So I've showed the thread and forum to Dick Mol. He wants to join the fun and also make useful contributions on Pleistocene mammals.

However on the moment he is extremely busy with projects in Russia, USA and Greece. And the few days in between he is travelling from meetings to events to appointments. There is a huge Homotherium exhibit in the Rotterdam Natural Museum about the last Sabre tooth cats in Europe which requires most of his attention at the moment.

So no time for internet at the moment but in a few months he'll join and ge'ts us the real first hand information.

It appears to me that one of our controls is wrong. Either we are mistaken about the global nature of the last glaciation, or the radio carbon data is wrong. Is there another possible explaination that I miss here?

Hi Andre,

Your thoughts about the changes taking place during the end of the LGM and how they may have rendered conditions unfavorable for the Mammoths are supported by something someone said on a Climate blog... I'll post the link after the quote:

Thanks for the link, actually there are a few conceptions. mammoths did not care a lot about temperature, but more about the isostope: steppe and steppe only. Warm or cold would not matter. They were obvious grazers and the large tusks would have been very inconvenient for manouvring in between trees. They might have lived on the Canadian praries or Mongolian steppes nowaday. As long as winter snowfall would not cover the grasses they would be okay.

Also from the blog, numerous climate fallacies. It's not about if the glaciers are expanding or shrinking. It's not about the cause for that, either or both warming or aridity. The climate discussion is whether or not increasing concentrations of radiative gasses are causing considerable warming. Shrinking glaciers do not proof anything about a possible cause of glacier behavior. Some glaciers may grow in warmer conditions as it also facilitate more snow fall.
