Hur svårt är det att fatta att det ena inte utesluter det andra? Om temperaturen ökar kraftigt under 90-talet och minskar marginellt under 00-talet så kommer det naturligtvis vara varmare under det senare trots att uppvärmningen därmed har avstannat under detta årtionde.

Logiken är totalt frånvarande ser jag. Eftersom att temperaturen hade sin pik runt 2000 så är det inget konstigt med det då avkylningen är långsammare än uppvärmningen var före. Det medför att det årtiondet är varmare än det föregående trots att trenden är sjunkande.
Läs rapporten lite noggrannare.

Geneva, 8 December 2009 (WMO) – The year 2009 is likely to rank in the top 10 warmest on record since the beginning of instrumental climate records in 1850, according to data sources compiled by the World Meteorological Organization (WMO). The global combined sea surface and land surface air temperature for 2009 (January–October) is currently estimated at 0.44°C ± 0.11°C (0.79°F ± 0.20°F) above the 1961–1990 annual average of 14.00°C/57.2°F. The current nominal ranking of 2009, which does not account for uncertainties in the annual averages, places it as the fifth-warmest year. The decade of the 2000s (2000–2009) was warmer than the decade spanning the 1990s (1990–1999), which in turn was warmer than the 1980s (1980–1989). More complete data for the remainder of the year 2009 will be analysed at the beginning of 2010 to update the current assessment.

This preliminary information for 2009 is based on climate data from networks of land-based weather and climate stations, ships and buoys, as well as satellites. The data are continuously collected and disseminated by the National Meteorological and Hydrological Services (NMHSs) of the 189 Members of WMO and several collaborating research institutions. The data continuously feed three main depository global climate data and analysis centres, which develop and maintain homogeneous global climate datasets based on peer-reviewed methodologies. The WMO global temperature analysis is thus based on three complementary datasets. One is the combined dataset maintained by both the Hadley Centre of the UK Met Office and the Climatic Research Unit, University of East Anglia, United Kingdom. Another dataset is maintained by the National Oceanic and Atmospheric Administration (NOAA) under the United States Department of Commerce, and the third one is from the Goddard Institute of Space Studies (GISS) operated by the National Aeronautics and Space Administration (NASA). The content of the WMO statement is verified and peer-reviewed by leading experts from other international, regional and national climate institutions and centres before its publication.

Jag skulle drista mig till att gissa att era kloka invändningar angående dataserier och mätstationernas placering redan har tagits i beaktande av de likaledes kloka vetenskapsmännen innan publicering. Men det handlar ju till syvende och sist om förtroende för den öppna vetenskapen. Tydligen är detta förtroende tillräckligt för att amerikanska EPA (Environmental Protection Agency) ska bedöma växthusgaserna som en fara för både hälsa och miljö på grund av effekten av dessa.

Men det känns som det räcker nu. Det här är ingen egentlig diskussion, vi skäller ju bara på varandra. Jag tycker det börjar bli tröttsamt. Vi får väl se om jag står ut med att fortsätta.
