Why we won't stop global warming - Opinion - Al Jazeera English
It may be difficult to imagine the world in which your children's children's children might live but it's pretty obvious that there's a problem when you (and your child) can't go outside because of poor air quality and can't swim in the local lake or river because of elevated bacteria levels.Skeptic's Corner: "Very rarely" ain't never
"Very rarely"ain't never and to use current geological and climatic events which, by their own admission, are neither unprecedented or often times even all that unique as a basis to fund research is nothing less than fraud. The fact that they can not even explain the previous events but simply label current similar events as being caused by man made influences is not only unscientific, it is immoral.Cold weather kills 29 in Mexico

Dr Roy Spencer continues not to acknowledge his fundamental error in assuming conduction (diffusion) in a vertical plane causes isothermal conditions. It does not. It creates isentropic conditions, and thus a thermal gradient in a gravitational field.
The Second Law of Thermodynamics states (from Wikipedia)
An isolated system, if not already in its state of thermodynamic equilibrium, spontaneously evolves towards it. Thermodynamic equilibrium has the greatest entropy amongst the states accessible to the system.
Hence the Second Law of Thermodynamics confirms that, at equilibrium, an isentropic state will develop, simply because that is the state which has the most entropy of all states "accessible to the system."
This is why diffusion creates equal temperatures in a horizontal plane, but also unequal temperatures in a vertical plane. Isentropic conditions apply in each plane in equilibrium, but in the vertical plane potential energy varies, and thus kinetic energy does also so that PE+KE=constant..
Hence an autonomous thermal gradient in a gravitational field is a direct corollary of the Second Law of Thermodynamics, and so the GHE is debunked by standard physics.

Roy Spencer's error will be very widely publicised within 2 or 3 weeks in an article likely to be read by tens of thousands.
