When Johnson analysed the frequency at which fractures of different size and duration occur, he found that fractures lasting 1 second or less follow a different statistical pattern to longer ones, indicating that these were caused by algorithms.

Radiation transfers heat across different scales at different optical thicknesses for different frequencies; the net radiant flux depends more on temperature variations that occur over distances on the order of a unit of optical thickness, so the net flux can be through smaller - scale temperature variations.

Abstract — 2008 Climate and wildfires in the North American boreal forest... Climate controls the area burned through changing the dynamics of large - scale teleconnection patterns (Pacific Decadal Oscillation / El Niño Southern Oscillation and Arctic Oscillation, PDO / ENSO and AO) that control the frequency of blocking highs over the continent at different time scales......... Since the end of the Little Ice Age, the climate has been unusually moist and variable: large fire years have occurred in unusual years, fire frequency has decreased and fire — climate relationships have occurred at interannual to decadal time scales...... http://rstb.royalsocietypublishing.org/content/363/1501/2315.short ----------------------

I agree with a lot of your assertions, e.g. the practical irrelevance of the adiabatic and hence essentially reversible ALR — the only mechanism that actually cools the atmosphere (permanently removes heat from it) is radiation, and that occurs in the upper troposphere where the atmosphere ceases to be opaque to e.g. LWIR (although it is more complex than this, this process occurs in depth and at different depths in different frequencies).
