The two models chosen by USNA team are clearly outliers from the family of available models. The Canadian Climate Centre model (acronymed by the USNA as CGCM1) is one of the very few that produces a substantially exponential (rather than linear) change in temperature. The other model used by the team is known as the Hadley Centre Model (acronymed by the USNA as HadCM2), developed at the United Kingdom s Meteorological Office.6... 

Note Notice that the Hadley Centre Climate Model (HadCM2, heavy broken line) produces the most extreme precipitation increase the Canadian Climate Model (CGCM1, heavy black line) produces the second largest increase.

The expense of such multifactor experiments has led scientists to use process-based ecosystem models (see the discussion of terrestrial carbon models below) to predict the response of terrestrial ecosystems to future climates. When predicting the effects of CO2 alone, six global biogeochemical models showed a global terrestrial sink that began in the early part of the twentieth century and increased (with one exception) towards the year 2100 (Cramer et al., 2001). The maximum sink varied from 4 PgC yr to —10 PgC yr. Adding changes in climate (predicted by the Hadley Centre) to these models reduced the future sink (with one exception), and in one case reduced the sink to zero near the year 2100.
