PV! All the rage on X these days, are photos of sensors showing extreme CO2 levels on board of airplanes.
This is very easy to fake, using your own breath. Put sensor into plastic bag, breathe into it, wait for air to cool off, take foto, enjoy outrage. Cheap. Don't fall for it.
Dead giveaway is the high humidity level of 60% in this pic. Normal humidity on board of planes is in the 30's.
