Saudi Arabia has signalled the sinking of the useless talkfest before it starts.
Saudi Arabia is an influential member of the G77/China bloc which leads the "developing world" side in many elements of the UN negotiations.
Mr Al-Sabban made clear that he expects it to derail the single biggest objective of the summit - to agree limitations on greenhouse gas emissions.
"It appears from the details of the scandal that there is no relationship whatsoever between human activities and climate change," he told BBC News.
"Climate is changing for thousands of years, but for natural and not human-induced reasons.
"So, whatever the international community does to reduce greenhouse gas emissions will have no effect on the climate's natural variability."
Some other countries shared this view, he said; and as a result, governments would not be prepared to countenance agreeing anything that would affect economic growth for many years, until "new evidence" settled the scientific picture.
The house of cards continues to tumble down.
Long may it continue.
