalkyl contamination
- Adhesive trichome hair mimics as alternatives to pesticides
- Synthetic gene drives in plants
- Light evaporating water without heat
- Low emission cement recycling
- Impacts of near-magma geothermal drilling
- Compounded effects of water quality and quantity on human and natural systems
- European laws and unintended challenges for wood production
- Record Antarctic sea ice lows across the continent could lead to large-scale ecosystem alterations
- Faster than predicted melting of Thwaites glacier
- Anthropogenic impacts on seabed carbon stores
- Potential alteration of ocean processes by offshore wind energy infrastructure
There are at least three issues here having to do with feedback loops and tipping points: melting sea ice, melting glaciers, and release of seabed carbon stores. When we look back, is 2024 going to be the year tipping points were passed and runaway feedback loops got out of control? I don’t know, but we should behave as if it is since the consequences are so dire. Then if we actually have a few more years or even decades before the historical climate system is truly irretrievable, so much the better and we will have gotten ahead of the curve. What do we actually have in the United States – inaction and brainless, asinine slogans like “drill baby drill!”.
And then there’s the water situation. It’s just not great, particularly with the amount of nitrogen we are continuing to dump into the ocean.
increase in atmospheric methane in 2020-2022 was “highest on record”
This has only been measured for a few decades, but a detectable increase in the rate of increase in atmospheric methane made me think of tipping points. Could the much-to-be-feared feedback loops in permafrost and methane hydrates thawing be underway right now?
This article doesn’t mention either permafrost or hydrates. It does say that the increases are not a result of leaking natural gas wells or any other fossil fuel industry site. They narrow the cause down to “sources such as wetlands, waste, and agriculture”. I supposed some frozen wetlands could be thawing out, but it seems like the article would have mentioned that. I am skeptical that there has been any drastic worldwide change in landfill operations. A big change in agricultural practices – this could be plausible, I don’t know enough to say it is not.
11 square miles of moss
11 square miles covered with moss since 1986 just doesn’t sound all that dramatic to me, but apparently for Antarctica this is a big deal and not a good sign. Apparently it has been happening for awhile in (originally sarcastically named?) Greenland, and it is not as big of a surprise there, but it is still not a good sign.
North Atlantic sea surface temperature anomaly
This year’s ocean temperatures are being described as “unprecedented”, “off the charts”, and “beyond extreme”. I have to stare at this plot for awhile to get it, but basically the 0 line is the long-term average, presumably over 50 years or so. Then each individual line shows the difference between actual temperature and that average, for one year, over the course of the year. So not only is the departure of more than 1.5 C in June 2023 way above the average, it is way above any other extremes seen over the last 50 years.

The article gives physical explanations, including El Nino, changes in ocean currents, and changes in wind currents. It says climate change is a factor but doesn’t really reach conclusions on how much of a factor. I think it almost certainly has to be a factor. But the important question to me is whether this is an extreme fluctuation the likes of which we are going to start seeing occasionally, or the start of some runaway trend we are going to start seeing frequently and may even get worse? The article does not suggest anything like the latter. Tipping points concern me – could this be an early warning that we have hit some tipping point in terms of runaway methane release for example? The article doesn’t suggest that. Let’s hope not. If it is, it would be an “unprecedented” planetary emergency and we would need to pull out the stops and try any and all of those risky geoengineering ideas we have been hearing about, because “risky” is by definition less risky than “certain doom”. Let’s hope not. The fluctuation does appear to be subsiding, so we can see where we are next year around this time.
2021: Year in Review
As per usual, I’ll list out and link to the stories I chose as the most frightening, most hopeful, and most interesting each month in 2021. Then I’ll see if I have anything smart to say about how it all fits together.
Survey of the Year’s Stories and Themes
Most frightening and/or depressing stories:
- JANUARY: A China-Taiwan military conflict is a potential start-of-World-War-III scenario. This could happen today, or this year, or never. Let’s hope for the latter. This is a near-term existential risk, but I have to break my own “rule of one” and give honorable mention to two longer-term scary things: crashing sperm counts and the climate change/fascism/genocide nexus.
- FEBRUARY: For people who just don’t care that much about plants and animals, the elevator pitch on climate change is it is coming for our houses and it is coming for our food and water.
- MARCH: In the U.S. upper Midwest (I don’t know if this region is better or worse than the country as a whole, or why they picked it), electric blackouts average 92 minutes per year, versus 4 minutes per year in Japan.
- APRIL: One of the National Intelligence Council’s scenarios for 2040 involves “far-reaching changes designed to address climate change, resource depletion, and poverty following a global food catastrophe caused by climate events and environmental degradation”.
