Abstract
The changing climatic trends within just last one decade have compelled the global security analysts and climatologists, to start discourse on the emerging non-traditional security scenario. The climate was and would remain the life-line of the inhabitants on the planet earth that reside inside national boundaries. Broadly, climate change has been recognized as the broad-spectrum threat multiplier with grave security implications. The successive extreme events across the globe such as mega-flooding and repeated cyclones besides tsunamis have raised alarms amongst the security analysts globally. These events have disastrous impacts on the very survival of many states and call for climate security focused research work. The policy makers and climate experts thus need to fully comprehend the climate security implications. The emerging climate security and survival discourse would be of immense value for national Defense and strategic planners. The article argues that climate change has turned out as matter of existential issue for the survival of the state and humanity at large as it does not recognize traditional national boundaries. Thereby the political leaders, policymakers especially strategic planners need to design new pathways to respond to challenges of future sustainable development and pursue a proactive climate diplomacy.
