Increased carbon dioxide concentrations have spurred plant growth up to a point, but at the same time increased temperatures have led to increased evaporation and transpiration (evaporation of water from plants to the atmosphere). The net result, if I understand this article in Science correctly, is that the drying effect now more than offsets the increased carbon uptake effect, so the growth rate of plants is no longer increasing as carbon dioxide concentrations increase.
Maui
The Maui fires are awful. First of all, my sympathy for all the loss of life, property, and all the displacement and disruption people are experiencing. The Los Angeles Times has some coverage of factors that may have contributed to the disaster.
- Rain shadow and seasonal dry conditions, which are normal
- Severe drought on top of these conditions
- Low humidity
- High winds (gusts up to 80 mph) caused by a hurricane nearby, but not close enough to cause rainfall on the island
- High ocean temperatures made even worse by El Nino this year
The severity and frequency of both drought and hurricanes have increased due to climate change, making this catastrophic combination of factors more likely to occur than it would have been in the past. The article also says cooler ocean temperatures in the past have tended to steer hurricanes away from Hawaii, and this is also less like to occur now than in the past. So all this is bad luck, but we humans have made our own bad luck to a certain extent.
What is Obama up to?
According to this rambling article, he has houses in Hawaii (Oahu), Hyde Park (I’m assuming Chicago, not New York or London?), Martha’s Vineyard, and the Kalorama development inside Washington D.C. The latter is popular with current and ex-government types, celebrities, diplomats, and captains of industry. Some conspiracists believe he is running a “shadow government” from this location, and for this the offer two points of evidence: (1) He is a retired career politician who still lives in Washington, D.C. at least some times and (2) higher ups in the current administration are sometimes spotted at his house. This seems pretty weak to me. His house seems like a convenient place to have an offsite meeting where you would already have the maximum possible security presence and you might get some free advice from the former leader of the free world in the bargain. Giving take-it-or-leave-it advice would not be “running a shadow government”. Doing some fundraising and persuading at the request of the current party leadership would not be “running a shadow government”. So I don’t know but it seems unlikely.
There’s also some gobbledygook about Ukraine in the article. The only real data points we have on that are that (1) Obama instinctively opposed Hillary Clinton’s push for more or less unprovoked war on Libya (although he gave in), (2) he offered Ukraine only non-lethal aid following the invasion of Crimea, and (3) he supported the Minsk peace accord. We can only speculate now whether Russia would have invaded Ukraine under a Hillary Clinton administration, although I think they were scared enough of her that it may have motivated them to interfere with the 2016 U.S. election (after the U.S. almost certainly interfered in the 2014 Ukraine election, at least in terms of propaganda.) If they had, we can only speculate whether she would have responded with a no-fly zone or some other Cuban Missile Crisis level gamble. I think she might have. Now we need to look ahead and consider whether a second Trump administration will just give up the farm and allow Ukraine to be partitioned or conquered outright.
Are humans a cancer on the planet?
This is the premise of Warren Hern in a new book called Homo Ecophagus: A Deep Diagnosis to Save the Earth.
The basic premise is that humans have the capacity of developing culture, and that has millions of manifestations, everything from language and speech and mathematics to constructing shelters, building weapons and having medical care to keep us alive. These adaptations have allowed us to go from a few separate species of skinny primates wandering around in Africa a couple of million years ago to being the dominant ecological force on the planet to the point we’re changing the entire global ecosystem…
These cultural adaptations have now become maladaptive. They do not have survival value. And they are, in fact, malignant maladaptations because they’re increasing in a way that cancer increases. So, this means that the human species now has all of the major characteristics of a malignant process. When I was in medical school, we had four of them that were identified: rapid, uncontrolled growth; invasion and destruction of adjacent normal tissues — in this case, ecosystems; metastasis, which means distant colonization; and dedifferentiation, which you see very well in the patterns of cities.

I don’t want to believe this. We know the universe is ultimately tending to random disorder. Somehow, physical forces are able to buck this trend and create small pockets of order like stars, planets, solar systems, and complex chemical compounds. And then on only one planet that we know of in all the universe, something called life has arisen from these chemical compounds, which has an extraordinary ability to construct ordered systems in our random universe. And then in only one species we know of in all the universe, something called intelligence has arisen from that life with the ability to create hitherto unimagined complex ordered systems. I don’t want to believe that this process has come to its conclusion and that the conclusion is one that ends the entire forward progression forever. Of course, if we are not the only intelligent life in the universe and if intelligent life is in fact common, then the situation looks much less bleak. Our particular malignant form of intelligent life can destroy its host and thus itself, and in fact this can happen in the vast majority of cases, but somebody somewhere can carrying on with the project of creating order and beauty in a cold indifferent universe. This, in my view, is the meaning and purpose of life. It just isn’t looking at the moment like we will be the ones to do it. And if in defiance of all reason we are the only intelligent life that has arisen or ever will arrive in the universe, then the future is an eternity of cold indifference, and we will be the ones who blew it.
remote work, productivity, and lazy kids today
I think this Fortune article (paywalled, but I was able to read it the first time I clicked) drawing conclusions about remote work based on productivity statistics is off base. Labor productivity, as I understand it, is dollars changing hands in the economy divided by hours people say they worked. There are a number of measurement problems here. First, in the short term it is just going to fluctuate with dollars changing hands, which fluctuates for all sorts of reasons, so it makes more sense to look at longer-term averages. Second, dollars changing hands is not a perfect measure of value – we could be paying the same number of dollars for crappier goods and services as our expectations are gradually lowered over time. I really suspect this is what is happening.
