@ZLabe on the bright side, it is easier to remove CO2 when it is present at higher concentration??
@ZLabe my new CO2 meter had a calibration routine that involved leaving it outside away from people for about 20 minutes. I wonder how much longer that’ll work.
@ZLabe I am in my 20s and was born at 363 ppm. In that time, half of all carbon emissions have occurred. Doesn’t look like we’re stopping anytime soon.
