Arne Sortevik (FrP): Når siste offisielle globale temperaturmålinger fra Met Office (UK) sammenlignes med prognosene fra IPCC over global temperaturøkning fremvises hvor feilaktig IPCCs temperaturprognoser har vært og fortsatt er. Dette er alarmerende informasjon sett på bakgrunn av hvordan Klimapolitikken spesielt i Norge drives av hypotesen om at menneskeskapt CO2 øker temperaturen på jorden. Nettopp faktisk temperaturmåling av god kvalitet gir mulighet til å justere mål, strategi og tiltak i forhold til feilaktige prognoser.
Jeg viser til internasjonalt presseoppslag:
"Myles Allen, Oxford University’s Professor of Geosystem Science, said that until recently he believed the world might be on course for a catastrophic temperature rise of more than five degrees this century. But he now says: ‘The odds have come down,’ – adding that warming is likely to be significantly lower.
Prof Allen says higher estimates are now ‘looking iffy’.The graph confirms there has been no statistically significant increase in the world’s average temperature since January 1997
Its source is impeccable. The line showing world temperatures comes from the Met Office ‘HadCRUT4’ database, which contains readings from more than 30,000 measuring posts. This was added to the 75 and 95 per cent certainty bands to produce the graph by a group that amalgamates the work of 20 climate model centres working for the IPCC.
Piers Forster, Climate Change Professor at Leeds University, said: ‘The fact that global surface temperatures haven’t risen in the last 15 years, combined with good knowledge of the terms changing climate, make the high estimates unlikely.’ Professor Judith Curry, head of climate science at the prestigious Georgia Institute of Technology, said: ‘The models are running too hot. The flat trend in global surface temperatures may continue for another decade or two.’
James Annan, of Frontier Research For Global Change, a prominent ‘warmist’, recently said high estimates for climate sensitivity now look ‘increasingly untenable’, with the true figure likely to be about half of the IPCC prediction in its last report in 2007.Avowed climate sceptics are more unequivocal.
Dr David Whitehouse, author of a new report on the pause published on Friday by Lord Lawson’s Global Warming Policy Foundation, said: ‘This changes everything. It means we have much longer to work things out. Global warming should no longer be the main determinant of anyone’s economic or energy policy.’
