Carbon dioxide soars to a new record in Earth's atmosphere as climate change continues unabated.
In fact, those levels continued "a steady climb further into territory not seen for millions of years," NOAA said.
“Sadly we’re setting a new record,” said Scripps Oceanography geoscientist Ralph Keeling, who oversees the iconic Keeling Curve record established by his father 65 years ago.
The carbon dioxide (CO2) level measured in May in Hawaii averaged 424 parts per million, NOAA said. That’s 3 parts per million more than last year’s May average and 51% higher than pre-industrial levels of 280 ppm. It also represents the fourth-largest annual increase on record.
