Steve McIntyre has a post up looking at Siple Dome ice core data and Gavin Schmidt’s claim that the data shows”exceptionally high values in the late 20th Century “.
Steve includes an R script and a link to the data so I graphed it myself with a few minor tweaks. The peak year in the period from 1840 to 1994 was 1881.
In the last few days I’ve been graphing some of the data so I thought I would look at CRUTEM3 Southern Hemisphere to see if 1881 was exceptionally warm. And there is some confirmation of ~1881 being really, really warm. These are the ones that jumped out at me (graphs are below).
The 2nd warmest August in the Southern Hemisphere was 1884.
The 3rd warmest December was 1881. (First was 1850, 2nd was 1977)
The 3rd warmest September was 1878.
The 5th warmest July was 1877.
The 2nd warmest June was 1873.
I appreciate Gavin prompting Steve to look at the data so I would look at the CRUTEM3 SH data and realize …. what “global” warming?
