400ppm CO2 Threshhold About to be Crossed

Cape Grim in Tasmania, Australia is about to be the first place in the world where the CO2 content in the Earth's atmosphere is measured at 400ppm.

"The following chart, compiled by CSIRO researchers using atmosphere and ice core readings, show how CO2 levels have risen over the past 2000 years."

"Cape Grim's readings are significant because they capture the most accurate reading of the atmospheric conditions in the southern hemisphere and have records going back 40 years."

The 400ppm figure has been temporarily exceeded in the past but this time there will be no going back.
