Pro Node  The atmospheric greenhouse effect essentially describes a fictitious mechanism. url anchor

The atmospheric greenhouse effect, an idea that authors trace back to the traditional works of Fourier 1824, Tyndall 1861, and Arrhenius 1896, and which is still supported in global climatology, essentially describes a fictitious mechanism, in which a planetary atmosphere acts as a heat pump driven by an environment that is radiatively interacting with but radiatively equilibrated to the atmospheric system. According to the second law of thermodynamics such a planetary machine can never exist url anchor

Answer Node  Lindzen and Choi find low climate sensitivity url anchor

Pro Node  The observed behavior of radiation fluxes implies negative feedback processes associated with relatively low climate sensitivity. This is the opposite of the behavior of 11 atmospheric models forced by the same SSTs. url anchor

Climate feedbacks are estimated from fluctuations in the outgoing radiation budget from the latest version of Earth Radiation Budget Experiment (ERBE) nonscanner data. It appears, for the entire tropics, the observed outgoing radiation fluxes increase with the increase in sea surface temperatures (SSTs). The observed behavior of radiation fluxes implies negative feedback processes associated with relatively low climate sensitivity. This is the opposite of the behavior of 11 atmospheric models forced by the same SSTs. url anchor

Answer Node  Naomi Oreskes' study on consensus was flawed url anchor

Tags:  flawed research, Naomi Oreskes

Pro Node  The claim of “consensus” rests almost entirely on an inaccurate and now-outdated single page comment in the journal Science url anchor

The claim of “consensus” rests almost entirely on an inaccurate and now-outdated single page comment in the journal Science entitled The Scientific Consensus on Climate Change (Oreskes 2004). Benny Peiser conducted a search of peer-reviewed literature on the ISI Web of Science database between 1993 and 2003. Dr. Peiser’s research demonstrated that several of the abstracts confounded Oreskes’ assertion of unanimity by explicitly rejecting or casting doubt upon the notion that human activities are the main drivers of the observed warming over the last 50 years. url anchor

Pro Node  The 30 major droughts of the 20th century were likely natural in all respects url anchor

The 30 major droughts of the 20th century were likely natural in all respects; and, hence, they are "indicative of what could also happen in the future," as Narisma et al. state in their concluding paragraph. And happen they will. Consequently, the next time a serious drought takes hold of some part of the world and the likes of Al Gore blame it on the "carbon footprints" of you and your family, ask them why just the opposite of what their hypothesis suggests actually occurred over the course of the 20th century, i.e., why, when the earth warmed - and at a rate and to a degree that they claim was unprecedented over thousands of years - the rate-of-occurrence of severe regional droughts actually declined url anchor

Global warming continues to cause trouble to this tiny, blue planet: A new record was set Wednesday when Chicago had its ninth consecutive day of measurable snowfall and Flint, Michigan, broke a 95-year-old record early Wednesday morning when the temperature plummeted to a frigid 19 below zero.

The global temperature has been rising at a steady trend rate of 0.5°C per century since the end of the little ice age in the 1700s (when the Thames River would freeze over every winter; the last time it froze over was 1804). The IPCC blames human emissions of carbon dioxide for the last warming. But by general consensus human emissions of carbon dioxide have only been large enough to be significant since 1940—yet the warming trend was in place for well over a century before that url anchor

Models do a very poor job of describing the clouds, the dust, the chemistry and the biology of fields, farms and forests. They are full of fudge factors so the models more or less agree with the observed data. But there is no reason to believe the same fudge factors would give the right behaviour in a world with different chemistry, for example in a world with increased CO2. url anchor