- MAY: The Colorado River basin is drying out.
- JUNE: For every 2 people who died of Covid-19 in the U.S. about 1 additional person died of indirect effects, such as our lack of a functioning health care system and safe streets compared to virtually all our peer countries.
- JULY: The western-U.S. megadrought looks like it is settling in for the long haul.
- AUGUST: The U.S. is not prepared for megadisasters. Pandemics, just to cite one example. War and climate change tipping points, just to cite two others. Solutions or at least risk mitigation measures exist, such as getting a health care system, joining the worldwide effort to deal with carbon emissions, and as for war, how about just try to avoid it?
- SEPTEMBER: The most frightening climate change tipping points may not be the ones we hear the most about in the media (at least in my case, I was most aware of melting ice sheets in Greenland and Antarctica, collapse of ocean circulation patterns). The most damaging may be melting permafrost on land and methane hydrates underwater, both of which contain enormous amounts of methane which could set off a catastrophic and unstoppable feedback loop if released in large quantities.
- OCTOBER: The technology (sometimes called “gain of function“) to make something like Covid-19 or something much worse in a laboratory clearly exists right now, and barriers to doing that are much lower than other types of weapons. Also, because I just couldn’t choose this month, asteroids can sneak up on us.
- NOVEMBER: Freakonomics podcast explained that there is a strong connection between cars and violence in the United States. Because cars kill and injure people on a massive scale, they led to an expansion of police power. Police and ordinary citizens started coming into contact much more often than they had. We have no national ID system so the poor and disadvantaged often have no ID when they get stopped. Everyone has guns and everyone is jumpy. Known solutions (safe street design) and near term solutions (computer-controlled vehicles?) exist, but are we going to pursue them as a society? I guess I am feeling frightened and/or depressed today, hence my choice of category here.
- DECEMBER: Mass migration driven by climate change-triggered disasters could be the emerging big issue for 2022 and beyond. Geopolitical instability is a likely result, not to mention enormous human suffering.
Most hopeful stories:
- JANUARY: Computer modeling, done well, can inform decisions better than data analysis alone. An obvious statement? Well, maybe to some but it is disputed every day by others, especially staff at some government regulatory agencies I interact with.
- FEBRUARY: It is possible that mRNA technology could cure or prevent herpes, malaria, flu, sickle cell anemia, cancer, HIV, Zika and Ebola (and obviously coronavirus). With flu and coronavirus, it may become possible to design a single shot that would protect against thousands of strains. It could also be used for nefarious purposes, and to protect against that are ideas about what a biological threat surveillance system could look like.
- MARCH: I officially released my infrastructure plan for America, a few weeks before Joe Biden released his. None of the Sunday morning talk shows has called me to discuss so far. Unfortunately, I do not have the resources of the U.S. Treasury or Federal Reserve available to me. Of course, neither does he unless he can convince Congress to go along with at least some portion of his plans. Looking at his proposal, I think he is proposing to direct the fire hoses at the right fires (children, education, research, water, the electric grid and electric vehicles, maintenance of highways and roads, housing, and ecosystems. There is still no real planning involved, because planning needs to be done in between crises and it never is. Still, I think it is a good proposal that will pay off economically while helping real people, and I hope a substantial portion of it survives.
- APRIL: Giant tortoises reach a state of “negligible senescense” where they simply don’t age for a long time. Humans are distant relatives of giant tortoises, so maybe we can aspire to this some day. They are not invulnerable to injury and disease.
- MAY: An effective vaccine for malaria may be on the way. Malaria kills more children in Africa every year than Covid-19 killed people of all ages in Africa during the worst year of the pandemic. And malaria has been killing children every year for centuries and will continue long after Covid-19 is gone unless something is done.
- JUNE: Masks, ventilation, and filtration work pretty well to prevent Covid transmission in schools. We should learn something from this and start designing much healthier schools and offices going forward. Design good ventilation and filtration into all buildings with lots of people in them. We will be healthier all the time and readier for the next pandemic. Then masks can be slapped on as a last layer of defense. Enough with the plexiglass, it’s just stupid and it’s time for it to go.
- JULY: A new Lyme disease vaccine may be on the horizon (if you’re a human – if you are a dog, talk to your owner about getting the approved vaccine today.) I admit, I had to stretch a bit to find a positive story this month.