It does make sense to me that self-reported hours worked at home would be less productive. Even if most people are honest most of the time, some people are going to be less honest some of the time than they would be in an office. People are going to be more distracted. But in all these cases, they are going to report the same number of hours worked and get paid the same number of dollars they would have in the office. So there will be no effect on calculated productivity, while we get used to gradually shifting baseline of crappier goods and services over time.
I think another effect is that training and onboarding are getting harder in some sorts of jobs. Some jobs have a playbook telling a worker exactly what to do, but many jobs do not. In my field of engineering, there is not much of a playbook because we are often trying to apply existing knowledge to solve novel problems under changing external conditions. I learned this job in the 1990s and 2000s by spending a lot of extra time in the office at the end of the day shooting the breeze with colleagues, mentors, and clients. Somewhat frequently, someone would suggest moving these sessions to a local drinking establishment and they would go well into the evening. This was not necessarily healthy for work-life balance or for my liver and waistline, but it’s an important part of how I learned my job and industry and why I am good at it today. This time didn’t go on my time sheet, and yet it boosts my subjectively measured productivity today.
I don’t want to complain about today’s crop of young people, who are just as intelligent as my generation (perhaps more since they’ve been exposed to less lead and air pollution) and seem to have better health habits overall. But the combination of working from home, less informal interaction with mentors, and job hopping means it is much harder for them to learn to do jobs really well. In decade, they will be the ones doing most of the work and trying to train the generation under them, and again we will just get a gradually shifting baseline of lower expectations and worse outcomes, even if we may not be measuring that effectively in dollars.
July 2023 in Review
Most frightening and/or depressing story: Citizens United. Seriously, this might be the moment the United States of America jumped the shark. I’ve argued in the past or Bush v. Gore. But what blindingly obvious characteristic do these two things have in common? THE CORRUPT ILLEGITIMATE UNITED STATES SUPREME COURT!!!
Most hopeful story: There is a tiny glimmer of hope that Americans might actually value more walkable communities. And this is also a tiny glimmer of hope for the stability of our global climate, driver/bicyclist/pedestrian injuries and deaths, and the gruesome toll of obesity and diabetes. But it is only a glimmer.
Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both: We are all susceptible to the “end of history effect” in that we tend to assume our personalities will not change in the future, when in fact they almost certainly will. So one way to make decisions is to imagine how a few different possible future yous might look back on them.
social media, retaliation and revenge violence
In case we don’t have enough to blame social media for, we can now blame it for young American men killing each other. It kind of makes sense. If the main cause of murder in this country is simply young men fighting, and guns simply make that fighting much more deadly, then it just makes sense that social media is a channel fueling that cycle of retaliation and revenge among young men left out of the formal economy.
a new superconductor?
Update 8/17/23: Unfortunately, Nature has debunked the idea below that this was a superconductor. The discussion of why a room temperature superconductor would be nice to have is still relevant.
We have a new superconductor…according to the scientists who believe they created it. Or not…compared to other scientists who haven’t been able to fully replicate it yet. Why are superconductors important?
Superconductors that can operate at room temperature and ambient pressure hold promise for quantum computing, a more efficient energy grid, producing energy from fusion and more innovation… Superconducting materials can conduct electricity without losing energy in the form of heat, which happens as electrons move through a material and interact with atoms.
Axios
This seems to me like something computers/robots could work on. Simulate a jagillion materials to see which could be room-temperature superconductors. Then synthesize the most promising ones, test them, determine the most promising of the most promising, tweak them randomly in a gajillion permutations, simulate them again, synthesize them again, test them again, and so on. You could introduce a little bit of random-ness into the process to avoid going down a path-dependent rabbit hole that ends in a dead end (sorry, way too many metaphors there).
WEF Global Risks Report 2023
And now, without further ado, the top ten global risks for the next ten years according to the World Economic Forum:
Well, what is very clear here is that environmental issues are at the forefront here. We can’t just pretend our human activities are a small part of the larger biophysical system any more, and that the biophysical system therefore has an inexhaustible ability to support our human activities.
Here’s another way they look at it. This is pretty but maybe it tries to do too much in one picture.
So climate change mitigation, adaptation (adaption?), natural disasters and natural resources, which were at the top of the “top 10 list”, are relatively small bubbles in terms of “risk influence” here. But then they drive “large-scale involuntary migration”, “cost-of-living crisis” (food is too damn expensive?), “collapse of a systematically important supply chain” (not enough food at any price?), “geoeconomic confrontation” (war?), “state collapse” and “erosion of social cohesion” (riots over prices, food, immigration, military conscription?). It’s pretty easy to see how these things can interact, with our ongoing squandering of the planet’s biophysical stability as a root cause.
Exxon Lied
I’ve talked about Exxon’s accurate climate science going back to the 1970s before. But it’s just worth repeating in the hopes more people will examine the evidence and reach the right conclusion. They knew. They intentionally lied and misled the public and the government. The entire planet is paying the price today and will pay an even larger price tomorrow. Just a reminder that the obvious climate impacts we are just beginning to endure today are the result of emissions decades ago, when Exxon was doing this science and lying to us all. We have not even begun to pay the price for today’s continuing and accelerating emissions.
