Seeing some comments that the Zhengzhou floods are a result of cutting corners on infrastructure, which seem pretty dubious to me.
Water and flood management is, after real estate and manufacturing, by far the largest sector that China spends money on.

Fixed asset investment in water and environment is more than in transport, education and health PUT TOGETHER.

stats.gov.cn/tjsj/ndsj/2018…
In terms of *state* investment, China is basically a dam-building program with an army.

But flood management is hard and often counterproductive, and the Yangtze and Yellow are two of the most destructive rivers in history in terms of floods.
Zhengzhou sits on the banks of the Yellow River and the rainfall has been without precedent.
These floods worldwide are a warning to us all about climate change — a warmer atmosphere can hold and then drop more moisture than it ever did historically — but the "shoddy infrastructure" thing is getting old.
If there's an area China needs to course-correct on infrastructure and flooding, it's the way that the manic pace of infrastructure buildout is itself causing vast emissions of its own, and increasing climate risks.

SMH that someone who's become the world's richest man *on the basis of a logistics business* thinks our planet needs to import resources and goods from space:

IDK is there a reason Amazon doesn't offer same-day fresh food shipping to any spot on the face of the planet?

Maybe think about that before deciding we need to start importing moon nickel.
Will there be any pollution from moving all the polluting industries to space using rockets that burn a ton of methane every second? Image

Does anyone know of a good history of the German fertilizer industry in World War 1?

The Haber-Bosch process for making synthetic ammonia was invented in Germany on the eve of war, but the plants were all switched to making explosives instead of fertilizer.
Britain then blockaded German ports to prevent imports of fertilizer, causing agricultural productivity to collapse. This resulted in food riots and starvation which may have helped turned the tide of war against Germany.
Did Germany make the right choice in prioritizing ammonium nitrate explosives over ammonium nitrate fertilizers?

Could it have achieved a better outcome by trying to do both instead of focusing so heavily on explosives?

This is ... not a smart way of inducing compliance with lockdown measures from people who are chafing at lockdown measures:
"Flout the public health orders we're making and you'll get the let-it-rip policy you always wanted."
It only makes sense if you think anti-mask types have the same perception of risk from Covid as the rest of us, so will remain compliant for self-preservation reasons.

Pretty obviously, that's not what's been happening.

This is very good on Australia's vaccine communication mess:

theguardian.com/australia-news…
I'm quite struck by this passage, which seems overconfident to me.

Nearly 1,000 people have died of Covid in Australia. We had multiple days of 20+ deaths *in Victoria alone* last winter. Image
Public health experts are trying to communicate age-specific risks in the best way possible so I have huge sympathy.

However, anecdotally so many people I speak to are *terrified* of the AstraZeneca vaccine. Communication isn't working effectively if that's the outcome.

Does the head of Harvard's endowment understand how short-selling works?

Because this idea of using short positions as carbon offsets makes no sense to me.
bloomberg.com/news/articles/…
He's arguing that shorting an emitter's stock puts pressure on the company to change similar to activist investing, and raises its cost of capital.

I bet short-sellers wish it was that easy!
To the extent short-sellers have any effect on a company's cost of capital, it's by *bringing fresh information to the market* about its risk profile.

But you don't need the Harvard endowment to tell you that heavily emitting companies have a Net Zero problem! We all know this.

If you think about the core business of a physical commodity trader — arbitrage of time, place and quality — this makes a lot more sense.
Storage (owning a lot of oil tanks, or taking advantage of price rises while your tankers are steaming across the seas) has long been key to the business.
The storage opportunity in a renewable economy is enormous, whether it's buying cheap midday solar and holding it for the evening grid load peak or doing the same on a seasonal basis for summer or winter cooling and heating loads.
