What can we do about climate migration?

Bangladesh is a country that is exceptionally vulnerable to
climate change. With a low elevation and high population density,
as well as poor infrastructure and an economic reliance on
farming, it is naturally susceptible to extreme weather. The
intensification of conditions due to climate change means more
people are being driven from their homes and land by sea level
rises, storms, cyclones, drought, erosion, landslides, flooding
and salinisation of the land. It's estimated that by 2050, one in
every seven people in Bangladesh will become a climate migrant.
But Bangladesh is far from being alone. Across South Asia, it’s
estimated that more than 40m people will be displaced; worldwide,
the figure runs into the hundreds of millions. Climate migration
is coming. The question is, what are we going to do about it?
