Why Climate Change is a cult-

I really enjoy the tweets from the Aerogram since they provide well-curated content. However this third-party article on Monsoon dispersion of pollution is simply rife with generalities and polemicism, high by even BP’s well-worn standards.

The article starts off on a fascinating note:

As South Asia burns fossil fuels, researchers from Germany say the clockwise-spinning storm pulls the emissions high into the troposphere. There, lightning-fueled chemical reactions transform the pollutants into more stable forms, which fall to earth as harmless rain.

A paen to Mother India cleaning up after her messy spawn. However before we could take any consolation in the good news:

By combining these measurements with computer models of air circulation, the researchers tracked the path of the contaminants and how they changed as they reached higher altitudes.

As expected, at lower altitudes, the South Asian monsoon did disperse pollutants over a wide region, including distant areas like Tibet. However, the scientists also found that the monsoon pulled the polluted air from the atmosphere into the much higher troposphere, where with the assistance of the storm’s lightning, it reacted with other gases, and could be washed out by the rain.

Note they use simulated models to track the pollutants so in a way this isn’t verified or empirical based science. It would have been good to actually validate pollution levels in places like Tibet etc. And then for the final piece de resistance:

Unfortunately, Lelieveld told VOA, “the monsoon is weakening, which can reduce the cleaning mechanism. We also believe that the air pollution contributes to a weakening of the monsoon.” He added, “Intuitively, if the monsoon weakens, the pollution will stay more near the ground rather than being transported upward.”

This is a comment that wouldn’t have even passed muster in our own threads. How do we know the Monsoon is weakening and how do know that air pollution is weakening the Monsoon.

I do think it’s fairly straightforward and uncontroversial to state that we should pollute less but it’s increasingly evident that anthropogenic pollution isn’t as clear-cut a topic as we think it is. The Earth does seem to have some feedback mechanisms and it’s also worth reflect if the human scale of pollution can match natural events (like a volcano eruption etc).

We live in a liberal-defined shibboleth and these new orthodoxies are sometimes even more pernicious than the ones of yore since these are draped in the values and ideals of the enlightenment. Please note I’m not necessarily espousing one view over the other but we as learnt in BP; argument from authority (experts) is a logical fallacy and the article above reeks of it.

India Still Rising

The Honorable former U.S. ambassador to India David C. Mulford’s summary of why India is rapidly becoming a great global superpower and why PM Modi might become the best PM in Indian history. My estimate is that India will have more billionaires than America in less than a generation. When this happens what is to stop post modernists from decrying “Asian supremacy”, Asian hegemony, Asian exploitation, Asian empire, Asian imperialism, Asian oppression, Asian racism/bigotry/ sectariansim? How to reduce jealousy of Asia? Or is this dark future inevitable?

Intellectual Dark Web

I would define the “intellectual dark web” as the confluence and convergence of leaders from classical European enlightenment, hard sciences, technology (including neuroscience, bio-engineering, genetics, artificial intelligence), and east philosophy streams. Among the intellectual dark web’s many members are Dr. Richard Haier, Jordan Peterson, Jonathan Haidt, Ben Shapiro, Weinstein brothers, Sam Harris, Glenn Loury, John McWhorter, Yuval Noah Harari, Thomas Friedman, Maajid Nawaz, Neil deGrasse Tyson, Michio Kaku , Dr. VS Ramachandran, Steven Pinker, Armin Navabi, Ali Rizvi, Farhan Qureshi, Peter Beinart, Gad Saad, Nassim Nicholas Taleb, Dave Rubin, Joe Rogan, Russell Brand.  If Steve Jobs were still alive, I would include him among them. They defy easy labels and are high on openness. I hesitate to label others without their permission, but our very own Razib Khan strikes me as a potential leader of the “intellectual dark web”; although I will withdraw this nomination if he wishes. 😉

Some see the intellectual dark web as the primary global resistance to post modernism. I don’t agree. Rather I see them as ideation and intuition leaders thinking different:

Welcome back Mahathir Mohamad, Hero of Asia!

Welcome back Mahathir Mohamad, our favorite 92 year old PM of Malaysia! Malaysia was one of the centers of the great Arya civilization for thousands of years; now enriched by Confucianism, Taoism, Chinese Buddhism, Islam, and expats the world over. One of the most diverse and immigration friendly countries in the world. One of the most pro business, pro capitalist, pro globalization, pro neo-liberal, pro enlightenment values, and pro moderate Islam countries in the world. A country that fought against the full might of the Soviet Union, China and the global communist block and won. A shining city on a hill. A self assured, self confident Asian Tiger without inferiority complex. One of last great bastions resisting the global post modernist wave.

Carbon Steel and Zinc in India

Inspired by a comment by bharata bharatavanshi.

