    Hi all - very grateful to see this posted here. I'm the director of this project and would be happy to answer questions.We are seeking a high level full stack engineer to join the team to work on infrastructure for this and other efforts. Please reach out if interested - info@contrails.org

    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/c5ygydeqq08oPaper on how "Low-Altitude High-Latitude Stratospheric Aerosol Injection Is Feasible With Existing Aircraft" https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2024EF00...

    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 “black smoke bad, white smoke ok”. As for contrails, disturbing the atmosphere is going to cause some freezing (clouds) at that altitude, at that temperature. How do you suggest we mitigate that? Fly lower and burn more fuel? Fly less and tell people to take the train or that their package will arrive next week?

    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.)

    Amazing visualisation, an excellent tool.Are there other sites that can suggest how much of an issue it is, and how much flight plan tweaking could improve this.Remember kids a 1° C rise in temperature can mean 7% more water vapour in the air, and with water vapour being a greenhouse gas itself this can cause heating and holding yet more water.

    The team behind this is world-class. Among other things, they have developed a python library that could be used to model contrails in your own projects.https://py.contrails.org

    I was expecting this to be a gag about chemtrails. I am glad I was wrong.

    This group is funded by Orca Sciences, which is also behind Standard Thermal.https://www.orcasciences.com/

    I'm not following the logic why contrails cause net warming.Why nuclear blasts - that also introduce lots of particles in atmosphere cause a cooling effect - "nuclear winter"?

    Preserving the aesthetics of the sky is reason enough to stop artificial clouds. Why would we accept such a mess?

    All I really learned from this is that European skies have a much higher density of flights than the rest of the world.If the future of aviation is similar flight densities everywhere then people might actually begin to care about this topic.

    Would be great for shiptracks, too— which used to mitigate 1/3 of the warming impact of maritime shipping — until the 2022 clean fuel standards were implemented.
