Teachers, whatever you do, don't tell your pupils that climate science is settled about global warming

 The general awareness of climate science may have been severely contaminated by special-interest groups such as the WWF and GreenPeace intent on swelling their coffers and assuming heroic stances simultaneously.  It is not easy for teachers to present a calm and sensible view in these circumstances, not least if their curricula have already been invaded by such interest groups.  Two things, however, seem reasonably clear: 

(1) nothing extraordinary has been observed in weather phenomena over the past 30 years of the CO2 scare, and much of what has been seen contradicts the forecasts of some prominent alarmists such as the streets of New York remaining above sea level, polar bears increasing in numbers, storm levels failing to increase, and of course tropospheric temperatures refusing to shoot up.

(2) learned scholars dispute the core mechanisms posited by some scientist-alarmists as being at the heart of their concerns.  The quote below is evidence of this dispute:

'Recently, Gerlich and Tscheuschner listed a wide variety of attempts to explain the so-called atmospheric greenhouse effect. They disproved these explanations at the hand of fundamental physical principles like the second law of thermodynamics. By showing that 1) there are no common physical laws between the warming phenomenon in glass houses and the fictitious atmospheric greenhouse effects, 2) there are no calculations to determine an average surface temperature of a planet, 3) the frequently mentioned difference of 33 K is a meaningless number calculated wrongly, 4) the formulas of cavity radiation are used inappropriately, 5) the assumption of a radiative balance is unphysical, 6) thermal conductivity and friction must not be set to zero, they concluded that the atmospheric greenhouse conjecture is falsified.

Based on our findings, we argue that 1) the so-called atmospheric greenhouse effect cannot be proved by the statistical description of fortuitous weather events that took place in a climate period, 2) the description by AMS and W·MO has to be discarded because of physical reasons, 3) energy flux budgets for the Earth-atmosphere system do not provide tangible evidence that the atmospheric greenhouse effect does exist.'
