NASA has updated it's measure of the global average concentration of atmospheric CO2 in the month of May. The update is contained in the science agency's monthly climate change monthly newsletter issued in the past day.
it would seem entirely appropriate to cut and paste this information in a thread entitled What's New.
"May's global average concentration of atmospheric carbon dioxide (CO2) was about 414 parts per million (ppm), up roughly 24 ppm from a decade ago," NASA reported.
