Scholars Question Global Warming

A scientist studying the environment for 50 years has documented the scholarly dissent against prevailing theories of global warming. Dr. Madhav L Khandekar recently published a 23-page annotated bibliography that contains selected peer-reviewed papers on the following areas:

1. Temperature reconstruction using proxy data; the Hockey Stick Graph
2. Impact of solar variability on the earth’s climate
3. Sea-level rise, ocean surface warming/cooling etc.
4. Arctic and Antarctic temperatures: from Holocene to present
5. Impact of large-scale circulation patterns
6. Extraneous influence on mean temperature trends: urbanization, land-use change etc.
7. Uncertainties in climate model simulations
8. Miscellaneous studies

His conclusion is that global warming is not as marked as has been reported, and whatever warming has occurred has little to do with carbon emissions. Urbanization, land use changes, solar activity, and weather cycles are larger factors. Moreover, extreme weather is not occurring more frequently--but our ability to monitor it and the media hype around it has grown significantly. Temperatures in past eras were just as warm, and the northern ice caps were even smaller. To top it all off, the science of weather projection in the longer term has not made significant progress over the past fifty years, meaning alarmist end-of-the-world predictions based on such weather models has a dubious basis.

Dr. Madhav L Khandekar is a former Research Scientist from Environment Canada where he worked for about 25 years. Khandekar holds M.Sc degree in Statistics from India and M.S. and Ph.D. degrees in Meteorology from USA. Khandekar has been in the fields of atmosphere/ocean/climate for over 50 years and has published over 125 papers, reports, book reviews, scientific commentaries etc. He has published over 40 peer-reviewed papers in various international Journals and authored a book on ocean surface wave analysis and modeling, published by Springer-Verlag in 1989. Khandekar is presently on the editorial board of the Journal Natural Hazards(Netherlands) and is a former editor of the journal Climate Research (Germany). He was an expert reviewer for the IPCC (Intergovernmental Panel on Climate Change) Climate Change Documents (AR4) published in 2007.
