The last-minute wrangling is likely to affect the degree of certainty in the final version, the BBC's Richard Black reports, but not the overall direction.

Draft versions seen by BBC News warn it will be hard for societies to adapt to all the likely climate impacts.
The report is set to say that a temperature rise above 1.5C from 1990 levels would put about one-third of species at risk of extinction.
More than one billion people would be at greater risk of water shortages, primarily because of the melting of mountain glaciers and ice fields which act as natural reservoirs.
The scientific work reviewed by IPCC scientists includes more than 29,000 pieces of data on observed changes in physical and biological aspects of the natural world.
Eighty-five percent of these, it believes, are consistent with a warming world.
