CLIMATE CYCLES
AND GLOBAL WARMING

REVISED APRIL 2010
A brief guide to climate cycles and global warming. Natural climate and weather cycles occur at all time scales, and have persisted since the earliest history of the Earth.  Some of the extremes have been devastating for life. The present episode of global warming is not consistent with natural changes in the past, and is almost certainly due to Man's production of "greenhouse gases."
