| Abstract | Summary form only given. The balance of evidence suggests that the climate is not warming. A US National Research Council report has highlighted, but not explained, the disparity between different data sets: while a variety of surface thermometers report a substantial warming trend, microwave sensing units (MSU) on weather satellites, and also radiosondes carried in weather balloons, show little if any warming of the atmosphere in the last twenty years. As is well understood, however, climate models predict the opposite, namely a stronger warming trend for the atmosphere than for the surface. In further investigating this puzzling discrepancy involving different observing methods as well as theoretical models, the authors hypothesize that the recent surface trends may not be credible. They note that while there is general agreement that the global climate warmed before 1940, and then cooled slightly until about 1975, the well-controlled surface temperature data for the United States and Europe do not show any appreciable post-1940 warming, after correction for local urban warming ("heat islands"). This lack of warming throws doubt on the reported global surface trend. Further, proxy data from tree rings, ice cores, etc. show no post-1940 warming trends; many even show a cooling trend after 1940. The observations of Arctic sea-ice shrinking, deep-ocean warming, glacier-length changes and sea-level rise are explained as a delayed consequence of earlier climate warming; they are all in good accord with the hypothesis that the Earth's climate has not warmed appreciably in the past 60 years. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built 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 designed 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 developed, operated and maintained from 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 Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
