Collapse

First, you need to understand the factors that contribute to one person being low functioning and another high functioning.

Human health, development, and function are multifactorial: Genetics, epigenetics, microbiome, diet, environmental/industrial pollution, socioeconomic influences, etc.

I have a two-step proposal.

1. The first step is to limit the impact of low-functioning individuals. https://www.highiqpro.com/wp-content/uploads/2012/03/IQ-Bell-Curve.png. Right now society is set up so that society is run by the wealthy and the low functioning majority. This results in these people voting for, and implementing policies that exacerbate the problems instead of fixing them.
2. The second step is to take action to raise the level of functioning of the human population. This second part probably takes the most learning for the average person. Most people seem to have a very very poor understanding of human health, development, and function. But I tried to condense it into that one article.

My suggestion for tackling the first step is to implement a cognitive (IQ, EQ, etc.) test for city, state, and federal representatives.

Having an IQ test to vote seems problematic. Firstly because of how things like that were used in the past to disenfranchise certain populations. Secondly, the problem right now is that not enough people vote, and that results in the wealthy controlling the government and laws.

I think a better solution is (at minimum) a cognitive test for anyone running for a government position so that can be factored into people's assessment of them. But possibly that won't be enough and it will be necessary to set some minimum requirements for test results.

This way you don't give the option for dumb people to vote for other dumb people. They only get to choose between two intelligent ones.

Some smart people may be corrupt or sociopathic, so this test should be a full psychological evaluation.

I'm curious if it would be possible to get people like Ibram X. Kendi (who gives an interview here on antiracism, anticapitalism and the eugenicist origins of IQ and SAT tests) to agree on both implementation of this solution and an appropriate IQ/psych test for it. I would base my argument to people like him on this type of data [1][2].

My position is also based on polling data from Australia which showed that a political group that is in the vast minority in most countries is the most intelligent, and largest (percentage-wise) supporters of evidence-based policy and holders of evidence-based beliefs. This coincides with the IQ graph I linked earlier. A cognitive test requirement like this should boost the influence of that party and its supporters.

My suggestions for tackling the second step by making people smarter are in this document (which I haven't updated for years). It's doable via a variety of biological and societal interventions.

The problem again is that it's low-functioning people preventing us from implementing these fixes. Possibly if enough intelligent people understand and agree on these fixes and be vocal enough about implementing them we could get it done.

In my opinion, Fecal Microbiota Transplants (FMT) are one of the most promising aspects of this second step. One problem is the people who qualify to be stool donors appear to be extremely rare. You can read more about the current status of FMT in this blog. If you have the ability to influence or fund clinical trials, read this.

As is, with the health of the population rapidly declining, I feel like I'm living in Idiocracy, and surely collapse will be inevitable if nothing is changed.

One climate scientist said a pending heatwave would "affect a bunch of highly populated areas where there hasn't been quite as many stories about extreme heat recently."

Abstract

In palaeontological studies, groups with consistent ecological and morphological traits across a clade’s history (functional groups)1 afford different perspectives on biodiversity dynamics than do species and genera2,3, which are evolutionarily ephemeral. Here we analyse Triton, a global dataset of Cenozoic macroperforate planktonic foraminiferal occurrences4, to contextualize changes in latitudinal equitability gradients1, functional diversity, palaeolatitudinal specialization and community equitability. We identify: global morphological communities becoming less specialized preceding the richness increase after the Cretaceous–Palaeogene extinction; ecological specialization during the Early Eocene Climatic Optimum, suggesting inhibitive equatorial temperatures during the peak of the Cenozoic hothouse; increased specialization due to circulation changes across the Eocene–Oligocene transition, preceding the loss of morphological diversity; changes in morphological specialization and richness about 19 million years ago, coeval with pelagic shark extinctions5; delayed onset of changing functional group richness and specialization between hemispheres during the mid-Miocene plankton diversification. The detailed nature of the Triton dataset permits a unique spatiotemporal view of Cenozoic pelagic macroevolution, in which global biogeographic responses of functional communities and richness are decoupled during Cenozoic climate events. The global response of functional groups to similar abiotic selection pressures may depend on the background climatic state (greenhouse or icehouse) to which a group is adapted.

Abstract

Large constellations of small satellites will significantly increase the number of objects orbiting the Earth. Satellites burn up at the end of service life during reentry, generating aluminum oxides as the main byproduct. These are known catalysts for chlorine activation that depletes ozone in the stratosphere. We present the first atomic-scale molecular dynamics simulation study to resolve the oxidation process of the satellite's aluminum structure during mesospheric reentry, and investigate the ozone depletion potential from aluminum oxides. We find that the demise of a typical 250-kg satellite can generate around 30 kg of aluminum oxide nanoparticles, which may endure for decades in the atmosphere. Aluminum oxide compounds generated by the entire population of satellites reentering the atmosphere in 2022 are estimated at around 17 metric tons. Reentry scenarios involving mega-constellations point to over 360 metric tons of aluminum oxide compounds per year, which can lead to significant ozone depletion.

