What Are These?
These are graphs of the monthly change of temperatures, year over year, and the sum of those changes over the years. A very pure form of “anomaly” process. Each month is compared to the next valid data for that month and the difference is noted (so if January is 1 C warmer than the last time January had a valid data item, you would get the JAN line at 1C on the graph). In theory, over time, this would accumulate to the change of temperature to date. In practice, we see evidence in these graphs that there have been changes to the thermometers and the data record that bias the outcomes.
But we saw North America already?
I’d started doing a “paced” analysis and that prior North America posting was a few specific interesting observations. There were then some requests for specific graphs and a desire for a bit of a ‘jump ahead”, so I responded. I did the Pacific Basin, South America, and Asia sets of graphs as mostly “just the graphs”. Now, looking back at that North America posting, it’s a nice intro / analysis, but not a good vehicle for “A Gaggle of Graphs”…
So here I’ll be putting the graphs, in a more consistent “Hair” format. The “hair” is all that monthly detail. You could suppress it by only showing the “annual average” of them that I’ve labeled “dT/yr”, but it does not give quite as much information (even if it does look cleaner and is less confusing at first sight.)
So this
