YMB explains that the various bits of cuneiform mystery and their associated exclamation marks mean that sections are "comment out" -- erased from public view, in other words -- presumably when someone at the Climate Council realised that the original video link would not do much to advance the cause of separating the gullible and indignantly self-righteous from their cash. Indeed, it would have been a powerful disincentive to heep hands well out of pockets
Here is the video, according to YMB, which the Climate Commission originally intended to present.
As can be seen, there were some very rash predictions tumbling from Flannery's lips in 2010, none of which has come true or is likely to. (No need to endure the full clip;the funny bits about polar bears, massive rises in sea levels and the certainties of experts are near the start). Much safer, on the whole, to have Flannery talking about "the science" and his cause's need for cash, as he does in the substitute video.
Sadly, Flannery does not address the climatic imperatives that persuaded him to leave Mrs Flannery to fill the sandbags at the waterfront home he formerly shared with her and seek higher ground with a prostitute-turned-author. Donations to the Climate Council should be placed beneath the big pink dildo on the night table (the black one is reserved for solstice celebrations).
UPDATE: YMB wishes to make it clear that he did not discover the hidden code. Rather, he was alerted to it via an email now doing the rounds.
