Social "cost" of carbon dioxide, or benefit.

When the FUND integrated assessment model (IAM) is run using the Lewis and Curry analysis of climate sensitivity adjusted for the millennium warming cycle and the urban heat island effect, TCR = 0.85 C, warming 1916 to 2100 = 0.57 C, the model gives a best estimate of the social cost (benefit) of carbon dioxide of US$ -16.7/tCO2, with a likely range of US$ -19 to -12/tCO2, assuming a 3% discount rate. That is, warming on a global basis, CO2 emissions are very beneficial when a realistic transient climate response is used.

Other IAMs PAGE and DICE fail to include the benefits of warming and CO2 fertilization and should not be used to estimate the SCC for policy making.
