Peter Singer's Q&A comments about climate refugees stack up

UNSW's Jane McAdam writes about
Peter Singer's "750 million climate
refugees" comment on Q&A.

Ethicist Peter Singer told Q&A that climate change-related sea level rises are “estimated to cause something like 750 million refugees just moving away from that flooding”.

It is beyond the scope of a FactCheck to say with any certainty what will happen in the future. And there is no single official data source on the numbers of people who migrate because of the impacts of climate change, partly because there is no legal definition of a “climate change refugee”. Furthermore, most such displacement occurs within countries, not across international borders, and is always due to a number of different factors. Finally, there is no systematic monitoring of such movement.

That said, we can check how Singer’s figure of 750 million fits within the range of estimates that exist on this question