- AUGUST: The Nordic welfare model works by providing excellent benefits to the middle class, which builds the public and political support to collect sufficient taxes to provide the benefits, and so on in a virtuous cycle. This is not a hopeful story for the U.S., where wealthy and powerful interests easily break the cycle with anti-tax propaganda, which ensure benefits are underfunded, inadequate, available only to the poor, and resented by middle class tax payers.
- SEPTEMBER: Space-based solar power could finally be in our realistic near-term future. I would probably put this in the “interesting” rather than “hopeful” category most months, but I really struggled to come up with a hopeful story this month. I am at least a tiny bit hopeful this could be the “killer app” that gets humanity over the “dirty and scarce” energy hump once and for all, and lets us move on to the next layer of problems.
- OCTOBER: The situation with fish and overfishing is actually much better than I thought.
- NOVEMBER: Urban areas may have some ecological value after all.
- DECEMBER: Covid-19 seems to be “disappearing” in Japan, or at least was before the Omicron wave. Maybe lessons could be learned. It seems possible that East Asian people have at least some genetic defenses over what other ethnic groups have, but I would put my money on tight border screening and an excellent public health care system. Okay, now I’m starting to feel a bit depressed again, sitting here in the U.S. where we can’t have these nice things thanks to our ignorant politicians.
Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both:
- JANUARY: There have been fabulous advances in note taking techniques! Well, not really, but there are some time honored techniques out there that could be new and beneficial for many people to learn, and I think this is an underappreciated productivity and innovation skill that could benefit people in a lot of areas, not just students.
- FEBRUARY: At least one serious scientist is arguing that Oumuamua was only the tip of an iceberg of extraterrestrial objects we should expect to see going forward.
- MARCH: One study says 1-2 days per week is a sweet spot for working from home in terms of a positive economic contribution at the national scale. I think it is about right psychologically for many people too. However, this was a very theoretical simulation, and other studies attempting to measure this at the individual or firm scale have come up with a 20-50% loss in productivity. I think the jury is still out on this one, but I know from personal experience that people need to interact and communicate regularly for teams to be productive, and some people require more supervision than others, and I don’t think technology is a perfect substitute for doing these things in person so far.
- APRIL: Hydrogen fuel cells may finally be arriving. Not so much in the U.S., where we can’t have nice things.
- MAY: I learned about Lawrence Kohlberg, who had some ideas on the use of moral dilemmas in education.
- JUNE: The big U.S. government UFO report was a dud. But what’s interesting about it is that we have all quietly seemed to have accepted that something is going on, even if we have no idea what it is, and this is new.
- JULY: “Cliodynamics” is an attempt at a structured, evidence-based way to test hypotheses about history.
- AUGUST: Ectogenesis is an idea for colonizing other planets that involves freezing embryos and putting them on a spaceship along with robots to thaw them out and raise them. Fungi could also be very useful in space, providing food, medicine, and building materials.
- SEPTEMBER: Philip K. Dick was not only a prolific science fiction author, he also developed a comprehensive theory of religion which could possibly even be the right one. Also, possibly related but not really, if there are aliens out there they might live in creepy colonies or super-organisms like ants or termites.
- OCTOBER: I thought about how to accelerate scientific progress: “[F]irst a round of automated numerical/computational experiments on a huge number of permutations, then a round of automated physical experiments on a subset of promising alternatives, then rounds of human-guided and/or human-performed experiments on additional subsets until you hone in on a new solution… [C]ommit resources and brains to making additional passes through the dustbin of rejected results periodically…” and finally “educating the next generation of brains now so they are online 20 years from now when you need them to take over.” Easy, right?
- NOVEMBER: Peter Turchin continues his project to empirically test history. In this article, he says the evidence points to innovation in military technologies being driven by “world population size, connectivity between geographical areas of innovation and adoption, and critical enabling technological advances, such as iron metallurgy and horse riding“. What does not drive innovation? “state-level factors such as polity population, territorial size, or governance sophistication“. As far as the technologies coming down the pike in 2022, one “horizon scan” has identified “satellite megaconstellations, deep sea mining, floating photovoltaics, long-distance wireless energy, and ammonia as a fuel source”.
- DECEMBER: Time reminded us of all the industries Elon Musk has disrupted so far: human-controlled, internal-combustion-fueled automobiles; spaceflight; infrastructure construction (I don’t know that he has really achieved any paradigm shifts here, but not for lack of trying), “artificial intelligence, neurotechnology, payment systems and cryptocurrency.” I’m not sure I follow a couple of these, but I think they missed satellites.
