As a child like all other children I loved dinosaurs, painted rainbows and admired very rare beautiful sunsets.
Mostly boring sunsets. Sol dropping down without much color in the surrounding atmosphere. My generation rarely saw them and when I first came across Turners work I assumed he was simply part of impressionism fascinated by adding color. Art books rarely talked about anything beyond technique and analysis.
Turner painted sunrises/sunsets obsessively. (1750s)
Turners obsession came during the first industrial revolution. A time when Fossil fuels and particularly steam technology changed the colors of the sky. Back then pollution wasn't much of a concern.
For the last decade I'm seeing individuals all over the world take pictures of rainbows all over the world and something I enjoyed for its beauty and rarity I no longer do.
All these incredible sunsets and rainbows mean increased particulates in the air. Increased through moisture and a lack of settling onto the ground during the day.
Sahara dust windstorm pollution active volcanoes wildfires contribute to this phenomenon especially around evaporating lakes and rivers. Basically soot dust chemicals sea salt ash etc.
Another factor is Co2. Creating heat domes. Humans thrive at 200 to 380 ppm. We're at 420 ppm at the moment. It's one of the reasons our population grew. Dinosaurs thrived at 700 co2 to 2500 co2 ppm. That level would have been toxic to us long term and lasted for 150 million years. Most likely due to supervolcanoes brought about by tectonic plates shifting.
I was watching a relatively recent interview with Arnold Schwarzenegger. When he was governor he couldnt convince anyone; no one cared about smog or pollution, but when he exaggerated that babies were dying he was able to get enough public support to get his bill passed.
I've mentioned before, while obviously important to me and my readers most people don't care about biodiversity, mass extinction but affect health noticeably and we probably would have had better success in preventing this.
P.S. forgot this good article on rainbows
