WUWT Readers may remember in 2006 Al Gore announcing on national television one morning that:
The earth has a fever…
He of course was pushing his book, An Inconvenient Truth as the cure. Now, almost six years later, other symptoms have been reported, including spots, which might be from Chicken Little Pox.
Dr. Clive Best writes in with his findings on The Earth running hot and cold !

There has been quite a debate over at WUWT regarding temperature measurements and temperature anomalies. The AGW crew argue that only anomalies can be relied on to track global warming. These anomalies calculated at each individual weather station are the deltas between the measured temperatures and the mean temperatures over a fixed period – just for that station. The anomalies from ~4000 stations all over the globe are then combined to give one global anomaly, yielding the familiar graph we know and love which shows ~0.6 deg.C rise since 1850. Looking in more detail however we discover that some parts of the world are not warming at all and some are even cooling.
Thus motivated I went off in search of the “hot stations” and the “cold stations” from the Hadley/CRU provided station data.
Here we define “hot stations” as those yielding an average anomaly increase since 1990 > 0.4 degrees. “Cold stations” are defined simply as those with an average anomaly < 0.1 degrees. since 1990. Had/CRU anomalies are relative to the period 1960-1989 so they all measure warming/cooling relative to that baseline.
The map above shows in red the “hot stations” and in blue the “cold stations”. In both cases the larger the point the stronger the warming/cooling. This is an active flash map so you can zoom in by dragging a rectangle, and view the data by clicking on any station, (zoom out by clicking anywhere else).
It immediately becomes obvious that the bulk of observed warming is concentrated in the Northern Hemisphere : Eastern Europe, Russia, central Asia, India, China, Japan, Middle East, North Africa. These are all areas of rapid population increase, development and industrialisation. There is essentially no warming at all in the Southern Hemisphere. Bolivia, Peru, Paraguay and Argentina all appear to be cooling. Even Australia and Zealand are static or cooling.
