Carbon dioxide in the atmosphere is measured in parts per million (ppm). Yearly average carbon figures dating back to 1958 come from Mauna Loa (Hawaii) and the South Pole. Carbon figures before 1958 come from measurements of ice core samples in Antarctica.
Carbon dioxide is at levels our species has never experienced before—this is not new. We have known about this for half a century, and have failed to do anything meaningful about it. What’s it going to take for us to wake up?
