You mention the Holocene Maximum. It's my understanding that about 10,000 years ago the climate was much warmer than at present. It then cooled again and gave rise to what used to be called the Younger Dryas vegetation. Forest returned to europe as the climate warmed again after this. I'm sure it would be easy to find links.
