#2Amazing 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 site itself has more information. https://contrails.org/
I guess the map is posted today due to this recent video (worth a watch): https://youtu.be/QoOVqQ5sa08?si=sGK9Q9tUoFOW1QZg

#4I was expecting this to be a gag about chemtrails. I am glad I was wrong.

#5Would 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.

#6I'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"?

Water vapour absorbs the thermal radiation (heat trying to escape earth) better than it absorbs sunlight (heat trying to enter earth). Therefore, the more water vapour in the atmosphere, the stronger the greenhouse effect.

The difference is that water vapour is a greenhouse gas. IIRC the net warming effect of clouds is a function of altitude.

They don’t cause net warming, it’s transient. If we stopped flying tomorrow it would go away quickly. But we keep flying.
But even with that the amount of warming this continuous effect creates is quite small and negligible compared to greenhouse gas warming and isn’t really worth talking about.