Zinc: 
The production of zinc by conventional smelting methods presents considerable difficulties; instead of a liquid metal forming at the base of the furnace, zinc forms a highly reactive vapour (with a boiling point of 913°C) which exits the top of the furnace and promptly re-oxidises. Clearly, some method of containing and condensing the vapour out of contact with the air was needed
1217CW - Science in India - Plate 6.12
By the early second millennium AD, these descriptions had become more detailed. The retort was to be shaped like a brinjal, or aubergine, the condenser shaped like a datura, or thorn apple flower, and the zinc ore was shaped into small balls, still using the exotic organic ingredients.

Carbon Steel (Wootz)

The Carbon steel from India and Sri lanka are thought to be source for the famed Damascus Steel Swords, used by Saladin to defeat the Crusaders.

It is the pioneering steel alloy matrix developed in Southern India in the 6th century BC and exported globally. It was also known in the ancient world by many different names including Wootz, Ukku, Hindvi Steel, Hinduwani Steel, Teling Steel and Seric Iron.

Wootz steel originated in India. There are several ancient Tamil, Telugu, Greek, Chinese and Roman literary references to high carbon Indian steel since the time of Alexander’s India campaign. The crucible steel production process started in the 6th century BC,[citation needed] at production sites of Kodumanal in Tamil Nadu, Golconda in Telangana, Karnataka and Sri Lanka and exported globally; the Tamils of the Chera Dynasty (Kerala) producing what was termed the finest steel in the world, i.e. Seric Iron to the Romans, Egyptians, Chinese and Arabs by 500 BC. The steel was exported as cakes of steely iron that came to be known as “Wootz”. Wootz steel in India had high amount of carbon in it.

The Chinese and locals in Sri Lanka adopted the production methods of creating wootz steel from the Chera Tamils by the 5th century BC. In Sri Lanka, this early steel-making method employed a unique wind furnace, driven by the monsoon winds. Production sites from antiquity have emerged, in places such as Anuradhapura, Tissamaharama and Samanalawewa,

Brown fat, the bad kind

Unless you have been hiding under a rock you know that people of South Asian are at more risk for metabolic disease than is the norm. More concretely we tend toward “skinny fat.”

My current BMI 24. By normal calculators I’m normal weight (barely), because the cut-off is 25. But for South Asian we should be worried if we’re above 23.

There is the caveat that muscle is heavier, so one shouldn’t take BMI literally, as opposed to seriously. You know if you have too much visceral fat, you don’t need to weight yourself. The phenomenon of brown guys with big bellies due to years of self-indulgence is a thing. And excess weight among South Asians who reach a certain affluence level seems a thing the world over.

So here’s a question: for those of you who have managed to keep the weight off and stay trim, how do you do it? Exercise? Diet? Both?

Review: Enlightenment Now. Steven Pinker.

I have not so much read the book as scanned it. For most of the book he builds a case for his basic claim that life, for most people, has improved to an amazing extent in the last 200 years and we can thank science, reason and humanism for all this progress.
I assume he has to provide so much data because he knows this is an unfashionable opinion within the postmodern liberal intellectual elite and this bothers him. By listing all these facts and showing us all these graphs, he thinks he can convince even his most skeptical critics that progress is real, and that it is much more widely distributed than most people imagine. Is there something missing from his account of progress? I think there definitely is. I do not disagree with his claim that progress is real. Hunger, disease, violent death, these are not trivial concerns. The tremendous progress in these areas is real, and it is meaningful. Intellectuals who criticize Pinker by pointing to persistent or new forms of ill health, physical suffering or violence should take a break and actually read the book, they will find that he has the data and it is not bad data. Either argue about his data with better data of your own, or argue on some OTHER grounds. On THESE grounds, he is solid. Continue reading “Review: Enlightenment Now. Steven Pinker.”

Was There a Sugar Conspiracy?

Well, not really. Not a conspiracy of the sort you can take to court. A balanced and well researched look back at the nutrition wars and recent talk of a “sugar conspiracy” in this article in Science.

“Was there ever really a “sugar conspiracy”?

Their conclusion:

Historical investigations of “merchants of doubt” have been invaluable in showing that scientific uncertainty is sometimes the product of deliberate acts of deception. Such studies underscore the essential insight that the existing evidence base is powerfully shaped by social forces and political choices, and that had decisions unfolded differently, our areas of knowledge (such as genomics) and blind spots (such as obesity prevention or gun violence) would be shifted. But ahistorical accounts thwart our ability to critically evaluate the often long and zigzag process of scientific conjecture and refutation. They provide spurious cover for changes to policy by suggesting that old ideas are illegitimate. And, they advance a false impression that doing the “right” kind of science will somehow avert the messy business of making policy based on incomplete evidence, public values, and democratic politics

The core of the problem is the willingness to jump in and give “expert” advice when the evidence is so limited (for any advice); but then again, demand for advice was so strong, it was bound to be fulfilled, just as demand for finding a “conspiracy” (fat conspiracy, sugar conspiracy, whatever) is so strong. These things probably arise from deep features of human cognition and social interaction.. anyway, I think this is a balanced article, but maybe not harsh enough about the limitations of nutrition advice and the damage done by experts offering advice where the science is not yet settled..
