"Many have you seen the Mauna Loa Observatory graphs co2 rising in and bumping up and down in wiggles during the course of the year. I would say that these iconic images are demonstrating not only the impact that we're having on the atmosphere - that is, we have increased by over 40 percent the co2 in the atmosphere - but it also shows a kind-of breathing. If you look carefully those graphs, it's not just a monotonic increase. It's an up and down every season. This is the breathing of the earth. Somehow this gives a sense of a living system, a living planet." - Bob Brecha
