jeez, what's with all the propaganda video links, is someone trying "convert" the heretics?

We get it, you have religion, do you mind not going all evangelist on us bonmot.

It's not science, it's just propaganda videos, which apparently, you like very much, yay for you!

sorry, meant deep blue .. who seems familiar somehow .. been here before under a different tag?

That's ok rpg, I tend to agree - 'deep blue' seems appropriate to the moniker.

I tend to stay clear of extremists from whatever direction they come from and if that applies to 'deep blue' so be it. That being said, I suspect the videos he has linked to are pertinent to his argument - when I have the time I might watch.

If Dr Ollier was, a glaciologist or had any reputation in this field, one would have expected to find that he had at least one peer-reviewed publication to his credit. His only paper published in a reputable journal (Geoscientist, March 2010) was roundly discredited and shown to be wrong by Michael Hambrey et al. (Geoscientist, April 2010) who come to the conclusion that …

“Ollier argues that ice sheets are inherently stable (1) because current patterns of flow are unrelated to modern climate, (2) because basal lubrication is not important, (3) because meltwater does not form on the surface of ice sheets, and (4) because iceberg calving dynamics do not influence the interior of ice sheets. Above we have explained why each of these assumptions is incorrect.”

Unlike his Geoscientist critics, Ollier is not a glaciologist and does not know what he is talking about.

Agnostic:

You'll have to do better than this. Climate is a vast field, and no one is expert in it all. You can prefer someone else's account to Professor Ollier's, but it would be helpful if you showed why you do. Are you able to read all the material and come to a considered view yourself? One of the problems with all this is that there are thousands of articles, and they point in many directions. I don't know which ones are right, and no one else does either.

But I think you can say that the science is by no means settled, and until there is more understanding, and more knowledge, it would be sensible to travel slowly in policy terms.

But sledging people who are knowledgeable doesn't seem to me either creditable or useful.

Agnostic: just because Ollier (along with John Nicol, Bob Carter, David Evans, William Kininmonth, John McLean, Ian Plimer, Tom Quirk and a few others advising the Australian Climate Science Coalition) thinks human induced climate change is the greatest hoax that the scientific community has inflicted on mankind does not mean he doesn't know his geology or soil science, he clearly does.
