Every fortnight I curate among the observations and insights that have been shared on social media. I name these Friday’s Finds. [some links are to the complete Twitter thread]

“If you by no means change your thoughts, why have one?” —Edward de Bono — by way of @stiggylou

“I’m taking an online data analytics class from the Wharton School of Business. The last module is 4.5 hours of how we can track people. Exactly 0 minutes of that is spent on ethics. Just in case you’re wondering what elite business schools are teaching people.”@kyleejohnson

“If you want to get better at something, you have to stress the system to increase its capacity. You don’t get fit unless you exercise. You don’t become more aware unless you train in meditation or similar. You don’t become better at sensemaking with only soundbites and tweets.”@euvieivanova

Why accomplish that many individuals assume that primary-care and ER medical doctors have experience in epidemiology, public well being, and transportation coverage? This is like assuming an HVAC man is an professional in local weather change.@PFlax1

The Limits of Clean Energy — by way of @Notium

In 2017, the World Bank launched a little-noticed report that supplied the first comprehensive look at this query. It fashions the rise in materials extraction that will be required to construct sufficient photo voltaic and wind utilities to provide an annual output of about 7 terawatts of electrical energy by 2050. That’s sufficient to power roughly half of the worldwide economic system. By doubling the World Bank figures, we will estimate what it should take to get all the way in which to zero emissions—and the outcomes are staggering: 34 million metric tons of copper, 40 million tons of lead, 50 million tons of zinc, 162 million tons of aluminum, and at least 4.eight billion tons of iron …

The drawback right here isn’t that we’re going to expire of key minerals—though that will certainly change into a priority. The actual problem is that it will exacerbate an already present disaster of overextraction. Mining has change into one of many largest single drivers of deforestation, ecosystem collapse, and biodiversity loss around the globe. Ecologists estimate that even at current charges of worldwide materials use, we’re overshooting sustainable levels by 82 p.c.

– wind (put in: 50,018MW, produced: 79.8TWh)
– nuclear(put in: 10,728MW, produced: 80.1TWh)
nuclear power does extra with much less”@HenryK_B_
