Climate science/renewable energy critic Rainer Hoffmann has researched the literature on mean global surface temperature.

Stunningly, he shows that something is not right with the figures coming from the world’s leading climate experts. The figures tell us the mean global surface temperature has dropped 1C over the last 25 years. At that rate, we’ll be in an ice age by the year 2100!

Page 1 of Hoffmann’s two-page pdf file shows literature that says the mean global temperature in 1990 was 15.5C. Page 2 shows the literature that says it is now only 14.5C.

Here’s a chronology of the global mean surface temperature figures from the leading experts over the last 25 years:

1988: 15.4C
Der Spiegel, based on (untampered) data from NASA (see chart below, enlarged here).

1990: 15.5C
According to James Hansen and 5 other leading scientists; they too claimed the global mean surface temperature was 15.5C. Also Prof. Christian Schonwiese claimed the same in his book ‘Klima im Wandel’, pages 73, 74 and 136. 15.5C is also the figure given by a 1992 German government report, based on satellite data.

2004: 14.5C
14 years later, the temperature mysteriously drops to 14.5C, according to professors Hans Schellnhuber and Stefan Rahmstorf in their book: “Der Klimawandel”, 1st edition, 2006, p 37, based on surface station data from the Hadley Center.

2007: 14.5C
And also according to the Holy Climate Bible, the IPCC WG1 AR4 (page 6 of bmbf.de/pub/IPCC2007.pdf).

2010: 14.5C
Reconfirmed by Professors Schellnhuber and Rahmstorf in their book: Der Klimawandel, 7th edition, 2012, page 37, (see chart below, enlarged here) based on surface station data.

2012: 14.5C
Also given by Prof Mojib Latif, March 20, 2012.
