It states that half of aircraft pollution is from contrails made of aircraft soot. I’d like to see the literature and discovery of aircraft soot. As an engineer who has built aircraft, I find this fascinating. I would like to measure my amount of soot. How does one go about measuring how much soot I have? Obviously if my exhaust ports are black that’s bad but I’m genuinely curious about this as I’ve always assumed “b…

Fly less. Is waiting a week for a package really that big of a deal? Is traveling less really that much to ask? It’s totally ok to be skeptical of the claims. I can’t make a judgement on them as I know even less than you might.

There is a big anti-tourism movement being built up across the world which is also being pushed by mass media. In Barcelona and Venice this has turned physical in a few instances. Flying is going to be made more expensive in the near future, I've no doubt of it. The environmental lobby will call for it.

By the way, I have not flown for over a decade. I can't stand airports...

Two links about "stratospheric aerosol injection" from mainstream sources.

"The Advanced Research and Innovation Agency (ARIA) - a government backed body - is funding nearly £60m that could allow real-world experiments, including in the UK.

"As part of the Exploring Climate Cooling programme, projects in Solar Radiation Modification (SRM) will involve trying to thicken Arctic sea ice and make clouds more reflective." https://www.bbc.co.uk/weather/articles/c5ygydeqq08o

Paper on how "Low-Altitude High-Latitude Stratospheric Aerosol Injection Is Feasible With Existing Aircraft" https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2024EF00...

I'm out of the loop, didn't the government admit this stuff a few years ago? I was at a presentation in Croatia recently about weather modification in Yugoslavia. This is considered public knowledge there. When Yugoslavia fell apart, Croatia was no longer permitted to engage in weather modification. The main method discussed was the use of small rockets. It was used for agricultural purposes.

The problem is the unsubstantiated logical leap from "weather modification is possible" to "contrails behind commercial aircraft are secretly dispersing chemicals in order to control weather". If I was an evil government figure trying to secretly control weather, there are better ways of doing that (e.g. drones, rockets) than orchestrating a conspiracy that requires hundreds of thousands of people to stay quiet for d…

Yeah, that's true. Besides, it would be morally wrong!

I found this extremely interesting and enjoyable.

I would however recommend testing it on a slower internet connection and a lower end device. Because I was spending 90% of my time in the "loading data" phases, and once the intro was done, the thing ran at one frame per second and I was not able to use it. (I have 5G and I bought my phone last year.)

It is easy to suggest to fly less but it is going to be impossible to convince society where core values include agressive "extra" consumption, which in turn is the backbone of the world's current economy. Flying is one of top "extra" consumption types out there. I know many people are trying to convince people of that, but the society is moving in the opposite direction - bigger cars (both us and eu), more travel. M…

The general way to affect public habits (whether it works or not) is to apply a "sin tax" to that activity.

It literally (and repeatably) crashes Chrome on my android phone that has 6 GB of RAM. As in the entire browser closes.

EDIT: Though it's pretty cool on a powerful desktop. Maybe could benefit from performance optimization.

but contrails are not made of soot, where I define soot as dark unburned carbon, contrails actual are made of water. There is also a highly likely chance I am being to literal and the word choice of soot was a bit of poetic license on the part of the author. As a bonus consideration it might be better if they were made of soot, it would be ugly but water vapor is a tremendous greenhouse gas, several times as potent a…

The water is actually ice crystals and the ice crystals form around the soot.

Just tax everything the amount it costs to clean up the pollution it causes, then use that money to clean up the pollution, now everything will have the correct price including externalities
