@vickyveritas I'm . Why promote something toxic, like cinnabar? geology.com/minerals/cinnabar.. Quicksilver (mercury) was used to process gold and silver during the California gold rush, which must have been harmful to workers parks.sccgov.org/plan-your-vis and created a continuing pollution problem at the mines and in the Sierra mountains where the mercury was used: livescience.com/40794-gold-rus. This process is still used in some places like the upper Amazon with harmful ecological consequences.

#quartz inclusions in garnets in metamorphic rocks record structural information that has been obliterated in the rest of the rock. The processes that create snowball #garnet are illuminated by the quartz inclusions! #MinCup23

This Daily Beast piece on DeSantis' security team tripping over themselves to keep a 15-year-old kid from asking difficult questions is pure gold. Getting big time Dead Zone vibes after reading this story, and this kid is my new hero.

His question should be the first that anyone asks every GOP candidate on the campaign trail for the next 14 months:

“Do you believe that Trump violated the peaceful transfer of power,” the teenager asked the governor, “a key principle of American democracy that we must uphold?”

You know those sliced agate geodes you sometimes see in stores and on display?

Did you know you can "read" them?

Look carefully at the levels, banding, crystal habit and orientation, and you can work out how it formed.

Here's a great guide on how to do that: quartzpage.de/agate.html

It's on the Quartz Page website. Everything fascinating to know about quartz. That's why I'm voting for #Quartz in #MinCup23.

A new exhibit at the Houston Holocaust Museum is taking a look at the travel guides that Black road-trippers used to help them navigate safe spaces in the Jim Crow South.

Similarly, there was no talk of a “free speech crisis” as long as those in power got to define the boundaries of what was / wasn’t acceptable speech – before traditionally marginalized groups gained enough influence and the technological means to make their claims heard. 22/

Nostalgia is a common reaction to change. And weaponized nostalgia is a powerful tool of reactionary politics. Let’s not fall for it. Absolutely no need to mythologize past eras of stable white Christian patriarchal rule.

@CiaraNi Cumulus clouds form from a process that starts with the sun heating the earth, warming the air, which then rises to a point at which the dew point is reached and water vapor condenses into clouds. So it is a combination of heat and sufficient moisture. I have no idea how to fit your observations into an overall global warming pattern. Are you in between areas that are getting heavier rains and those suffering from increasing drought? I don't think you need to be nervous specifically about the clouds unless they turn into big angry thunderheads. But of course we all should be concerned about climate change, regardless of our local cloud patterns.

“Currently about 2/3rds of all Dutch children walk or bike to school, with 75% of secondary school kids cycling to school. By enabling safe and active travel, Dutch cities prevent an estimated one million car journeys to school each morning.” — Chris and Melissa Bruntlett in #CurbingTraffic @modacitylife

Shortly ago Prof. John Perona got in touch to make us aware of his weekly newsletter "Earthward" and his website "From Knowledge to Power," new resources with some mission similarities to Skeptical Science but with strong identity of their own, and powerful content with a "public policy meets science" policy-centric approach.

Excited to learn about John’s website, we interviewed him to learn more of his history and how his site came to be.

Every month I round up the links, books, and media I found interesting. Here's my list for this month. Let me know what I missed! werd.io/2023/the-notable-list-

Thanks to the Supreme Court's 5-4 ruling this May, the EPA was forced to remove protections from most of America's wetlands this week.

Harlan Crow's firm lobbied for the rollback while he secretly plied Justice Thomas with gifts.

Anyone see a problem here?

As our kids go #BackToSchool, never forget that we ARE the traffic that we’re using as an excuse. If more walked, biked or rode transit to school, it would erase a massive number of car trips each day, and our kids would be safer, healthier and better at school.

Spread the word.

@LucyKemnitzer I'm in one of the hot parts of the US now (Colorado) but I do remember that hotter it gets inland, the more the fog sucks in summer days in Santa Cruz

Colonial and present day water exploitation on Maui. "In the late 18th century, when the Hawaiian Kingdom became a sovereign state, Lahaina carried such an abundance of water that early explorers reportedly anointed it “Venice of the Pacific”. A glut of natural wetlands nourished breadfruit trees, extensive taro terraces and fishponds that sustained wildlife and generations of Native Hawaiian families." theguardian.com/environment/20
