| contents | Feedback effects of atmospheric CO2-induced warming Julián Adem René Garduño Ciencias de la Tierra warming feedbacks Atmospheric CO2 Using a thermodynamic climate model, temperature and precipitation changes due to a doubling of atmospheric CO2 content,including the corresponding feedback temperature increases of water vapor, snow-ice, and cloudiness, are evaluated. The feedbackfactors of the thermodynamic model are similar to those of Hansen et al. (1984) and Schlesinger (1986). The feedback factorof all three mechanisms combined is 4.0. The results depend mainly on the content of water vapor in the CO2 band (12-19m). Thetemperature increase due to a doubling of CO2 is 1.2° C when there is water vapor in the band, and 3.5° C when there is no watervapor. Therefore, a possible cause of the strong differences in the solutions obtained by different models is the discrepancy in theamount and distribution of water vapor in the atmosphere, and in the treatment of its effect in the CO2 band. 1998 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56837201 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.37 |
