The general theory is that the last ice age, Last Glacial Maximum, or LGM, was about ten thousand years ago and lasted from between ten thousand to fifty thousand years, during which, any human population living in the LGM region - generally known as the Scandinavian Ice Sheet - moved south to warmer climes, until the ice slowly melted and then they moved back some eight thousand years ago.
Could small pockets of human communities have continued to live north of the Scandinavian Ice Sheet (the centre of which at it thickest depth was at the area known today as Sweden's mountainous region)? In other words, is it possible, as some evolutionary scientists have suggested, that there was a whole group of humans who didn't travel south but remained as a separate group for up to fifty thousand years?
To back up this theory, scientists have now discovered that, far from all the trees in Sweden dying during the LGM, many did not die at all, suggesting the environment was sustainable to life.

This is referring to trees but if plant life could live, then so theoretically could some animal life, including humans.
You might say that it would have been too cold to the north of this ice sheet but remember, what are seas and oceans today may have once been dry land before the LGM glaciers melted away. The Baltic was originally a small lake! In addition, temperatures were distributed differently with the north not necessarily always equating to 'the coldest'.
Scientists have calculated likely temperatures during the LGM:

So if that was an average 8°C or 46°F over the Scandinavian Ice Sheet, then it could have been a few degrees warmer the further away people or animals could have got from it, even northwards.

Up to now, most scientists have subscribed to the general view that the advancing ice presented all living things with an ultimatum: Go south or die out! But now an international research team claims that the glaciations has not been total, and that there must have been some retreats with ice-free areas where trees could survive tens of thousands of years of glaciation. |

Tierney is lead author of a paper published today in Nature that found that the average global temperature of the ice age was 6 degrees Celsius (11 F) cooler than today. For context, the average global temperature of the 20th century was 14 C (57 F). "In your own personal experience that might not sound like a big difference, but, in fact, it's a huge change," Tierney said. She and her team also created maps to illustrate how temperature differences varied in specific regions across the globe. |
