Looks exponential to me. Particularly from 1999 on, where there's a sharp upturn. The developed countries emissions are flattening because a large proportion of their production is being outsourced to China: http://www.google.com/publicdata?ds=wb-wdi&met=en_atm_co2e_pc&idim=country:CHN&dl=en&hl=en&q=chinese+carbon+emissions#met=en_atm_co2e_pc&idim=country:CHN http://www.google.com/publicdata?ds=wb-wdi&met=en_atm_co... The main issue is that we may not have 100 years - that's just a figure that Lomborg has come up with, and his figures are doubted by a lot of climate scientists. Somewhere around 2degC (over 1999 levels) is about the point where we might start to see positive feedback and serious effects from warming. At our current rate, we'll hit that in about 2040-2050. 5degC is certainly possible by 2100, which means no glaciers/fresh water in India/Pakistan/Bangladesh, desertification, food shortages and a couple of metres of sea level rise.
