Odd Introduction to a New Paper

The Rabett has an interesting post about a paper that appeared recently in Climate of the Past on temperature trends in data measured at the Mauna Loa Observatory (MLO). Most of us are very familiar with the data on CO₂ concentration from Mauna Loa, but I didn’t know there’s also temperature data from the same location since 1977. Interestingly, the data are not just monthly, not just daily, they’re hourly, and because MLO is an atmospheric observatory, the data were recorded not just to the nearest whole degree, but to the nearest 0.1 deg.C.
