Climate change 'will create world's biggest refugee crisis'

Experts warn refugees could number tens of millions in the next decade, and call for a new legal framework to protect the most vulnerable

Tens of millions of people will be forced from their homes by climate change in the next decade, creating the biggest refugee crisis the world has ever seen, according to a new report.

Senior US military and security experts have told the Environmental Justice Foundation (EJF) study that the number of climate refugees will dwarf those that have fled the Syrian conflict, bringing huge challenges to Europe.
