Cita:We are now approaching the annual low point in the Mauna Loa CO2 curve, which typically happens around the last week of September but varies slightly from year to year. Recent daily and weekly values have remained above 400 parts per million. From this it’s already clear that the monthly value for September will be above 400 ppm, probably around 401 ppm. September is typically but not always the lowest month of the year.
Cita:Concentrations will probably hover around 401 ppm over the next month as we sit near the annual low point. Brief excursions towards lower values are still possible but it already seems safe to conclude that we won’t be seeing a monthly value below 400 ppm this year – or ever again for the indefinite future.
