I've been seeing the bright flashes of light on the east coast. A few weeks ago it was a clear starry night

The huge double rainbow we have seen twice and one thing you didn't mention, we saw huge lightning strikes on the hills with no thunder. We actually jumped in the truck and tried to get closer it was so very strange. The strikes were thick and wide but no sound at all.

The father of the Gaia hypothesis – the scientifically-informed view of the entire Earth as a single, self-organising, living ecosystem – based a large part of his model on gas exchange between atmosphere, oceans and terrain, highlighting the role of living organsims in mediating and managing this exchange. Try his book, Gaia: A New Look at Life on Earth if you want to learn more about these connexions. It's a pretty easy read for a science book.
The Cosmics Leaving Outdoor Droplets (CLOUD) experiment uses a special cloud chamber to study the possible link between galactic cosmic rays and cloud formation......
Cosmic rays are charged particles that bombard the Earth's atmosphere from outer space. Studies suggest they may influence cloud cover either through the formation of new aerosols (tiny particles suspended in the air that can grow to form seeds for cloud droplets) or by directly affecting clouds themselves.
At the present time we can not say whether cosmic rays affect the climate. What we have investigated so far, is the production of condensation nuclei for cloud droplets, namely those arising from gases: The technical term is “gas-to-particle conversion”. They make up about half of condensation nuclei in the atmosphere. The remaining germs come from soot and dust.
Which gases are involved in this process?
We first looked at sulfuric acid and ammonia. The results of the first tests were: the cosmic rays enhance the formation of condensation nuclei from gases by a factor of ten. But that alone is not enough to significantly affect the formation of clouds. According to our previous experiments, there must be other gases or vapors that enhance this process. Presumably organic substances.
Just after summer sunsets in northern latitudes, shimmering, wispy clouds appear in the twilight sky. This year, these noctilucent clouds have appeared earlier and farther south than ever before.
Noctilucent clouds exist higher in Earth’s atmosphere than any other cloud type. First observed in 1885 following the eruption of Krakatoa, they were a sight reserved for Earth’s northernmost residents. In recent years, however, their intensity and frequency have increased, often at latitudes previously thought to be too far south for noctilucent clouds to form.
