Another possibility is that Europe received enough immigrants from more
densely populated areas to compensate the greater mortality, be it caused
by auroras or coldness or something else.

 I'm in the middle of Steven LeBlanc's "Constant
Battles", pub 2003. Dated a bit, I suppose, but
does have a lot of useful odds and ends. (The
relating of Eskimo warfare was something else,
they were willing to spend 10 or more days
traveling to kill another group.)
 The migrants may well have had a tech edge in a
time of changing climate etc as well as no
compunctions about knocking off the current
tenants.

Meant to include this

Projectile weapon injuries in the Riparo
Tagliente burial (Veneto, Italy) provide
early evidence of Late Upper Paleolithic
intergroup conflict
The dates are too young - 17Kya to 15.5kya - for
the neanderthal scenario but old enough to suggest
warfare, raids, etc. Neanderthals may not have
had the reproductive replacement capcacity to
compensate for population losses. In such conflicts
it not unusual for the women of attacked groups
to be taken alive which could explain admixture
of genes.
