Measurements of carbon dioxide, the chief human-caused greenhouse gas, averaged 417.1 parts per million at Mauna Loa, Hawaii, for the month of May, when carbon levels in the air peak, the National Oceanic and Atmospheric Administration said. That's 2.4 parts per million higher than a year ago.

Even though emissions of carbon dioxide from the burning of fossil fuels dropped by as much as 17% in April, it was a brief decline. Carbon dioxide can stay in the air for centuries, so the short-term reductions of new carbon pollution for a few months didn't have much of a big picture effect, said NOAA senior scientist Pieter Tans.
