(Mauna Loa; green), global sea surface temperature (HadSST3; blue) and global surface air temperature (HadCRUT4; red dotted). All graphs are showing monthly values of DIFF12, the difference between the average of the last 12 month and the average for the previous 12 months for each data series. Last month included in analysis: March 2014. Last diagram update: 1 May 2014.

Following text about 1958 as a starting date for graphs using Mauna Loa CO2 measurements appears two charts below above chart. None of the charts on the page have separate titles:
"The Mauna Loa data series begins in March 1958, and 1958 has therefore been used as a starting date."

Added: Climate4you.com has more charts and graphs for those interested. Too bad GOP "leaders" John Boehner and Mitch McConnell aren't interested.
