Original sentence: " In other words, how likely is it that temperatures would go up by 5.8 degrees Celsius, or 1.4 degrees Celsius, which represent the IPCC's respective upper and lower bounds." That, he said, "depends on the likelihood of the assumptions underlying the projections." These storylines, he wrote, "gave rise to radically different families of emission profiles up to 2100 - from below current CO emissions to five times current emissions."But this inference would be incorrect," said Schneider, "because uncertainties compound through a series of modeling steps.But as Schneider wrote, the group drafting the IPCC report decided to express "no preference" for each temperature scenario.In effect, this created the assumption that the higher bound of 5.8 degrees Celsius appeared to be just as likely as the lower of 1.4 degrees Celsius.In his article, Schneider asks, "How likely is it that the world will get 6 degrees C hotter by 2100.Schneider says that he "strongly argued at the time that policy analysts needed probability estimates to assess the seriousness of the implied impacts.Stephen Schneider commented on the IPCC's assumpt…ions in the journal Nature on May 3, 2001.The assumptions, he wrote, are "'storylines' about future worlds from which population, affluence and technology drivers could be inferred
