Cool. There haven't been any wars due to nations dumping over a TRILLION tons of GHGs in our atmosphere, which has warmed our planet. Why would we start a war because we put less than 1-10 million tons of SO2 into the stratosphere to cool it to swing temps back to something more manageable?

We create global cooling by launching reflective, biodegradable, high-altitude clouds. main side effect: more vivid sunsets;)

We clearly state the risks on our website makesunsets.com/pages/faq and address them with academic sources. And I just shared a paper that also weighs the risks in this thread. Please stop making things up, and say things like, "SAI poses no significant risk." dosis sola facit venenum

Reposted by Make Sunsets

Did you write this paper because there are papers about how CO2 emissions and GHGs are ungovernable, increasing global temps so it's currently destabilizing world security, which might lead to wars? Therefore, the opposite must be true by trying to cool it down?

Conclusion. My feedback, instead of speculating. How about creating the governance around SAI? We'll keep deploying and do it transparently and welcome collaboration.

If people want to understand the risks, here is a paper from a credible expert in the field of SAI that lays out the risks of doing vs. not doing SAI: climate.uchicago.edu/insights/com... I fed the paper into ChatGPT to check if there was actual data in the paper rather than speculation

100

What integrity? You lost it when you wrote this paper: bsky.app/profile/did:...

These authors give scientists a bad name, they fail to provide scientific, empirical, or policy-based proof that Make Sunsets is a “serious risk.” Instead, they rely on speculation and ideological assumptions without demonstrating harm, unintended consequences, or negative governance effects.

5. Misrepresenting Scaling & Impact Make Sunsets isn’t rolling out full-scale SAI—it’s testing at the gram-to-kilogram level. The paper doesn’t distinguish small pilots from global deployment. Innovation starts small; dismissing it outright ignores the path to responsible scaling. DO BETTER!

000

4. Contradictory Governance Stance The authors argue governments have failed on climate but also demand perfect governance before SAI deployment. If waiting for regulation means inaction, isn’t small-scale testing exactly what’s needed to push governance forward?

100

3. Ideology Over Science The paper isn’t a scientific critique—it’s an anti-market rant. It assumes all for-profit geoengineering is bad without proving Make Sunsets' approach is harmful. Climate solutions need science-driven evaluation, not ideological rejection.

100

2. Small-Scale ≠ Dangerous Make Sunsets deploys 1kg SO2 at a time, yet the paper treats this like a full-scale geoengineering project. No mention that fossil fuels emit millions of tons of SO2 yearly. If small-scale SAI is “dangerous,” where’s the evidence?

100

1. No Evidence of Risk The paper claims Make Sunsets poses a “serious risk” but provides zero data or models to back it up. No evidence of harm, no unintended consequences shown—just ideological speculation. Science, not politics, should guide climate action.

000

This is a pretty bold claim, what evidence do you have that our company "demonstrates a serious risk of advancing solar geoengineering?" How are you measuring this risk? Why don't you mention the harm that Silverlinings caused in Alameda in your paper?

If you want to offset your historical emissions in one shot, it generally comes out to more than 1,000 tons based on your age and income of our typical customer; the one-time purchase drops to a $1/ CO2e ton-year via automatic bulk discount pricing.

100

Generally, what we find is that people who make a one-time purchase see it more as a donation and give whatever they can. For $30/month, it will essentially cool your CO2e footprint, and each month, we deliver 30 grams of SO2 into the stratosphere on your behalf to address your historical emissions

100

The higher one-time price helps anchor the value of our service and encourages long-term commitment. We used to charge $10 per CC for one-time purchases, but customers found the difference too extreme, so we adjusted it.

100

This is not "research" you don't even have the correct pricing. Cooling Credits pricing: $1 per CC when you subscribe to a monthly plan (self-serve, cancel at any time). $5 per CC for a one-time purchase of 1,000 units or less. $1 per CC for a one-time purchase of 1,001 units or more

>but we do not have the knowledge to recommend it and the public is nowhere near endorsing it... We can gain knowledge by deploying and measuring. Again, we already tolerate 69M tons of SO2 in the air we breathe ourworldindata.org/grapher/so-e.... We need to shift less than 10% of that higher.

ourworldindata.org

Global sulphur dioxide (SO₂) emissions by world region

Measured in tonnes per year.

To drive the point home, we've already been cooling Earth using SO2, but badly and in the wrong place. If we literally stopped all SO2 emissions, we would live in a 1.9C world. We're proposing to put it higher where it doesn't have the negative effects of ground level SO2 emissions.

Telling the truth so we can learn from mistakes

well, based on your profile pic, your leaders agree to geoengineer on purpose: rebellion.global/blog/2023/10... But we can do better by sending SO2 into the stratosphere instead of what your leaders propose: makesunsets.com/blogs/news/m...

Five years on from the creation of Extinction Rebellion, three co-founders reflect on lessons learnt and how to respond to today's rapidly warming world.

If you find a better org that is actively deploying, support them. We share monthly how much $ we have in the bank, sales, burn, what we failed it/succeeded, and what we're working on next month since inception. Make sure they do the same if you want to back stratospheric aerosol injection.

This is the equivalent of planting 5.16M mature trees that last for a year, assuming each tree absorbs about 21 kilograms of CO2 per year. We are the world leader in cooling when compared to other CO2 removal companies, and we're only two people. Sources: makesunsets.com/pages/who and cdr.fyi

Please stop lying. Mexico has never banned stratospheric aerosol injection. Show proof of the ban from the Mexican government instead of linking your own article. We have also launched over 132 balloons, mostly in California and offset the warming effect of over 108,360 tons of CO2 for a year.

This actually sounds plausible even to my unscientific brain. I will follow you and read more about it. My only question is how will you convince MTG and all those people who think chemtrails are a government plot to kill them that this isn’t just another plot to kill the whole world?😁

Make Sunsets @makesunsets.bsky.social · 28/12/2024

You don't, you just do it. MTG and crew just bitch and moan, they never come up with actual solutions or action. They will take it lying down.

You're thinking of Charm Industrial that puts a negligible amount of bio oil into the ground. We're trying to actually make a difference rather than watch the world burn.

Seriously, share numbers on how many solar panels you've actually installed and how much of CO2 you've offset in 2023 and 2024 because the panels no longer burn fossil fuels and what the fully loaded cost was @cynan.bsky.social. You've got my full attention.

Holy fucking shit, I just looked at your website and I can't even tell what you've done to cool down Earth, I tried to quantify it using ChatGPT. We're just two people and have spent less than $800K to offset the warming of 90,000 tons of CO2. How much as your org spent in the last two years?
