Nations of the world collectively acknowledged the tell-tale signs of climate change and came together to formulate and commit to a global action plan with concrete deliverables in 2015 under the Paris Climate Change agreement. The agreement targeted various deliverables including a committed effort to keep the global average temperature increase well below 2 degrees Celsius and to pursue efforts to limit it to 1.5 degrees Celsius above pre-industrial levels. However, the efforts have not been seeing much success since then. The two key reasons for the less-than-expected success were the lack of the technology transfer from the western world and the failure of the developed world to deliver on its decade-old promise of mobilizing at least US $100 billion every year from 2020. While some of the countries including India have taken a conscious decision to pursue the self-driven path of sustainability and ecological balance, the larger world has slowly been becoming more and more vulnerable to man-made events related to climate change. The threat of submergence looms large on about 570 cities of the world by 2050 and out of these 12 cities may belong to India alone.
