The trouble with anomalies… Part 1
The use of anomalies is the normal defense against any critical assessment of the variability of numbers of stations across the climate record – the so-called ‘station drop-out’. The rationale is that it should not matter if stations are located … Continue reading

An indication of the growth of station bias?
[I was tempted to call this “Post Normal Distributions” for reasons that will become apparent, however it wasn’t entirely appropriate. ] Guest post by Charles Duncan Anthony Watts’ excellent http://www.surfacestations.org website raises questions over the extent to which station changes … Continue reading
Climate Parallax
Why different views of the surface temperature record should always be regarded as a good thing. Parallax – noun: the apparent change in the position of an object due to a change in the position of the observer. (Famously used … Continue reading
