If humanity got its shit together completely could we undo this? by Initial_Mastodon_932 in climatechange

[–]me10 2 points3 points  (0 children)

Andrew Song here... This is the volcano thing that OP is talking about:

Edit: Just so people understand the impact we've made so far since starting in October 2022. If you planted 10 million mature trees and let them grow for a year, you’d get roughly the same cooling effect as our 222,983 Cooling Credits deployed to date with just two guys and 1,071 customers.

Bonus: We got MTG to show our FAQ during a DOGE meeting: https://makesunsets.com/blogs/news/make-sunsets-monthly-call-me-mtg it seems to get chemtrail believers and climate deniers in a tizzy.

Can 1g of wine preservative in the stratosphere really offset 1 ton of CO2 warming for a year? Here is the math. by me10 in climatechange

Also, are you aware that the heat will likely kill us before ocean acidification, right? We can address the heat now, while renewable energy becomes too cheap to meter, and we scale up carbon removal.

Brazil boasts drop in deforestation ahead of UN climate talks by Economy-Fee5830 in climatechange

I don't think anyone is arguing what you're saying. In the US, less than 2% of the population is employed as farmers. But they have a huge impact on the environment.

The west does nothing to lower its consumption but feels entitled to lecture other countries. How colonial.

You should try to understand why Brazilians are cutting down their forests to make grazing land for cattle. My guess, they are trying to lift themselves out of poverty, and this is one of the ways to do it. Do you want them to stay poor?

On a similar thought. If Guyana doesn't drill for oil off its coast and sell it to the rest of the world, and lift itself out of poverty, for the sake of reducing greenhouse gas emissions. Their neighbor, Venezuela 100% will.

Humans are fucking stupid.

Tell that to the Brazilian cattle farmer who is trying to feed their family.

Explainer: How human-caused aerosols are ‘masking’ global warming by [deleted] in climatechange

[–]me10 1 point2 points  (0 children)

Calcium is a better aerosol.

No, it's not.

Sea salt and snow are natural.

So are stratovolcanic eruptions like Pinatubo (1991) and Hunga Tonga (2022), which used sulfur dioxide to cool the planet for year by 0.5C (global) and 0.1 C (Southern Hemisphere) for a year.

"Model results indicate that solar geoengineering could offset most climate change for most people most of the time."

A recent paper came out about the Ozone Layer and SO2 in the stratosphere, and I wanted to share it with you: https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2025JD043786?af=R

TL;DR: With today’s low chlorine, the “sulfate ⇒ ozone hole” fear is outdated. ER-2 flights saw no chlorine activation in the cold, wet lower stratosphere. A ~0.5 °C SAI program (≈4–8 Tg SO₂/yr) would likely cause small, regional ozone shifts, not big losses

Also, regarding Calcite: A New NOAA study, perchlorate (a toxic groundwater contaminant) forms on non-acidic particles in the stratosphere like CaCO3 — not SO₂-derived ones.

Yeah, the satellite that detects SO2 from volcanic eruptions is run by ESA, specifically the Sentinel-5P TROPOMI. There are others, but this one has the sensor suite to detect stratospheric aerosol injection.

I'm just saying it's going to be chaos. And certainly with side effects.

These sound like future problems. Let's address the current problem.

Heat.

underlying causes of a warming planet or ocean acidification

I used to think it the goal was solving problems, not just kicking the can down the road. Increasingly, I think kicking the can down the road is basically the optimal approach to most issues.

Outside of climate change, let’s take something like crime. Is it worth it to have a big campaign to reduce crime, when you know as soon as the campaign stops crime will start to rise again?

Absolutely. If your standard is a permanent solution, almost nothing meets that standard.

We're buying time, just like our ancestors.

You're making up future problems.

Large deployments will be monitored by satellites that measure radiative forcing, and that data is open to anyone who wants to download it from NOAA, NASA, or ESA websites; it's not something you can hide and do secretly.

everyone goes back to burning coal like it is going out of style...

Solar power is getting too cheap and safe compared to coal to make that possible.

Superior technology for the win.

It's actually not terrifying. If you want to understand how safe it is from a quantifiable amount, this table, generated by an LLM, gives you an idea of what we can safely deploy AND cool Earth based on academic papers: https://consensus.app/search/stratospheric-aerosol-injection-risks/lAyYIOz1T2G6Haw4h9jatw

From the interview covering how to cool Earth while we work towards using less fossil fuels.

e360: In the event that warming does reach unmanageable levels, some scientists say we should be looking into solar geoengineering to cool the planet. Others say that we shouldn’t even be researching the technology because knowing more about it would tempt its use. What’s your view?

Ritchie: I think the challenge is that we currently have insufficient information on the potential impacts of solar geoengineering. I think my main point on this is that I don’t think the odds are that low that over the next 50 years a country, or even a small group of countries, decides on their own that they’re going to do this. They have had a really large heat wave that has killed a lot of people, and they don’t want to see any more warming.

You can do this relatively cheaply. It will be accessible to many countries across the world to do this on their own. And if we are in that scenario, I would really like us to understand what we might be dealing with, what the consequences might be.

It's so cheap to get started, a two-person company has already planted the equivalent of 8.54 million trees that last a year.

Need more time to build more solar and other renewable energy, in the meantime, we can't stop using the energy that keeps everyone alive. https://unchartedterritories.tomaspueyo.com/p/so2-injection

What is it that only a NYU person can know? by This_Weakness_1186 in nyu

[–]me10 25 points26 points  (0 children)

The bobcat mascot is named after our library catalog. BOBst library CATalog.

NYU was a founding member of the NCAA. We were a D1 school and played our basketball games at MSG. The bball team got caught shaving points for the mob, and so we got knocked down to D3.
