University of Washington Paper States Plainly that there has been no appreciable attention paid to Cyclical Analysis of Weather

The introduction to a University of Washington paper is right on point. It warns that there has been way too little investigation into the natural cyclical trends within the climate. The arrogance of assuming we have the power in our hands to change the entire environment within a few decades is absurd. The assumption that the weather has changed must be connected to man is the same stupid assumption that all illness is introduced externally so you have to bleed the patient to get it out. If they died, the theory is not wrong, the patient was not bled soon enough. The environmental global warming crowd has not investigated anything to do with the natural cyclical environment in which we live.
The University of Washington report states:
Although the dramatic climate disruptions of the last glacial period have received considerable attention, relatively little has been directed toward climate variability in the Holocene (11,500 cal yr B.P. to the present). Examination of ~50 globally distributed paleoclimate records reveals as many as six periods of significant rapid climate change during the time periods 9000–8000, 6000–5000, 4200–3800, 3500–2500, 1200–1000, and 600–150 cal yr B.P. Most of the climate change events in these globally distributed records are characterized by polar cooling, tropical aridity, and major atmospheric circulation changes, although in the most recent interval (600–150 cal yr B.P.), polar cooling was accompanied by increased moisture in some parts of the tropics. Several intervals coincide with major disruptions of civilization, illustrating the human significance of Holocene climate variability.
