CO2 trend map

This post provides an alternative presentation of Muana Loa CO2 data used to prepare analysis of April, May and June. In fact, the chart shown below was produced in the same Excel file used to generate monthly trend charts presented in earlier posts.

Year-over-year change in CO2 occurring each month, from January 1960 through June 2010, is presented below. That's 606 data points in one chart. The chart used color to parse data points between three levels of change in CO2, with the highest level (monthly increases greater than 2ppm) shown in red. This is a different view of the CO2 trend over the past 50 years, which was previously discussed here.