Continuing Signs of U.S. Relative Decline
Signs of U.S. decline relative to our peer group of advanced nations are all around us. I don’t know that we are in absolute decline, but I think we are now below average among the most advanced countries in the world. We are not investing in the infrastructure needed in a modern economy just to reduce friction and let the economy function. The annual length of electric blackouts in the U.S. (hours) compared to leading peers like Japan (minutes) is just one telling indicator. In March, I looked at the Build Back Better proposal and concluded that it was more like directing a firehose of money at a range of problems than an actual plan, but I hoped at least some of it would happen. My rather low but not zero expectations were met, as some limited funding was provided for “hard infrastructure” and energy/emissions projects, but little or nothing (so far, as I write this) to address our systemic failures in health care, child care, or education. The crazy violence on our streets, both gun-related and motor vehicle-related, is another indicator. Known solutions to all these problems exist and are being implemented to various extents by peer countries. Meanwhile our toxic politics and general ignorance continue to hold us back. Biden really gave it his best shot – but if this is our “once in a generation” attempt, we are headed down a road where we will no longer qualify as a member of the pack of elite countries, let alone its leader.
The Climate Change, Drought, Food, Natural Disaster, Migration and Geopolitical Instability Nexus
2021 was a pretty bad year for storms, fires, floods, and droughts. All these things affect our homes, our infrastructure, our food supply, and our water supply. Drought in particular can trigger mass migration. Mass migration can be a disaster for human rights and human dignity in and of itself, and managing it effectively is difficult even for well-intentioned governments. But an insidious related problem is that migration pressure can tend to fuel right wing populist and racist political movements. We see this happening all over the world, and the situation seems likely to get worse.
Tipping Points and other Really Bad Things We Aren’t Prepared For
We can be thankful that nothing really big and new and bad happened in 2021. My apologies to anyone reading this who lost someone or had a tough year. Of course, plenty of bad things happened to good people, and plenty of bad things happened on a regional or local scale. But while Covid-19 ground on and plenty of local and regional-scale natural disasters and conflicts occurred, there were no new planetary-scale disasters. This is good because humanity has had enough trouble dealing with Covid-19, and another major disaster hitting at the same time could be the one that brings our civilization to the breaking point.
So we have a trend of food insecurity and migration pressure creeping up on us over time, and we are not handling it well even given time to do so. Maybe we can hope that some adjustments will be made there to get the world on a sustainable track. Even if we do that, there are some really bad things that could happen suddenly. Catastrophic war is an obvious one. A truly catastrophic pandemic is another (as opposed to the moderately disastrous pandemic we have just gone through.) Creeping loss of human fertility is one that is not getting much attention, but this seems like an existential risk if it were to cross some threshold where suddenly the global population starts to drop quickly and we can’t do anything about it. Asteroids were one thing I really thought we didn’t have to worry much about on the time scale of any human alive today, but I may have been wrong about that. And finally, the most horrifying risk to me in the list above is the idea of an accelerating, runaway feedback loop of methane release from thawing permafrost or underwater methane hydrates.
We are almost certainly not managing these risks. These risks are probably not 100% avoidable, but since they are existential we should be actively working to minimize the chance of them happening, preparing to respond in real time, and preparing to recover afterward if they happen. Covid-19 was a dress rehearsal for dealing with a big global risk event, and humanity mostly failed to prepare or respond effectively. We are lucky it was one we should be able to recover from as long as we get some time before the next body blow. We not only need to prepare for much, much worse events that could happen, we need to match our preparations to the likelihood of more than one of them happening at the same time or in quick succession.
Technological Progress
Enough doom and gloom. We humans are here, alive, and many of us are physically comfortable and have much more leisure time than our ancestors. Our social, economic, and technological systems seem to be muddling through from day to day for the time being. We have intelligence, science, creativity, and problem solving abilities available to us if we choose to make use of them. Let’s see what’s going on with technology.
Biotechnology: The new mRNA technology accelerated by the pandemic opens up potential cures for a range of diseases. We need an effective biological surveillance system akin to nuclear weapons inspections (which we also need) to make sure it is not misused (oops, doom and gloom trying to creep in, but there are some ideas for this.) We have vaccines on the horizon for diseases that have been plaguing us for decades or longer, like malaria and Lyme disease. Malaria kills more children worldwide, year in and year out, than coronavirus has killed per year at its peak.
Promising energy technologies: Space based solar power may finally be getting closer to reality. Ditto for hydrogen fuel cells in vehicles, although not particularly in the U.S. (I’m not sure this is preferable to electric vehicles for everyday transportation, but it seems like a cleaner alternative to diesel and jet fuel when large amounts of power are needed in trucking, construction, and aviation, for example.)
