I just put up on Medium the following-
Historically Significant Political Events Prior to the Ross Perot Period of Presidents
It tells about three major historically important events prior to the time period when the Rosella Tolfree stories are taking place (Ross Perot Period of Presidents).
One would think the fact my world has its ice caps melted and there is a volcanic basalt trap in the middle of America would be pretty significant, but social-politically no environmental stuff was as important as these three events.
The most important was done so backdoor by Congress that it went unnoticed by most except those who needed to know.
