That record ? CO2 levels at their highest in millions of years and still growing faster than ever.

Somewhat reminiscent of something that's been going on for a few months now...
Mais je t'en prie :)
I don't disagree, i'm simply trying to present a somewhat less extreme (and therefore i think more appealing) version of your argument
It supposedly comes from originaly counting in base 20 ( a.k.a : vigesimal system) in some proto-european language. There are traces of it in breton, albanese, basque and danish for example. Even in english, there is a reminiscence of vigesimal, in the "score", see for example Lincoln's Gettysburg Address which famously starts with : "Fourscore and seven years ago...", meaning 87 years ago.
You don't even have to rig a bomb, a better analogy to the sensor spoofing would be to just shine a sufficiently bright light in the driver's eyes from the opposite side of the road. Things will go sideways real quick.
There's a typo in the title. If you go back to the original source (in french), they actually retain 79,5 % of their original efficiency, so even better than the article's title would have you believe.
Dr Becky is an actual astrophysicist (PhD) and her content is great and based on a thorough analysis of published science. Maybe watch the video first next time ?
That's how you land on my wishlist !
Besides, helium leaks make radio chatter way more entertaining.
TL,DR : CO2 concentration in air is easily measured and has been used as a proxy to monitor the level of potentially infectious particle people would release in a room while breathing. The idea is the more people breathe, the more they release CO2 and also possibly infectious particles.
It turns out that CO2 also plays an important role in buffering the pH of the aerosolized particles in which viruses like SARS-CoV2 travel from one person to the next. Dissolved CO2 is slightly acidic and prevents the particles from becoming too basic, which would destroy the virions. In doing so, higher CO2 concentrations in ambient air significantly extend the survival of the airborne virus and thus the average time these particles remain infectious.
A CO2 concentration of just 800ppm (parts per million), while usually considered a value consistent with a well ventilated room, is nevertheless enough to significantly extend the lifespan of viruses. This means we should strive to lower CO2 concentrations in rooms as much as we can during epidemics.
