Nairobi Airport turns out to be an aberrant CRUT4 station – possible source for the exaggerated warming claim in David Attenborough BBC TV show “Africa”February 19th, 2013 by Warwick Hughes
Following my articles of a few days ago – BBC exaggerated warming trend in David Attenborough’s TV show “Africa” and – CRUT4 surface temperature grid box anomalies trend over Kenya compared to NASA satellites lower troposphere – the source of the David Attenborough 3.5° warming claim explained. I have dug into station data for the 5 degree grid box over Kenya and it looks clear after comparing anomalies with Garissa, that the Nairobi Airport data carries non-climatic warming from the late 1990′s. Although Garissa is almost 300km away in the NE of the grid box and both stations have many data gaps – the difference points to Nairobi Airport data being faulty.

It is a puzzle how Jones et al data can carry such obvious standout mistakes after years of polishing through how many versions? – plus years of input from the UKMO? IPCC science must surely be in a very shoddy state.
