The standard view re: contrails causing global warming from Google: "Why are contrails bad for the environment? A study that looked at aviation's contribution to climate change between 2000 and 2018 concluded that contrails create 57% of the sector's warming impact, significantly more than the CO2 emissions from burning fuel. They do so by trapping heat that would otherwise be released into space."
WRONG! Contrail are clouds and thus, like clouds they block sunlight from reaching the Earth. They don't "hold in heat" except for a tiny effect from water vapor and CO2 in the exhaust (not actually part of the contrail)
Contrails are like clouds, made of frozen water droplets from water vapor in the exhaust condensing into water droplets or ice crystals.. The environmentalist CO2 alarmists think the exhaust of planes cause global warming because CO2 and water vapor is emitted, both greenhouse gases, but the clouds of ice and water drops are NOT water vapor and cause cooling far greater than the miniscule warming caused by water vapor and CO2. Ever notice it gets cooler when a cloud cover passes over? Water vapor and CO2 are "greenhouse" gasses, but water vapor is a much greater one than CO2. Clouds and contrails, on the other hand, cause cooling! See: https://odysee.com/@sheepfarmstudios:f/is-there-a-climate-crisis-the-science:8
