How Accidental Geoengineering May Be Affecting Climate Change. [Re: rise in sea temperature]
@hankgreen: Massively under-reported science story because there's so much going on right now but...it turns out that we might have figured out what's causing this very scary spike. Quick thread, on how WE'VE BEEN A...…
Scientists have discovered that the recent spike in global temperatures may be caused by a reduction in sulfur dioxide pollution from shipping vessels. Ships have long emitted sulfur dioxide, which cools the planet by seeding clouds and reflecting sunlight. However, new regulations that limit sulfur in ship fuels took effect in 2020, leading to a loss of this cooling effect equivalent to a large volcanic eruption each year. Models show this reduction in sulfur dioxide pollution can explain the extra warming seen in the North Atlantic. While pollution is bad, the new regulations provide a natural experiment that gives insight into how intentional geoengineering could potentially combat climate change in the future.
My fear with geoengineering is that is allows us to become complacent about solving the primary problems, and then also creates its own set of unexpected secondary problems.
At least to your second point, in the video he explains that there are ways to seed clouds for cooling purposes without any major side effects, and the experiment hes talking about is that this shows it can be done on a large scale. Whether it would make us complacent on getting CO2 out of the air, though, it might but at least it would be the start of a solution.
become complacent about solving the primary problems
We have been complacent about solving the primary problems for decades. At this point we should be doing all we can, and if a way to combat the symptoms gives us more time to finally get our shit together and do something useful before everyone turns into doomers giving up because it's too late anyway then I think that's a good thing.
You think we can solve primary problems? Cause all I see is us driving off a cliff. If we aren't willing to hit the breaks I'll settle for turning the car into a bush
Have to pave the road as we go. No turning back.

Hank Green has a video about this and maybe we can safely replicate the sulfur dioxide's effects by shooting sea water into the air.
OPs link is Hank’s “blog post” about that video, he links to it in the article.
I wonder if there is a solution that involves a less dangerous gas instead of sea water. Spraying large volumes of water into the stratosphere is not really possible yet, so if it just rose as a gas it would be more doable.
For a second I thought you were calling sea water a dangerous gas.
A while back there was a round of news suggesting calcium carbonate particulate stratospheric injection would be a good substitute for sulfur dioxide.
Step Two: Harvest giant ice cube from a comet and drop it in the ocean every few years
Like the one daddy puts in his drink! …and then he gets mad
Solving the problem once and for all!
Once and for all I said!
Fascinating. Termination Shock by Neal Stephenson deals with the same Sulphur as a way to combat global warming.
Came here to say this. Highly recommended book.
Got my idea to build the torment nexus from the hit sci-fi novel "Don't Build the Torment Nexus".
This is the primary component in producing acid rain, right?
Correct
Hear me out guys, why don't we just put a giant ice cube in the ocean to combat rising temps?
Randall Munroe would like to have a word with you:
Interesting vox video about geoengineering. I find the coalition of scientists demanding we don't even look at geo eng tech, like zero research into it frustrating. https://youtu.be/EKPFZPyQurA
Indeed. There are people who wail and lament about how we've passed a "tipping point" and the climate is doomed to catastrophic warming no matter how much our emissions are reduced at this point, and then when you bring up the possibility of studying geoengineering they snap back at you with a "but not like that" reflex.
Frankly, I think there are environmentalists who like the notion of inescapable doom. It gives them an "I told you so" feeling of victory, perhaps, or absolves them of any further effort. Or they've decided humanity is evil and deserves to be "punished." I don't know, it's just so wearying trying to deal with that reaction.
At the end of the day, when major governments are faced with the choice of collapsing under a wave of migrants and famine and taking a stab at spraying some aerosols into the upper atmosphere as a hail Mary, they're going to try the thing that isn't guaranteed disaster. Would be nice if we could do some studying of it first.
Change is hard, much better to keep doing something that doesn’t work.
Fascinating. I heard something similar with particle pollution in big cities.
Geoengineering is a huge gamble and I want humanity to take it..
Me too, and quickly.
If certain scientists believe they can turn such an inhospitable planet as mars into a liveable environment....why can't we fix up earth?
