No record in June

Mega ice melt enthusiasts were disappointed with June's Muana Loa CO2 reading. Atmospheric CO2 increased 2.61ppm over June 2009, representing 0.67% growth in the month. The June CO2 reading stood at 392.04ppm, almost 1 point lower than last month. Atmospheric CO2 typically peaks in May and bottoms in September or October, with an unbroken series of annual C02 increases dating back to initiation of Muana Loa data, in 1958. Muana Loa data is reported by NOAA.

The year-over-year increase recorded in June was another data point towards the inevitability of climate change, however, the pick-up in global economic growth hasn't yet translated to new monthly records for CO2 growth, except for April.
