In addition to The Key of Sparrows, I was also planning to get these printed for savetheoxygen.org before trying to do something about the 2024 election took priority. So now I have finally gotten these printed too. The text block is printed and glue sticked on, so that is flexible, but I think this is a pretty potent and concentrated message. This has been my most viewed post ever, including stuff I was promoting, while this one was not promoted. Thanks readers! (Technically the original post, not this one which has a shortened and simplified link)

IN ADDITION TO DEAD ZONES CAUSED BY FERTILIZER RUNOFF, CLIMATE CHANGE THREATENS GLOBAL OCEAN OXYGEN
Oxygen only gets into the ocean by surface mixing and photosynthesis in the top 200 or less meters where light penetrates. The deep oceans must be replenished by the lobal thermohaline circulation, the AMOC [ Atlantic Meridional Overturning Circulation ] portion of which is weakening. No one knows when it might collapse. Seawater only contains 6-10 mg/kg of O2 (or less), compared to 210,000 mg/kg of O2 in the air. In addition, warmer waters can generally hold less dissolved gases, of which O2 is one. An estimated 91% of global heating from greenhouse gas emissions is absorbed by the oceans.
99.8% of the ocean is 5.6km or less deep. If the Earth were the size of a basketball, that would be about the thickness of a sheet of copy paper. 95% of the atmosphere’s mass is in the lower 6-18km [ The troposphere is deeper at the equator than at the poles ]. The ISS [ International Space Station ] would be [ at ] less than 8mm elevation.

Also just very good resources (it appears, so far in 2025) for data and learning on these topics.
If you’d be interested in helping me to spread the word, I have a limited number of postcards I can sell direct, and I will update this post later with a link where you can order print-on-demand postcards from Zazzle. For direct sales, contact me at cooper.dozier@gmail.com. As well, if you want to contribute to my awareness raising and activism building effort, you can here or https://buymeacoffee.com/cooperdozier and my other works and projects which you can mostly enjoy for free are listed at https://lintr.ee/cooperdozier.
