Societal collapses

Historians are now using scientific methods of analysis to summarize how and why societies collapse:

By looking back at past polycrises (and there were many) we can try and figure out which societies coped best…. Pouring through the historical record, we have started noticing some very important themes rhyming through history. Even major ecological disasters and unpredictable climates are nothing new.

Inequality and elite infighting

One of the most common patterns that has jumped out is how extreme inequality shows up in nearly every case of major crisis. When big gaps exist between the haves and have-nots, not just in material wealth but also access to positions of power, this breeds frustration, dissent and turmoil.

Something to take a little heart from:

Fascists and fascist governments, despite their positioning are generally bad at war

War is something fascists value intensely because the beating heart of fascist ideology is a desire to prove heroic masculinity in the crucible of violent conflict (arising out of deep insecurity, generally). Or as Eco puts it, “For Ur-Fascism there is no struggle for life, but, rather, life is lived for struggle…life is permanent warfare” and as a result, “everyone is educated to become a hero.”2 Being good at war is fundamentally central to fascism in nearly all of its forms – indeed, I’d argue nothing is so central. Consequently, there is real value in showing that fascism is, in fact, bad at war, which it is.

Concluding:

The more standard pattern is that fascist or near-fascist regimes regularly start wars of choice which they then lose catastrophically. That is about as bad at war as one can be.

And some more good climate news from the Wall Street Journal via FutureCrunch:

In 2020, Chinese leader Xi Jinping pledged that the country’s emissions would begin falling before 2030 and hit net zero before 2060, part of its plan prepared under the Paris accord. He also said China would have 1,200 gigawatts of total solar- and wind-power capacity by the end of this decade. The country is six years ahead of schedule: China reached 1,050 gigawatts of wind and solar capacity at the end of 2023, and the China Electricity Council forecast last month that capacity would top 1,300 gigawatts by the end of this year.

40% of US electricity now emissions-free

((2023)) Wind and solar are likely to be in a dead heat with coal, and all carbon-emissions-free sources combined will account for roughly 40 percent of US electricity production.

Overall electricity production year-to-date is down by just over one percent from 2022, though demand was higher this October compared to last year. This is in keeping with a general trend of flat-to-declining electricity use as greater efficiency is offsetting factors like population growth and expanding electrification.

That’s important because it means that any newly added capacity will displace the use of existing facilities. And, at the moment, that displacement is happening to coal.

Excellent progress! Of course, electricity generation is not the only source of global warming gases, but it’s an important part. Details at https://arstechnica.com/science/2023/12/40-of-us-electricity-is-now-emissions-free/.

And from FutureCrunch (my bolding):

For the first time in a decade, the EPA has tightened regulations on air pollution, lowering the allowable limit for annual PM2.5 levels from 12 micrograms per cubic meter to 9. The reduction is predicted to reap $46 billion in net health benefits by 2032, including prevention of up to 800,000 asthma attacks and 4,500 premature deaths. NPR

Alzheimer’s progress

For years, Alzheimer’s conferences were like the obituary pages in the local newspaper: It’s where clinicians and researchers in the field went to find out the names of the latest promising drugs to die. Between 1998 and 2017 alone, 146 clinical trials of new Alzheimer’s drugs failed…

The big potential benefit (of new drugs), say Alzheimer’s experts, lies in using these drugs, or others soon to come, in conjunction with a second recent development in the field: diagnostic blood tests that can identify the presence of Alzheimer’s-associated proteins…. Scientists believe that in a few years clinicians may be able to use them to make quick, early diagnoses cheaply, even before patients show any outward symptoms. That suggests a new strategy against the disease: GPs could screen otherwise healthy people for early-stage Alzheimer’s and treat them with drugs that slow the progress of the disease before major damage has occurred. The hope is that eventually, Alzheimer’s will no longer be a terminal disease but a chronic one that can be managed with drugs and perhaps be staved off indefinitely.

Full article also covers the history of the disease, why it was so hard to develop effective drugs, and how PET scans (to detect amyloid and tau in living people) were a game-changer. And remember, this is just the start — the future will only bring better treatments. 4,400 words: https://www.newsweek.com/2023/10/20/can-we-prevent-alzheimers-scientists-say-new-tests-treatments-game-changer-1832957.html.

Bonus: an item from FutureCrunch:

Ten people died from unprovoked shark attacks globally in 2023, a slight uptick over the five-year average. This makes sharks less dangerous than lawn mowers, ladders, champagne corks, jet skis, and lightning strikes. 

Guess which one of those things got an entire article in ABC News?
