Another month has been added to the standstill in global temperature, according to accurate satellite measurements compiled by the University of Alabama and NASA scientist Dr. Roy Spencer (see above). The pause is now 90 months long. In fact a small downwards movement is now discernible, since the trend measured over the last 90 months is minus-0.01°C, which equates to minus-0.14°C a century. It must be noted, however, that such small movements, although widely used by climate alarmists in the upwards direction, are within the margin of error.
As I have noted in recent articles, the Spencer data has been kicked off Google AdSense for “unreliable and harmful claims”. The move demonetised Dr. Spencer’s monthly satellite update page by removing all Google-supplied advertising. Google says it will ban all sites that are sceptical of “well established scientific consensus”. Agenda-driven commentators almost invariably ignore satellite data, which has consistently shown less warming than surface measurements.
Satellite temperature measurements of the atmosphere are generally considered more accurate, because they avoid the urban heat distortions common to surface measurements. It is suggested that such measurements have been pushed higher over time as stationary measuring stations are enclosed by growing urban development. For instance, temperature measurements are common at busy airports. Before the planes arrived at Chicago O’Hare, one of the world’s busiest airports, it was rural orchard fields (as indicated by its IATA code, ORD).
