The articles in this special issue range across such influences on cli
mate as solar emissions, orbital precession, atmosphere, oceans, and p
recipitation, and generally approach, each in some context, human impl
ications of these phenomena. The common underlying theme of all of the
papers is the effect the phenomena have on radiation balance as measu
red by global average temperature. This introductory paper undertakes
a formulation of radiation balance theory that makes it serviceable to
students of regional science. The objective is to go beyond inference
of cause and effect by correlation to causal accounts of cause and ef
fect through regional climatic and cultural processes. This is accompl
ished primarily by revisualization of the energy system with regions a
s dependent spatiotemporal entities, and temporally through a protocol
for regional episode definition.
