1 AVERAGE JANUARY TEMPERATURE (°F)
Page: 78 FIGURE 3.27 Average air temperature near sea level in January (°F). Temperatures in Central Antarctica are not visible on this map.

3 EVSC 1300 Global Warming

4 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 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
