A backstory for a science fiction novel I am writing involves mapping out some of the devastating consequences of climate change and a simultaneous water crisis in Bangladesh. I'm curious about your input on future directions and improving this portion of the tale.
The setting is around the year 2100 with a hypothetical (though plausible) 3C temperature increase. Sea levels have risen by about a meter. Consequences of this climate change unfolds as a water shortage compounded by major flooding due to a powerful typhoon. These events unfold in Bangladesh in an event referred to as the "Bangladesh Water Crisis."
The net effect is the massive migration of millions of people - but my (albeit limited) understanding of geopolitics in this region is that Bangladeshi refugees are not exactly desired in the neighboring states of India, Myanmar, or China (to the far north). The result of this humanitarian crisis is military action from surrounding countries, leading to the death of millions of people.
I'm interested in identifying one or two major cities that are particularly susceptible to flooding / water damage, along with the most likely path that refugees would take to leave Bangladesh.
Thanks for reading. Please consider providing a name for the typhoon. If I select your answer, I'll consider including the name you choose for the typhoon in the book :).
