In the comments below there is some mention of the problems that Bangladesh will face due to increases in global sea level. The hypothesis is that there will be a mass migration to India as Bangladeshis flee low-level zones which are going to be inundated. I don’t think this is capturing the real issue: if millions of Bangladeshis are still subsistence farmers on marginal maritime zones then there has been a massive development failure.
Even extreme sea-level scenarios by 2100 posit a 2.5-meter rise, which means only a small proportion of the territory of Bangladesh would be inundated. If by 2100 Bangladesh is not a predominantly urban society after 80 years of economic development from 2020, there are much deeper structural problems to deal with than climate change.
Development and wealth change the downsides of risk a great deal. The 1970 Bhola cyclone caused hundreds of thousands of deaths. Something that is unlikely to be replicated in the region for various reasons (e.g., information technology and coordination are far better!).
I’ve been paying attention to climate change since the late 1980s. As someone whose family is from Bangladesh I have been very worried…my image in 1990 was of peasants fleeing inundated paddies. But things have changed a great deal. In 2020 nearly 40 percent of Bangladeshis live in cities. By 2100 a substantial majority should…
