Part of the question is, assuming the globe is warming, on a global
scale is that even a problem? In historical times there have been
times that the globe was warmer than it is now, and it was not a
problem before.

Chicken little says it very well could be a problem. There is a lot of
mass here, and a little warming is easily absorbed. The question may be
whether there is a tipping point, and where that is. Little ice ages and
warmer periods have occurred regularly (Pinatubo eruption had a small but
measurable effect). The real Cassandras say that if the arctic thaws, so
much methane may get released from frozen hydrates that we will get big
warming on a global scale. Etc, etc.
