      More Details Abstract Fulltext PDF

      A distinction is made between the greenhouse effect and the increased or enhanced greenhouse effect. The radiation budget of the atmosphere is reviewed, and a simple balanced model is designed permitting the calculation of a mean surface and a mean atmospheric temperature. The increased greenhouse effect is simulated by the model. Various calculations illustrate the sensitivity of the model to changes in the planetary albedo and in the absorption coefficients.

      The climate system is reviewed followed by a description of the simulations of the increased greenhouse effect with climate models. The observed climatic record is described with emphasis on whether or not the increased greenhouse effect can be detected in the data.

      Some proposals for future research are made. The social and economic issues connected with the enhanced greenhouse effect are discussed. The paper contains finally, the main conclusions.
