The Milankovitch Mechanism

Variations and the Current State of the Orbital Parameters



Note: The direction Earth is heading on the individual graphs does not indicate
warming or cooling only the change of the parameter.
The change of Solar Forcing is plotted on the final graph.

Solar Forcing by The Milankovitch Mechanism
for +/- 100,000 Years from Present


Updated 19:55z 10.25.2013 to clarify that solar forcing is
represented as mean daily insolation in W/m2, to correct the time and
value of the next peak and to correct the source of data.
