Global warming: The UAH Lower Temperature Bound, by David Archibald.
This post was on the subject of how consistent the lower bound of the UAH satellite temperature series is. UAH is the satellite record of global warming from NASA satellites, as processed at the University of Alabama in Huntsville.
The lower bound is defined by a total of six monthly data points plotting on the green line in this graph of nearly 40 years of data:
… We will know that global warming is over once that bounding line is broken.
