This is striking new finding by ABC journalist Ann Arnold that for some reason has not yet been published in a science journal.
Some mystery remains, however as to which dataset could rule out any and all fires in the last 30,000,000 years, or indeed which dataset could prove that those forests and trees have existed in the same place continuously. We keenly await more details on the high resolution sedimentary pollen and missing ash deposit that could show that there were never fires, especially during the miocene when Antarctica thawed around 24 million years ago and .
It’s all the more remarkable given that temperatures have varied in the Antarctic by 15 degrees Celcius over the same period, and for 20 million years of the last 30, it was even hotter than today.
Scientists keenly look forward to seeing those error bars, though one critic, Dr Hyperbowlie suggested the p-values “might be greater than 1. ”
