The picture of mass cross-border climate migration is not correct. According to NRC journalist Paul Luttikhuis citing migration researcher Ingrid Boas in a Dutch newspaper NRC Handelsblad in October 2018.
According to Boas, leaving somewhere to never return is an extreme move. When people have to leave their home, they return as soon as possible. And if departure is ultimately inevitable, people will go to nearby regions and will not migrate internationally. She bases her studies on areas in Bangladesh where climate change increasingly influences daily life.
The figure of more than 200 million climate refugees in 2050 (by Norman Myers) is, according to critics, ‘guesswork’. It assumes that people are more willing to leave a country than they actually are.
