There has been a lot of CW discussion on climate change. This is an article written by someone that used to strongly believe in anthropogenic global warming and then looked at all the evidence before arriving at a different conclusion. The articles goes through what they did.
I thought a top-level submission would be more interesting as climate change is such a hot button topic and it would be good to have a top-level spot to discuss it for now. I have informed the author of this submission; they said they will drop by and engage with the comments here!

Notes -
The world is warming and the climate is shifting. Not catastrophically, so far. They just bumped up all the growing season maps for the USA, farmers don't make shit like this up with money on the line. Here in Maine winters are becoming warm and wet, the bays don't freeze up in the winter anymore. Lobsters have all but disappeared from the NE States south of us and NY state and are slowly moving into slightly cooler Canadian waters. We've had more 100 year floods in the last few years than in the last 100. It IS changing, very rapidly on a geological time scale, it doesn't really matter if it is human caused or not; we should stop it.
I'm a big proponent of climate engineering or "geoengineering" . Our whole world is already shaped by humanity and our impact on it, I see no reason why altering the climate on purpose instead of on accident is so much worse. We should start with sulfur now, because it is cheap, we know it works, and how it works and that is is safe. Move on to space based shields later if it is still required. As many of you may have noted if you were in the path of the eclipse, no one would ever notice a 1% drop in sunlight.
Basically, climate change is a solved problem. If it ever gets bad enough we'll do something about it, I hope we do it sooner, I want my winters back.
I always thought one of the paradoxes of climate science was that (1) climate modeling is sound enough to project far into the future and determine magnitude, causality, and predict ecological, social, and economic impacts. And (2) geoengineering would be too dangerous because we don't know what the long term effects will be. That's probably not the exact phrasing of the IPCC or other consensus positions, but I don't think it's unreasonably far off either. Very speculative, but I suspect some of the skepticism of climate activism is that the solution always seems to be more socialism, rather than we would like to spend 0.005% of GDP to spray some calcite into the stratosphere.
I think one of the better arguments against geoengineering is that I don't trust the geoengineers to remain aligned with what works out best, but will likely end up with internal incentives which could possibly lead to a dramatically messed up climate. You could easily imagine people spending too much to cool the earth, if the incentives were such that that were high-status or otherwise rewarded behavior.
That said, it's probably worth attempting anyway, if we're going to be trying to mitigate anthropogenic climate change (assuming the article here is wrong and that's a thing), as it's so much cheaper. Just, it'll require care in how it's set up.
By that logic, how do you trust anyone to do anything? Stuff still needs to get done, even if the incentives aren't perfect. The world turns.
You might have noticed these days we (I) don't trust the media and authorities to tell us the sky is blue today. I seriously don't trust these people not to fuck it up and engineer an even greater climate disaster.
That is your prerogative, things still happen.
