  1. Weird how ignoring and denying climate change hasn’t stopped this. It’s almost like ignoring scientists isn’t the best move after all.

  2. Next move is into the Intensive Care Unit on 24 hour medication and strict observation. If only we had told the fossil fuel industry executives and politicians responsible for this earlier, they could have done something to avoid this.

  3. Crossed 7 of 9 boundaries… and that is *not* the “fun” Seven of Nine 🖖🏼

  4. Somewhat fresh in my podcast feed: [https://mcj.vc/inevitable-podcast/captura](https://mcj.vc/inevitable-podcast/captura) An MCJ Collective “Inevitable” episode: “Turning Seawater into a Carbon Removal Solution with Captura”.

    I’m generally not a fan of carbon capture, but some interesting points: 1) CO₂ is ~150x more concentrated in seawater vs. air. 2) Their extraction process *does* seem suited to using variable renewables, at least in part. 3) He did mention the possibility of lowering local acidity of bays.

    If there was any mention of the cost of this process vs. DAC or similar, I missed it. This is always a big red flag. We know the simple deployment of renewables is cheap and effective at displacing combustion and likely the biggest bang for the buck in avoiding further damage.
