Cunningham notes that, while climate alarmists are concerned that the atmosphere currently contains 400 parts per million of CO2, thats only a tenth of the level his spacecraft had to reach before causing concern. In his Apollo craft, an alarm would go off when CO2 reached 4,000 parts per million and, in todays space shuttle, the trigger is 5,000. And, in submarines where crewmen may be on three-month missions, CO2 has to reach 8,000 parts per million before the alarm is activated.
