A Case for Climate Cycles: Orbit, Sun and Moon

摘要: The success of Milankovitch Theory — which states that ice age cycles are real and a result orbital forcing has made climate cycle research thoroughly respectable. This was not the case when E. Bruckner (1862–1927) pioneered on scale decade-to-century, for last 1000 years, publishing century ago. In 20 years or so, Bruckner’s claim exist at this received much support. Work solar-forced suggests such interfere with assessment human-induced global warming. A portion general warming observed over may be owing to solar activity. If shows considerable sensitivity modest changes in forcing. original 35 is here suggested tidal origin (twice lunar perigee period). Likewise, 1470-y Greenland proposed nature (as beat between nodal cycles, effective during summer season).
