PS: Atmospheric CO₂ data for Mauna Loa can be downloaded from the Scripps CO₂ site as a timeseries dating from 1958 to present:

That's not a record, though it is a record for February.

Atmospheric CO2 measured at Mauna Loa has a yearly cycle that peaks in May. The current record is 421. It could well hit 422 or even 423 this May.
