From a 2012 Scientific American article, "#Geoengineering Could Turn Skies White":

"Some people might not notice. Others might not care. But even folks who can't tell a picture-postcard blue sky from its milky, geoengineered cousin might be able to detect other side effects of using sulfate to cool the planet."

12 years later spoiler alert: The Experts™ have decided for you; billions of tons of highly toxic chemicals are now being pumped into the atmosphere 24/7/365 to "block out the sun and save us from global warming."

This is why you hardly ever see blue skies anymore.
