Global Warming and its effects on the coastal areas

Indian Coastal areas would be severely affected, if the climate change or increase in the temperature by 4%, the sea would engulf major cities across the Globe.

An US-based non-profit research and journalism organization, Climate Central,  has warned that the climate change threatens nearly 55 million people in India's coastal areas and increase in temperature could submerge a whopping 145 million in China also.  This could lock in enough rise of sea level to submerge land currently home to more than half a billion people globally if the temperature spikes by four degrees Celsius, which is humanity's current trajectory and remains a serious challenge environmentalists.

The report further stated that A 4C warming scenario could lock in enough sea level rise to submerge land inhabited by half or more of today's population in Shanghai and Shantou, China; Haora (Howrah), Calcutta and Mumbai, India; Hanoi, Vietnam; and Khulna, Bangladesh.
