Re: Business as usual.
Yup, wherever there's a lot of money to be made take the 'facts' presented with a pinch of salt. There's a correlation between self-serving bullshit and revenue/chance of revenue in everything.
Even you, dear reader, will massage information on your CV using (doubtless) accurate wording which you've changed to create the impression you want in your client's/employer's head.
The difference is you stand to make a few thousand from your employer so the lies are smaller than if you stand to make a few million. If I thought I stood to get a few million based on what I wrote in a paper you can be damned sure I'll write what I think will make me more likely to get it.
If anyone thinks the IPCC and its chums don't have an agenda they're deluded.
