Abstract
Rising temperatures on earth especially during the later half of the twentieth century have been largely attributed to increasing greenhouse gases (GHG) levels in atmosphere, due to worldwide growth in fossil fuel consumptions by the industrialized nations. Though there are several other offspring of industrial revolution other than GHGs, e.g., increased atmospheric water vapor, aerosols, which also may affect terrestrial climate in either way on shorter timescales, understanding their net role in terms of climate change on regional to global scale remains limited (IPCC 2007). In aggregate, though anticipated anthropogenic climate changes have generated immense curiosity, concerns and lucid debates among intellectuals, scientific experts as reported by Rockstörm et al. (Nature 461:472–475, 2009) broadly agree that deeper understanding is required on how these anthropogenic drivers mutually interact among themselves and most importantly with natural drivers in terms of their net climatic impact. In this communication, we intend to put forward some of the established facts of anthropogenic climate change, projected vulnerabilities of immediate concern and important knowledge gaps that are yet to be explored and understood.
