Mauna Loa Carbon Dioxide Record Page: 8 FIGURE 1.6 (a) The solid blue line shows the average yearly measurements of CO2 in parts per million (ppm) at Mauna Loa Observatory, Hawaii, from 1958 to 2013. The jagged dark line illustrates how higher readings occur in winter where plants die and release CO2 to the atmosphere, and how lower readings occur in summer when more abundant vegetation absorbs CO2 from the atmosphere. Pre-industrial background = 280 ppm Current level = 406 ppm
