Evidence that the next Ice Age is near, measured in ice cores, in space by satellites, and on Earth by magnetic pole drift, etc. This video lecture done by Rolf Witzsche is designed to bring the various fields of evidence together that brings us back to the scientific imperative raised in the early 1970s of how to respond to the Ice Age challenge, for which the cover-up global warming doctrine was invented that became a dead issue from 2009 on.
