|Abstract||The NRC report A Plan for a Research Program on Aerosol Radiative Forcing and Climate Change underscores the importance of anthropogenic aerosols as agents of climate change. However although the NRC report stresses the need to reduce the uncertainties of the influence of aerosols on climatic change, the authors feel that this is not sufficient. Climatic influence of aerosols is complex. The presence of anthropogenic aerosols is thought to have roughly doubled light scattered back into space. In addition increased aerosol particle concentrations enhance cloud reflectivity and inhibit precipitation development, causing more persistant clouds and more sunlight reflection. The decrease in absorption of solar radiation (the forcing of climate) is estimated to be comparable, but of opposite sign to climate forcing resulting from increased absorption of terrestrial infared radiation by enhanced atmospheric concentrations of greenhouse gases. This article discusses both the findings of the NRC report and other views of the issue. 9 refs., 1 fig.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is being developed to help students to prepare for entrance and competitive examinations, to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is being developed at Indian Institute of Technology Kharagpur.
NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
