Hand held co2 tester

[Captain Caveman]

Has anyone bought a co2 tester and gone out to see if the atmosphere is 440ppm?

Or do we take this reading as gospel?

CO2 was about 280ppm at the start of the industrial age that supposedly has caused a climate crisis ending in a DOOMED planet.

Before that, everything was ACES.

All it took was an extra 160ppm of a very weak GHG to destroy the planet!
