Climate change will displace millions of people - do we need to rethink attitudes to mass migration?

Mass migration towards the Earth’s poles will help humanity survive the climate crisis, in keeping with a recent book.

The planet could warm by greater than 4 degrees Celsius by the tip of the twenty first century.

This can leave vast areas of land uninhabitable and force thousands and thousands of individuals to search out recent homes, warns creator and climate journalist Caia Vince.

In her recent book Nomad Century: How Climate Migration Will Reshape Our World, she argues that we must always ditch outdated border controls and embrace mass migration.

“People could have to maneuver (from) unliveable places,” she said at a Royal Society of Arts talk on Thursday.

“We want to administer migration in order that it will not be a catastrophe… but a protected, productive transition right into a sustainable future.”

How many individuals could have to migrate due to the climate crisis?

The changing climate is already forcing people to desert their homes.

In keeping with the United Nations High Commissioner for Refugees (UNHCR), around 21.5 million people have been forcibly displaced by weather-related events since 2008.

The Institute for Economics and Peace – a London based think tank – estimates that around 1.2 billion people may very well be displaced by climate change over the subsequent 30 years.

As floods, fires, and heatwaves change into more common, some regions of the planet will change into borderline uninhabitable.

Vince cites Mumbai – where 9 million people live in slum housing – for instance.

“There isn’t any way that these 9 million people can have air con of their slums,” she says, adding that they recurrently face power outages during heatwaves.

“This can also be the case large parts of Bangladesh, also the case for places across Africa, across the Americas, there are places that is not going to give you the chance to adapt to those extreme temperatures.”

How should we cope with climate migration?

Migration to northern latitudes is inevitable, Vince says – and it shouldn’t be seen as a foul thing.

Populist governments… mainly use migrants as a scapegoat for all the things, for job problems, for failing social security and welfare systems,” she says.

“But so many studies show that migrants increase the wealth, increase the productivity of cities where they integrate well.”

This influx of individuals will enrich cities in the worldwide north, the creator argues. For instance, it could help fix demographic problems in places like Europe where the population is regularly ageing.

The climate journalist poses numerous different solutions. One option is for the United Nations to supply ‘global citizenship’ to people, a category that will operate alongside existing national citizenships.

On a national level, governments should allow recent arrivals to work, legally pay taxes, and take part in society.

Will the earth warm by 4 degrees?

Within the 2015 Paris agreement, the international community agreed to attempt to limit warming to 1.5 degrees Celsius above pre-industrial levels.

But in keeping with the Climate Motion Tracker, we’re heading in the right direction for two.7 degrees of warming by 2030.

The earth could plausibly warm by 4 degrees, Vince says, as we pass ‘trigger points’ sparking vicious cycles of irreversible change.

If permafrost – which covers 1 / 4 of the landmass within the Northern hemisphere – thaws, it can release huge amounts of CO2 and methane into the atmosphere.

“There may be actually quite a serious risk that we do hit these catastrophic temperatures,” Vince warns.

“We must be honest with people about exactly what we’re facing.”

These risks make it all of the more urgent to overhaul our migration systems.

“The longer term may be very much unwritten… now we have many possibilities,” she says.
