This is appropriate given that two posts later, WUWT reveal what Professor Mann claims is science to be believed, when his computer-modelled graphs and predictions right from the start use a 2013 global temperature level already incorrect. That’s how their ‘warmist’ science “works”.
From this post we learn the importance and influence of the agenda factor – “Here is the IPCC procedure:

“Changes (other than grammatical or minor editorial changes) made after acceptance by the Working Group or the Panel shall be those necessary to ensure consistency with the Summary for Policymakers (SPM) or the Overview Chapter.”
Blatant admission from the IPCC that reports are amended to prove the premise that ‘man is causing catastrophic warming’. You can’t find anything clearer than that. Yet warmists persist in their false (demonstrably) claims and scaremongering lies.
