Yeah I just read this, not really sure what the alternatives are now? Looks like the situation is spiraling out of control so...?? Cover Greenland in a reflective blanket? Sounds like it is time to panic...and actually do what needs to be done.

The time to panic was 1980. We’re well past that point by now, and have already committed to at least a whole degree of warming, if not more. > Cover Greenland in a reflective blanket? Ha! I want to see a study on this now. Greenland already has high albedo so it wouldn’t be that effective; it would protect the ice sheet but also be covered by new snow, if any.

The best time to panic was 1980. The next best time is right now.

For anyone interested in a near-future sci-fi look at how sulfur as a form of geoengineering might play out, check out out Termination Shock by Neal Stephenson[0]. The title[1] refers to what happens when you suddenly stop an effort like that... [0] https://en.wikipedia.org/wiki/Termination_Shock_(novel) [1] https://en.wikipedia.org/wiki/Solar_geoengineering#Maintenan...

I'm still kinda surprised that no novel from Neal have become films or TV shows yet.

I can’t remember who (maybe he’s quoted further in the thread than I quickly scrolled) but there’s a scientist who has been talking about this on Twitter for a long time (when I used to use it). Pretty scary these things can happen, but he was warning basically we are further along with global heating than we thought and this pollution was just masking some of the effect in the Northern Hemsiphere of CO2 we’d already…

Was it Leon Simons? https://twitter.com/LeonSimons8

We should definitely not write for The Hitchhikers Guide to the Galaxy.

Don't feed the shill/troll people.

In order to break the planet a lot more is necessary. We created some problems but the planet is far from broken.

It doesn’t sound like their sulphate correction was due to policy changes.

Do you know how this model went with this years predictions?

You know what happens to soil when it rains salt from the clouds, right? Sulphur at least is more natural, as it's also released by volcanoes. https://extension.psu.edu/sulfur-fertility-management-for-gr...

Good thing we’ve never seen a volcanic eruption impact global temperatures. https://en.wikipedia.org/wiki/Mount_Pinatubo

Or consider the year without summer: https://en.m.wikipedia.org/wiki/Year_Without_a_Summer

Towards the end of that article were links to a few studies. Here's the first linked study I found: https://www.nature.com/articles/s41586-022-05122-0

That study says little about fewer ship tracks causing sea warming and nothing about the magnitude of any possible sea warming.

If you'd made it through the abstract you would have read how ship tracks cause cooling.

There’s been talk of a Seveneves movie or mini series for years….

This is defeatist and also not true. We adopt nuclear, invest in carbon capture technologies, and employ geoengineering strategies as needed until fusion comes online. This is a solvable technical problem with significant political hurdles.

Global overpopulation is absolutely a part of the equation, and everyone is deeply uncomfortable talking about it because there are no palatable solutions to that specific problem.

Humans, as a species, exhibit all the damaging properties of a cancerous growth, and our habitat can no longer support us. As George Carlin said: the planet will be fine, it’s the humans that are fucked!
