Peak carbon dioxide levels surpass 411 parts per million for May

In response to a recent reader comment about wide fluctuations in CO2 readings at Mauna Loa, Ralph Keeling and Stephen Walker of the Scripps CO2 Group gave the following answer: It’s fairly normal, especially in the summer time, to see strong afternoon “dips” in the CO2 concentration.
