Another new record set:
The amount of planet-warming carbon dioxide in the atmosphere broke a record in May, continuing its relentless climb, scientists said Friday. It is now 50 percent higher than the preindustrial average, before humans began the widespread burning of oil, gas and coal in the late 19th century.
There is more carbon dioxide in the atmosphere now than at any time in at least 4 million years,* National Oceanic and Atmospheric Administration officials said.
Dr. Tans and others at the laboratory calculated the peak concentration this year at 420.99 parts per million, based on data from a NOAA weather station atop the Mauna Loa volcano in Hawaii. Observations began there in the late 1950s by a Scripps Institution of Oceanography scientist, Charles David Keeling, and the long-term record is known as the Keeling Curve.
Scripps’s scientists still make observations at Mauna Loa under a program run by Dr. Keeling’s son, Ralph Keeling. Using that independent data, which is similar to NOAA’s, they calculated the concentration at 420.78.
