Sorry I wandered on to this thread so late in the discourse, but there was a warm period in Europe from about (if memory serves me) 1100 to 1300. We’re talking major warm winters and stifling summers. You could even call it G——l W-——g. No, seriously, fleas could have survived those winters.
Ha. Just what I suspected- yet another rat-basher.
There is no end to the oppression.
