"Extrapolations" TV Show seems like a must watch!

"Cautious to a fault on quick or gradual piloting and deployment (depending on method see below), given the urgency of triggering irreversible tipping points potential to prevent or reduce increased catastrophic harm to humans and the fact that (mentioned by some participants) that the Mt. Pinatubo volcano for example lofted about 17 million tons of SO2 to the stratosphere (far more at one time than any SAI planned deployment that I am aware of) and cooled the globe by roughly 0.6 C for 15 months without any (at least prominently publicised) adverse impacts."
My understanding is that a common reply to this is that volcanoes are "one shot" events, whereas SAI deployment (though probably of a lower magnitude) would be continuous over a long period of time. But here again for example, from modeling, the Montreal Protocol report did not find anything like "catastrophic risks" (see this thread: https://mail.google.com/mail/u/0/#sent/QgrcJHsNnjqBJRQXpRWfqzCKMtqkXxVcQgb ). Certainly not anything like the risks of continuing to pursue the present course of emissions reduction and drawdown only policy that the show (again from the article) attempts to depict.
Best,

Hopefully the episode on geoengineering is more balanced than this:"I also asked him about his decision to devote an entire episode to geoengineering, the controversial idea of spraying chemicals into the atmosphere to try to cool the planet. It’s a strategy that critics say could go horribly wrong, abruptly altering the climate with unpredictable and irreversible consequences. Was Burns at all worried about lending credence to geoengineering as a one-stop climate solution just by giving it so much airtime, even as some of his characters decry the potential dangers?Burns told me he’s personally frightened of geoengineering and felt the need to sound an alarm bell, working with writer Dave Eggers to craft the episode. He also said the high-stakes storyline offered a key source of drama — and if he wants more film and TV producers to follow his lead on climate, he needs to show that these stories can be entertaining, not just educational."David
