Climate Endgame: Exploring catastrophic climate change scenarios
Abstract
Prudent risk management requires consideration of bad-to-worst-case scenarios. Yet, for climate change, such potential futures are poorly understood. Could anthropogenic climate change result in worldwide societal collapse or even eventual human extinction? At present, this is a dangerously underexplored topic. Yet there are ample reasons to suspect that climate change could result in a global catastrophe. Analyzing the mechanisms for these extreme consequences could help galvanize action, improve resilience, and inform policy, including emergency responses. We outline current knowledge about the likelihood of extreme climate change, discuss why understanding bad-to-worst cases is vital, articulate reasons for concern about catastrophic outcomes, define key terms, and put forward a research agenda. The proposed agenda covers four main questions: 1) What is the potential for climate change to drive mass extinction events? 2) What are the mechanisms that could result in human mass mortality and morbidity? 3) What are human societies’ vulnerabilities to climate-triggered risk cascades, such as from conflict, political instability, and systemic financial risk? 4) How can these multiple strands of evidence—together with other global dangers—be usefully synthesized into an “integrated catastrophe assessment”? It is time for the scientific community to grapple with the challenge of better understanding catastrophic climate change.

Why the U.N. chief says we are ‘one miscalculation away from nuclear annihilation’
The world is now enduring greater stress than any time in recent decades, according to U.N. Secretary-General António Guterres. And while humanity has so far avoided “the suicidal mistake of nuclear conflict,” he said, tensions are hitting new highs at a time when many lessons of the past seem forgotten.
“Today, humanity is just one misunderstanding, one miscalculation away from nuclear annihilation,” the world’s top diplomat said at a U.N. conference on the non-proliferation of nuclear weapons in New York City.
It’s not the first time such a dire warning has been issued about the catastrophic risks posed by nuclear weapons. Here’s a brief look at why Guterres and others are raising the alarm now: LINK
A State-of-the-Art Review on the Use of Modafinil as A Performance-enhancing Drug in the Context of Military Operationality
ABSTRACT
A State-of-the-Art Review on the Use of Modafinil as A Performance-enhancing Drug in the Context of Military OperationalityModafinil is an eugeroic drug that has been examined to maintain or recover wakefulness, alertness, and cognitive performance when sleep deprived. In a nonmilitary context, the use of modafinil as a nootropic or smart drug, i.e., to improve cognitive performance without being sleep deprived, increases. Although cognitive performance is receiving more explicit attention in a military context, research into the impact of modafinil as a smart drug in function of operationality is lacking. Therefore, the current review aimed at presenting a current state-of-the-art and research agenda on modafinil as a smart drug. Beside the question whether modafinil has an effect or not on cognitive performance, we examined four research questions based on the knowledge on modafinil in sleep-deprived subjects: (1) Is there a difference between the effect of modafinil as a smart drug when administered in repeated doses versus one single dose?; (2) Is the effect of modafinil as a smart drug dose-dependent?; (3) Are there individual-related and/or task-related impact factors?; and (4) What are the reported mental and/or somatic side effects of modafinil as a smart drug?
We conducted a systematic search of the literature in the databases PubMed, Web of Science, and Scopus, using the search terms “Modafinil” and “Cognitive enhance*” in combination with specific terms related to the research questions. The inclusion criteria were studies on healthy human subjects with quantifiable cognitive outcome based on cognitive tasks.
We found no literature on the impact of a repeated intake of modafinil as a smart drug, although, in users, intake occurs on a regular basis. Moreover, although modafinil was initially said to comprise no risk for abuse, there are now indications that modafinil works on the same neurobiological mechanisms as other addictive stimulants. There is also no thorough research into a potential risk for overconfidence, whereas this risk was identified in sleep-deprived subjects. Furthermore, eventual enhancing effects were beneficial only in persons with an initial lower performance level and/or performing more difficult tasks and modafinil has an adverse effect when used under time pressure and may negatively impact physical performance. Finally, time-on-task may interact with the dose taken.
The use of modafinil as a smart drug should be examined in function of different military profiles considering their individual performance level and the task characteristics in terms of cognitive demands, physical demands, and sleep availability. It is not yet clear to what extent an improvement in one component (e.g., cognitive performance) may negatively affect another component (e.g., physical performance). Moreover, potential risks for abuse and overconfidence in both regular and occasional intake should be thoroughly investigated to depict the trade-off between user benefits and unwanted side effects. We identified that there is a current risk to the field, as this trade-off has been deemed acceptable for sleep-deprived subjects (considering the risk of sleep deprivation to performance) but this reasoning cannot and should not be readily transposed to non-sleep-deprived individuals. We thus conclude against the use of modafinil as a cognitive enhancer in military contexts that do not involve sleep deprivation.

When will the sixth mass extinction happen? A Japanese scientist may have an answer
- Earth’s average surface temperature and loss of biodiversity have a linear relation
- The biggest mass extinction happened 250 million years ago
- A temperature of 9oC is needed for a mass extinction event
A Japanese climate scientist has run the numbers for the next big mass extinction and does not expect us to reach there till the year 2500 AD, ScienceAlert reported.
Russian Hackers Target U.S. HIMARS Maker in ‘New Type of Attack’: Report

Bretannike Rebellion
Bretannike Rebellion by Juilan Langer
I love a good story from a time before history, even if it’s not really from a time before history.
Or is it?
I have recommended the work of Julian Langer a few times, as you probably remember, and this is another of those times.
Julian has crafted a wonderful “tale of the tribe” with his new work, Bretannike Rebellion.
It’s a nice, light, summer read that is short content-wise but long on thoughtfulness.
Julian and I see eye to eye on many philosophical and environmental issues, and my alter ego, Ezra Buckley, also approves of his work.
I don’t want to ruin the revelation of the work for you personally because I hate when reviewers talk too much about someone else’s work they are recommending, so in the interest of brevity, I’ll simply say, read it.
The tale is entertaining while also being thought-provoking, and the accompanying poetry pieces alone are worth the time investment.
Bretannike Rebellion belongs on your virtual or physical shelf.
