Yes, it's white due to all of the Aluminium Oxide and Barium they are spraying into our atmosphere to reflect sunlight back out into space. They call this Geoengineering/Stratospheric Aerosol Geoengineering and Solar Radiation Management. It's totally criminal what they are doing without the general public's consent and for the total scam of so called 'global warming'!!
The sky is often much whiter today too and this is also due to the same reason….Aerosols from planes.
'Efforts to reflect away the sun's rays might also make the sky whiter, one of many reasons some distrust such geoengineering schemes'
'An overview of geoengineering of climate using stratospheric sulphate aerosols'
'Stratospheric aerosols seem to offer the most effect for the least investment, and could be deployed soon, but present an unknown risk to the environment.'
A great research site here:
