Title seems misleading. It seems that they have results that elevated levels of CO2 in the air increase survivability of viral aerosol particles and infectiousness. Since CO2 is so low (400-1000ppm) this is surprising. Haven't had time to look through the paper closely but seems to be pH related which makes sense.

- dang 2y agoWe've replaced the page title with the HTML doc title now. is that better?
- bilsbie 2y agoFound the critical thinker.
- glitchc 2y agoIf the concentration is so low, would the pH change appreciably? Air is not a liquid after all.
- gpm 2y agoAir isn't a liquid, but the virus is contained within a tiny bubble of water as I understand it. Atmospheric CO2 change acidifying the oceans is a well known effect [1]. Once it's pointed out it isn't surprising that a tiny bubble of water surrounded by atmosphere would change PH quickly in response to atmospheric CO2 levels (the surface area to volume ratio is huge compared to the ocean after all). Nor that that affects viruses. [1] https://www.noaa.gov/education/resource-collections/ocean-coasts/ocean-acidification https://www.noaa.gov/education/resource-collections/ocean-co...
- glitchc 2y agoAh that makes sense. Thanks for the explanation.
- s0rce 2y agoThe CO2 changes the pH of the water by dissolving and forming bicarbonate/carbonate ions.
