Failure Evidence for All 21 Ipcc Positive-Feedback Climate Models

Authors: Nigel B. Cook
Comments: 8 Pages. Version 2.

NASA incorrectly claims that any cosmic radiation increases deliver energy directly and cause temperature rises. Because this does not happen (the opposite occurs, see Fig. 5), NASA claims that cosmic radiation does not have any effect on climate. However, increases in cosmic radiation increase high altitude cloud cover by the “Wilson cloud chamber” effect (well proved in nuclear physics), and so have a cooling effect on the earth’s climate by increasing Earth’s albedo. This mechanism is justified by a correlation between temperature and the inverse of the cosmic ray intensity (Fig. 5). The only reason why significant CO2 related temperature rises are predicted by all 21 IPCC climate models is that they all contain the same error: assuming that water vapour absorbs sunlight to amplify the CO2 injection by positive feedback, ignoring the fact that it would gain buoyancy, rise and condense into cloud cover. It is easy to prove that any net positive feedback by water vapour (which all IPCC positive feedback climate models assume) would have boiled the oceans off long ago and would have prevented human life from evolving. Since H2O vapour is a greenhouse gas 26 times more powerful in the atmosphere than CO2, it follows that the atmosphere did not need to wait for human CO2 emissions before H2O kicked in. Water positive feedback would have kicked in and endlessly accelerated of its own accord millions of years ago, if it were positive. Whenever the rate of increase of a variable is proportional to that variable, you get self-feedback, thus an exponential rise in that variable. Positive feedback on temperature T implies the rate of rise of temperature, dT/dt, is proportional to temperature, T. Hence dT/dt = cT, where c is a constant. Thus: (1/T)dT = c dt. Integrating gives ln T = ct. Making both sides powers of e (base of natural logs) then gets rid of the natural logarithm, yielding T ~ exp(ct). Thus, net positive feedback leads to an exponential temperature rise. This error in all 21 IPCC climate models is not an opinion, or speculation, but a fact of physics, robustly confirmed by evidence. The temperature, if positive feedback were true, would have boiled off the oceans hundreds of millions of years ago in a runaway greenhouse effect like that on Venus. Water does not have positive feedback.

Declining Relative Humidity in the Thompson River Valley near Kamloops, British Columbia: 1990-2012

Authors: Sierra Rayne, Kaya Forest
Comments: 8 Pages.

Potential time trends in relative humidity (RH) were investigated for the Kamloops climate station in south-central British Columbia, Canada, between 1990 and 2012. Mean monthly 6 am and 3 pm RH at Kamloops achieve annual minima during the March to September period with substantially higher early morning RH compared to the mid-afternoon period. Significant temporal declines in RH throughout the year are evident ranging from 1.5 to 5.7\%/decade. No significantly increasing temporal trends in RH were found. The findings indicate that a continuation of declining trends in RH for the study area may increase the quantity of dust and other atmospheric particulate generation from both natural and anthropogenic sources, possibly resulting in additional threats to local and regional air quality, thereby necessitating inclusion in air quality management planning and modeling efforts.

A Previously Underappreciated Impact on Global Warming Caused by the Geometrical and Physical Properties of Desert Sand

Authors: Yongfeng Yang, Baitian Wang, Jinjun Fan, Jian Yin
Comments: 6 Pages. It is published at World Academy of Science, Engineering and Technology 59, 2011, pp 2054-2059

The previous researches focused on the influence of anthropogenic greenhouse gases exerting global warming, but not consider whether desert sand may warm the planet, this could be improved by accounting for sand's physical and geometric properties. Here we show, sand particles (because of their geometry) at the desert surface form an extended surface of up to 1 + π/4 times the planar area of the desert that can contact sunlight, and at shallow depths of the desert form another extended surface of at least 1 + π times the planar area that can contact air. Based on this feature, an enhanced heat exchange system between sunlight, desert sand, and air in the spaces between sand particles could be built up automatically, which can increase capture of solar energy, leading to rapid heating of the sand particles, and then the heating of sand particles will dramatically heat the air between sand particles. The thermodynamics of deserts may thus have contributed to global warming, especially significant to future global warming if the current desertification continues to expand.
