USA temps show nothing unusual in terms of rank… Slope is now negative, only a few values even in the top 10 lately, which should be a common event in rising temperatures. Only 6 times in the record were temperatures ranked number one. One of those was in 1998, the last previous was in 1934. The frequency of top 10 events is not unusual at all, and the length of any runs of top 10 temperatures is low compared to global temp runs in the top 10 (currently at 18 years).
