The Second Law does not say it is impossible for heat to be transferred from a cold body to a hot body. The second law does not say that "disorder" must increase on the earth or anywhere else. Life is not a counter-example to the second law; life is an example of the second law in action.
One has to be very careful about applying statistical results to a single molecule or a few molecules and remembering that increasing entropy applies to irreversible changes, not reversible ones. The second law says nothing about disorder. The second law does not prevent evaporative coolers from operating.
The second law does not contradict radiative transfer theory or global warming. The second law does not contradict conservation of energy. In applying the second law to cosmology, one should tread cautiously.
Subsequent posts in this series elucidate what the second actually does say and how it is misinterpreted. The next post in this series is entitled What the Second Law Does Say.
