The UAH satellite program for measuring global temperatures reports the July anomaly was +0.17°C which is a drop of 0.12°C from last month’s report. Dr Spencer points out that this reading is from two new satellites. He says that the old version would have read a smaller positive temperature anomaly but he believes that is due to an uncorrected diurnal drift in satellite NOAA-18. That satellite’s reading are not in the current version.
