The unprecedented surge in #atmospheric #methane during the early 2020s was primarily driven by a temporary decline in #hydroxyl (OH) radicals, which reduced the atmosphere's ability to break down the gas, coupled with increased natural emissions from wetlands due to wetter #climate conditions.

depends how hydrophilic it is. Some things, like sulfur trioxide, go after water vapor like a doberman on a pork chop (duh, those things are called "desiccants")

In that both HF and H2O hydrogen bond like crazy, I bet you'd need a low RH to stop this.

Now I'm wondering about water oligomers at say 70% RH. Water is a very sticky molecule, when you pull vacuum on a system pumping out the water is the first challenge.

Interesting discussion

I think I need to tag this

Ozone–oxygen cycle (Biogeochemical cycle 🔄)

The ozone–oxygen cycle is the process by which ozone is continually regenerated in Earth's stratosphere, converting ultraviolet radiation into heat. In 1930 Sydney Chapman resolved the chemistry involved. The process is commonly called the Chapman cycle by atmospheric scientists. Most of the ozone production occurs...

The solar system may have passed through dense interstellar clouds 2 million years ago, altering Earth’s climate

Astrophysicists calculate the likelihood that Earth was exposed to cold, harsh interstellar clouds, a phenomenon not previously considered in geologic climate models.