Abstract

Arctic amplification—the amplified surface warming in the Arctic relative to the globe—is a robust feature of climate change. However, there is a considerable spread in the reported magnitude of Arctic amplification. Whereas earlier observations and model simulations suggested that the Arctic has been warming at a rate two to three times as the globe, a recent study reports an alarming amplification factor of four since 1979. Here we reconcile this discrepancy by revealing that natural variability has substantially modulated the degree of Arctic amplification. On the basis of three observational datasets and 34 models from the Coupled Model Intercomparison Project, we show that the observed temperature evolutions are distinct from the model-simulated forced responses and that the differences are explained by modes of natural variability. Specifically, the Interdecadal Pacific Oscillation decelerated global warming after 2000, whereas an Arctic internal mode amplified Arctic warming after 2005, both contributing positively to the recent increase of Arctic amplification to fourfold. By estimating and removing the effect of natural variability on the observed temperature changes, we reveal that the externally forced Arctic amplification has consistently remained close to three throughout the historical period.

Abstract

Across the last ~50,000 years (the late Quaternary) terrestrial vertebrate faunas have experienced severe losses of large species (megafauna), with most extinctions occurring in the Late Pleistocene and Early to Middle Holocene. Debate on the causes has been ongoing for over 200 years, intensifying from the 1960s onward. Here, we outline criteria that any causal hypothesis needs to account for. Importantly, this extinction event is unique relative to other Cenozoic (the last 66 million years) extinctions in its strong size bias. For example, only 11 out of 57 species of megaherbivores (body mass ≥1,000 kg) survived to the present. In addition to mammalian megafauna, certain other groups also experienced substantial extinctions, mainly large non-mammalian vertebrates and smaller but megafauna-associated taxa. Further, extinction severity and dates varied among continents, but severely affected all biomes, from the Arctic to the tropics. We synthesise the evidence for and against climatic or modern human (Homo sapiens) causation, the only existing tenable hypotheses. Our review shows that there is little support for any major influence of climate, neither in global extinction patterns nor in fine-scale spatiotemporal and mechanistic evidence. Conversely, there is strong and increasing support for human pressures as the key driver of these extinctions, with emerging evidence for an initial onset linked to pre-sapiens hominins prior to the Late Pleistocene. Subsequently, we synthesize the evidence for ecosystem consequences of megafauna extinctions and discuss the implications for conservation and restoration. A broad range of evidence indicates that the megafauna extinctions have elicited profound changes to ecosystem structure and functioning. The late-Quaternary megafauna extinctions thereby represent an early, large-scale human-driven environmental transformation, constituting a progenitor of the Anthropocene, where humans are now a major player in planetary functioning. Finally, we conclude that megafauna restoration via trophic rewilding can be expected to have positive effects on biodiversity across varied Anthropocene settings.

Hello,

Coming here from the migration post, just noticed that in the sidebar.

Good luck with the move, hope everything went well.

Have a good one

Edit: as a side-note, why didn't you lock the community you left? Usually it's the best way to ensure people actually move to the new one

Abstract

The reflectance of the Earth is a fundamental climate parameter that we measured from Big Bear Solar Observatory between 1998 and 2017 by observing the earthshine using modern photometric techniques to precisely determine daily, monthly, seasonal, yearly and decadal changes in terrestrial albedo from earthshine. We find the inter-annual fluctuations in albedo to be global, while the large variations in albedo within individual nights and seasonal wanderings tend to average out over each year. We measure a gradual, but climatologically significant urn:x-wiley:00948276:media:grl62955:grl62955-math-00010.5 urn:x-wiley:00948276:media:grl62955:grl62955-math-0002 decline in the global albedo over the two decades of data. We found no correlation between the changes in the terrestrial albedo and measures of solar activity. The inter-annual pattern of earthshine fluctuations are in good agreement with those measured by CERES (data began in 2001) even though the satellite observations are sensitive to retroflected light while earthshine is sensitive to wide-angle reflectivity. The CERES decline is about twice that of earthshine.

Key Points

We report on two decades of earthshine measurements of the earth's reflectance made from Big Bear Solar Observatory yielding a large-scale terrestrial albedo

We find a decline in albedo between 1998 and 2017, corresponding to a radiative increase of 0.5 W/m2, which is climatologically significant

The CERES data show the same behavior, which is attributed to a reversal of the Pacific Decadal Oscillation reducing the Earth's albedo
