Painavaa puhetta ilmastosta todellisilta asiantuntijoilta
Alla kaksi alan huipputiedemiestä perustelee,miksi antropogeeninen (ihmisen aiheuttama) ilmastonmuutos on pötypuhetta. Prof. Fred Singer on alan todellinen "Grand Old Man", Virginian yliopiston ilmastotieteen emeritusprofessori,joka oli myös Yhdysvaltain sääsatelliiittiohjelman ensimmäinen johtaja 1964-66. Toinen on edelleen virassa oleva MIT:n (Massachuset Institute of Technology - maailman arvostetuin teknillinen yliopisto) ilmastotieteen professori Richard Lindzen.
"He finally quotes Susan Solomon, the former co-chair of the IPCC 2007 Science Team, as claiming that “multiple lines of evidence support AGW” – without listing any.
QS tries to dispose of what he calls “Enduring climate myths [by skeptics]” – which all happen to be facts:
* Climate models cannot provide useful information about the real world
* Global warming stopped ten years ago
* Temperatures were higher in pre-industrial times
* Temperature records taken in the lower atmosphere indicate that the globe is not warming
* A few degrees of warming are not a big deal
* Measured increases in temperature reflect the growth of cities around weather stations rather than global warming
But the real holes in climate science are these facts, never mentioned by QS or by the IPCC:
* The absence of ‘fingerprint’ data that would indicate a substantial warming from CO2
* The absence of data for positive feedbacks that might amplify the effects of greenhouse gases like CO2
* The empirical evidence that shows the control of climate fluctuations on a decadal scale by solar activity by way of cosmic rays"

"The IPCC claim that most of the recent warming (since the 1950s) is due to man assumed that current models adequately accounted for natural internal variability. The failure of these models to anticipate the fact that there has been no statistically significant warming for the past 14 years or so contradicts this assumption. This has been acknowledged by major modeling groups in England and Germany"
