Press Conference:Long-term temperature readings disprove man-made global warming

Introduction

Temperature readings permit us to portray temperatures in the past and to correlate their development with influencing factors in order to check whether scenarios figured out for the future might be realistic - or not. For instance: the IPCC's postulation that anthropogenic CO2 will cause within the forthcoming decades a tremendous global warming cannot be true if already now worldwide cooling is taking place in spite of ongoing emissions.

It is surprising that temperature readings carried out during the 18th and 19th century have not yet been considered although they are available from 1701 onwards as monthly and annual averages in wetterzentrale.de [The German Weather Bureau].

The author evaluated data from 46 stations worldwide and generated temperature curves with their trend-lines. They were used to ascertain the annual change rates of the temperature variations. These changes do not confirm the wide-spread conviction of a global climate change but identify merely rather small temperature variations. They yielded a slight warming in approx. two thirds of several regions but likewise a slight cooling in the others.

The positive experience gained with this first evaluation motivated one to determine the trends of NASA-temperature curves from 776 stations located all over the world. Stations established already in 1880 were preferably analysed. It became evident that warming within the pre-industrial age also occurred faster than nowadays. Invariable trends or even cooling were diagnosed for 74% of all stations, although with differences from continent to continent. These trends superimpose periodical temperature variations of second order and regional differences. Only 18.8% of the stations recorded warming, of which a substantial portion belongs still to the category of urban development since only very few and very clear cases were assigned to the Urban Heat Island Effect. Contrary to computer based scenarios - and hence contrary to what is generally believed -- anthropogenic CO2 is meaningless because its influence is not recognizable.

Of course this result complies with the basic laws of physics and is not really surprising.
