A white haze eliminates our blue skies most days here and there can be no question where the haze originates. I struggle to understand how water vapor from planes can cut out at least 10% of the natural light?

Independent groups have been taking ground & rain samples for years and I believe the first air samples were taken in 2016... all of which point to increased levels of aluminum & barium, amongst other things.

Geoengineering is real. I don't think there is any debate about that any more.
