"The difference between Plimer and Flannery is that Plimer has almost no climate credentials and is out on a limb with his hare-brained 'theories' whereas Flannery simply defers to the experts"
Actually flannery picks the experts he wishes to defer to and with his basic degree in english literature, it is likely to be a choice based on ideological grounds...
Whereas Professor Pilmer:
"Ian Rutherford Plimer (born 12 February 1946) is an Australian geologist, professor emeritus of earth sciences at the University of Melbourne,[1] professor of mining geology at the University of Adelaide,[2] and the director of multiple mineral exploration and mining companies.[3] He has published many scientific papers, six books and is one of the co-editors of Encyclopedia of Geology.[4][5]"