Other technologies: We are actually using technology to catch fish in more sustainable ways, and to grow fish on farms in more sustainable ways. We are getting better at looking for extraterrestrial objects, and the more we look, the more of them we expect to see (this one is exciting and scary at the same time). We are putting satellites in orbit on an unprecedented scale. We have computers, robots, artificial intelligence of a sort, and approaches to use them to potentially accelerate scientific advancements going forward.
The State of Earth’s Ecosystems
The state and trends of the Earth’s ecosystems continue to be concerning. Climate change continues to churn through the public consciousness and our political systems, and painful as the process is I think our civilization is slowly coming to a consensus that something is happening and something needs to be done about it (decades after we should have been able to do this based on the evidence and knowledge available.) When it comes to our ecosystems, however, I think we are in the very early stages of this process. This is something I would like to focus on in this blog in the coming year. My work and family life are busy, and I have decided to take on an additional challenge of becoming a student again for the first time in the 21st century, but somehow I will persevere. If you are reading this shortly after I write it in January 2022, here’s to good luck and prosperity in the new year!
September 2021 in Review
Most frightening and/or depressing story: The most frightening climate change tipping points may not be the ones we hear the most about in the media (at least in my case, I was most aware of melting ice sheets in Greenland and Antarctica, collapse of ocean circulation patterns). The most damaging may be melting permafrost on land and methane hydrates underwater, both of which contain enormous amounts of methane which could set off a catastrophic and unstoppable feedback loop if released in large quantities.
Most hopeful story: Space-based solar power could finally be in our realistic near-term future. I would probably put this in the “interesting” rather than “hopeful” category most months, but I really struggled to come up with a hopeful story this month. I am at least a tiny bit hopeful this could be the “killer app” that gets humanity over the “dirty and scarce” energy hump once and for all, and lets us move on to the next layer of problems.
Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both: Philip K. Dick was not only a prolific science fiction author, he also developed a comprehensive theory of religion which could possibly even be the right one. Also, possibly related but not really, if there are aliens out there they might live in creepy colonies or super-organisms like ants or termites.
tipping points
A new article from Proceedings of the National Academy of Sciences goes through eight climate change tipping points that have studied, and tries to assign an economic impact to each. I’ll list them here in order of highest to lowest impact according to this study (see Table 2). They use the change in social cost of carbon as their key metric.
Two tipping points have major potential impacts and represent over 80% of the total risk from the eight, according to this study:
- ocean methane hydrates
- permafrost carbon feedback
Four tipping points have relatively modest expected impacts, at least modest compared to the truly existential threats represented by the top two:
- West Antarctic Ice Sheet
- Greenland Ice Sheet disintegration
- Indian Summer Monsoon
- Amazon dieback
Finally, two actually have small positive impacts on the (human) economy according to these authors:
- Atlantic Meridional Overturning Circulation slowdown (AMOC)
- Arctic sea ice / Surface Albedo Feedback
They don’t include “nonmarket effects”, so if you just feel that the death of the Amazon forest is profoundly sad, that is not reflected here. The authors are explicit about this so I guess it is okay.
These results are mismatched with my impressions, which are most likely driven by the amount of media coverage given to tipping points. I have probably read the most about ice sheets, the AMOC, and the Amazon, and these somewhat surprisingly do not make the top of the list. I feel like I have some basic grasp of the scientific concepts on each of these other than the methane hydrates. I understand why releasing massive amounts of methane would raise temperatures. I just don’t yet understand the feedback loop that would cause it to happen, whereas with the permafrost thawing it is pretty clear. Are the methane hydrates just frozen and expected to melt? I suppose in that case they are very similar to methane under the permafrost, with the difference being land and water. So the release of vast amounts of trapped methane is by far the biggest impact identified by this paper. For the most part though, the solutions to address any of these tipping points are going to be the same – drastic greenhouse gas emissions reductions and/or drastic geoengineering. Nothing else is going to reduce the amount of heat and solar energy melting ice, thawing permafrost and undersea frozen methane hydrates, and affecting ocean currents across vast chunks of the planet.
Hothouse Earth
This is the Hothouse Earth paper, which supposedly got media coverage last week that I completely missed despite scanning the media daily for articles on exactly this sort of topic. It argues that one or more tipping points leading to catastrophic feedback loops are looking increasingly likely if we exceed the 2 degrees C. So yes, we really need to get serious about not exceeding the 2 degrees C. But don’t worry, solutions exist! We need only take simple steps such as “decarbonization of the global economy, enhancement of biosphere carbon sinks, behavioral changes, technological innovations, new governance arrangements, and transformed social values.”
